QY Spring Mechanism VS The Traditional Wire Spring Mechanism

In many corded blinds, a switch control is fitted to the side of the track above the blinds, which holds the chain (or drawstring). However, the chains can be dangerous for children. Many countries are gradually banning the use of corded blinds in buildings. Therefore, cordless blinds are now a popular product.

The control system of many manual cordless blinds on the market is a wire spring mechanism, which has the disadvantages of not being able to hover at will, complex components, high costs and large size. Secondly, when it is used for a long time, it will fail to retract and be fixed in a fully open condition state, requiring occasional commissioning. In addition, when the blinds size is particularly small or large, the wire spring mechanism can not be applied, there are limitations.

In response to these drawbacks, Qianye Precision has developed a manual cordless blinds spring mechanism that allows the cordless blinds to hover precisely and arbitrarily. There are no internal elastic elements that fatigue and cannot be kept fully open. There is no restriction on the height and width of the spring assembly and it moves freely up and down to within 2mm. At the same time, according to the matching of different grammage of blinds to achieve the same effect, the assembly for different grammage of roller blinds to make a step change in tension specifications for adaptation, thus greatly improving the scope of application of the device.
