[0068] It should be noted that the sealing door device of the present invention is applied to cryogenic storage systems or equipment. In some cases, the low-temperature environment of liquid nitrogen in the cryogenic storage system may have a certain impact on the electric drive components of the equipment. The sealing door disclosed in the present invention uses only one drive to achieve driving and sealing in different directions and dimensions, which not only reduces costs, but also reduces the impact of the cryogenic storage environment on the drive components on the door, improves the stability of equipment operation, and ensures the durability of reliable cryogenic environment.

[0069] In summary, this invention simplifies the power system and reduces costs by using the same power source for both the movement and pressing of the door body 1. The connection between the drive component 21 and the top-pressing drive component 2 and the insulated door simplifies the number of connections within a limited space and reduces the number of pre-drilled holes on the door, thereby ensuring the thickness of the insulation layer and improving the insulation function. Furthermore, the drive component 21 and the top-pressing drive component 2 can press the insulated door against the access channel, and the sealing strip on the door body 1 provides a better sealing effect.
