technical field

The utility model relates to a rolling shutter window, in particular to a built-in rolling shutter window.

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.
