Description

Locking structure of curtain reel

The present invention relates to a locking structure of a curtain reel, in particular to a locking structure of a curtain reel that can securely fix the reel and reel base of the reel without using any tools during the assembly process, and has the convenience of assembly .

Press, installing windows indoors can change the daylighting, increase the brightness of the lighting, and make the air easier to circulate, so that the room is cooler and not stuffy, and the ventilation is better. The installation of windows can also cause the indoors to be peeped by outsiders, and direct sunlight and temperature rise, etc. Disadvantages. Therefore, curtains are usually installed on the inside of windows to adjust the brightness of the light entering the room and prevent outsiders from prying into the room.

In the existing curtains, when the curtain assembly is fixed and combined with the slide rails, screws and other fasteners are generally used for locking; however, this combination method requires the use of screwdrivers and other hand tools for screw locking operations, which causes inconvenience in locking. , Please refer to China's Announcement No. I333847 "Curtain Assembly", which mainly includes: a main body with perforations on its bottom plate; a shaft seat with a plate body, the plate body is provided with rods and rods downwards The end of the shaft is protruding outwardly, and the rod is penetrated in the perforation of the main body; a clamping seat is provided with a perforation for the shaft of the shaft seat to pass through; a triggering member has a trigger The root of the pulling part has an ear, and the ear has an eccentric shaft groove for the assembly of the shaft of the shaft seat; The eccentric setting of the shaft groove of the piece can control the distance between the shaft seat and the clamping seat, so that the curtain assembly can be fixed on the slide rail under the corresponding clamping of the shaft seat and the clamping seat, or moved on the slide rail. Position to adjust the assembly position.
