The door and window corner brackets have a fixing and tightening function, which can make the installation of doors and windows more stable. It can also protect the edges of doors and windows and prevent damage from external factors such as impact. The general structure of the corner bracket in the prior art includes a generally L-shaped corner bracket body, and an injection molding flow channel is arranged on the surface of the corner bracket body, so that the injection molding adhesive bonds the door and window profiles and the corner bracket together. Since the adhesive is only thinly present on the surface of the corner bracket and the corner bracket is located at the joint of two door and window profiles, after the doors and windows are used for a long time, water seepage will inevitably occur at the joint, resulting in loose bonding of the door and window profiles, and even warping at the joint. At the same time, the injection molding flow channel structure on the surface of the corner bracket is complex, and special molds or multiple machining processes are required to be formed. The production cost of the corner bracket is high and needs to be improved urgently. Utility model content:

[0010] The beneficial effects of the utility model: the utility model has a simple design structure, uses a structure in which an outer tube is built inside an inner tube, and uses positioning pins for positioning connection. The outer tube, inner tube, and positioning pins are all common parts types that are easy to process, and the production cost of the angle code is low. At the same time, the injection molding cavity is located inside the angle code rather than on the surface of the angle code, which has a better waterproof effect and makes the connection strength between the angle code and the profile more stable and reliable, and is worthy of popularization and use.
