[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0038] like Figure 1-8 As shown, this embodiment discloses a storage box assembly, including a lower storage box 1, a first upper storage box 2, and a second upper storage box 3. The upper surface of the lower storage box 1 has an opening, forming an internal storage space for storing items. Specifically, two rows of three positioning pins 11 are symmetrically arranged on both sides of the opening of the lower storage box 1, with the three positioning pins 11 on the left and right sides arranged symmetrically. The positioning pins 11 serve a guiding and fixing function, ensuring that the subsequently assembled upper storage boxes can be accurately positioned and securely connected.

[0039] Combination Figure 5 As shown, the lower storage box 1 has columnar first supports 12 at its four corners. The lower end of each first support 12 has a groove into which the positioning pin 11 can be inserted, thus enabling the lower storage boxes 1 to be vertically connected through the first supports 12 and the positioning pin 11. With this structure, multiple lower storage boxes 1 can be stacked and connected, enhancing the stability of the overall structure and saving space.

[0040] Combination Figure 1 As shown, the first upper storage box 2 and the second upper storage box 3 are arranged side by side to form a parallel assembly. Both have columnar second supports 21 at their lower ends, with grooves at the bottom to engage with the positioning posts 11 along the opening edge of the lower storage box 1. Specifically, the second support 21 on the outer side of the first upper storage box 2 is inserted into the positioning post 11 on the left side edge of the lower storage box 1, and the second support 21 on the outer side of the second upper storage box 3 is inserted into the positioning post 11 on the right side edge of the lower storage box 1. Through the cooperation of the supports and the positioning posts 11, precise assembly and stable support of the upper and lower storage boxes 1 are achieved, preventing them from falling off or shifting due to vibration or movement.

[0041] The lower storage box 1 has six notches 18 along its opening edge, and six positioning pins 11 are correspondingly placed in the notches 18. This notch 18 structure facilitates injection molding and improves the fit and stability during insertion, thereby enhancing the firmness of the connection between the upper and lower boxes.

[0042] Combination Figure 8 As shown, the lower storage box 1 has corresponding lateral grooves 13 on both sides, and the lateral grooves 13 and the positioning pins 11 are staggered in the horizontal direction. This allows the first upper storage box 2 and the second upper storage box 3 to be stacked and spliced ​​by interlocking the lateral grooves 13, so that the two lower storage boxes 1 can be effectively stacked in space, saving volume and facilitating transportation and storage.

[0043] When in use, if the two lower storage boxes 1 are stacked one on top of the other and aligned front to back, the first support 12 of the upper lower storage box 1 can be inserted into the groove positioning post 11 of the lower lower storage box 1 to achieve a stable connection; if the two lower storage boxes 1 are stacked one on top of the other but slightly offset front to back, the concave and convex structures of the two boxes can fit together and align, which can also achieve a stable stacking effect.

[0044] The lower storage box 1 has a lateral insertion post 14 on one side and a matching lateral slot 16 on the other side. Multiple lower storage boxes 1 can be inserted into the lateral slots 16 of adjacent lower storage boxes 1 through the lateral insertion post 14 to achieve left-right splicing. This insertion method has a compact structure, stable splicing, and is easy to disassemble and reassemble.

[0045] Combination Figure 3-6 As shown, both the first upper storage box 2 and the second upper storage box 3 are equipped with lateral insertion posts 14 and lateral slots 16. This structure enables left-right splicing connections between them, enhancing modular splicing capabilities and combination flexibility. The lateral insertion post 14 is provided with a first reinforcing rib 15 extending along the insertion direction. This first reinforcing rib 15 enhances the mechanical strength of the lateral insertion post 14 and improves the durability of the connection part. A second reinforcing rib 17 is provided between the lateral slot 16 and the lower storage box 1 body, effectively improving the overall rigidity of the connection between the slot area and the box body and preventing deformation during use. The lateral insertion post 14 is provided with a positioning protrusion 16a, and the corresponding position of the lateral slot 16 is provided with a positioning groove (not shown in the figure) adapted to the positioning protrusion 16a, realizing positioning indication during the splicing process, preventing misalignment during insertion, and improving the accuracy of assembly. The lateral insertion post 14 includes a platform portion 14a perpendicular to the insertion direction and an insertion post portion 14b parallel to the insertion direction, wherein the insertion post portion 14b is formed by protrusion of the platform portion 14a.

[0046] Specifically, the way the positioning pin 11 is combined with the groove at the lower end of the first support 12 and the second support 21 makes the insertion process mechanically convenient and highly secure; the cooperation between the first support 12 at the lower end of the lower storage box 1 and the positioning pin 11 enables the upper and lower stacking connection of multiple lower storage boxes 1, enhancing overall stability; and in the horizontal direction, the side pin 14 / slot structure ensures the compactness and stability of the left and right assembly.

[0047] In this embodiment, the first upper storage box 2 and the second upper storage box 3 have the same shape and size; in other embodiments, they may have the same shape but different sizes to meet different storage capacities or modular requirements.

[0048] Through the structural design provided in this embodiment, this storage box assembly achieves stable splicing and positioning between multiple boxes, ensuring the overall structural strength and safety during use. The splicing method is simple and clear, and assembly is convenient, suitable for injection molding mass production and free on-site combination. At the same time, the use of side grooves 13 and plug-in structure effectively saves stacking volume, facilitates transportation and storage, and enhances the product's practicality and market competitiveness.
