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 children to play with ropes. In developed western countries, the use of beaded roller blinds has been banned and cordless curtains are fully used.
There are many complex components in the spring mechanism control part of many cordless roller blinds on the market, such as: deceleration device, damping device, gear device, limit device, etc. Qianye cancels the traditional complex components, and uses professional spring technology to design, it becomes A spring assembly that can stop at will.
Cordless roller blinds can balance the roller blinds at any position under the action of the spring components according to the height of the roller blinds, and achieve the purpose of stopping at any time. At the same time, the same effect can be achieved according to the matching curtains of different weights. The components are different. The gram weight roller blinds are adapted to the specifications of step-type tension changes, thereby greatly improving the application range of the device.
