Description

Technical Field

[0001] This utility model relates to the field of logistics turnover box technology, specifically a replaceable moisture-proof mat for logistics turnover boxes. Background Technology

[0002] In the field of modern logistics warehousing and transportation, logistics turnover boxes, as standardized loading containers, are widely used in the storage and transfer of various goods such as electronic products, food, textiles, and precision parts.

[0003] A search revealed a logistics turnover box published by Chinese Patent No. CN219545491U. The box effectively reduces external collisions caused by shaking or loading and unloading by fixing and reinforcing the anti-collision frame on the outer wall of the box. This is combined with multiple sets of anti-collision buffer pads and reinforced anti-collision pads inside the box.

[0004] The moisture-proof mats of existing logistics turnover boxes mostly adopt a one-piece molded structure, which usually contains desiccant, moisture-proof cotton and other moisture-proof media. The moisture-proof media are mostly fixedly packaged. Once they become saturated or ineffective, they cannot be replaced individually. The entire mat needs to be discarded and replaced, which not only increases logistics operating costs, but also wastes resources. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The existing technology mentioned above has the shortcomings and defects of using a one-piece molded structure for the moisture-proof mat, which cannot be replaced individually and requires the entire mat to be discarded and replaced, resulting in a waste of resources.

[0006] This utility model discloses a replaceable moisture-proof mat for logistics turnover boxes, including an outer shell with a cavity extending through it. Both ends of the outer shell are provided with cover plates, and a fixing component is provided between the cover plates and the outer shell. A moisture-proof board is installed on the side of the cover plate closest to the outer shell, and a connector is provided between the moisture-proof board and the cover plate. The moisture-proof board is disposed inside the cavity, and a top plate is installed on the side of the moisture-proof board away from the cover plate. The top plate has a through hole, and a placement groove is provided on the side of the moisture-proof board closest to the top plate.

[0007] Furthermore, a partition is provided inside the placement groove, the partition is fixedly connected to the placement groove, and the upper end of the partition abuts against the lower end face of the top plate.

[0008] Furthermore, two guide rails are installed on the side of the top plate near the moisture-proof board. The two guide rails are symmetrically installed at both ends of the top plate. A groove is provided on the moisture-proof board at the corresponding position of the guide rail, and the guide rail is slidably disposed with the groove.

[0009] Furthermore, the connector includes four fixing bolts, which are located at the four corners of the moisture-proof board. The moisture-proof board at the corresponding position of the fixing bolt has an installation hole, and the cover plate at the corresponding position of the installation hole has a threaded hole. One end of the fixing bolt passes through the installation hole and is threadedly connected to the threaded hole.

[0010] Furthermore, the cover plate has a groove on the side near the outer shell, the outer shell is inserted into the groove, and a sealing ring is installed on the outer ring of the moisture-proof board.

[0011] Furthermore, a positioning plate is fixedly installed on the bottom wall of the groove, and a positioning groove is provided on the moisture-proof plate at the corresponding position of the positioning plate. The positioning plate is inserted into the positioning groove, and the end of the positioning plate away from the groove is chamfered.

[0012] Furthermore, the fixing component includes an insert plate, a slot is provided on the cover plate at the corresponding position of the insert plate, the insert plate is inserted into the slot, a fixing rod is provided between the insert plate and the cover plate, a fixing hole is provided on the cover plate at the corresponding position of the fixing rod, a threaded hole is provided on the insert plate at the corresponding position of the fixing hole, and one end of the fixing rod passes through the fixing hole and is threadedly connected to the threaded hole.

[0013] Furthermore, a push-pull groove is provided at one end of the top plate, the groove is not through-hole, and a rubber pad is provided at the top of the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves convenient disassembly and assembly of the cover plate through the fixing components of the cover plate and the outer shell. With the connecting parts of the moisture-proof board and the cover plate, the two can be separated. Combined with the sliding structure of the guide rail groove of the top plate and the moisture-proof board, the moisture-proof medium placed in the groove can be easily removed. It realizes the individual disassembly and replacement of the moisture-proof board and the internal moisture-proof medium without discarding the entire pad. It effectively solves the problem that the existing one-piece molded moisture-proof pad needs to be replaced as a whole after the moisture-proof medium fails, reducing logistics and operating costs and reducing resource waste.

[0015] 2. The sealing ring on the outer ring of the moisture-proof board of this utility model enhances the sealing performance with the outer shell, improving the moisture-proof effect; the interlocking fit between the positioning plate and the positioning groove improves the assembly accuracy of the cover plate and the moisture-proof board, ensuring structural stability; the rubber pad at the top of the sliding groove can buffer and limit movement, preventing excessive sliding of the top plate, while the push-pull groove facilitates the pulling operation of the top plate. This ensures the stability and moisture-proof reliability of the mat during frequent loading and unloading in logistics turnover, making the replacement of the moisture-proof medium simple and efficient, and adapting to the actual needs of various cargo storage and transportation scenarios.

A waterproof gasket is provided between the fixing rod 20 and the fixing hole 22 to prevent external moisture from seeping in through the gap. A moisture-proof board 5 is installed on the side of the cover plate 3 near the outer shell 1. The moisture-proof board 5 is made of ABS engineering plastic.

