[0003] A logistics turnover box according to Chinese patent CN207810121U includes a base plate, side plates and cover plate that cooperate with each other. The base plate, side plates and cover plate are respectively provided with a number of symmetrical telescopic rollers. This utility model is easy to handle, has multiple functions and is suitable for transporting items of different sizes.

[0004] Most common turnover boxes on the market are stacked by simply fitting the top and bottom of the box together. However, they lack effective limiting and fixing structures during the stacking process. They are prone to shifting or slipping due to external collisions, transportation bumps and other factors, which may not only damage the goods but also pose safety hazards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a turnover box with a limiting structure, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a turnover box with a limiting structure, comprising a turnover box, with frame plates fixedly connected to the upper and lower ends of the turnover box, connecting blocks fixedly connected to the four corners of the frame plates, limiting holes opened on the connecting blocks, first bolts threaded into the limiting holes, and nuts with connecting shafts threaded onto the first bolts, a groove opened at the bottom end of the frame plates, a box cover detachably connected to the inner wall of the turnover box, limiting plates fixedly connected to the four corners of the inner wall of the turnover box, corresponding second screw holes opened on the limiting plates and the box cover, screws threaded into the second screw holes, an inner groove opened at the top of the box cover, a wrench rotatably connected to the inner wall of the inner groove, and handles symmetrically rotatably connected to the side ends of the turnover box.

[0007] As a further technical solution of this utility model, the two ends of the frame plate located above the turnover box are respectively fixedly connected with slots and rotatably connected with blocks, and the slots and blocks on the two adjacent turnover boxes engage with each other. A card plate is symmetrically fixedly connected to one end of the frame plate, and the block is rotatably connected to the inner wall of the card plate.

[0008] As a further technical solution of this utility model, both the slot and the block are provided with corresponding first screw holes, and the first screw holes are internally threaded with second bolts.

[0009] As a further technical solution of this utility model, the groove depth is greater than the height of the screw protruding from the surface of the turnover box.

[0010] As a further technical solution of this utility model, clamping grooves are fixedly connected to the four corners of the bottom of the turnover box, and universal wheels are detachably connected in the clamping grooves.

[0011] As a further technical solution of this utility model, a connecting plate is fixedly connected to the top of the universal wheel, and the connecting plate engages with the clamping groove.

[0012] As a further technical solution of this utility model, the connecting block and the side end of the clamping groove are provided with corresponding limiting ports, and the limiting ports are inserted into the limiting ports.

[0013] This utility model provides a turnover box with a limiting structure, which has the following advantages compared with the prior art:

[0014] This design features a turnover box with a limiting structure. By holding the handles on both sides, one turnover box is stacked on top of the one below. The lid of the turnover box is embedded within the box and contacts the limiting plate. The lid is then positioned by inserting screws into the corresponding second screw holes. A wrench is then turned to engage the inner groove. The bottom frame plate of the turnover box has a groove deeper than the protruding screw, thus not affecting the stacking of the turnover boxes. The connecting blocks on the upper and lower turnover boxes overlap and fit together. A first bolt can be inserted into the corresponding connecting block, and the nut can be tightened by holding the connecting shaft to secure the thread. This design achieves vertical stacking limitation. When horizontal stacking of turnover boxes is required, the first screw hole on the side of the turnover box can be engaged with the corresponding slot on the adjacent turnover box, and then fixed with the second bolt thread. If horizontal stacking is not required, the first screw hole can be rotated and folded to be perpendicular to the turnover box to avoid protrusion affecting the handling of workers. Subsequently, the positions of multiple turnover boxes after stacking can be moved and adjusted using casters. Through this limiting structure, multiple turnover boxes can be stacked and placed in a limited position to prevent them from shifting or slipping due to external collisions, transportation bumps, or other factors.

[0021] Please see Figures 1-4 This utility model provides a technical solution for a turnover box with a limiting structure: it includes a turnover box 1, with frame plates 19 fixedly connected to the upper and lower ends of the turnover box 1 on the outer ring of the turnover box 1. Connecting blocks 5 are fixedly connected to the four corners of the frame plates 19. Limiting holes 20 are opened on the connecting blocks 5. First bolts 6 are threadedly connected to the limiting holes 20. Nuts 7 with connecting shafts 18 are threadedly connected to the first bolts 6. A groove 14 is opened at the bottom end of the frame plates 19. A box cover 2 is detachably connected to the inner wall of the turnover box 1. Limiting plates 16 are fixedly connected to the four corners of the inner wall of the turnover box 1. Second screw holes 15 are opened on the limiting plates 16 and the box cover 2. Screws 8 are threadedly connected to the second screw holes 15. An inner groove 9 is opened at the top of the box cover 2. A wrench 3 is rotatably connected to the inner wall of the inner groove 9. Handles 17 are symmetrically rotatably connected to the side ends of the turnover box 1.

[0022] Please see Figures 2-3 The frame plate 19 located above the turnover box 1 has slots 12 fixedly connected to its two symmetrical ends and blocks 4 rotatably connected to them. The slots 12 and blocks 4 on two adjacent turnover boxes 1 engage with each other. A plate 10 is symmetrically fixedly connected to one end of the frame plate 19, and the blocks 4 are rotatably connected to the inner wall of the plate 10. Both the slots 12 and the blocks 4 have corresponding first screw holes 11, and second bolts 13 are threaded into the first screw holes 11. The depth of the groove 14 is greater than the height of the screw 8 protruding from the surface of the turnover box 1.

[0023] Please see Figure 3The four corners of the bottom of the turnover box 1 are fixedly connected with clamping grooves 22. The universal wheels 21 are detachably connected in the clamping grooves 22.

The connecting block 5 and the side of the clamping grooves 22 are respectively provided with corresponding limiting holes 23, and the limiting holes 23 are inserted into the limiting holes 23.

[0024] The working principle of this utility model is as follows: First, the universal wheel 21 is inserted into the groove 22 at the bottom of the lowest turnover box 1 through the connecting plate 25, so that the groove 22 coincides with the limiting hole 23 on the connecting plate 25. Then, the limiting block 24 is inserted into the limiting hole 23 to limit the universal wheel 21. At this time, the other turnover box 1 is stacked on the turnover box 1 below by holding the handles 17 on both sides. The box cover 2 inside the turnover box 1 is embedded in the turnover box 1 and contacts the limiting plate 16. Then, the box cover 2 is positioned by inserting the screw 8 into the corresponding second screw hole 15. Then, the wrench 3 is rotated and embedded in the inner groove 9. The frame plate 19 at the bottom of the turnover box 1 is provided with a groove 14, the depth of which is greater than the height of the screw 8 protrusion, so as not to affect the stacking of the turnover boxes 1. The connecting blocks 5 on the upper and lower turnover boxes 1 are weighted. To achieve proper alignment, the first bolt 6 can be inserted into the corresponding connecting block 5, and the connecting shaft 18 can be held and the nut 7 can be screwed on to secure it, thus completing the vertical stacking limit. When horizontal stacking of the turnover boxes 1 is required, the first screw hole 11 on the side of the turnover box 1 can be engaged with the corresponding slot 12 on the adjacent turnover box 1, and then secured by the second bolt 13. If horizontal stacking is not required, the first screw hole 11 can be rotated and folded to be perpendicular to the turnover box 1 to avoid protrusion affecting the handling of workers. Subsequently, the positions of the stacked turnover boxes 1 can be adjusted by using the casters 21. Through this limiting structure, the stacking of multiple turnover boxes 1 is limited, preventing the stacked turnover boxes 1 from shifting or slipping due to external collisions, transportation bumps, or other factors.
