[0024] Preferably: The dehumidifying mechanism includes: a partition 14, a connecting block 15, a baffle 16, a second bolt 17, a second fixing hole 18 and a through hole 19. A partition 14 is connected to the inner side surface of the box body 1, a connecting block 15 is connected to one end surface at the top of the partition 14, a baffle 16 is connected to the top surface of the connecting block 15, a second bolt 17 passes through the top surface of the baffle 16, and one end of the second bolt 17 extends into a second fixing hole 18 opened on the top surface of the connecting block 15, and a through hole 19 is opened on one end surface of the partition 14.

[0025] During specific use, place the drying packet between the partition 14 and the box body 1, place the baffle 16 on the top of the connecting block 15, at this time, pass the second bolt 17 through the baffle 16 and screw it into the second fixing hole 18, at this time, the position of the baffle 16 will be fixed on the connecting block 15, so that the position of the drying packet is restricted within the space formed between the partition 14 and the box body 1, in this way, the drying packet will adsorb the moisture in the air inside the box body 1 through the through hole 19.

[0026] Preferably: The placement block 6 is slidably connected to the box body 1 through the placement groove 5.

[0027] During specific use, the placement block 6 can be slidably placed into the placement groove 5 on the box body 1.

[0028] Preferably: The first sealing ring 7 forms a snap-fit structure with the box cover 3 through the first card slot 8, and the second sealing ring 9 forms a snap-fit structure with the box body 1 through the second card slot 10.

[0029] During specific use, slide the placement block 6 into the placement groove 5, which will drive the second sealing ring 9 to move to the position of the second clamping groove 10, causing the second sealing ring 9 to be clamped in the second clamping groove 10, thereby increasing the sealing performance between the placement block 6 and the box body 1. When the box cover 3 is closed on the box body 1, the first sealing ring 7 will be clamped in the first clamping groove 8, thereby increasing the sealing performance between the placement block 6 and the box cover 3.

[0030] Preferably: The first bolt 12 is slidably connected to the placement block 6 through the groove 11, and the first bolt 12 is threadedly connected to the first fixing hole 13 by passing through the placement block 6.

[0031] During specific use, pass the first bolt 12 through the placement block 6 and screw it into the first fixing hole 13, then the position of the placement block 6 can be fixed in the placement groove 5.

[0032] Preferably: The second bolt 17 is threadedly connected to the second fixing hole 18 by passing through the baffle 16.

[0033] During specific use, pass the second bolt 17 through the baffle 16 and screw it into the second fixing hole 18, then the position of the baffle 16 can be fixed on the connecting block 15.

[0034] Working principle of implementation: When using the sealing structure of this ammunition packing box, sliding the placement block 6 into the placement groove 5 will drive the second sealing ring 9 to move to the position of the second clamping groove 10, causing the second sealing ring 9 to be clamped in the second clamping groove 10, thereby increasing the sealing performance between the placement block 6 and the box body 1. At this time, place the first bolt 12 into the groove 11, and make the first bolt 12 pass through the placement block 6 and be screwed into the first fixing hole 13, then the position of the placement block 6 can be fixed in the placement groove 5. When the box cover 3 is closed on the box body 1, the first sealing ring 7 will be clamped in the first clamping groove 8, thereby increasing the sealing performance between the placement block 6 and the box cover 3. When the box cover 3 is closed on the box body 1, a sealing structure is formed between the two groups. Moreover, two groups of the first sealing ring 7 and the second sealing ring 9 are provided, thus forming a double-layer sealing structure, making the sealing effects of the first sealing ring 7 and the second sealing ring 9 better and the service life longer. When the first sealing ring 7 and the second sealing ring 9 are severely aged and unable to be used continuously, just turn the first bolt 12 to separate one end of the first bolt 12 from the first fixing hole 13, then the placement block 6 can slide out of the placement groove 5, enabling the aged first sealing ring 7 and second sealing ring 9 to be disassembled, allowing the operator to replace the placement block 6 with new first sealing ring 7 and second sealing ring 9 and install it into the placement groove 5 again, so that the ammunition packing box can be used again, avoiding the operator from replacing the whole ammunition packing box for use, thereby reducing the maintenance cost of the ammunition packing box. Secondly, place the drying packet between the partition 14 and the box body 1, and place the baffle 16 on the top of the connecting block 15. At this time, pass the second bolt 17 through the baffle 16 and screw it into the second fixing hole 18. At this time, the position of the baffle 16 will be fixed on the connecting block 15, restricting the position of the drying packet within the space formed between the partition 14 and the box body 1. In this way, when the box cover 3 is closed on the box body 1, the moisture contained in the air entering the interior of the box body 1 will be adsorbed by the drying packet through the through hole 19, ensuring the dryness of the air inside the box body 1 after the box cover 3 is closed and preventing the moisture from affecting the ammunition stored inside the box body 1.
