Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a deep cryogenic sample transfer box. Background Technology

[0002] Deep cryopreservation refers to the preservation of biological samples in an extremely low temperature environment. For samples that are difficult to obtain, deep cryopreservation can achieve long-term preservation. At deep low temperatures, deep cryopreservation samples have extremely important applications in many fields such as biomedical research, clinical treatment and biobank construction. The structure of cells and tissues can be well maintained, reducing degradation and damage. In order to avoid damage to samples due to sudden temperature changes and for convenient storage, a transfer box is used for cooling storage.

[0003] The main structure of a cryogenic sample transfer box includes an outer shell, an inner liner, a refrigeration system, and sample racks. It monitors the temperature inside the box while facilitating the placement of cryogenically frozen samples. Placing these samples in the cryogenic sample transfer box ensures their continued usability in subsequent research. During use, samples are placed in sample racks fixed to the inner wall. If the racks do not fit snugly during transport, they can easily shake and damage the samples. Existing transfer boxes use standardized storage containers and corresponding fixed sample racks to secure samples, but the internal structure of the sample racks cannot be modularly adjusted. This results in a lack of flexibility in adjusting storage space according to the size and quantity of user samples, making it unsuitable for different types of samples and increasing the risk of sample contact and cross-contamination.

Connecting support rod 12 is fixed to the upper middle side of each of the two adjusting brackets 1-8. Connecting support rod 12 not only enhances structural stability but also connects to the other end of the electric push rod 14. The electric push rod 14 provides precise control, making the entire system more intelligent and automated. When the electric push rod 14 starts, it expands inwards and outwards, pushing and pulling connecting support rod 1-12 and connecting support rod 2-13 to move upwards and downwards, achieving the purpose of structural adjustment. The outer wall of pulley 2-11 slides to the fixed frame 15. The fixed frame 15 facilitates the installation and fixation of the push plate 16. The bottom of the fixed frame 15 is rotatably connected to the bottom of the outer wall of adjusting bracket 2-10, further enhancing structural stability. Push plate 1... The internal space structure of the push plate 16 can be easily modified to achieve modularity. A movable plate 17 is set on the front side of the outer wall of the push plate 16. The movable plate 17 is to provide more operating space and fixed support rod 6, so that users can operate more flexibly. The left and right sides of the outer wall of the movable plate 17 are rotatably connected to two telescopic frames 18. The telescopic frames 18 optimize the adjustment structure and improve the extensibility of the structure, making the whole system more flexible and adaptable. The adjacent side of the outer wall of the telescopic frame 18 is rotatably connected to a fixed plate 19.

The adjacent sides of the push plate 16 and the movable plate 17 are fixed with buffer pads 20. The buffer pads 20 reduce impact and vibration during operation and protect the internal components from damage.

[0035] A fixing block 201 is fixed to the bottom of the outer wall of the movable plate 17 for connecting the top structure. Two sliding plates 202 are slidably connected to the left and right sides of the bottom of the fixing block 201, which can pop out the sliding plates 202 and maintain the internal temperature stability, so as to quickly remove the sample. Sliding grooves 204 are opened on the left and right sides of the inner wall of each sliding plate 202, so that the structure can quickly pop out and slide out and remain fixed to the fixed shell 209. Limiting posts 203 are installed through the front side of the inner wall of the two sliding grooves 204. The upper and lower ends of the limiting posts 203 are fixedly connected to the front end of the inner wall of the fixed shell 209 to prevent the structure from popping out loosely, enhance the connection of the structure and prevent derailment. A moving groove 210 is opened on the front side of the inner wall of each fixed shell 209. The moving groove 210 facilitates the adjustment of the inner wall space of the mechanism and optimizes the sliding of the internal structure. A positioning block 211 is fixedly connected to the rear side of the inner wall of the moving groove 210. A limiting groove 212 is opened in the middle of the inner wall of the positioning block 211. The positioning groove and connecting rod 206 restrict the structure. The length of the connecting rod 206 is used to control the excessive extension of the slide. The other end of the connecting rod 206 is slidably connected to the inner wall of the limiting groove 212, realizing convenient and efficient sliding. Two tension springs 207 are fixedly connected to the left and right sides of the outer wall of the slide plate 202. The tension springs 207 can not only correct the structure to its original position, but also make the structure's extension and contraction smoother. Pressing the slide plate 202 pushes the tension springs 207, and the tension springs 207 push out the structure, realizing quick sample removal. The other ends of the two tension springs 207 are fixedly connected to the second fixing block 208. The adjacent sides of the two second fixing blocks 208 are fixedly connected to the fixing shell 209, maintaining the structural connection of the tension springs 207, enhancing the overall flexibility, ensuring the stability and accuracy of the moving plate 17 during the movement, and effectively controlling the movement range and direction of the moving plate 17, thereby realizing precise operation and control.
