[0022] Combine Figure 1-Figure 5As shown, a rectangular limiting frame 11 is provided on one side of the inner cavity of the cold storage body 1 near the door, a sealing frame 2 is provided inside the rectangular limiting frame 11, both ends of the sealing frame 2 pass through the rectangular limiting frame 11 and extend to the front and rear ends thereof, wherein, a front end plate 21 is provided at one end of the sealing frame 2 located at the front end of the rectangular limiting frame 11, a rear end plate 22 is provided at one end of the sealing frame 2 located at the rear end of the rectangular limiting frame 11, and a sealing gasket 23 is provided on one end face of the front end plate 21 near the door and one end face of the rear end plate 22 near the rectangular limiting frame 11. The end plate 21 and the rear end plate 22 are respectively tightly attached to the inner wall of the warehouse door and the rear end face of the rectangular limit frame 11 through the sealing gasket 23, and the four corners of the rear end face of the rectangular limit frame 11 are threadedly installed with positioning rods 12, which pass through the rear end plate 22 and extend to its rear end. The outer wall of the positioning rod 12 is located at the rear end of the rear end plate 22 and is provided with two annular limiting plates 13 that are screwed to each other. In addition, a spring 14 is provided between the end face of the annular limiting plate 13 close to the rear end plate 22 and the rear end face of the rear end plate 22 and around the outside of the positioning rod 12.

[0023] In one embodiment, when the door is closed, the door can push the sealing frame 2 to move through the front end plate 21, so that the sealing frame 2 moves in the rectangular slot 111 inside the rectangular limit frame 11, and then the displaced sealing frame 2 drives the rear end plate 22 installed thereon to move, so that the rear end plate 22 slides on the outer wall of the positioning rod 12 through the through hole 221, and the spring 14 is squeezed on the annular limit plate 13 to deform, so that the sealing frame 2 and the front end plate 21 and the rear end plate 22 thereon can be reversely displaced under the elastic force of the spring 14, and the sealing frame 2 and the front end plate 21 and the rear end plate 22 installed thereon can be reversely displaced. The sealing gaskets 23 on the front end plate 21 and the rear end plate 22 are respectively pressed against the inner side wall of the warehouse door and the rear end face of the rectangular limit frame 11. Since the sealing gaskets 23 seal the gaps between the front end plate 21 and the inner side wall of the warehouse door and between the rear end plate 22 and the rear end face of the rectangular limit frame 11, the temperature inside the cold storage body 1 is prevented from leaking from the gaps, and the wear of the seal between the warehouse door and the container cold storage due to long-term flipping of the warehouse door is avoided, resulting in leakage of the refrigerated cavity. The sealing of the container cold storage is improved, and the use effect of the container cold storage is guaranteed.

[0024] In one embodiment, since a clamping groove 201 is provided on the outside of the sealing frame 2 between the front end plate 21 and the rear end plate 22, and the width of the clamping groove 201 is greater than the thickness of the rectangular limit frame 11, there is a moving space between the front end plate 21, the rear end plate 22 and the rectangular limit frame 11. When adjusting the position of the sealing frame 2, the front end plate 21 and the rear end plate 22 on the sealing frame 2 can be displaced on the front and rear sides of the rectangular limit frame 11 through the clamping groove 201, and the front end plate 21 and the rear end plate 22 on the sealing frame 2 will not directly interfere with the rectangular limit frame 11, thereby facilitating the position adjustment of the sealing frame 2.

[0025] In one embodiment, when installing the spring 14, the spring 14 can be first put on the positioning rod 12, and the spring 14 can be limited by the annular limit plate 13, and then the end of the positioning rod 12 away from the annular limit plate 13 can be inserted into the through hole 221, and the positioning rod 12 can be screwed to install the positioning rod 12 in the threaded hole 112 on the rear end face of the rectangular limit frame 11, and the installation of the spring 14 can be completed, so that the spring 14 can always be pressed tightly against the back of the rear end plate 22, pushing the rear end plate 22 and the front end plate 21 on the sealing frame 2 to move, so that the front end plate 21 and the rear end plate 22 are respectively close to the inner side wall of the warehouse door and the rear end face of the rectangular limit frame 11, closing the gap between the rectangular limit frame 11 and the warehouse door, thereby ensuring the use of the sealing frame 2 and realizing the sealing of the refrigerated cavity inside the container cold storage.

[0026] In one embodiment, when elastic fatigue occurs in the spring 14, the two annular limit plates 13 on the outer wall of the positioning rod 12 can be screwed through the threaded groove 131 to adjust the position of the two annular limit plates 13 on the positioning rod 12, thereby reducing the distance between the annular limit plates 13 and the rectangular limit frame 11, thereby shortening the elastic stroke of the spring 14 and extending the service life of the spring 14. This not only avoids the trouble of the spring 14 being unable to press the rear end plate 22 tightly against the rectangular limit frame 11 due to elastic fatigue and shortened stroke, but also avoids the waste of resources caused by directly replacing the spring 14, thereby ensuring the use of the spring 14.

[0027] In one embodiment, when replacing the spring 14, the positioning rod 12 can be directly screwed to remove the positioning rod 12 from the threaded hole 112, and the spring 14 mounted on the positioning rod 12 can be taken out to complete the replacement of the spring 14. The structure is simple, the operation is convenient, and it is conducive to the subsequent maintenance work.

[0028] The working principle of the present invention is as follows: when the container cold storage is in use, the door is flipped over to close the container cold storage, and the door can push the sealing frame 2 to move through the front end plate 21, so that the sealing frame 2 moves in the rectangular empty groove 111 inside the rectangular limit frame 11, and then the displaced sealing frame 2 drives the rear end plate 22 installed thereon to move, so that the rear end plate 22 slides on the outer wall of the positioning rod 12 through the through hole 221, and the spring 14 is squeezed on the annular limit plate 13 to deform, and then the sealing frame 2 and the front end plate 21 and the rear end plate 22 thereon are displaced in the opposite direction under the elastic force of the spring 14, and the sealing gaskets 23 installed on the front end plate 21 and the rear end plate 22 are respectively pressed against the inner wall of the door. The side wall and the rear end face of the rectangular limit frame 11, due to the sealing gasket 23, seals the gap between the front end plate 21 and the inner side wall of the warehouse door, and between the rear end plate 22 and the rear end face of the rectangular limit frame 11, preventing the temperature inside the cold storage body 1 from leaking from the gap, thereby achieving the seal between the warehouse door and the container cold storage, and the position of the sealing frame 2 can be adjusted by the spring 14, and the sealing frame 2 can be pressed tightly against the inner side of the warehouse door and the rectangular limit frame 11 to close the refrigerated cavity in the container cold storage, avoiding the wear of the seal between the warehouse door and the container cold storage due to long-term flipping of the warehouse door, thereby improving the sealing of the container cold storage and ensuring the use effect of the container cold storage.
