[0002] Cold storage boards are generally pre-produced by manufacturers and have fixed lengths, widths and thicknesses. The polyurethane cold storage board uses lightweight polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that its heat insulation performance is very good. However, in the existing polyurethane cold storage boards, the polyurethane boards inside are usually single-layer, which makes the heat preservation effect of a single cold storage board limited and is not conducive to actual use.

[0003] For example, a reinforced polyurethane cold storage board with the publication number of CN213296713U relates to the technical field of polyurethane cold storage boards. The reinforced polyurethane cold storage board includes a polyurethane board. Both sides of the outside of the polyurethane board are provided with side plates. Among them, a limiting tube is fixed on one side of one of the side plates. The limiting tube is located inside the polyurethane board, and a connecting rod is connected to the limiting tube through a telescopic mechanism. The connecting rod and the other side plate are fixedly connected through a fixed disk. This technical solution also has the above-mentioned technical problems. Content of the Utility Model

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , a multi-layer composite polyurethane cold storage board, including a cold storage board main body 1 and a bottom plate 6. The side of the bottom plate 6 is connected to the inner side of the cold storage board main body 1. The material of the bottom 6 is a kind of alloy steel, which can effectively resist impact. A movable support plate 5 is arranged above the bottom plate 6. A first polyurethane board 15 is arranged on the top of the support plate 5. A sponge pad 16 is arranged on the top of the first polyurethane board 15. A second polyurethane board 17 is arranged on the top of the sponge pad 16. The sponge pad 16 has good elasticity, which can avoid the first polyurethane board 15 and the second polyurethane board 17 from contacting too closely when they are fixed, causing damage to both of them. It should be noted that in the present invention, both the first polyurethane board 15 and the second polyurethane board 17 are regarded as polyurethane boards.

[0020] Chutes 2 are opened on the left and right side walls of the cold storage board main body 1. A first slider 3 is slidably connected in the chute 2. A plurality of springs 4 are installed in the chute 2. The specific number of springs 4 in each chute 2 is three. The top of the spring 4 is connected to the bottom of the first slider 3.

The fastening bolts 21 are threadedly connected to both the connecting thread one and the connecting thread two at the same time, so that the fastening bolts 21 are threadedly connected to the first fixing holes 19 and the second fixing holes 20 at the same time to fix the front side plate 18 and connect the front side plate 18 to the cold storage board main body 1.

[0025] During use, place the first polyurethane board 15 on the top of the support plate 5. The spring 4 will drive the support plate 5 to move upward to support the first polyurethane board 15. Then place the sponge pad 16 on the top of the first polyurethane board 15, and then place the second polyurethane board 17 on the top of the sponge pad 16. Then rotate the rotating handle 10 to make the threaded rod 9 rotate, so that the second slider 11 moves downward, drive the fixing plate 13 to move downward through the connecting block 12, and make the bottom of the fixing plate 13 in close contact with the top of the second polyurethane board 17. Through the mutual cooperation of the fixing plate 13 and the support plate 5, the first polyurethane board 15, the sponge pad 16 and the second polyurethane board 17 are fixed. Then move the front side plate 18 to make the rear side of the front side plate 18 in close contact with the front side of the cold storage board main body 1. Then rotate the fastening bolts 21 to make the fastening bolts 21 threadedly connected to the first fixing holes 19 and the second fixing holes, and fix the front side plate 18 to connect the front side plate 18 to the cold storage board main body 1.
