The right side plate 3 and the right connecting plate 5 are sequentially connected to the right side of the base plate 1. Right fixing plates 7 are connected to both sides of the right connecting plate 5. The two right fixing plates 7 are folded towards each other and interlocked. An assembly space is formed between the folded right fixing plates 7 and the right connecting plate 5. Ventilation holes are provided on both the left fixing plates 6 and the right fixing plates 7. The drying component is disposed within the assembly space. As can be seen from the above description, the beneficial effects of this utility model are as follows: by folding the cardboard components set on both sides of the base plate 1, assembly spaces can be formed on both sides of the box. Ventilation holes are opened in the assembly space and drying components are arranged therein, which can keep the inside of the box dry and meet the storage needs of specific items. When folding, the left side plate 2 and the left connecting plate 4 on the left side of the base plate 1 are folded in sequence to form a structure perpendicular to the base plate 1. Then, the left fixing plates 6 on both sides of the left connecting plate 4 are folded towards the base plate 1 and interlocked with each other, forming an assembly space between the left connecting plate 4 and the left fixing plate 6. Then, a conventional drying component can be placed in it. Similarly, an assembly space composed of the right connecting plate 5 and the right fixing plate 7 is formed on the left side of the base plate 1 and a drying component is arranged therein. Furthermore, the left fixing plate 6 includes a first connecting plate 61, a second connecting plate 62, and a third connecting plate 63. The first connecting plate 61, the second connecting plate 62, and the third connecting plate 63 are sequentially connected to both sides of the left connecting plate 4. The third connecting plate 63 has a first insert plate 631 on the side away from the second connecting plate 62. The left connecting plate 4 has a first insertion hole 41 corresponding to the two first insert plates 631. As described above, after the left side plate 2 and the left connecting plate 4 are folded to form the vertical structure on the left side of the base plate 1, the left fixing plate 6 on one side is folded toward the left fixing plate 6 on the other side. That is, the first connecting plate 61, the second connecting plate 62 and the third connecting plate 63 are folded in sequence. The folded first connecting plate 61 and the third connecting plate 63 are perpendicular to the left connecting plate 4. The first insert plate 631 on the third connecting plate 63 is inserted and fixed to the first insert hole 41 on the left connecting plate 4, while the second connecting plate 62 is parallel to the left connecting plate 4. The first connecting plate 61, the second connecting plate 62, the third connecting plate 63 and the left connecting plate 4 cooperate to form an assembly space. Furthermore, the right fixing plate 7 includes a fourth connecting plate 71, a fifth connecting plate 72, and a sixth connecting plate 73. The right connecting plate 5 has the fourth connecting plate 71, the fifth connecting plate 72, and the sixth connecting plate 73 connected sequentially on both sides. The sixth connecting plate 73 has a second insert plate 731 on the side away from the fifth connecting plate 72. The right connecting plate 5 has a second insertion hole 51 corresponding to the two second insert plates 731.As described above, after the right side plate 3 and the right connecting plate 5 are folded to form the vertical structure on the right side of the base plate 1, the right fixing plate 7 on one side is folded towards the right fixing plate 7 on the other side, that is, the fourth connecting plate 71, the fifth connecting plate 72, and the sixth connecting plate 73 are folded in sequence. The folded fourth connecting plate 71 and the sixth connecting plate 73 are perpendicular to the right connecting plate 5. The second insert plate 731 on the sixth connecting plate 73 is inserted and fixed to the second insert hole 51 on the right connecting plate 5, while the fifth connecting plate 72 is parallel to the right connecting plate 5. The fourth connecting plate 71, the fifth connecting plate 72, the sixth connecting plate 73, and the right connecting plate 5 cooperate to form an assembly space. Further, the two third connecting plates 63 on both sides of the left connecting plate 4 abut against each other after folding. As described above, the two third connecting plates 63 abut against each other after folding through size control, forming a mutual limiting and fixing. Further, the two sixth connecting plates 73 on both sides of the right connecting plate 5 abut against each other after folding. As described above, by controlling the dimensions, the two folded sixth connecting plates 73 abut against each other, forming a mutually limiting and fixed structure. Further, the second connecting plate 62 has a first top plate 8 near the bottom plate 1, and first flaps 9 on both sides of the first top plate 8; the first top plate 8 folds down to close the upper end of the assembly space between the left fixing plate 6 and the left connecting plate 4, and the two first flaps 9 are inserted into this assembly space. As described above, through the design of the first top plate 8 and the first flaps 9 on both sides, it can form a structure for opening and closing the upper end of the assembly space after the assembly space is formed; after the drying component is