[0002] The cell cryopreservation tube, also called the cryopreservation tube, is the experimental equipment commonly used in the biological scientific research and medical field, is mainly used for the transfer, low temperature transportation and storage of biological samples such as cells, tissues, DNA, RNA, the tube body is uniform and transparent, the state of sample is convenient for observation, has the characteristics of ultra-low temperature resistance and repeated freeze-thawing, is suitable for the long-term low-temperature refrigeration of cells and tissues;

[0003] At present, most of the cell cryopreservation tubes are long columnar, cooperate with knob cover use, but in the actual use process, the following defects are improved due to simple structure:

[0004] 1, the sealing effect is first, usually the tube body and the cover are connected through the thread (internal thread or external thread) structure, the rubber pad is arranged on the contact surface of the tube body and the cover, but only single-layer sealing, and it is not convenient to design double sealing, and the leakage and pollution that may occur during the storage process of the sample cannot be effectively solved;

[0005] 2, secondly, the long columnar cell cryopreservation tube is not completely full of sample storage, and sometimes the sample height (labeling) is uneven, which leads to the shaking of the sample during the transportation and storage process, and the leakage may occur when the sample contacts the rubber pad, and the excessive shaking of the sample affects the quality;

[0006] 3, finally, it is limited to one-time use, the general body is plastic, so that the bottom support structure is relatively simple, and it can also be understood as relatively light, when placing (separately), the dumping condition is prone to occur;

[0007] Based on the above defects, a cell cryopreservation tube is proposed. UTILITY MODEL CONTENT

[0008] The utility model aims at solving the defects in the prior art, introduces the double sealing design, makes the sealing performance between the tube body and the cover more reliable, adjusts the space in the tube body storage cavity, reduces the shaking degree of the sample, prevents the sample from contacting the rubber pad due to shaking, combines the external reusable assembly, cooperates with the bottom design of the tube body, and improves the stability effect when placing alone.

[0030] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to relevant references, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items. Example

[0034] like Figure 1-4 As shown, the utility model provides a technical solution: a cell freezing tube, comprising a long cylindrical tube body 1 and a tube cover 2, the tube cover 2 being threadedly connected to the tube body 1, a built-in sealing ring 3 being clamped in the tube cover 2 at a surface corresponding to the open end of the tube body 1, and a scale 11 being provided on the outer side of the tube body 1, which can help users more accurately measure and mark the height of the sample;

[0035] 1) An annular seat 4 is provided on the periphery of the tube body 1 near the open end, and an external sealing ring 5 is provided at the bottom of the tube cover 2;

[0036] 2) A threaded rod 6 extends from the interior of the tube cover 2 into the tube body 1, and an adjusting disk 7 is threadedly connected to the outer periphery of the threaded rod 6;

[0037] 3) The bottom of the tube body 1 is threadedly connected with a counterweight ring 8. Example

[0038] like Figure 1-4 As shown, based on Example 1, this example further provides more detailed designs of cell freezing tubes:

[0039] First, the annular seat 4 and the tube body 1 form an annular groove 41, and when the tube cover 2 is completely threadedly connected to the tube body 1, the sealing effect of the tube cover 2 is enhanced, thereby playing a double sealing role.

[0040] The external sealing ring 5 is clamped in the sealing ring groove 51 annularly opened on the outer side of the threaded opening of the tube cover 2, and the external sealing ring 5 protrudes from the sealing ring groove 51. The design of the external sealing ring 5 enables it to more effectively prevent external contamination and sample leakage. Since it protrudes from the sealing ring groove 51, when the tube cover 2 is tightened, the external sealing ring 5 will be compressed to a certain extent, thereby fitting more tightly on the tube body 1 and between the annular seat 4 and the tube cover 2.

[0041] The length of the threaded rod 6 is half the height of the storage cavity of the tube body 1. Since the sample is generally stored at a height greater than half the height of the storage cavity (except in special circumstances), and even if it is lower than half the height, the adjustment disk 7 rotated to the lowest point can block the sample; the outer diameter of the adjustment disk 7 fits the inner diameter of the storage cavity of the tube body 1, so that it can move up and down inside the tube body 1 to adjust the size of the space in the storage cavity to accommodate samples of different heights.

[0042] In addition, an external threaded column 9 is integrally formed at the bottom of the tube body 1. This external threaded column 9 is used to connect with the counterweight ring 8. The counterweight ring 8 is provided with an internal thread and is made of metal material. It is mounted on the external threaded column 9 through the internal thread. Its main function is to increase the weight of the tube body 1 and improve its stability when placed alone.

[0043] The working process of the utility model is as follows: when using this cell freezing tube, observe the height of the sample in the tube body 1 and adjust the position of the adjustment disk 7 according to the height of the sample to ensure that the sample does not shake in the tube body 1; then tighten the tube cap 2 so that the internal sealing ring 3 and the external sealing ring 5 are tightly fitted on the tube body 1 to form a double sealing barrier;

[0044] It should be noted that the counterweight ring 8 can be installed in advance to increase the stability of the tube body 1 (not necessary if it is placed directly in the storage rack). During the entire process, the counterweight ring 8 plays a role in supporting the tube body 1 to be placed separately.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
