Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Please refer to Figures 1 to 6 , a packaging carton with moisture-proof effect, including a box body 1 and a cover body 6. The cover body 6 can be simply and quickly covered on the box body 1, so that the box body 1 and the cover body 6 form a closed space, which is convenient for placing items.

[0030] Two fixing bars 4 are fixedly installed inside the box body 1. An installation plate 7 is slidably installed between the two fixing bars 4. A partition plate 5 is fixedly installed at the bottom of the installation plate 7. Preferably, in order to protect the placed items, both sides of the partition plate 5 in direct contact with the items can be made of flexible materials;

[0031] By moving the installation plate 7 on the fixing bars 4, the distance between adjacent partition plates 5 can be adjusted, so that the size of the space for loading items between adjacent partition plates 5 can be adjusted according to actual needs, which is suitable for different usage requirements.

[0032] Springs 13 are fixedly installed on both sides of the installation plate 7. The other ends of the springs 13 are fixedly installed with pulling bars 8. A connecting rod 14 is fixedly installed on the pulling bar 8. The other end of the connecting rod 14 is fixedly installed with a tooth block 12.

[0033] By moving the pulling bar 8, the connecting rod 14 and the tooth block 12 thereon move synchronously, and the movement of the pulling bar 8 can compress the spring 13.

[0034] A rack 17 meshing with the tooth block 12 is fixedly installed inside the fixing bar 4.

[0035] When no external force is applied, under the action of the spring 13, the tooth block 12 is in the initial position. At this time, the tooth block 12 is in contact with the rack 17, and thus the tooth block 12 cannot move, so that the distance between adjacent partition plates 5 remains stable, which is convenient for protecting items.

[0036] When the distance between adjacent partition plates 5 needs to be adjusted, by making the two pulling bars 8 on one installation plate 7 approach each other, at this time the tooth block 12 is separated from the rack 17, and thus the rack 17 does not affect the movement of the tooth block 12, so that the installation plate 7 can move smoothly.

[0037] Sliders 9 are fixedly installed at both ends of the installation plate 7. Sliding grooves 18 for the sliders 9 to slide are provided on the fixing bars 4.

[0038] When the installation plate 7 moves on the fixing bars 4, the sliders 9 move synchronously on the sliding grooves 18, so that the installation plate 7 can move stably in one direction, ensuring the stability of the movement of the installation plate 7.

[0039] Both of the two fixing bars 4 are provided with placing slots 16 into which the mounting plate 7 can be placed. The placing slots 16 are located at the edge of one side of the fixing bar 4.

[0040] Through the placing slots 16, the mounting plate 7 and the partition plate 5 thereon can be smoothly placed into the box body 1, so that the number of spaces for placing items can be adjusted according to actual needs, making the device applicable to different usage scenarios.

[0041] The partition plate 5 is provided with a placing cavity 10, and a shielding plate 11 that can close the placing cavity 10 is slidably mounted at the corresponding position of the partition plate 5. The placing cavity 10 is used to place a moisture-proof agent, and the shielding plate 11 can shield the placing cavity 10 to prevent the moisture-proof agent from accidentally falling. Preferably, the shielding plate 11 should be made of a breathable and porous material to ensure the moisture-proof effect, and the placing density of the moisture-proof agent should be independently adjusted according to the actual usage scenario.

[0042] A connecting block 15 is fixedly mounted on the shielding plate 11, and the connecting block 15 is fixedly connected to the pulling bar 8.

[0043] When the pulling bar 8 is moved, the shielding plate 11 will move synchronously under the driving action of the connecting block 15, and then the placing cavity 10 can be expanded, so that the moisture-proof agent can be smoothly placed and taken out.

[0044] A support pad 2 is fixedly mounted at the bottom of the box body 1, and a reinforcing rib 19 is fixedly mounted inside the support pad 2. The reinforcing rib 19 is a rod-shaped structure with a crisscross pattern.

[0045] The existence of the support pad 2 can prevent the box body 1 from directly contacting the ground, which can play a moisture-proof role to a certain extent. The existence of the crisscross reinforcing ribs 19 can enhance the stiffness of the box body 1 to a certain extent, so that the box body 1 can be reused.

[0046] Compression bars 20 are fixedly mounted at the four corners of the box body 1. The compression bars 20 are located inside the box body 1. The compression bars 20 can resist the force in the vertical direction, thus ensuring the compressive ability and also improving the service life of the box body 1.

[0047] A sealing ring 3 is fixedly mounted on the side of the box body 1 facing the cover body 6. The sealing ring 3 is adapted to the cover body 6. When the cover body 6 is smoothly combined with the box body 1, the sealing ring 3 is in interference fit with the gap between the cover body 6 and the cover body 6, so as to prevent moisture from invading from the gap and play a moisture-proof role.

[0048] The working process of the present utility model is as follows: First, according to actual needs, a specified number of mounting plates 7 and the partition plates 5 thereon are smoothly placed into the box body 1 through the placing slot 16, and then the distance between adjacent mounting plates 7 is adjusted.

[0049] By making the two pulling bars 8 on one mounting plate 7 approach each other, at this time, the tooth block 12 is separated from the rack 17, and further, the rack 17 will not affect the movement of the tooth block 12, enabling the mounting plate 7 to move smoothly. When reaching the required position, the applied force is cancelled, and under the action of the spring 13, the tooth block 12 fits with the rack 17, and further, the tooth block 12 cannot move, so that the distance between adjacent partition plates 5 is kept stable, facilitating the protection of items.

[0050] When the pulling bar 8 is moved, through the driving action of the connecting block 15, the shielding plate 11 will move synchronously, and further, the placing cavity 10 can be unfolded, so that the moisture-proof agent can be smoothly placed and taken out. The placing density of the moisture-proof agent should be independently adjusted according to the actual use scenario.

[0051] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
