Description

Technical Field

[0001] The present invention relates to the field of logistics equipment, and in particular to a foldable logistics turnover box. Background Art

[0002] In the modern logistics industry, logistics turnover boxes are used frequently and extensively as an important tool for cargo storage and transportation. Foldable logistics turnover boxes are favored by many logistics companies because they can reduce space occupied when not in use and are easy to store, carry and transport. However, when the turnover boxes are unfolded and used, they are usually only fixed and connected by conventional methods such as screws or buckles. When the turnover box contains large and heavy goods, or is subject to bumps, vibrations and large inertia during transportation, the goods inside the box will impact the foldable box boards outward due to inertia. At this time, conventional connection methods often cannot withstand large impact forces, resulting in deformation, loosening and even damage at the box board connections; This situation will not only affect the normal use of turnover boxes and reduce their service life, but may also cause the goods to be scattered or damaged during transportation, causing economic losses to logistics companies. Moreover, frequent replacement of damaged turnover boxes also increases logistics operating costs. In addition, the reinforcement measures of traditional turnover boxes are relatively limited and cannot effectively disperse and buffer the impact of goods on the box board, making it difficult to meet the needs of modern logistics for efficient and safe transportation. Summary of the invention

[0003] The main purpose of the present invention is to propose a foldable logistics turnover box, which aims to solve the problem that the existing foldable logistics turnover boxes rely on conventional methods such as screws or buckles to fix the box plates. When storing heavier and larger goods or being subjected to bumps, vibrations and inertia during transportation, the conventional connection methods are difficult to withstand the impact force, causing the box plate connections to deform, loosen or even be damaged, affecting the use and life of the turnover box, causing damage to the goods, and increasing logistics costs. In addition, traditional reinforcement measures are limited and cannot meet the needs of modern logistics.

[0004] In order to solve the above problems, the present invention proposes a foldable logistics turnover box, including a box base and narrow foldable box boards arranged on the top of the left and right ends of the box base, a long foldable box board A is arranged on the top of the front end of the box base, and a long foldable box board B is arranged on the top of the rear end of the box base, the vertical lengths of the long foldable box board A, the long foldable box board B and the two narrow foldable box boards are equal, the thicknesses of the long foldable box board A, the long foldable box board B and the two narrow foldable box boards are equal, the two ends of the two narrow foldable box boards are fixedly connected to the long foldable box board A and the long foldable box board B by a plurality of hand-tightened screws, the sum of the vertical lengths of the two narrow foldable box boards is less than the length of the box base, and the outer walls of the four corners of the long foldable box board A, the long foldable box board B and the two narrow foldable box boards are connected with anti-support reinforcement devices.

[0005] In one embodiment, the anti-support reinforcement device connected at the corner of the long foldable box board A and the narrow foldable box board on the right side includes a U-shaped metal connecting block A, a triangular metal reinforcement plate and a U-shaped metal connecting block B. When the long foldable box board A is in an upward vertical state, a U-shaped metal connecting block A is fixed on the right side of the center of the front end outer wall. When the narrow foldable box board is in an upward vertical state, a U-shaped metal connecting block B is fixed on the front side of the center of the right end outer wall. The installation heights of the U-shaped metal connecting block A and the U-shaped metal connecting block B are equal, and the U-shaped opening directions of the U-shaped metal connecting block A and the U-shaped metal connecting block B are both facing upward. The U-shaped interiors of the U-shaped metal connecting block A and the U-shaped metal connecting block B are inserted with triangular metal reinforcement plates.

[0006] In one embodiment, the anti-support reinforcement device also includes a metal anti-slip block A and a metal anti-slip block B, wherein the metal anti-slip block A is welded to the left end of the triangular metal reinforcement plate, and the metal anti-slip block A is blocked at the left end of the U-shaped metal connecting block A, and the metal anti-slip block B is welded to the right rear end of the triangular metal reinforcement plate, and the metal anti-slip block B is blocked at the rear end of the U-shaped metal connecting block B.

[0007] In one embodiment, the metal anti-slip block A, U-shaped metal connecting block A, triangular metal reinforcement plate, U-shaped metal connecting block B and metal anti-slip block B are all made of aluminum-magnesium alloy, and the metal anti-slip block A and the metal anti-slip block B are flush with the upper and lower outer walls of the triangular metal reinforcement plate.

[0008] In one embodiment, after the triangular metal reinforcement plate is inserted into the metal anti-detachment block A and the metal anti-detachment block BU type, the triangular metal reinforcement plate is flush with the top outer wall of the metal anti-detachment block A and the metal anti-detachment block B, and the triangular metal reinforcement plate and the metal anti-detachment block A and the metal anti-detachment block B are interference fit.

