Description

Shangri-La curtain capable of preventing lower beam from overturning

Technical Field

The utility model belongs to the technical field of the building sunshade, a Shangri-La curtain is related to, concretely relates to prevent underbeam upset Shangri-La curtain.

Background

Shangri-La curtain is a sunshade screen that has the decorative effect, and this product can be through angle of adjustment when extending completely for the surface fabric can realize from closed to three-dimensional solid, when guaranteeing indoor private space, can let light penetrate into and make indoor bright, and can also keep indoor outer outstanding permeability. The product has the advantages of softness, beauty and conciseness of novel shading products of the traditional window screen, forms a three-dimensional structure when being completely unfolded, can freely adjust indoor light requirements, can be completely rolled, and allows the curtain to be completely transparent.

The common structure of the Shangri-La curtain consists of an upper part (a housing, a rotating shaft, a head making part, a tail plug and a housing sealing cover), a middle part (Shangri-La fabric), a lower part (a lower beam, an anti-collision strip, a balancing block and a lower beam sealing cover), and the basic operation principle is as follows: the system head moves the pipe, rolls up and transfers the surface fabric, when transferring to the low end, rotates through the pipe small-angle, drives Shangri La surface fabric, relies on the underbeam of lower part and the bistable of balancing piece for the surface fabric is or becomes three-dimensional form, or becomes plane, reaches the sunshade of Shangri La curtain, decorative effect.

There are three states of use of the Shangri-La curtain in actual use: open mode, closed state, rolling state, when the Shangri La curtain was rolled up completely, rely on the underbeam to act as the location shelves strip when rolling, fix a position the curtain, will reach such effect, the thickness of underbeam need be greater than the inside space of housing when rolling, if be less than the space, will lead to the underbeam to empty and overturn, damage the structure of curtain, lead to the curtain to scrap.

In order to avoid the phenomenon, the large cover and the small cover need to be selected comprehensively according to the thickness of the fabric and the height of the curtain, so that the large cover and the small cover need to be selected by experienced personnel, or the large cover and the small cover need to be accurately grasped by modern online computing software to select, or unnecessary loss is caused once the selection is wrong. As shown in figure 1, the Shangri-La curtain without the function of preventing the lower beam from overturning has the advantages that the gap distance between the rotating shaft and the housing (the upper cover) after the rotating shaft wraps the fabric is larger, and when the rolling force is larger, the lower beam assembly easily penetrates through the gap to cause overturning.
