AI Technical Summary
During the cell transport process of existing liquid nitrogen tank baskets, cells are placed outside the liquid nitrogen tank for too long, and people have too much contact with the cells, resulting in a decrease in the cell state.
A liquid nitrogen tank carrying basket is designed, using parts such as lifting rods, baffles, and fixing blocks. By moving the lifting rods and fixing rods, the fixing rods are achieved to fix and separate the lifting rods and the basket body, reducing the time when cells are exposed to room temperature during transport and reducing the chances of people's contact with cells.
This basket can not only be used for daily cell storage, but also facilitate cell transport, reduce the time for cells to be placed outside and contact with people, ensuring the good condition of the cells.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of basket handling, and in particular to a basket handling for a liquid nitrogen tank. Background Art
[0002] Liquid nitrogen tanks can generally be divided into two types: liquid nitrogen storage tanks and liquid nitrogen transport tanks. Storage tanks are mainly used for static storage of liquid nitrogen indoors and are not suitable for long-distance transportation under working conditions. In order to meet the conditions of transportation, liquid nitrogen transport tanks have been specially designed to be shockproof. In addition to static storage, they can also be used for transportation when filled with liquid nitrogen, but violent collisions and vibrations should also be avoided.
[0003] Liquid nitrogen tank basket is a low-temperature storage tool used to store cryotubes in a liquid nitrogen tank in a low-temperature environment, so as to be able to store a large number of experimental samples or samples such as embryos and semen.
[0004] However, the hook and base of the existing liquid nitrogen tank basket are fixed structures. When transporting cells, the cells are placed outside the liquid nitrogen tank for too long, and personnel have more contact with the cells during transportation, which will deteriorate the state of the cells. Utility Model Content
[0005] In order to reduce the time that cells are placed outside the liquid nitrogen tank during transportation and reduce personnel's contact with the cells during transportation, the present application provides a liquid nitrogen tank basket.
[0006] The present application provides a liquid nitrogen tank basket, which adopts the following technical solution: it includes a basket body and a lifting rod, the upper surface of the basket body is fixedly connected with two baffles, the inner wall of each baffle is slidably connected with the outer surface of the lifting rod, the outer surface of the lifting rod is provided with a fixing hole 1, the upper surface of the basket body is fixedly connected with four fixing blocks, two handles are provided above the basket body, the inner wall of each handle is rotatably connected with the outer surface of the corresponding fixing block, and the upper surface of the basket body is provided with two fixing holes 2.
[0007] Optionally, a fixing rod is provided on the right side of the basket body, and the outer surface of the fixing rod is slidably connected to the inner wall of the first fixing hole.
[0008] Optionally, the outer surface of the fixing rod is slidably connected to the inner wall of the second fixing hole, and four placement frames are placed on the inner wall of the basket body.
[0009] Optionally, the outer surface of the basket body is provided with through holes arranged at equal distances, and the inner wall of the basket body is fixedly connected with three fixing bodies.
[0010] Optionally, a limiting hole 1 is provided on the outer surface of each of the fixing bodies, and an inner wall of each of the limiting holes 1 is slidably connected to the outer surface of the fixing rod.
[0011] Optionally, a second limiting hole is provided on the outer surface of the basket body, and the outer surface of the fixing rod is slidably connected to the inner wall of the second limiting hole.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. The utility model is provided with components such as a lifting rod, a baffle, and a fixing block. By moving the lifting rod, the bottom end of the lifting rod is moved to penetrate the two baffles, and then the fixing rod is placed and inserted into the fixing hole 1, so that the lifting rod can be fixed on the upper surface of the basket body. Otherwise, the lifting rod can be separated from the basket body. Compared with the traditional liquid nitrogen tank basket, this basket can not only be used for daily cell storage, but also for cell transportation, which can reduce the time that cells are placed outside the liquid nitrogen tank during transportation, reduce the contact of personnel with cells during transportation, facilitate the steps of cell transportation, and ensure the good state of cells.
[0014] 2. The utility model sets the basket body, the fixing rod, the fixing body and other components. After the fixing rod is inserted downward into the fixing hole 1, the fixing rod continues to be moved downward. The fixing rod will pass through the fixing hole 2 and the limiting hole 1 in sequence, and then enter the limiting hole 2, so that the fixing rod can be limited to keep the fixing rod stable. The placement frame is limited by the fixing rod, thereby further maintaining the stability of the placement frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 3 , Figure 4 The outer surface of the basket body 1 is provided with through holes 10 arranged at equal distances, and the inner wall of the basket body 1 is fixedly connected with three fixing bodies 11. By providing the through holes 10, liquid nitrogen is conveniently used to perform low-temperature storage on the cryotubes in the placement frame 9. The fixing bodies 11 are installed on the inner wall of the basket body 1, and the position of the fixing bodies 11 is located by the basket body 1.
[0023] See also Figure 3 , Figure 4 A limiting hole 12 is provided on the outer surface of each fixing body 11, and the inner wall of each limiting hole 12 is slidably connected to the outer surface of the fixing rod 8. The limiting hole 12 is provided to limit the fixing rod 8.
[0024] See also Figure 1 A fixing rod 8 is provided on the right side of the basket body 1, and the outer surface of the fixing rod 8 is slidably connected to the inner wall of the fixing hole 4. The fixing rod 8 is placed, and by inserting the fixing rod 8 into the fixing hole 4, the lifting rod 2 can be connected to the basket body 1, and the placing frame 9 is limited by the fixing rod 8, so that the placing frame 9 can be stably placed inside the basket body 1.
