Description

Technical Field

[0001] The present invention relates to the field of transport boxes, and in particular to a long-distance cold chain logistics transport box with a freshness-preserving function. Background Art

[0002] During cold chain logistics transportation, in order to ensure the quality of fresh products, bulk ice cubes or ice bags are usually added to the transport box for preservation. Although adding bulk ice cubes can fill the gaps between fresh products and will not take up too much space, the bulk ice cubes will melt, and the liquid produced by the melting will soak into the fresh products, causing the quality of the fresh products to deteriorate. Although the added ice bags will not flow onto the fresh products after melting, most ice bags are square and large in size, making it difficult to fit into the gaps between fresh products. Instead, they will take up space in the transport box, resulting in the need for more transport boxes to transport fresh products, increasing transportation costs. Summary of the invention

When the cold air passes through the connecting pipe, the cold air is guided and diverted by the diversion pipe, so that part of the cold air is discharged into the middle of the storage cavity through the third air outlet groove, that is, the middle of the stacked fresh-keeping products, so that the fresh-keeping products in the storage cavity can absorb the cold air more evenly, thereby improving the fresh-keeping effect. When workers pack seafood, they push the sliding pipe upwards through the spring telescopic rod to connect the connection port with the corresponding drainage groove, so that the excess water carried by the seafood is discharged into the drainage cavity through the connection block, the drainage pipe and the sliding pipe, and finally discharged from the box through the drainage port, so as to reduce the weight of the box, avoid a large amount of water in the box, and prevent the fresh-keeping products from being continuously soaked in seawater during subsequent transportation, resulting in the deterioration of the quality of the seafood; After the seafood is packed, the box body and the cover are connected and locked. At this time, the sliding tube is squeezed downward by the pressing block so that the connecting port is no longer connected to the corresponding drainage groove, avoiding the cross-flow of cold air in each storage cavity, causing the seafood in each storage cavity to have a cross-flavor and affecting the quality of the seafood.

[0015] The present invention also has the following beneficial effects: The filter net prevents seafood residues from entering the drain tank and affecting the drainage effect of the drain tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Two slots 1006 are provided on the lower side of the housing 1 .

[0023] It also includes a first sealing ring 107 ; each connecting sleeve 104 is provided with a first sealing ring 107 , and the first sealing ring 107 is made of fluororubber.

