By installing the glass panel inside the aluminum frame, which is composed of a first and a second aluminum plate connected by a plug rod, the aluminum frame can be easily disassembled. Furthermore, edging is installed at both corners on one side of the aluminum frame, and two reinforcing blocks are installed on the other side, effectively preventing deformation of the aluminum frame.

[0003] The reinforcing block is composed of concave plates, the inner diameter of which matches the thickness of the aluminum frame. A mounting base is provided on one side of the reinforcing block, allowing the hinge to connect to the mounting base during installation of the aluminum cabinet door, preventing direct contact and compression of the aluminum frame. This invention features a long service life.

[0004] However, the cutting and welding points of the cabinet door are prone to stress concentration, which can cause the cabinet door to deform or crack. This requires additional cutting steps, increasing labor time and material waste. This solution does not result in high quality of cabinet door use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a non-cutting method for manufacturing internally welded aluminum cabinet doors. This solves the problem that stress concentration easily occurs at the weld points when cutting cabinet doors, leading to easy deformation or cracking of the cabinet doors, requiring additional cutting steps, increasing labor time and material waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum cabinet door that is welded without cutting off the inside, comprising a cabinet door frame and an internal support frame. The cabinet door frame is formed by aluminum profiles, and the internal support frame is an aluminum mesh structure. It is fixedly connected to the inner wall of the cabinet door frame by welding points. The welding points are evenly distributed in the non-cut-off area inside the cabinet door frame, and the continuity of the internal support frame is not cut off after welding.

[0007] In one specific embodiment, the grid structure of the internal support frame is formed by alternating horizontal and vertical reinforcing ribs, with the horizontal reinforcing ribs parallel to the long side of the cabinet door frame and the vertical reinforcing ribs parallel to the short side of the cabinet door frame.

[0008] In a specific embodiment, a locally thickened welding zone is provided at the intersection of the transverse stiffener and the longitudinal stiffener, and the welding point is located within the thickened welding zone.

[0009] In one specific embodiment, the inner wall of the cabinet door frame is provided with a filling groove, and the end of the internal support frame is embedded in the filling groove and fixed by welding points.

[0010] In one specific embodiment, the outer surface of the cabinet door frame is covered with an anti-oxidation coating, and the surface of the internal support frame is coated with an anti-corrosion layer.

[0011] In one specific embodiment, the internal support frame and the cabinet door frame are fixed together by a detachable connector, which is a bolt.

[0012] Compared with the prior art, this utility model provides a cabinet door that does not cut through the internal welded aluminum, which has the following advantages:

[0013] The technical solution disclosed in this utility model avoids the stress concentration problem caused by cutting the internal support frame in traditional processes by setting the welding points in the non-cut area inside the cabinet door frame, thus ensuring the continuity of the internal support frame and improving the overall deformation resistance of the cabinet door. The grid structure formed by the transverse and longitudinal reinforcing ribs disperses the force direction of the cabinet door, reducing the risk of local cracking. The design of the locally thickened welding area allows the welding points to be concentrated in the thickened area for high-precision spot welding, eliminating the need for subsequent cutting steps and reducing processing time. By optimizing the welding position and grid support structure, the problem of low strength and easy corrosion caused by cutting in traditional processes is solved. It has the advantages of high processing efficiency and long service life, and is suitable for the furniture and construction fields. Attached Figure Description

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 As an embodiment of the present utility model, an aluminum cabinet door that is welded without cutting off the inside includes a cabinet door frame 1 and an internal support frame 2. The cabinet door frame 1 is enclosed by aluminum profiles, and its internal support frame 2 is an aluminum mesh structure. It is fixedly connected to the inner side wall of the cabinet door frame 1 through welding points. The welding points are evenly distributed in the non-cut-off area inside the cabinet door frame 1, and the continuity of the internal support frame 2 is not cut off after welding.

[0022] This specific embodiment addresses the problem of stress concentration at the welding points during cabinet door cutting, which leads to deformation or cracking, requiring additional cutting steps and increasing labor time and material waste. This invention avoids stress concentration caused by cutting the internal support frame 2 in traditional processes by placing the welding points on the non-cut area inside the cabinet door frame 1, ensuring the continuity of the internal support frame 2 and improving the overall deformation resistance of the cabinet door. The grid structure formed by the transverse reinforcing ribs 21 and longitudinal reinforcing ribs 22 disperses the force direction of the cabinet door, reducing the risk of local cracking. The design of the locally thickened welding area allows for high-precision spot welding concentrated in the thickened area, eliminating the need for subsequent cutting steps and reducing processing time. By optimizing the welding position and grid support structure, this invention solves the problems of low strength and easy corrosion caused by cutting in traditional processes, offering advantages such as high processing efficiency and long service life, and is suitable for the furniture and construction industries.

[0023] The internal support frame 2's grid structure is formed by interlacing transverse reinforcing ribs 21 and longitudinal reinforcing ribs 22. The transverse reinforcing ribs 21 are parallel to the long side of the cabinet door frame 1, and the longitudinal reinforcing ribs 22 are parallel to the short side of the cabinet door frame 1. In this specific embodiment, a locally thickened welding area is provided at the intersection of the transverse reinforcing ribs 21 and the longitudinal reinforcing ribs 22, and the welding point is located within this thickened welding area. By setting the welding point in the non-cut area inside the cabinet door frame 1, the stress concentration problem caused by cutting the internal support frame 2 in traditional processes is avoided, ensuring the continuity of the internal support frame 2 and improving the overall deformation resistance of the cabinet door. The grid structure formed by the transverse reinforcing ribs 21 and the longitudinal reinforcing ribs 22 disperses the force direction of the cabinet door, reducing the risk of local cracking. The design of the locally thickened welding area allows the welding points to be concentrated in the thickened area for high-precision spot welding, eliminating the need for subsequent cutting steps and reducing processing time. Thus, by optimizing the welding position and grid support structure, the problems of low strength and easy corrosion caused by cutting in traditional processes are solved. It has the advantages of high processing efficiency and long service life, and is suitable for the furniture and construction fields.

[0024] In this specific embodiment, the inner sidewall of the cabinet door frame 1 is provided with a filling groove 4, and the end of the internal support frame 2 is embedded in the filling groove 4 and fixed by welding points. The embedded cooperation between the filling groove 4 and the end of the internal support frame 2 simplifies the positioning process and improves the welding accuracy.

[0025] In this specific embodiment, the outer surface of the cabinet door frame 1 is covered with an anti-oxidation coating, and the surface of the internal support frame 2 is coated with an anti-corrosion layer. The surface coating completely covers the surface and blocks the oxidation path.

[0026] In this specific embodiment, the internal support frame 2 and the cabinet door frame 1 are assisted in being fixed by a detachable connector 3, which is a bolt. The auxiliary fixing design of the detachable connector 3, such as a buckle or bolt, allows for quick disassembly and assembly of the internal support frame 2, which facilitates later maintenance or adjustment of the cabinet door size as needed, thereby reducing maintenance costs.

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
