Detailed Embodiment

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0020] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0021] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] A fresh-keeping box, as Figure 2 shown, includes a box body 1. Installation grooves 32 are opened on both opposite side walls of the box body 1. Installation pieces 31 are slidably connected in the installation grooves 32. A cover 33 is rotatably connected to the top of the box body 1. A groove 34 corresponding to the position of the installation piece 31 is opened on the cover 33. When the box bodies 1 are stacked for storage or transportation, the cover 33 can be first covered on the box body 1, and then the box body 1 can be stacked on the cover 33. At this time, the installation piece 31 can slide along the installation groove 32 and thus slide into the corresponding groove 34, preventing the box body 1 from shifting during transportation or storage.

[0023] As Figures 3 - 11As shown, the inside of the box body 1 is partitioned to form an aquatic product area 2 and a fruit and vegetable area 3. A number of fresh-keeping modules 4 are arranged in the fruit and vegetable area 3. A number of partition boards 5 are fixedly connected to the fruit and vegetable area 3. A hanging rack 6 is detachably connected to the top of the partition board 5. A supporting plate 7 is arranged below the hanging rack 6. A space for storing fruits and vegetables is formed between the supporting plate 7 and the fresh-keeping module 4. The partition board 5 divides the fruit and vegetable area 3 into several areas, and fruits and vegetables can be classified and placed in these areas, which is convenient for arranging them neatly and taking them out uniformly for use. The inside of the fresh-keeping module 4 is used to place fruits and vegetables, so as to ensure that the fruits and vegetables can maintain freshness and slow down their deterioration and oxidation. A space for storing fruits and vegetables is formed between the fresh-keeping module 4 and the supporting plate 7, and the supporting plate 7 can squeeze the fruits and vegetables to prevent the internal placement gap of the fruits and vegetables from being too large and causing bouncing damage during transportation. The inner surface of the aquatic product area 2 is detachably connected with a waterproof bag 8. A sealing zipper 9 is arranged at the bag mouth of the waterproof bag 8. An oxygen delivery pipe 10 is connected to the top of the waterproof bag 8. The aquatic product area 2 is used to store aquatic products such as fish and shrimp. The waterproof bag 8 is made of nylon and is relatively strong and durable. The aquatic products are placed in the waterproof bag 8. After loading is completed, oxygen is first injected into the water from the oxygen delivery pipe 10, and then the oxygen delivery pipe 10 can be closed. During transportation, the sealing zipper 9 can improve the sealing effect of the waterproof bag 8, thereby slowing down the loss of oxygen and ensuring that the aquatic products can maintain freshness during transportation.

[0024] In one embodiment, the fresh-keeping module 4 includes an outer membrane 11 and an inner membrane 12. A number of water injection cavities 13 are formed between the outer membrane 11 and the inner membrane 12. The water injection cavities 13 are filled with water-absorbing resin and water. The inner membrane 12 is provided with several layers. A number of cavities 15 are arranged between adjacent two layers of the inner membrane 12. A number of buffer pads 14 are fixedly connected in the cavities 15. Before using the box body 1, the box body 1 can be first placed in a cold storage for freezing and standby. In a low-temperature environment, the water-absorbing resin and water can be frozen, so that the internal environment of the box body 1 can maintain a low temperature during transportation. The buffer pads 14 are arranged between the water injection cavities 13 and the fruits and vegetables, and can prevent the outside of the fruits and vegetables from being knocked, so as to protect the fruits and vegetables. The inner layer surface is flat and is in direct contact with the fruits and vegetables, and can ensure that the fruits and vegetables will not be squeezed abnormally while keeping fresh.

[0025] In one embodiment, the suspension bracket 6 includes a telescopic rod 16 and a mounting plate 17. The mounting plate 17 is detachably connected to the partition plate 5. Two ends of the telescopic rod 16 are respectively connected to the mounting plate 17 and the supporting plate 7. The supporting plate 7 is located below the mounting plate 17. An air extraction hole 18 is formed in the supporting plate 7, and a screw cap is threadedly connected to the air extraction hole 18. The supporting plate 7 includes a bottom plate 19 and a plurality of side plates 20. The bottom plate 19 is fixedly connected to one end of the telescopic rod 16. The air extraction hole 18 is formed in the bottom plate 19. The side plates 20 are slidably connected to the top surface of the bottom plate 19. A sliding groove 21 is formed in the bottom plate 19, and a clamping groove 22 is formed on a side of the sliding groove 21. The side plates 20 are slidably connected in the sliding groove 21. Two sides of the side plates 20 are slidably connected with limiting blocks 23. The limiting blocks 23 are detachably connected to the clamping grooves 22. Through grooves 24 are formed in the side plates 20.

