Problems solved by technology

This kind of roller blind, no matter which position the roller blind is opened (rolled), it is necessary to touch the rebound mechanism, and stop the rebound of the rebound mechanism by touching the stop mechanism in the rebound mechanism, so that the roller blind stops at the set position. Moreover, when the rebound mechanism is triggered, the roller blind needs to be rolled back for a certain and uncertain distance due to the stop structure of the rebound mechanism, which leads to the inaccurate release length of the roller blind, which is very uncomfortable to use. convenient

Abstract

A resistance device is characterized by comprising a screw rod with a connecting part, a pipe sleeve rotatably arranged in the connecting part in a sleeving mode, a friction piece arranged on the connecting part and located in front of the pressing end of the pipe sleeve, a nut connected on the screw rod in a screwed mode and springs connected on the screw rod in a penetrating mode and located between the nut and the friction piece. Compared with the prior art, the resistance device has the advantages that release and rewinding of a roller shutter is convenient, and the length of the roller shutter releasing a curtain is controllable and precise.

Description

[0001] Technical field: [0002] The invention relates to a curtain technology. [0003] Background technique: [0004] Some existing curtain technologies require a resistance device whose resistance increases with the increase of the kinetic energy of the curtain to slow down the movement of the curtain or even stop the movement of the curtain. And, because there is no resistance device to counteract the resilience of the rebound mechanism, the rebound mechanism must be provided with a touch mechanism. When in use, the curtain is pulled to release the curtain from the reel so that the curtain can be opened. At the same time, the rebound mechanism stores rebound kinetic energy. Once the curtain needs to be rolled back on the reel shaft, the rebound mechanism is touched, and the rebound mechanism is driven by the power of the rebound energy storage to rewind the curtain back on the reel shaft. This kind of roller blind, no matter which position the roller blind is opened (rolle...
