Abstract
The utility model discloses a rolling up structure for curtain. The model is mainly composed of a fixed-position unit, a driving unit, a transmission unit and a turning collar bush. The fixed-position unit is used for holding and providing the driving unit. The driving unit is composed of an anchor tie and a driving disk. The front end of the driving unit is provided with the transmission unit. Simultaneously, the outer of the transmission unit is sleeved with the turning collar bush. Therefore, the anchor tie is used to drive the driving disk and the driving disk is caused to make the turning collar bush turn through the transmission unit. In this way, the purpose of rolling up the curtain is achieved. A gear ratio is used between the driving disk and the transmission unit to make the turning speed of the transmission unit be slower than the turning speed of the driving unit. In this way, more labor can be saved when the curtain is rolled up.
Description
Technical field
