[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Example: Please refer to Figures 1-4 This embodiment provides a weld-free beam structure for a shelf, including two vertically arranged shelf uprights 1 and a horizontally arranged beam body 2 installed between the two shelf uprights 1. Both ends of the beam body 2 are connected to hanging plates 3, which are fixedly connected to the adjacent shelf uprights 1. The hanging plates 3 are used as components to connect the beam body 2 and the shelf uprights 1, thereby achieving a stable connection between the beam body 2 and the shelf uprights 1.
[0025] In this embodiment, as Figure 2 and Figure 3 As shown, the hanging plate 3 includes a side abutment plate 31, and a connecting part 33 is provided on one side of the bottom of the side abutment plate 31. The main body of the crossbeam 2 is fixedly connected to the connecting part 33 through a connector 34. The connecting part 33 includes a first bent plate 331 provided on one side of the bottom of the side abutment plate 31. A second bent plate 332 is provided at both ends of the first bent plate 331. An installation cavity is formed between the side abutment plate 31, the first bent plate 331 and the second bent plate 332. The end of the main body of the crossbeam 2 is placed in the installation cavity. A fixing hole 333 is provided on the second bent plate 332. A fixing hole is provided at the end of the main body of the crossbeam 2. The through hole at position 333 connects the main body of the crossbeam 2 and the second bent plate 332 through the connecting piece 34 passing through the fixing hole 333 and the through hole. During assembly, simply place the end of the main body of the crossbeam 2 into the mounting cavity of the connecting part 33, and then connect and fix the connecting part 33 to the main body of the crossbeam 2 through the connecting piece 34. The connecting piece 34 can be a rivet or a bolt. The connecting part 33 can effectively support the main body of the crossbeam 2, ensuring a stable connection. It also eliminates the need for extensive welding in the traditional way, simplifying the assembly steps and time. This is not only environmentally friendly but also saves a lot of labor costs.
[0026] In this embodiment, as Figure 3As shown, the first bending plate 331 is bent at 90° to the side abutment plate 31, and the second bending plate 332 is bent at 90° to the first bending plate 331. When the side abutment plate 31 is in a vertical state, the first bending plate 331 is bent horizontally at 90° relative to the side abutment plate 31, and the second bending plate 332 is bent upward at 90° relative to the first bending plate 331. Through the bending arrangement of the first bending plate 331 and the second bending plate 332, an installation cavity can be formed between the side abutment plate 31, the first bending plate 331 and the second bending plate 332 for the load-bearing connection of the crossbeam body 2.
[0027] In this embodiment, as Figure 3 As shown, a positioning plate 32 is provided at the front end of the side abutment plate 31. The positioning plate 32 is bent at 90° with the side abutment plate 31. The side abutment plate 31 and the positioning plate 32 are placed on the outside of the shelf upright 1. The cross-section of the side abutment plate 31 and the positioning plate 32 is an L-shaped structure. When the hanging piece 3 is connected to the shelf upright 1, the side abutment plate 31 is placed against the side of the shelf upright 1 and the front end of the shelf upright 1 for the initial positioning and assembly connection of the hanging piece 3 and the shelf upright 1.
[0028] In this embodiment, as Figure 4 As shown, the side abutment plate 31, the positioning plate 32, the first bending plate 331 and the second bending plate 332 are integrally bent to improve the structural strength of the hanging piece 3.
[0029] In this embodiment, as Figure 3 As shown, several fixing holes are evenly spaced along the longitudinal direction on the shelf upright 1. A positioning hook 321 is fixedly connected to the inner side of the positioning plate 32. The positioning hook 321 corresponds to the position of the fixing hole on the shelf upright 1. The positioning hook 321 is engaged in the fixing hole on the shelf upright 1. The positioning plate 32 is also provided with a connecting hole 322, which corresponds to the position of the fixing hole on the shelf upright 1. The positioning plate 32 and the shelf upright 1 are connected and fixed by bolts passing through the connecting hole 322 and the fixing hole. When assembling the hanging piece 3 with the shelf upright 1, the positioning hook 321 is passed through the fixing hole on the shelf upright 1 to achieve the initial positioning connection between the hanging piece 3 and the shelf upright 1. Then, the hanging piece 3 is connected and fixed with the shelf upright 1 by bolts to achieve a stable assembly between the hanging piece 3 and the shelf upright 1.
[0030] In this embodiment, the outer side of the hanging plate 3 is coated with an anti-corrosion coating. After the anti-corrosion coating is cured, a dense film layer is formed, making it difficult for corrosive media to wet the metal surface, thereby improving the anti-corrosion performance of the hanging plate 3 and increasing its service life.
[0031] Working principle: In use, the end of the main body 2 of the crossbeam is placed in the mounting cavity of the connecting part 33 of the hanging piece 3, and then the connecting part 33 is connected and fixed to the main body 2 of the crossbeam through the connector 34, thus completing the assembly connection of the hanging piece 3 at both ends of the main body 2 of the crossbeam. Then, the positioning hook 321 on the hanging piece 3 is passed through the fixing hole on the shelf column 1 to achieve the initial positioning connection between the hanging piece 3 and the shelf column 1. Then, the hanging piece 3 is connected and fixed to the shelf column 1 through the bolt, thus firmly assembling the hanging pieces 3 at both ends of the main body 2 of the crossbeam to the shelf column 1. The hanging piece 3 is integrally bent and formed, and the connecting part 33 of the hanging piece 3 can effectively support the main body 2 of the crossbeam, ensuring a stable connection. Moreover, it eliminates the need for large-scale welding in the traditional way, simplifying the assembly steps and time. It is not only environmentally friendly but also saves a lot of labor costs.
[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
