[0002] With the improvement of living standards, people's requirements for the doors and windows of their residences are also getting higher and higher. Aluminum alloy doors and windows have many advantages such as beautiful appearance, good sealing performance, light weight and convenience for prefabrication, and are widely used in various buildings because of being loved by people. The connection between the connecting columns and the side frames of the existing aluminum alloy door and window frames usually adopts screw connection, but this method is prone to displacement and loosening, with poor firmness and inconvenient construction.

[0003] For example, the window frame of the door and window disclosed in the application publication number CN105971471A includes a rectangular window frame formed by connecting side frames end to end in sequence. A corner connection mechanism is provided between two adjacent side frames. The corner connection mechanism includes two connection bodies made of hard materials respectively, and each connection body has a receiving groove with an opening facing the other connection member and for inserting the other connection member therein. A glass plate fixing structure is provided on the inner edge of the window frame, and the window frame is connected to the wall through a window frame fixing structure.

[0004] In the above, the fixing of the right-angle connection between the side frames is realized by inserting one side frame into the other side frame. In the insertion method in this patent, since there is no connecting member for fixing between the two side frames, only applying force to one of the side frames will cause one side frame to be inserted out of the other side frame, resulting in loosening of the two side frames and poor firmness at the right-angle connection.
