Problems solved by technology

[0002] The control of vertical blinds generally involves blade rotation, opening and closing. Currently, the vertical blind control mechanism in the market is generally controlled by two pull ropes, one of which controls the rotation of the blades, and the other controls the two actions of opening and closing, which is easy for people Confusion occurs, and errors are prone to occur during operation. For this reason, it is necessary to invent a device that can control both the rotation of the blades and the opening and closing of the blades
[0003] Disadvantages of the existing technology: the rotation, opening and closing of the blades are controlled separately, and errors are prone to occur during operation

Abstract

The invention relates to a vertical blind opening and closing device comprises an end cover (1), a rail (2), a belt (3), a plurality of sliding units and transmission mechanisms. The device can be used for controlling blades to rotate, open and close.

Description

technical field [0001] The invention relates to a vertical curtain opening and closing device. Background technique [0002] The control of vertical curtains generally includes two situations, such as blade rotation and opening and closing. At present, the vertical curtain control mechanism in the market generally adopts two ropes to control, one of which controls the rotation of the blade, and the other controls the two actions of opening and closing. Confusion occurs, and errors are prone to occur during operation. Therefore, it is necessary to invent a device that can control both the rotation of the blade and the opening and closing of the blade. [0003] Disadvantages of the prior art: the rotation, opening and closing of the blades are controlled separately, and errors are prone to occur during operation. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new vertical curtain opening ...
