[0023] Example
[0024] Please refer to the following: Figure 1-6 This utility model discloses an EPS foam insulation box with a locking mechanism, comprising a box body 1 and a box lid 2. The box body 1 includes a first A side panel 101, a first B side panel 102, two second side panels 103, and a bottom plate 104. A partition 3 is detachably installed inside the box body 1. A short slot 4 is formed in the middle of the inner wall of the first A side panel 101, and long slots 5 are formed on both sides of the inner wall of the first A side panel 101. A long slot 5 is formed in the middle of the first B side panel 102, and short slots 4 are formed on both sides of the first B side panel 102. Each short slot 4 and long slot 5 are connected to the long slot 5. The length and width of the slot 5 are consistent. A first locking block 6 is fixedly connected to the middle of one side of the partition 3. Two locking blocks 7 are fixedly connected to both ends of the side of the partition 3 away from the first locking block 6. The first locking block 6 and the second locking block 7 correspond to the positions of each short slot 4 or long slot 5. A first permeable mesh plate 17 is provided on the partition 3. A water storage tank 18 is opened in the partition 3. The first permeable mesh plate 17 is detachably connected to the partition 3. A second permeable mesh plate 19 is provided on the bottom plate 104. The second permeable mesh plate 19 is detachably connected to the bottom plate 104.
[0025] Among them, the two second side plates 103 are provided with limiting slots 15 on the opposite side. The bottom two sides of the box cover 2 are fixedly connected to limiting plates 8. Each limiting plate 8 is slidably connected to the corresponding limiting slot 15. The limiting plate 8 slides into the corresponding limiting slot 15 and the box cover 2 fits into the box body 1. The top two sides of the box cover 2 are provided with first through holes 9. The top two sides of the two second side plates 103 are provided with second through holes 16. The top two sides of the two limiting plates 8 are provided with limiting holes 10. The top two sides of the box cover 2 are provided with cover plates 11. The bottom two sides of each cover plate 11 are fixedly connected to limiting rods 12. Each limiting rod 12 passes through the corresponding first through hole 9 and second through hole 16 and is inserted into the corresponding limiting hole 10. The top middle of each cover plate 11 is provided with a lifting handle 14. The lifting handle 14 is fixedly connected to the cover plate 11. The bottom two sides of each cover plate 11 are provided with disposable adhesive film 13.
[0026] Specifically, when using this utility model, depending on the placement requirements, the first locking block 6 on the partition 3 is positioned facing either the first A side plate 101 or the first B side plate 102. With the first locking block 6 facing the first A side plate 101, the first locking block 6 and each of the second locking blocks 7 slide into the short slots 4 on the first A side plate 101 and the first B side plate 102, respectively. This increases the gap between the partition 3 and the bottom plate 104, improving the placement space below the partition 3. Conversely, when the first locking block 6 faces the first B side plate, the first locking block 6 and each of the second locking blocks 7 slide into the long slots 5 on the first A side plate 101 and the first B side plate 102, respectively, increasing the placement space above the partition 3. Simultaneously, the partition 3 effectively separates the goods, preventing damage caused by stacking.
[0027] After the goods are placed, slide the limiting plate 8 on the lid 2 into the corresponding limiting slot 15 on the body 1. At this time, the lid 2 is attached to the body 1. Then, cover the top two sides of the lid 2 with the cover plate 11, so that the corresponding limiting rod 12 passes through the corresponding first through hole 9 and second through hole 16 and is inserted into the corresponding limiting hole 10. The rod 12 limits and fixes the lid 2 to prevent it from sliding. At the same time, the disposable adhesive film 13 is used to stick the cover plate 11 to the lid 2 to prevent the cover plate 11 from being dislodged by vibration and causing the lid 2 to slide open. The operator can lift the cover plate 11 upward by holding the lifting handle 14. Without external force, the disposable adhesive film 13 can ensure the stability of the adhesion between the cover plate 11 and the lid 2.
[0028] During cargo transportation, the No. 1 permeable mesh plate 17 can effectively allow the water droplets generated by condensation or temperature rise on the goods on the partition 3 to flow into the water storage tank 18, and the No. 2 permeable mesh plate 19 can effectively allow the water droplets generated by condensation or temperature rise on the goods on the bottom plate 104 to flow out of the box 1, effectively preventing the goods from being soaked in water.
[0029] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
