Description

A plug-in for built-in roller shutters

technical field

The utility model relates to a built-in roller shutter component, in particular to a plug-in for a built-in roller shutter.

Background technique

With the continuous development of building energy conservation, insulating glass windows have been widely used because of their good heat insulation, sound insulation, and anti-condensation. At the same time, for privacy and shading, people need to match the glass windows with curtains. Traditional curtains have problems of space occupation and post-cleaning. In order to solve this problem, people have designed blinds, organ curtains and other sunshade curtains in the hollow glass.

However, in the actual use process, hollow glass windows with built-in sunshade curtains often encounter problems such as the failure of the sunshade curtain to lift, the derailment of the curtain, and light leakage. Due to the built-in design of the sunshade curtain, it is very inconvenient to maintain later. Even professional maintenance personnel need to disassemble the windows with difficulty, so the later maintenance costs are high, which is one of the reasons why built-in sunshade windows cannot be commonly used in residential houses. In order to improve the service life and avoid the above problems, the ideal way is to simplify the structure, integrate functions, improve the firmness of assembly and reduce the wear and tear of components.

Utility model content

The purpose of the utility model is to provide a plug-in for a built-in roller blind that has a firm connection and a compact structure and can be used as a part of a roller blind device.

The technical solution to achieve the purpose of the utility model is: the utility model has an end plate; the upper end of the end plate is provided with an upper inserting block that can be plugged with the upper beam, and the lower end of the end plate is provided with a first bottom that can be plugged with the side beam. Insert block; the end plate is provided with a bearing installation groove, the axis of the bearing installation groove is consistent with the extension direction of the upper insert block; two limit blocks are symmetrically arranged on the left and right sides of the end plate; the limit block is located on the bearing installation Between the groove and the first lower inserting block; between the two limiting blocks is formed a channel through which the rolling shade cloth can pass and which can limit the passage of the bottom beam of the rolling blind; the limiting block extends along the extending direction of the upper inserting block.

A second lower insertion block extending along the extension direction of the first lower insertion block is arranged between the two limiting blocks; the second lower insertion block divides the passage into a first passage for the roller blind to pass through, and a first passage for pulling the shutter. The second channel through which the rope passes; the bearing installation groove is located between the upper insert block and the limit block.

Each limiting block is provided with a through hole at the second channel.

At least one rib is provided on the above-mentioned upper inserting block along its extending direction.

Each limiting block is provided with a clamping block extending along the extending direction of the limiting block. This block is mainly used for the fixed installation of the cloth retaining strip.

The left and right sides of the above-mentioned end plate are symmetrically provided with limiting convex plates for supporting the cloth retaining strip and preventing the cloth retaining strip from turning inward; the two limiting convex plates are located on both sides of the bearing installation groove.

The lower end of each limiting block is fixed with a third lower inserting block extending along the extending direction of the first lower inserting block; the third lower inserting block is located between the locking block and the second lower inserting block.

Each limit block is rounded on the side close to the channel.

The utility model has positive effects: (1) The utility model can effectively prevent the bottom beam of the roller blind from passing through the limit block, thereby avoiding the phenomenon of roller blind over-rolling;

(2) The utility model can not only increase the splicing firmness of the window frame through the second lower insert block, but also divide the passage into the first passage and the second passage for restricting the passage of the bottom beam of the roller blind and the passage of the counterweight. channel; thus maximizing the limit capacity of the plug-in;

(3) The through hole of the utility model is used for fixing the pull rope of the roller blind, so that the plug-in becomes a fixed part of the pull rope, so that the function of the plug-in is more integrated;

(4) The utility model can make the plug-in unit more firm in the splicing of the window frame through the convex ribs, and it is not easy to separate;

(5) The utility model can fix the cloth strip directly by assembling through the clamping block, which is different from the blocking sticker used in the prior art in order to shield the scroll; the cloth strip can be integrated with the window frame, so that the window frame better integrity;

(6) The utility model can effectively prevent the inversion of the cloth retaining strip through the limiting convex plate; the integrity of the cloth retaining strip and the window frame is better;

(7) The utility model can further improve the firmness of the plug-in in the splicing of the window frame through the third lower plug-in block;

(8) The utility model can reduce the abrasion of the pull rope and improve the service life through the rounded corner design.
