Description

Technical Field

[0001] The utility model relates to the technical field of gas phase liquid nitrogen tanks, in particular to a gas phase liquid nitrogen tank with a protective structure. Background Art

[0002] Liquid nitrogen refers to liquid nitrogen. Liquid nitrogen is an inert, colorless, odorless, non-corrosive, non-flammable, and extremely low-temperature liquid. Liquid nitrogen is needed to lower the internal temperature when storing in a vapor phase liquid nitrogen tank. Vapor phase liquid nitrogen tanks are low-temperature storage tanks used to store large quantities of stem cells, embryos, and for preservation. Vapor phase liquid nitrogen tanks use liquid nitrogen evaporation to change liquid nitrogen from liquid to gas to cool the interior and preserve samples.

[0003] The traditional method of moving a gas-phase liquid nitrogen tank is usually to move it through the tank's own rollers. Since the rollers have no buffering function, the samples stored inside are likely to shake greatly during the movement, and the samples may fall, affecting the storage of the samples. In addition, the tank's height cannot be adjusted according to different usage requirements through the rollers it carries. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a gas-phase liquid nitrogen tank with a protective structure to solve the problem that the existing method of moving the gas-phase liquid nitrogen tank proposed in the above background technology is usually moved by the rollers of the gas-phase liquid nitrogen tank itself. Since the rollers carried by the tank itself do not have a buffering function, it is easy to cause the samples stored inside to shake greatly during the movement, and the samples may fall, affecting the storage of the samples. In addition, the rollers carried by the tank itself cannot be used to adjust the placement height of the gas-phase liquid nitrogen tank according to different usage requirements.
