The utility model relates to the technical field of
medical equipment, and particularly discloses
liquid nitrogen storage equipment which comprises a bearing frame, a transmission mechanism, a storing and taking mechanism, a lifting mechanism, a telescopic driving mechanism and a rotating mechanism, the bearing frame is arranged on a
liquid nitrogen tank, the lifting mechanism and the telescopic driving mechanism are both arranged on the bearing frame, and the rotating mechanism is arranged on a cover plug; the transmission mechanism comprises a transmission carrier plate and a transmission
assembly arranged on the transmission carrier plate. The storing and taking mechanism is arranged at the driving end of the transmission
assembly and located in the
liquid nitrogen tank. The driving end of the lifting mechanism is connected with the transmission carrier plate; the driving end of the telescopic driving mechanism is in transmission connection with the transmission
assembly; the driving end of the rotating mechanism is connected with the transmission assembly. According to the liquid
nitrogen storage device, the
cryopreservation boxes can be directly stored and taken out, the storage frame does not need to be moved, therefore, balance in the liquid
nitrogen tank cannot be disturbed, the uniformity of the temperature in the liquid
nitrogen tank is improved, liquid nitrogen consumption in the liquid nitrogen tank is reduced, and meanwhile sample damage caused by the fact that other
cryopreservation boxes are affected when the storage frame is moved is avoided.
