[0002] Logistics turnover boxes play an important role in the field of logistics. They have the advantages of saving space, high convenience, and strong versatility. They can make the turnover of parts more convenient and stack them neatly. In order to transport and store turnover boxes, foldable turnover boxes are usually selected.

[0003] Currently, common turnover boxes are usually made of plastic, and in order to make the turnover boxes foldable, the four side panels and the bottom panel of the turnover box are separated from each other, and the side panels are detachably connected to each other, and the side panels are hinged to the bottom panel, so as to realize the folding and unfolding of the turnover box.

[0004] However, because the side panels and the bottom panel are independent of each other, the connection strength between the side panels and the bottom panel is usually low. In order to reduce the weight of the turnover box and make it lighter, the side panels and the bottom panel of the turnover box are usually weaker and have lower strength, especially the connection between the side panels and the hinge between the side panels and the bottom panel, which are more likely to break and cause damage to the turnover box.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-7 This application is described in further detail.

[0044] Reference Figure 1 This embodiment discloses a foldable turnover box, comprising a first side panel 1, a second side panel 2 and a bottom panel 3. The bottom panel 3 is rectangular, and there are two first side panels 1 and two second side panels 2. The two first side panels 1 are arranged oppositely at the two ends of the bottom panel 3 in the length direction, and the two second side panels 2 are arranged oppositely at the two ends of the bottom panel 3 in the width direction, thereby forming a rectangular turnover box.

[0045] In order to realize the mutual connection between the first side panel 1, the second side panel 2 and the bottom panel 3, the first frame 4 is provided on both lateral sides of the first side panel 1, the second frame 5 is provided on both lateral sides of the second side panel 2, and the third frame 6 is provided at the four corners of the bottom panel 3. Further, the first frame 4 extends from the upper side of the first side panel 1 to the lower side of the first side panel 1, and the bottom side of the first frame 4 is hinged to the third frame 6, and the second frame 5 is connected to the first frame 4.

[0046] Therefore, since the first frame 4 and the third frame 6 can rotate relative to each other, the first side panel 1 and the bottom panel 3 can rotate relative to each other. The second side panel 2 is connected to the first frame 4 through the second frame 5, thereby realizing the connection between the first side panel 1 and the second side panel 2, and realizing the disassembly and folding of the first side panel 1 and the second side panel 2.

[0047] As a preferred implementation of the embodiment of the present application, the bottoms of the first side panel 1 and the second side panel 2 are kept relatively fixed with the bottom panel 3, and the upper and lower parts of the first side panel 1 and the second side panel 2 are relatively bent, so that the first side panel 1 and the second side panel 2 are folded.

[0048] Reference Figure 2 and Figure 3 In the embodiment of the present application, in order to achieve relative fixation between the first frame 4 and the first side panel 1, the first frame 4 is composed of two first brackets 41 arranged opposite to each other and a first fixing column 42 arranged between the two first brackets 41, and the two ends of the first fixing column 42 are respectively connected to the two first brackets 41. The first side panel 1 is provided with a first fixing groove 11 that is plugged and matched with the first fixing column 42, thereby ensuring that the first frame 4 is firmly fixed to the first side panel 1. Furthermore, the first fixing column 42 is fixedly connected to one of the first brackets 41 and detachably connected to the other first bracket 41, so that the two first brackets 41 can be separated, thereby achieving the separation and disassembly of the first frame 4 and the first side panel 1.

[0049] Furthermore, in order to improve the stability of the connection between the first frame 4 and the first side panel 1 , the first frame 4 is further provided with a limiting block 7 , and the first side panel 1 is provided with a limiting groove that is engaged with the limiting block 7 .

[0050] Reference Figure 4 and Figure 5Similarly, in order to achieve the relative fixation between the second frame 5 and the second side panel 2, the second frame 5 is composed of two second brackets 51 arranged opposite to each other and a second fixing column 52 arranged between the two second brackets 51, and the two ends of the second fixing column 52 are respectively connected to the two second brackets 51. The second side panel 2 is provided with a second fixing groove 21 that is plugged and matched with the second fixing column 52, thereby ensuring that the second frame 5 is firmly fixed to the second side panel 2. Furthermore, the second fixing column 52 is fixedly connected to one of the second brackets 51 and detachably connected to the other second bracket 51, so that the two second brackets 51 can be separated, thereby achieving the separation and disassembly of the second frame 5 and the second side panel 2.

