Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to an insulated plastic pallet suitable for cold chain logistics. Background Technology

[0002] Cold chain transportation refers to the transportation of goods at a constant temperature throughout the entire process, including loading, unloading, changing transport methods, and replacing packaging equipment, to ensure food quality and reduce spoilage. Cold chain transportation requires forklifts to place goods on pallets, allowing for efficient transport. However, cold chain goods lack protective devices on pallets, making them prone to falling off when stacked, thus failing to provide adequate protection.

[0003] In actual use, existing logistics pallets have a simple structure, making it impossible to refrigerate cold chain goods when placed on them. During loading, unloading, and handling, they are exposed to the outside environment, causing the ice on the surface of the cold chain goods to melt easily. This is not conducive to the long-term transportation and use of cold chain goods, and therefore makes them inconvenient to use. Utility Model Content

[0032] Before use, the cold chain goods are moved to the top of the pallet panel 2. Weight-reducing holes 4 are opened on the surface of the pallet panel 2 to reduce the pallet's weight. A ventilation base plate 1 is provided below the pallet panel 2.

Simultaneously, the front panel 10, which is rotatably connected to one end of the first side plate 8, and the back plate 11, which is rotatably connected to one end of the second side plate 9, are flipped over towards the cold chain goods. The top of the flipped second side plate 9 is then... The top plate 12, with a limiting plate 16 on its outer side, limits the first side plate 8, front panel 10, and back plate 11. The first side plate 8, second side plate 9, front panel 10, top plate 12, and back plate 11 together wrap the cold chain goods placed above the pallet panel 2.
