When taking the high-speed railway, everyone should like to look at the scenery outside the window. I don’t know if you have paid attention to the curtains on the bullet train. When I take the bullet train, I often find that there is no buckle on the curtain slide rail on the bullet train, but I can still go up and down freely and won’t fall or bounce back. That is to say, when I pull down 1 / 3, it will stop at 1 / 3, and when I pull down half, it will stop at half; If you want to put it away, just push it up and stop where you push it? It’s different from the curtains I usually see at home. Isn’t it affected by gravity?
With this curiosity, let me show you that the bullet train should be a spring roller shutter. The elasticity of the spring roller shutter can adjust the rise and fall of the fabric within a certain range and can stop at any position. Gently pull down and let go. The fabric can bounce back to the top of the curtain leisurely and freely. The operation is light, the operation time is short, and the stay position is arbitrary. Compact structure, flexible and convenient operation.
Because the addition of variable force spring makes the roller shutter achieve this effect, many variable force springs on the market can not achieve the effect that the force is changing in any section, so many electric roller blinds will add some components (deceleration device, damping device, this wheel device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause.
Compared with the ordinary electric curtain system on the market, our advantages are as follows:
1. Service life: the service life is greatly increased and the attenuation degree of force value is less than 10%.
2. Convenience: simple structure and high stability.
3. Technology: there are no restrictions on height and width.
Qianye precision often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which has solved the problems and pain points in the traditional use of lifting system, and better solved the problems of free positioning and free pause in the traditional lifting system.

In order to conform to the height of ergonomics, adjustable desk and display bracket have been widely used in the market. These applications enable people to choose to work sitting or standing, and adjust the appropriate height of equipment to meet the needs of medical care. The application of these two products can not be separated from the constant force spring....
I'm sure many of you know what a constant force spring is, right? A constant force spring is a spring that maintains a constant spring force for a specific stroke, also called a constant force spring, and is used in a linear motion, usually using its rebound force. A constant force spring consists of a spiral-shaped metal sheet that is bent on the inside so that...
Timer is a precise timing device, which uses mechanical clock to drive the switch. Its time positioning is very accurate, and it can achieve such effect. Spring plays a great role in it. The emergence of timers has brought great changes to our lives. At first, we used the hourglass to determine the time. In modern life, timers have been...
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 pre-stressed...
Spring has been very common in people's daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children's stationery for school. It can be seen how important spring is to our life. What is the definition of spring? It is a mechanical part that uses elasticity to work. Generally made of...
Power springs are a variation of coil springs that provide high force output with minimal force requirements. Power springs are sometimes called clock springs because they are often used to power certain types of clocks. Power springs are capable of high force output with very small space requirements and, when extended, store power indefinitely. This allows power springs to be...