[0009] In one embodiment, when the long foldable box board A, the long foldable box board B and the two narrow foldable box boards are rotated to an upward vertical state, a sleeve-type box cover is sleeved on the outside of the top end of the long foldable box board A, the long foldable box board B and the two narrow foldable box boards, and the left and right ends of the sleeve-type box cover are fixedly connected to the two narrow foldable box boards by hand-tightened screws.

[0010] In one embodiment, short rotating connecting blocks are provided at the top of both left and right ends of the box base, short rotating connecting grooves are provided inside the bottom ends of the two narrow foldable box panels, and the short rotating connecting grooves are sleeved on the outside of the short rotating connecting blocks, and both ends of the short rotating connecting blocks are connected to the narrow foldable box panels through rotating shafts.

[0011] In one embodiment, a long rotating connecting block A is provided at the top front end of the box base, a long rotating connecting groove A is provided inside the bottom end of the long foldable box board A, and the long rotating connecting groove A is sleeved on the outside of the long rotating connecting block A, and both ends of the long rotating connecting block A are connected to the long foldable box board A through a rotating shaft.

The long rotating connecting groove B is sleeved on the outside of the long rotating connecting block B, and both ends of the long rotating connecting block B are connected to the long foldable box board B through a rotating shaft.

[0013] In one embodiment, the vertical depths of the long rotating connecting groove B, the long rotating connecting groove A and the two short rotating connecting grooves decrease successively, the two narrow foldable box panels can be rotated and fitted on the box base through a rotating shaft, the long foldable box panel A can be rotated backward through the rotating shaft to two horizontal narrow foldable box panels, and the long foldable box panel B can be rotated forward through the rotating shaft to the horizontal long foldable box panel A.

[0014] Beneficial effect: The technical solution of the present invention is to add a new type of anti-support reinforcement device at the four corners of the two long foldable box boards and the two narrow foldable box boards that are unfolded to an upward vertical state. When the two long foldable box boards and the two narrow foldable box boards are unfolded to an upward vertical state, the four need to be fixedly connected by screws or buckles. However, when the objects stored inside the turnover box are too large or there is a large degree of inertia during transportation, the objects inside the box will impact the foldable box boards outward due to inertia, and the new type of anti-support reinforcement device can greatly enhance the structural strength of the connection between the box boards. The triangular metal reinforcement plate is inserted into the U-shaped metal connecting block A and the U-shaped metal connecting block B, and cooperates with the metal anti-detachment block A and the metal anti-detachment block B to form a stable connection structure, which effectively disperses the impact force. Even if it is subjected to a large impact, it can prevent the box board connection from deformation or damage, thereby ensuring the stability of the overall structure of the turnover box, avoiding the impact of loose box boards on the storage and transportation safety of goods, and greatly improving the durability and reliability of the turnover box.

