Foldable pneumatic single-direction rolling-shaft limiting curtain support

Abstract

The invention discloses a foldable pneumatic single-direction rolling-shaft limiting curtain support. The foldable pneumatic single-direction rolling-shaft limiting curtain support comprises grooved rails, hooks and a drive mechanism, and is characterized in that each grooved rail is of a hollow structure, the drive mechanism comprises an air pump with an inflating and air suction function and a plurality of movable supports which are arranged in the grooved rails, an elastic corrugated pipe is respectively arranged between every two adjacent movable supports, the movable support between every two adjacent elastic corrugated pipes is respectively provided with an air supply passage for communicating the two adjacent elastic corrugated pipes, all elastic corrugated pipes and the air supply passages are fixed and communicated to form a telescopic air cavity with one closed end, the other end of the telescopic air cavity is communicated with an air pump, the upper end of each hook is connected with the lower end of the movable support, and the lower end of each hook extends out of the grooved rails. The foldable pneumatic single-direction rolling-shaft limiting curtain support is stable, reliable, simple in structure and low in installation cost.

Description

technical field [0001] The invention relates to the technical field of curtains, in particular to a pneumatic curtain support structure. Background technique [0002] At present, the more conventional curtain structure is to set a chute on the upper edge of the window, and a plurality of hooks are slidably fitted in the chute, and the buckles on the curtain body are hung on the respective corresponding hooks in sequence, thus by catching Hold the curtain body, and swing the curtain body to realize the opening and closing of the curtain, but the force exerted by the above-mentioned man grasping the curtain is not only the force used to open and close the curtain in the horizontal direction, but also the force to pull the curtain downward, so it needs to be applied by personnel. Large force, which not only causes inconvenience to opening and closing the curtain, but also causes damage to the buckle and hook on the upper end of the curtain after excessive pulling force or long-...

AI Technical Summary

Problems solved by technology

[0002] At present, the more conventional curtain structure is to set a chute on the upper edge of the window, and a plurality of hooks are slidably fitted in the chute, and the buckles on the curtain body are hung on the respective corresponding hooks in sequence, thus by catching Hold the curtain body, and swing the curtain body to realize the opening and closing of the curtain, but the force exerted by the above-mentioned man grasping the curtain is not only the force used to open and close the curtain in the horizontal direction, but also the force to pull the curtain downward, so it needs to be applied by personnel. Large force, which not only causes inconvenience to open and close the curtain, but also causes damage to the buckle and hook on the upper end of the curtain after excessive pulling force or long-term use

[0003] In the prior art, although there are some automated curtains in which the motor drives the cable and finally directly drives the hook to slide, the process of the above-mentioned motor driving the cable not only has the risk of the cable breaking or the connection end being disengaged, but also the cable stretching. Both the cable channel and the storage mechanism are required during the storage and storage process, which further increases the structural complexity and increases the installation cost
