Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] However, the process of traditional ice emitting cold air over a long period of time can easily lead to uneven temperature distribution inside the transport box, affecting the preservation effect. At the same time, the melting of ice will create additional moisture, which may have adverse effects on some sensitive agricultural products, such as causing rot or changes in texture, thus affecting the final quality of the agricultural products.

[0027] In view of this, the present invention provides a logistics transfer box for cold chain preservation of agricultural products, which has the following beneficial effects: This logistics transfer box for cold chain preservation of agricultural products achieves low-temperature preservation by incorporating a refrigeration mechanism within the lid. Specifically, the inner liner and the cavity together form an ice pack storage space. Users can place ice packs into the inner liner for cooling, and the cooled air is transferred to the inside of the box through pipes to ensure the freshness of agricultural products. Simultaneously, the sealing component effectively seals the cavity, ensuring the cooling effect, thereby achieving cold chain preservation of agricultural products and significantly improving the preservation effect and quality during logistics and transportation. Compared to traditional ice blocks, this method avoids the problem of uneven temperature distribution caused by ice blocks emitting cold air over a long period, and also prevents the generation of additional moisture after the ice blocks melt, avoiding adverse effects such as rotting or changes in texture of sensitive agricultural products, thus effectively ensuring the final quality of the agricultural products.

[0028] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0029] Example 1: By Figure 1-5 It is known that a logistics transfer box for cold chain preservation of agricultural products includes a box body 1. The top of the box body 1 is rotatably connected to a cover 2 via a pin. The inner wall of the cover 2 is provided with a refrigeration mechanism 3. The refrigeration mechanism 3 includes: an inner liner 31, which is disposed inside the cover 2; a cavity 32, which is opened inside the inner liner 31; a pipe 33, which communicates with the inside of the cavity 32 and penetrates through the bottom of the inner liner 31; and a sealing component 34, which is disposed on the front of the cavity 32. Ice packs can be placed inside the inner liner 31 through the cavity 32, and cold air is transferred to the inside of the box body 1 through the pipe 33. The cavity 32 is sealed by the sealing component 34.

[0030] In the specific implementation process, it is worth noting that the refrigeration mechanism 3 set inside the cover 2 achieves the effect of low-temperature preservation. Specifically, the inner liner 31 and the cavity 32 together form an ice pack storage space. Users can put ice packs into the inner liner 31 to cool them. The cooled air is transferred to the inside of the box 1 through the pipe 33, thereby ensuring the freshness of agricultural products. At the same time, the sealing component 34 can effectively seal the cavity 32 to ensure the cooling effect, thereby achieving cold chain preservation of agricultural products and improving the preservation effect and quality during logistics and transportation.

[0031] Furthermore, the sealing assembly 34 includes: a sealing plug 341 disposed on the front side of the cavity 32; a rubber gasket 342 fixedly connected to the outer wall of the sealing plug 341; and a limiting block 343 fixedly connected to both sides of the outer wall of the sealing plug 341; wherein, through the cooperation of the sealing plug 341, the rubber gasket 342 and the limiting block 343, the cavity 32 can be sealed.

[0032] In the specific implementation process, it is worth noting that the cavity 32 can be effectively sealed through the synergistic action of the sealing plug 341, the rubber gasket 342, and the limiting block 343. Specifically, the sealing plug 341 is located on the front of the cavity 32, and its outer wall is fixedly connected with the rubber gasket 342, which further enhances the sealing performance; while the limiting blocks 343 fixed on both sides play a role in positioning and stabilizing, ensuring that the sealing plug 341 is accurately positioned in the cavity 32, thereby achieving the reliability and durability of the sealing effect.

[0033] Furthermore, a protective layer 10 is inserted into the inner wall of the box 1, a second insulation layer 11 is fixedly connected to the inner wall of the protective layer 10, a buffer layer 12 is fixedly connected to the inner wall of the second insulation layer 11, and several partitions 4 are fixedly connected to the inner wall of the buffer layer 12.

[0034] In the specific implementation process, it is worth noting that the protective layer 10 is assembled by a sliding snap-fit ​​method. A second insulation layer 11 is fixedly installed on the inner wall of the protective layer 10. A buffer layer 12 is then fixedly connected to the inner wall of the second insulation layer 11. Multiple partitions 4 are fixedly connected to the inner wall of the buffer layer 12. This structural design effectively improves the insulation and buffering performance of the internal environment of the enclosure 1, reducing the impact of external temperature fluctuations on the internal environment. Simultaneously, the multiple partitions 4 divide the internal space of the enclosure 1 into multiple areas, further enhancing the overall heat insulation effect and space utilization, providing more stable storage conditions for the items inside the enclosure 1. The material of the protective layer 10 is... Plastic materials such as polyimide and polycarbonate have the advantages of being lightweight, corrosion-resistant, and not easily damaged. The second insulation layer 11 and the first insulation layer 5 are made of polystyrene foam (EPS). EPS is a lightweight material with good thermal insulation properties and relatively low cost, making it suitable for cost-sensitive cold chain transportation applications. The closed-cell structure of EPS can prevent heat conduction. Although its thermal conductivity is slightly higher than that of polyurethane foam, it still meets the basic cold chain insulation requirements. EPS is also easy to process and mold, and can be designed and cut according to the internal structure of the container, making installation convenient. The cushioning layer 12 is made of foam particles, another common cushioning material, which is soft, durable, and environmentally friendly. Foam particles can effectively fill the gaps in the carton, reducing the movement and vibration of goods during transportation.

