Problems solved by technology

However, when the curtain reel is rotated and the curtain is rolled back on the reel, it must be rotated together with the runner. Due to structural limitations, the diameter of the pull cord runner is relatively large, and the volume of the reel driving device is limited by the operating environment. The restriction cannot be very large, so that the pull rope runner cannot hide a very long rope, and when the curtain reel rotates, it will inevitably be affected by the resistance of the runner that rotates with it, which affects the smooth rotation sex

Abstract

A roll drive device used for reel curtains is provided, which is characterized in that: the invention comprises a rope winding disk case fixed on a curtain bracket, a rope winding disk rotatablely arranged inside the rope winding disk case and wound with a pull rope, a curtain roll rotatablely arranged on a roll shaft in the rope winding disk case, and a one-way clutching device positioned between the curtain roll and the rope winding disk; a back-reel spring is provided between the rope winding disk and the rope winding disk case. Compared with the prior art, the invention has the advantagesthat: the rope winding pulley is able to wind more ropes, the curtain roll is not influenced by pulling rope during reeling, and simple structure.

Description

Technical field: [0001] The invention relates to a driving device for curtains. Background technique: [0002] The existing roller blind reel driving device is all manipulated by an endless bead chain (stay cord) to realize the opening or rewinding of the roller blind. But because the bead chain (stay rope) is ring-shaped, a U-shaped rope loop is formed when the bead chain (stay rope) hangs in the air. When children play near the U-shaped rope circle, the child hangs the neck to the rope circle. Accidental deaths happen here and there. Therefore, its safety, especially for small children, is insufficient. In order to solve this problem, as disclosed in patent application 200610132312.3, the inventor has designed this patent application technology to solve the above problems. It consists of a rotating shaft that drives the reel to rotate, and a pull rope runner that is connected to the runner. A spring groove is arranged on the pull rope runner. On the pull rope runner, t...
