Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, specifically to an improved aluminum alloy door and window corner assembly structure. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made using extruded aluminum alloy profiles for the frames, mullions, and sashes. Currently, there are three methods for assembling the corners of aluminum alloy doors and windows: The first method involves inserting corner brackets with grooves on their outer surfaces into the cavities at the corners of the door and window frames, connecting the frames by riveting them together. The second method involves inserting two corner brackets (inner and outer) into the cavities at the corners of the door and window frames, using the axial force of bolts to pull the brackets inwards, thus connecting the frames. The third method, building upon the first, further utilizes adhesive for a more secure connection. Currently, the corner-assembly methods used in aluminum alloy doors and windows result in poor sealing, allowing rainwater to seep in through the gaps, which does not meet consumer needs.

[0003] Therefore, we propose an improved aluminum alloy door and window corner assembly structure. Utility Model Content

[0004] The main purpose of this utility model is to provide an improved aluminum alloy door and window corner assembly structure. Through the design of the connecting corner bracket, it is easy to assemble the first and second corner profiles. The self-tapping screws facilitate the installation of a sealing mechanism at the right angle of the connecting corner bracket. The design of the sealing mechanism can improve the practicality of the connecting corner bracket and the waterproof performance between the first and second corner profiles, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An improved aluminum alloy door and window corner assembly structure includes a first chamfered profile, a second chamfered profile, and a connecting corner bracket. The first chamfered profile and the second chamfered profile are connected by the connecting corner bracket. The first chamfered profile and the second chamfered profile are arranged at a 45-degree angle. The two ends of the connecting corner bracket are respectively inserted into the first chamfered profile and the second chamfered profile.

[0007] The connecting angle bracket is provided with a sealing mechanism on one side at the right angle. The sealing mechanism includes a sealing plate, a self-tapping screw, a rubber strip, a mounting component, a sealing gasket, and a positioning component.

[0008] A right-angled positioning component is fixedly embedded at the right angle of the inner wall of the connecting angle bracket, and the sealing plate is fixedly connected to one side of the connecting angle bracket by self-tapping screws.

[0009] By adopting the above technical solution, the two ends of the connecting corner bracket are respectively inserted into the first and second corner profiles, one end of the first sealing strip contacts one end of the second sealing strip, and one side of the first and second sealing strips contacts the side of the rubber strip away from the sealing plate, thereby improving the sealing performance between the first and second corner profiles and preventing rainwater from entering the first and second corner profiles.

[0010] Specifically, the sealing plate is fixedly glued to the mounting component on the side away from the connecting bracket at the location of the positioning component, and the inner wall of the mounting component is in contact with the outer side of the positioning component.

[0011] Specifically, a sealing gasket is glued to the side of the sealing plate near the connecting bracket, and a mounting hole for installing self-tapping screws is provided on the side of the sealing plate away from the sealing gasket.

[0012] Specifically, a rubber strip is obliquely glued to the center of the outer side of the sealing plate, and a groove is provided at one end of the rubber strip near the mounting component, so that the rubber strip is engaged with the mounting component.

[0013] Specifically, a first sealing strip is fixedly glued to the end of the first chamfered profile near the connecting corner bracket, and a second sealing strip is fixedly glued to the end of the second chamfered profile near the connecting corner bracket.

[0014] Specifically, one end of the first sealing strip contacts one end of the second sealing strip, and one side of both the first and second sealing strips contacts the side of the rubber strip away from the sealing plate.

[0015] The beneficial effects of this utility model are as follows: The improved aluminum alloy door and window corner assembly structure described in this utility model, through the design of the connecting corner bracket, facilitates the assembly of the first and second corner profiles. Self-tapping screws facilitate the installation of a sealing mechanism at the right angle of the connecting corner bracket. The sealing mechanism design improves the practicality of the connecting corner bracket and enhances the waterproofing between the first and second corner profiles. Both ends of the connecting corner bracket are inserted into the first and second corner profiles respectively. One end of the first sealing strip contacts one end of the second sealing strip, and one side of both the first and second sealing strips contacts the side of the rubber strip furthest from the sealing plate. This improves the sealing between the first and second corner profiles, preventing rainwater from entering them. Attached Figure Description
