A constant torque spring can play such a big role in the take-up device
A constant torque spring can play such a big role in the take-up device
Constant torque springs can help take up the wire and are used in many products. All electrical products have a cord set that is connected to the power supply, but this power cord will bring some trouble to our arrangement. The function of the constant torque spring is this, it can bring a free shrinkage process to the electrical cord set , making it easy to take up the line, very practical. When the external force reverses the constant torque spring from the natural state to the output wheel, once the external force is removed, the constant torque spring will be rolled back to the natural state, and a constant torque will be generated in the output wheel at the same time. Constant torque spring can be used in automatic winding, balance weight and power source, such as automatic winding device of power line. Advantages of constant torque spring over power spring: 1. The torque will not change as the number of turns increases. 2. There is no limit on the number of...

Wissen Sie, welche Federn als Stoppmechanismen verwendet werden?
Wissen Sie, welche Federn als Stoppmechanismen verwendet werden?
We often find that the spring we make is wrongly used as a stop mechanism in the design. This design defect can occur in all types of springs, including constant force spring, constant torque spring and power spring. For example, consider a simple cable extension product in which the spring retracts the cable into the housing. If the spring is completely wound before the cable is fully deployed, the spring will be used as a stop mechanism. This action will damage the function of the spring and components and should be avoided at all costs. Here are some useful tips when considering the stop mechanism. Constant Force Spring Application:  Initial designs often show the inner end of a Constant Force Spring attached to its’ spool. This is not necessary.  If the spool is larger than the natural spring diameter, the spring will automatically fit tightly on the spool.  In the case when a screw is attached to the spool, additional concerns...

 The power spring makes the tape measure shrink freely
The power spring makes the tape measure shrink freely

Zeit: 2022-9-14

Tape measure, I believe everyone is familiar with it. Tape measure is a common measuring tool in our daily life and work. After the tape measure is pulled out, it can be rolled up because there is a power spring in the tape measure. When pulling out to measure the length, it actually lengthens the length of the scale and spring. Once the measurement is completed, the spring in the tape measure will automatically shrink, and the tape will also shrink under the action of spring force, so the tape measure will roll up. The power spring is an elastic fitting in the tape measure. The end of the steel bar scale is connected to the front end of the spring, and the end of the spring is fixed in the middle of the tape measure. The tape measure mainly uses the energy storage characteristics of the spring, which can be said to be the conservation of mechanical energy .When you pull the tape measure, you work on the internal spring, and the energy is stored by the power spring; when you release it, the spring relaxes, releasing energy and causing the tape measure to retract automatic contraction uses the lever torque principle: in the stretching state, the force arm is the smallest and the spring output is the largest; in the retracted state, the force arm is the largest and the spring output is the smallest.         When the scale is pulled out, the spring is tightened to produce a force to roll back. When the tension of the scale is released,...

  Purchasing special components for equipment is always an obstacle for engineers designing new products. Many industries, from automotive and aerospace to medical and construction, need to customize springs for special applications. Spare springs are ideal for short turnaround times, but they are not suitable for your equipment specification. To this end, custom springs may be an important solution for industrial engineers. Learn more about some of the benefits associated with custom springs.     1、Design expertise    Using stock springs may mean that you must meet the approximate values you need. However, custom springs can be made to match the specifications required by your equipment. Custom spring manufacturing brings extensive knowledge of different types of springs to your project, including how to manufacture components to meet product requirements or specifications. When you work with spring manufacturers with design engineering expertise, your company can also reduce other costs.     2、 Flexibility   Custom spring manufacturing reduces turnaround time associated with orders and revisions. Maintain stricter control over the supply chain. If the components you ordered need to be adjusted, you can make these adjustments more directly. This gives you more flexibility to experiment with designs and adjust to product recalls or industry changes.     3、 Reduce production costs    Manufacturing partners with their own internal tool capabilities are usually able to complete large custom orders. This is due not only to their professional manufacturing technology, but also to the reduced costs associated with transporting and handling parts. You can also avoid indirect costs of labor, manufacturing equipment and raw...

Advantages of Qianye power spring in electrical take-up

Zeit: 2022-9-14

As we all know, take-up spring can help take-up. It is used in many electrical products, and hair dryer is no exception. However, all such household appliances have a common feature, that is, they need a wire group to connect the power supply. However, this power line will bring some trouble to our sorting. The function of winding up lies in this. It can bring a free shrinkage process to the electrical wire group and make its winding up easy and practical. In fact, although the process of electrical wiring is not a high-end principle, it is better than cleverness. Its working principle is not complicated. It uses the spring box to limit the outer diameter, so that the center of the spring is connected with the power shaft. When the line is pulled out, it can make the shaft and the spring rotate relatively, and the spring will roll on the power shaft and store the corresponding kinetic energy. When the external force disappears, the spring will generate torque to drive the power shaft, so that the line can be retracted back into the box. In the take-up function of the reel, the effect of the power spring can not be underestimated. It can often help the required goods to take up the line quickly and simply, and become an auxiliary software favored by people. It is also due to the spring to store kinetic energy. It uses the characteristics made by the spring bearing force, and effectively uses its mechanical energy storage and driving force output, so that...
 Variable force spring in drug delivery device
Variable force spring in drug delivery device

