Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment technology, and more specifically to a lever-sealed cryopreservation tube holder. Background Technology

[0002] In experimental fields such as biomedicine and molecular biology, it is often necessary to cryopreserve biological samples, and cryovials are commonly used containers for storing these samples. To facilitate management and retrieval, cryovials are usually placed on cryovial stands.

[0003] Traditional cryopreservation tube caps mostly use a simple screw-on method, relying on screw caps or compression caps for sealing. In low-temperature environments, the seal is easily compromised due to thermal expansion and contraction. Existing cryopreservation tube holders only provide storage functions and cannot assist in sealing, resulting in poor sealing of cryopreservation tubes. This can easily lead to sample contamination or moisture loss, affecting sample quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing cryopreservation tube holders only provide storage functions and cannot assist in sealing, resulting in poor sealing of cryopreservation tubes, which easily leads to sample contamination or moisture loss and affects sample quality. Therefore, this invention provides a lever-sealed cryopreservation tube holder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lever-sealed cryopreservation tube support has side plates on both sides of the top of the base. A placement rack and a partition are arranged sequentially from top to bottom between the two side plates. The placement rack and the partition are provided with a number of evenly distributed through holes. The top of the placement rack is provided with a lever sealing mechanism that corresponds to each through hole to improve the sealing performance of the cryopreservation tube.

[0007] As a further description of the above technical solution, the lever sealing mechanism includes an L-shaped fixing seat fixedly connected to the top of the placement plate, a U-shaped block fixedly connected to one side of the L-shaped fixing seat, a pressure rod rotatably connected to the U-shaped block via a rotating shaft, a handle fixedly connected to the top of the pressure rod, a pressure head fixedly connected to one end of the pressure rod, a sealing gasket fixedly connected to the inner top wall of the pressure head, and a limit component provided on one side of the L-shaped fixing seat at the bottom of the pressure rod.

[0008] As a further description of the above technical solution, the limiting component includes a spring fixedly connected to one side of the L-shaped fixing seat, one end of the spring being fixedly connected to a limiting block, and the outer end of the limiting block being rounded.

[0009] As a further description of the above technical solution, the rotating shaft is a damping rotating shaft, and the pressure rod and the placement plate form a 60° angle in the initial state.

[0010] As a further description of the above technical solution, the shape of the pressure head is adapted to the outer contour of the cryopreservation tube cap, and its bottom surface is a concave curved surface structure corresponding to the shape of the top of the cryopreservation tube cap.

[0011] As a further description of the above technical solution, a blind hole is provided on the base at the position corresponding to the through hole.

[0012] As a further description of the above technical solution, the diameter of the through hole is larger than the outer diameter of the cryopreservation tube, and three evenly distributed anti-slip ribs are provided on the inner wall of the through hole, with rounded corners at both ends of the anti-slip ribs.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a lever sealing mechanism to press the pressure head against the cryovial cap, ensuring a tight seal between the sealing gasket and the cap. This effectively improves the sealing performance of the cryovial, preventing sample contamination and moisture loss, thus guaranteeing sample quality. Furthermore, the shape design of the pressure head and cap, combined with various cap types, allows for compatibility with different types of cryovials, significantly enhancing sealing adaptability and effectiveness. Simultaneously, it provides stability and fixation for the cryovial, preventing it from shaking or falling off the support, ensuring cryovial safety and improving the device's practicality.

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0022] This utility model provides a lever-sealed cryopreservation tube support. Please refer to [reference needed]. Figures 1-5 As shown, the base 1 has side plates 2 on both sides of the top. Between the two side plates 2, from top to bottom, there are placement racks 3 and partitions 4. The placement racks 3 and partitions 4 are provided with several evenly distributed through holes 6. The top of the placement racks 3 is provided with lever sealing mechanisms 5 that correspond one-to-one with the through holes 6 to improve the sealing of the cryopreservation tubes.

[0023] The lever sealing mechanism 5 includes an L-shaped fixing seat 51 fixedly connected to the top of the placement rack 3. A U-shaped block 52 is fixedly connected to one side of the L-shaped fixing seat 51. A pressure rod 53 is rotatably connected to the U-shaped block 52 via a rotating shaft 54. The pressure rod 53 forms a 60° angle with the placement rack 3 in the initial state. The rotating shaft 54 ​​is a damping rotating shaft. A handle 55 is fixedly connected to the top of the pressure rod 53. A pressure head 56 is fixedly connected to one end of the pressure rod 53. A sealing gasket 57 is fixedly connected to the inner top wall of the pressure head 56. A limit component is provided on one side of the L-shaped fixing seat 51 at the bottom of the pressure rod 53. The limit component includes a spring 58 fixedly connected to one side of the L-shaped fixing seat 51. A limit block 59 is fixedly connected to one end of the spring 58. The outer end of the limit block 59 is rounded.