installed, it can be closed to prevent the drying component from falling out during shaking. Further, the fifth connecting plate 72 has a second top plate 10 near the bottom plate 1, and second flaps 11 on both sides of the second top plate 10; the second top plate 10 folds down to close the upper end of the assembly space between the right fixing plate 7 and the right connecting plate 5, and the two second flaps 11 are inserted into this assembly space. As described above, the design of the second top plate 10 and the second flaps 11 on both sides allows for the formation of an opening and closing structure at the upper end of the assembly space after the assembly space is formed. After the drying component is installed, it can be sealed to prevent the drying component from coming out during shaking. Furthermore, it also includes a first movable plate 12, with the second connecting plate 62 recessed in the middle on the side away from the bottom plate 1. One end of the first movable plate 12 is connected to the recessed middle portion of the second connecting plate 62, and the other end extends in a direction away from the bottom plate 1. The middle portion of the first movable plate 12 has a crease parallel to the edge of the second connecting plate 62 on the side away from the bottom plate 1. After folding, one end of the first movable plate 12 is located between the left fixed plate 6 and the left connecting plate 4, forming the lower end of the assembly space, and the drying component abuts against the first movable plate 12.As described above, the first movable plate 12 serves as the structure on the side of the second connecting plate 62 away from the base plate 1. After folding, it is located on the lower side of the corresponding assembly space. The crease design of the first movable plate 12 allows it to be folded so that one end can extend into the assembly space. After the drying component is placed into the assembly space, the lower end of the drying component can abut against the end of the first movable plate 12. When it is necessary to remove the drying component, the operator can lift the first movable plate 12 to push the drying component inside the assembly space out. At the same time, the concave design of the middle part of one side of the second connecting plate 62 makes the first movable plate 12 form a hollow structure on the second connecting plate 62 after folding, which can be used as a ventilation hole. Furthermore, it also includes a second movable plate 13. The fifth connecting plate 72 has a recessed center on the side away from the bottom plate 1. One end of the second movable plate 13 is connected to the recessed center on one side of the fifth connecting plate 72, and the other end extends in the direction away from the bottom plate 1. The second movable plate 13 has a crease in the middle that is parallel to the edge of the fifth connecting plate 72 on the side away from the bottom plate 1. After the second movable plate 13 is folded, one end of it is located between the right fixed plate 7 and the right connecting plate 5 to form the lower end of the assembly space. The drying component abuts against the second movable plate 13. As described above, the second movable plate 13, as the structure on the side of the fifth connecting plate 72 away from the base plate 1, is located on the lower side of the corresponding assembly space after folding. The crease design of the second movable plate 13 allows it to be folded so that one end can extend into the assembly space. After the drying component is placed into the assembly space, the lower end of the drying component can abut against the end of the second movable plate 13. When it is necessary to remove the drying component, the operator can lift the second movable plate 13 to push the drying component inside the assembly space out. At the same time, the concave design of the middle part of one side of the fifth connecting plate 72 makes the second movable plate 13 form a hollow structure on the fifth connecting plate 72 after folding, which can be used as a ventilation hole. Furthermore, it also includes a front side panel 14, a rear side panel 15, and a cover plate 16. The front side panel 14 is connected to the front side of the bottom plate 1. The front side panel 14 has third insert plates 17 on both sides. The two third insert plates 17 are respectively inserted between the left connecting plate 4 and the left fixing plate 6, and between the right connecting plate 5 and the right fixing plate 7. The rear side of the bottom plate 1 is connected to the rear side of the bottom plate 1 in sequence with the rear side panel 15. The rear side panel 15 has fourth insert plates 18 on both sides. The two fourth insert plates 18 are respectively inserted between the left connecting plate 4 and the left fixing plate 6, and between the right connecting plate 5 and the right fixing plate 7. As can be seen from the above description, a complete box body is formed by folding the bottom plate 1, the left side panel 2, the right side panel 3, the left connecting plate 4, the right connecting plate 5, the front side panel 14, the rear side panel 15, and the cover plate 16. The front side panel 14 is fixed to the structure on both sides of the bottom plate 1 by the third insert plates 17, and the rear side panel 15 is fixed to the structure on both sides of the bottom plate 1 by the fourth insert plates 18. Example 1: A corrugated cardboard box with moisture-proof function. The cardboard box is designed with a folding structure to form a space with built-in drying components on both sides of the