[0024] The working principle of the above embodiment is as follows: In the initial state, if Figure 2 As shown: three partitions 101 are installed in the box body 1, and a storage cavity 1001 is formed between two adjacent partitions 101, a storage cavity 1001 is formed between the uppermost partition 101 and the cover plate 2, and a miscellaneous cavity 1002 is formed between the lowermost partition 101 and the bottom of the box body 1; and in the initial state, the connecting pipe 103 on each partition 101 is inserted into the connecting sleeve 104 on the lower side of the corresponding partition 101 or the cover plate 2, and the second square groove 10101 in each partition 101 is connected with the first square groove 2001 on the cover plate 2 and the air intake pipe 3 through the connecting pipe 103; when the workers need to pack the fresh-keeping products, they only need to remove the cover plate 2, then hold the connecting pipe 103, pull up and remove each partition 101, leaving only the bottom partition 101, and then the workers pack the fresh-keeping products layer by layer; when packing, the workers can pull out With the air fan 109 as a reference, the loading height of each layer of fresh-keeping products cannot exceed the height of the exhaust fan 109 in the corresponding storage cavity 1001. Therefore, when the loading height of the fresh-keeping products is about to exceed the height of the exhaust fan 109 in the corresponding storage cavity 1001, the worker needs to put the corresponding partition 101 into the box body 1 for separation; therefore, after the fresh-keeping products are packed, there will be a gap between each layer of fresh-keeping products and the partition 101 above it, which is conducive to the entry of cold air into the storage cavity 1001 to cool down and preserve the fresh-keeping products. At the same time, the partition 101 above the corresponding storage cavity 1001 is supported by the connecting pipe 103, and the worker does not need to fix the partition 101 through other locking structures. Therefore, during the loading and unloading process, the worker only needs to hold the connecting pipe 103 to easily remove and install the partition 101, which greatly improves the work efficiency; After the fresh-keeping products are packed, the workers need to transport the box 1 to the refrigeration truck by forklift. It should be noted that two slots 1006 are provided on the lower side of the box 1 for easy insertion of the forklift, so as to facilitate the forklift to transfer the box 1; after the transport box is placed in the refrigeration truck, the worker connects the air inlet pipe 3 on the cover plate 2 to the refrigeration system of the refrigeration truck, and then inputs cold air into the box 1 through the refrigeration system of the refrigeration truck, and the left and right sides of the air inlet pipe 3 are provided with connecting parts, so the air inlet pipes 3 of all the transport boxes can be connected through the connecting parts, which is convenient for the workers to connect all the transport boxes to the refrigeration system of the refrigeration truck; after the air inlet pipe 3 is connected to the refrigeration system of the refrigeration truck, the cold air is input into the box 1 through the refrigeration system of the refrigeration truck. The air pipe 3 enters the first square groove 2001 on the cover plate 2, and then enters the second square groove 10101 in each partition 101 in turn through the connecting pipe 103 and the connecting sleeve 104, and inputs cold air into each storage cavity 1001 through the first air outlet groove 2002 and the second air outlet groove 10102, so as to freeze and preserve the fresh-keeping products in each storage cavity 1001; and when the cold air passes through the connecting pipe 103, the cold air is guided and diverted through the diversion pipe 106, so that part of the cold air is discharged into the middle of the storage cavity 1001 through the third air outlet groove 10301, that is, the middle of the stacked fresh-keeping products, so as to improve the fresh-keeping effect, and the third air outlet groove 1030 1 is provided with a protective cover 105 on the outside, so as to shield the fresh-keeping products when loading them, so as to prevent the fresh-keeping products from piling up at the third air outlet slot 10301 and blocking the third air outlet slot 10301; at the same time, there is a gap between the protective cover 105 and the third air outlet slot 10301, so that the cold air can be better discharged through the third air outlet slot 10301 and discharged to the fresh-keeping products through the through holes on the protective cover 105; it should be noted here that the bottom of the box body 1 is a miscellaneous cavity 1002, so the lower side of the lowest partition 101 is not provided with a second air outlet slot 10102; during transportation, the exhaust fan 109 in each storage cavity 1001 will The air in each storage cavity 1001 is evacuated and discharged into the impurity discharge cavity 1002 through the exhaust slot 1005, and finally discharged from the box body 1 through the exhaust fan 108, and finally the cold air is circulated in the box body 1 through the refrigeration system of the refrigerated truck; thereby, the preservation effect of the fresh-keeping products is improved by the circulating cold air; the problem that when adding bulk ice cubes to the transport box for preservation during the existing cold chain material transportation, the liquid produced by the melting of the bulk ice cubes will soak into the fresh-keeping products, resulting in a decrease in the quality of the fresh-keeping products, and adding ice bags will occupy the space of the transport box, resulting in the need for more transport boxes for the transportation of fresh-keeping products, which increases the transportation cost.

