AI Technical Summary
The existing aluminum profile glass door frame splicing method has problems such as complicated operation, uneven gaps, sharp outer corners, and unstable screw fixing, which can lead to door frame deformation or shaking.
The structure adopts a two-in-one seamless welded aluminum profile, which forms the first and second frames through welding. Connecting parts and glass positioning walls are set at the joints. The seamless connection is achieved by using positioning grooves and positioning strips, and the glass edges are fixed with glue to avoid corner splicing.
It improves the production efficiency of the main door panel, saves labor and material costs, enhances the aesthetics and connection stability, and eliminates safety hazards.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum profile technology, specifically relating to a two-in-one seamless welded aluminum profile structure. Background Technology
[0002] Aluminum profile glass door frames are a common door and window system, combining the strength of aluminum alloy profiles with the light transmittance of glass, and are widely used in construction, residential, and commercial spaces. Existing aluminum profile glass door frames consist of four aluminum strips with beveled corners, which are then joined together using corner brackets to form the door frame. The door frame is then fitted over the glass. This process is complex, resulting in uneven seams at the joints, sharp corners, and the need for adhesive between the glass and frame, which affects the product's appearance. The corner brackets are primarily secured with screws, which may loosen over time or under external forces (such as strong winds or frequent opening and closing), leading to frame deformation or wobbling. Utility Model Content
[0003] This addresses the technical challenge of assembling existing glass door frames using corner brackets.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a two-in-one seamless welded aluminum profile structure, including a door frame, the door frame including a first frame and a second frame, the surface of the first frame having a connecting part and a glass positioning wall, the surface of the second frame having a connecting groove and a second glass positioning wall, when the first frame and the second frame need to be connected, the connecting part is located in the connecting groove, and the glass positioning wall and the second glass positioning wall form a glass mounting groove, when the glass is assembled with the door frame, the edge of the glass is located in the mounting groove.
[0005] Furthermore, both the first and second frames are formed by welding aluminum profiles.
[0006] Furthermore, the side wall of the connecting groove is provided with several recessed positioning grooves, and the surface of the connecting part is provided with a raised positioning strip. When the first frame and the second frame are connected, the positioning strip is located in the positioning groove.
[0007] Furthermore, the mounting groove is filled with adhesive for bonding with the glass.
[0008] The present invention has the following advantages: when the first frame and the second frame need to be connected, the connecting part is provided in the connecting groove, and the glass positioning wall and the second glass positioning wall form a glass mounting groove. When the glass is assembled with the door frame, the edge of the glass is provided in the mounting groove. Adhesive is applied in the mounting groove to prevent the glass from being exposed, thus improving the aesthetics. There is no need for corner bracket splicing between the first frame and the second frame, which improves the production efficiency of the door body and saves labor and material costs.

[0015] like Figures 1 to 5 As shown, a two-in-one seamless welded aluminum profile structure includes a door frame 10, which includes a first frame 20 and a second frame 30. Both the first frame 20 and the second frame 30 are formed by welding aluminum profiles. The weld joints are ground smooth and seamlessly connected. The outer corners are ground so as not to scratch the hands and there is no safety hazard.
[0016] The first frame 20 has a connecting part 21 and a glass positioning wall 22 on the surface facing the second frame 30. The second frame 30 has a connecting groove 31 and a second glass positioning wall 32 on the surface facing the first frame 20. When the first frame 20 and the second frame 30 need to be connected, the connecting part 21 is located in the connecting groove 31. The glass positioning wall 22 and the second glass positioning wall 32 form a mounting groove 12 for the glass 11. When the glass 11 is assembled with the door frame 10, the edge of the glass 11 is located in the mounting groove 12. Adhesive is applied to the mounting groove 12 to prevent the glass 11 from being exposed and to improve the aesthetics.
[0017] To make the connection between the first frame 20 and the second frame 30 more secure, the side wall of the connecting groove 31 is provided with a number of recessed positioning grooves 33, and the surface of the connecting part 21 is provided with a raised positioning strip 23. When the first frame 20 and the second frame 30 are connected, the positioning strip 23 is placed in the positioning groove 33, making the connection between the frames more secure.
[0018] In summary, the two-in-one seamless welded aluminum profile structure of this utility model eliminates the need for corner bracket splicing between the first frame 20 and the second frame 30, thereby improving the production efficiency of the door body and saving labor and material costs.
