An electric curtain that can realize double-layer belt linkage and convenient distance adjustment

Abstract

The invention provides an electric curtain that can realize double-layer belt linkage and convenient distance adjustment. The two ends of the main linkage device and the auxiliary linkage device are respectively connected with guide rails, and belts are respectively wound in the transmission boxes at both ends, and the belt of the transmission box at one end Extend from one of the guide rails into the secondary linkage, and wrap around the outside of the third gear, and continue to extend into the main linkage, and mesh with the first gear, and the belt of the transmission box at the other end is from the other The guide rail extends into the main linkage device and is meshed with the second gear for transmission connection. In use, when the overall length of the guide rail needs to be adjusted, the end cover is pressed down so that the transmission groove of the second gear is in phase with the transmission teeth of the first gear. Cooperate to realize the meshing of the first gear and the second gear, so that the first gear and the second gear drive the belt linkage at the same time, so that even after the distance of the guide rail is shortened or extended, the belt will not be too loose and shaken, so there is no need to move the belt The operation of removing, cutting and connecting again.

Description

A kind of electric curtain that can realize double-layer belt linkage and convenient distance adjustment technical field The present invention relates to the technical field of electric curtains, in particular to a kind of electric curtain that can realize double-layer belt linkage to facilitate distance adjustment. Move the curtains. Background technique [0002] With the continuous improvement of the level of science and technology, more and more intelligent home furnishing appears in people's lives. Favored by most people, electric curtains, as one of the representatives of intelligent home, have brought a lot of convenience to people's lives. Existing electric curtain generally adopts drive motor to drive the transmission belt inside the track, thereby driving the boom and the hoist. The wheel slides in the guide rail to realize the opening and closing of the curtain. This kind of transmission system, which is driven by the transmission belt to open and close the c...

AI Technical Summary

Problems solved by technology

[0003] Existing electric curtains generally use a driving motor to drive the transmission belt inside the track, thereby driving the boom and the suspension wheel to slide in the guide rail to realize the opening and closing of the curtain. Its transmission relationship is relatively complicated, and the process of installing the belt and guide rail is also relatively complicated; the length of the belt is determined according to the length of the guide rail and is not adjustable. Therefore, it is necessary to determine the width of the curtain before determining the length of the guide rail. The length of the drive belt, and once the length is determined, it cannot be changed in the later stage. When the length of the curtain rail needs to be adjusted in the later stage, the belt needs to be cut. Therefore, the traditional electric curtain structure is thicker overall, and the traditional belt drive structure is difficult for installation. unfavorable to late adjustment
