[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-8 A pressure-resistant packaging box that is easy to assemble and disassemble includes a base plate 1 and a lid 2. The upper end of the base plate 1 is rotatably connected to two first side plates 3 and two second side plates 4. The base plate 1, lid 2, first side plates 3 and second side plates 4 are all made of materials with high strength, toughness and corrosion resistance, which can withstand a certain pressure without deformation or damage, thus providing basic pressure resistance for the packaging box. Magnets or magnetic materials are installed at the contact points between the lid 2 and the first side plates 3 or the second side plates 4, and the lid 2 is attracted to the side plates by magnetic force. This connection method can make the lid 2 open and close more smoothly, and can provide a certain degree of sealing when closed. Two fixed plates 5 are fixedly connected to the opposite sides of the two second side plates 4. Each fixed plate 5 has a moving groove 6. Each moving groove 6 has a telescopic rod 7 installed on its inner wall. Each telescopic rod 7 has a moving plate 8 fixedly connected to its telescopic end. Two strip openings 9 are opened on the opposite sides of the two second side plates 4. The other end of each moving plate 8 passes through the corresponding strip opening 9 and extends to the outside.

[0026] Each telescopic rod 7 has a first spring 10 fitted on its outer wall. Both ends of each first spring 10 are elastically connected to the inner wall of the corresponding moving groove 6 and one side wall of the moving plate 8, respectively. The other side wall of each moving plate 8 is fixedly connected to a plug plate 11. Two slots 12 that cooperate with the corresponding plug plates 11 are opened on the opposite sides of the two first side plates 3. Through the cooperation of the telescopic rod 7, the first spring 10 and the plug plate 11, the second side plate 4 and the first side plate 3 can be easily connected and separated. During installation, the plug plate 11 is inserted into the slot 12. During disassembly, the plug plate 11 is pulled out of the slot 12 by overcoming the elastic force of the first spring 10. Two fixing covers 13 are fixedly connected to the opposite sides of the two first side plates 3. Threaded rods 14 are rotatably connected between the inner walls of the two sides of each fixing cover 13. One end of each threaded rod 14 extends to the outside and is fixedly connected to a knob 15. Each knob 15 is provided with a rubber layer.

[0027] Each threaded rod 14 is threadedly connected to a sliding plate 16, one end of which extends to a corresponding slot 12. A limiting block 17 is fixedly connected to the side wall of each sliding plate 16. Each insert plate 11 has a limiting groove 18 on its side wall that mates with the corresponding limiting block 17. Rotating the knob 15 causes the threaded rod 14 to rotate, allowing the limiting block 17 on the sliding plate 16 to insert into or remove from the limiting groove 18 on the insert plate 11, further securing or releasing the connection between the insert plate 11 and the slot 12, thus increasing the connection... The stability and ease of operation are achieved through this structural design, which makes the various parts of the packaging box tightly connected. This design can disperse external pressure to a certain extent, improve the overall pressure resistance, and better protect the contents. A partition plate 19 is provided at the upper end of the bottom plate 1. Two sliding grooves 20 are provided in the partition plate 19. A rotating groove 21 is provided in the partition plate 19. Both sliding grooves 20 are connected to the rotating groove 21. Sliding blocks 22 are slidably connected to the inner walls of both sliding grooves 20. Rectangular blocks 23 are fixedly connected to the opposite sides of the two sliding blocks 22.

[0028] Each of the two first side plates 3 has multiple rectangular slots 24 on opposite sides that mate with the corresponding rectangular blocks 23. Each of the two sliders 22 has a pull rope 25 fixedly connected to its opposite sides. Each of the two sliders 22 has its opposite sides elastically connected to the inner wall of the corresponding slide groove 20 via a second spring 26. The other ends of the two pull ropes 25 pass sequentially through the corresponding slide groove 20 and the rotating groove 21, extending to the outside. The other ends of the two pull ropes 25 are fixedly connected via a pull rod 27. By pulling the pull rod 27, the slider 22 slides within the slide groove 20, thus moving the rectangular blocks. 23 can be disengaged from the rectangular groove 24, allowing the position of the divider 19 to be adjusted to accommodate items of different sizes and improve the practicality of the packaging box. The inner wall of the rotating groove 21 is rotatably connected to two rotating shafts 28, and the outer walls of the two rotating shafts 28 are fixedly connected to guide wheels 29. The two guide wheels 29 cooperate with the corresponding pull ropes 25. The function of the guide wheels 29 is to change the direction of movement of the pull ropes 25, making the pulling of the pull ropes 25 smoother, reducing friction, and ensuring that the pull ropes 25 do not deviate from the predetermined trajectory during movement.

[0029] In this utility model, when in use, the base plate 1 is first placed, and then the two second side plates 4 are rotated to the appropriate position. At this time, the telescopic rod 7 is in a natural state. Under the action of the first spring 10, the moving plate 8 drives the insert plate 11 to extend outward. Then, the two first side plates 3 are rotated so that the slot 12 on the first side plate 3 is aligned with the insert plate 11 on the second side plate 4. The insert plate 11 is inserted into the corresponding slot 12, realizing the initial connection between the first side plate 3 and the second side plate 4. Then, the knob 15 is rotated, and the knob 15 drives the threaded rod 14 to rotate, so that the sliding plate 16 moves along the threaded rod 14. The limiting block 17 moves accordingly and is inserted into the limiting groove 18 on the insert plate 11, thereby fixing the insert plate 11 in the slot 12, realizing the stable connection between the first side plate 3 and the second side plate 4, forming the main frame of the packaging box.

[0030] When it is necessary to divide the internal space of the packaging box, the divider plate 19 can be used. Under the elastic action of the second spring 26, the slider 22 causes the rectangular block 23 to extend outward and insert into the rectangular groove 24, thereby fixing the divider plate 19 between the two first side plates 3 to achieve the division of the internal space of the packaging box. If it is necessary to adjust the position of the divider plate 19 or remove the divider plate 19, pull the pull rod 27. The pull rod 27 drives the pull rope 25 to move. The pull rope 25 pulls the slider 22 to move inward against the elastic force of the second spring 26, so that the rectangular block 23 exits from the rectangular groove 24. In this way, the divider plate 19 can be moved or removed. After completing the division of the side and internal space (if necessary), the box cover 2 is placed on the assembled packaging box to complete the assembly of the entire packaging box.

[0031] During disassembly, first rotate the knob 15 in the opposite direction to allow the limiting block 17 to exit from the limiting groove 18 of the insert plate 11. Then, pull the moving plate 8 to move the insert plate 11 out of the slot 12, thereby disengaging the connection between the first side plate 3 and the second side plate 4. Then, lower the first side plate 3 and the second side plate 4 around the rotating connection part with the base plate 1 to complete the disassembly of the packaging box, making it convenient for storage.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
