[0030] In the embodiment of the utility model, the provision of the rolling wheels 12 can facilitate the dragging of the logistics box 1, making it more convenient and quick to carry.

[0031] In the embodiment of the utility model, by utilizing the embedding boss 13 which is arranged in an octagonal shape and utilizing the inclined surfaces on both sides of the upper and lower ends thereof, the upper end of the embedding boss 13 can open the embedding groove 21, so that the staff can quickly complete the engagement between the embedding boss 13 and the embedding groove 21 by pressing, thereby effectively improving the splicing efficiency.

[0032] In the embodiment of the utility model, the locking plate 143 is slidingly arranged in the sliding groove 14, and can be slid out and inserted into the locking groove 22, so as to ensure that the logistics box 1 is firmly fixed as a whole after splicing, and avoid loosening and causing the logistics box 1 to fall off at the splicing point when in use.

[0033] In the embodiment of the utility model, by utilizing the setting of the lower arc-shaped protrusion 141 and the upper arc-shaped protrusion 142, the wrench seat 144 can be engaged with the protrusion through the arc-shaped groove 145, so that the locking plate 143 can be kept fixed, thereby preventing the locking plate 143 from sliding down due to unexpected vibration and causing the logistics box 1 to become loosened when fixed with the expansion frame 3 or the box cover frame 2.

[0034] The box cover frame 2 is arranged above the logistics box 1, and has embedded grooves 21 on the front and rear sides of its lower end. The embedded groove 21 is T-shaped, and locking grooves 22 are arranged on the left and right sides of its lower end.

A logistics box cover 24 is movably mounted on the upper part, and the lower end of the inner part of the logistics box cover 24 is movably engaged with the limiting protrusion 23.

[0035] In the embodiment of the utility model, by utilizing the setting of the box cover frame 2 and the snap-fit ​​cooperation between the limiting protrusion 23 and the logistics box cover 24, the logistics box cover 24 can be quickly disassembled and assembled, and by utilizing the setting of the embedding groove 21 and the locking groove 22, the connection between the box cover frame 2 and the expansion frame 3 or the logistics box 1 can be facilitated, so that the expanded logistics box 1 can be quickly sealed by the logistics box cover 24.

[0036] The expansion frame 3 is arranged above the logistics box 1, and its upper end is provided with the same embedding boss 13 and sliding groove 14 as the logistics box 1, and the internal structure of the sliding groove 14 is the same as the internal structure of the sliding groove 14 of the logistics box 1; its lower end is provided with the same locking groove 22 and embedding groove 21 as those on the box cover frame 2.

[0037] In the embodiment of the utility model, the expansion frame 3 is utilized and a splicing structure identical to that on the logistics box 1 is arranged thereon, and an embedding groove 21 and a locking groove 22 identical to those on the box cover frame 2 are also arranged, so that the expansion frame 3 can be quickly spliced ​​with the logistics box 1, and the expansion frames 3 can be quickly spliced ​​with each other, and can also be quickly spliced ​​with the box cover frame 2, thereby facilitating the staff to expand the logistics box 1 according to the actual delivery specifications, which can greatly reduce the types of specifications of the logistics box and thus reduce its cost.

[0038] As an expandable logistics box for cold chain transportation of the utility model, the embedding boss 13 is movably embedded in the embedding groove 21, and the locking plate 143 is extended and movably inserted in the locking groove 22; it ensures that the logistics box 1 can be connected to the expansion frame 3 or the box cover frame 2, and the expansion frames 3 can also be quickly connected to each other.

[0039] As an expandable logistics box for cold chain transportation of the utility model, the box cover frame 2 can be directly installed on the logistics box 1, and can also be installed on the expansion frame 3, so that the expanded logistics box 1 can be easily sealed.

[0040] As an expandable logistics box for cold chain transportation of the utility model, there are multiple expansion frames 3, and according to the storage specifications, a corresponding number of expansion frames 3 are stacked and installed on the logistics box 1; the logistics box 1 can be expanded according to actual conditions so that it can meet various specifications of distribution requirements.

[0041] As an expandable logistics box for cold chain transportation of the utility model, a plurality of strip holes 31 are opened on the lower surface of the logistics box 1 and the lower surface of the expansion frame 3, and the plurality of strip holes 31 are evenly distributed; through the strip holes 31, when the logistics box 1 is in use, condensed water generated by the delivered items can be quickly discharged to avoid accumulation and deterioration of the delivered items.

[0042] As an expandable logistics box for cold chain transportation of the utility model, when the wrench seat 144 is clamped on the lower arc-shaped protrusion 141, the locking plate 143 is completely retracted in the sliding groove 14, and when the wrench seat 144 is clamped on the upper arc-shaped protrusion 142, the locking plate 143 extends out of the sliding groove 14; the locking plate 143 can remain fixed after extending or contracting, thereby facilitating the disassembly and assembly of the expansion frame 3 or the box cover frame 2.

[0043] As an expandable logistics box for cold chain transportation of the utility model, when the expansion frame 3 and the logistics box 1 are connected only by the embedding boss 13 and the embedding groove 21, the expansion frame 3 can slide left and right above the logistics box 1, making it more convenient and quick to disassemble the expansion frame 3 or the box cover frame 2, so that the logistics box 1 can be reused.

[0044] When the utility model is used specifically, when the logistics box 1 needs to be used, the staff takes out the corresponding number of expansion frames 3 according to the actual delivery specifications, and then the staff manually places the expansion frame 3 on the top of the logistics box 1 and aligns it with the logistics box 1, and then the staff manually presses the expansion frame 3 downwards, so that the embedding groove 21 on it is stretched open by the squeezing of the embedding boss 13, and then the embedding boss 13 is inserted into the embedding groove 21, and then the staff aligns the expansion frame 3 with the logistics box 1 again, and then the staff manually pushes the wrench seat 144 upwards to disengage it from the lower arc-shaped protrusion 141, and drives the locking plate 143 to extend out of the sliding groove and insert it into the locking groove 22, and moves the wrench seat 144 to the upper arc-shaped protrusion 142, so that the upper arc-shaped protrusion 142 is snapped into the arc-shaped groove 145, and then the wrench seat 144 and the locking plate 143 are fixed, so that the expansion frame 3 and the logistics box 1 are fixed.

[0045] Then the staff can install the remaining expansion frames 3 on the logistics box 1 in sequence according to the above method. When the expansion frames 3 are installed, the staff uses the logistics box 1 to store items. When the items are stored, the staff takes out the box cover frame 2 and installs the box cover frame 2 on the logistics box 1 according to the above method, so that the items are sealed in the logistics box 1.

[0046] When the logistics box 1 is used up and the expansion frame 3 needs to be disassembled for reuse, the staff can manually push the wrench seat 144 downward to remove the wrench seat 144 from the upper arc-shaped protrusion 142 and snap into the lower arc-shaped protrusion 141, and drive the locking plate 143 to move downward and completely retract into the sliding groove 14, thereby completely removing it from the locking groove 22, and then the staff can push the expansion frame 3 to move left and right to remove it from the logistics box 1;

[0047] The disassembled expansion frame 3 may include a box cover frame 2 and multiple expansion frames 3. The staff can separate the box cover frame 2 and multiple expansion frames 3 one by one in the above manner, so that the device can be reused.

[0048] When the device is implemented, the whole device can be made of high-quality PP plastic material to reduce its own gravity, ensure its own strength, and facilitate transportation. At the same time, it can ensure that the device itself will not be damaged when it is spliced ​​multiple times.