[0025] According to the above working principle, we know that the present invention has the following effects: The air intake pipe 3 is connected to the refrigeration system of the refrigeration truck, and the cold air is circulated in the box body 1 through the air intake pipe 3, the connecting pipe 103, the connecting sleeve 104, the exhaust assembly and the refrigeration system of the refrigeration truck, and the fresh-keeping effect is improved by the circulating cold air; the disadvantage of the prior art that when ice cubes are added for fresh-keeping, the liquid produced by the melting of bulk ice cubes will soak on the fresh-keeping products, resulting in the quality of the fresh-keeping products being reduced, and the addition of ice bags will occupy the space of the transport box, resulting in the fresh-keeping products needing more transport boxes for transportation, which increases the transportation cost; Each partition 101 is connected by a connecting tube 103 and a connecting sleeve 104. At the same time, the upper partition 101 is supported by the connecting tube 103. Workers do not need to fix the partition 101 by other locking structures. Therefore, workers can easily remove the partition 101 during loading and unloading, which greatly improves work efficiency. When the cold air passes through the connecting tube 103, the cold air is guided and diverted by the diversion tube 106, so that part of the cold air is discharged into the middle of the storage cavity 1001 through the third air outlet groove 10301, that is, the middle of the stacked fresh-keeping products, so that the fresh-keeping products in the storage cavity 1001 can absorb the cold air more evenly, thereby improving the preservation effect.

[0026] On the basis of the above technical effects, the present invention also has the following advantages: The first sealing ring 107 greatly improves the sealing performance after the connection between the connecting sleeve 104 and the connecting pipe 103 , and the first sealing ring 107 is made of fluororubber and can be used normally in a low temperature environment.

[0027] Example 2 On the basis of Example 1, Figure 3 and Figure 9-Figure 14 As shown, it also includes a connecting block 201, a drain pipe 202 and a closing component; each partition 101 is fixedly connected to a connecting block 201 on the front and rear sides, and each slider 102 is fixedly connected to the corresponding connecting block 201; each connecting block 201 is provided with a drain groove 20101, and the bottom of the drain groove 20101 is lower than the water inlet of the connecting block 201; each connecting block 201 is fixedly connected to two drain pipes 202; each drain pipe 202 is connected to the corresponding drain groove 20101; the drain pipes 202 located at corresponding positions on two adjacent connecting blocks 201 are connected to each other, and the lowest drain pipe 202 is connected to the drainage cavity 1002; a closing component is arranged in each drain pipe 202; drain outlets 1003 are provided on the left and right sides of the drainage cavity 1002, and a sealing cover can be detachably connected to each drain outlet 1003.

[0028] The closing assembly includes a sliding tube 204, a lower pressing block 206, a spring telescopic rod 207 and an upper pressing block 208; each drain pipe 202 is slidably connected with a sliding tube 204, and each sliding tube 204 passes through the connecting block 201; a connecting port 20401 is provided on the lower side of each sliding tube 204; four lower pressing blocks 206 are fixedly connected to the lower side of the cover plate 2; four spring telescopic rods 207 are fixedly connected to the drainage cavity 1002; an upper pressing block 208 is fixedly connected to the upper side of each spring telescopic rod 207, and each upper pressing block 208 is a hollow structure; each upper pressing block 208 is in contact with the corresponding sliding tube 204.

[0029] The upper surface of each partition 101 is arranged to be inclined with a high middle portion and low front and rear sides.

[0030] It also includes a second sealing ring 203; a second sealing ring 203 is disposed on the upper side of each drain pipe 202, and the second sealing ring 203 is made of fluororubber.

[0031] A filter screen 205 is also included; a filter screen 205 is provided at the water inlet of each connection block 201 .

[0032] The working principle of the above embodiment is as follows: When the transport box is used to transport some seafood, when the workers transfer the seafood into the box body 1, the seafood carries a large amount of moisture, which causes the seafood to be continuously soaked in seawater during subsequent transportation, resulting in a decrease in the quality of the seafood.

