For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0027] like Figures 1 to 3As shown, a fresh-keeping box with stable stacking can be interlocked with each other during the stacking and transportation process, has good stacking stability, can prevent the fresh-keeping box from falling due to transportation shaking during transportation and affecting the loaded products, and reduce transportation costs. The fresh-keeping box of this embodiment includes a box body 1 and a box cover 2 covering the top of the box body 1. The fresh products to be transported can be loaded in the box body 1 and sealed by the box cover 2. Among them, the cross-section of the box body 1 of this embodiment is a centrally symmetrical convex polygonal structure, which is convenient for the stacking of the fresh-keeping boxes, and after stacking, the free space can be reduced, thereby improving the space utilization rate. Specifically, the cross-section of the box body 1 of this embodiment has an octagonal structure, including four side wall surfaces and four transition surfaces, and the side wall surfaces and the transition surfaces are alternately connected in sequence, so that when the fresh-keeping boxes of this embodiment are stacked, the side wall surfaces of adjacent fresh-keeping boxes can fit each other, reducing the waste of space and improving the stability after stacking.

[0028] like Figures 1 to 4 As shown, in order to improve the stability of the fresh-keeping boxes when they are stacked and transported, the cross-sectional area of ​​the box body 1 is designed in this embodiment to be a structure that gradually decreases from the top of the box body 1 to the bottom of the box body 1, so that the side walls of the box body 1 gradually gather from top to bottom toward the center of the bottom of the box body 1 to form an inclined surface, so that when the fresh-keeping boxes are stacked, the adjacent fresh-keeping boxes can be stacked one front and one back, so that the side walls of the two adjacent boxes 1 abut against each other, and after the fresh-keeping boxes are stacked, the adjacent fresh-keeping boxes can be mutually limited by the boxes 1 with inclined side walls, thereby improving the stability of the fresh-keeping boxes after stacking, and facilitating smooth transportation. At the same time, when the fresh-keeping boxes are stacked one front and one back, the side walls of the adjacent boxes 1 fit each other, which can also effectively reduce the free gap generated during stacking, which can effectively improve the space utilization rate and improve the transportation efficiency.

[0029] like Figures 1 to 3 As shown, the top circumferential side of the box body 1 of this embodiment is also provided with a protruding snap-in edge 11, and the bottom of the box body 1 is provided with a snap-in step 12 formed by circumferential contraction relative to the side wall of the box body 1. When multiple fresh-keeping boxes are stacked one front and one back for transportation, the snap-in edges 11 of two adjacent fresh-keeping boxes can be embedded in the snap-in steps 12 of the adjacent box body 1, so that when the fresh-keeping boxes are stacked, they can be engaged with each other with the adjacent fresh-keeping boxes under the action of the snap-in steps 12 and the snap-in edges 11, which can further improve the overall stacking stability of the fresh-keeping boxes and prevent the fresh-keeping boxes from falling due to shaking during transportation.

[0030] like Figures 1 to 3As shown, the bottom of the box body 1 of this embodiment is circumferentially contracted relative to the side wall of the box body 1 to form a contraction portion 13, so that when the box body 1 is placed on a plane, a card-engaging space with a certain height can be formed between the side wall of the contraction portion 13 and the card-engaging step 12 and the plane, and the height of the card-engaging space is the same as the thickness of the convex edge formed after the box cover 2 is closed on the top of the body and combined with the card-engaging edge 11. Therefore, when the fresh-keeping boxes are stacked alternately front and back, the convex edges formed by the box covers 2 and the card-engaging edges 11 of two adjacent fresh-keeping boxes can be embedded in the card-engaging space of the adjacent fresh-keeping box, thereby achieving mutual interlocking between the stacked fresh-keeping boxes and improving the stability of the stacking.

[0031] And, if Figure 4 As shown, when multiple layers of fresh-keeping boxes are stacked, the contraction portion 13 at the bottom of the box body 1 of the fresh-keeping box located on the upper layer abuts against the box cover 2 of the lower layer fresh-keeping box longitudinally adjacent thereto. At this time, one side of the box cover 2 of the fresh-keeping box stacked reversely around the upper layer fresh-keeping box is stacked on the edge of the box cover 2 of the fresh-keeping box located on the lower layer. Therefore, when the multiple layers of fresh-keeping boxes are stacked, the force between the upper and lower layers of fresh-keeping boxes is more uniform when stacking, and they can bite into each other and limit each other after stacking, which can effectively improve the stability during stacking.

[0032] like Figures 1 to 3 As shown, in this embodiment, gripping parts 131 are provided on two opposite side walls of the contraction part 13, and the staff can lift the fresh-keeping box for transportation or stacking by the gripping parts 131. The gripping parts 131 in this embodiment are arranged as grooves, which are convenient for the user's hand to be inserted for gripping.

[0033] like Figures 1 to 3 As shown, the box body 1 of this embodiment includes a bottom plate 14 and side plates 15 connected to each side of the bottom plate 14 and connected to each other, wherein the bottom plate 14 and a plurality of side plates 15 connected to each other together enclose a receiving cavity, and are connected to form a box opening 16 on a side of the box body 1 away from the bottom plate 14, and fresh products can be loaded into the receiving cavity of the box body 1 from the box opening 16, and the receiving cavity is sealed by closing the box cover 2 at the box opening 16, so as to ensure the fresh transportation of fresh products. In this embodiment, the side plates 15 and the bottom plate 14 of the box body 1 can be set as a combination plate with a heat preservation plate sandwiched between two plastic plates, for example, the heat preservation plate can be set as a foam plate or a cotton plate of a heat preservation material, so that the fresh-keeping box as a whole has a good heat preservation effect.

