[0026] The front wall 2 is sewn by a magnesium alloy frame and a soft composite heat-insulating material. The front wall 2 includes a door body so that goods can enter the foldable heat-insulating box.

[0027] The bottom wall 5 is a new type of CFP composite board material, including upper and lower layers of continuous glass fiber reinforced polypropylene sheets and a honeycomb core of a sandwich layer, so as to facilitate the transportation and waterproofing of the foldable thermal insulation box.

[0028] The soft heat-insulating tarpaulin 6, the front wall 2 and the bottom wall 5 together form a storage room of the foldable heat-insulating box for storing goods.

[0029] The supporting structure is arranged inside the foldable thermal insulation box, and includes an internal supporting beam 1, an internal supporting rod and a support 3, and is used to support a soft thermal insulation tarpaulin 6.

[0030] In specific implementation, when the foldable incubator is unfolded, the front wall 2 is first unfolded (so that the front wall 2 and the bottom wall 5 are in a vertical state), and then the internal support rods are installed. When folding, the internal support rods are first disassembled, and then the front wall 2 is turned down and folded.

[0031] The bottom wall 5 is made of a new CFP composite board, which is lighter, has better load-bearing performance, and has excellent waterproof and moisture-proof performance, is easy to use, and has low cost compared to the traditional composite large board bonding structure.

[0037] The door lock is arranged on one side of the middle of the door body.

[0038] According to the embodiment provided by the present invention, the anti-collision plate is made of rubber.

[0039] According to the embodiment provided by the present invention, the door body is connected to the front wall 2 via a hinge.

[0040] According to the embodiment provided by the present invention, a plurality of cushion blocks 4 are arranged at the bottom of the bottom wall 5 to protect the bottom wall 5 and facilitate the transportation of the foldable thermal insulation box.

[0041] According to the embodiment provided by the present invention, a modular shelf is provided in the storage room for containing cargo turnover baskets.

[0042] The modular rack includes partitions and pillars.

[0043] The partitions include the first partition, the second partition, the third partition and the fourth partition. The first partition is a movable partition placed on the pillar so as to be pulled out so that the modular shelf can be used to place large-volume goods. The second partition, the third partition and the fourth partition are welded to the pillars respectively.

[0044] It should be noted that in order to solve the problems of poor air circulation, unstable stacking, difficult loading and unloading, and low space utilization during the stacking of goods, modular shelves are installed in the insulation box. The main function of the shelf is to place food turnover boxes between the compartments to ensure the classified storage of the transported non-staple food. The food turnover boxes are consistent with the existing equipment, which facilitates the standardization, modularization, and generalization of transportation operations to improve work efficiency.

[0045] The modular shelves are made of magnesium alloy, with guardrails on the top, and can also hold items (such as sealed turnover boxes). Two sets of shelves are installed in the incubator, one on the left and one on the right.

[0046] The main body of the shelf is a magnesium alloy frame structure, which is divided into two parts: pillars and partitions. Table 2 is a comparison table of common shelf materials.

[0047] Table 2 Comparison of common shelf materials

[0048]

[0049] To accommodate the shipment of large-sized goods, the shelf partitions are all movable partitions. If you encounter larger items, you can pull out a layer of partitions to store them. A fence can be added to the top part to place other items.

[0050] According to the embodiment provided by the present invention, a groove is provided at the upper end of the bottom wall 5 so that the pillar can be inserted into the groove for fixation.

[0051] It should be noted that the pillars of each set of shelves are respectively inserted into the fixed grooves of the bottom wall 5, and the installation of the shelves should be convenient and quick. In order to facilitate personnel operation and air circulation, a channel with a width of about 730mm is left in the middle of the cold storage after the shelves are installed. This part of the space can also be used to store special-shaped packages or insulation barrels. At the same time, the user unit can disassemble and assemble the shelves as needed.

[0052] According to the embodiment provided by the present invention, the outer surface material of the soft thermal insulation tarpaulin 6 is waterproof tent cloth, the lining material is silver-coated Oxford cloth, and the thermal insulation core material is fire-resistant fiber cotton.

[0053] It should be noted that the insulation core material is refractory fiber cotton (thermal insulation cotton). The refractory fiber cotton is loose and soft under high and low temperature conditions, has good elasticity, good thermal stability, small shrinkage under high and low temperature conditions, good thermal insulation performance, low thermal conductivity, good chemical stability, corrosion resistance, thermal shock resistance, certain sound absorption performance, easy installation and maintenance, and high reliability.

[0054] The outer surface material is military green waterproof tent cloth, and the base fabric is PVC double-sided calendered mesh cloth (PZ56). The basic properties are shown in Table 3.

[0055] Table 3 Basic performance parameters of waterproof tent fabric

[0056]