[0033] Therefore, Figure 3 and Figure 9-11As shown: in the initial state, three partitions 101 are installed in the box body 1. At this time, the upper and lower adjacent drainage pipes 202 and the sliding pipe 204 are all interconnected. The lowest sliding pipe 204 is connected to the drainage chamber 1002, and the spring telescopic rod 207 is in an extended state. The upper pressing block 208 is pushed upward, thereby pushing the corresponding sliding pipe 204 on the lowest partition 101 upward, and then pushing each correspondingly connected sliding pipe 204 upward, so that the connecting port 20401 is connected with the corresponding drainage groove 20101. Therefore, when the seafood is packed, the excess water carried by the seafood will flow into the drainage groove 20101 along the partition 101 with a high middle part and low front and rear sides on the upper surface, and be discharged into the drainage chamber 1002 through the interconnected sliding pipes 204, and then Workers can open the sealing cover at the drain port 1003 to drain the water in the drainage chamber 1002. In this way, the excess water carried by the seafood can be drained when the workers load it, thereby reducing the weight of the box 1 and avoiding a large amount of water in the box 1, which causes the seafood to be continuously soaked in seawater during subsequent transportation, resulting in a decrease in the quality of the seafood. The drain pipe 202 can also be used as a support rod between the partitions 101 to improve the stability of the partitions 101 and the supporting effect. When the seafood is packed, the worker can check the drainage situation of the drain port 1003. When the drain port 1003 does not drain water or only indirectly discharges a small amount of water, it means that the water in the box 1 is basically emptied. At this time, the worker can cover the sealing cover at the drain port 1003 and connect and lock the box 1 and the cover plate 2. Figure 12-14 As shown: the pressing block 206 on the lower side of the cover plate 2 will be inserted into the drain pipe 202 of the top connecting block 201, and squeeze the sliding tube 204 in the top drain pipe 202 downward, and then squeeze the corresponding connected sliding tubes 204 downward. At this time, the spring telescopic rod 207 is pressed downward, and the sliding tube 204 moves downward, and the connecting port 20401 is no longer connected with the corresponding drain groove 20101; therefore, when cold air is subsequently input into the box body 1, the sliding tube 204 is in a sealed state, and the cold air cannot pass through the sliding tube 204 into other storage chambers 1001, so as to avoid the cold air from flowing through each storage chamber 1001, causing the seafood in each storage chamber 1001 to have a mixed taste, thereby affecting the quality of the seafood.

[0034] Considering that, although the excess water carried by the seafood can be drained away during the seafood packing process, it is impossible to ensure that all the water on the seafood is drained away, therefore, during the transportation, the water generated in the storage cavity 1001 will flow into the drainage groove 20101, and then the water generated in the storage cavity 1001 during the transportation will be collected through the drainage groove 20101, so as to avoid the fresh-keeping products being soaked in water, which will lead to the deterioration of the quality of the fresh-keeping products.

[0035] According to the above working principle, we know that the present invention has the following effects: When workers pack seafood, they push the sliding tube 204 upwards through the spring telescopic rod 207 to connect the connection port 20401 with the corresponding drainage groove 20101, so that the excess water carried by the seafood is discharged into the drainage cavity 1002 through the connection block 201, the drainage pipe 202 and the sliding tube 204, and finally discharged from the box body 1 through the drainage port 1003, so as to reduce the weight of the box body 1, avoid a large amount of water in the box body 1, and prevent the fresh-keeping products from being continuously immersed in seawater during the subsequent transportation, resulting in the deterioration of the quality of the seafood; After the seafood is packed, the box body 1 and the cover plate 2 are connected and locked. At this time, the sliding tube 204 is pressed downward by the pressing block 206 so that the connecting port 20401 is no longer connected to the corresponding drainage groove 20101, thereby preventing cold air from flowing through each storage cavity 1001, causing the seafood in each storage cavity 1001 to have a mixed taste and affect the quality of the seafood.

[0036] On the basis of the above technical effects, the present invention also has the following advantages: The second sealing ring 203 greatly improves the sealing performance after the drain pipe 202 is connected to the corresponding sliding pipe 204, and the second sealing ring 203 is made of fluororubber and can be used normally in a low temperature environment; The filter net 205 is used to prevent seafood residues from entering the drainage trough 20101 and affecting the drainage effect of the drainage trough 20101.

[0037] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
