Logistics turnover box capable of being stacked in staggered mode

Abstract

The utility model discloses a logistics turnover box capable of being stacked in a staggered mode. The logistics turnover box comprises a bottom plate, a long side plate A, a short side plate A, a long side plate B and a short side plate B, wherein a part of each of the four side plates protrudes outwards, so that a limiting groove is formed in the inner side face, a limiting protruding strip is correspondingly formed on the outer side face, and positioning grooves matched with the limiting protruding strip are further formed in the inner side faces of the four side plates respectively; the positioning grooves and the limiting grooves in the two oppositely-distributed side plates are distributed in a staggered mode. Therefore, after the logistics turnover box is filled with goods, staggered stacking can be formed through insertion matching of the positioning grooves and the limiting protruding strips, and after a plurality of logistics turnover boxes are stacked together, the stability is high, and sliding or collapse is not prone to occurring; when the logistics turnover box is an empty box, a plurality of empty boxes can be stacked together in a sleeved mode to be stored through insertion matching of the limiting grooves and the limiting protruding strips, and therefore the storage size can be reduced, the transportation space can be saved, and the transportation cost can be reduced.

Description

Technical Field

[0001] This utility model relates to the field of logistics turnover box technology, specifically to a logistics turnover box that can be stacked in a staggered manner. Background Technology

[0002] With the development of digital intelligence and shared transportation units in my country's logistics and transportation industry, the demand for logistics turnover boxes—the basic unit of logistics and transportation—is increasing day by day. Logistics turnover boxes are mainly used to place goods that need to be moved around, so as to facilitate the transfer of goods. They are not only suitable for large-scale production and use, but also for transportation, distribution, storage and processing in factory logistics.

[0003] In practical use, to maximize cargo storage, the internal and external dimensions of logistics turnover boxes need to be continuously expanded to increase the cargo capacity of a single box. However, this also results in a significant increase in space occupied during the placement and transportation of empty boxes. To address this, manufacturers have developed foldable logistics turnover boxes. These boxes can be assembled from multiple components to accommodate large-space transport of goods, and disassembled to allow for folding when empty, saving transport space and reducing costs. However, this type of logistics turnover box typically requires a large number of assembly components, leading to higher manufacturing costs and hindering its widespread adoption by small and medium-sized developers. Utility Model Content

[0004] This invention provides a staggered stackable logistics turnover box to overcome the aforementioned problems in the prior art. The staggered stackable logistics turnover box of this invention features limiting protrusions on the outer surfaces of its four side panels, and corresponding limiting grooves and positioning grooves on the inner surfaces that match the limiting protrusions. The positioning grooves and limiting grooves on two oppositely distributed side panels are staggered. Therefore, when the logistics turnover box is full of goods, it can be stacked in a staggered manner through the interlocking of the positioning grooves and limiting protrusions. Multiple logistics turnover boxes stacked together have high stability and are not prone to sliding or collapsing. When the logistics turnover box is empty, multiple empty boxes can be nested together for storage through the interlocking of the limiting grooves and limiting protrusions, thereby reducing storage volume, saving transportation space, and lowering transportation costs.

[0005] The technical solution of this application is as follows: a stackable logistics turnover box with staggered positioning, including a base plate, and A long side plate, A short side plate, B long side plate, and B short side plate connected end to end on the base plate; positioning grooves are respectively formed on the inner surfaces of the A long side plate, A short side plate, B long side plate, and B short side plate, and a portion of each of the A long side plate, A short side plate, B long side plate, and B short side plate protrudes outward, thereby forming a limiting groove on the inner surface and a corresponding limiting protrusion on the outer surface; the positioning grooves and limiting grooves on the A long side plate and B long side plate are staggered; the positioning grooves and limiting grooves on the A short side plate and B short side plate are staggered; the lower end of the limiting protrusion is adapted to the positioning groove.

[0006] When two logistics turnover boxes are full of goods, the limiting protrusion and positioning groove on the A long side plate of one logistics turnover box are respectively engaged with the positioning groove and limiting protrusion on the B long side plate of the other logistics turnover box. The other three side plates are handled in the same way to achieve staggered stacking. When the two logistics turnover boxes are empty, the limiting protrusion and limiting groove on the A long side plate of one logistics turnover box are respectively engaged with the limiting groove and limiting protrusion on the A long side plate of the other logistics turnover box. The other three side plates are handled in the same way to achieve stacking and storage.

