Description

Technical Field

[0001] This utility model relates to the field of cryopreservation technology, and in particular to a lifting device for cryopreservation racks. Background Technology

[0002] Liquid nitrogen tanks are commonly used cryogenic storage tools for storing and transporting frozen products, playing a crucial role in biomedical experiments. A liquid nitrogen tank carrying container is an accessory that facilitates the storage and retrieval of frozen products. When freezing is required, the container is used to store cryovials, and the container is placed into the liquid nitrogen tank through the top cover. After freezing is complete, the top cover of the liquid nitrogen tank is opened, the carrying container is removed from the tank, and the cryovials placed inside the container can be taken out.

[0003] Because the cryogenic racks have a certain weight and are located in a low-temperature environment, operators cannot remove them directly by hand and usually need to use a lifting mechanism to remove them.

[0004] Existing lifting mechanisms typically only have the function of lifting up and down, which is not user-friendly or easy to use. Utility Model Content

[0049] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 2As shown, this embodiment of the invention provides a lifting device for cryopreservation racks, including: an annular mounting cylinder 1, a rotating assembly 2, a lifting assembly 3, and a gripping assembly 4. The mounting cylinder 1 is installed below the opening of a liquid nitrogen tank, with an installation opening 11 formed between the middle of the mounting cylinder 1 and the opening of the liquid nitrogen tank. The rotating assembly 2 is mounted on the mounting cylinder 1. The lifting assembly 3 is rotatably mounted within the installation opening 11 and connected to the rotating assembly 2. The gripping assembly 4 is mounted on the lifting assembly 3.

[0051] In use, the rotating component 2 drives the lifting component 3 to rotate. After rotating to the correct position, the lifting component 3 moves, and the gripping component 4 installed on the lifting component 3 fixes the cryopreservation rack. After the cryopreservation rack is fixed on the gripping component 4, the lifting component 3 rises to transport the cryopreservation rack to the outside of the liquid nitrogen tank.

[0052] More specifically, such as Figure 1 and Figure 2 As shown, the lifting assembly 3 includes: a mounting frame 31, a first linear motion mechanism 32, and a second linear motion mechanism 33. The mounting frame 31 is mounted on the inner wall of the mounting cylinder 1. The first linear motion mechanism 32 is mounted on the mounting frame 31. The second linear motion mechanism 33 is mounted on the first linear motion mechanism 32, and the second linear motion mechanism 33 moves along the axis of the liquid nitrogen tank under the drive of the first linear motion mechanism. The gripping assembly 4 is mounted on the second linear motion mechanism 33.

[0053] During the lifting and lowering process, the first linear motion mechanism 32 drives the second linear motion mechanism 33 to lift and lower. At the same time, the gripping component 4 installed on the second linear motion mechanism 33 is driven to descend to the designated position by the second linear motion mechanism 33. Then, the gripping component 4 fixes the cryopreservation rack. Then, both the second linear motion mechanism 33 and the first linear motion mechanism 32 rise, driving the cryopreservation rack to rise until the cryopreservation rack is transported out of the liquid nitrogen tank.

[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting cylinder 1 includes a first cylinder 12 and a second cylinder 14. One end of the first cylinder 12 is mounted on the inner wall of the liquid nitrogen tank, and a mounting groove 13 is provided on the inner wall of the end of the first cylinder 12 away from the tank opening. The second cylinder 14 is rotatably mounted in the mounting groove 13, and a first linear motion mechanism 32 is mounted on the inner wall of the second cylinder 14.

[0055] In use, to facilitate the rotation of the rotating component 2 and the lifting component 3, the mounting cylinder 1 includes a first cylinder 12 and a second cylinder 14. The first cylinder 12 is provided with a mounting groove 13 at the end away from the opening of the liquid nitrogen tank, and the second cylinder 14 is rotatably mounted in the mounting groove 13.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the rotating assembly 2 includes a driving gear 21, a driven gear 22, and a drive motor 23. The driving gear 21 is installed in the mounting groove 13. The driven gear 22 is installed at one end of the second cylinder 14, and after installation, the driven gear 22 is located in the mounting groove 13 and meshes with the driving gear 21. The drive end of the drive motor 23 is connected to the driving gear 21.

[0057] In use, the drive motor 23 drives the active gear 21 to rotate. The active gear 21 meshes with the driven gear 22, which drives the lifting assembly 3 installed on the second cylinder 14 to rotate, so that the gripping assembly 4 on the lifting assembly 3 can be rotated to a preset position. Then, the cryogenic rack placed in the liquid nitrogen tank can be gripped by the gripping assembly 4.

[0058] In one embodiment, such as Figure 1 and Figure 2 As shown, the gripping assembly 4 includes: a telescopic rod 41, a mounting base 42, a first clamping plate 43, a second clamping plate 44, and a rotary motor 45. One end of the telescopic rod 41 is connected to the second linear motion mechanism 33. The mounting base 42 is installed at the movable end of the telescopic rod 41. The first clamping plate 43 is installed on the mounting base 42 and is horizontally positioned after installation. The second clamping plate 44 is rotatably installed on the mounting base 42. The rotary motor 45 is installed on the mounting base 42 and connected to the second clamping plate 44, driving the second clamping plate 44 to close with the first clamping plate 43.

[0059] During the gripping process, the telescopic rod 41 extends and retracts to adjust the positions of the first clamping plate 43 and the second clamping plate 44 according to the position of the cryopreservation rack. Then, the first clamping plate 43 extends into the handle at the top of the cryopreservation rack, and then the motor 45 is rotated to drive the second clamping plate 44 to rotate and close. After the second clamping plate 44 and the first clamping plate 43 are closed, the handle of the cryopreservation rack is fixed.

[0060] In one embodiment, such as Figure 1 and Figure 2 As shown, the first linear motion mechanism 32 and the second linear motion mechanism 33 have the same structure.

[0061] More specifically, the first linear motion mechanism 32 includes a rotating lead screw 321, a lead screw nut 322, and a lifting motor 323. The rotating lead screw 321 is vertically mounted on the mounting bracket 31. The lead screw nut 322 is mounted on the rotating lead screw 321, and the second linear motion mechanism 33 is mounted on the lead screw nut 322. The lifting motor 323 is mounted on the mounting bracket 31 and connected to one end of the rotating lead screw 321.

[0062] When lifting is required, the rotating motor 45 drives the rotating lead screw 321 to rotate, and during the rotation of the rotating lead screw 321, the lead screw nut 322 moves on the rotating lead screw 321.

[0063] It should be noted that the rotating lead screw 321, lead screw nut 322, and lifting motor 323 are combined to form a lead screw pair, which facilitates the up and down movement of the gripping component 4.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
