Factors affecting the rupture of power springs: The power spring is made of stainless steel strip. A spring box is required to limit its outer diameter. The spring center 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. The advantage of power spring is that it can be divided into natural power spring and pre force power spring according to its relaxed shape. In contrast, the preloaded power spring can store 25% to 55% more torque and provide more effective turns. Power springs are mainly used in products such as clockwork toys, timers and automatic rewinding devices (such as power cord, dog puller, pipe winder and automobile safety belt) It is often seen that the scroll spring purchased will break soon after it...

Pull Bead Roller Blinds and Cordless Roller Blinds: The roller blinds are blackout roller blinds, soft yarn roller blinds, and Shangri-La roller blinds in appearance. They are mainly corded and cordless. Roller shutters have many advantages such as beautiful and simple appearance, firm and durable structure, etc. Roller shutters are suitable for various places, especially for large-area glass curtain walls. When the roller blind fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good shading effect. When the roller blind is raised, its volume is very small, so that it is not easy to be detected. The bead roller blinds use the rope or chain to ascend and descend. The biggest problem of the rope/bead system is that the curtain will not be pulled when it is too big, and the rope will easily break. It is not very convenient to use, and the rope is easy to get dirty. It is very dangerous for children to play with ropes. In developed western countries, the use of beaded roller blinds has been banned and cordless curtains are fully used. There are many complex components in the spring mechanism control part of many cordless roller blinds on the market, such as: deceleration device, damping device, gear device, limit device, etc. Qianye cancels the traditional complex components, and uses professional spring technology to design, it becomes A spring assembly that can stop at will. Cordless roller blinds can balance the roller blinds at any position under the action of the spring...

Do you know the principle of medical cart?: During the normal operation of the hospital, it is often necessary to use the medical cart. The medical cart refers to the ward protection and transfer of medical equipment. The medical cart prevents the patient from causing further injury in the process of transporting the patient. At the same time, it also reduces the labor intensity of medical staff or family members. It is a commonly used medical device. At present, the medical cart on the market can only be used in the process of lifting the patient from the hospital bed to the cart or from the cart to the hospital bed, The scope of use is narrow, which is easy to cause a waste of resources and the problem of single function. Therefore, a medical multifunctional cart is proposed to solve the above problems. The medical multifunctional cart has simple structure and convenient operation. It can be used as a medical cart under normal working conditions.

The new computer monitor spring design offers greater durability and flexibility: Computer monitors are an essential component of any modern computing system. They allow us to see and interact with the graphical user interface that enables us to use our computers for a wide range of applications, from word processing and data analysis to gaming and entertainment. Over the years, computer monitors have undergone significant improvements in design and functionality, leading to the development of high-resolution displays, curved screens, and other features that enhance the user experience. One area where monitors have often fallen short, however, is in their durability and flexibility. Many users have experienced problems with cracked screens, broken hinges, and other hardware issues that can render their monitors unusable. To address this problem, a new spring design has been developed that offers greater durability and flexibility. The new design is based on a series of interlocking springs that are integrated into the frame of the monitor. These springs are designed to provide a level of flexibility that allows the monitor to bend and twist without breaking, while also providing a high degree of durability that makes it resistant to damage from impacts and other forms of wear and tear. The result is a monitor that can withstand a wide range of environmental conditions, from extreme temperatures to high humidity, and is less likely to suffer from the types of hardware problems that can plague traditional monitors. One of the key advantages of the new spring design is its ability to absorb shock and vibration. This is particularly important in applications where the monitor may be...

Constant force spring for realizing smooth movement of CT scanning table: We are familiar with CT scanner. Now when we go to the hospital for examination, we often hear the doctor say "take a film first". This film generally refers to CT. Doing CT is not only for the safety of patients, but also for the safety of doctors. CT is much clearer than X-ray film. At the same time, there are many diseases that cannot be seen on B-ultrasound and can be diagnosed by CT. At present, CT is the most widely used imaging examination under medical treatment and the most valuable examination for clinical information. When you go to take CT, you lie down on the scanning table, and the scanning table will automatically move smoothly and accurately locate the position. Have you ever thought about this problem because you want to relieve tension? The CT scanner table can move smoothly and accurately because of the role of the constant force spring in it. Some little friends may not know what the constant force spring is. When it comes to the spring, everyone must think it is the traditional linear spring. In fact, it is not. Constant force spring is made of stainless steel strip. The high-strength steel strip is shaped through specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force, However, to achieve our goal, we can return to our designated starting point after the shift.

