Problems solved by technology
This kind of roller blind, no matter to which position the roller blind is opened (rolled), it is necessary to touch the rebound mechanism so that the roller blind stops at the set position, and when the rebound mechanism is triggered, it is triggered by the rebound mechanism. Determined by the structure of the device, the roller blind needs to be rolled back for a certain and uncertain distance, resulting in an inaccurate release length of the roller blind, which is very inconvenient to use

Embodiment Construction
[0015] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0016] Such as figure 1 As shown, the present invention includes a bracket d, a reel c with a curtain b rolled on the support d, a resistance device a arranged at one end of the reel c, a return spring e arranged at the other end of the reel c, The spring free end of the rewinding spring e is connected to the reel c through the connector g fixedly connected with the free end of the spring and rotates with the rotation, and the connection end of the rewinding spring e is connected to the bracket d at the other end of the reel c ,Such as figure 2 As shown, the resistor a of one embodiment 1 includes a screw 2 with a cylindrical connecting part 1, a sleeve 3 that is rotatably fitted on the connecting part 1, and is arranged on the connecting part 1 and located on the sleeve 3 to apply pressure. The friction plate 4 in front of the end 3a, the nut 5 screwed...

A roller shutter comprises a support, a rolling drum rotatably arranged on the support and provided with a curtain in a rolling mode, a resistor arranged at one end of the rolling drum and a rollback spring arranged at the other end of the rolling drum. The spring free end of the rollback spring is connected with the rolling drum and rotates along with rotating of the rolling drum, the connecting end of the rollback spring is connected to the support at the other end of the rolling drum, and the resistor comprises a threaded rod with a connecting part, a pipe sleeve rotatably connected to 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 to the threaded rod in a screwed mode and a spring connected to the threaded rod in a penetrated mode and located between the nut and the friction piece; and the connecting part of the resistor is connected to the support of one end of the rolling drum. Compared with the prior art, the roller shutter has the advantages that the roller shutter can be convenient to unroll and roll, and the length of the curtain unrolled by the roller shutter is controllable and accurate.
Description
[0001] Technical field: [0002] The invention relates to a curtain technology. [0003] Background technique: [0004] Existing cordless roller blinds are generally equipped with a rebound mechanism. When in use, the curtain is pulled to release the curtain from the reel to open the curtain. At the same time, the rebound mechanism stores rebound kinetic energy. Once the curtain needs to be rolled back When the rewind shaft is on, the rebound mechanism is touched, and the rebound mechanism, driven by the power of the rebound energy storage, rolls back the curtain on the reel. This kind of roller blind, no matter to which position the roller blind is opened (rolled), it is necessary to touch the rebound mechanism so that the roller blind stops at the set position, and when the rebound mechanism is triggered, it is triggered by the rebound mechanism. Determined by the structure of the device, the roller blind needs to be rolled back for a certain and uncertain distance, resultin...
