Description

A built-in roller blind device

technical field

The utility model relates to a driving part of a built-in roller blind, in particular to a built-in roller blind device.

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 insulating 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.
