Description

Technical Field

[0001] The utility model relates to the technical field of cell freezing, in particular to a cell freezing box. Background Art

[0002] Cryopreservation is a common method of cell preservation, which freezes cell samples at extremely low temperatures to slow down the metabolic activity and growth of cells, thereby achieving the purpose of long-term preservation. This method is widely used in biomedical research, biotechnology, pharmaceutical industry and other fields.

[0003] When cells are frozen, the cell suspension is placed in a cryotube, and usually multiple cryotubes are stored together in a cryobox for cell freezing. Therefore, multiple cryotubes are generally stored in a cryobox at the same time. Although labels are provided on the cryotubes in the prior art, there are many cryotubes in the cryobox, and when they are densely arranged, it is difficult for operators to find the required cryotubes at the first time through the labels. In addition, the gradient cooling box in the prior art mostly adopts a rotating cover design, but after the gradient cooling box is placed in a -80°C refrigerator for freezing, its rotating cover is difficult to open, which is inconvenient to use. Utility Model Content

[0009] Through the above technical solution, the box body can be easily taken through the handle, and the box cover and the box body are detachably connected, which is convenient for use. One side of the box body is stepped, and the cryopreservation tubes are distributed in a stepped manner, that is, there is a height difference between them, so that the labels on the cryopreservation tubes can be exposed, which is convenient for operators to take.

[0010] As a further improvement of the above solution, an upper positioning hole and a lower positioning hole are opened on the top of the box body, and the upper positioning hole is a through hole.

[0011] As a further improvement of the above solution, anti-slip protrusions are fixedly provided on both sides of the box body, and anti-slip protrusions are also provided on corresponding positions of the inner wall of the box cover.

[0012] Through the above technical solution, the anti-drop protrusion can prevent the box cover from falling off.

[0013] As a further improvement of the above solution, ribs are fixedly provided on both sides of the box body.

[0014] Through the above technical solution, the box cover can be limited and the box cover can also be supported from the bottom, which makes it easy to install the box cover.

[0015] As a further improvement of the above solution, the positioning clamping structure includes a spring and a positioning piece, the spring and the positioning piece are fixedly connected to the bottom surface of the box cover, and the position of the spring corresponds to the position of the upper positioning hole, and the positioning piece corresponds to the position of the lower positioning hole. A blocking block is also fixedly connected to the spring.

[0016] Through the above technical solution, the spring is made of elastic material and cooperates with the blocking block, so that it will bend toward one side when not under stress. In the vertical state (under stress), it can pass through the upper positioning hole.

[0017] As a further improvement of the above solution, a pull ring is fixedly connected to the box cover.

[0018] As a further improvement of the above solution, anti-slip grooves are provided on the handle.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] Please combine Figure 1 - Figure 4 A cell freezing box of this embodiment includes two major parts: a box body 1 and a box cover 9.

[0029] First, one side of the box body 1 is arranged in a stepped shape. In the present embodiment, a total of four stepped structures are provided, and seven parallel cryotube accommodating chambers 2 are provided at each step position, wherein cell cryotubes can be placed in the cryotube accommodating chambers 2. Since the cryotube accommodating chambers 2 are arranged in a stepped shape, there are differences in the height of the cell cryotubes, and when the box cover 9 is open, the labels on the cryotubes can be easily identified. However, the existing cryotube accommodating chambers 2 include cryotubes that are densely distributed at the same height, and it is difficult for operators to see the labels on the cryotubes clearly at the first time. Therefore, this stepped distribution can expose the cryotube labels, making it convenient for staff to identify and take them.

[0030] In addition, because the box body 1 is also fixedly provided with a handle 3 , and the handle 3 is provided with anti-slip grooves 4 , the box body 1 can be conveniently picked up with one hand through the handle 3 .

[0031] The box cover 9 is detachably connected to the box body 1, and the box cover 9 is installed on the box body 1. In order to connect and fix the box cover 9 to the box body 1, an upper positioning hole 5 and a lower positioning hole 6 are provided on the box body 1. The upper positioning hole 5 is located above the cryopreservation tube accommodating cavity 2 arranged in a stepped shape, and the upper positioning hole 5 is a through hole, and the lower positioning hole 6 is located below the cryopreservation tube accommodating cavity 2 arranged in a stepped shape. Correspondingly, a positioning clamping structure 10 is also provided on the box cover 9.

[0032] Specifically, the positioning clamping structure 10 includes a spring 11 and a positioning piece 12, wherein the position of the spring 11 corresponds to the position of the upper positioning hole 5, the spring 11 is made of elastic material, the lower end of the spring 11 is bent, and a blocking block 13 is fixedly connected to one side of the spring 11. The shape of the upper positioning hole 5 is adapted to the shape of the spring 11 and the blocking block 13, and the spring 11 is in a vertical state.

[0033] In addition, the position of the positioning piece 12 corresponds to the position of the lower positioning hole 6, and the positioning piece 12 can be inserted into the lower positioning hole 6. That is, when the box cover 9 is installed on the box body 1, the spring piece 11 passes through the upper positioning hole 5, and the positioning piece 12 is inserted into the lower positioning hole 6. In addition, the part of the spring piece 11 that passes through the upper positioning hole 5 is bent toward one side, and cooperates with the blocking block 13 to clamp the box cover 9 to prevent the box cover 9 from falling off.

[0034] In addition, anti-drop protrusions 7 are provided on the side of the box body 1 and the inner wall of the box cover 9 to increase the stability of the box cover 9 and prevent the box cover 9 from falling off. A retaining edge 8 is also fixedly provided on the side of the box body 1 to facilitate the installation of the box cover 9.

[0035] In order to facilitate taking or removing the box cover 9 , a pull ring 14 is fixedly connected to the box cover 9 .

[0037] (I): First, the cryopreservation tubes can be arranged in a stepped manner in the cryopreservation tube accommodating chamber 2, and the positions of the cryopreservation tubes are different, so that the cryopreservation tube labels are exposed, and the operator can easily identify the labels on the cryopreservation tubes. The operator can easily identify and take the corresponding cryopreservation tube.

[0038] (II): When the box cover 9 and the box body 1 are closed, align the spring 11 and the positioning piece 12 with the upper positioning hole 5 and the lower positioning hole 6, and press the box cover 9 downward. The spring 11 passes through the upper positioning hole 5, and the positioning piece 12 is inserted into the lower positioning hole 6. In addition, the spring 11 that passes through the upper positioning hole 5 is bent toward one side, and cooperates with the blocking block 13 to clamp the box cover 9 to prevent the box cover 9 from falling off. In addition, the anti-fall-off protrusions 7 provided on the box body 1 and the box cover 9 can also prevent the box cover 9 from falling off.
