Description

Technical Field

[0001] This utility model relates to the field of cryopreservation tube technology, and in particular to a low-temperature bacterial strain cryopreservation tube. Background Technology

[0002] Cryopreservation tubes are crucial containers for the long-term preservation of microbial strains in microbiology laboratories. They induce dormancy in the strains through a low-temperature environment and maintain their activity through a sealed structure and preservatives. They are widely used in strain preservation, biomedicine, and other fields. To enable traceability of the strains, labels indicating the strain name and freezing date are usually affixed to the surface of the cryopreservation tubes; this is an important auxiliary structure to prevent strain confusion.

[0003] However, the labels on existing cryovials are prone to falling off: condensation generated during the transfer of cryovials between low and room temperature can damage the adhesion of the label adhesive; collisions and friction during handling and transportation, as well as the effects of humidity and volatiles in low-temperature environments, can accelerate the wear and aging of the label, leading to information loss and risks such as difficulty in identifying microorganisms and misuse. Utility Model Content

[0004] In view of the fact that the labels affixed to the surface of the existing cryopreservation tubes for low-temperature microbial strains are prone to falling off or aging due to condensation caused by the transfer between low temperature and room temperature, collisions and friction during handling and transportation, and the influence of humidity and volatiles in the low-temperature environment, resulting in the loss of microbial information and thus causing risks such as difficulty in identification and misuse, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a low-temperature bacterial strain cryopreservation tube, including a cryopreservation tube, a cap is fitted on the upper end of the cryopreservation tube and the cap is threadedly connected to the cryopreservation tube, an installation groove is provided on the top of the cap, a label groove is provided on the bottom wall of the installation groove, a limiting component is provided in the installation groove, and a sealing element is provided between the cryopreservation tube and the cap.

[0006] As a preferred embodiment, the limiting component includes a rotating column, which is fixedly installed on one side of the mounting groove. A transparent plate is rotatably sleeved on the outer side of the rotating column, and the transparent plate is adapted to the mounting groove. A connecting block is connected to the end of the transparent plate away from the rotating column. An arc groove adapted to the connecting block is formed on the inner wall of one side of the mounting groove.

[0007] As a preferred embodiment, the top of the pipe cover is provided with a limiting rod on one side of the mounting groove, and the limiting rod has an inverted U-shaped structure. One end of the limiting rod extends into the arc groove. The top of the connecting block is provided with an insertion hole that matches one end of the limiting rod. The other end of the limiting rod is connected to a counterweight. A cavity is provided inside the pipe cover, and the counterweight is located inside the cavity.

[0008] As a preferred embodiment, a spring piece is provided in the cavity on the side of the limiting rod away from the connecting block. The two ends of the spring piece are fixedly connected to the inner wall of the cavity and the top wall of the counterweight block, respectively. The lower end of the limiting rod near the connecting block is hemispherical, and the front end of the connecting block is provided with a slope.

[0009] As a preferred embodiment, a drive groove is provided on the top of the transparent plate near the connecting block, and a push column is fixedly installed in the drive groove.

[0010] As a preferred embodiment, the sealing element includes a sealing ring, which is equidistantly sleeved on the outer wall of the upper end of the cryopreservation tube. One end of the sealing ring abuts against the inner wall of the tube cap. The sealing ring has an arc-shaped cross-section. A sealing ring is embedded between the top of the inner tube cap and the top of the cryopreservation tube. A suction cup base is provided at the bottom of the cryopreservation tube.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through a limiting component, allows the limiting rod to be pulled upwards, causing the limiting rod to move the counterweight upwards and press the spring sheet until one end of the limiting rod moves out of the insertion hole on the connecting block. Then, the push column can be pushed to move the transparent plate around the rotating column and move it out of the mounting slot. This allows the label paper to be placed into the label slot or removed from the label slot. After the label paper is placed, the transparent plate and connecting block can be reset directly. The inclined surface on one side of the connecting block is used to press and push the hemispherical end of the limiting rod upwards. With the help of the spring sheet and the counterweight, the limiting rod will reset and move downwards, so that one end of the limiting rod is inserted into the insertion hole on the connecting block to restrict and fix it. This can limit, fix and protect the label paper, preventing it from accidentally falling off. It solves the problem that existing cryopreservation tube labels are easily detached or worn and aged due to condensation caused by the transfer of low temperature and room temperature, collision and friction during handling and transportation, and the influence of humidity and volatiles in low temperature environments, resulting in the loss of bacterial information and thus causing difficulties in identification, misuse and other risks.

[0012] 2. This utility model, through the setting of sealing rings and sealing rings, can form a multi-level seal, improving the sealing effect between the cryopreservation tube and the tube cap. The setting of suction cup base makes the cryopreservation tube more stable when placed on the table. Attached Figure Description

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Reference Figure 1 - Figure 4 As shown, a cryopreservation tube for low-temperature bacterial cultures is provided, including a cryopreservation tube 1, a cap 2 fitted onto the upper end of the cryopreservation tube 1, and the cap 2 being threadedly connected to the cryopreservation tube 1. An installation groove 3 is provided on the top of the cap 2, and a label groove 15 is provided on the bottom wall of the installation groove 3. A limiting component is provided in the installation groove 3, and a sealing element is provided between the cryopreservation tube 1 and the cap 2. This provides basic structural support for the installation and fixing of the label and the sealing of the cryopreservation tube 1, ensuring the realization of subsequent functions.

