The groove and the two adjacent L-shaped grooves are mutually connected. A movable L-shaped rod 16 is provided in the L-shaped groove, and two connecting rods are provided at the top of the movable L-shaped rod 16. A hole is provided in each of the connection holes, and a spring 41 is fixedly connected in each of the connection holes. The top of the spring 41 is fixedly connected to the adjacent side wall of the L-shaped groove. An air bag 17 is provided in the slot.

[0040] The outer edges of the connection frame 1 are fixedly connected with the second U-shaped plate 11 near the top, and the left and right sides of the sealing frame 7 are fixedly connected with the first U-shaped plate 8 near the bottom. The outer edges of the two connection frames 1, the U-shaped frame 2 and the sealing frame 7 are collectively sleeved with a sealing strip 12. The sealing strip 12 has two connecting grooves. A Velcro hairy surface 39 is fixedly connected in the left connecting groove, and a Velcro thorny surface 38 is fixedly connected in the right connecting groove. The Velcro hairy surface 39 and the Velcro thorny surface 38 are arranged to fit each other.

[0041] When it is necessary to store and transport fresh and perishable goods, the L-shaped plate 15 is taken out, and the fresh and perishable goods are placed inside the two connecting frames 1 and the U-shaped frame 2, and the refrigerator 14 is started. The refrigerator 14 can improve the freshness of the fresh and perishable goods. The sealing frame 7 and the sealing strip 12 can seal the cold air emitted by the refrigerator 14. When it is necessary to store and transport large-volume goods, the sealing frame 7 is taken out, and the L-shaped plate 15 is replaced on the top of the refrigerator 14. The connecting frame 1 and the U-shaped frame 2 can be adjusted to the size of the large-volume goods, thereby improving the applicability of the device. When the device is transported on a ship, if the device accidentally falls into the water, the two air bags 17 at the bottom of the device can make the device float on the water for a short time, providing personnel with time to salvage it.

[0042] Working principle: This device can be used as an independent transport device, and can also be used as an auxiliary storage device for other transport devices. Before this, when the device stores supply chain management goods, different storage methods will be required for different goods. When storing and placing fresh and perishable goods, the operator first removes the lock 37 from the second limit plate 36, adjusts the swing plate 35, moves the swing plate 35 away from the second limit plate 36, pulls the first connecting frame 1 on the left and right sides, and the first connecting frame 1 on the left and right sides moves away from the U-shaped frame 2. The first connecting frame 1 drives the elastic rope 13 to stretch. After the first connecting frame 1 moves away from the U-shaped frame 2, the L-shaped plate 15 and the slider 40 inside the first connecting frame 1 are moved out of the first connecting frame 1, and then the first connecting frame 1 is released, the first connecting frame 1 and the U-shaped frame 2 are fitted together, and the swing plate 35 is put back on the second limit plate 3 6 surface, buckle the lock 37 again, place the fresh and perishable goods inside the two connecting frames 1 and the U-shaped frame 2, then take out the sealing frame 7, place the sealing frame 7 on the top of the two connecting frames 1 and the U-shaped frame 2, and then take out the sealing strip 12, wrap the sealing strip 12 around the sealing frame 7, the two connecting frames 1 and the surface of the U-shaped frame 2, and the sealing strip 12 is fitted and limited by the Velcro fur-like surface 39 and the Velcro thorn-like surface 38. When the fresh and perishable goods are transported, start the refrigerator 14, and the refrigerator 14 applies cold air to the internal space of the sealing frame 7, the two connecting frames 1 and the U-shaped frame 2, so as to ensure the freshness of the fresh and perishable goods. When it is necessary to limit the sealing frame 7, pull the elastic limiting cloth 5, and the elastic limiting cloth 5 is stretched through the groove on the fixing plate 20, so that one side of the elastic limiting cloth 5 is fitted on the surface of the sealing frame 7, thereby limiting the sealing frame 7;

[0043] When storing and placing large-volume goods, the operator opens the lock 37 and moves it away from the second limiting plate 36, adjusts the swing plate 35, moves the swing plate 35 away from the second limiting plate 36, and places the large-volume goods inside the two connecting frames 1 and the U-shaped frame 2. The length of the large-volume goods may exceed the length of the two connecting frames 1 and the U-shaped frame. At this time, the two connecting frames 1 are pulled, and the connecting frame 1 drives the elastic rope 13 to stretch, and the position of the U-shaped frame 2 remains unchanged, thereby meeting the length of the large-volume goods. When storing and placing large-volume goods, the sealing frame 7 and the sealing strip 12 do not need to be used, and the L-shaped plate 15 does not need to be disassembled. The L-shaped plate 15 can protect the safety of the refrigerator 14. The elastic shielding cloth 3 will be used, and the hooks 6 at the bottom of the elastic shielding cloth 3 will be respectively put into the adjacent fixing rings 10, and the elastic shielding cloth 3 will be wrapped on the surface of the large-volume goods. Then the elastic limiting cloth 5 is pulled, and the elastic limiting cloth 5 further limits the elastic shielding cloth 3 and the large-volume goods to prevent the large-volume goods from falling.

[0044] After the storage and placement of the goods is completed, when the device is used as an independent transportation equipment, there is no need to adjust the position of the rotating disk 27, the universal wheel 29 contacts the ground, and the operator pushes the push handle 4 to drive the device to move and transport. When the device is used as an independent transportation equipment, the device is only transported over a short distance. During this process, one side of the limiting L-shaped rod 23 is always located below the connecting frame 1. When the device is used as an auxiliary storage device in other transportation equipment, the operator moves the device to other transportation equipment, and then rotates the limiting threaded rod 33 to move the limiting threaded rod 33 and the limiting U-shaped rod 32 away from the rotating disk 27. The operator adjusts the rotating disk 27, rotates the rotating disk 27 180 degrees, and rotates the universal wheel 29 The support plate 30 is rotated upward, and the bolt 24 is then rotated to move the bolt 24 away from the limiting L-shaped rod 23 and the fixing tube 22, and one side of the limiting L-shaped rod 23 is moved away from the bottom of the connecting frame 1, so as to ensure that the bottom of the device can stably contact other transportation equipment, thereby ensuring the stability of the device. When the support plate 30 contacts other transportation equipment, the limiting threaded rod 33 is rotated to the inside of the rotating disk 27 and the connecting frame 1 again, and the connecting threaded rod 31 is rotated onto the support plate 30, and one end of the connecting threaded rod 31 is inserted into other transportation equipment, thereby limiting the device and further improving the stability of the device. After that, the connecting U-shaped rod 26 is taken out, and the push handle 4 is taken out, and the installation steps of the device are completed;

[0045] If the device is installed on a ship and accidentally falls into the water, the two air bags 17 at the bottom of the device will support the device to float on the water surface, giving the operator time to salvage it. The inside of the air bag 17 needs to be inflated regularly. The sealing plug 44 is opened, and the inflation cylinder is aimed at the air pipe 43. The gas enters the air bag 17 through the air pipe 43, thereby inflating the air bag 17. The movable L-shaped rod 16, the spring 41 and the connecting rope 42 support and limit the air bag 17.
