Characteristic:

The power spring is coiled by steel strip. A spring box is required to limit its outer diameter. The center of the spring is connected to the shaft. When an external force is applied to make the shaft and the spring rotate relative to each other, the spring will be wound on the shaft and stored Torsion, when the external force disappears, the spring generates torsion on the shaft or spring box.

Advantage:

Power springs are divided into natural power springs and pre-stressed power springs according to their relaxed shape. In contrast, the pre-force type power spring can store 25% to 55% more torque and provide more effective turns.

Product manufacturing range:

The thickness is 0.05~0.85mm, and the width is 2.0~60mm.

Principle of the scene:

The high-precision pen injector uses a unique power spring to provide small and highly accurate drug dosages. A fixed amount of medicine is injected into the body through the constant force of the spring and the return speed. The thrust distribution of the steel belt spring accurately matches the sliding force of the traditional syringe, which solves the problem of the dispersion tolerance of the syringe, and provides a high thrust requirement for a highly viscous solution.

Power springs can be used in clockwork toys, timers, and automatic rewinding devices, such as power cords, dog leashes, hose reels, and automatic retraction devices for car seat belts.

Power springs are also widely used in automobile engineering to enhance the safety and convenience of passengers. The seat belts of the car seats are also equipped with power springs. The tension and automatic rewinding functions of the power springs allow each passenger to adjust the seat belt at will. length.

The power spring has a retractable function and is an ideal part of the gravity dissipator applied to the dropper. The anti-falling system is connected between the fixed points of the cable harness, and they can stop the user from falling in the first time. Even when the power spring is fully deployed, the gravity dissipator of the dropper can prevent the user from being hit in the event of a fall.
