[0004] However, the following problems still exist in actual use:

[0005] (1) When in use, the assembly of the box is achieved by the cooperation of the fixing hole and the fixing ball. This connection method is prone to loosening or falling off when subjected to large external forces, resulting in insufficient stability of the box structure and affecting its reliability in actual use. The box is folded by the rotating rod mechanism, but in actual operation, due to the complexity of the rotating rod mechanism, the user still needs to make multiple adjustments and fixation during the folding process, which makes the folding process inconvenient and time-consuming.

[0006] (2) When in use, the first partition and the second partition are fixedly connected to the upper surface of the bottom plate, which makes it impossible to flexibly adjust the internal storage space of the packaging box according to actual needs. When it is necessary to store items of different sizes or quantities, the fixed partition design limits the applicability of the packaging box and cannot meet diverse storage needs.

[0007] Therefore, this utility model introduces a plastic packaging box that is easy to fold. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 3 and Figure 5 A foldable plastic packaging box includes a base plate 1, a first side plate 5, and a second side plate 8. A folding assembly mechanism 18 is provided inside the second side plate 8. The folding assembly mechanism 18 includes a snap-fit ​​block 9, a connecting spring 10, a telescopic rod 11, a rubber pad 12, and a limiting rod 13. The right side of the snap-fit ​​block 9 is fixedly connected to the left side of the first side plate 5. One end of the connecting spring 10 is fixedly installed inside the second side plate 8. One end of the telescopic rod 11 is fixedly installed inside the second side plate 8. The bottom of the rubber pad 12 is fixedly connected to the other end of the connecting spring 10, and the bottom of the rubber pad 12 is fixedly connected to the other end of the telescopic rod 11. The limiting rod 13... One end of rod 13 is fixedly installed to the top of rubber pad 12. The outer surface of snap-fit ​​block 9 is snapped into the inside of second side plate 8, and the inside of snap-fit ​​block 9 is snapped into the outer surface of limit rod 13. The outer surface of limit rod 13 is snapped into the inside of second side plate 8. A first fixing block 3 is fixedly installed on the upper surface of base plate 1. A first rotating shaft 4 is fixedly installed inside the first fixing block 3. The outer surface of the first rotating shaft 4 is rotatably connected to the inside of first side plate 5. A second fixing block 6 is fixedly installed on the upper surface of base plate 1. A second rotating shaft 7 is fixedly installed inside the second fixing block 6. The outer surface of the second rotating shaft 7 is rotatably connected to the inside of second side plate 8.

[0027] Specifically, the combination of the base plate 1, the first side plate 5, and the second side plate 8 achieves the effect of constructing the basic frame of the plastic packaging box, enabling the whole to bear and protect the internal items after assembly. Through the cooperation of the first fixing block 3 and the second fixing block 6 with the first rotating shaft 4 and the second rotating shaft 7, the first side plate 5 and the second side plate 8 can rotate flexibly relative to the base plate 1, which facilitates the folding and unfolding of the packaging box and improves the convenience of use. Through the synergistic effect of the snap-fit ​​block 9, the connecting spring 10, the telescopic rod 11, the rubber pad 12, and the limiting rod 13 in the folding assembly mechanism 18, the first side plate 5 and the second side plate 8 can be firmly snapped together when the packaging box is folded, preventing them from loosening. At the same time, the rubber pad 12 increases the cushioning and sealing of the contact, protecting the edges of the packaging box from damage.

[0028] Please see Figure 4The upper surface of the base plate 1 is provided with a space adjustment mechanism 19. The space adjustment mechanism 19 includes a fixed baffle 14, a sleeve plate 15, a rectangular block 16 and a U-shaped locking block 17. The bottom of the fixed baffle 14 is fixedly installed with the top of the base plate 1. The outer surface of the sleeve plate 15 is sleeved with the inside of the fixed baffle 14. The bottom of the rectangular block 16 is fixedly installed with the top of the sleeve plate 15. The right side of the U-shaped locking block 17 is fixedly installed with the left side of the first side plate 5, and the inside of the U-shaped locking block 17 is locked with the outer surface of the rectangular block 16.

[0029] Specifically, the socket plate 15's outer surface and the fixed baffle 14's inner surface are designed to fit together, allowing the socket plate 15 to move flexibly within the fixed baffle 14. This enables height adjustment of the rectangular block 16 and its connected components, meeting the different height requirements of various items for the internal space of the packaging box. The right side of the U-shaped card block 17 is fixedly installed on the left side of the first side plate 5, and the U-shaped card block 17's inner surface is designed to fit together with the outer surface of the rectangular block 16, achieving a stable effect after adjusting the height.

[0030] Please see Figure 1 and Figure 2 The first side plate 5 has a handle groove 2 inside, the bottom of the first side plate 5 is attached to the top of the base plate 1, and the bottom of the second side plate 8 is attached to the top of the base plate 1.

[0031] Specifically, the handle groove 2, located inside the first side panel 5, facilitates the user's grip and movement of the entire packaging box. The ergonomic design of the handle groove 2 makes it easier and less strenuous for users to handle or move the packaging box, improving convenience and comfort.

[0032] Working principle: During use, when assembling, folding, or disassembling the whole assembly, disassembly can begin by pressing the rubber pad 12, lowering the position of the limiting rod 13 fixed on the upper surface of the rubber pad 12, and disengaging the limiting rod 13 from the snap-fit ​​block 9 and the interior of the second side plate 8. Then, through the function of the first fixing block 3 and the second fixing block 6 fixed on the upper surface of the base plate 1, and the connection function of the first rotating shaft 4 and the second rotating shaft 7 fixed inside the first fixing block 3 and the second fixing block 6, the positions of the first side plate 5 and the second side plate 8 can be rotated. Rotating the first side plate 5 and the second side plate 8 to a position parallel to the base plate 1 allows for the disassembly operation of the whole assembly. When assembling the whole assembly... The positions of the first side plate 5 and the second side plate 8 can be rotated by the action of the first fixing block 3, the first rotating shaft 4, the second fixing block 6, and the second rotating shaft 7. During rotation, the position of the locking block 9 fixed on the left side of the first side plate 5 is locked with the inside of the second side plate 8, thus initially limiting the assembly between the first side plate 5 and the second side plate 8. Afterwards, the rubber pad 12 can be loosened. Through the rebound force of the spring 10 and the telescopic rod 11 fixedly installed between the rubber pad 12 and the inside of the second side plate 8, the limiting rod 13 can be locked with the inside of the second side plate 8 and the locking block 9, thus limiting the assembly of the first side plate 5 and the second side plate 8 again and ensuring their stability during assembly and use.

[0033] When changing the internal space after assembly, the position of the socket plate 15 can be moved upward by the function of the internal socket plate 15 of the fixed baffle 14. By driving the position of the rectangular block 16 fixed on the upper surface of the socket plate 15 to move upward synchronously, the outer surface of the rectangular block 16 is engaged with the inside of the U-shaped card block 17, which limits the position of the socket plate 15 after it moves upward, and ensures the stability of the internal space after assembly.

[0034] It should be noted that the electrical components and electrical equipment mentioned above are all connected to an external power source through a controller, and can be driven by an external power source. The circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated.
