[0021] S2. After the movable cover is opened, fresh food can be placed in the shell, and then the rotating brackets on both sides are returned to their original positions, and then ice cubes are placed in the ice storage chamber and above the rotating brackets, and then the limit brackets can be retracted, and then the movable cover is slowly closed. Without the push of the push plate, under the action of the first compression spring, the clamping plates on both sides will gradually approach to clamp and fix the fresh food or the packaging box containing the fresh food placed inside, so as to avoid shaking and collision during transportation to cause damage to the food. Then the shell with the fresh food placed can be transported to the transport vehicle and stacked neatly in sequence through the stacking grooves;

[0025] In the present invention, the food inside the storage box can be fixed to avoid collision inside. At the same time, the fixation can be released when the movable cover is opened, and fixed again when the movable cover is closed, so that the items inside can be stored and retrieved conveniently. When in use, the two movable covers are first opened, and the two movable covers will drive the push plates on both sides to rotate. The push plates will push the sliders to rise during the movement. The rise of the slider will drive the traction rope to move and simultaneously drive the two clamping plates to separate. After that, the fixing screws can be removed, the limiting brackets can be slid out and against the movable covers, and then the fixing screws can be screwed into the corresponding threaded holes to limit the movable covers and the clamping plates to keep them still. Then the rotating brackets on both sides can be rotated. , and fix it with the magnet to avoid it blocking the entry of items; when the movable cover is opened, fresh food can be placed in the shell, and then the rotating brackets on both sides are returned to their original positions, and then ice cubes are placed in the ice storage chamber and above the rotating brackets, and then the limit brackets can be retracted, and then the movable cover is slowly closed, and the push of the push plate is lost. Under the action of the first compression spring, the clamping plates on both sides will gradually approach to clamp and fix the fresh food or the packaging box containing the fresh food placed inside, which can avoid shaking and collision during transportation to cause damage to the food, and then the shell with the fresh food placed can be transported to the transport vehicle and stacked neatly in sequence through the stacking grooves;

[0026] In the present invention, ice cubes can be added through the connecting hole during transportation, and there is no need to open the movable cover, which can avoid a large amount of loss of cold air inside the box body, and is easy to use. During transportation, the ice cubes in the ice storage chamber and the rotating bracket will keep the temperature in the shell within a low range, which can prevent the fresh food from spoiling, and the water after the ice cubes melt will be collected in the water storage bin, so that the food can avoid contact with the water source, and it can be suitable for the transportation of various fresh foods; when the temperature in the transportation compartment is high and the ice cubes are consumed too quickly, the sealing block can be slid to add ice cubes to the ice storage chamber through the connecting hole, so that the normal storage of fresh food in the shell can be guaranteed;

[0027] In the present invention, the water in the water storage bin can be quickly and conveniently discharged, which can avoid affecting the storage of fresh food inside. After the transportation is completed, the valve can be opened to discharge the water inside the water storage bin through the drain pipe, which can avoid the accumulation and deterioration of water sources and affect the subsequent storage of fresh food.

[0028] In the present invention, the food inside the storage box can be fixed to avoid collision inside. At the same time, the fixation can be released when the movable cover is opened, and fixed again when the movable cover is closed, so that the internal items can be stored and retrieved conveniently. Ice cubes can be added through the connecting hole during transportation without opening the movable cover, which can avoid a large amount of loss of cold air inside the box. The water in the water storage bin can also be quickly and conveniently discharged to avoid affecting the storage of fresh food inside, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS

7. The usage method of a transportation device based on fresh food cold chain storage according to claim 6, characterized in that, Including the following steps: S1. When in use, first open the two movable covers (2). The two movable covers (2) will drive the push plates (4) on both sides to rotate. During the movement of the push plates (4), the sliders (11) will be pushed to rise. The rising of the sliders (11) will drive the traction ropes (10) to move, and at the same time drive the two clamping plates (26) to separate. Then, the fixing screws (8) can be removed, the limit brackets (7) can be slid out and abutted against the movable covers (2), and then the fixing screws (8) can be screwed into the corresponding threaded holes to limit the movable covers (2) and the clamping plates (26) to keep them stationary. Then, the rotating brackets (22) on both sides can be rotated and adsorbed and fixed to the magnets (25) to avoid hindering the placement of items. S2. After the movable lid (2) is opened, fresh food can be placed into the outer shell (1). Then, the rotating brackets (22) on both sides are put back to their original positions. Next, ice cubes are placed into the ice storage chamber (19) and above the rotating brackets (22). After that, the limit bracket (7) can be retracted. Then, the movable lid (2) is slowly closed. Without the push of the push plate (4), under the action of the first compression spring (28), the clamping plates (26) on both sides will gradually approach each other to clamp and fix the fresh food placed inside or the food packaging box containing fresh food, which can prevent the food from being damaged due to shaking and collision during transportation. Then, the outer shell (1) containing the placed fresh food can be transported onto the transport vehicle and stacked neatly in sequence through the stacking grooves (6). S3. During transportation, the ice cubes in the ice storage chamber (19) and the rotating brackets (22) keep the temperature in the outer shell (1) within a relatively low range, which can prevent the fresh food from spoiling. Moreover, the water melted from the ice cubes is collected in the water storage bin (18), and the food can avoid contacting the water source, which is applicable to the transportation of various fresh foods. When the temperature in the transport vehicle is relatively high and the ice cubes are consumed too quickly, the sealing block (31) can be slid to supplement ice cubes into the ice storage chamber (19) through the communication hole (30), which can ensure the normal storage of the fresh food in the outer shell (1). S4. After the transportation is completed, the valve (21) can be opened to drain the water inside the water storage bin (18) through the drain pipe (20) to prevent the accumulation and spoilage of the water source, which may affect the storage of subsequent fresh food.