box body, thereby achieving the purpose of continuous moisture protection.The carton is mainly made of a single piece of corrugated cardboard, which is die-cut, crimped, and then folded. On the left side of the base plate 1, a left side plate 2 and a left connecting plate 4 are connected in sequence; on the right side of the base plate 1, a right side plate 3 and a right connecting plate 5 are connected in sequence. When the left side plate 2 and left connecting plate 4, and the right side plate 3 and right connecting plate 5 are folded upwards, they form the basic left and right side walls of the carton. On both sides of the left connecting plate 4, a left fixing plate 6 is connected. Each left fixing plate 6 is further composed of a first connecting plate 61, a second connecting plate 62, and a third connecting plate 63 connected in sequence, with a first insert plate 631 at the end of the third connecting plate 63, and a corresponding first insertion hole 41 on the left connecting plate 4. During assembly, the two left fixing plates 6 are folded towards each other: first, the first connecting plate 61 is folded inward so that it is perpendicular to the left connecting plate 4; then, the second connecting plate 62 is folded inward parallel to the left connecting plate 4; finally, the third connecting plate 63 is folded inward again so that it is perpendicular to the left connecting plate 4, and the two third connecting plates 63 abut against each other. At the same time, the first insert plate 631 at the end of the third connecting plate 63 is inserted into the first insertion hole 41 on the left connecting plate 4 to complete the fixation. After this series of folds, a three-sided closed assembly space with openings at the top and bottom is formed between the left fixing plate 6 and the left connecting plate 4. The structure on the right side is symmetrical to the left side and operates on the same principle. The right connecting plate 5 is connected to the right fixing plates 7 on both sides. Each right fixing plate 7 includes a fourth connecting plate 71, a fifth connecting plate 72, and a sixth connecting plate 73. The sixth connecting plate 73 is provided with a second insert plate 731, and the right connecting plate 5 has a second insertion hole 51. Through the same folding and insertion method, the same assembly space is also formed on the right side. Ventilation holes are provided on both the second connecting plate 62 and the fifth connecting plate 72. To accommodate and secure drying components, such as silica gel desiccant packets, the carton features a specialized sealing and support structure. A first top plate 8 is connected to the second connecting plate 62 of the left fixing plate 6 near the bottom plate 1, and first flaps 9 are connected to both sides of the first top plate 8. Once the assembly space on the left is formed, folding the first top plate 8 downwards closes the upper opening of the assembly space, and the first flaps 9 on both sides are inserted into the space for enhanced fixation. The right side structure is similar; the upper end of the right assembly space is closed by the second top plate 10 on the fifth connecting plate 72 and the second flaps 11 on both sides, effectively preventing the drying components from falling off during transportation. To facilitate the placement and removal of the drying components and provide bottom ventilation, a first movable plate 12 is provided on the side of the second connecting plate 62 away from the bottom plate 1. One end of the first movable plate 12 is connected to a recessed position in the middle of the second connecting plate 62, and a crease is provided in the middle of the plate. When the first movable plate 12 is folded at a specific angle along the crease, one end extends into the bottom of the left assembly space, forming a structure that supports the drying components. When the drying component needs to be replaced, simply push the first movable plate 12 upwards from the outside to push the old drying component out from the top of the assembly space; the operation is extremely simple.Meanwhile, the gap left on the second connecting plate 62 after the first movable plate 12 is folded naturally forms a ventilation hole, facilitating contact between moisture inside the box and the drying components. The fifth connecting plate 72 on the right side also has a second movable plate 13 with the exact same structure and function. A front side plate 14 is connected to the front of the base plate 1, and third insert plates 17 are provided on both sides of the front side plate 14. During assembly, these two third insert plates 17 are respectively inserted between the left connecting plate 4 and the left side plate 2, and between the right connecting plate 5 and the right side plate 3. On the rear side of the base plate 1, a rear side plate 15 and a cover plate 16 are connected in sequence. The fourth insert plates 18 on both sides of the rear side plate 15 are also inserted between the left connecting plate 4 and the left side plate 2, and between the right connecting plate 5 and the right side plate 3 for fixation. The cover plate 16 can be folded over to cover the entire top of the box.

[0018] In summary, the corrugated cardboard box with moisture-proof function provided by this utility model can form an assembly space on both sides of the box body by folding and forming the cardboard components set on both sides of the bottom plate. The assembly space is provided with ventilation holes and drying components to keep the inside of the box dry and meet the storage needs of specific items.