[0022] The present invention provides Figure 1-5A foldable logistics turnover box shown in the figure comprises a box base 1 and narrow foldable box boards 6 arranged at the top of the left and right ends of the box base 1, a long foldable box board A5 is arranged at the top of the front end of the box base 1, and a long foldable box board B11 is arranged at the top of the rear end of the box base 1. The vertical lengths of the long foldable box board A5, the long foldable box board B11 and the two narrow foldable box boards 6 are equal, and the thicknesses of the long foldable box board A5, the long foldable box board B11 and the two narrow foldable box boards 6 are equal. The two ends of the narrow foldable box board 6 are fixedly connected to the long foldable box board A5 and the long foldable box board B11 by multiple hand-tightened screws 9. The sum of the vertical lengths of the two narrow foldable box boards 6 is less than the length of the box base 1. When the long foldable box board A5, the long foldable box board B11 and the two narrow foldable box boards 6 are rotated to an upward vertical state, the top of the long foldable box board A5, the long foldable box board B11 and the two narrow foldable box boards 6 are sleeved with a sleeved box cover 10, and the sleeved box cover 10 is sleeved. The left and right ends of the box cover 10 are fixedly connected to the two narrow foldable box boards 6 by hand-tightened screws 9. When each box board is unfolded to an upward vertical state to form a complete turnover box, the stability of the structure needs to be ensured. The two ends of the two narrow foldable box boards 6 are fixedly connected to the long foldable box boards A5 and the long foldable box boards B11 by multiple hand-tightened screws 9. This connection method is convenient for operation during assembly and disassembly, and no additional tools are required. When the long foldable box boards A5, the long foldable box boards B11 and the two narrow foldable box boards 6 are all rotated to an upward vertical state, a sleeve-type box cover 10 is sleeved on the outside of their top ends, and the left and right ends of the sleeve-type box cover 10 are also fixedly connected to the two narrow foldable box boards 6 by hand-tightened screws 9. This multi-layer connection and fixing method allows the box boards to be tightly combined during use of the turnover box to form a stable overall structure, effectively preventing the box boards from loosening due to the weight of the goods or vibration during transportation, thereby ensuring the safe storage and transportation of goods.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, short rotating connecting blocks 8 are arranged on the top of both left and right ends of the box base 1, short rotating connecting grooves 7 are arranged inside the bottom ends of the two narrow foldable box panels 6, and the short rotating connecting grooves 7 are sleeved on the outside of the short rotating connecting blocks 8, and both ends of the short rotating connecting blocks 8 are connected to the narrow foldable box panels 6 through rotating shafts, a long rotating connecting block A2 is arranged on the top of the front end of the box base 1, a long rotating connecting groove A3 is arranged inside the bottom end of the long foldable box panel A5, and the long rotating connecting groove A3 is sleeved on the outside of the long rotating connecting block A2, and both ends of the long rotating connecting block A2 are connected to the long foldable box panel A5 through rotating shafts, a long rotating connecting block B13 is arranged on the top of the rear end of the box base 1, and the long foldable box panel A long rotating connection groove B12 is provided inside the bottom end of B11, and the long rotating connection groove B12 is sleeved on the outside of the long rotating connection block B13, and both ends of the long rotating connection block B13 are connected to the long foldable box board B11 through a rotating shaft. The vertical depths of the long rotating connection groove B12, the long rotating connection groove A3 and the two short rotating connection grooves 7 decrease in sequence. The two narrow foldable box boards 6 can be rotated to fit on the box base 1 through the rotating shaft, and the long foldable box board A5 can be rotated backwards to the two horizontal narrow foldable box boards 6 through the rotating shaft, and the long foldable box board B11 can be rotated forwards to the horizontal long foldable box board A5 through the rotating shaft. The turnover box is realized through a variety of rotating connection structures. In order to realize the foldable function of each box panel, rotating connecting blocks of different lengths and corresponding rotating connecting grooves are respectively arranged at the connecting parts between the box base 1 and each foldable box panel. For example, the short rotating connecting blocks 8 at the top of the left and right ends of the box base 1 cooperate with the short rotating connecting grooves 7 inside the bottom of the narrow foldable box panel 6. The two ends of the short rotating connecting blocks 8 are connected to the narrow foldable box panel 6 through a rotating shaft. This structure allows the narrow foldable box panel 6 to rotate around the rotating shaft. Similarly, the long foldable box panel A5 and the long rotating connecting block A2 at the top of the front end of the box base 1, as well as the long foldable box panel B11 and the long rotating connecting block B13 at the top of the rear end of the box base 1, also adopt a similar connection method. The depths of the long rotating connecting groove B12, the long rotating connecting groove A3 and the two short rotating connecting grooves 7 decrease successively. This depth difference design ensures the flexibility of rotation of each box board on the one hand, and on the other hand ensures that each box board can fit together in a predetermined manner during the folding process to achieve a compact folding effect. The two narrow foldable box boards 6 can be rotated and fitted on the box base 1 through the rotating shaft, and the long foldable box board A5 can be rotated backward through the rotating shaft to the two horizontal narrow foldable box boards 6, and the long foldable box board B11 can be rotated forward through the rotating shaft to the horizontal long foldable box board A5, so that the space occupied by the turnover box when not in use is greatly reduced, which is convenient for storage and transportation.

