Description

Technical Field

[0001] This utility model relates to the field of transshipment box technology, and more specifically, it relates to a moisture-proof device for port logistics parks. Background Technology

[0002] Transfer containers, also known as logistics boxes, are widely used in various industries such as machinery, automotive, home appliances, light industry, and electronics. These containers are acid and alkali resistant, oil-resistant, non-toxic, and odorless; they can even be used for food storage and are easy to clean and maintain. Transfer containers are commonly used in transportation, distribution, warehousing, and processing in factory logistics, and can be used with various logistics containers and workstation equipment, finding wide application in various warehouses and production sites. As logistics management gains increasing importance for businesses, transfer containers have become a key tool for promoting the standardization and integrated management of logistics containers, and an important component of efficient logistics operations for modern production and distribution enterprises.

[0003] The existing transit containers used in logistics still have the following problems: While existing transit boxes are equipped with lids, they generally lack the ability to dry the sealed air inside. In humid environments or during prolonged sealed storage, moisture cannot be effectively expelled, easily leading to dampness, mold, oxidation, or damage to the contents. This poses a significant quality risk, especially for materials sensitive to humidity, such as electronic components and precision parts. Furthermore, most transit box lids currently use traditional fixing methods like bolts, making opening and closing cumbersome and time-consuming. In fast-paced logistics operations, the inability to quickly open, close, and seal the boxes directly impacts handling and storage efficiency, increases labor costs and time consumption, and fails to meet the demands of modern, efficient logistics.

[0004] In view of this, we propose a moisture-proof device for port logistics parks. Utility Model Content

[0022] Please see Figures 1-5 A moisture-proof device for port logistics parks includes a box body 1. A sealing cover 2 is installed on the upper part of the box body 1. A through hole 11 is provided in the middle of the sealing cover 2. A threaded pipe 3 is fixedly connected to the through hole 11 of the sealing cover 2. A threaded sleeve 4 is threadedly connected to the threaded pipe 3. A holding shell 5 is fixedly connected to the middle of the threaded sleeve 4. A support net 6 is detachably fixed to the lower part of the holding shell 5. A desiccant is placed inside the holding shell 5. Handles 7 are fixedly connected to both sides of the sealing cover 2. Two limiting posts 8 are fixedly connected to the box body 1. The limiting posts 8 penetrate the sealing cover 2. Limiting sleeves 9 are fitted on the limiting posts 8. The sleeve 9 is fixedly connected to the extrusion plate 10, which is fixedly connected to the sealing cover 2. The limiting sleeve 9 is provided with circumferentially evenly distributed through holes 11, and steel balls 12 are provided in the through holes 11. The limiting sleeve 9 is provided with a limiting structure. The limiting post 8 is provided with an annular groove 13, and the steel balls 12 are in a limiting fit with each other. The limiting sleeve 9 is slidably connected to the sliding sleeve 14, and the inner wall of the sliding sleeve 14 is provided with an extrusion part, which is in an extrusion fit with the steel balls 12. The outer side of the limiting sleeve 9 is fitted with a spring 15, and the two ends of the spring 15 are fixedly connected to the limiting sleeve 9 and the sliding sleeve 14 respectively.

[0023] Please see Figure 4 and Figure 5 The limiting structure includes a support frame 16, which is fixedly connected to the limiting sleeve 9. The support frame 16 is slidably connected to a limiting rod 17, which passes through the limiting sleeve 9. The support frame 16 is provided with a blind hole, in which a second spring 18 and a pressing column 19 are provided. The second spring 18 and the pressing column 19 are fixedly connected. The limiting rod 17 is fixedly connected to a limiting block 20. The limiting column 8 is provided with a limiting hole 21, which is in a limiting fit with the limiting rod 17. The lower part of the limiting block 20 is provided with two inclined surfaces, which are in a pressing fit with the pressing column 19.

[0024] The working principle of this utility model: Place the item inside the box 1, then place the sealing cover 2 on the box 1. Then, insert the inner post through the sealing cover 2 and into the adjacent limiting sleeve 9. Then, pull the sliding sleeve 14 upward. The squeezing part of the sliding sleeve 14 no longer squeezes the steel ball 12, and the spring 15 is compressed. Then, the limiting post 8 passes through the limiting sleeve 9. Then, release the sliding sleeve 14. Under the elastic force of the spring 15, the squeezing part of the sliding sleeve 14 squeezes the steel ball 12 again. The steel ball 12 is stuck in the annular groove 13. Thus, by using the cooperation of the steel ball 12 and the annular groove 13, the limiting post 8 and the limiting sleeve 9 are connected, thereby connecting the box 1 and the sealing cover 2.

[0025] Then push the limiting rod 17, which drives the limiting block 20 to move. The inclined surface of the limiting block 20 presses the extrusion column 19, which presses the spring 18 downward. The spring 18 is compressed, and the limiting rod 17 is inserted into the limiting hole 21. When the limiting block 20 moves to the left side of the extrusion column 19, the extrusion column 19 resets under the elastic force of the spring 18 and limits the right side of the limiting block 20.

[0026] The desiccant inside the housing 5 dries the air inside the box 1, preventing the items inside from getting damp and damaged. When the desiccant needs to be replaced, rotate the threaded sleeve 4 to remove the threaded sleeve 4 and the housing 5 from the sealing cover 2, and remove the support mesh 6 to replace the desiccant. When disassembly is required, first reset the limit rod 17, then pull the sliding sleeve 14 upwards with both hands. The sliding sleeve 14 moves upwards, and the steel ball 12 moves from the annular groove 13. Then, remove the limit sleeve 9 from the limit post 8, and then remove the sealing cover 2 from the box 1.

[0027] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
