Description

Technical Field

[0001] The utility model relates to the field of roller blinds, in particular to a roller blind for retracting and unfolding roller blinds. Background Art

[0002] Roller blinds are made by processing curtain fabric with resin, rolling it into a roller shape, and using a rope or chain to raise and lower it. They mainly include electric roller blinds, bead roller blinds, spring roller blinds, etc.

[0003] There are many kinds of rolling shutters. The awnings used to block rain and snow at the door of shops are also a kind of rolling shutters. The extension and retraction of the awnings are controlled by a rocker. When the awning is extended, it is easier to shake the rocker because of the assistance of the folding rod. However, when rolling up the rolling shutter awning, the folding rod needs to be compressed first and then rolled up, which is more laborious. In addition, the roller of the rolling shutter is relatively thin, which also affects the control of the rolling shutter. Therefore, the inventor invented a roller shutter device for retracting and extending the roller shutter to solve the control problem of the roller shutter device. Utility Model Content
