Abstract

The invention relates to a torsion assisting component for use in a roll curtain that provides torsion assisting force to automatically retract a curtain cloth in a shielding curtain to the interior of a roll curtain shaft pipe. The torsion assisting component includes a torsion coupling member and a torsion spring; the torsion spring is hooked into a long hole of the torsion coupling member through a "[" -shaped hooking pin at one end thereof; the torsion coupling member further forms a check hook in the long hole, and the check hook can block and limit the "["-shaped hooking pin, so that the"["-shaped hooking pin of the torsion spring penetrates through and is hooked with the long hole of the torsion coupling member so as to prevent loosening, and in this way, the stability of a combination between the torsion spring and the torsion coupling membercan be increased.

Description

technical field [0001] The invention relates to a torsion booster assembly used in a roll-up shade to provide torsion boost so that the curtains in the shade can be automatically rolled up to the inside of the shaft tube of the roll shade. Background technique [0002] The existing roll-up blind is mainly to connect one side of the curtain to a shaft, and then install the curtain and the connected shaft together in the shaft tube, so that the curtain can pass through the long hole on one side of the shaft tube. It stretches out and can be retracted into the shaft tube. In order to enable the curtain to have the function of automatically retracting and pulling, the existing roll-up shade is also equipped with a torsion assist component in the shaft tube of the roller shade, so as to provide torsion assistance to the shaft when the curtain is retracted by using the torsion assist component. [0003] In the existing roller blind mechanism, the known torsion power-assisted comp...
