Description
Technical Field
[0001] The utility model relates to the technical field of angle brackets, in particular to an expansion type internal and external leveling door and window angle bracket. Background Art
[0002] Corner brackets are accessories used on aluminum alloy doors and windows. They are mainly used to connect two aluminum alloy profiles at the corners. Corner brackets are usually made of aluminum alloy. Aluminum alloy corner brackets have many advantages such as good stability, strong weather resistance, not easy to deform, and long service life. They are widely used in decoration projects and furniture installation. At present, there is an expansion corner bracket on the market, such as Figure 1 As shown, it mainly includes two angle code base blocks 1' with the same cross-sectional shape. The two angle code base blocks 1 are spliced into an angle code body. The angle code base block 1' is respectively provided with screw holes 2' at its two borders. The screw holes 2' are screwed with self-tapping screws 4'. A connecting block 3' is further provided at the inner side of the corresponding screw hole 2' in the angle code base block 1'. The self-tapping screw 4' passes through the connecting block 3' and is screwed therewith. The screw head 5' at the end of the self-tapping screw 4' is a narrowing structure with a wide top and a narrow bottom. The diameter of the end of the screw head 5' that is connected to the angle code base block 1' is smaller than the aperture of the screw hole 2', and the diameter of the end of the screw head 5' that is away from the angle code base block 1' is larger than the aperture of the screw hole 2'. After the two ends of the angle code body are plugged into the profile frame, the screw heads 5' need to be screwed and made It is inserted along the screw hole 2', and as the screw head 5' continuously enters the screw hole 2', the screw head 5' will open the angle bracket base blocks 1' on both sides, thereby increasing the gap between the two angle bracket base blocks 1', so that the fastening connection between the angle bracket body and the profile frame can be controlled. However, this angle bracket, since its self-tapping screws 4' are respectively arranged at positions close to the two ends of the angle bracket base block 1', when the self-tapping screws 4' are turned and the screw head 5' enters the screw hole 2', the gap opened by the screw head 5 is not uniform. The gap opened on the side with the screw head 5' is sometimes larger than the gap opened on the side without the screw head 5'. This will cause uneven force after the angle bracket and the profile frame are connected, seriously affecting the stability of the angle bracket and the profile frame after connection.
