Description

Technical Field

[0001] This utility model relates to the technical field of liquid nitrogen storage operation boxes, and in particular to a liquid nitrogen storage operation box. Background Technology

[0002] Liquid nitrogen storage control box is a storage device that uses nitrogen to reduce humidity and prevent oxidation. Liquid nitrogen storage systems are used in livestock stations for frozen semen storage, hospital blood banks, stem cell banks, etc.

[0003] Existing liquid nitrogen storage and handling boxes typically involve placing tubular or other shaped objects inside. The boxes are then moved using wheels at the bottom and a handrail on one side, allowing for simultaneous storage and transport of objects. However, the lack of internal restraint mechanisms for tubular objects means that they may shake and tip over when the box is moved, affecting the proper storage of contents. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a liquid nitrogen storage and operation box.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a liquid nitrogen storage and operation box, including a box body, lifting wheels at the bottom of the box body, a box cover at the top of the box body, multiple buckles on one side of the box cover, multiple LED bulbs on the side of the box body near the box cover, a viewing window on one side of the box body, a handrail on one side of the box body, a storage device between the box body and the handrail, and a limiting device inside the box body, the limiting device including a slot formed on one side of the inner wall of the box body, with a cylindrical block fixedly connected to the inner wall of the slot. A first circular hole block is fitted onto the surface of a cylindrical block. The size and shape of the surface of the first circular hole block are adapted to the size and shape of the inner wall of the slot. A concave rod is fixedly connected to one side of the first circular hole block. A rectangular groove is opened on one side of the concave rod. Multiple circular holes are opened on one side of the concave rod. A pin is slidably connected to the inner wall of the circular holes. A second circular hole block is slidably connected to the inner wall of the rectangular groove. The surface of the pin is slidably connected to the inner wall of the second circular hole block. A ring is fixedly connected to one side of the second circular hole block. A notch is opened on the side of the ring so that an instrument can be placed into the ring through the notch.

[0006] The effect achieved by the above components is as follows: by setting a limiting device, the concave rod is first manually moved so that it drives the first round hole block to move. When the first round hole block moves to the position where it is inserted into the slot, the cylindrical block is inserted into the first round hole block, so that the concave rod is connected and fixed to the box. At this time, the ring is manually moved so that the ring drives the second round hole block to slide left and right along the inside of the rectangular groove. When the second round hole block moves to the position where the inner wall coincides with the inner wall of any round hole, the pin is manually moved so that the pin moves to the position where it is inserted into the round hole and the second round hole block to limit the second round hole block, thereby achieving the adjustment and fixation of the ring position.

[0007] Preferably, the surface of the ring is provided with a groove, and an arc-shaped plate is slidably connected inside the groove.

[0008] The effect achieved by the above-mentioned components is that by sliding the arc plate in the groove, the sliding arc plate can block the notch on the side of the ring, thereby fixing the object inside the ring.

[0009] Preferably, the storage device includes a rectangular block, which is fixedly connected to the body. A circular hole rod is fixedly connected to one side of the rectangular block. A plurality of second threaded holes are opened on one side of the circular hole rod. Bolts are threadedly connected to the inner wall of the second threaded holes. The inner wall of the circular hole rod is slidably connected to the surface of the handrail. A circular groove is opened on one side of the handrail. The surface size and shape of the bolt are adapted to the size and shape of the inner wall of the circular groove.

[0010] The effect achieved by the above components is as follows: By setting up a storage device, the handrail is first manually moved so that it moves up and down along the inside of the circular hole rod. When the handrail moves to the position where the inner wall of the circular groove coincides with the inner wall of any of the second threaded holes, the bolt is manually turned so that the bolt is fully turned into the position of the second threaded hole and the circular groove to fix the position of the handrail, thereby completing the height adjustment and removal of the handrail. At the same time, the above steps can be reversed to store the handrail inside the circular hole rod, completing the removal and storage of the handrail. This reduces the impact of the high height of the handrail on the subsequent removal of objects inside the box and the stacking of the box, and improves the convenience of moving the box.

[0011] Preferably, one end of the bolt is fixedly connected to an auxiliary rod, and the surface of the auxiliary rod is rectangular.

[0012] The effect achieved by the above-mentioned components is that by setting up an auxiliary rod, personnel can quickly rotate the bolt by manually turning the auxiliary rod, thereby improving the convenience and stability of manually rotating the bolt.

[0013] Preferably, a reinforcing block is fixedly connected to one side of the rectangular block, and the reinforcing block is fixedly connected to the box body.

[0014] The effect achieved by the above components is that by setting up reinforcing blocks, the connection between the rectangular blocks and the box can be reinforced, reducing the possibility of the rectangular blocks separating from the box during use.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, a limiting device is set to assist in limiting the tubular objects stored inside the box, reducing the possibility of the tubular objects inside the box shaking and tipping over when the box is moved, thus affecting the normal storage of the objects inside the box and improving the storage stability of the tubular objects inside the box.
