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-keeping 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, resulting in a decrease in the quality of the fresh products. 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

Workers do not need to use other locking structures to fix the partitions, so they can easily remove the partitions during loading and unloading, greatly improving work efficiency. When the cold air passes through the connecting pipes, 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 chamber 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 chamber can absorb the cold air more evenly, improving the preservation effect.

[0016] When workers are packing seafood, they use the spring telescopic rod to push the sliding tube upwards to connect the connection port with the corresponding drainage trough, so that the excess water carried by the seafood is discharged into the drainage cavity through the connection block, drainage pipe and sliding tube, and finally discharged from the box through the drainage port, thereby reducing the weight of the box, avoiding a large amount of water in the box, and preventing the fresh-keeping products from being continuously soaked in seawater during subsequent transportation, which would lead to the deterioration of the quality of the seafood;

[0017] 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 connection port is no longer connected to the corresponding drainage trough, 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.

[0018] The present invention also has the following beneficial effects:

[0019] The filter net prevents seafood residue from entering the drain tank and affecting the drainage effect of the drain tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Two slots 1006 are provided on the lower side of the box body 1 .

[0042] 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.

[0043] The working principle of the above embodiment is as follows:

[0044] In the initial state, if Figure 2As 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 cover plate 2, and the second square groove 10101 in each partition 101 is connected to the first square groove 2001 on the cover plate 2 and the air intake pipe 3 through the connecting pipe 103; when the worker needs to pack the fresh-keeping products, he only needs 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 worker packs the fresh-keeping products layer by layer; when packing, the worker 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 chamber 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 chamber 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 chamber 1001 to cool and preserve the fresh-keeping products. At the same time, the partition 101 above the corresponding storage chamber 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 reinstall the partition 101, which greatly improves work efficiency.

[0045] After the fresh-keeping products are packed, the workers need to transport the box 1 to the refrigerated truck by forklift. It should be noted that there are two slots 1006 on the lower side of the box 1 for easy insertion of the forklift, so that the forklift can transfer the box 1; after the transport box is placed in the refrigerated truck, the worker connects the air inlet pipe 3 on the cover plate 2 to the refrigeration system of the refrigerated truck, and then inputs cold air into the box 1 through the refrigeration system of the refrigerated 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 transport boxes can be connected through the connecting parts, which is convenient for workers to connect all transport boxes to the refrigeration system of the refrigerated truck; after the air inlet pipe 3 is connected to the refrigeration system of the refrigerated truck, the cold air is input into the box 1 through the refrigeration system of the refrigerated 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 by 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, thereby improving the preservation 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, and 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 second air outlet slot 10102 is not provided on the lower side of the lowest partition 101; during transportation, the exhaust fan 109 in each storage cavity 1001 will The air in each storage cavity 1001 is extracted and discharged into the exhaust cavity 1002 through the exhaust slot 1005, and finally discharged from the box body 1 through the exhaust fan 108. 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; this solves the problem that when bulk ice cubes are added 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 the addition of ice bags will occupy the space of the transport box, resulting in the need for more transport boxes for the fresh-keeping products, which increases the transportation cost.

[0046] According to the above working principle, we know that the present invention has the following effects:

[0047] The air intake pipe 3 is connected to the refrigeration system of the refrigerated 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 refrigerated truck, and the circulating cold air improves the preservation effect. This solves the problem that when ice cubes are added for preservation in the prior art, the liquid produced by the melting of 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 take up space in the transport box, resulting in the need for more transport boxes for the fresh-keeping products, which increases the transportation cost.

[0048] The partitions 101 are connected by connecting tubes 103 and connecting sleeves 104, and the upper partitions 101 are supported by connecting tubes 103. Workers do not need to fix the partitions 101 through other locking structures. Therefore, workers can easily remove the partitions 101 during loading and unloading, which greatly improves work efficiency. When the cold air passes through the connecting tubes 103, the cold air is guided and diverted by the diversion tubes 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.

[0049] On the basis of the above technical effects, the present invention also has the following advantages:

[0050] 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.

[0051] Example 2

[0052] On the basis of Example 1, Figure 3 and Figures 9-14 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 provided 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.

[0053] 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 to 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 fixed to the lower side of the cover plate 2; four spring telescopic rods 207 are fixed to the drainage cavity 1002; an upper pressing block 208 is fixed 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.

[0054] The upper surface of each partition 101 is configured to be inclined with a higher middle portion and lower front and rear sides.

[0055] It also includes a second sealing ring 203; a second sealing ring 203 is provided on the upper side of each drain pipe 202, and the second sealing ring 203 is made of fluororubber.

[0056] A filter screen 205 is also included; a filter screen 205 is provided at the water inlet of each connection block 201 .

[0057] The working principle of the above embodiment is as follows:

[0058] When the transport box is used to transport some seafood, when workers transfer the seafood into the box body 1, the seafood carries a large amount of water; as a result, the seafood is continuously soaked in seawater during subsequent transportation, resulting in a decrease in the quality of the seafood.

[0059] Therefore, Figure 3 and Figures 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 in a state of mutual communication. The lowermost 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 lower partition 101 upward, and then pushing each corresponding connected sliding pipe 204 upward, so that the connecting port 20401 is connected to the corresponding drainage trough 20101. Therefore, when the seafood is packed, the excess water carried by the seafood will flow into the drainage trough 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 The worker 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 away when the worker loads the seafood, thereby reducing the weight of the box body 1 and avoiding a large amount of water in the box body 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 improve 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 body 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 body 1 and the cover plate 2. Figure 12-14 As shown: the downward pressing block 206 on the lower side of the cover plate 2 will be inserted into the drain pipe 202 of the uppermost connecting block 201, and squeeze the sliding tube 204 in the uppermost 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 to 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, thereby avoiding the cold air from flowing through each storage chamber 1001, causing the seafood in each storage chamber 1001 to have a mixed taste, affecting the quality of the seafood.

[0060] 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, the water generated in the storage cavity 1001 during transportation will flow into the drainage groove 20101, and then the water generated in the storage cavity 1001 during transportation will be collected through the drainage groove 20101 to prevent the fresh-keeping products from being soaked in water, which will lead to a decrease in the quality of the fresh-keeping products.

[0061] According to the above working principle, we know that the present invention has the following effects:

[0062] When workers are packing seafood, they push the sliding tube 204 upwards through the spring telescopic rod 207 to connect the connecting 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 connecting block 201, the drainage pipe 202 and the sliding tube 204, and finally discharged from the box body 1 through the drainage port 1003, thereby reducing the weight of the box body 1, avoiding a large amount of water in the box body 1, and preventing the fresh-keeping products from being continuously soaked in seawater during subsequent transportation, which would cause the quality of the seafood to deteriorate.

[0063] 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 squeezed downward by the pressing block 206 so that the connecting port 20401 is no longer connected to the corresponding drainage groove 20101, thereby preventing the 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.

[0064] On the basis of the above technical effects, the present invention also has the following advantages:

[0065] 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 low temperature environment;

[0066] The filter net 205 prevents seafood residue from entering the drainage trough 20101 and affecting the drainage effect of the drainage trough 20101.

[0067] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention.
