[0002] Corner brackets refer to the connecting parts of aluminum alloy door panels and outer frames, which are generally made of aluminum, rubber, zinc and other materials. Corner brackets are widely present in every corner of our lives, such as doors, windows, workbenches and wardrobes, 90 degrees and places that need to be fixed. High-quality corner brackets can infinitely expand the home style and make the overall decoration more three-dimensional. On the contrary, poor corner brackets will affect our home life everywhere.

[0003] At present, various aluminum door companies mainly use aluminum angle brackets. Angle brackets play the following roles in assembling doors and windows: they are mainly used for the installation of door frame main boards and the assembly of door frame components. The existing installation method of angle brackets is to glue the bottom of the angle brackets and embed them in the door leaf wire frame. Due to the different shrinkage and expansion coefficients of the plate and aluminum, cracking is prone to occur.

[0004] The Chinese patent document with the announcement number CN217712298U discloses a reinforced angle code, which includes a right-angled angle code body, two right-angled parts of the angle code body are provided with empty slots perpendicular to the right-angled surface of the angle code body, the right-angled surface of the angle code body is provided with a rubber slot connected to the empty slot, the outer wall of the angle code body is provided with a screw hole that passes through the empty slot, and the screw hole is threaded with a limit screw. The angle code structure in this scheme is relatively complex, which increases the difficulty of the angle code manufacturing process. The central axis direction of the limit screw is perpendicular to the thickness direction of the frame, which is not convenient for the limit screw to be invisible, nor is it convenient for the limit screw to be disassembled and maintained in a small space.
