[0012] Preferably, the beams are arranged in parallel and at equal intervals.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the arch bridge structure shelf bottom beam, by introducing the design of the arch side support frame, the shelf bottom beam can effectively disperse the pressure to both sides when it is subjected to the middle pressure, thereby significantly improving the load-bearing capacity and stability of the shelf. This innovative design solves the problem that the traditional shelf is easily bent or folded from the middle when subjected to a large pressure, and greatly prolongs the service life of the shelf.

[0024] Furthermore, hollow structures 141 are provided on both sides of the arched side support frame 14 , and vertical supports 142 are installed inside the hollow structures 141 to reduce weight.

[0025] Furthermore, the arched side support frame 14 is an arched structure as a whole, the upper top surface is horizontal, and the lower part is an arc-shaped depression, so as to disperse the pressure to both sides.

[0026] Furthermore, the top of the vertical beam 12 is welded and fixed to the bottom of the horizontal beam 11 , and both ends of the vertical beam 12 are welded and fixed to the inner side of the main frame 13 to ensure the positioning of the vertical beam 12 and the horizontal beam 11 .

[0027] Furthermore, both ends of the cross beam 11 are arc-shaped structures that are bent upwards and are welded and fixed to the limiting fence 111 to ensure the positioning of the limiting fence 111.

[0028] Furthermore, the cross beams 11 are arranged in parallel and at equal intervals to ensure that the bottom is evenly stressed when objects are placed.

[0029] When the arch bridge structure shelf bottom beam of the utility model is used, firstly, the shelf body 1 is the load-bearing core of the entire structure, and is made of a solid metal material, such as steel or aluminum alloy, to ensure sufficient strength and stability. The shelf body 1 includes a plurality of parallel beams 11, which bear the weight of the goods. A plurality of vertical beams 12 are installed at the bottom of the beams 11, which intersect the beams 11 vertically to form a stable grid structure, thereby enhancing the load-bearing capacity and stability of the shelf body 1.

[0030] Secondly, the vertical rail 2 is installed on the outside of the shelf body 1 to play a supporting and fixing role. The support block 3 is installed on the vertical rail 2, and the clamping block cooperates with the positioning hole 21 on the vertical rail 2 to achieve flexible adjustment and stable fixation of the support block 3 on the vertical rail 2. The top of the support block 3 is provided with a clamping groove, which is clamped and matched with the corner of the shelf body 1 to ensure the stability and safety of the shelf body 1 during use.

[0031] When the goods are placed on the cross beam 11, their weight is transferred to other parts of the shelf body 1 through the cross beam 11 and the vertical beam 12. At this time, the arched side support frame 14 plays an important role. The design of the arched side support frame 14 can effectively disperse the pressure to both sides when the shelf body 1 is subjected to the middle pressure, thereby improving the load-bearing capacity and stability of the shelf body 1. The upper top surface of the arched side support frame 14 is horizontal, and the lower part is an arc-shaped depression. This design can better adapt to the distribution and transmission of pressure.

[0032] A limit fence 111 is installed on the top of the side of the crossbeam 11 to prevent the goods from sliding during display, thereby improving the safety of use. A hollow structure 141 and a vertical support 142 are arranged on both sides of the arched side support frame 14, which not only reduces the weight but also ensures the stability of the structure.
