AI Technical Summary
Technical Problem
The resetting force distribution of existing torsion spring roller shutters is uneven, which causes the rolling cloth to easily sway when it is pulled or retracted, which in turn causes the rolling cloth to be pulled out or retracted misaligned, affecting normal use.
Method used
The left torsion spring and the right torsion spring are provided in the sleeve so that the resetting force of the torsion spring is distributed at both ends of the sleeve surface, increasing the balance between the roller shutter pulling and winding.
Benefits of technology
Through the evenly distributed resetting force, the roller shutters are pulled out and rolled smoothly on the sleeve, reducing misalignment and extending the service life of the roller shutter assembly.

Abstract
The utility model discloses a roller shutter assembly, a roller shutter device and a protective device, the roller shutter assembly comprises a sleeve, a roller shutter capable of being wound on the periphery of the sleeve, a left torsional spring and a right torsional spring, the left torsional spring and the right torsional spring are arranged in the sleeve, and each of the left torsional spring and the right torsional spring comprises a spiral torsional spring body and a first connecting part and a second connecting part which are arranged at the left end and the right end of the spiral torsional spring body; a mounting part used for connecting the second connecting part of the left torsional spring and the first connecting part of the right torsional spring is arranged in the sleeve, the second connecting part of the left torsional spring and the first connecting part of the right torsional spring are connected to the mounting part, and the first connecting part of the left torsional spring and the second connecting part of the right torsional spring can both extend out of the sleeve; the sleeve is rotatably mounted on the seat body. The reset force of the torsion spring can be distributed at the two ends of the surface of the sleeve, the balance of the roller shutter in the pulling and rolling process is improved, then the roller shutter is pulled out and rolled on the sleeve smoothly, the situation that the roller shutter is dislocated is not prone to occurring, and the service life of the roller shutter assembly is prolonged.