[0007] Compared with existing technologies, the staggered stackable logistics turnover box of this utility model has an ingenious structural design. Each of its four side plates has a portion protruding outwards, forming a limiting groove on the inner side and a corresponding limiting protrusion on the outer side. Furthermore, the inner side also has a positioning groove that matches the limiting protrusion. The positioning grooves and limiting grooves on two oppositely distributed side plates are staggered. Therefore, when the logistics turnover box is full of goods, it can be stacked in a staggered manner through the interlocking of the positioning grooves and limiting protrusions. Multiple logistics turnover boxes stacked together have high stability and are not prone to sliding or collapsing. When the logistics turnover box is empty, multiple empty boxes can be nested together for storage through the interlocking of the limiting grooves and limiting protrusions, reducing storage volume, saving transportation space (approximately 30% reduction in storage space), and lowering transportation costs.

[0008] As an optimization, in the aforementioned staggerable stackable logistics turnover box, each of the A long side plate, A short side plate, B long side plate, and B short side plate is provided with two positioning grooves and two limiting protrusions at intervals. Thus, after the logistics turnover boxes are stacked in a staggered manner, the upper and lower boxes are connected and supported by eight positioning grooves and eight limiting protrusions. This improves stacking stability, preventing damage caused by shaking and collision during logistics transportation, and ensures that the lower box receives even force, thus avoiding damage due to excessive localized stress. Furthermore, a set of A reinforcing ribs is provided at intervals within the positioning grooves to increase their load-bearing capacity; the outer upper surfaces of the A long side plate, A short side plate, B long side plate, and B short side plate are provided with B reinforcing ribs in a cross shape to increase the overall strength of the upper part of the logistics turnover box. This prevents the upper part of the logistics turnover boxes from being damaged due to excessive stress after stacking.

[0009] As an optimization, in the aforementioned stackable logistics turnover box, the angles between the A long side plate, A short side plate, B long side plate, and B short side plate and the bottom plate are 85° to 88°. In this case, the four side plates are slightly tilted outwards, with the opening end larger than the bottom end, facilitating the stacking or nesting of the logistics turnover boxes. Furthermore, the positioning grooves, limiting grooves, and limiting protrusions on the four side plates are all trapezoidal in shape, wider at the top and narrower at the bottom. This facilitates the insertion of the limiting protrusions into the positioning grooves or limiting grooves.

[0010] As an optimization, in the aforementioned stackable logistics turnover box, handles are provided on the outer surfaces of the A and B short side panels, and the handles are provided with wavy ribs. When the logistics turnover box is handled manually, the fingers can fit against the wavy ribs, thereby increasing the anti-slip effect at the handle position.

[0011] As an optimization, in the aforementioned stackable logistics turnover box, the bottom plate is provided with C-shaped reinforcing ribs in a cross pattern. This increases the support strength of the entire bottom of the logistics turnover box. Furthermore, the thickness of the C-shaped reinforcing ribs located at the four edges can be 5-6 cm, and the thickness of the C-shaped reinforcing ribs located in the middle can be 3-4 cm.

[0012] As an optimization, in the aforementioned stackable logistics turnover box, the logistics turnover box can be integrally injection molded from polypropylene or polyethylene. In this case, the overall weight of the logistics turnover box is lighter, making it easier to handle, and it has higher strength and hardness, resulting in a longer service life. In addition, the logistics turnover box is easy to manufacture and has low processing costs due to injection molding. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings, but it should not be construed as a basis for limiting this utility model.

[0020] Example:

[0021] See Figure 1 and Figure 2 A stackable logistics turnover box includes a base plate 1 and four side plates A (long side plate 2), A (short side plate 3), B (long side plate 4), and B (short side plate 5) connected end-to-end on the base plate 1. The inner surfaces of the A (long side plate 2), A (short side plate 3), B (long side plate 4), and B (short side plate 5) are respectively provided with positioning grooves A (positioning groove 201), B (positioning groove 301), C (positioning groove 401), and D (positioning groove 501). Parts of the A (long side plate 2), A (short side plate 3), B (long side plate 4), and B (short side plate 5) protrude outwards, thereby forming limiting grooves A (limiting groove 202), B (limiting groove 302), C (limiting groove 403), and D (limiting groove 502) on the inner surfaces. A limiting protrusion 203, B limiting protrusion 303, C limiting protrusion 403, and D limiting protrusion 503 are formed on the surface respectively; the A positioning groove 201 and A limiting groove 202 are respectively offset from the C positioning groove 401 and C limiting groove 402; the B positioning groove 301 and B limiting groove 302 are respectively offset from the D positioning groove 501 and D limiting groove 502; the lower ends of the A limiting protrusion 203, B limiting protrusion 303, C limiting protrusion 403, and D limiting protrusion 503 are respectively adapted to the C positioning groove 401, D positioning groove 501, A positioning groove 201, and B positioning groove 301.

