Rubber strips 25 are provided on the inner walls of the back panel 21, the pair of side panels 22, and the front panel 23. The rubber strips 25 surround the ice plate 3 to form a positioning space for installing the ice plate 3. A chute 26 for the top ice plate 3 to slide and embed is formed between the upper ends of all the rubber strips 25 and the top cover 24, realizing the support and convenient installation of the top ice plate 3.

[0023] As Figure 1 , Figure 2 shown, the perimeter of the tray 1 extends upward to form a retaining wall 5 that abuts against the outer walls of the back panel 21, the pair of side panels 22, and the front panel 23. First indentations 51 for the ends of the retaining wall 5 to be inserted are provided at the lower ends of the back panel 21, the pair of side panels 22, and the front panel 23.

[0024] As Figure 1 , Figure 2 shown, corner guards 6 are provided at the connection positions of the back panel 21, the pair of side panels 22, the front panel 23, and the top cover 24. Second indentations 61 for the ends of the corner guards 6 to be inserted are provided on the back panel 21, the pair of side panels 22, the front panel 23, and the top cover 24.

[0025] As Figure 1 , Figure 2 shown, there are three crosswise and longitudinal binding straps 4, which surround the back panel 21, the pair of side panels 22, the front panel 23, and the top cover 24. Third indentations 41 that are cross-shaped and for the crosswise and longitudinal binding straps 4 to be inserted are provided on the back panel 21, the pair of side panels 22, and the front panel 23.

[0026] When the packing box needs to be assembled and used, first place the tray 1 on the ground, then lay a layer of cushion in the tray 1, and then place the back panel 21 vertically on the tray 1 and use the rear retaining wall 5 for abutting and supporting. Then place the left and right side panels 22 vertically on the tray 1 and use the retaining walls 5 on both sides for abutting and supporting.

[0027] And during the installation process of the back panel 21 and the side panels 22, due to the assistance of the first indentations 51, the positioning installation of the back panel 21 and the side panels 22 can be quickly achieved, ensuring the installation accuracy and at the same time increasing the connection stability between the back panel 21 and the side panels 22.

[0028] Then place the top cover 24 above the back panel 21 and the side panels 22, and install the corner guards 6 at the connection positions of the back panel 21, the pair of side panels 22, and the top cover 24. With the assistance of the second indentations 61, the quick positioning of the corner guards 6 is realized, ensuring the installation accuracy of the corner guards 6 and achieving stable protection.

[0029] Then, use tape to preliminarily fix the connection positions of the back panel 21, a pair of side panels 22, and the top cover 24, and also bond the corner guards 6 to complete the preliminary assembly of the insulation box 2.

[0030] Then, place the ice plate 3 at the bottom on the tray 1, so that the ice plate 3 at the bottom is located below all the rubber strips 25, and use the rubber strips 25 to press tightly around the ice plate 3 at the bottom to achieve the limit of the ice plate 3 at the bottom. Then, bond and fix the ice plates 3 on both sides to a pair of side panels 22, so that the lower end of the ice plate 3 on the side presses tightly against the ice plate 3 at the bottom and is located within the installation space surrounded by the rubber strips 25 to achieve the fixed installation of the ice plate 3 on the side.

[0031] Then, bond and fix the back ice plate 3 to the back panel 21, so that the lower end of the back ice plate 3 presses tightly against the ice plate 3 at the bottom and is located within the installation space surrounded by the rubber strips 25 to achieve the fixed installation of the back ice plate 3. Finally, insert the top ice plate 3 into the chute 26 formed between the upper end of the rubber strip 25 and the top cover 24 to complete the support and installation of the top ice plate 3.

[0032] Subsequently, the goods can be neatly loaded into the insulation box 2, and then the front ice plate 3 is bonded and fixed to the front upper part, so that the front ice plate 3 is located within the installation space surrounded by the rubber strips 25. Subsequently, the front panel 23 is vertically inserted into the enclosure 5 on the tray 1 to close the front end of the insulation box 2.

[0033] Finally, install and fix the remaining corner guards 6 and bond and fix them with tape. Then, wind the binding straps 4 horizontally and vertically around the outer wall of the insulation box 2, and with the assistance of the third indentation 41, achieve the rapid positioning of the binding straps 4, ensure the installation accuracy of the binding straps 4, and achieve the stable packing and fixing of the insulation box 2 to prevent it from falling apart during transportation.

