Example Embodiment
[0018] Example 1
[0019] Such as Figure 1-3 As shown, a fresh logistics transportation box includes a box body 1, a plurality of vent holes 2 are provided on the side wall of the box body 1, a cylindrical shell 3 is fixedly connected to the box body 1, and the box body 1 and the cylindrical shape One end of the shell 3 is provided with a cover plate that is sealed and connected. It should be noted that a plurality of vent holes 2 are evenly distributed on the side wall of the box 1 around the cylindrical shell 3, and the cylindrical shell 3 and the box 1 The gap is filled with cushioning material 13. Specifically, the cushioning material 13 is a sponge block. On the one hand, the sponge block has the advantage of being easy to cut and can be cut into the required irregular shape for easy production. On the other hand, the sponge block has a good The cushioning effect can cushion the impact from the outside. The upper side wall of the cylindrical shell 3 is provided with a venti...
Example Embodiment
[0024] Example 2
[0025] Such as Figure 4-5 As shown, the difference between this embodiment and the first embodiment is: the cylindrical shell 3 is provided with a magnetic floating plate 11, the magnetic floating plate 11 is provided with a plurality of water passing ports 12, and the sealing block 8 is made of ferromagnetic material. The different poles between the sealing block 8 and the magnetic floating plate 11 attract each other.
[0026] In this embodiment, when the water surface fluctuates or even tilts, the magnetic sealing plate 11 tilts with the water surface. Under the action of the magnetic force, the sealing block 8 is driven to move, which improves the sensitivity of the sealing plate 6 and further avoids water leakage.
[0027] At the same time, when the sealing plate 6 is reset, under the action of the sealing block 8, the magnetic sealing plate 11 can be reset and located in the middle part of the water surface. Since the magnetic sealing plate 11 is a grid pla...
