[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0021] The embodiment of the present application discloses a cold chain transportation tray. Refer to Figure 1 , Figure 2 and Figure 3 , including a tray body 1 and a refrigerating top cover 2. A first ventilation cavity 11 is formed inside the tray body 1. A hollow ventilation column 5 with telescopic adjustment is provided in the middle of the top wall of the tray body 1. Support pipes 3 are vertically connected to the four corners of the tray body 1. A second ventilation cavity 21 is provided inside the refrigerating top cover 2. The two ends of the support pipe 3 are respectively inserted and installed with the tray body 1 and the refrigerating top cover 2. The inside of the support pipe 3 is hollow. When the support pipe is connected to the tray body 1 and the refrigerating top cover 2, the first ventilation cavity 11 is communicated with the second ventilation cavity 21 through the support pipe 3. A refrigerating component is provided on the refrigerating top cover 2. A number of heat preservation boards 4 are detachably connected between adjacent two support pipes 3.

[0022] When stacking cold chain goods on the tray body 1, the hollow ventilation column 5 is stretched and fixed, the goods are placed around the hollow ventilation column 5, then the support pipe 3 is installed, the heat preservation boards 4 are filled and installed between the support pipes 3, the refrigerating top cover 2 is installed, and cold air is continuously introduced into the second ventilation cavity 21 through the refrigerating component. The cold air enters the first ventilation cavity 11 through the support pipe 3 and then enters the hollow ventilation column 5, so as to cool the inside of the goods and maintain the freshness of the goods during transportation.

[0023] Specifically, the hollow ventilation column 5 includes a number of sub-pipes 51 sleeved coaxially and slidably and a number of limit pins 52. The sub-pipe 51 with the largest size is fixed on the tray body 1 and extends into the first ventilation cavity 11. A number of first ventilation holes 53 are opened on the outer wall of the sub-pipe 51. The first ventilation holes 53 are densely opened on the outer wall of the sub-pipe 51 with the largest size to enhance the cross-sectional area of the ventilation port between the first ventilation cavity 11 and the inside of the hollow ventilation column 5. An anti-detachment limiting measure is provided between adjacent sub-pipes 51. When the sub-pipes 51 slide relative to each other to stretch the hollow ventilation column 5, the limit pins 52 pass through the first ventilation holes 53 on two sub-pipes 51 at the same time to limit the movement of the sub-pipes 51, so as to limit the hollow ventilation column 5 in the extended state.

[0024] Furthermore, a limiting cavity 12 for accommodating the limiting pin 52 is formed on the tray body 1. The inner wall of the limiting cavity 12 can adopt a rubber or thin-walled plastic accommodating box, and the limiting pin 52 is elastically clamped and connected with the limiting cavity 12. By providing the limiting cavity 12, the limiting pin 52 can be conveniently stored and retrieved, avoiding the loss of the limiting pin 52.

[0025] In the embodiment of the present application, a vertically arranged clamping groove 31 penetrating through both ends is provided on the side wall of the support pipe 3, and a connecting portion adapted to the clamping groove 31 is integrally fixed at the edge of the heat preservation board 4. When installing the heat preservation board 4, the connecting portions at both ends of the heat preservation board 4 are fitted into the clamping groove 31 for installation. Multiple heat preservation boards 4 are sequentially overlapped, and the space between the support pipes 3 can be filled. Dense and small ventilation holes are formed through the heat preservation board 4 to ensure smooth passage of cold air from the refrigerating top cover 2 into the tray.

[0026] In the embodiment of the present application, locking buckles 6 are installed on the outer wall of the support pipe 3 near both ends of the support pipe 3, and buckle rings adapted to the locking buckles 6 are provided on both the tray base and the refrigerating top cover 2. After the support pipe 3, the heat preservation board 4, and the refrigerating top cover 2 are all installed on the tray base, they are connected into a whole through the locking buckles 6, increasing the stability of the overall structure.

[0027] Furthermore, a bottom plate 13 is clamped and installed at the bottom of the tray body 1, and a second ventilation cavity 21 is formed inside the tray body 1 after installing the bottom plate 13. The tray body 1, the bottom plate 13, the refrigerating top cover 2, and the support pipe 3 are all provided with heat preservation materials to ensure the heat preservation performance in the first ventilation cavity 11, the second ventilation cavity 21, and the support pipe 3. By removing the bottom plate 13 on the tray body 1, the accumulated water and the like infiltrating into the second ventilation cavity can be cleaned.

[0028] Furthermore, a plurality of second ventilation holes 14 communicating with the first ventilation cavity 11 are formed at the top of the tray body 1, a plurality of third ventilation holes 22 communicating with the second ventilation cavity 21 are formed on the bottom wall of the refrigerating top cover 2, the refrigerating assembly includes a refrigerating sheet 23 and a ventilation fan 24, an air inlet 25 communicating with the second ventilation cavity 21 is formed on the refrigerating top cover 2, the refrigerating sheets 23 are arranged at intervals in the second ventilation cavity 21, and an air supply channel connecting the air inlet 25 and each support pipe 3 is formed through the refrigerating sheets 23, and the ventilation fan 24 is arranged in the air inlet 25.

[0029] Blow air into the second ventilation cavity 21 through the ventilation fan 24. The refrigeration sheet 23 is externally connected to a refrigerant, and the refrigerant can be a refrigerating liquid. The refrigerating liquid passes through the cold air flow channel inside the refrigeration sheet 23. When the air passes between the refrigeration sheets 23, heat exchange occurs between the air and the refrigeration sheets 23, so as to blow cold air downward. By arranging the refrigeration sheets 23 staggered in the second ventilation cavity 21, the contact area between the air and the refrigeration sheets 23 during the flow of the air towards the support tube 3 in the second ventilation cavity 21 can be increased, and the heat exchange efficiency can be improved. At the same time, through the second ventilation holes 14 on the tray body 1 and the third ventilation holes 22 on the refrigeration top cover 2, cold air is blown in from above and below the goods at the same time, improving the refrigeration effect.
