Electric windproof roller blind

Abstract

The invention discloses an electric windproof roller blind and belongs to the field of electric roller blinds. The electric windproof roller blind comprises a roller blind body, a lower beam, side rails and a reel pipe assembly. The left and right edges of the roller blind body are each provided with a zipper, and zipper guiding rails are arranged in the side rails. Elastic tensioning pieces matched with the side rails are arranged on the zipper guiding rails, and front supporting grooves are formed in the positions, on the front side of the roller blind body, on the side rails. Rear supporting grooves are formed in the rear side of the roller blind body. The elastic tensioning pieces comprise catapults which are provided with front arches matched with the front supporting grooves and reararches matched with the rear supporting grooves. According to the electric windproof roller blind, the zipper guiding rails are arranged in the side rails firstly and can be matched with the zippersof the roller blind body, the roller blind body is pulled towards the two sides through the catapults to prevent the roller blind body from being gathered towards the middle, thus elastic tensioning force can be provided from the two sides of the roller blind body to prevent the roller blind body from being blown, fabric flatness is ensured, the sealing property of the two sides of the roller blind body can be improved, and the shading effect is better.

Description

technical field [0001] The invention is used in the field of electric roller blinds, and in particular relates to an electric windproof roller blind. Background technique [0002] Electric roller blind is a kind of light motorized roller blind developed with tubular motor. Its operation only needs to toggle the power switch. It is easy to operate, quiet and stable in operation. It is an upgraded product of roller blind. In comparison, its performance-price ratio is very superior. Motors of different specifications can be selected according to the size and weight of the curtain, and one motor can be used to drag multiple pairs of roller blinds. In the past, the roller blind mechanism often used the gravity of the drawbar at one end of the roller blind to stretch and fix the roller blind. Folding, and the two sides of this roller blind are not sealed enough, and the shading effect is not good. [0003] In addition, the roller tube assembly of the previous roller blind mecha...

Problems solved by technology

In the past, the roller blind mechanism often used the gravity of the drawbar at one end of the roller blind to stretch and fix the roller blind. Folding, and the two sides of this roller blind are not sealed enough, the shading effect is not good

[0003] In addition, the roller tube assembly of the previous roller blind mechanism is often fixed on the top of the electric roller blind by using threaded fasteners, etc. The disassembly process of the roller tube assembly in this structural form is complicated, the workload is heavy, and it is difficult to ensure the installation. unity