[0026] When loading fruits and vegetables, the fruits and vegetables are placed in the space enclosed by the inner layer. Then, one of the inner layers can be passed through the through groove 24, and the side plate 20 is moved along the sliding groove 21 to make the inner layer snap into the space between the side plate 20 and the bottom plate 19, so that the side of the inner layer can be connected to the side plate 20 and the bottom plate 19. Then, the air between the inner layer and the bottom plate 19 is extracted from the air extraction hole 18. At this time, the bottom plate 19 will pull the telescopic rod 16 to move towards the side of the fruits and vegetables, so that the fruits and vegetables are squeezed by the bottom plate 19, thereby reducing the air between the fruits and vegetables, reducing the respiration, ensuring that the fruits and vegetables can maintain good freshness during transportation, and at the same time reducing the distance between the fruits and vegetables, thereby preventing the fruits and vegetables from shifting and colliding with each other during transportation.

[0027] Further, a buffer plate 25 is arranged below the bottom plate 19. A plurality of springs 26 are arranged between the bottom plate 19 and the buffer plate 25. Two ends of the springs 26 are respectively fixedly connected to the bottom plate 19 and the buffer plate 25. A receiving groove 27 is formed in the bottom of the buffer plate 25, and an elastic net 28 is fixedly connected in the receiving groove 27. During the air extraction process, the buffer plate 25 will first contact the fruits and vegetables. Both the elastic net 28 and the springs 26 can play a buffering role to prevent the fruits and vegetables from being crushed due to too fast air extraction. During transportation, the box body 1 may be jolted. At this time, the springs 26 can be stressed and contracted to reduce the extrusion of the buffer plate 25 on the fruits and vegetables.

[0028] Further, a connecting strip 29 is fixedly connected to the side of the buffer plate 25. One side of the connecting strip 29 away from the buffer plate 25 extends into the waterproof bag 8. One end of the connecting strip 29 close to the waterproof bag 8 is rotatably connected to a moving plate 30. During transportation, the buffer plate 25 will be jolted and move slightly. During the movement, it can drive the connecting strip 29 to move. The connecting strip 29 is connected from the fruit and vegetable area 3 to the aquatic product area 2 and has a relatively long length. Therefore, a small movement of the connecting strip 29 near the buffer plate 25 can be transmitted into a larger jitter on the side close to the moving plate 30, thereby causing the moving plate 30 to rotate. The water in the aquatic product area 2 can be stirred by the moving plate 30 to form flowing water, improving the survival rate of aquatic products.

[0029] A cold chain transport vehicle, as Figure 1 and Figure 2 shown, for transporting fresh-keeping boxes, including a vehicle head 35 and a carriage 36. The vehicle head 35 is connected to the carriage 36. A tail plate 37 is rotatably connected to one side of the carriage 36 away from the vehicle head 35. A moving groove 38 is formed in the inner bottom surface of the carriage 36. The width of the moving groove 38 is the same as that of the mounting piece 31. An extension groove 39 is provided on one side of the moving groove 38 close to the tail plate 37. The width of the extension groove 39 gradually increases from the moving groove 38 to the tail plate 37. Before transportation, the box body 1 needs to be loaded. During the loading process, a forklift can be used to lift the box body 1. At this time, the mounting piece 31 will slide along the mounting groove 32 and can protrude from the box body 1. When placing it in the carriage 36, the mounting piece 31 can first fall into the extension groove 39. The width of the extension groove 39 is greater than the width of the mounting piece 31. Therefore, it is relatively easy to align the mounting piece 31 with the extension groove 39. Then, the box body 1 can be pushed to make the box body 1 slide along the extension groove 39 and the moving groove 38 to position the placement of the box body 1. At the same time, it can also prevent the box body 1 from sliding during transportation, improving the stability.

[0030] The usage method of the present invention is as follows: Before using the box body 1, the box body 1 can be placed in a cold storage for freezing and standby. In a low-temperature environment, the water-absorbing resin and water can be frozen, enabling the internal environment of the box body 1 to remain at a low temperature during transportation. When in use, fruits and vegetables are placed in the space enclosed by the inner layer. The buffer plate 25 is pressed downward to make the buffer plate 25 contact the fruits and vegetables. Then, the inner layer is pulled to make the inner layer pass through the through groove 24. At the same time, the side plate 20 is slid to make the inner layer snap into the space between the side plate 20 and the bottom plate 19, enabling the side of the inner layer to be connected to the side plate 20 and the bottom plate 19. Then, the air between the inner layer and the bottom plate 19 is pumped out from the air extraction hole 18. At this time, the bottom plate 19 will pull the telescopic rod 16 to move towards the fruits and vegetables, thereby squeezing the fruits and vegetables by the bottom plate 19, reducing the air between the fruits and vegetables, and reducing the respiration.

[0031] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
