Abstract

The invention discloses a transmission device of a curtain. The transmission device comprises a frame, a reel pipe, a main spring, a spring shaft, an oil pressure damper, a torsion spring, a positioning set and a curtain cloth set. After curtain cloth of the curtain cloth set is pulled down to an arbitrary height, the reverse rotation of the main spring can be prevented by the positioning set once the application of force is stopped, so as to allow the curtain cloth to stop at the arbitrary height; in addition, no matter at which height the curtain cloth stops, only by pulling down the curtain cloth and releasing the curtain cloth immediately, the positioning set does not prevent the rotation of the main spring any longer, the main spring rotates with the reel pipe, and the curtain cloth rolls up automatically till to be positioned. The transmission device can achieve the aims of stopping the curtain cloth of the curtain at the arbitrary height and easily allowing the curtain cloth to roll up automatically.

Description

technical field [0001] The invention relates to a curtain device, in particular to a transmission device for the curtain. Background technique [0002] Curtains are decorative appliances used in many buildings in today's society. According to the difference of the curtain and its structure, it can be divided into pleated shade, honeycomb shade and Roman shade. Yet no matter be above-mentioned which kind of type, the transmission device of its control curtain cloth is all similar. [0003] Most of the existing curtains are equipped with a pull cord to control the pulling up and down of the curtain. However, when the transmission device pulls up the curtain, the pull cord will also move upward, which may cause accidental injuries such as strangling the human body. Therefore, the new curtains are all improved to the type without pull cord, and the transmission device is also improved. The transmission device is to set a torsion spring in the frame, one end of the torsion sprin...
