Problems solved by technology

[0002] Existing single-stay rope reel curtains all use the mechanism positioning device of the steel ball V-shaped groove, but because the working method of this mechanism is to make the curtain go up a certain distance, the steel ball can only go down after breaking away from the V-shaped groove. So you can't close the curtains completely when you close the curtains up and down

Abstract

The invention provides a single-pull-rope curtain driving device. The single-pull-rope curtain driving device is characterized by comprising an enclosure, a single-pull-rope mechanism arranged on the enclosure and provided with an output rotating shaft, a curtain driving shaft which is rotationally arranged on the enclosure, and a clutch connected between the single-pull-rope mechanism and the curtain driving shaft, wherein the clutch comprises an occlusion block and teeth I; the occlusion block is arranged on the curtain driving shaft and moves along the axis of the curtain driving shaft; one end face of the occlusion block is provided with teeth II; the teeth I are arranged on the output rotating shaft of the single-pull-rope mechanism and correspond to the teeth on one end face of the occlusion block. Compared with the prior art, the single-pull-rope curtain driving device has the advantage that a curtain does not need to move upwards for a certain distance and can move downwards.

Description

technical field [0001] The invention relates to a curtain driving mechanism. Background technique [0002] Existing single-stay rope reel curtains all use the mechanism positioning device of the steel ball V-shaped groove, but because the working method of this mechanism is to make the curtain go up a certain distance, the steel ball can only go down after breaking away from the V-shaped groove. Therefore, it is impossible to close the curtain completely when closing the curtain that opens downward. Contents of the invention [0003] It is an object of the present invention to provide a single pull cord curtain drive mechanism that allows the curtain to go down without the need for the curtain to go up a certain distance. [0004] The present invention is achieved in this way, including a casing, a single pull cord mechanism with an output rotating shaft arranged on the casing (as disclosed in patent CN200610132312.3), rotating a curtain drive shaft arranged on the casing...
