Description

Technical Field

[0001] The utility model belongs to the technical field of liquid nitrogen filling, and in particular relates to a liftable liquid nitrogen filling system. Background Art

[0002] Liquid nitrogen is an inert, colorless, odorless, non-corrosive, and non-flammable liquid obtained by mixing nitrogen gas at extremely low temperatures. Liquid nitrogen has a good preservation effect. When nitrogen needs to be added to the corresponding bottle, the corresponding liquid nitrogen filling system needs to be used.

[0003] When using a liquid nitrogen filling system to fill liquid nitrogen, the liquid nitrogen is filled into the corresponding bottle body through the filling head. However, the installation position of the filling head on some common liquid nitrogen filling systems is often fixed. When filling liquid nitrogen into bottles of different batches and models, it is inconvenient to adjust the use height of the filling head, which leads to inconvenience in use. After searching, the patent document with the authorization announcement number of CN218378964U discloses a liftable liquid nitrogen filling system. Although the filling head can be adjusted in use height, after the height adjustment of the filling head is driven by the screw rod, the filling head can only be supported and positioned by the torque of the screw rod, and the corresponding support force for the filling head is lacking, thereby reducing the stability of the filling head during use.
