[0021] The following is in conjunction with the appendix Figure 1-5 The accompanying drawings provide a further detailed description of this application. The technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] This application discloses a paper packaging box. For example... Figure 1 As shown, the package includes an outer shell 1. Two cardboard doors 6 are fixedly connected to the upper surface of the outer shell 1. These cardboard doors 6 can be flexibly flipped along the connecting edges on the outer shell 1, allowing for convenient opening and closing of the packaging box. An inner shell 2 is nested inside the outer shell 1, forming a double-layered nested structure. This enhances the overall structural strength of the packaging box and provides double protection for the contents. It also provides space for the installation of a shock-absorbing structure. A buffer pad 3 is snapped between the inner bottom wall of the outer shell 1 and the bottom surface of the inner shell 2. This buffer pad 3 effectively absorbs the impact force transmitted from the bottom, providing bottom cushioning protection for the inner shell 2 and the contents. Four slots 4 are provided on the inner wall of the outer shell 1. These slots 4 facilitate the installation of the bending partition 5. Multiple adjustable connection points are provided to facilitate flexible adjustment of the partition structure according to needs. The inner shell 2 has two bent partitions 5 inside. The bent partitions 5 can rotate freely along the folding groove 10 and then be installed in different positions of the slots 4 to flexibly form cross-shaped or parallel space partitions to adapt to the placement needs of items of different sizes. The two bent partitions 5 are respectively snapped into the slots 4 opened on two adjacent sides of the outer shell 1. The inner side wall of the inner shell 2 has a first fixing groove 12 and the outer surface of the bent partitions 5 has two second fixing grooves 11. The two can be used to snap into the partitions 13 to further refine the internal space and greatly improve the flexibility and adaptability of the packaging box space utilization.

[0023] Please see Figure 2Both the first fixing groove 12 and the second fixing groove 11 are fitted with partitions 13. The partitions 13 are fitted into the first fixing groove 12 and the second fixing groove 11. This not only further refines the internal space of the inner shell 2, allowing items of different sizes to fit in and avoiding collisions, but also enhances the stability of the overall structure by connecting the inner shell 2 with the bent partitions 5, reducing the displacement of components during transportation or handling, and improving the reliability of the packaging.

[0024] Please see Figure 1 A first buffer plate 8 is snapped between the inner wall of the outer shell 1 and the outer surface of the inner shell 2, which is convenient for disassembly and adjustment. It fills the gap between the outer shell 1 and the inner shell 2 and can effectively absorb the impact force transmitted from the side during transportation or handling.

[0025] Please see Figure 1 A second buffer plate 9 is snapped between the inner wall of the outer shell 1 and the outer surface of the inner shell 2. The second buffer plate 9 can work together with the first buffer plate 8 and the bottom buffer pad 3 to form a protective effect, further enhancing the cushioning protection effect of the packaging box on the internal items, reducing the possibility of damage to the items due to lateral collisions, and making the packaging protection more comprehensive and reliable.

[0026] Please see Figure 4 The bottom surface of the bent partition 5 is provided with a clearance groove 7. The clearance groove 7 is used to avoid structural interference when installing with another bent partition 5, ensuring that the bent partition 5 does not obstruct other components when assembled, and further improving the reliability of the packaging structure.

[0027] Please see Figure 4 The bottom surface of the bending partition 5 is provided with a folding groove 10, which is set along the length of the bending partition 5, conforming to the folding characteristics of paper materials. With the help of the folding groove 10, the bending partition 5 can easily achieve bending deformation at a preset angle.

[0028] The implementation principle of a paper packaging box according to an embodiment of this application is as follows: The outer shell 1 serves as the main supporting structure, with cardboard doors 3 fixedly connected to both its upper and lower sides. The cardboard doors 3 can be flipped along the connecting edges to open and close the packaging box. An inner shell 2 is provided inside the outer shell 1, and slots 4 are evenly distributed on the inner sidewall of the inner shell 2. The slots 4 are at the same height as the interior of the inner shell 2, used to accommodate the installation of bent partitions 5, providing adjustable installation points for the bent partitions 5. Two partitions 5 can form a cross-shaped or parallel partition by being snapped into different slots 4. Combined with the bent partitions 5, they can be folded and deformed along the folding grooves 7, flexibly adapting to the placement needs of items of different sizes. The surfaces of the partition 5 and the inner shell 2 are respectively provided with a second fixing groove 11 and a folding groove 10. The partition 13 is snapped into the second fixing groove 11 and the folding groove 10, which further increases the space utilization efficiency of the packaging box. At the same time, the compact space can prevent the items from shaking during transportation. The cushioning pad 3, the first cushioning plate 8 and the second cushioning plate 9 together constitute the shock absorption mechanism of the packaging box, ensuring the safety of the packaging box during transportation. Meanwhile, the internal structure of the packaging box is a detachable structure. For example, the cushioning pad 3, the bending partition 5, the first cushioning plate 8, the second cushioning plate 9 and the partition 13 can all be stored together with the packaging box as a whole and installed as needed during actual work.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
