Application of constant torque spring in wireless radio

Тиме:2022-9-14

With the increasing attention of human beings to environmental issues in the process of social progress, green and low-carbon has become a popular new trend, and energy-saving and environmental protection technologies and products continue to emerge, which are affecting and changing our lives. Hand power generation is a green way of energy supply. The generator powered by the radio contains a constant torque spring motor. When tightening the spring, the spring is gradually wound onto the larger drum, and the mechanical energy obtained during winding is converted into potential energy and stored in the spring. When the spring is released, the stored energy passes through the gear transmission device and the rotating motor to generate output voltage, which is then adjusted by the zener diode to supply power to the radio in the form of a plug.   Constant torque spring motor is a prestressed spring material belt, which forms a coil and is stored on a small storage drum. Then fix the free end and wind it back to the larger output drum; This is the "winding" part of the constant torque spring cycle. When the output drum is released, the spring will return to the storage drum to present its natural curvature, rotating the output drum and providing almost constant torque. When the spring is coiled around a smaller storage drum, a constant torque spring motor is formed. The terminal is then rewound and secured to a larger output drum. The spring part on the output drum is called the "winding part", and you can assemble the spring into a single or multiple configurations.The function...

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...

How to make the constant force spring produce more force

Тиме:2022-9-15

A common way to install a constant force spring is to use two or more springs to obtain greater force in a narrow space. This may be necessary if the diameter or width of a single spring exceeds the allocated space, but there is room to add multiple smaller springs. When engaging multiple springs, a much smaller spring design can be used. The total force is the sum of the spring forces.       When combining springs, it is recommended to use the same spring for multiple installation. Compared with using two or more completely different springs to realize the load, this method is more economical and the design will be simpler. Since the force is the sum of the springs, the total force required should be evenly distributed between the number of springs used. We will discuss three different mounting methods for use with multiple springs.         1、 Back to back method The back-to-back method uses two springs that expand in opposite directions and produce a very stable extension. The distance between the springs should be far enough to allow the spring material to bend naturally so that the component will not bind when retracted.         2、 Series method When two or more springs are used, it is also a very common practice to install springs in series. Although this method does not have the stability of the back-to-back method, space availability usually determines the use of this design. 3、 Laminar flow method Laminating springs together is the third option in this series. The term...

Application of Power Spring in Gas Station

Тиме:2022-9-14

The gas station is a familiar place for everyone. Do you find that the lines of the gas gun are all exposed when passing through the gas station or entering the gas station to refuel? They look messy and unsafe. The car needs to refuel, so you have to go to the gas station to refuel. With the continuous growth of car owners, the passenger flow of gas stations is also increasing. Have you seen the news of the gas station explosion? After a car in a gas station was refueled, due to the negligence of the Refueller, the Refueller did not take out the refuelling gun from the fuel tank port, and the driver of the owner did not check the surrounding conditions of the car, so he started the car. Then the car drove the refueling gun and oil line, pulled down the refueling end connected with it, and caused an explosion. This kind of news is very sad. Once an explosion accident occurs in the gas station, it may cause the explosion of the whole oil tank in the station. Its power is very huge, and the personnel in a certain range around may be seriously threatened. It is understood that the lines of gas guns in foreign gas stations use money collection devices. Now there are a small number of applications in China. At present, there is no large-scale application in gas stations. It uses the characteristics of winding up. It can bring a free contraction process to the line group, and make its winding easier...

Abdominal health wheel is a small pusher that can exercise muscles, joints and reduce weight. The material is generally high-quality engineering plastic, with simple design, beautiful appearance, firmness and durability, and easy to use. It is used to exercise the fat of abdomen, waist, hip, arm and other parts of the body. Due to the simple site required for exercise, it is convenient for home use. The abdominal health wheel with power springs can make people easily complete the recovery movement under the retraction elastic force of the power springs when people use it for exercise and when the body is straightened. As we all know, the characteristic of the power springs are made of steel strip. In use, a spring box is required to limit its outer diameter. The center of the spring is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store the torque. When the external force disappears, the spring will produce the torque on the shaft or spring box. Power springs are often used in products of automatic rewind devices.      The handle rod of the abdominal health wheel is rotationally connected with the wheel body through a bearing, and the handle rods on both sides of the wheel body are provided with power springs. The handle rod passes through the center of the power spring, the inner end of the power spring is connected with the handle rod, and the outer end of the power spring is connected with the side of the wheel body. The handle rod...

