[0026] Embodiment 1

[0027] Referring to Figures 1-4 , which is the first embodiment of the present utility model, a cord mesenchymal stem cell storage device is provided, mainly including:

[0028] Storage box 100, as shown in Figure 1 , on one side of the storage box 100, there is an access opening. The number of access openings is the same as that of the carrier plate 300 and they correspond one by one. An opening and closing door 101 is hermetically installed in the access opening. The movable side of the opening and closing door 101 is fixedly connected to the storage box 100 through a lock body, which is convenient for opening. A transparent observation window 102 is provided on the opening and closing door 101, which is convenient for the staff to view the internal situation of the storage box 100, so as to conveniently rotate the stem cell storage tank 500 to be taken out to the access opening. In addition, when the stem cell storage box 500 is refrigerated by introducing liquid nitrogen during specific use, it belongs to the prior art and will not be elaborated here.

[0029] Rotating mechanism 200, as shown in Figure 3 , the rotating mechanism 200 includes a rotating shaft 201 that is rotatably connected to the center of the inside of the storage box 100 through a bearing and is vertically arranged, and a rotating motor 202 that is fixedly connected to the top of the storage box 100. The bottom output end of the rotating motor 202 is fixedly connected to the top end of the rotating shaft 201.

[0030] Carrier plate 300, as shown in Figure 2 , the carrier plate 300 is fixedly sleeved outside the rotating shaft 201.

[0031] Positioning mechanism 400, as shown in Figure 2 , the positioning mechanism 400 is fixedly connected to the top of the carrier plate 300.

[0032] Stem cell storage tank 500, as shown in Figure 2 , the stem cell storage tank 500 is arranged in the positioning mechanism 400, and the stem cell storage tank 500 is fixed by the positioning mechanism 400.

[0033] Specifically, there are several positioning mechanisms 400, which are fixedly arranged on the upper surface of the carrier plate 300 in a circular array, and can fix several stem cell storage tubes 500.

[0034] Specifically, as shown in Figure 4 , the positioning mechanism 400 includes a semi-circular ring 401 fixedly connected to the top of the carrier plate 300, a U-shaped frame 402 fixedly connected to the open end of the semi-circular ring 401, and a clamping member connected to the U-shaped frame 402. The semi-circular ring 401 is adapted to the stem cell storage tank 500, and can better fix the stem cell storage tank 500.

[0035] The clamping member includes a sliding rod 403 slidably connected to the U-shaped frame 402, an arc-shaped clamping plate 404 fixedly connected to one end of the sliding rod 403, and a limiting plate 405 fixedly connected to the other end of the sliding rod 403. A spring 406 is fixedly connected between the limiting plate 405 and the U-shaped frame 402. The spring 406 is movably sleeved outside the sliding rod 403. The inner side of the arc-shaped clamping plate 404 is arranged opposite to the inner side of the semi-circular ring 401.

[0036] Furthermore, the U-shaped frame 402 is arranged near the edge of the bearing plate 300. The open end of the U-shaped frame 402 is correspondingly arranged with the inner side of the semi-circular ring 401, and the U-shaped frame 402 and the semi-circular ring 401 are integrally connected, which is convenient for production and manufacturing.

[0037] In summary, when in use and fixing the stem cell storage tank 500, first, one hand pulls the sliding rod 403 backward through the limiting plate 405. The sliding rod 403 drives the arc-shaped clamping plate 404 to move backward, expanding the distance between the arc-shaped clamping plate 404 and the semi-circular ring 401. The other hand places the stem cell storage tank 500 into the semi-circular ring 401 and makes the side of the stem cell storage tank 500 fit with the inner side of the semi-circular ring 401. Then, slowly release the limiting plate 405. The sliding rod 403 moves toward the semi-circular ring 401 under the resilience of the spring 406. The sliding rod 403 drives the arc-shaped clamping plate 404 to move synchronously until the arc-shaped clamping plate 404 clamps the surface of the stem cell storage tank 500. Through the clamping action of the arc-shaped clamping plate 404, the stability of the stem cell storage tank 500 can be improved, so that when the bearing plate 300 rotates or the stem cell storage tank 500 is taken or placed, the phenomenon that the stem cell storage tank 500 topples is not likely to occur. In addition, when taking the stem cell storage tank 500 deep in the storage box 100, start the rotating motor 202. The rotating motor 202 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the bearing plate 300 to rotate. The bearing plate 300 drives the stem cell storage tank 500 on the top to rotate until the stem cell storage tank 500 to be taken deep is rotated to the access opening, which is convenient for the staff to take.

[0038] It should be noted that: the whole device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure thereof will not be elaborated here.

[0039] It should be explained that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
