[0025] Specifically, the upper box cover 2 drives the sealing frame 4 to slide on the inner wall of the inner groove 3 opened on the upper surface of the packaging box body 1 to form a seal on the packaging box body 1. The sealing strip 13 can further improve the sealing effect of the packaging box body 1 after installation. The circular groove 5 can be used to provide sliding space for the circular slider 6, and the limiting groove 10 is used to limit the pull column 12. After the sealing strip 13 is installed, the pull column 12 can be pulled to cause the pull column 12 to slide on the inner wall of the limiting groove 10, so that the circular groove 5 drives the card block 11 to slide out from the inner wall of the card groove 15 opened on the outer wall of the L-shaped connecting block 14, and then the disassembly of the sealing strip 13 can be completed.

[0026] Reference Figure 1 and Figure 4 , the inner wall of the packaging box body 1 is slidably connected with a first partition plate 16, the outer wall of the first partition plate 16 is provided with a first fixing groove 17, and the outer wall of the first partition plate 16 is provided with a second fixing groove 18; the inner wall of the packaging box body 1 is slidably connected with a second partition plate 19, the outer wall of the second partition plate 19 is slidably connected to the inner wall of the first fixing groove 17, the inner wall of the packaging box body 1 is slidably connected with a third partition plate 20, and the outer wall of the third partition plate 20 is slidably connected to the inner wall of the second fixing groove 18; the lower surface of the upper box cover 2 is affixed with a fixing block 21, the lower surface of the fixing block 21 is provided with a first rectangular groove 22, the lower surface of the fixing block 21 is provided with a second rectangular groove 23, and the first rectangular groove 22 and the second rectangular groove 23 are connected to each other;

[0027] Specifically, the first fixing groove 17 opened on the outer wall of the first partition plate 16 is used to provide a space for installing the second partition plate 19 , and the second fixing groove 18 opened on the outer wall of the first partition plate 16 is used to provide a space for installing the third partition plate 20 .

[0028] Reference Figure 1 and Figure 4 , the outer wall of the first partition plate 16 is slidably connected to the inner wall of the first rectangular groove 22; the outer wall of the third partition plate 20 is slidably connected to the outer wall of the second rectangular groove 23; the outer wall of the second partition plate 19 is slidably connected to the inner wall of the second rectangular groove 23;

[0029] Specifically, during the downward movement of the fixed block 21, the second fixed groove 18 and the third partition plate 20 will slide in the inner wall of the second rectangular groove 23 opened on the lower surface of the fixed block 21, and at the same time, the outer wall of the first partition plate 16 will slide in the inner wall of the first rectangular groove 22 opened on the lower surface of the fixed block 21.

[0030] Working principle: When the packaging box needs to be used, the upper box cover 2 drives the sealing frame 4 to slide on the inner wall of the inner groove 3 to seal the entire packaging box. When it is necessary to install the sealing strip 13 to further improve the sealing effect, the sealing strip 13 slides on the outer wall of the upper box cover 2 and the packaging box body 1. At this time, the sealing strip 13 will drive the L-shaped connecting block 14 to contact the card block 11 and slide on the outer wall of the card block 11. In the process of the L-shaped connecting block 14 sliding on the outer wall of the card block 11, the card block 11 will be forced to push the connecting column 9 to move, thereby causing the connecting column 9 to drive the circular slider 6 to slide on the inner wall of the circular groove 5 and prompt the spring 8 is stressed and contracts. When the card block 11 slides to the inner wall of the card slot 15 opened on the outer wall of the L-shaped connecting block 14, the card block 11 will no longer be stressed. At this time, the spring 8 in the reset state will rebound and reset, thereby causing the card block 11 to reset and slide completely into the inner wall of the card slot 15, fixing the L-shaped connecting block 14, thereby completing the rapid installation of the sealing strip 13. The rapid installation of the sealing strip 13 further improves the sealing effect. When it is necessary to classify and store the products inside the packaging box body 1, first slide the first partition plate 16 on the inner wall of the packaging box body 1, and then slide the second partition plate 19 with the second partition plate 19. The inner wall of the first fixing groove 17 is opened on the outer wall of the first partition plate 16. During this process, the outer wall of the second partition plate 19 will also slide on the inner wall of the packaging box body 1, and then the third partition plate 20 will slide at the same time on the inner wall of the second fixing groove 18 starting from the inner wall of the packaging box body 1 and the outer wall of the first partition plate 16. After sliding to the limit, it is necessary to use the fixing block 21 to fix the first partition plate 16, the third partition plate 20 and the second fixing groove 18. At this time, it is only necessary to align the first rectangular groove 22 opened on the lower surface of the fixing block 21 with the outer wall of the first partition plate 16, and align the second rectangular groove 22 opened on the lower surface of the fixing block 21 with the outer wall of the first partition plate 16. Align the third partition plate 20 with the outer wall of the second fixing groove 18, and then move the fixing block 21 downward. During the downward movement, the second fixing groove 18 and the third partition plate 20 will slide within the inner wall of the second rectangular groove 23 opened on the lower surface of the fixing block 21. At the same time, the outer wall of the first partition plate 16 will slide within the inner wall of the first rectangular groove 22 opened on the lower surface of the fixing block 21, thereby fixing the first partition plate 16, the second fixing groove 18, and the third partition plate 20, thereby preventing them from moving or dislocating during transportation or handling, avoiding collision and friction between products, and ensuring that the appearance and function of the products are not damaged.