[0024] like Figure 1 and Figure 5As shown, the outer walls of the four corners of the long foldable box board A5, the long foldable box board B11 and the two narrow foldable box boards 6 are all connected with anti-support reinforcement devices 4. The anti-support reinforcement device 4 connected at the corner of the long foldable box board A5 and the narrow foldable box board 6 on the right side includes a U-shaped metal connecting block A15, a triangular metal reinforcement plate 16 and a U-shaped metal connecting block B17. When the long foldable box board A5 is in an upward vertical state, a U-shaped metal connecting block A15 is fixed on the right side of the center of the front end outer wall, and the narrow foldable box board 6 is in an upward vertical state, a U-shaped metal connecting block B17 is fixed at the front side of the center of the right end outer wall, the installation height of the U-shaped metal connecting block A15 and the U-shaped metal connecting block B17 are equal, the U-shaped opening directions of the U-shaped metal connecting block A15 and the U-shaped metal connecting block B17 are both facing upward, and a triangular metal reinforcing plate 16 is inserted into the U-shaped interior of the U-shaped metal connecting block A15 and the U-shaped metal connecting block B17. The plug-in cooperation of the metal reinforcement plate 16 can realize the reinforcement of the corners of the turnover box panels. When the long foldable box panel A5 and the narrow foldable box panel 6 on the right are in an upward vertical state, the U-shaped metal connecting block A15 is fixed to the right side of the center of the outer wall of the front end of the long foldable box panel A5, and the U-shaped metal connecting block B17 is fixed to the front side of the center of the outer wall of the right end of the narrow foldable box panel 6. The two are installed at the same height and the U-shaped opening is facing upward. This setting provides a stable installation foundation for the triangular metal reinforcement plate 16. The triangular metal reinforcement plate 16 is plugged into the U-shaped interior of the U-shaped metal connecting block A15 and the U-shaped metal connecting block B17 to form a stable triangular support structure. The triangular structure is stable and can effectively disperse the external force on the box panel. The impact force is transmitted to the U-shaped metal connecting block A15 and the U-shaped metal connecting block B17 through the triangular metal reinforcement plate 16, and then dispersed to the box panel by them, thereby enhancing the bearing capacity of the box panel corners and preventing the box panel from being deformed or damaged due to external force impact.

[0025] like Figure 1 and Figure 5As shown, the anti-support reinforcement device 4 also includes a metal anti-slip block A14 and a metal anti-slip block B18. The metal anti-slip block A14 is welded to the left end of the triangular metal reinforcement plate 16, and the metal anti-slip block A14 is blocked at the left end of the U-shaped metal connecting block A15. The metal anti-slip block B18 is welded to the right rear end of the triangular metal reinforcement plate 16, and the metal anti-slip block B18 is blocked at the rear end of the U-shaped metal connecting block B17. The arrangement of the metal anti-slip block A14 and the metal anti-slip block B18 further enhances the reliability of the structure. The metal anti-slip block A14 is welded to the left end of the triangular metal reinforcement plate 16 and is blocked at the At the left end of the U-shaped metal connecting block A15, the metal anti-detachment block B18 is welded to the right rear end of the triangular metal reinforcement plate 16 and is blocked at the rear end of the U-shaped metal connecting block B17. This design effectively prevents the triangular metal reinforcement plate 16 from escaping from the U-shaped metal connecting block A15 and the U-shaped metal connecting block B17 when subjected to external force. Even when the turnover box is subjected to severe vibration or large impact force, the metal anti-detachment block A14 and the metal anti-detachment block B18 can ensure that the triangular metal reinforcement plate 16 always remains in the correct position, continues to play a reinforcing role, and ensures the stability and effectiveness of the entire anti-support reinforcement device 4.

[0026] like Figure 1 and Figure 5 As shown, the metal anti-slip block A14, the U-shaped metal connecting block A15, the triangular metal reinforcing plate 16, the U-shaped metal connecting block B17 and the metal anti-slip block B18 are all made of aluminum-magnesium alloy. The metal anti-slip block A14 and the metal anti-slip block B18 are flush with the upper and lower outer walls of the triangular metal reinforcing plate 16 respectively. After the triangular metal reinforcing plate 16 is inserted into the U-shaped interior of the metal anti-slip block A14 and the metal anti-slip block B18, the triangular metal reinforcing plate 16 is flush with the top outer walls of the metal anti-slip block A14 and the metal anti-slip block B18. The triangular metal reinforcing plate 16 and the metal anti-slip block A14 and the metal anti-slip block B18 are all interference fit. The aluminum-magnesium alloy has the advantages of low density, high strength, corrosion resistance, etc. The low density can reduce the overall weight of the turnover box while ensuring the reinforcement effect. The low weight makes it easy to carry and transport, and its high strength can meet the needs of the anti-support reinforcement device 4 to withstand large external forces, ensuring that it can effectively function in various usage environments. The corrosion resistance can extend the service life of the anti-support reinforcement device 4 and reduce the risk of structural damage due to corrosion. In addition, the metal anti-slip block A14 and the metal anti-slip block B18 are flush with the upper and lower outer walls of the triangular metal reinforcement plate 16, respectively. After the triangular metal reinforcement plate 16 is inserted into the U-shaped interior of the metal anti-slip block A14 and the metal anti-slip block B18, it is flush with their top outer walls, and an interference fit is adopted between them. This design not only ensures the flatness of the appearance of the entire anti-support reinforcement device 4, but also enhances the tightness of the connection between the components through interference fit, further improving the overall stability and external force resistance of the device.

[0027] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
