The utility model relates to the technical field of centrifugal machines, in particular to an ultralow-temperature centrifugal machine with a protective structure, which comprises a machine body, a centrifugal machine cover and a centrifugal machine cover. The protective cover is connected with the top of the machine body through a hinge; the box door is connected to the outer surface of the machine body in a hinged mode; the fixing ring is fixed in the machine body; the groove is formed in the inner ring of the fixing ring; the motor is mounted at the bottom of the machine body; and the rotating shaft is rotationally arranged on the lower portion in the machine body, and the rotating shaft is rotationally connected with the output end of the motor. The defects in the prior art are overcome, the centrifugal barrel drives the sliding ring and the rotating ball to rotate in the groove, the stability of the centrifugal barrel in the rotating period is further improved due to the fact that the fixing ring is fixe
