Description

A waterproof and moisture-proof corrugated cardboard box Technical Field

[0001] This utility model relates to the field of corrugated cardboard boxes, and more specifically, to a waterproof and moisture-proof corrugated cardboard box. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products, and their usage has always been the highest among all packaging products, including calcium-plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also beautify and promote goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to the environment and facilitate loading, unloading and transportation.

[0003] A search revealed that Chinese Patent Publication No. CN213503391U discloses "a durable, waterproof, and moisture-proof corrugated cardboard box, comprising a corrugated cardboard box body with a reinforcing plate glued to the bottom, two cardboard box lids on the top of the corrugated cardboard box body, a PVC waterproof layer glued to the outer wall of the corrugated cardboard box body and the outer walls of the two cardboard box lids, two support columns welded to the bottom of the reinforcing plate, and a common base welded to the bottom of the two support columns, with buffer springs fitted on both support columns, and mounting boxes glued to the top outer walls of the two cardboard box lids. This invention provides good support when heavy items are placed inside the corrugated cardboard box body, and the two buffer springs cushion the weight of the items, preventing the bottom of the corrugated cardboard box body from being deformed, thus improving its durability. Furthermore, the bottom of the corrugated cardboard box body does not contact the ground, making it less susceptible to moisture." However, it still has the following drawbacks:

[0004] (1) The above-mentioned corrugated cardboard boxes cannot be disassembled and replaced, and the sealing effect is also poor.

[0005] (2) When changing the desiccant, the installation box needs to be removed each time, the desiccant needs to be placed in it, and then it needs to be glued back on, which is quite cumbersome.

[0006] Therefore, we made improvements and proposed a waterproof and moisture-proof corrugated cardboard box. Summary of the Invention

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] As shown in Figures 1-5, this embodiment proposes a waterproof and moisture-proof corrugated cardboard box, including a base plate 1. A sealing mechanism 2 is installed on the top of the base plate 1. The sealing mechanism 2 includes a slide rod 201. A protective shell 202 and a sealing plate 204 are slidably connected to the outer wall of the slide rod 201 in sequence. A first locking rod 203 is fixedly connected to the bottom of the protective shell 202, and the end of the first locking rod 203 is snapped into the outer wall of the base plate 1. A second locking rod 205 is fixedly connected to the bottom of the sealing plate 204, and the second locking rod 205 is snapped into the top of the protective shell 202. A handle 207 is fixedly connected to the top of the sealing plate 204. A nut 206 is threadedly connected to the outer wall of the slide rod 201. The end of the slide rod 201 is fixedly connected to the top of the base plate 1. By pushing the protective shell 202 to move on the slide rod 201, the protective shell 202 also drives the first locking rod 203 to move. When the first locking rod 203 is inserted into the base plate 1, the handle 207 is then held to drive the sealing plate 204 to move. The sealing plate 204 moves on the slide rod 201 to drive the second locking rod 205 to move. When the second locking rod 205 is inserted into the protective shell 202, the nut 206 is rotated on the slide rod 201 to rotate and contact the sealing plate 204, thereby quickly installing the corrugated carton and improving the sealing performance of the corrugated carton.

[0035] As shown in Figures 3, 4, and 5, a waterproof and moisture-proof mechanism 3 is installed on one side of the protective shell 202. The waterproof and moisture-proof mechanism 3 includes a drying box 302. A third latch 304 is snapped onto the outer wall of the drying box 302. A sealing cover 303 is fixedly connected to one end of the third latch 304. A bolt 305 is threaded onto the outer wall of the sealing cover 303, with the end of the bolt 305 extending into the drying box 302. The top of the drying box 302 is fixedly connected to the bottom of the sealing plate 204. A layer of waterproof coating 301 is applied to the inner wall of the protective shell 202. The drying box 302 is then dried. The desiccant is placed into the desiccant box 302. Then, the sealing cover 303 is pushed to move. As the sealing cover 303 moves, the third latch 304 also moves. When the third latch 304 is engaged inside the desiccant box 302, the bolt 305 is rotated on the sealing cover 303 and enters the desiccant box 302 to seal the desiccant box 302. This also facilitates the replenishment of the desiccant to improve the moisture-proof performance of the corrugated cardboard box. The waterproof coating 301 applied to the inner wall of the protective shell 202 further enhances the waterproof performance of the corrugated cardboard box.

[0036] As shown in Figures 1 and 3, a first slot is provided at the bottom of the base plate 1 to match the first locking rod 203, and the end of the first locking rod 203 is inserted into the first slot to facilitate the first locking rod 203 to be inserted into the base plate 1.

[0037] As shown in Figure 3, a second slot is provided on the top of the protective shell 202 to match the second locking rod 205, and the end of the second locking rod 205 is inserted into the second slot to facilitate the second locking rod 205 being inserted into the protective shell 202.

[0038] As shown in Figures 3 and 4, the inner walls of the protective shell 202 and the sealing plate 204 are provided with through holes that are compatible with the slide rod 201, so that the protective shell 202 and the sealing plate 204 can move on the slide rod 201.

[0039] As shown in Figure 5, the inner walls of the drying box 302 and the sealing cover 303 are provided with threaded grooves that are compatible with the bolt 305, so that the bolt 305 can rotate on the sealing cover 303 and enter into the drying box 302 to fix the sealing cover 303.

[0040] As shown in Figure 5, a third slot is provided on the outer wall of the drying box 302 to match the third locking rod 304, and one end of the third locking rod 304 is inserted into the third slot to facilitate the third locking rod 304 being inserted into the drying box 302.

[0041] Specifically, when using this type of waterproof and moisture-proof corrugated cardboard box: by pushing the protective shell 202 to move on the slide rod 201, the movement of the protective shell 202 also moves the first locking rod 203. When the first locking rod 203 is engaged in the bottom plate 1, then the handle 207 is grasped to move the sealing plate 204. The sealing plate 204, by moving on the slide rod 201, moves the second locking rod 205. When the second locking rod 205 is engaged inside the protective shell 202, then the nut 206 is rotated on the slide rod 201 to rotate and contact the sealing plate 204, thereby quickly assembling the corrugated cardboard box. This also improves the sealing performance of the corrugated cardboard box. By placing the desiccant into the desiccant box 302, the sealing cover 303 is pushed to move. As the sealing cover 303 moves, the third latch 304 also moves. When the third latch 304 is engaged inside the desiccant box 302, the bolt 305 is rotated on the sealing cover 303 and enters the desiccant box 302 to seal the desiccant box 302. This also facilitates the replenishment of the desiccant, thereby improving the moisture-proof performance of the corrugated cardboard box. The waterproof coating 301 applied to the inner wall of the protective shell 202 further enhances the waterproof performance of the corrugated cardboard box.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
