[0003] Cold chain transportation can be road transportation, water transportation, rail transportation, air transportation, or a combination of multiple transportation modes. Cold chain transportation is an important part of cold chain logistics. Cold chain transportation is costly and involves more complex mobile refrigeration technology and insulation box manufacturing technology. Cold chain transportation management involves more risks and uncertainties.
[0004] Cold chain packaging boxes generally use foam boxes, which are box-type packaging containers made of foam plastic (porous plastic). Plastic foam is a plastic with many tiny pores inside. Foam boxes are often used in the transportation of fruits and the packaging of items.
[0005] At present, there are still certain defects in the use of packaging boxes needed for cold chain transportation. Ice bags are often added inside the foam box for insulation, and there is no insulation film on the outside. The insulation capacity of the foam box is limited, the opening is large, and the gap for heat to enter the box is too large. The overall insulation capacity is not strong and cannot support long-distance transportation. Utility Model Content

[0011] Preferably, a placement groove is provided inside the base, a reinforcing plate is movably connected inside the placement groove, and a stopper is movably connected outside the placement groove.
[0012] Preferably, a fixing block is fixedly connected to the bottom of the base, and the fixing blocks are four in number and located at the corners of the base.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. Put the ice pack into the foam box body and then put the items that need to be kept warm into the foam box body, and then insert the sealing ring on the top cover into the foam box body. The heat insulation film can improve the heat preservation capacity and support long-distance transportation.
[0015] 2. By placing ice bags in the accommodating cavity, it is possible to prevent the ice bags from damaging the items during transportation. The ice bags can prevent the water released during the melting of the ice in the bags from contaminating the transported items, thereby enhancing the functionality of the foam box body. By placing a reinforcing plate into the placement slot, the stability of the base can be enhanced. BRIEF DESCRIPTION OF THE DRAWINGS
