When the curtain is pulled to the top it sags and when it is pulled to the bottom it springs back a certain height.
Qianye Spring Company has succeeded in developing this cordless blinds spring. The steps in the design of a cordless curtain spring are as follows.
It is usually necessary to determine the weight of the curtain. It is usually possible to measure the force required to hold the cordless curtain at the top and to measure the force required to hold the cordless curtain at the bottom.
It is usually necessary to determine the duration of use of the curtain. For example, a spring with a life of 8,000 strokes will not loosen or deform within the life of the spring.
The space where the spring is to be placed, the distance between the two springs, the outer diameter of the spring, etc. should be taken into account.
This stage is usually the adjustment of the force. For example, increasing the force of the spring at the beginning or decreasing the force of the spring at the end.

The lifting window is different from the traditional internal opening, external opening and ordinary push-pull mode, but adopts the opening mode of lifting up and down. Because it is mainly popular in North America, it is also called American lifting window. It is one of the two major door and window categories in the world. The lifting window is more compact than...
Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while...
The variable force springs can break through the traditional spring affected by Hooke ' s law, so that the stroke and force are no longer proportional to increase, but can achieve a variety of elastic displacement combinations such as negative slope stepped fixed force. According to the needs of mechanical engineering, the relationship between elastic force and displacement stroke can be used...
Seat belts and springs are both important parts of a car. Seat belts keep you safe in case of an accident, while springs keep the car in shape. It's important to know how to use both of these parts properly. What are seat belts and springs, and what do they do? A seat belt is a device used to secure...
Imagine, on the weekend of a busy work week, unloading from work, taking a hot bath, having a leisurely dinner, and when it's time to rest, draw the curtains to isolate the noisy world outside, and then, beautiful and beautiful Sleeping until you wake up naturally, this is not the most important thing for every office worker. However, for...
3D printing, also known as three-dimensional printing, is a kind of rapid prototyping technology. It uses adhesive materials such as powdered metal or plastic to construct zero objects through multi-layer printing layer by layer. Mold making, industrial design is used to build models, and is now developing into product manufacturing, forming "direct digital manufacturing". Some high-value applications (such as hips...
