[0034] Figure 2 is a cross-sectional view of a stem cell cold storage device;

[0035] Figure 3 A diagram of a door mechanism of a stem cell cold storage device;

[0036] like Figure 1-3 As shown, a stem cell cold storage device disclosed in the present invention may include: a cold storage mechanism, a door mechanism, a placement mechanism and other components;

[0037] like Figure 1-3 As shown, the refrigeration mechanism includes a refrigeration box 1, an opening 9, and an electric push rod 10;

[0038] The electric push rod 10 is installed at the center of the lower surface of the refrigerator 1, and the opening 9 is opened at the center of the upper surface of the refrigerator 1. The telescopic arm of the electric push rod 10 extends into the refrigerator 1;

[0039] The electric push rod 10 is used to refrigerate the stem cells, the electric push rod 10 is used to lift and lower the placement mechanism, and the opening 9 is used for the stem cells to enter and exit the refrigerator 1;

[0040] like Figure 1-3 As shown, the box door mechanism includes a rectangular plate 2, a bidirectional screw 3, a threaded seat 4, a box plate 5, a synchronous wheel 6, a synchronous belt 7, and a motor 8;

[0041] Two groups of rectangular plates 2 are installed on the upper surface of the cold storage box 1 and are on the side of the opening 9. Each of the bidirectional screws 3 is rotatably installed between the corresponding group of two rectangular plates 2. Each of the threaded seats 4 is arranged on the thread corresponding to the bidirectional screw 3. Each of the box plates 5 is installed between two threaded seats 4 on the same thread. Each of the synchronous wheels 6 is installed on the end of the corresponding threaded seat 4 passing through the rectangular plate 2. The synchronous belt 7 is arranged on the two synchronous wheels 6. The motor 8 is installed on the side of one of the rectangular plates 2 and the driving end is connected to the other end of the corresponding bidirectional screw 3.

[0042] When opening the opening 9, the motor 8 drives the bidirectional screw 3 connected thereto to rotate, and the rotating bidirectional screw 3 drives another bidirectional screw 3 to rotate in the same direction through the synchronous wheel 6 and the synchronous belt 7. Each rotating bidirectional screw 3 drives the two threaded seats 4 thereon to move away from each other, thereby driving the two box plates 5 to move away from each other to open the opening 9. When closing, the motor 8 only needs to drive the bidirectional screw 3 to reverse. Through the above operation, the two bidirectional screws 3 are reversed in the same direction, and the two box plates 5 are brought close to each other to close the opening 9.

[0048] When the circular groove 19 faces upward, the device can place a cylindrical container. At the same time, the two clamps 18 are pressed to disengage the clamps 14 and enter the cavity 15, so that the placement plate 13 can be released from the fixation. Then, the placement plate 13 is rotated 180 degrees around the hinge to make the rectangular groove 20 face downward. At the same time, the two clamps 18 are aligned with the other two clamps 14. The two springs 17 rebound and drive the two clamps 18 to insert into the aligned two clamps 14, so that the placement plate 13 is fixed again, and the adjustment is completed.

[0049] When in use, after the opening 9 is opened, the electric push rod 10 extends to drive the placement plate 13 to extend from the opening 9, and then the stem cell container that needs to be refrigerated is placed in the circular groove 19 adapted thereto, and then the electric push rod 10 shortens to drive the placement plate 13 to descend, thereby driving the stem cell container to descend into the refrigerator 1, and then the opening 9 is closed, and the refrigerator 1 is used to refrigerate the stem cells in the stem cell container.