[0017] In this example, the limiting component includes a rotating column 4, which is fixedly installed on one side of the mounting groove 3. A transparent plate 5 is rotatably sleeved on the outside of the rotating column 4, and the transparent plate 5 is adapted to the mounting groove 3. A connecting block 7 is connected to the end of the transparent plate 5 away from the rotating column 4. An arc groove 6 adapted to the connecting block 7 is opened on the inner wall of one side of the mounting groove 3. The rotating column 4 enables the transparent plate 5 to rotate flexibly. The arc groove 6 and the connecting block 7 cooperate to guide the rotation trajectory of the transparent plate 5, ensuring that the transparent plate 5 opens and closes accurately.

[0018] In this example, a limiting rod 8 is provided on the top of the pipe cover 2 on one side of the mounting groove 3, and the limiting rod 8 has an inverted U-shaped structure. One end of the limiting rod 8 extends into the arc groove 6. The top of the connecting block 7 is provided with an insertion hole 16 that matches one end of the limiting rod 8. The other end of the limiting rod 8 is connected to a counterweight 9. A chamber 11 is provided inside the pipe cover 2, and the counterweight 9 is located in the chamber 11. The inverted U-shaped limiting rod 8 facilitates linkage operation, and the counterweight 9 can assist the limiting rod 8 in resetting, ensuring that the limiting rod 8 and the insertion hole 16 are stably matched, thus improving the reliability of the limiting.

[0019] In this example, a spring piece 10 is provided inside the chamber 11 on the side of the limiting rod 8 away from the connecting block 7. The two ends of the spring piece 10 are fixedly connected to the inner wall of the chamber 11 and the top wall of the counterweight block 9, respectively. The lower end of the limiting rod 8 near the connecting block 7 is hemispherical, and the front end of the connecting block 7 is provided with a slope. The spring piece 10 provides elastic restoring force, which, together with the hemispherical end of the limiting rod 8 and the slope of the connecting block 7, realizes automatic limiting when the transparent plate 5 is reset, without the need for manual alignment, making the operation more convenient.

[0020] In this example, a drive groove 12 is provided on the top of the transparent plate 5 near the connecting block 7, and a push post 13 is fixedly installed in the drive groove 12; the push post 13 provides a force point for the rotation of the transparent plate 5, and the drive groove 12 can prevent the hand from slipping during operation and improve the convenience of opening and closing operation.

[0021] In this example, the sealing element includes a sealing ring 14, which is equidistantly fitted onto the upper outer wall of the cryopreservation tube 1. One end of the sealing ring 14 abuts against the inner wall of the tube cap 2. The sealing ring 14 has an arc-shaped cross-section. A sealing ring is embedded between the top of the inner tube cap 2 and the top of the cryopreservation tube 1. A suction cup base is provided at the bottom of the cryopreservation tube 1. The arc-shaped sealing ring 14 and the sealing ring form a multi-level seal, which significantly enhances the sealing performance of the cryopreservation tube 1. The suction cup base can improve the stability of the cryopreservation tube 1 when it is placed and prevent accidental tipping.

[0022] During use, the label installation and fixing principle is as follows: When a label needs to be placed, pull up the limiting rod 8 to move the counterweight 9 upward and squeeze the spring piece 10 until one end of the limiting rod 8 disengages from the insertion hole 16 of the connecting block 7; push the push column 13 to drive the transparent plate 5 to rotate around the rotating column 4 and open it. After placing the label paper with the information written on it into the label slot 15, rotate the transparent plate 5 in the opposite direction to reset the connecting block 7 along the arc groove 6. The inclined surface at the front end of the connecting block 7 will squeeze the hemispherical end of the limiting rod 8 to move it upward. When the connecting block 7 is fully reset, the elastic restoring force of the spring piece 10 and the gravity of the counterweight 9 work together to push the limiting rod 8 downward and insert it into the insertion hole 16, completing the locking of the transparent plate 5 and realizing the sealing and fixing of the label paper and physical protection.

[0023] Sealing principle: When the cryopreservation tube 1 and the tube cap 2 are connected by threads, the inner wall of the tube cap 2 will closely contact the arc-shaped sealing ring 14 on the outer wall of the cryopreservation tube 1. At the same time, the sealing ring between the top of the inner tube cap 2 and the top of the cryopreservation tube 1 will be squeezed and deformed. The elastic deformation of the arc-shaped sealing ring 14 and the dual action of the sealing ring form a multi-level sealing barrier, which effectively prevents external air, moisture and pollutants from entering the interior of the cryopreservation tube 1, and at the same time prevents the volatilization and leakage of the cryoprotectant or bacteria inside the tube.