Power spring in the design of the car covers: Car covers are commonly used automotive protective articles, but the folding and storage of car covers is a troublesome thing. In order to solve this problem, invention lovers have done a lot of useful exploration and put forward many solutions. One kind of scheme is to use power to drive the reel to directly roll up the car cover cloth. Using the reel to directly roll up the car cover cloth can achieve the purpose of rapid retraction of the car cover, but there are the following problems in actual use: first, the winding and friction of the reel when directly rolling up the car cover cloth wear the car cover cloth greatly; second, in order to adapt to the width of the car cover cloth, the width of the car cover retracting device must be close to the width of the car cover cloth. If it is too narrow, it will increase the winding of the car cover cloth, so the shape of the car cover retracting device is larger, It reduces the convenience of use: Third, it may not be able to completely stow the hood cloth. Only one power spring is needed to solve the above series of problems. The power spring designed by Qianye precision can be applied to the car cover. The power spring retracts the car cover to realize the rapid retraction of the car cover. At the same time, it solves the problems of large wear, large device shape and high operation intensity caused by the direct retraction of the car cover cloth by the reel, as well as the problem...

Constant force spring damper: Dampers are widely used in building structures to dissipate energy and reduce vibration. However, the traditional damper has complex structure, poor durability and corrosion resistance, and low working stability. After using for a period of time, the damper is prone to aging and deformation can not be restored, so it can not be used anymore. Most of the existing dampers use shape memory alloy (SMA), which is a material composed of more than two kinds of metal elements through thermoelasticity, martensitic transformation and its inversion; Using shape memory alloy, the damper can automatically restore to its original shape after deformation, which is used for the restoration of building structures after deformation. However, the existing dampers only use the performance of shape memory alloy (SMA) wire itself, and the cost is expensive, which is not conducive to the large-scale use of dampers. The design of constant force spring can be added to the self resetting damper. The damper includes piston parts, U-shaped plates and moving rods. The constant force spring is set between the tension moving rod and the pressure moving rod. The constant force spring tightens the tension moving rod and the pressure moving rod to be close to each other, so that the tension moving rod and the pressure moving rod respectively lean against the end close to each other in the corresponding sliding hole. It is conducive to the large-scale use of self resetting dampers. Constant force spring is a kind of functional material with high ductility, which has the advantages of constant load, high energy storage density, low friction loss and so on....

Do you know what springs are used as stop mechanisms?: 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 arise. If the spring is pulled tight on the screw, a hump will result that will not only make the retraction difficult but will cause a fracture point and reduce life cycles. To avoid this, we recommend that the spool maintain 1-1/2 wraps of spring material at the furthest extension. If these additional wraps are not practical in the design, another method of stopping the rotation is required. Constant Torque Spring Applications: This type of motor spring is commonly used to retract a cable or to keep a constant torque rotational force on a spool. It is extremely important not...

Application of power spring in draw-wire encoder: A draw-wire encoder, also known as a string potentiometer, pull wire position sensor, cable extension displacement sensor, or yo-yo potentiometer. It is a cable driven position or displacement sensor for linear position measurement and velocity using a flexible cable (wire) and a spring loaded spool. The string pot or cable extension sensor is composed of four main components in the shell: 1. High strength stainless steel cable (rope or steel wire rope); 2. Equal diameter spool (drum); 3. Power spring with high torque and long service life; 4. Rotary potential precision sensor. In the shell of the sensor, a soft high-strength stainless steel cable is tightly wound on a precision machined cylindrical drum (or spool) with constant diameter, which rotates with the winding and unfolding of the measuring cable. In order to maintain the tension and retraction of the steel wire, the spring is connected to the drum. Then connect the spool to the shaft of the rotary potential precision sensor (or encoder). When the sensor string extends linearly with the moving object, it will cause the roller and sensor shaft to rotate. For displacement or position measurement, the main body of the sensor is installed on the fixed surface, and the end of the flexible cable is connected to the moving object. When the object changes its position, the cable unfolds and reels and the rotating spool drive the shaft of the sensing device, generating an electrical signal proportional to the linear extension or displacement of the cable. For speed measurement, a tachometer is required. The power spring is mainly used in the equipment of...
