Roller blind

Abstract

A roller blind comprises a main frame girder, a left fixing seat and a right fixing seat respectively on bilateral sides of the main frame girder, a rotary sealing cap installed on the right fixing seat, a rolling device sleeved on one end of the sealing cap, a control device fixed on the left fixing seat and used for connecting one end of the rolling device, and a curtain capable of being rolled on the rolling device. The control device comprises an outer sleeve body, a rotating unit installed inside one side of the outer sleeve body, a locating rod in shaft connection with the rotating unit and fixed on the left fixing seat, and a connecting seat installed inside the other side of the outer sleeve body and used for sleeving and fixing one end of a shaft rod of the rolling device. The other side of the outer sleeve body is nested on one side of the rolling device. The circumference of the rotating unit having a sleeve is annularly provided with at least one soft cushioning ring which completely contacts with the inner wall of a rotating body. The rotating body can be driven to change the rail with the help of the soft cushion ring, so as to stretch, roll and locate the curtain; meanwhile, the rotation friction of the rotating body as well as the cushion effect of rolling the curtain can be increased.

Description

technical field [0001] The invention relates to rolling blinds, in particular to a soft buffer ring to drive the rotating body to change the track to achieve the stretching, retracting and positioning of the curtain, and to increase the friction resistance of the rotating body and the buffer when the curtain is retracted. Effect. Background technique [0002] There are several types of roller blind structures on the market today, which are mainly installed in homes, office doors and windows, etc., to achieve the functions of shading sunlight and decoration, and have become quite popular. Collapse method, see Figure 1 ~ Figure 3 As shown, the roller blind 1 at least includes a main frame beam 11, a reel set 12, a pull-opening and folding device 13, an oil pressure buffer device 14 and a pair of left and right fixing seats 15, 16, wherein the The opening and closing device 13 provided at the left end of the main frame beam 11, when pulled once, the curtain 17 is unfolded clo...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a rolling blind to improve the above-mentioned existing rolling blind opening and closing device. As a buffer, the blinds will not be rolled up quickly, and the assembly volume is large and the cost is high. The inventor improves on the above problems, and then proposes a roller blind that overcomes the existing shortcomings.