[0051] Furthermore, in order to improve the stability of the connection between the second frame 5 and the second side plate 2 , the second frame 5 is further provided with a limiting block 7 , and the second side plate 2 is provided with a limiting groove that is engaged with the limiting block 7 .

[0052] Reference Figure 6 The connection between the bottom plate 3 and the third frame 6 is achieved by opening a connection groove 62 on the side of the third frame 6 and plugging the edge of the bottom plate 3 into the connection groove 62.

[0053] Furthermore, in order to improve the stability of the connection between the bottom plate 3 and the third frame 6 , a limiting block 7 is also provided on the third frame 6 , and a limiting groove that is engaged with the limiting block 7 is also provided on the bottom plate 3 .

[0054] Since the bottom of the second side panel 2 is suspended, in order to improve the stability of the second side panel 2, the bottom of the second side panel 2 is arranged on one lateral side of the bottom panel 3 and abuts against the side edge of the bottom panel 3, and the second side panel 2 is located between the bottom panel 3 and the third frame 6. The third frame 6 cooperates with the bottom panel 3 to achieve a clamping effect on the second side panel 2 to ensure the stability of the second side panel 2. In addition, the third frame 6 is also provided with a mounting groove 61, and the second side panel 2 is arranged in the mounting groove 61, thereby effectively improving the integrity of the third frame 6 and the second side panel 2.

[0055] Reference Figure 7 In order to facilitate the disassembly of the first frame 4 and the second frame 5, and thus facilitate the folding of the first side panel 1 and the second side panel 2, a detachable component 8 is also provided between the first frame 4 and the second frame 5, that is, the first frame 4 and the second frame 5 are connected via the detachable component 8.

[0056] In the present application, the detachable component 8 includes a driving block 81 and an insertion rod 82. The driving block 81 is installed on the second frame 5. Specifically, an operating hole is provided on the second frame 5. The driving block 81 is slidably set in the operating hole. The insertion rod 82 is fixed to the driving block 81, and one end of the insertion rod 82 extends toward the first frame 4. A slot 54 is provided on the first frame 4. The driving block 81 can be operated to make the insertion rod 82 cooperate with the slot 54, thereby realizing the splitting or connection of the first frame 4 and the second frame 5.

[0057] Furthermore, the driving block 81 is also provided with an elastic reset member 83. In the embodiment of the present application, the elastic reset member 83 is specifically a spring sheet, which abuts against the inner wall of the operation hole to achieve automatic reset of the driving member and lock the insertion rod 82. This design makes the connection and removal of the insertion rod 82 more convenient, and the elastic reset member 83 can ensure the stability of the insertion rod 82 in the connected state.

[0058] In addition, the elastic return member 83 may also be an elastic structure such as a spring.

[0059] In order to improve the connection strength between the first frame 4 and the second frame 5, and thus improve the load-bearing performance of the turnover box, a load-bearing groove 43 is further provided on the first frame 4, and a load-bearing block 53 is provided on the second frame 5 to be plugged into the load-bearing groove 43. This design can further improve the structural stability of the turnover box when bearing load, can effectively disperse the pressure, and prevent structural damage caused by excessive local pressure.

[0060] Furthermore, a first cross bar 45 is connected to the top of the first side panel 1, and the first cross bar 45 is fixedly connected to the first frame 4; a second cross bar 55 is connected to the top of the second side panel 2, and the second cross bar 55 is fixedly connected to the second frame 5. The design of these cross bars can further increase the structural stability of the turnover box and prevent the first side panel 1 or the second side panel 2 from being deformed or damaged when stacked or bearing load.

[0061] The implementation principle of the embodiment of the present application is: the first frame 4, the second frame 5 and the third frame 6 are used to respectively enhance the strength of the first side panel 1, the second side panel 2 and the bottom panel 3, thereby effectively enhancing the structural strength of the turnover box. The first frame 4, the second frame 5 and the third frame 6 can be made of aluminum alloy or other materials with high strength and light weight. At the same time, the hinge of the first frame 4 and the third frame 6 and the detachable connection of the second frame 5 and the first frame 4 ensure the folding function of the turnover box. In addition, the first side panel 1, the second side panel 2 and the bottom panel 3 can be made of light materials, such as light plastic boards, wooden boards, corrugated cardboard, etc., so as to ensure the lightness of the turnover box.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