[0022] See Figure 4 When two logistics turnover boxes are filled with goods, the lower ends of the A limiting protrusion 203, B limiting protrusion 303, C limiting protrusion 403 and D limiting protrusion 503 on one of the logistics turnover boxes are respectively inserted into the C positioning groove 401, D positioning groove 501, A positioning groove 201 and B positioning groove 301 on the other logistics turnover box to achieve staggered stacking.

[0023] See Figure 5 When both logistics turnover boxes are empty, the A-limiting protrusion 203, B-limiting protrusion 303, C-limiting protrusion 403, and D-limiting protrusion 503 on one logistics turnover box are respectively inserted into the A-limiting groove 202, B-limiting groove 302, C-limiting groove 402, and D-limiting groove 502 on the other logistics turnover box, achieving stacking and storage. In this embodiment, the height H1 of the logistics turnover boxes is 330 mm, and the stacking height H2 of the empty boxes is 120 mm. After stacking, the storage space is reduced by 30%, saving transportation costs.

[0024] In this embodiment, the inner surfaces of the A long side plate 2, A short side plate 3, B long side plate 4, and B short side plate 5 are all provided with two positioning grooves and two limiting grooves at intervals. After the logistics turnover boxes are stacked in a staggered manner, the upper and lower boxes are connected and supported by eight positioning grooves and eight limiting protrusions. This can improve the stacking stability and prevent damage caused by shaking and collision of the logistics turnover boxes during logistics transportation. On the other hand, it can make the lower box bear the force evenly, thereby avoiding damage due to excessive local force. Specifically, on the A long side plate 2, two A positioning grooves 201 are located on both sides of two A limiting grooves 202; on the B long side plate 4, two C limiting grooves 402 are located on both sides of two C positioning grooves 401; on the A short side plate 3, two B positioning grooves 301 are located on both sides of two B limiting grooves 302; and on the B short side plate 4, two D limiting grooves 502 are located on both sides of two D positioning grooves 501.

[0025] Furthermore, the positioning groove is provided with three 2.5mm thick A reinforcing ribs 6 at intervals to increase the stress resistance of the positioning groove; the outer upper surfaces of the A long side plate 2, A short side plate 3, B long side plate 4, and B short side plate 5 are provided with cross-shaped B reinforcing ribs 7 to increase the overall strength of the upper part of the logistics turnover box; thus, it can prevent the upper part of the logistics turnover box from being damaged due to excessive stress after stacking. The reinforcing ribs are trapezoidal in shape, wider at the bottom and narrower at the top.

[0026] In this embodiment, the angle between the A long side plate 2, A short side plate 3, B long side plate 4, and B short side plate 5 and the base plate 1 is 88°. At this angle, the four side plates are slightly tilted outwards, with the opening end larger than the bottom end, facilitating the stacking or nesting of the logistics turnover boxes; moreover, demolding is easier after the logistics turnover boxes are injection molded. Furthermore, the positioning grooves, limiting grooves, and limiting protrusions on the four side plates are all trapezoidal in shape, wider at the top and narrower at the bottom. This facilitates the insertion of the limiting protrusions into the positioning grooves or limiting grooves.

[0027] In this embodiment, handles are provided on the outer surfaces of the A short side plate 3 and the B short side plate 5, and the handles are provided with wavy ribs 8. When the logistics turnover box is manually handled, the fingers can fit against the wavy ribs 8, thereby increasing the anti-slip effect at the handle position and allowing the staff to better grip the handles on both sides.

[0028] See Figure 3 In this embodiment, the bottom of the base plate 1 is provided with C-reinforcing ribs 9 arranged in a cross shape. This increases the supporting force of the entire bottom of the logistics turnover box. Furthermore, the thickness of the C-reinforcing ribs 9 located at the four edges is 5cm, and the thickness of the C-reinforcing ribs 9 located in the middle is 3cm.

[0029] In this embodiment, the logistics turnover box is integrally injection molded from polypropylene. This results in a lighter overall weight, making it easier to handle, while also providing higher strength and rigidity, leading to a longer service life. Furthermore, the injection molding process makes the logistics turnover box easy to manufacture and reduces processing costs.

[0030] The foregoing general description of the utility model and its specific embodiments should not be construed as limiting the technical solution of the utility model. Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this utility model.
