Description

Technical Field

[0001] The utility model relates to the technical field of cold chain transportation anti-collision, in particular to a cold chain transportation anti-collision device. Background Art

[0002] In cold chain transportation, refrigerated trucks are often used for land transportation. During the transportation process, the temperature in the cargo compartment is lowered by a refrigerator to cool the goods in the cargo compartment, inhibit the growth of microorganisms in the goods, slow down respiration, and thus achieve the effect of prolonging the preservation of fresh and perishable goods.

[0003] However, the following technical problems exist in the prior art: during cold chain transportation, the carriage may not be full. Therefore, once the goods are transported, they are prone to sway left and right, front and back, inside the carriage, which may easily cause collisions. If fragile items such as vaccines are being transported, unnecessary losses may occur.

[0004] Therefore, a cold chain transportation anti-collision device is needed to improve this problem. Utility Model Content
