The boxes are placed from top to bottom within the box. A second handle is mounted on the cold chain box and rotatably connected to it. An auxiliary component is also mounted on the cold chain box and connected to the handle. This auxiliary component contacts the boxes. The cold chain storage box, through its cooperation with the auxiliary component, supports and secures the boxes when multiple boxes are placed layer by layer inside the box, making the process convenient and quick. Furthermore, by rotating the handle, the auxiliary component lifts the boxes, facilitating easy handling and collection of fruits and vegetables.

[0004] However, the patent still has the following problems in actual use: For some goods that do not require special ventilation treatment, stacking can be used to ensure the stability and safety of the goods during transportation. The good sealing performance of the cold chain storage box can maintain the stability of the internal temperature of the box and prevent external air, moisture, dust and other impurities from entering the box and affecting the quality of the goods. This device is not convenient for stacking and sealing cold chain storage boxes, which reduces the effectiveness of use.

[0005] Therefore, a cold chain storage box that is easy to stack and store is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a cold chain storage box that is easy to stack and store, in order to solve the problem that existing cold chain storage boxes are not easy to stack stably and require auxiliary sealing, thus reducing their effectiveness.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a limiting component, when two boxes are stacked, the insert plate passes through the sealing frame and inserts into the slot, driving the moving plate to descend until the upper box and the lower box are in contact. At this point, the moving plate descends to its lowest position, and the bending rod drives the sealing frame to slide down to its lowest point. The sealing frame presses against the connection between the box and the cover, maintaining the seal at the connection and ensuring the stability of the stacked two boxes. The specific details are as follows:

[0019] 1. By setting a limiting component, the operator stacks two boxes one on top of the other. At this time, the insert plate of the upper box descends, allowing the insert plate to pass through the sealing frame and insert into the slot. The insert plate will also press the moving plate down. The moving plate slides inside the adjustment groove. The moving plate drives the bending rod and the lower plate to press down. The moving plate compresses the spring, and the bending rod and the lower plate will drive the sealing frame down until the upper box and the lower box are in contact. The moving plate descends to the lowest position, and the bending rod drives the sealing frame to slide down to the lowest point. The sealing frame is pressed tightly at the connection position between the box and the cover, maintaining the sealing at the connection position and ensuring the stability of the stacked two boxes. The fixation is achieved by the self-weight of the upper box, which also facilitates the subsequent disassembly of the two boxes. This solves the problem that existing cold chain storage boxes are not easy to stack stably and do not have auxiliary sealing treatment, which reduces the effectiveness of use.

[0020] 2. By setting up a box body, cover, partition, screw, and rotating block, the box body and cover are installed by hinges, which is convenient for opening and closing. The partition is adjustable in position. Since the bottom surface of the partition is in contact with the box body, the operator can rotate the rotating block, which drives the screw to rotate. The rotation of the screw adjusts the position of the partition, thus making it suitable for placing items of different sizes and improving the flexibility of use. Attached Figure Description

[0029] Please see Figure 1 - Figure 6 The present invention provides a technical solution: a cold chain storage box that is convenient for stacking and storage, including a box body 1 and a cover 2 that is hinged to the top of the box body 1. The box body 1 and the cover 2 are hinged together by a hinge to facilitate opening and closing. A limit component 3 is provided on the outside of the box body 1, and a partition 4 is slidably installed inside the box body 1.

[0030] The limiting component 3 includes a fixing plate 31 fixedly connected to the lower part of the outer side of the housing 1, an insert plate 32 fixedly connected to the bottom of the fixing plate 31, a receiving plate 33 fixedly connected to the upper part of the outer side of the housing 1, a slot 34 opened on the top of the receiving plate 33, and an adjustment groove 35 opened in the middle of the inside of the receiving plate 33.

