Corner synchronous coupler of outer sun-shading roller shutter window

Abstract

The invention relates to a corner synchronous coupler of an outer sun-shading roller shutter window, which comprises a connecting-fixing plates fixedly installed at intervals. A transmission head fixing plate is installed on each connecting-fixing plate through fixed bolts, a transmission shaft is installed in each transmission head fixing plate through a clamp spring in a rotating mode, a universal coupler is installed at the tail portion of each transmission shaft through a pin shaft, and two ends of a connecting shaft are installed on the corresponding universal coupler through pin shafts.By means of the corner synchronous coupler, expenditures of a motor of one of windows and corresponding accessories can be saved, and the installation is convenient, and the production and installation costs are reduced effectively. Compared with the prior art, one-key synchronous lifting of the corner roller shutter window can be achieved without complicated modification of circuits and electrical appliances. An angle between two connecting-fixing plates can be adjusted freely according to a wall corner angle of greater than or equal to 90 degrees, and no hinder is caused due to non-right-angled wall corners.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an angle synchronous shaft coupling of an outer sunshade roller shutter. Background technique [0002] During the installation of the external sunshade roller shutters, if a corner window needs to be lifted and lowered synchronously, with the current technical level, only two motors can be used to drive the two outer sunshade rollers respectively, and if it needs to be lifted and lowered synchronously , it must be through complex electrical transformation to realize the one-button synchronous lifting of corner roller shutters. The installation is complicated and relatively high in cost, and future maintenance and repairs will also increase a certain amount of cost accordingly. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a rotary angle synchronous coupling for external sunshade roller shutters with reliab...