[0034] like Figures 1 to 3As shown, the snap-in edge 11 of this embodiment is arranged around the circumference of the box opening 16, so that after the box cover 2 is covered on the box opening 16, it can abut against the snap-in edge 11 to form an edge snap-in in the snap-in space formed by the snap-in step 12 and the side wall of the contraction portion 13, so as to achieve stable stacking of the heat preservation box; at the same time, after the box cover 2 of this embodiment is covered, it can also be snap-in with the snap-in edge 11, so as to achieve stable covering of the box cover 2. Specifically, at least one group of opposite side walls of the snap-in edge 11 of this embodiment is provided with a connecting groove 111, and a locking assembly 6 is provided in the connecting groove 111, which can lock the box cover 2 covered on the box body 1, so as to ensure the sealing and heat preservation effect of the fresh-keeping box of this embodiment. Among them, the locking assembly 6 of this embodiment includes a locking piece and a snap-fit ​​seat, the snap-fit ​​seat is arranged in the connecting groove 111, and the locking piece is arranged at a position on the side of the box cover 2 close to the box body 1 and corresponding to the connecting groove 111, so that when the box cover 2 is closed on the box body 1, the locking piece can be snapped into the snap-fit ​​seat, thereby realizing the buckling and fixing of the box cover 2 and improving the sealing degree of the closing between the box body 1 and the box cover 2.

[0035] like Figure 1 to Figure 2 As shown, in order to achieve a sealed and stable closing of the box cover 2, a protrusion 22 is provided at the bottom of the box cover 2 in this embodiment. When the box cover 2 is closed, the protrusion 22 can be inserted into the box body 1, thereby improving the stability of the box cover 2 after it is closed on the box body 1; at the same time, a sealing groove 23 is provided at the edge of the protrusion 22 of this embodiment, and a sealing edge 161 is provided at the top of the box opening 16. When the box cover 2 is closed, the sealing edge 161 can be inserted into the sealing groove 23, thereby improving the sealing effect after the box cover 2 is closed; and, in this embodiment, a sealing strip 3 made of silicone material is also provided in the sealing groove 23. After the sealing edge 161 is inserted into the sealing groove 23, it abuts against the sealing strip 3, thereby further improving the sealing effect of this embodiment.

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, the box body 1 of this embodiment is a cone structure with a gradually decreasing outer diameter from top to bottom, so that when the fresh-keeping box is transported empty, each box body 1 can remove the box cover 2 and plug it into each other for stacking, which can not only improve the stacking stability of the box body 1 during empty transportation, but also effectively reduce the space occupied, which is convenient for reducing transportation costs. In order to ensure that the box cover 2 can be stably stacked and transported when the fresh-keeping box is transported empty, this embodiment is provided with a bite groove 21 on the top surface of the box cover 2, wherein the bite groove 21 corresponds to the position of the protrusion 22 at the bottom of the box cover 2, so that when each box cover 2 is stacked and transported, the protrusion 22 at the bottom of the box cover 2 located at the top can be embedded in the bite groove 21 at the top of the box cover 2 located at the bottom, thereby achieving stable stacking of the box cover 2, and then achieving stable transportation of this embodiment.

[0037] like Figure 5As shown, mounting grooves 4 are provided on the end faces opposite to the bottom plate 14 of the box cover 2 of this embodiment, and a storage box 5 is detachably installed in the mounting groove 4, wherein the storage box 5 of this embodiment is used to store ice bags, and the storage box 5 is provided on the end face of the box cover 2, or the end face of the bottom plate 14, or the end faces of the box cover 2 and the bottom plate 14 are both provided with the storage box 5, and the storage box 5 can be connected and disassembled with the box cover 2 or the bottom plate 14, for example, the storage box 5 can be connected to the shell cover by a snap buckle, so that the connection and disassembly of the storage box 5 are relatively convenient, and the ice bag can be placed in a freezing device for refrigeration before the fresh-keeping box is used, and the ice bag can be placed in the storage box 5 when the fresh-keeping box needs to be loaded with products, so that after the box cover 2 is covered on the box body 1, a lower temperature can be provided for the box body 1, thereby ensuring the freshness of fresh fruits and vegetables.

[0038] To summarize, the working principle of the present embodiment is as follows: the present embodiment sets a box body 1 with a convex polygonal cross-section that is centrally symmetrical, and makes the cross-sectional area of ​​the box body 1 gradually decrease from the top of the box body 1 to the bottom of the box body 1 to form an inclined side wall, so that when the fresh-keeping boxes are stacked one front and one back for transportation, the side walls of adjacent fresh-keeping boxes can abut against each other, so that after the fresh-keeping boxes are stacked, the adjacent fresh-keeping boxes can limit each other, thereby improving the stability of the fresh-keeping boxes after stacking, facilitating stable transportation, and reducing transportation costs; and, after the fresh-keeping boxes are stacked front and back, the side walls of the fresh-keeping boxes that are in contact with each other can fill each other, making full use of the space and improving transportation efficiency. At the same time, this embodiment provides a protruding snap-in edge 11 on the top of the box body 1 and a circumferentially contracted snap-in step 12 at the bottom of the box body 1, so that when the fresh-keeping boxes are stacked and transported, the snap-in edges 11 of the boxes 1 stacked one front and one back can be snap-fitted onto the adjacent snap-in steps 12, so that after multiple fresh-keeping boxes are stacked, they can bite into each other under the action of the snap-in edges 11 and the snap-in steps 12, further improving the stability of the stacked fresh-keeping boxes and achieving stable transportation.
