A rolling shutter self-opening system

Abstract

The invention discloses an automatic opening system of a roller blind and belongs to a roller blind cloth tool. The automatic opening system comprises a tube, end covers, an automatic roller blind winding device, a linkage mechanism and a locking switch, wherein the automatic roller blind is arranged in the tube and used for automatically winding roller blind cloth; the linkage mechanism is arranged in the tube and used for resisting the binding force of the automatic roller blind winding device so as to automatically open the roller blind cloth; the locking switch is mounted between a roller blind cloth transverse rod at the outer end of the roller blind cloth and the tube and used for locking or unlocking the roller blind cloth transverse rod. The automatic opening system has the advantages that the automatic opening system is reasonable in structure, convenient to mount and operate, economic, practical, small in occupied mounting space, capable of achieving one-button opening through the locking switch, and quite convenient to operate; in addition, a damaged system part can be replaced independently, resource recycling is achieved, and the opening effect of the automatic opening system of a pure mechanical structure can compare favorably with that of electric equipment.

Description

technical field [0001] The invention relates to a curtain appliance, in particular to a rolling blind self-opening system. Background technique [0002] As the temperature rises, indoor glass windows or floor-to-ceiling glass mainly rely on the installation of curtains for shading, shading, heat insulation, and UV protection. This curtain structure is not only time-consuming and labor-intensive to install, but also inconvenient to operate. For sunshade, shading, heat insulation, UV protection, one-way light transmission, and polarized light, some high-end cars will set up electric sunshade curtains on the inside of the side windshield and rear windshield, which can play a role in privacy and protection to a certain extent. Part of the cortex is not burnt, but because of the electric drive, the cost of configuring the electric sunshade is relatively high, some economical cars cannot be equipped with these functions, and because it occupies a large installation space, the fron...
