[0004] Similar problems exist in the prior art and the above technical solutions. In the cold chain logistics heat preservation box technology, the sealing of the heat preservation box usually relies on the buckle structure between the box cover and the box body. Some use sealing strips for auxiliary sealing. This sealing method is relatively simple. It is difficult to completely prevent air leakage by mechanical buckling of the box cover and the edge of the box body. The heat preservation box cannot provide sufficient buffer protection for the internal materials when facing bumpy road vibration and accidental collision.

[0005] To solve the above problems, we propose a cold chain logistics heat preservation box. Utility model content

[0006] The utility model discloses a cold chain logistics heat preservation box, which solves the problem of mechanical buckling of the box cover and the edge of the box body in related technology, which is difficult to completely prevent air leakage.

[0007] The technical scheme of the utility model is as follows:

[0009] The top surface of the storage box is provided with a rectangular opening communicated to the inside of the storage box, and an elastic sealing connecting gasket is fixedly installed in the rectangular opening of the top surface of the storage box.

[0010] The storage box comprises an outer shell layer and an inner lining layer, the outer shell layer is distributed at the outermost side, and the inner wall surface of the outer shell layer is provided with a reflecting layer.

[0011] The cross section of the bolt plate and the elastic sheet is in V-shaped structure.

[0012] Further, a hollow layer forming a hollow structure is formed between the reflecting layer and the outer shell layer, and the outer shell layer and the reflecting layer are fixedly connected through a plurality of connecting blocks.

[0013] Further, an inner lining layer is fixedly attached to the side of the reflecting layer away from the outer shell layer.

[0014] Further, the inner wall structure of the heat preservation cover is the same as that of the storage box.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] 1. In the utility model, after the material is put into the storage box through the connecting opening, the threaded cap is first screwed, and the connecting opening is preliminarily sealed. At this time, the elastic sealing connecting gasket surrounds the connecting opening, and the material itself has certain flexibility and adhesion. When the heat preservation cover is put on, the bolt plate slides down along the bolt opening, and the elastic sheet cooperates with the bolt opening to limit and fix the heat preservation cover, so that the heat preservation cover is tightly attached to the limiting frame of the storage box. The elastic sealing connecting gasket fixedly installed in the rectangular opening of the top surface of the storage box further fills the gap between the storage box and the heat preservation cover during the pressing of the heat preservation cover, and cooperates with the sealing of the threaded cap to realize double sealing effect, greatly improves the sealing performance of the material in the storage box, effectively prevents the outside air from entering, reduces the temperature change in the box, and ensures the quality of the temperature-sensitive material in the cold chain logistics.

[0017] 2. In the utility model, during the cold chain logistics transportation process, the storage box will inevitably be subjected to vibration and impact. Due to the elastic characteristics of the elastic sealing connecting gasket, the elastic sealing connecting gasket can play a buffering role when the storage box is subjected to external vibration and impact. When the transport vehicle runs on a bumpy road and generates vibration, the vibration is first transmitted to the storage box. The elastic sealing connecting gasket on the top surface of the storage box can absorb part of the vibration energy before the vibration is transmitted to the material. The elastic deformation of the elastic sealing connecting gasket can disperse the vibration impact force and reduce its influence on the material in the storage box, so as to protect the material from collision damage caused by vibration and ensure the integrity of the material during transportation.

[0027] like Figs. 1-4 As shown, this embodiment proposes a cold chain logistics insulated box, including a storage box 1 and an insulated cover 3. The outer side of the storage box 1 is provided with an integrally formed limiting frame 2. The flange-shaped limiting frame 2 facilitates the handling of the storage box 1. A pin hole 4 is provided through the limiting frame 2. The bottom surface of the insulated cover 3 is provided with a pin plate 5 whose structure is adapted to the pin hole 4. The outer side of the pin plate 5 is provided with an elastic piece 6. The cross-section of the pin plate 5 and the elastic piece 6 is V-shaped.

[0028] In this embodiment, when the cover is covered, the latch plate 5 and the elastic sheet 6 slide downward along the corresponding latch hole 4, and the elastic sheet 6 is pressed against the latch plate 5 when it slides along the inner wall of the latch hole 4. When the elastic sheet 6 is completely distributed below the limiting frame 2, the elastic sheet 6 is reset and fixed to the cover 3 under the cooperation of the latch hole 4, so that the cover 3 is stably covered on the top of the storage box 1, improving the stability of the cover 3.

[0029] Further, the top surface of the storage box 1 is provided with a rectangular opening connected to the inside of the storage box 1, and an elastic sealing connecting gasket 7 is fixedly installed in the rectangular opening of the top surface of the storage box 1. The center of the elastic sealing connecting gasket 7 is fixedly spliced with a connecting plate 10, and the connecting plate 10 is fixedly installed with a connecting opening 8. The outer wall surface of the connecting opening 8 is provided with a spiral thread, and the connecting opening 8 is threadedly installed with a threaded cover 9. In use, the materials are placed into the storage box 1 through the connecting opening 8, and the materials are temporarily stored in the storage box 1. After the materials are loaded, the threaded cover 9 is first covered on the connecting opening 8 to form the first sealing, and then the cover 3 is fixedly covered on the storage box 1 to form the second sealing through the cover 3, thereby improving the sealing performance of the materials in the storage box 1. When a part of the materials needs to be taken out, the storage box 1 is controlled to be turned over, so that the side of the storage box 1 corresponding to the connecting opening 8 is distributed to the surrounding side. At this time, the threaded cover 9 is opened to facilitate the pouring of the materials through the connecting opening 8. Since the elastic sealing connecting gasket 7 has elastic characteristics, the elastic characteristics of the elastic sealing connecting gasket 7 can better control the orientation of the connecting opening 8, thereby facilitating the control of the pouring amount of the materials.

The inner wall structure of the cover 3 is the same as that of the storage box 1. By providing the reflection layer 101, the heat radiation can be reflected, and the heat transfer can be further reduced. By providing the hollow layer 102, the low thermal conductivity of air is used to enhance the heat preservation effect in the storage box 1.

[0031] After the material is put into the storage box 1 through the connecting port 8, the threaded cover 9 is screwed, and the preliminary sealing of the connecting port 8 is formed. At this time, the elastic sealing connecting gasket 7 surrounds the connecting port 8, and the material itself has certain flexibility and adhesion.
