[0037] Reference Figures 1-6 A splicing automatic door frame top structure is provided. This splicing automatic door frame top structure includes a door frame 1, and a top structure is provided on the door frame 1. The top structure includes a first base 21, a second base 22, a third base 23 and a fourth base 24.

[0038] The first base 21 can be detachably installed on the second base 22, the third base 23 can be detachably installed on the second base 22, and the fourth base 24 can be detachably installed on the third base 23. In application, the modular assembly of the top structure of the door frame 1 can be achieved through the detachable design of the first base 21, the second base 22, the third base 23 and the fourth base 24. Each base is small in size after being independently disassembled, which greatly reduces the risk of deformation during transportation. At the same time, no welding or complicated tools are required on site. Installation can be completed simply by splicing them in sequence, which significantly improves construction efficiency.

[0039] Reference Figures 2-5The first base 21 is an L-shaped structure with a vertical part and a horizontal part, the vertical part and the horizontal part are integrally formed, and the vertical part has an integrally formed and symmetrically arranged first snap-fit ​​strip 211.

[0040] The second base 22 has a snap-fit ​​groove 221 on the side away from the third base 23, which corresponds to the first snap-fit ​​strip 211. The snap-fit ​​groove 221 is adapted to the first snap-fit ​​strip 211. The first base 21 is detachably installed on the second base 22 through the first snap-fit ​​strip 211 and the snap-fit ​​groove 221. When in the assembled state, the horizontal part is tightly connected to the bottom of the second base 22. In application, the L-shaped structure of the first base 21 cooperates with the snap-fit ​​groove 221 of the second base 22 to form bidirectional positioning. At the same time, the vertical part is locked in position through the first snap-fit ​​strip 211 and the snap-fit ​​groove 221, and the horizontal part is attached to the bottom of the second base 22 to provide support, which can ensure connection stability, avoid loosening after assembly, and simplify the installation steps.

[0041] Reference Figures 2-6 The third substrate 23 has a snap-fit ​​surface 231 on the side away from the fourth substrate 24. The second substrate 22 has a snap-fit ​​groove 222 corresponding to the third substrate 23 on the side away from the first substrate 21, and the snap-fit ​​groove 222 is adapted to the third substrate 23. The snap-fit ​​groove 222 is fitted to the snap-fit ​​surface 231. The third substrate 23 can be detachably installed on the second substrate 22 through the snap-fit ​​surface 231 and the snap-fit ​​groove 222. The second substrate 22 has an integrally formed and symmetrical inverted U-shaped part inside. The second base 22 has an integrally formed and symmetrically arranged protrusion 224. A relief groove 225 is formed between the second base 22 and the inverted U-shaped plate 223, and the relief groove 225 is symmetrically arranged. In application, the snap-fit ​​surface 231 of the third base 23 and the snap-fit ​​groove 222 of the second base 22 are closely fitted to form a surface contact fixation, which can enhance the shear resistance, prevent displacement between the bases when the door frame 1 is subjected to force, improve the overall structural strength, and disassembly does not require damage to the parts.

[0042] Reference Figures 2-4 as well as Figure 6 The third substrate 23 has an integrally formed J-shaped card frame 232, and the J-shaped card frame 232 and the third substrate 23 surround to form a splicing groove.

[0043] The fourth base 24 has an integrally formed fourth snap-fit ​​strip 241 corresponding to the splicing groove, and the fourth snap-fit ​​strip 241 is adapted to the splicing groove. The fourth base 24 can be detachably installed on the third base 23 through the fourth snap-fit ​​strip 241 and the splicing groove. The inner top of the third base 23 has an integrally formed protrusion 233 and an arc groove 234, and the arc groove 234 is located on one side of the protrusion 233 and is connected to the inner side of the snap-fit ​​surface 231. In application, the J-shaped snap frame 232 of the third base 23 and the fourth snap-fit ​​strip 241 of the fourth base 24 are embedded and spliced. The installation does not require bolts and can be operated by hand. It is especially suitable for operation in narrow space at the top and reduces the difficulty of high-altitude installation.

[0044] The working principle of this utility model is as follows: By horizontally fixing the second base 22 to the preset position at the top of the door frame 1, the first base 21 and the third base 23 are assembled in sequence. At this time, the first snap-fit ​​strip 211 on the vertical part snaps into the snap-fit ​​groove 221 on the second base 22, and the horizontal part is in contact with the bottom of the second base 22. The snap-fit ​​surface 231 of the third base 23 snaps into the snap-fit ​​groove 222. Then, the fourth base 24 is assembled. At this time, the fourth snap-fit ​​strip 241 snaps into the splicing groove formed by the J-shaped snap-fit ​​frame 232 and the third base 23, thus completing the splicing of the top structure of the door frame 1.

[0045] This utility model provides a modular automatic door frame top structure. By adopting a modular design, the overall structure is disassembled into small base units, which can reduce transportation costs and avoid the risk of deformation. At the same time, on-site installation only requires snap-fit ​​splicing, without welding or special tools, and can be operated by a single person, which can improve installation efficiency. In case of partial damage, the faulty module can be replaced independently without the need for complete disassembly, which can reduce maintenance costs. In addition, the modular structure also supports flexible adjustment of the base unit combination according to the door opening size, adapting to different application scenarios.