[Qianye precision]Constant force spring design in 8 steps

Тиме:2022-9-15

 The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force. However, when our goal is achieved, it can return to the starting point specified by us after displacement. Constant force spring has the characteristic of maintaining constant force in long stroke, and can be applied to products requiring linear movement such as round-trip, sliding, stretching, homing, balancing or labor-saving. For example, we go to the common fan lifting, store display shelves, tape measure, lifting doors and windows and computer monitor lifting. So if you choose a constant force spring suitable for your product, the design has the following 8 steps. 1. Material selection - most flat steel springs produced by Qianye precision are made of type 301 stainless steel. This material is the most readily available and predictable. Thousands of industry engineers can assist in selecting standard sizes to speed up the process. 2. Estimated life cycle - the life of constant force spring is very predictable, making it one of the most important considerations. Being realistic is important because it is estimated that a longer life cycle will lead to larger and more expensive designs. Underestimating the life cycle of constant force springs may lead to premature failure. Common life cycles range from 4000 to about 25000 life cycles. If a longer life cycle is required, the tolerance of increasing spring diameter and force due to low stress levels and small differences in materials...

Transmission hoses and wires are necessary for automotive production and maintenance work, but they are time-consuming and labor-intensive to sort out after use. Another common problem is safety when handling them. This can cause serious injury if the operator is inexperienced. Bulky and unwieldy hoses are also an added risk, especially if they are too short for the job. This forces the operator to move into dangerous positions that can cause injury.   The hose reel now solves these problems by incorporating the maneuverability of the power spring, allowing the long hose to automatically retract after use and align itself continuously and neatly when retracted. In addition, considering the limitations of floor layout and staffing, the hose reel with the addition of the scrolling bar can make full use of space and improve the workplace environment. After use, the hose or wire is retracted to the winder for storage, and generally will not break, and low friction, which can extend the service life of the hose or wire. The tension on the power spring is pre-loaded at the factory, and springs produced by improperly selected manufacturers may become untensioned or over-tensioned. Too much tension can lead to fast and violent retraction as well as a short life span, and the elasticity can fail quickly.   Therefore, it is recommended that manufacturers of hose reels look for high-quality spring manufacturers, because the current reel winding function of the emergence of a deep expansion of the advertising market, so that more electrical products are constantly in the upgrade to create new product selling points. Choosing the right...

Supermarkets and convenience stores can be seen everywhere in the streets and alleys. More and more people are developing retail sales. Businesses will think of the question "How can we overcome each other and stand out in the competition of peers". If you want to stand out from the peers, innovation is indispensable. Now many large shopping malls will install shelf pushers on the shelves, which is not only convenient for customers but also convenient for tally staff, killing two birds with one stone. According to tests, the installation of automatic rack pushers can increase turnover and save labor. Traditionally, the products on the shelves are usually placed in order. When a customer buys the product, it is difficult for the customer to see the product at the back. And install the automatic propeller, after the customer buys the product, the propeller will automatically advance the product in the back, when the customer wants to find the product, it is easier to see, which is convenient for the customer to find the product they want, stimulating Customers' desire to buy. It is the variable force spring that makes the propeller move. When the product is not loaded or the variable force spring is pulled; the variable force spring is statically staying at the front end. When we put on the product or pull the variable force spring, the variable force spring will expand into a straight line. When the variable force spring is unfolded, the variable force spring has a recovery function: it can provide us with the function of naturally restoring...
