[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-4 As shown, this utility model is a turnover device for cold chain transportation of food, comprising:

[0032] A turnover box 100, with a box cover 200 fixedly connected to the top of the turnover box 100;

[0033] The clamping mechanism includes a pusher post 310, a connecting plate 320, an inclined plate 330, a clamping plate 340, and a first spring 350.

[0034] The push-button post 310 is slidably connected to the middle of the inner cavity of the box cover 200. Four connecting plates 320 are respectively fixedly connected to the side wall of the push-button post 310. Four inclined plates 330 are respectively slidably connected to the bottom of the inner cavity of the box cover 200. The ends of the connecting plates 320 are slidably connected to the inclined surfaces of the inclined plates 330. Four clamping plates 340 are respectively fixedly connected to the four inclined plates 330 and slide on the top surface of the box cover 200. The two ends of the first spring 350 are respectively fixedly connected to the bottom of the push-button post 310 and the bottom of the inner cavity of the box cover 200. The turnover box 100 is placed on the box cover 200 on top of the lower turnover box 100. The upper turnover box 100 slides down the pressing column 310 due to gravity. The pressing column 310 drives the connecting plate 320 to move down, so that the end of the connecting plate 320 slides on the inclined plate 330, thereby driving the inclined plate 330 to slide towards the center of the box cover 200. The inclined plate 330 drives the clamping plate 340 to slide towards the center of the box cover 200, clamping the bottom of the upper turnover box 100, thereby connecting all the stacked turnover boxes 100 together.

[0035] The surface of the box cover 200 is provided with long grooves 210 and short grooves 220. There are multiple long grooves 210 and short grooves 220. The bottom of the clamping plate 340 is fixedly connected to the bottom post 341 and the guide post 342. The bottom post 341 is fixedly connected to the top of the inclined plate 330 and slides in the long groove 210. The guide post 342 slides in the short groove 220. The sliding of the inclined plate 330 drives the bottom post 341 to slide in the long groove 210. The long groove 210 drives the clamping plate 340 to slide, so that the guide post 342 at the bottom of the clamping plate 340 slides in the short groove 220, ensuring the stability of the sliding of the clamping plate 340.

[0036] A protruding post 311 is fixedly connected to the side wall of the push post 310. The protruding post 311 is slidably connected to the inner cavity of the cover 200. The protruding post 311 restricts the push post 310 to slide up and down and cannot rotate.

[0037] The bottom of the inner cavity of the box cover 200 is fixedly connected to the guide rail 230. The bottom of the inclined panel 330 slides within the guide rail 230. The guide rail 230 guides the sliding direction of the inclined panel 330, so that it can only slide within the guide rail 230.

[0038] The inclined plate 330 has an inclined groove 331 on its inclined surface, and the end of the connecting plate 320 is fixedly provided with an inclined column 321. The inclined column 321 is slidably connected in the inclined groove 331. When the connecting plate 320 descends, it drives the inclined column 321 at the end to slide in the inclined groove 331 on the inclined surface of the inclined plate 330, thereby allowing the inclined plate 330 to slide in the guide rail 230.

[0039] Working principle: The upper turnover box 100 is placed on the box cover 200 on top of the lower turnover box 100. Due to gravity, the upper turnover box 100 slides downward on the pressing column 310. The pressing column 310 drives the connecting plate 320 to move downward. The downward movement of the connecting plate 320 causes the inclined column 321 at the end to slide in the inclined groove 331 on the inclined surface of the inclined panel 330, thereby causing the inclined panel 330 to slide in the guide rail 230. The sliding of the inclined panel 330 causes the bottom column 341 to slide in the long groove 230. The long groove 210 slides within the short groove 220, causing the clamping plate 340 to slide. This allows the guide post 342 at the bottom of the clamping plate 340 to slide within the short groove 220. The clamping plate 340 slides towards the center of the box cover 200, clamping the bottom of the upper turnover box 100 and connecting all the stacked turnover boxes 100 together. This increases the overall integrity of the stacked turnover boxes 100, thereby preventing the turnover boxes 100 from tipping over due to shaking during transportation, reducing the possibility of food damage inside the turnover boxes 100, and minimizing losses.

[0040] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0041] A slot 410 is provided on one side of the box cover 200, and a protruding tube 420 is fixedly connected to the other side of the box cover 200. A blocking component 430 is provided inside the protruding tube 420. The protruding tube 420 on one side of the box cover 200 is inserted into the slot 410 on the other side of the adjacent box cover 200. When the turnover boxes 100 are arranged horizontally, the protruding tube 420 on the side wall of one box cover 200 is aligned with the slot 410 on the other side of the adjacent box cover 200 and inserted. The blocking component 430 blocks the slot 410 and the protruding tube 420, so that the turnover boxes 100 are arranged together, further improving the overall integrity of the turnover boxes 100.

[0042] The blocking assembly 430 includes a square plate 431, a flap 432, a telescopic column 433, and a second spring 434;

[0043] The square plate 431 is slidably connected inside the convex tube 420. The telescopic column 433 and the second spring 434 are respectively fixedly connected to the bottom of the convex tube 420 and the bottom of the square plate 431. The flip plate 432 is rotatably connected to the top surface of the square plate 431. The flip plate 432 is initially vertical. After the convex tube 420 is inserted into the slot 410, the flip plate 432 is pulled to drive the square plate 431 to slide upward inside the convex tube 420, so that the telescopic column 433 and the second spring 434 are stretched. When the flip plate 432 is completely pulled out of the convex tube 420, the flip plate 432 is flipped to a horizontal state and released, so that the second spring 434 rebounds and drives the square plate 431 to descend. The square plate 431 drives the flip plate 432 to descend and block the slot 410 inside the convex tube 420, so that the box cover 200 is arranged and combined, thereby arranging and combining the turnover box 100.

[0044] The top surface of the second spring 434 is fixedly connected to a vertical plate 435. There are two vertical plates 435. The two ends of the flip plate 432 are fixedly connected to rotating columns 436. The rotating columns 436 are rotatably connected to the side wall of the vertical plate 435. Flipping the flip plate 432 causes the rotating columns 436 to rotate on the vertical plate 435.

[0045] Working principle: When the turnover boxes 100 are arranged horizontally, the protruding tube 420 on the side wall of one box cover 200 is aligned with the slot 410 on the other side of the adjacent box cover 200 and inserted. After the protruding tube 420 is inserted into the slot 410, the flip plate 432 is pulled and the square plate 431 is driven to slide upward in the protruding tube 420 through the upright plate 435, so that the telescopic column 433 and the second spring 434 are stretched. When the flip plate 432 is completely pulled out of the protruding tube 420, the flip plate 432 is flipped so that the rotating column 436 rotates on the upright plate 435, so that the flip plate 432 is flipped to a horizontal state and then released, so that the second spring 434 rebounds and drives the square plate 431 to descend. The square plate 431 drives the flip plate 432 to descend and block the slot 410 in the protruding tube 420, so that the box covers 200 are arranged horizontally and thus the turnover boxes 100 are arranged and combined, further improving the overall integrity of the turnover boxes 100.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