[0031] The receiving plate 33 has a lower groove 37 at its bottom, and a spring 38 is installed inside the lower groove 37. A movable plate 36 is slidably connected inside the adjusting groove 35. The bottom of the movable plate 36 is connected to the spring 38, and both ends of the movable plate 36 are fixedly connected to bent rods 39.

[0032] The insert plate 32 is slidably connected to the slot 34, the slot 34 is connected to the adjustment groove 35, the adjustment groove 35 is connected to the lower groove 37, the top of the spring 38 is fixedly connected to the moving plate 36, there are at least two springs 38, and the bottom of the spring 38 is fixed to the inner bottom surface of the lower groove 37.

[0033] A sealing frame 310 is sleeved on the outside of the bent rod 39. The sealing frame 310 fits into the housing 1. The top of the bent rod 39 fits into the top of the sealing frame 310. A lower plate 311 is fixedly connected to the lower part of the outside of the bent rod 39. The top surface of the lower plate 311 fits into the bottom surface of the sealing frame 310.

[0034] The sealing frame 310 is U-shaped, the fixing plates 31 are symmetrically arranged on both sides of the outer side of the box 1, and the receiving plate 33 is located below the fixing plate 31.

[0035] The operator stacks the two boxes 1 one on top of the other. At this time, the insert plate 32 of the upper box 1 descends, so that the insert plate 32 passes through the sealing frame 310 and inserts into the slot 34. The insert plate 32 will press the moving plate 36 down. The moving plate 36 slides inside the adjustment groove 35. The moving plate 36 drives the bending rod 39 and the lower plate 311 to press down. The moving plate 36 compresses the spring 38, and the bending rod 39 and the lower plate 311 will drive the sealing frame 310 down.

[0036] When the upper box 1 and the lower box 1 are in contact, the moving plate 36 descends to its lowest position, and the bending rod 39 drives the sealing frame 310 to slide down to its lowest point. The sealing frame 310 is pressed against the connection position of the box 1 and the cover 2, maintaining the sealing of the connection position and ensuring the stability of the stacking of the two boxes 1. The fixing is achieved by the weight of the upper box 1, which also facilitates the subsequent disassembly of the two boxes 1.

A rotating block 6 is fixedly connected to the end of the screw 5 away from the inner wall of the housing 1.

[0038] The partition 4 is adjustable. Since the bottom surface of the partition 4 is in contact with the box body 1, the operator can rotate the rotating block 6, which drives the screw 5 to rotate. The rotation of the screw 5 adjusts the position of the partition 4, making it suitable for placing items of different sizes and improving the flexibility of use.

[0039] One side of the front, one side of the back and one side of the bottom of the partition 4 are respectively attached to the inner wall of the box 1. There are no less than two partitions 4, and the number of screws 5 is the same as that of partitions 4.

[0040] Working principle:

[0041] Before using this type of conveniently stackable cold chain storage box, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the operator rotates the rotating block 6, which drives the screw 5 to rotate. The rotation of the screw 5 adjusts the position of the partition 4, making it suitable for placing items of different sizes. By stacking the two boxes 1 one on top of the other, the insert plate 32 of the upper box 1 descends, allowing it to pass through the sealing frame 310 and insert into the slot 34. The insert plate 32 also presses the moving plate 36 down, causing it to slide inside the adjusting groove 35. The moving plate 36 then drives the bending rod 39 and the lower plate 311 to press down, thus moving the partition plate 4. The plate 36 compresses the spring 38, and the bending rod 39 and the lower plate 311 will drive the sealing frame 310 to descend until the upper box 1 and the lower box 1 are in contact. At this point, the moving plate 36 descends to the lowest position, and the bending rod 39 drives the sealing frame 310 to slide down to the lowest point. The sealing frame 310 is pressed against the connection position of the box 1 and the cover 2 to maintain the sealing of the connection position and ensure the stability of the stacking of the two boxes 1. The fixing is achieved by the weight of the upper box 1, which also facilitates the subsequent disassembly of the two boxes 1.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
