[0001] This application relates to the field of aluminum door technology, and in particular to an aluminum door with a mortise and tenon structure. Background Technology

[0002] With rapid economic development, the demand for various building components is increasing. In the building door and window industry, aluminum doors are widely used due to their lightweight, corrosion resistance, and ease of processing.

[0003] Traditional aluminum doors are mostly assembled using screws and connectors. However, screw fixing carries the risk of loosening, which may affect the stability and safety of the door after prolonged use. Furthermore, screw fixing makes it inconvenient to disassemble and assemble aluminum doors, greatly reducing the efficiency of the disassembly and assembly process.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issues that traditional aluminum door frames are mostly assembled using screws and connectors, which carries the risk of loosening and may affect the stability and safety of the door after prolonged use, and that screw fixing makes disassembly and assembly of aluminum door frames inconvenient and significantly reduces the effectiveness of disassembly and assembly, this application provides an aluminum door frame with a mortise and tenon structure.

[0006] The technical solution for a mortise and tenon structure aluminum door body provided in this application is as follows:

Each mortise and tenon component includes two connecting rods symmetrically installed inside the door frame beams. A common limiting plate is slidably disposed on the outer side of the two connecting rods, and the end of each connecting rod passes through the limiting plate and is fixedly connected to a protruding plate. A spring is disposed between the protruding plate and the limiting plate, and the spring is sleeved on the outer side of the connecting rod. Two locking rods are symmetrically installed on the limiting plate. The door frame posts have a sliding connecting groove and a locking groove communicating with the sliding connecting groove. The locking groove cooperates with the locking rod.

[0008] Preferably, the door frame beam has a beam cavity inside, and C-shaped connecting grooves are symmetrically installed inside the beam cavity. The two connecting rods are respectively fixedly installed inside the corresponding C-shaped connecting grooves.

[0009] Preferably, the door frame column has a column cavity inside, and the column cavity is arranged in a regular polygonal shape.

[0010] Preferably, the two locking rods are arranged along the width of the limiting plate, and the two connecting rods are arranged along the length of the limiting plate.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0020] This application discloses a mortise and tenon structure aluminum door body, referring to... Figure 1-4The system includes a door frame pillar 1 and a door frame beam 2. The door frame beam 2 is connected to the door frame pillar 1 by a mortise and tenon assembly 3. The mortise and tenon assembly 3 includes two connecting rods 31 symmetrically installed inside the door frame beam 2. The same limiting plate 32 is slidably provided on the outer side of the two connecting rods 31, and the end of the connecting rod 31 passes through the limiting plate 32 and is fixedly connected to a protruding plate 34. A spring 33 is provided between the protruding plate 34 and the limiting plate 32. The spring 33 is sleeved on the outer side of the connecting rod 31. Two locking rods 35 are symmetrically installed on the limiting plate 32. The two locking rods 35 are arranged along the width of the limiting plate 32, and the two connecting rods 31 are arranged along the length of the limiting plate 32. The door frame pillar 1 has a sliding connecting groove 11 and a locking groove 12 connected to the sliding connecting groove 11. The locking groove 12 cooperates with the locking rod 35.

[0021] Here, the door frame beam 2 is inserted between the two door frame posts 1, and the limiting plate 32 is inserted into the sliding connection groove 11. Then, the door frame beam 2 is pushed to move the limiting plate 32 inside the sliding connection groove 11. When the limiting plate 32 moves to the designated position, its locking rod 35 will be inserted into the locking groove 12. At the same time, the spring 33 will press against the limiting plate 32 to improve the locking effect between the locking rod 35 and the locking groove 12, thus completing the mortise and tenon connection between the door frame beam 2 and the door frame posts 1 and improving the efficiency of aluminum door installation.

[0022] Reference Figure 3 The door frame beam 2 has a beam cavity 21 inside, and C-shaped connecting grooves 22 are symmetrically installed inside the beam cavity 21. Two connecting rods 31 are respectively fixedly installed inside the corresponding C-shaped connecting grooves 22.

[0023] Here, a beam cavity 21 is provided inside the door frame beam 2, and a C-shaped connecting groove 22 is provided to fix the connecting rod 31. At the same time, the beam cavity 21 can reduce the structural weight and improve the overall load-bearing capacity of the door frame beam 2.

[0024] Reference Figure 2 The door frame column 1 has a column cavity 13 inside, and the column cavity 13 is arranged in a regular polygon.

[0025] By providing a column cavity 13 on the door frame column 1, and the column cavity 13 being arranged in a regular polygonal shape, the amount of material used can be reduced and the bending resistance of the door frame column 1 can be improved.

[0026] Reference Figure 4 A drive rod 36 is fixedly installed on the side wall of the limiting plate 32.

[0027] The drive rod 36 is provided here to facilitate the movement of the limit plate 32.

[0028] The implementation principle of the mortise and tenon structure aluminum door body in this application embodiment is as follows: In use, two door frame beams 2 are placed between two door frame columns 1. Then, the limiting plates 32 set at both ends of the door frame beams 2 are inserted into the sliding connection grooves 11 opened on the door frame columns 1. Then, the door frame beams 2 are pushed to move the limiting plates 32. The limiting plates 32 move the locking rods 35. When the locking rods 35 move a certain distance, they will align with the locking grooves 12. At the same time, the springs 33 will push the limiting plates 32 to insert the locking rods 35 into the locking grooves 12, thereby realizing the mortise and tenon splicing of the door frame beams 2 and the door frame columns 1. Conversely, by pushing the drive rods 36, the drive rods 36 drive the limiting plates 32 to squeeze the springs 33, so that the locking rods 35 move away from the locking grooves 12, thereby separating the door frame beams 2 from the door frame columns 1 and realizing the disassembly of the aluminum door body.
