Product Description

Power spring

Feature:
The power spring is coiled from 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-stressed power spring can store 25% to 55% more torque and provide more effective turns.




 

The effect of power springs on the retractable dog leash

The quality of leash products on the market is uneven. The power spring is an important link in the quality of the retractable dog leash. There are some problems in the products on the market at present,
 
1. Spring material problem.
The material of the spring is uneven, most manufacturers use ordinary carbon steel material. This kind of spring has poor toughness, uneven thickness and unstable hardness. The retractable dog leash made of such material can not get good user experience in quality, which makes the spring easy to fracture, resulting in the rope stuck, the rope can not be taken back, the rope is broken and the lock key fails.

2. Spring stability problem. 
If the spring strength is too large, it will be recycled too fast. If the hook falls off in case, the recovered hook will be very powerful and hit back, which is easy to hit people and cause injury. At the same time the service life of the spring is relatively short, some only a few thousand times on the failure.
 
In view of such problems, our company has made product updates on the technology of power spring. First of all, our company uses 301 stainless steel material with high precision and high hardness. Its thickness tolerance is controlled in the range of 0.01mm, and its hardness is HV580 degrees, which greatly improves the quality stability of spring products and meets the different needs of different customers for products.
 
In addition, our spring forming process is different from the traditional spring machine. Our self-developed stretch forming process (patented) can greatly extend the service life of the retractable dog leash, reaching 30,000 to 100,000 times. Its expansion speed can be adjusted according to customer requirements. Therefore, the retractable dog leash can be safely and freely retractable, so that you can enjoy the state of walking the dog at any time and anywhere!
 



Notice:
Because this type of spring is a non-standard product, the same shape has different sizes. QianYe has specialized in research and development and production of constant force springs for 20 years, and can customize constant force springs with a thickness of 0.075mm-0.85mm and a width of 4mm-50mm.You can also provide drawings or data (the thickness of the spring, width, working length, inner diameter, outer diameter), and the customer service staff can provide you with a quotation and customized cycle. Welcome to consult.