[0035] Furthermore, a protruding plate 6 is fixedly connected to the top of the outer wall of the cover 2, and a plug rod 8 is inserted into the inner wall of the protruding plate 6. The plug rod 8 penetrates the inner wall of the protruding plate 6, and fixing rings 7 are fixedly connected to both sides of the front top of the box 1.

[0036] In the specific implementation process, it is worth noting that the protruding plate 6 is installed by a fixed connection. The inner wall of the protruding plate 6 is designed with an insertion groove to accommodate and fix the insertion rod 8, allowing the insertion rod 8 to pass through the inner wall of the protruding plate 6. At the same time, a fixing ring 7 for placement or fixation is fixed on both sides of the upper front of the box body 1. The purpose of this design is to ensure that when the cover 2 is installed on the box body 1, the insertion rod 8 is inserted into the fixing ring 7 to achieve a stable fixation between the cover 2 and the box body 1, thereby improving the stability and safety of the overall structure.

[0037] Specifically, when using this cold chain logistics transfer box for agricultural products, the refrigeration mechanism 3 set inside the lid 2 achieves the effect of low-temperature preservation. Specifically, the inner liner 31 and the cavity 32 together form an ice pack storage space. Users can put ice packs into the inner liner 31 for cooling. The cooled air is transferred to the inside of the box 1 through the pipe 33, thereby ensuring the freshness of agricultural products. At the same time, the sealing component 34 can effectively seal the cavity 32 to ensure the cooling effect, thereby achieving cold chain preservation of agricultural products and improving the preservation effect and quality during logistics transfer. Through the synergistic action of the sealing plug 341, rubber gasket 342 and limiting block 343, the cavity 32 can be effectively sealed. Specifically, the sealing plug 341 is located on the front of the cavity 32, and its outer wall is fitted with a rubber gasket 342 by a fixed connection, further enhancing the sealing performance. The fixed limiting blocks 343 on both sides serve to position and stabilize the sealing plug 341, ensuring its accurate position within the cavity 32, thereby achieving reliable and durable sealing. A protective layer 10 is fitted by a sliding snap-fit ​​mechanism. A second insulation layer 11 is fixedly installed on the inner wall of the protective layer 10, and a buffer layer 12 is fixedly connected to the inner wall of the second insulation layer 11. Multiple partitions 4 are fixedly connected to the inner wall of the box 1. This structural design effectively improves the heat insulation and buffering performance of the internal environment of the box 1, reduces the impact of external temperature fluctuations on the internal environment, and divides the internal space of the box 1 into multiple areas by using multiple partitions 4, further enhancing the overall heat insulation effect and space utilization, and providing more stable storage conditions for the items inside the box 1. A protruding plate 6 is installed by a fixed connection method. The inner wall of the protruding plate 6 is designed with an insertion groove to accommodate and fix the insertion rod 8, so that the insertion rod 8 can pass through the inner wall of the protruding plate 6. At the same time, a fixing ring 7 is fixed on both sides of the upper front of the box 1 for placement or fixation. The purpose of this design is to achieve a stable fixation between the cover 2 and the box 1 by inserting the insertion rod 8 into the fixing ring 7 when the cover 2 is installed on the box 1, thereby improving the stability and safety of the overall structure.

[0038] Example 2: From Figure 1 , 2As can be seen from 4, 5, 6 and 7, slots 17 are provided on both the front and back sides of one side of the outer wall of the box 1, and a corresponding card block 9 is fixedly connected to the other side of the box 1.

[0039] In the specific implementation process, it is worth noting that by using the slots 17 opened on both the front and back of one side of the outer wall and the corresponding card blocks 9 fixedly connected to the other side, the left and right positions can be accurately positioned and stably connected when multiple boxes 1 are spliced ​​together, effectively preventing movement or loosening caused by external forces, and ensuring the stability and reliability of the overall structure.

[0040] Furthermore, the outer wall of the inner liner 31 is fixedly connected to the first insulation layer 5, and the outer wall of the first insulation layer 5 is fixedly connected to the cover 2.

[0041] In the specific implementation process, it is worth noting that the outer wall of the inner liner 31, through the first insulation layer 5, can provide good insulation for the internal materials.

[0042] Furthermore, the outer walls of the protective layer 10 are provided with handles 13 on both sides, and the handles 13 are provided with protrusions 14 at the front and back. The inner walls of the box 1 are provided with corresponding holes 15 on both sides of the upper part of the protrusions 14.

[0043] In the specific implementation process, it is worth noting that the hand buckles 13 provided on both sides of the outer wall of the protective layer 10 are convenient for people to disassemble. At the same time, the locking holes 15 opened on both sides of the upper part of the inner wall of the box 1 are used in conjunction with the hand buckles 13 and the protrusions 14 to further enhance the stability and reliability of the protective layer 10 during the handling process and effectively prevent the protective layer 10 from moving inside the box 1.

[0044] Furthermore, a sealing gasket 16 is fixedly connected to the inner wall of the cover 2;

[0045] In the specific implementation process, it is worth noting that the sealing gasket 16 can ensure the airtightness of the box body 1 and the cover body 2;

[0046] Specifically, based on the above embodiment one, by designing slots 17 opened on both the front and back of one side of the outer wall and corresponding locking blocks 9 fixedly connected to the other side, precise positioning and stable connection of the left and right positions can be achieved when multiple boxes 1 are spliced, effectively preventing movement or loosening caused by external forces, and ensuring the stability and reliability of the overall structure. The outer wall of the inner liner 31, through the first insulation layer 5, can provide good insulation for the internal materials.
