Description

Technical Field

[0001] The utility model relates to the field of biotechnology, and particularly relates to a low-temperature transportation device for cytokines. Background Art

[0002] When detecting cytokines, a low-temperature transportation device is required to transport cytokines at low temperature. For example, a low-temperature transportation device for cytokines disclosed in a Chinese patent with the authorized publication number CN218537526U includes a storage frame, a plurality of storage tubes with closed bottoms, and an upper cover. The outer frame of the storage frame is divided into an inner frame and an outer frame. In this low-temperature transportation device for cytokines, by setting the storage tubes, springs, and support blocks, when using this device to transport cytokines, first, the test tubes containing cytokines are placed inside the plurality of storage tubes through a plurality of mounting holes. At this time, under the action of the springs, the test tubes will not completely enter the storage tubes, but a small part will be located outside the storage frame. Then, the upper cover is covered. Under the action of the rubber soft pads at the bottom of the upper cover, each test tube is pressed into the storage tube. After the transportation is completed, the upper cover is opened. At this time, under the action of the springs, the test tubes are ejected outwards, and the staff can very conveniently take out the test tubes, improving the work efficiency and thus enhancing the practicality of this device.

[0003] However, in actual applications, the above device still has the following problems: Since a plurality of test tubes are directly placed together, when one of the test tubes needs to be taken, opening the upper cover will cause all the other test tubes to pop out and be exposed, resulting in the other test tubes being separated from the low-temperature environment and absorbing heat from the outside, reducing the activity of the cytokines in the other test tubes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a low-temperature transportation device for cytokines aiming at the above deficiencies, which can separately take and place test tubes without affecting the low-temperature environment of other test tubes and ensuring the activity of the cytokines in other test tubes.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A low-temperature transportation device for cytokines includes a box body, a box cover rotatably connected to the box body at one end through a rotating shaft, a low-temperature seat arranged in the box body, a plurality of outer tubes arranged on the low-temperature seat, test tubes inserted into the outer tubes at the bottom, a locking structure for locking the test tubes in the outer tubes, a slider slidably connected up and down in the outer tubes, a spring arranged at the bottom of the outer tubes, and the beginning and end of the spring are respectively connected to the inner side of the bottom of the outer tubes and the slider.

[0007] Further, an annular groove is arranged on the test tube, and the annular groove is arranged close to the opening of the test tube.

[0008] Further, the locking structure includes a fixed cylinder fixed at the pipe orifice of the outer pipe, a fixed disk fixed at the top end of the fixed cylinder, and a rotating disk rotatably connected to the fixed disk. Two linear guide grooves diverging outward with the axis of the outer pipe as the center are arranged on the fixed disk, and two spiral guide grooves spirally diverging outward with the axis of the outer pipe as the center are arranged on the rotating disk. A plurality of insertion through grooves are formed on the fixed cylinder. A sliding column is slidably connected in the spiral guide groove. One end of the sliding column passes through the linear guide groove and is connected with a locking block. One end of the locking block is slidably connected to the insertion through groove. When the test tube is in the inserted state, the insertion through groove faces the annular groove. A test tube passage coaxial with the outer pipe is arranged on the fixed disk and the rotating disk.

[0009] Further, a plurality of convex strips are radially arranged on the rotating disk, and the convex strips are arranged perpendicular to the screwing direction of the rotating disk.

[0010] Further, a low-temperature cavity is arranged in the low-temperature base, liquid nitrogen is filled in the low-temperature cavity, and one end of the outer pipe is inserted into the liquid nitrogen.

[0011] Further, a heat preservation and heat insulation groove is fixed in the box body, a heat preservation and heat insulation cover is arranged in the box cover. When the box body and the box cover are closed, the heat preservation and heat insulation groove and the heat preservation and heat insulation cover enclose a heat preservation and heat insulation space, and the low-temperature base is fixed in the heat preservation and heat insulation space.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In practical applications, the test tube is slid into the outer pipe, and the test tube is locked through the locking structure. At this time, the spring is compressed; when the test tube needs to be used, the test tube is loosened through the locking structure, and the restoring force of the spring is used to push the slider and the test tube to slide out of the outer pipe; the present utility model can take and place the test tube separately, without affecting the low-temperature environment of other test tubes, and ensures the activity of cytokines in other test tubes.

At this time, the spring 61 is compressed; when the test tube 7 needs to be used, the test tube 7 is loosened through the locking structure, and the slider 6 and the test tube 7 are pushed out of the outer tube 4 by the restoring force of the spring 61; the present utility model can separately take and place the test tube 7 without affecting the cryogenic environment of other test tubes 7, ensuring the activity of cytokines in other test tubes 7.

[0022] As Figures 1-6 shown, an annular groove 71 is arranged on the test tube 7, and the annular groove 71 is arranged close to the opening of the test tube 7; in this embodiment, the locking structure locks the test tube 7 in the outer tube 4 by clamping the annular groove 71.

[0023] As Figures 1-6As shown in the figure, the locking structure includes a fixed cylinder 51 fixed at the pipe orifice of the outer pipe 4, a fixed disk 52 fixed at the top of the fixed cylinder 51, and a rotating disk 53 rotatably connected to the fixed disk 52.
