The other side surface of the cylinder 31 is fixedly connected with a disc column 34, the outer surface of the disc column 34 is penetrated by a limiting block 35, the limiting block 35 is fixedly arranged inside the box body 1, the limiting block 35 is made of rubber materials, the bottom surface of the limiting block 35 is fixedly connected with a fixed rod 36, the bottom surface of the fixed rod 36 is fixedly connected with a balancing weight 37, the outer surface of the limiting block 35 is attached to the inner surface of a groove of the disc column 34, the disc column 34 and the cylinder 31 form a rotating structure with the box body 1, under the action of gravity and the like, the balancing weight 37 and the storage box 32 always pull the cylinder 31 and the disc column 34, so that the centers of the two can be always vertical to the ground, and the limiting block 35 made of rubber material is always contacted with the disc column 34, make stopper 35 reach stopper 35 again after can weakening the shake of box 1, effectual holistic stable effect of improvement.

The working principle is as follows: when the storage device for improving the transportation stability of the stem cells is used, a power supply is connected to the device, according to the figures 1, 2, 4, 5 and 6, the cell test tubes 33 are firstly placed in the storage box 32, then the sealed heat-insulating cover plate 2 is covered, liquid nitrogen is poured into the storage cavity 13, the air inlet check valve 14 is installed, the temperature guide plate 15 transmits the external temperature to the liquid nitrogen in the storage cavity 13, the liquid nitrogen is subjected to temperature conduction to emit cold air, the motor 4 on the box body 1 is driven, the motor 4 drives the fixing columns 5 to drive the running wheels 6 to rotate, the running wheels 6 can drive the whole body to run, the running wheels 6 also drive the connecting disc 7 to rotate when rotating, the connecting disc 7 can intermittently extrude the square plates 8 under the action of the return spring 9, the square plates 8 slide up and down in a reciprocating manner to intermittently extrude the air bags 10, at the moment, the air bags 10 suck the cold air through the one-way suction valve 11, then the cell test tube 33 is refrigerated and insulated by leading the cell test tube into the inner cavity 3 through the one-way air outlet valve 12, and the vibration generated in the driving process can be transmitted to the limiting block 35, the limiting block 35 is made of rubber materials, the vibration can be weakened through self toughness and elasticity and then transmitted to the disc column 34, so that the vibration force applied to the disc column 34 is smaller, and meanwhile, the fixing rod 36 on the disc column 34 can keep the storage box 32 on the cylinder 31 in a vertical state with the ground as much as possible under the action of the balancing weight 37, and the stability is improved;

in the driving process, according to fig. 1, fig. 2, fig. 3, fig. 4, fig. 6, fig. 7 and fig. 8, when the driving wheel 6 is driven by the auxiliary wheel 16 to move integrally, and at this time, the auxiliary wheel 16 is also driven to rotate along with the cylindrical block 17 through the track 18, so that the cylindrical block 17 can drive the connecting column 19 to rotate through the track 18, and the connecting column 19 can drive the transmission gear 20 to rotate, and at this time, the transmission gear 20 is meshed with the driven gear 21, so that the fan blades 22 on the driven gear 21 are rotated through the supporting columns 23, the circulation of cold air inside the inner cavity 3 is accelerated under the action of the fan blades 22, and at this time, the transmission gear 20 also drives the first magnetic block 24 to rotate and intermittently generate a repulsive force to the second magnetic block 25, so that the second magnetic block 25 can push and pull the push plate 28 back and forth under the auxiliary actions of the fixing plate 26 and the fixing spring 27, make push pedal 28 can drive fixed block 29 reciprocating motion, clean the ground in the place ahead that auxiliary wheel 16 traveles through the brush 30 that cleans on the fixed block 29 to make auxiliary wheel 16 can steadily get through, prevent to vibrate, increased holistic practicality.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes, modifications, equivalents, and improvements may be made without departing from the spirit and scope of the invention.