[0034] Therefore, by respectively arranging ice plates 3 on the bottom wall, top wall, and all around of the insulation box 2, the all-round surrounding freshness preservation of the items in the insulation box 2 is realized, and the temperature in the insulation box 2 is kept constant, thereby ensuring the stability during the cold chain transportation of the goods.

[0035] At the same time, by setting the modular insulation box 2, it is convenient for the split storage and transportation of the insulation box 2, and even the production is relatively convenient. At the same time, the insulation box 2 can be quickly spliced and assembled on the tray 1 to improve the convenience during use.

[0036] As Figure 4 、 Figure 4 、 Figure 5 shown, the ice plate 3 includes a housing 31 and ice bags 32. The housing 31 is arranged in a plate shape with a hollow interior, and the ice bags 32 are arranged in three rows side by side. Each row of ice bags 32 is composed of a plurality of independent bag bodies connected together and is fixed in the housing 31 by double-sided tape.

[0037] like Figure 4 、 Figure 4 、 Figure 5 As shown, the outer shell 31 includes a bottom paperboard 33 , a pair of side paperboards 34 and a pair of surface paperboards 35 .

[0038] like Figure 4 、 Figure 4 、 Figure 5 As shown, the bottom cardboard 33 is arranged in a rectangular shape, and a pair of side cardboards 34 are arranged on both sides of the bottom cardboard 33 and are folded to be vertical. A pair of surface cardboards 35 connects the pair of side cardboards 34 and covers the bottom cardboard 33 after being folded.

[0039] like Figure 4 、 Figure 4 、 Figure 5 As shown, both ends of the bottom paperboard 33 are turned upward to form inner edge panels 36 , and both ends of the surface paperboard 35 are turned downward to form outer edge panels 37 that press the inner edge panels 36 .

[0040] When the ice board 3 needs to be assembled for use, the integrally formed shell 31 is laid on the ground, and then the three rows of ice packs 32 are bonded and fixed to the bottom cardboard 33. Then the inner edge plate 36 on the bottom cardboard 33 is bent upward, and then the side cardboard 34 is bent upward.

[0041] Then, the pair of surface cardboards 35 are controlled to bend again so that the surface cardboards 35 cover the ice bag 32, and then the outer edge plate 37 is flipped downward to cover the outside of the inner edge plate 36. Finally, the entire shell 31 is wrapped and fixed with tape to complete the assembly of the ice plate 3. The ice plate 3 can then be placed in the freezer for freezing, and then the frozen ice plate 3 can be taken out for installation.

[0042] like Figure 4 、 Figure 4 、 Figure 5 As shown, the surface cardboard 35 is provided with two rows of surface ventilation holes 351, which are staggered. The number of surface ventilation holes 351 in the outer row is the same as the number of bags in the ice pack 32, and is aligned with the middle of each bag. The inner row of surface ventilation holes 351 is aligned with the connection between adjacent bags and is located at the connection between two adjacent rows of ice packs 32.

[0043] like Figure 4 、 Figure 4 、 Figure 5 As shown, a plurality of notches 352 are provided on one side of the surface cardboard 35. The plurality of notches 352 are spliced together to form positioning holes 353 for the tape to wrap around. The positioning holes 353 are in the same straight line as a row of surface ventilation holes 351 close to the outside.

[0044] As Figure 4 , Figure 4 , Figure 5 shown, a plurality of lateral ventilation holes 341 are equidistantly arranged on the lateral cardboard 34, and the positioning holes 353 are aligned between two adjacent lateral ventilation holes 341.

[0045] By providing the surface ventilation holes 351 and the lateral ventilation holes 341 on the outer shell 31, the cold air can be discharged along the surface ventilation holes 351 and the lateral ventilation holes 341, ensuring the cooling inside the incubator 2. At the same time, the surface ventilation holes 351 are aligned with each bag body and the connection position of the ice bag 32, realizing the full discharge of the cold air.

[0046] Meanwhile, a notch 352 is provided at a unique position, and the position of the tape is fixed by using the positioning hole 353 formed by the notch 352, so that the tape can avoid the lateral ventilation holes 341 when winding, and at the same time wind around the outside of each bag body of the ice bag 32, realizing the tight winding and fixing of the tape on the premise of minimizing the cold air dissipated by the ice bag 32.
