[0002] Cardboard packaging is a common packaging material. It has good protective performance and aesthetics and is widely used in the packaging of various commodities. This type of packaging box is usually made of multiple layers of cardboard and can be printed with exquisite patterns or texts on the outside. It is very suitable for enhancing the grade of the product. Depending on the purpose, cardboard packaging boxes can be designed into various shapes and sizes, such as rectangular, cube or more complex special-shaped structures.

[0003] In the prior art, the existing rigid packaging box cartons have been designed to be relatively thick, but their ability to withstand lateral and vertical pressure is still not strong enough. In this regard, the utility model with publication number CN214649762U proposes "a recyclable packaging carton with internal support to prevent extrusion deformation". It supports the carton by arranging structures such as protrusions, push barrels, moving rods and threaded rods inside the carton. Although it can prevent the carton from being squeezed and deformed, the support structure is too complicated, resulting in high production costs and is also troublesome to install. At the same time, it cannot be properly adjusted to adapt to rigid paper box packaging boxes of different sizes. For this reason, the utility model proposes an internal support pressure-resistant structure and a rigid paper packaging box to solve the above problems. Utility Model Content

[0023] Example 1: Please refer to Figures 1 to 4 The utility model provides a technical solution: an internal support pressure-resistant structure and a hard paper packaging box, comprising: a main rod 1, a sleeve 2 is threadedly connected at both ends of the main rod 1, a fixing clamp 3 is fixedly sleeved on the outer ring surface of one end of the sleeve 2, a fastening sleeve 4 is threadedly connected on the outer ring surface of the fixing clamp 3, an extension tube 5 is slidingly sleeved in the sleeve 2, an adjusting rod 6 is movably connected to one end of the extension tube 5, the adjusting rod 6 is slidingly sleeved in the side support 7, a side support plate 8 is fixedly connected to one side of the adjusting rod 6, a vertical support plate 9 is provided on the upper side of the side support plate 8, the bottom of the vertical support plate 9 is movably connected to the connecting rod 10, the two ends of the connecting rod 10 are movably connected to the bent rod 11, and the two ends of the bent rod 11 are movably connected to the top of the adjusting rod 6.

[0024] When the container is in a state of being stretched, the fixing parts 5 of the fixing parts 1 are tightened, and the fixing parts 5 of the fixing parts 1 are tightened, so that the fixing parts 5 of the fixing parts 1 are tightened.

[0025] Embodiment 2: On the basis of embodiment 1, one end of the extension tube 5 is slidably sleeved in the sleeve 2, and the other end of the extension tube 5 is fixedly connected with a cross block 12. A cross groove 13 is provided on one side of the outer ring surface of the side pillar 7 and the adjusting rod 6. The extension tube 5 is slidably installed in the sleeve 2 and is limited by the sleeve 2. The outer end of the extension tube 5 is fixedly connected with a cross block 12. The cross block 12 and the outer ring surface of the side pillar 7 and the adjusting rod 6 are slidably connected. The cooperation between the cross groove 13 and the cross block 12 can make the clamping more stable. The cross groove 13 and the cross block 12 are slidably connected. The adjusting rod 6 is symmetrically sleeved in the upper and lower parts of one side pillar 7, the side support plate 8 is slidably connected to one side of the side pillar 7, and the stabilizing rod 16 is slidably inserted at the bottom of the side pillar 7. The adjusting rod 6 is symmetrically arranged in the upper and lower parts of one side pillar 7, so as to facilitate the extension of the side pillar 7.

[0026] By holding the middle of the main rod 1 and twisting the sleeves 2 threaded on both sides, the main rod 1 can be appropriately extended, and then the extension tube 5 slidingly sleeved in the sleeve 2 can be pulled out to further extend the main rod 1, so as to facilitate adjustment when supporting packaging boxes of different sizes. After the extension tube 5 is pulled out, the cross block 12 at one end thereof is slidably connected with the cross groove 13 provided on the outer ring surface of the side pillar 7 and the adjusting rod 6. On the one hand, the cross groove 13 provided on the side pillar 7 is used to facilitate adjustment of the installation height of the main rod 1. On the other hand, the cross groove 13 provided on the adjusting rod 6 is slidably connected with the cross block 12, so as to facilitate adjustment of the extending height of the adjusting rod 6 in the side pillar 7. At the same time, the adjusting rod 6 is limited, which further improves the flexibility of use and better adapts to different For packaging boxes of the same size, a stabilizing rod 16 is slidably inserted between the two side pillars 7. The length of the stabilizing rod 16 can be adjusted according to the distance between the side pillars 7. Therefore, the stability of the support of the side pillars 7 is increased by the setting of the stabilizing rod 16. After the adjustment of the extension tube 5 and the adjusting rod 6 is completed, the fastening sleeve 4 is rotated, and the fastening sleeve 4 is threadedly connected to one end of the fixing clamp 3. The other end of the fixing clamp 3 is provided with a forked conical surface, and its conical surface cooperates with the inner conical surface of the fastening sleeve 4. Therefore, under the tightening action of the fastening sleeve 4, the forked end of the fixing clamp 3 is contracted, thereby clamping the outer ring surface of the extension tube 5, fixing the extension tube 5, and then fixing the extension tube 5. The side pillar 7 is fixedly connected to the side support plate 8, thereby increasing the lateral compressive strength of the packaging box by the setting of the side pillar 7 and the side support plate 8.

[0027] Embodiment 3: On the basis of embodiment 2, a hexagonal hole 14 is provided on the top of the adjusting rod 6, and a hexagonal block 15 is fixedly connected to the bottom of both ends of the bent rod 11. The hexagonal block 15 and the hexagonal hole 14 are slidably inserted through the hexagonal hole 14 opened at the top of the adjusting rod 6, so as to facilitate the insertion of the hexagonal block 15 at the bottom of the bent rod 11. A large limiting hole 17 is provided on the outer ring surface of the bent rod 11, and a small limiting hole 18 is provided on the outer ring surface of the connecting rod 10. The two ends of the connecting rod 10 are slidably inserted into the large limiting hole 17, and one end of the fixing rod 19 is slidably inserted in the small limiting hole 18, and the other end of the fixing rod 19 is threadedly connected to the vertical support plate 9. The large limiting hole 17 opened on the bent rod 11 facilitates the installation of the connecting rod 10, and the small limiting hole 18 opened on the connecting rod 10 facilitates the installation of the fixing rod 19. The fixing rod 19 is threadedly connected to the vertical support plate 9, thereby facilitating the disassembly between the vertical support plate 9 and the fixing rod 19.

[0028] After the height of the adjusting rod 6 is installed by the sliding fit of the cross block 12 and the cross slot 13, the hexagonal hole 14 opened on the top of the adjusting rod 6 is fixedly connected to the hexagonal block 15 at the end of the bent rod 11, so as to fix the bent rod 11 on one side first, and then insert one end of the connecting rod 10 into the large limiting hole 17 opened on the side of the bent rod 11, and insert the other end of the connecting rod 10 into the bent rod 11 on the other side, and then insert and install the bent rod 11 on the other side, so as to fix the connecting rod 10 through the bent rod 11. Then, one end of the fixing rod 19 is threadedly connected to the lower surface of the vertical support plate 9, and the items are placed between the main rods 1. Then, the fixing rod 19 is inserted into the small limiting hole 18 opened on the connecting rod 10, so as to complete the installation of the vertical support plate 9. The size of the vertical support plate 9 can be adjusted according to the size of the packaging box. Finally, the entire device is stably placed in the packaging box, so that the vertical pressure resistance of the packaging box can be increased by setting the vertical support plate 9.
