[0031] To better understand the purpose, structure, and function of this utility model, the multi-layer structure insulated box of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] like Figure 1-8As shown, the multi-layer insulated box of this utility model includes an insulated box body 1 and a top cover 2. The top of the insulated box body 1 is connected to the top cover 2 via a pivot. An inner box 5 is embedded inside the insulated box body 1. A first insulation board 12 and a second insulation board 13 are installed on the inner side of the inner box 5. A bottom frame 9 is provided on the inner side of the insulated box body 1. A positioning plate 6 is connected to the top of the bottom frame 9. An insulation frame 8 is provided above the bottom frame 9. A positioning groove 7 is opened at the bottom of the insulation frame 8. The positioning plate 6 is embedded in the positioning groove 7. Due to the presence of the positioning plate 6 and the positioning groove 7, it is convenient to install the insulation frame 8. The top of the bottom frame 9 and the outer side of the inner box 5 are equipped with an insulation frame 8. By installing the inner box 5 inside the device body and the insulation frame 8 outside the inner box 5, and by secretly rotating the first insulation board 12 and the second insulation board 13 on the inner side, the insulation frame 8, the first insulation board 12 and the second insulation board 13 are installed inside the insulation box body 1. This can improve the insulation time. Moreover, when the insulation structure inside and outside the inner box 5 is obviously not insulating, a new insulation frame 8, the first insulation board 12 and the second insulation board 13 can be taken out and reassembled.

[0033] The bottom of the insulated box body 1 is connected to the base 27. The top of the base 27 is equipped with a first reinforcing frame 14 and a second reinforcing frame 15. The first reinforcing frame 14 and the second reinforcing frame 15 are symmetrically distributed. The inside of the first reinforcing frame 14 and the second reinforcing frame 15 is provided with a limiting groove 21. The limiting plate 20 is embedded inside the limiting groove 21. The top of the limiting plate 20 is connected to a ball-shaped pull rod 22. The bottom of the limiting plate 20 is provided with a locking plate 23. The top of the base 27 is provided with a locking groove 24. The locking plate 23 is embedded inside the locking groove 24. By installing a base 27 on the outside of the insulated box body 1, and installing a first reinforcing frame 14 and a second reinforcing frame 15 on the top of the base 27, before using the insulated box, the first reinforcing frame 14 and the second reinforcing frame 15 are removed and assembled on the outside of the insulated box body 1. By dragging the limiting plate 20 inside the limiting groove 21, the locking plate 23 is inserted into the top of the base 27. In this way, the reinforcing structure can be spliced ​​with the base 27 structure. In the event of collision or squeezing during transportation, the externally installed reinforcing structure can protect the inside of the insulated box.

[0034] A magnetic groove 11 is provided on the inner side of the inner box 5. The outer sides of the first insulation board 12 and the second insulation board 13 are connected to the metal plate 10. The magnetic groove 11 magnetically attracts the metal plate 10. Since the metal plate 10 and the magnetic groove 11 are provided, it is convenient to install the first insulation board 12 and the second insulation board 13 on the inner side of the inner box 5. When the insulation effect is not good, the first insulation board 12 and the second insulation board 13 can be disassembled and a new insulation structure can be taken out and reassembled.

[0035] The first reinforcing frame 14 has a plate 16 and a metal rod 18 on its side, and the second reinforcing frame 15 has a slot 17 and a magnetic sleeve 19 on its side. The metal rod 18 is embedded in the magnetic sleeve 19, and the plate 16 is embedded in the slot 17. By providing the plate and the slot 17, it is convenient to initially splice and fix the first reinforcing frame 14 and the second reinforcing frame 15.

[0036] The inner side of the top cover 2 is connected to the sealing plate 25, and the top of the insulated box body 1 is provided with a sealing groove 26. The sealing plate 25 is embedded in the inside of the sealing groove 26. Due to the sealing plate 25 and the sealing groove 26, the inside of the insulated box body 1 can be sealed to prevent external air from entering the insulated box body 1.

[0037] The side of the insulated box body 1 is provided with a buckle 4, and the side of the top cover 2 is provided with a buckle 3. The buckle 3 is sleeved on the outside of the buckle 4. Because of the buckle 4 and the buckle 3, it is convenient to connect and fix the top cover 2 and the insulated box body 1.

[0038] The working principle of this multi-layer insulated box is as follows: When using this equipment, the main body of the device first needs to be moved to a suitable position. After being moved, it can be placed on a flat surface. However, in order to better protect the goods inside the insulated box body 1, a base 27 is installed on the outside of the insulated box body 1, and a first reinforcing frame 14 and a second reinforcing frame 15 are installed on the top of the base 27. The side of the first reinforcing frame 14 is equipped with a plate 16 and a metal rod 18. The side of the second reinforcing frame 15 is provided with a slot 17 and a magnetic sleeve 19. The inside of the reinforcing frame is equipped with... The limiting plate 20 and the clamping plate 23, along with the ball-shaped pull rod 22 installed on the top, are used to first remove the first reinforcing frame 14 and the second reinforcing frame 15. The metal rod 18 is inserted into the magnetic sleeve 19, and the insert plate 16 is embedded inside the slot 17. Then, the ball-shaped pull rod 22 is held, and the limiting plate 20 inside the limiting groove 21 is dragged to insert the clamping plate 23 into the clamping slot 24 at the top of the base 27. This allows the reinforcing structure to be spliced ​​with the base 27 structure. Furthermore, in the event of collision or compression during transportation, the externally installed reinforcing structure can protect the interior of the insulated box. For protection, and secondly, to better insulate the goods, an inner box 5 is installed inside the main body of the device, and an insulation frame 8 is installed outside the inner box 5. The first insulation plate 12 and the second insulation plate 13 are concealed on the inner side, which can improve the overall insulation effect of the insulated box. Before storing the goods, the positioning groove 7 at the bottom of the insulation frame 8 is fitted onto the outside of the positioning plate 6 at the top of the bottom frame 9. Then, the metal plates 10 on the sides of the first insulation plate 12 and the second insulation plate 13 are embedded in the magnetic groove 11. In this way, the insulation structure can be installed inside the insulated box body 1, which not only improves the insulation effect but also... The insulation duration is long, and when the insulation structure inside and outside the inner box 5 shows obvious signs of insulation, a new insulation frame 8, first insulation board 12 and second insulation board 13 can be taken out and reassembled. The insulation effect is strong when in use. Finally, the items to be transported are loaded into the inner box. The staff rotates the top cover 2 through the pivot and puts the buckle 3 into the inside of the buckle body 4. In this way, the two can be assembled. The sealing plate 25 on the inner side of the top cover 2 can also be embedded in the sealing groove 26 to maintain the airtightness of the box and thus extend the insulation effect.
