For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] like Figures 1 to 7 As shown, a turnover box with adjustable volume includes a supporting bottom plate 1, supporting legs 2, pads 3, a side box assembly 25, and a limiting connecting plate 4.

[0032] A set of supporting legs 2 are respectively provided at the four corners of the supporting base plate 1 , and the supporting legs 2 are used for the entire turnover box. The side panel box assembly 25 is provided on the supporting base plate 1 .

[0033] The side panel box assembly 25 includes side panels 5 and vertical ribs 6. There are 4 groups of side panels 5 and vertical ribs 6. The 4 groups of side panels form a square structure. Two adjacent side panels 5 are connected by vertical ribs 6. The lower part of the vertical ribs 6 is provided with vertical rib grooves 9, and the upper part of the vertical ribs 6 is provided with protrusions. There are at least two groups of side panel box assemblies 25 and they are stacked up and down. The stacking of multiple side panel box assemblies 25 is completed by inserting the vertical rib protrusions 8 on the upper part of the vertical ribs 6 of the side panel box assembly 25 located at the bottom into the vertical rib grooves 9 on the lower part of the vertical ribs 6 of the side panel box assembly 25 located at the top. The volume of the turnover box can be adjusted by adjusting the stacking number of the side panel box assemblies 25.

[0034] In order to further improve the connection stability of the two adjacent upper and lower side panel box assemblies 25, the upper part of the limiting connecting plate 4 is screwed to the vertical rib 6 of the upper side panel box assembly 25, and the lower part of the limiting connecting plate 4 is screwed to the vertical rib 6 of the lower side panel box assembly 25.

[0035] Through the above arrangement, the volume of the turnover box can be adjusted while ensuring the connection stability of the two adjacent side panel box assemblies 25.

[0036] The vertical ribs 6 can be constructed of a hollow square column. When the vertical ribs 6 are screwed to the limiting connecting plate 4, bolts and nuts 7 are typically used. This requires holes to be formed in the limiting connecting plate 4 and through holes to be formed on the side surfaces of the vertical ribs 6. The bolts are then passed through the holes in the limiting connecting plate 4 and the side surfaces of the vertical ribs 6. The nuts 7 are then screwed to the bolts inside the vertical ribs 6. However, the aforementioned method suffers from the difficulty of providing the nuts 7 inside the vertical ribs 6 for screwing to the bolts due to the limited size of the vertical ribs 6.

[0037] As a supplement to the technical solution of the present invention, a nut 7 is also included. The vertical rib 6 is a square columnar structure, and grooves for fixing the nut 7 are provided on its adjacent two side surfaces. The nut 7 is fixed in the groove on the side surface of the vertical rib 6. Preferably, the nut 7 is fixed in the groove on the side surface of the vertical rib 6 by welding.

[0038] The position-limiting connecting plate 4 is an L-shaped angled profile structure comprising a third side plate and a fourth side plate. The third and fourth side plates are arranged perpendicularly relative to each other, allowing the position-limiting connecting plate 4 to fit closely with the side surfaces of the vertical ribs 6, thereby increasing the contact area therebetween. Both the third and fourth side plates are provided with strip holes for bolts to pass through. The bolts pass through the strip holes in the third or fourth side plates and are then screwed onto nuts 7 located on the side surfaces of the vertical ribs 6. The design of the strip holes reduces machining precision requirements and facilitates installation.

[0039] As a supplement to the technical solution of this utility model, two sets of parallel plug-in plates 10 are provided on the adjacent side surfaces of the vertical rib 6, where the nuts 7 are not provided. The ends of the side panels 5 are inserted between the two sets of plug-in plates 10. By connecting the side panels 5 and the vertical ribs 6 through plug-in connection, a removable design is achieved, which makes assembly and disassembly flexible and convenient, reduces maintenance costs, and can be removed when not in use to save space. When connecting the side panels 5 to the vertical ribs 6, the ends of the side panels 5 are inserted between the two parallel plug-in plates 10.

[0040] The plug board 10 and the vertical rib 6 can be connected by welding or integrally formed. Figure 3 As shown, the vertical ribs 6 and the plug-in plate 10 of the present invention are aluminum profiles, which are extruded into one piece through an aluminum alloy extrusion process.

[0041] As a supplement to the technical solution of the present utility model, the support leg 2 includes a bearing portion 11 and a connecting portion 12 .

[0042] The load-bearing portion 11 is a square column structure, and the lower end of the connecting portion 12 is connected to the load-bearing portion 11. The connecting portion 12 includes a first side plate 13 and a second side plate 14. The first side plate 13 and the second side plate 14 are arranged perpendicular to each other to form an L-shaped beam structure.

[0043] The support base plate 1 is located at the upper end of the load-bearing portion 11 of the support leg 2. The lower end of the vertical rib 6 of the side panel box assembly 25 located below is located on the support base plate 1, and the two adjacent outer surfaces of the vertical rib 6 respectively abut against the first side plate 13 and the second side plate 14 of the connecting portion 12 of the support leg 2. The two adjacent side surfaces of the vertical rib 6 are connected to the first side plate 13 and the second side plate 14 of the connecting portion 12 by screwing. Specifically, the first side plate and the second side plate are each provided with a strip hole, and bolts are used to pass through the strip holes and screw into the nuts located on the side surfaces of the vertical rib 6.

[0044] As a preferred technical solution of the present invention, a pad foot 3 is provided at the lower end of the support leg 2 , and a pad foot groove 15 is provided on the lower bottom surface of the pad foot 3 .

[0045] When multiple groups of turnover boxes need to be stacked, the feet 3 of the turnover box on top can be placed on the vertical ribs 6 of the turnover box on the bottom, so that the vertical ribs 6 can be inserted into the grooves of the feet 3. The "bowl-shaped" structure of the feet 3 can play a role in positioning and limiting the stacking process, reducing the difficulty of the work and reducing accidents such as the turnover boxes slipping during transportation.

[0046] As a preferred technical solution of the present invention, the support base plate 1 includes a panel 16 and a support base plate frame, and the support base plate frame includes long side beams 17, short side beams 18, middle-long beams 19, and middle-short beams 20.

[0047] Two sets of long side beams 17 and short side beams 18 are provided, forming a rectangular frame structure. A medium-long beam 19 connects between the two sets of short side beams 18, and a medium-short beam 20 connects between the medium-long beams 19 and the long side beams 17. The beams can be connected by welding. The panel 16 is mounted on the supporting base frame, and the panel 16 and the supporting base frame can be connected by welding.

[0048] As a supplement to the above technical solution, the side panels include side panels 21 and a side wall frame. The side wall frame includes short side frames 22, long side frames 23, and reinforcement tubes 24. The short side frames 22 and long side frames 23 are each provided in two sets, forming a square frame structure. Reinforcement tubes 24 are connected between the two sets of long side frames 23. The number of reinforcement tubes 24 can be selected based on the length of the long side frames 23. The side panels 21 are mounted on the side wall frame and can be connected to the side wall frame by welding.

[0049] As a supplement to the technical solution of the present invention, the support base 1, legs 2, feet 3, side panel box assembly 25, and limit connecting plate 4 are all made of aluminum alloy. Aluminum alloy has excellent corrosion resistance and can cope with various harsh environment usage scenarios.

[0050] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
