  Constant force springs are mechanical devices used in applications that typically require some kind of balance or retraction mechanism. In design and function, constant force springs differ from the more common types of coil springs. They apply a consistent linear force or torque that remains constant over a wide range of motion. When a coil spring is under force, whether it is stretched, compressed, or rotated, it produces a force proportional to its stretch. How a spring responds when a force is applied or released is called spring deflection. Years of experience tell us what happens when a spring is released from its temporary state. We know that the spring will return to its original position, but it will be proportional to the force exerted on it before releasing. A spring has a restoring force that allows the elastic material to return to its original state - the equilibrium position after the applied force is removed. Stretching, squeezing or twisting, what...

There are many mechanical components to choose from for your device or application. If your device requires a spring, consider constant force springs. These are a type of extension spring. They do not obey Hooke’s law, so their force remains constant, even when deflected. Because of their flat force curve, constant force springs are suitable for applications that require a smooth range of motion and a constant load. Learn more about this type of spring to see if it could work in your device or application. Constant Force Spring Benefits There are many benefits of constant force springs that make them suitable for a number of applications: Have small space requirements Provide a smooth range of motion Have no inertia to overcome Mount to existing hardware Produce a counterbalance effect For these reasons, constant force springs are versatile enough to work for a number of applications in which a constant load is required to counterbalance, tension, retract or dispense. This is why they’re frequently used to enhance...

 A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of the belt that is close to the roll. Since the geometry of this region remains nearly constant as the spring unfolds, the resultant force is nearly constant.       By creating a spring with a variable pitch, you can make a push-shape spring with a constant velocity. Placing a larger pitch in a larger outer diameter coil and a smaller pitch in a smaller outer diameter coil will force the single spring to fold all coils at the same rate when compressed.       Design of Constant Force Springs: A constant force spring is a coil of prestressed...

Variable force springs are very common in the point-of-purchase or POP industry, especially in shelf pushers. Variable force springs provide variable force to precisely match increasing or decreasing force requirements, propelling the product horizontally forward. Due to their wide applicability, these springs can be seen in the tobacco, cosmetic, electronics and medical industries. So why use variable force springs in shelf thrusters?       1. Inventory Control        Variable force springs are commonly used in trays that push products forward in a controlled manner. Variable-force springs in the push-in trays aid product fronts, so the shelves are always well-stocked. These trays allow for more organized store inventory and help track inventory needs. This is even more critical in today's COVID-conscious environment.         2. Product Integrity        Variable force springs are designed around the weight of the product they push. This ensures that the product is never slammed or damaged when it is...

ข้อดีของ Qianye Cordless Spring Components

All curtain cords, whether installed on the side, caught in curtains, or placed on the back, can be dangerous to children. It is best to replace all corded curtains with cordless curtains in houses where children live or visit, especially in children's bedrooms and play areas. Cordless roller blinds with either a spring system or an electric system can improve the safety of the home.        Cordless roller blinds with spring system are similar to movie curtains. They use the elasticity of the springs. Under the action of the spring components, the roller blinds can be balanced at any position and can be stopped at any time.        At present, most of the spring components on the market are wire spring cordless curtain systems, which have a relatively short service life and a high degree of force attenuation. When pulling down, the curtain stops at each clip, and when rising, pulling down makes the curtain bounce...

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...

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...

As more and more people spend more and more time using computers, computer users spend more time sitting or standing at their desks or workstations in front of devices. Keeping what experts call "the best ergonomic positioning" can improve energy levels and overall comfort. For this purpose, the input and output devices must be placed in appropriate positions. The proper position can reduce the muscle strain of the user's arm and effectively prevent various musculoskeletal diseases, including carpal tunnel syndrome, neck pain, and upper and lower back pain.   The attachment bracket can be used to facilitate the support and position adjustment of the fixed attachment. The attachment retainer allows simple three-dimensional adjustment of two such devices to place the devices in a more ergonomic relative position to meet the needs of various users and workspaces, and has a balancing mechanism for balancing the weight of fixed attachments.   The balance mechanism provided by the wall mounted accessories is superior to the traditional lifting system,...
