Technical Field

[0001] The utility model belongs to the technical field of novel cell liquid nitrogen tanks, and in particular relates to a novel cell liquid nitrogen tank which is convenient for storage. Background Art

[0002] With the continuous advancement of science and technology, especially in the field of biology, new cell types may be identified in different tissues, organs or special physiological and pathological conditions. These new cells may have unique biological characteristics, functions and potential application values, providing new clues and directions for understanding life phenomena and developing new treatments.

[0003] For example, a Chinese patent with a publication number of CN219970725U discloses a liquid nitrogen tank for cell storage, which relates to the field of cell storage technology, including a liquid nitrogen tank body, a plurality of movable supporting foot devices and a plurality of shock absorbing devices, wherein the plurality of movable supporting foot devices are fixedly connected to the side wall of the liquid nitrogen tank body, and the plurality of shock absorbing devices are fixedly connected to the top of the liquid nitrogen tank body. By means of the provided shock absorbing devices, when a vehicle bumps during the transportation of cells, the liquid nitrogen tank body will be squeezed and contracted toward the support frame, and at the same time, the support frame will apply force to the second spring through the movable block, and the liquid nitrogen tank body will also apply squeezing force to the collar and the hydraulic rod at the same time, and the collar will transmit the force generated by the liquid nitrogen tank body to the first spring, and the mutually coordinated elastic force of the two springs will be used for buffering and shock absorption, thereby avoiding collision during the operation of the liquid nitrogen for cell storage, which will lead to problems that are not conducive to cell storage.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: after the above device is moved to a suitable position, it may collide with the ground due to insufficient contact area with the ground, causing the entire device to tilt, affecting the preservation effect of the cell sample. At the same time, the above device cannot fix the new cells when in use, causing the new cells to be knocked down by the user when they are stored or taken out. In view of this, we propose a new cell liquid nitrogen tank that is easy to store. Utility Model Content