[0024] In this embodiment of the application, the device is placed on the experimental table to be used. In the initial state, the pressure rod 53 is at a 60° angle with the placement rack 3, and the pressure head 56 is away from the upper part of the cryopreservation tube through hole 6, leaving space for the insertion of the cryopreservation tube. The movable pressure head 56 on the outer side of the vertical part of the L-shaped fixing seat 51 is located below the initial position of the pressure rod 53 by the action of the spring 58, preventing the pressure rod 53 from rotating downward due to its own weight. At the same time, the rotating shaft 54 ​​helps to maintain the stability of the pressure rod 53. At this time, the cryopreservation tube containing the biological sample is vertically inserted into the through hole 6 of the placement rack 3. Continue to insert it until it passes through the through hole 6 of the partition 4 until it is inserted into the blind hole 7. Depending on the type of cryopreservation tube cap, such as a knob cap, a press cap, or a snap cap, it is tightly sealed on the cryopreservation tube opening. A sealing gasket 57 of appropriate shape is selected according to the structure of the cryopreservation tube cap, and it is fixed to the concave curved surface at the bottom of the pressure plate using medical grade double-sided tape.

[0025] The operator grips the handle 55 with anti-slip texture in the middle of the pressure rod 53 and presses it downwards. Using the hinge point between the pressure rod 53 and the U-shaped block 52 as the fulcrum, the force generated by the rotation of the pressure rod 53 is greater than the elastic force of the spring 58 between the limiting block 59 and the L-shaped fixing seat 51. The limiting block 59 is squeezed back and no longer obstructs the rotation of the pressure rod 53. The pressure rod 53 rotates around the rotating shaft 54, driving the pressure head 56 to move downwards. Since the shape of the pressure head 56 matches the outer contour of the cryopreservation tube cap, its concave bottom surface fits against the top of the cryopreservation tube cap, so that the sealing gasket 57 is tightly pressed on the cryopreservation tube cap, forming an effective sealing structure to prevent outside air and moisture from entering. Insert the cryovial to prevent sample contamination and moisture loss. After the sealing gasket 57 on the pressure head 56 is tightly fitted with the cryovial cap, the limiting block 59 extends under the rebound force of the spring 58 to block the pressure rod 53 and fix the pressure rod 53 in place. This allows the pressure head 56 to continuously apply pressure to the cryovial cap, ensuring not only a sealing effect but also a firm fixation of the cryovial, preventing it from shaking or falling off the support, further ensuring the safety of the cryovial. When it is necessary to remove the cryovial, the operator lifts the pressure rod 53 upwards, causing it to return to its initial 60° angle. The pressure head 56 then separates from the cryovial cap, allowing the cryovial to be easily removed vertically upwards.

[0026] Furthermore, the shape of the pressure head 56 is adapted to the outer contour of the cryopreservation tube cap, and its bottom surface is a concave curved surface structure corresponding to the shape of the top of the cryopreservation tube cap. When in use, the pressure head 56 is designed to be detachable, and the appropriate pressure head 56 can be replaced according to the diameter of the cryopreservation tube cap for convenient use.

[0027] Furthermore, a blind hole 7 is provided on the base 1 at the position corresponding to the through hole 6. During use, the stability of the cryopreservation tube is further ensured by using the blind hole 7.

[0028] Furthermore, the diameter of the through hole 6 is larger than the outer diameter of the cryopreservation tube. Three evenly distributed anti-slip ribs 8 are provided on the inner wall of the through hole 6. Both ends of the anti-slip ribs 8 are rounded. When in use, the diameter of the through hole 6 is larger than the outer diameter of the cryopreservation tube, which facilitates the insertion of the cryopreservation tube. The anti-slip ribs 8 make the insertion and placement of the cryopreservation tube more stable, effectively preventing it from shaking, and also facilitating the subsequent sealing operation of the cryopreservation tube cap.

[0029] The working principle of the utility model is as follows: During use, the operator holds the handle 55 and presses it downwards. Using the hinge point between the pressure rod 53 and the U-shaped block 52 as the fulcrum, the limiting block 59 is squeezed back, no longer obstructing the rotation of the pressure rod 53. The pressure rod 53 rotates around the rotating shaft 54, causing the pressure head 56 to move downwards, so that the sealing gasket 57 is tightly pressed against the cryovial cap, forming an effective sealing structure. This prevents external air and moisture from entering the cryovial, preventing sample contamination and moisture loss. When the sealing gasket 57 on the pressure head 56 is tightly pressed against the cryovial cap... After the tube is attached, the limiting block 59 extends under the rebound force of the spring 58 to block the pressure rod 53 and fix the pressure rod 53 in place. This allows the pressure head 56 to continuously apply pressure to the cryopreservation tube cap, ensuring not only a sealing effect but also a firm fixation of the cryopreservation tube, preventing it from shaking or falling off the support and further ensuring the safety of the cryopreservation tube. When it is necessary to remove the cryopreservation tube, the operator lifts the pressure rod 53 upwards, causing the pressure rod 53 to return to its initial 60° angle. The pressure head 56 then separates from the cryopreservation tube cap, allowing the cryopreservation tube to be easily removed vertically upwards.

[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
