Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution: an integrally formed top plate, including a plate body 1, bending beams 2 are equidistantly arranged at the top of the plate body 1, supporting edges 3 are installed at the top ends on both sides of the plate body 1, a number of installation round holes 5 are equidistantly opened at the front and rear ends of the plate body 1, docking extrusion blocks 7 are arranged directly below the installation round holes 5 at the bottom end of the plate body 1, fastening mechanisms 6 are arranged around the top end of the docking extrusion blocks 7, and the supporting edges 3 are in a C-shaped structure.

[0018] There is a wavy structure between the plate body 1 and the bent beam 2. Fixed holes 4 are provided on both sides of the front and rear ends of the plate body 1 at relative positions of the installation round openings 5. When manufacturing the plate body 1, first, two flat plates are welded together using a laser welding machine to form the plate body 1. After processing, the plate body 1 is cut using a laser cutting machine, and then bent into shape according to the drawing using a bending machine. Through this integrated forming process, not only can the structure of the 2.5-cubic-meter carriage chassis be made more solid, but also the production efficiency can be greatly improved, the process cost can be reduced, and various problems of the traditional 2.5-cubic-meter carriage can be solved at the same time. The lightweight design also improves the cargo-carrying rate, solves the problem that the traditional carriage cannot achieve modular assembly, cannot be modularly installed and transported, has limitations in structural design, and solves the problem that the welding materials of the traditional carriage are prone to cracks, cannot be disassembled after welding, and it is difficult to repair and replace parts. It also solves the problem that the traditional carriage needs to be polished after welding, and the surface cannot achieve a smooth and beautiful effect after painting;

[0019] The size of the fixed hole 4 is larger than that of the installation round opening 5. The docking extrusion block 7 is circular in structure when viewed from above, and the size of the docking extrusion block 7 is larger than that of the installation round opening 5;

[0020] Docking rotating pieces 10 are movably installed at the top ends of the docking extrusion blocks 7. A limiting rotating block 9 is installed at the bottom end of the docking rotating piece 10. The limiting rotating block 9 is in an inverted T-shaped structure. Activity circular holes 8 are provided in the middle of the docking extrusion blocks 7. The bottom end of the limiting rotating block 9 passes through the activity circular hole 8 and extends to the bottom end of the docking extrusion block 7;

[0021] The fastening mechanism 6 includes a fastening spring 601, an activity circular opening 602, and a connecting cross bar 603. Activity circular openings 602 are provided around the docking extrusion block 7. A connecting cross bar 603 is installed in the middle of the inner cavity of the activity circular opening 602. A fastening spring 601 is installed at the upper end of the connecting cross bar 603. The top end of the fastening spring 601 is connected to the bottom end of the plate body 1. When fixedly installing the plate body 1, the bolt is screwed through the inside of the installation round opening 5, so that the bottom end of the bolt rotates with the docking rotating piece 10 at the upper end of the docking extrusion block 7, and the docking extrusion block 7 is pushed downward, and the fastening spring 601 is compressed. Then, through the reaction force of the fastening spring 601, the friction force during the installation and fixation of the bolt is increased, and when installing the docking extrusion block 7 and the fastening spring 601, it is also more convenient and can be operated without special tools. Moreover, when fixedly installing the plate body 1, it is more firm, avoiding loosening and falling off after the installation and use, resulting in a reduction in the firmness of the plate body 1 during use and the occurrence of safety accidents;

[0022] The fastening springs 601 are all made of spring steel. Hook rings are installed at both the top and bottom of the fastening springs 601. A convex ring is installed around the installation round opening 5 at the bottom of the plate body 1. The hook rings at the top and bottom are respectively sleeved and connected with the convex ring and the outside of the connecting cross bar 603. When installing the fastening spring 601 in this way, the hook rings at the top and bottom are respectively sleeved and connected with the convex ring and the outside of the connecting cross bar 603. By installing the fastening spring 601, the docking extrusion block 7 will be fixed, and the installation and fixation are faster.

[0023] Working principle: When the present utility model fixedly installs the plate body 1, the bolt is screwed through the inside of the installation round opening 5, so that the bottom end of the bolt rotates with the docking rotating piece 10 at the upper end of the docking extrusion block 7, and the docking extrusion block 7 is pushed downward, and the fastening spring 601 is squeezed. Then, through the reaction force of the fastening spring 601, the friction force during the installation and fixation of the bolt is increased. Moreover, when installing the docking extrusion block 7 and the fastening spring 601, it is more convenient and can be operated without special tools. When installing and fixing the plate body 1, it is more firm, avoiding the situation of loosening and falling off after the installation and use, resulting in a decrease in the firmness of the plate body 1 during use and the occurrence of safety accidents.

[0024] When manufacturing the plate body 1, first, two flat plates are welded together using a laser welding machine to form the plate body 1. After processing is completed, the plate body 1 is processed and cut using a laser cutting machine, and then bent into shape according to the drawing using a bending machine. In this way, through the integrated forming process, not only can the structure of the 2.5 - square carriage chassis be made more solid, but also the production efficiency is greatly improved, the process cost is reduced. At the same time, various problems of the traditional 2.5 - square carriage are solved, such as the problem of improving the loading rate through lightweight design, the problem that the traditional carriage cannot achieve modular assembly, cannot be modularly installed and transported, the limitations of the structural design, and the problem that the welding materials of the traditional carriage are prone to cracks, and cannot be disassembled after welding, making it difficult to repair and replace parts. It also solves the problem that the traditional carriage needs to be polished after welding, and the surface cannot achieve a flat and beautiful effect after painting.
