Detailed implementation mode

[0018] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Apparently, the described embodiments are only one embodiment of the present application, rather than all embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0019] Unless otherwise defined, the technical terms or scientific terms used in the present application shall have the ordinary meanings understood by those of ordinary skill in the art to which the present application pertains.

[0020] This embodiment provides a biological sample storage device 10. Figure 1 It is a schematic structural diagram of the biological sample storage device 10 according to some embodiments of the present application; Figure 2 It is a schematic structural diagram of the biological sample storage device 10 according to some embodiments of the present application after the box body 100 and the driving device are hidden; Figure 3 It is Figure 2 A first perspective view of the shown structure after the cryopreservation rack 300 is hidden; Figure 4 It is Figure 2 A second perspective view of the shown structure after the cryopreservation rack 300 is hidden.

[0021] The biological sample storage device 10 includes a box body 100, a fixing device 200, at least one cryopreservation rack 300 and a driving device. The box body 100 defines a receiving cavity; the fixing device 200 is disposed in the receiving cavity and fixed to the box body 100; at least one cryopreservation rack 300, the at least one cryopreservation rack 300 is disposed in the receiving cavity, each cryopreservation rack 300 has a storage position for storing biological samples, and each cryopreservation rack 300 is fixed to the fixing device 200 so that the relative position of each storage position and the fixing device 200 is fixed; the driving device, the driving device is disposed in the receiving cavity, the driving device is connected to a picking and placing device to drive the picking and placing device to move, so as to pick and place the biological samples stored in the at least one cryopreservation rack 300, and the driving device is fixed to the fixing device 200 so that the relative position of the driving device and the fixing device 200 is fixed.

[0022] The cryogenic storage rack 300 and the driving device of this biological sample storage device 10 are both positioned with the fixing device 200 as the positioning reference. As a result, the relative positional relationship between the cryogenic storage rack 300 and the driving device is relatively fixed, and it is not easy to have problems with inaccurate picking and placing positions. If the box body 100 is directly used as the positioning reference, due to the large size and complex structure of the box body 100, it is difficult to ensure dimensional accuracy.

[0023] The box body 100 is usually assembled by means such as welding. It is difficult to ensure the dimensional accuracy of the box body 100 by means such as welding. Therefore, when both the cryogenic storage rack 300 and the driving device are fixed to the box body 100, it is easy to have problems with inaccurate picking and placing positions. Moreover, the box body 100 needs to be filled with heat-insulating materials such as foam. These heat-insulating materials will squeeze the box body 100, easily causing the box body 100 to deform, and thus it is easy to have problems with inaccurate picking and placing positions. Specifically, the fixed connection method can be various methods such as bolt connection and pin.

[0024] The fixing device 200 includes a bottom plate 210 and at least one upright column 220. The bottom plate 210 is fixedly connected to the box body 100, and at least one cryogenic storage rack 300 is fixed to the upper end of the bottom plate 210. Each upright column 220 is fixed to the upper end of the bottom plate 210, and a connecting member 230 is fixed to the upper end of each upright column 220. The connecting member 230 is fixedly connected to the driving device. This method of the bottom plate 210 and the upright column 220 is convenient for installation, has a stable structure, and a firm fixing effect. In other embodiments, the fixing device 200 can also be other structures, such as a positioning rod behind all the cryogenic storage racks 300, and there is a connecting member 230 on the positioning rod and other methods.

[0025] In some embodiments, a plurality of the cryogenic storage racks 300 are fixedly arranged at intervals on the upper end of the bottom plate 210, thereby increasing the storage capacity. In some embodiments, an opening is formed in the middle of the bottom plate 210, thereby reducing the weight and cost.

[0026] Among them, each upright column 220 can be made of a metal material. An insulating member 240 can be connected to the upper end of each upright column 220, and the upright column 220 is connected to the connecting member 230 through the insulating member 240. The insulating member 240 can be a non-metallic material such as rubber and plastic, so as to avoid the propagation of cold to the vicinity of the driving device, thereby ensuring the normal operation of the driving device.

[0027] The at least one upright column 220 includes a first upright column 220 fixed to the front end of the transverse first end at the upper end of the bottom plate 210, a second upright column 220 fixed to the rear end of the transverse first end at the upper end of the bottom plate 210, a third upright column 220 fixed to the front end of the transverse second end at the upper end of the bottom plate 210, and a fourth upright column 220 fixed to the rear end of the transverse second end at the upper end of the bottom plate 210. Thereby, the overall structure of the fixing device 200 is made more stable, and the change of the positional relationship of each structure is avoided.

[0028] The connecting member 230 includes a first connecting member 230 connecting the heat insulation member 240 at the upper end of the first upright column 220 and the heat insulation member 240 at the upper end of the second upright column 220, a second connecting member 230 connecting the heat insulation member 240 at the upper end of the third upright column 220 and the heat insulation member 240 at the upper end of the fourth upright column 220, and a third connecting member 230 connecting the rear end of the first connecting member 230 and the rear end of the second connecting member 230. The third connecting member 230 is fixed to the box body 100. Thereby, the overall structure of the fixing device 200 is further made more stable, and the change of the positional relationship of each structure is further avoided.

[0029] In some embodiments, a first fixing member 250 is connected to the upper ends of the first upright column 220 and the second upright column 220, and a second fixing member 260 is connected to the upper ends of the third upright column 220 and the fourth upright column 220. In some embodiments, a third fixing member 270 is connected to the lower ends of the first upright column 220 and the second upright column 220, and a fourth fixing member 280 is connected to the lower ends of the third upright column 220 and the fourth upright column 220. Thereby, the overall structure of the fixing device 200 is further made more stable, and the change of the positional relationship of each structure is further avoided.

[0030] Wherein, the third fixing member 270 and / or the fourth fixing member 280 can be fixedly connected to the bottom plate 210, so as to avoid the problem of inaccurate picking and placing positions when picking and placing biological samples.

[0031] For the embodiments of the present application, it should also be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0032] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be subject to the protection scope of the claims.