[0022] See Figure 3 , Figure 4 As shown, a sealing ring 23 is installed on the outer ring of the moisture-proof board 5. The sealing ring 23 is made of food-grade silicone. A positioning plate 16 is fixedly installed on the inner bottom wall of the groove 4. There are two positioning plates 16, which are symmetrically distributed. A positioning groove 17 is provided on the moisture-proof board 5 at the corresponding position of the positioning plate 16. The positioning plate 16 is inserted into the positioning groove 17. The end of the positioning plate 16 away from the groove 4 is chamfered to facilitate quick alignment and insertion. A connector is provided between the moisture-proof board 5 and the cover plate 3. The connector includes a fixing bolt 13, and there are four fixing bolts 13.

[0023] See Figure 3 As shown, the fixing bolts 13 are stainless steel hexagon socket head cap screws. Four fixing bolts 13 are set at the four corners of the moisture-proof board 5. The moisture-proof board 5 at the corresponding position of the fixing bolts 13 is provided with mounting holes 15. The cover plate 3 at the corresponding position of the mounting holes 15 is provided with threaded holes 14. One end of the fixing bolt 13 passes through the mounting hole 15 and is threadedly connected to the threaded hole 14. The head of the fixing bolt 13 is embedded in the mounting hole 15.

[0024] See Figure 3 , Figure 5 As shown, the head end face of the fixing bolt 13 is flush with the surface of the moisture-proof plate 5 to avoid interfering with the sliding of the top plate 8. The moisture-proof plate 5 is set inside the cavity 2. The top plate 8 is installed on the side of the moisture-proof plate 5 away from the cover plate 3. The top plate 8 is made of transparent PC plastic, which makes it easy to observe the state of the moisture-proof medium in the placement groove 6. Two guide rails 9 are installed on the side of the top plate 8 near the moisture-proof plate 5. The guide rails 9 have a T-shaped structure.

[0025] See Figure 3 , Figure 5As shown, two guide rails 9 are symmetrically installed at both ends of the top plate 8. A sliding groove 10 is provided on the moisture-proof plate 5 at the corresponding position of the guide rail 9. The sliding groove 10 is a matching T-shaped groove. The guide rail 9 and the sliding groove 10 are slidably arranged. A push-pull groove 12 is provided at one end of the top plate 8. The sliding groove 10 is not through-hole. The movement of the guide rail 9 is restricted by the sliding groove 10 to prevent the top plate 8 from sliding excessively. A rubber pad is provided at the top of the sliding groove 10 to buffer and limit the movement and avoid collision damage.

[0026] See Figure 2 , Figure 3 As shown, the top plate 8 is provided with multiple through holes 11, which are evenly distributed. The moisture-proof board 5 is provided with a placement groove 6 on the side near the top plate 8. A partition 7 is provided inside the placement groove 6. The partition 7 is made of the same ABS material as the moisture-proof board 5. The partition 7 is distributed in a grid pattern. The partition 7 will separate and limit the moisture-proof medium to prevent it from accumulating and shifting during turnover. The partition 7 and the placement groove 6 are integrally formed and fixedly connected. The upper end of the partition 7 abuts against the lower end face of the top plate 8.

[0027] The implementation principle is as follows: During installation, first, lay the moisture-proof medium, such as desiccant or moisture-proof cotton, flat in the placement groove 6 of the moisture-proof board 5. Hold the top plate 8 and slowly push the guide rails 9 at both ends of the top plate 8 into the sliding groove 10 until the guide rails 9 move to the top of the sliding groove 10. At this time, the through hole 11 on the top plate 8 is connected to the placement groove 6, providing a channel for the moisture-proof medium to function. Then, align the moisture-proof board 5 with the groove 4 of the cover plate 3, so that the positioning plate 16 is inserted into the positioning groove 17. At this time, the mounting hole 15 is aligned with the threaded hole 14. Then, use four fixing bolts 13 to pass through the corresponding... Mounting hole 15 is threaded to threaded hole 14 to fix moisture-proof board 5 and cover plate 3; align the assembled cover plate 3 with the outer shell 1, insert plate 18 into slot 19, and move it into the groove 4 at the end of the outer shell 1. Then, use fixing rod 20 to pass through fixing hole 22 and thread it to threaded hole 21. Then, put the item into the outer shell 1. After that, install the other cover plate 3 in the same way. Moisture in the air inside the box will enter the placement slot 6 through the through hole 11 of top plate 8 and be absorbed by the internal moisture-proof medium to achieve moisture protection for the goods. When the moisture-proof medium becomes saturated or ineffective, it is not necessary to replace the entire pad; only the moisture-proof medium needs to be replaced. Loosen the fixing rod 20 and remove it from the fixing hole 22 and threaded hole 21. Then pull out the insert plate 18 to release the cover plate 3 from the outer shell 1. Hold the cover plate 3 and pull it outward to remove the combination of the cover plate 3 and the moisture-proof plate 5 from the cavity 2 of the outer shell 1. Loosen the four fixing bolts 13 to separate the moisture-proof plate 5 from the cover plate 3. Alternatively, directly pull out the top plate 8 along the guide rail 9 through the push-pull groove 12. Remove the ineffective moisture-proof medium from the placement groove 6 and reinstall a new moisture-proof medium. Repeat the process in reverse to reinstall.