Zeit: 2022-9-14

Devices for automatically delivering drugs, such as automatic syringes, are known as convenient and safe means of protection for patients to manage different drugs themselves. For safety reasons, many devices for delivering drugs include covers and other devices that protect users before and after use, such as injection needles. Different devices for transporting drugs are different in their overall design settings. They all have a mechanism for automatically transferring the contents of pre filled and pre filled containers, and there is no need to manually force the contents of the containers into the patient through the transmission components, namely needles and nozzles. Automatic delivery mechanisms in devices used to deliver drugs usually include compression coil springs. The challenge in the design of such springs is to balance the need for sufficient force at the end of the stroke and the need for less force during storage that will overload other parts of the device (when the spring is fully compressed).   The problems caused by conventional coil springs in drug delivery devices can be overcome by variable force springs. A novel device for delivering drugs, which includes an elastic member (60), a driving mechanism (50), a holding mechanism (40) and a starting mechanism, the driving mechanism has one end connected to a stop and a second end operably connected to the elastic member, the holding mechanism is used to loosely hold the driving mechanism in the first position, where in the elastic member has accumulated energy, The starting mechanism is operably connected to the holding mechanism for releasing the driving mechanism...

What do you think when you see the fire damper? I believe many people will think of "fire". In fact, the word "fire" must be familiar to everyone! What do you think of when you hear this word? People trapped by the raging fire? Or the scene of our brave firefighter uncle fighting the fire? The following are the fire events in recent days. At 14:00 on March 12, 2022, a fire broke out in the oil fume pipeline of a hotel in Huazhou City. At 3:46 on March 8, 2022, a fire broke out at the construction site of Jinke Xiangsheng Yueyuan at the intersection of chegang road and Xiyun road in Zhenjiang new area. In the early morning of March 14, 2022, a fire broke out in Kundulun District of Baotou City, which has killed 7 people so far. Do you feel very sad at this time? Uncontrolled fire is always a serious risk. In an emergency situation a fire can spread via a ventilation ductwork. Therefore it is essential that the ventilation ductwork is equipped with high-quality and robust fire dampers that also prevent smoke from spreading and therefore enable safety for escape routes. But what is a fire damper?     Fire Dampers are used in air transfer openings, ducts and other places where fire rated structures (e.g. walls, floors or other fire barriers) are penetrated. If these openings wouldn’t be protected, the fire would easily spread to other spaces and damage the property and pose a danger to people working/being in this environment. The idea...

Supermarkets and convenience stores can be seen everywhere. Now more and more people are developing retail. Traditionally, products on shelves are usually placed in order. Some merchants install automatic propellers. After customers buy products, the propellers will push The products at the back are automatically advanced, and when the customer wants to find this product, it is easier to see, which is convenient for the customer to find the desired product and stimulates the customer's desire to buy. Theft of small items in retail stores is a problem that occurs. An ideal form of anti-theft is to create time delays between the dispensing of multiple products. If there is a considerable delay between the distribution of individual products, thieves are less likely to steal the products.        A shelf-delayed pusher equipped with variable force springs can eliminate this problem. The propulsion system includes a pusher, a track and a stop mechanism. The propulsion system includes a resistance mechanism connected to the track and the pusher, and controls the forward movement of the pusher along the track, thereby controlling the speed at which the product is propelled for retrieval by the consumer. When engaged, the stop mechanism prevents the pusher from advancing the product, and the indexing mechanism also limits the forward travel of the pusher to a discrete distance.        The variable force spring can expand the negative gradient and the positive gradient into a spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are...

As people are becoming more and more picky about the beauty of home appliances, the problems of dirt, vulnerability and difficult placement caused by the exposure of power lines have been unsatisfactory. However, with the take-up device, the wires are completely stored in the internal space after use, and these problems are solved. Its core component is the use of winding up. Take-up spring refers to a kind of rotary spring that puts the steel strip crimped once or twice into the fixed box, and then connects it through the middle mandrel to tighten it to the predetermined position. After releasing the preload when necessary, it uses the rebound force of the rolled steel strip to achieve the design purpose.     The utility model has the advantages that the utility model is designed for rotary use, and can be widely used in the circular design device, and forms a coaxial design with the take-up device, which saves space very much.

In order to make the refrigerator operate effectively, the door should be kept closed. Keep the door open for a short time when putting or taking out food. However, opening it for a long time will affect its cooling and endanger food safety. It will also lead to excess power consumption. Fortunately, the modern refrigerator door can be added with a constant force spring to automatically close after you open the refrigerator for use. Nowadays, this kind of design is relatively rare in the market. It is generally a magnetic refrigerator door, which explains why the magnet is attached to it.   We have seen that it is essential to keep the refrigerator door closed all the time. If the door remains open for a long time, it will counteract the internal temperature balance and affect the quality of the food stored in it.When this situation continues for a long time, the compressor cannot maintain a low internal temperature. This undermines its operational efficiency. In addition, the longer the door is opened, the hotter the inside of the refrigerator will become.   Because it is very important to keep the door closed, a constant force spring is added to the refrigerator door. If you open them, they will close automatically.A constant force spring is added, which pulls the door back and seals it tightly to the frame when the door is opened. Constant force springs are often the best spring type for this application and can be manipulated in a number of ways to ensure your design works. Constant force springs are characterized by a...
