Description

Technical Field

[0001] The utility model relates to the technical field of storage devices, in particular to a liquid nitrogen tank storage device. Background Art

[0002] Liquid nitrogen tanks are mainly used to store and transport liquid nitrogen, and liquid nitrogen is widely used in the fields of cryopreservation of medical and biological samples, metal processing and welding, low-temperature experiments and research, food freezing and refrigeration;

[0003] When using liquid nitrogen, the liquid nitrogen tank body is generally lifted directly, and then the liquid nitrogen in the liquid nitrogen tank is poured out for use by tilting the liquid nitrogen tank. However, since the liquid nitrogen tank and the stored liquid nitrogen have a certain weight, the pouring operation of the liquid nitrogen tank is relatively difficult. At the same time, the liquid nitrogen tank is not fixed when it is stored, which easily causes the liquid nitrogen tank to tip over. Therefore, the liquid nitrogen tank storage device disclosed in the existing publication number CN218582883U is provided with an adjustment member on the opposite sides of the liquid nitrogen tank, and the clamping member is detachably connected to the adjustment member through the screw hole on the adjustment member to clamp the liquid nitrogen tank, thereby ensuring the stability of the liquid nitrogen tank, and realizing the flipping of the liquid nitrogen tank with the help of a ring and a handle. However, in the application, since the bottom of the liquid nitrogen tank is placed on the shockproof pad, and when the liquid nitrogen tank rotates with the clamping member as the axis, the bottom of the liquid nitrogen tank moves in a circular path with the clamping member as the center. At this time, the shockproof pad will limit the movement of the bottom of the liquid nitrogen tank, thereby failing to realize the rotation of the liquid nitrogen tank. Utility Model Content
