Technical Field

[0001] This application relates to the technical field of microbial strain preservation, and in particular to a microbial strain preservation device. Background Technology

[0002] A microbial strain refers to a pure-cultured cell or cell population isolated from a microorganism. Microbial strains have a wide range of applications, including environmental protection, medicine and health, food industry, and agriculture. For example, in environmental protection, microbial strains can be used to degrade pollutants; in medicine and health, they can be used to manufacture drugs or treat diseases; and in the food industry, they can be used to ferment foods or produce biopesticides. Cryopreservation of microbial strains is a commonly used biotechnology that can effectively protect and preserve microbial strains for long-term research and application.

[0003] Currently, in order to ensure that microbial strains remain in a relatively stable state over a long period of time, they are generally stored in freezers.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: During the placement and removal of strains, due to the low temperature inside the freezer, when handling strains located at the innermost part of the freezer, tools or gloves are required to prevent frostbite to the operator's hands. Therefore, handling strains near the innermost part of the freezer is inconvenient. To address this, we propose a microbial strain preservation device. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a microbial strain preservation device. For example... Figures 1-3 As shown, it includes a freezer 1, a door 2 on the freezer 1, and a fixed base 3 installed inside the freezer 1. A support plate 4 is provided at the end of the fixed base 3. Multiple test tube racks 5 are fixedly connected to the support plate 4. A connecting shaft 6 is fixedly connected to the bottom end of the support plate.

[0028] Also includes:

[0029] The movable component 7 is installed inside the freezer 1 and connected to the connecting shaft 6. The movable component 7 is used to drive the support plate 4 to move so that part of the test tube rack 5 is located outside the freezer 1.

[0030] The rotating component 8 is configured to cooperate with the moving component 7 and is connected to the connecting shaft 6. The rotating component is used to drive the connecting shaft 6 to rotate, thereby causing the support plate 4 to rotate accordingly. Through the cooperation of the moving component 7 and the rotating component 8, the support plate 4 can be moved to a part outside the freezer 1, and at the same time, the support plate 4 can be rotated, which facilitates the handling of bacterial strains.

[0031] Please see Figure 3 and Figure 4 The movable component 7 shown in the figure includes a connecting frame 9 rotatably connected to the connecting shaft 6. A threaded block 10 is fixedly connected to the connecting frame 9. A threaded rod 11 is threadedly connected to the threaded block 10. A driving member 12 is installed at one end of the threaded rod 11, and a rotating shaft 28 rotatably connected to the fixed seat 3 is fixedly connected to the other end of the threaded rod 11. An elastic member 13 for resetting the threaded block 10 is installed on the rotating shaft 28. Through the cooperation of the threaded rod 11 and the threaded block 10, the threaded block 10 drives the connecting frame 9 to move, thereby causing the connecting shaft 6 to drive the support plate 4 to move.

[0032] Please see Figures 3-5 The rotating assembly 8 shown in the figure includes a first bevel gear 14 fixedly connected to the connecting shaft 6. A second bevel gear 15, sleeved on the outside of the threaded rod 11, meshes with the outer side of the first bevel gear 14. A rotating sleeve 16, sleeved on the outer side of the threaded rod 11, is fixedly connected to the axis of the second bevel gear 15. The rotating sleeve 16 is rotatably connected to the connecting frame 9, and a sliding block 17, slidably connected to the threaded rod 11, is fixedly connected to the rotating sleeve 16. A sliding groove 18, adapted to the sliding block 17, is provided on the threaded rod 11. By providing the sliding block 17 on the rotating sleeve 16 and the sliding groove 18 on the threaded rod 11, the rotation of the threaded rod 11 causes the sliding block 17 to drive the rotating sleeve 16 to rotate, thereby enabling the second bevel gear 15 to drive the first bevel gear 14 to rotate. Through the action of the connecting frame 9, the first bevel gear 14 and the second bevel gear 15 are always meshed.

[0033] Please see Figure 3 and Figure 4 The driving component 12 shown in the figure includes a motor 19 fixedly connected to the fixed base 3. The output end of the motor 19 is fixedly connected to a drive shaft 20. The drive shaft 20 is fixedly connected to the threaded rod 11. The motor 19 is a forward and reverse motor 19, which enables the threaded rod 11 to rotate forward and backward, thereby enabling the support plate 4 to move back and forth.

[0034] Please see Figure 3 and Figure 4The elastic element 13 shown in the figure includes a fixed plate 21 fixed to the outside of the rotating shaft 28. A spring 22 sleeved on the outside of the rotating shaft 28 is fixedly connected to the fixed plate 21. A movable plate 23 sleeved on the outside of the rotating shaft 28 is fixedly connected to the end of the spring 22. The movable plate 23 is installed at the connection between the rotating shaft 28 and the threaded rod 11. The action of the spring 22 allows the threaded block 10 to always fit against the threaded rod 11. Thus, when the threaded rod 11 reverses, the threaded block 10 can once again establish a threaded connection with the threaded rod 111, causing the threaded block 10 to move in the opposite direction and reset.

[0035] Please see Figure 1 and Figure 2 As shown in the figure, support legs 24 are installed at the bottom corners of the freezer 1. The support legs 24 can improve the stability of the device. In addition, the support legs 24 in this solution can be adjusted in height, thereby further improving the stability of the device.

[0036] Please see Figure 2 and Figure 3 As shown in the figure, a sealing strip 25 is installed on the inner side of the cabinet door 2, and a handle 26 is fixedly connected to the outer side of the cabinet door 2. The sealing strip 25 can improve the sealing performance of the freezer 1, and the handle 26 makes it easy to open the cabinet door 2.

[0037] Please see Figure 2 and Figure 3 The test tube rack 5 shown in the figure has a sponge sleeve 27 installed inside. When placing the test tube, the sponge sleeve 27 can squeeze the test tube to stabilize it in the test tube rack 5, thus preventing the test tube from being damaged and causing the strain to leak.

[0038] The implementation principle of the microbial strain preservation device in this application embodiment is as follows: During the process of taking out and putting out microbial strains, the door 2 is opened by the handle 26. At this time, the opening of the door 2 causes the motor 19 to start. The starting of the motor 19 drives the drive shaft 20 to rotate, and the rotation of the drive shaft 20 causes the threaded rod 11 to rotate. The rotation of the threaded rod 11 causes the threaded block 10 to move the connecting frame 9. The movement of the connecting frame 9 causes the connecting shaft 6 to move, and the movement of the connecting shaft 6 causes the support plate 4 to move. After the support plate 4 moves, part of the test tube rack 5 will be located on the outside of the freezer 1, which facilitates the taking out and putting out of microbial strains. During this process, the continuous starting of the motor 19 causes the threaded rod 11 to rotate continuously, which will cause the threaded block 10 to disengage from the threaded rod 11. After the threaded block 10 disengages from the threaded rod 11, the threaded block 10 no longer drives the connecting frame 9 to move, and the movement of the support plate 4 stops. However, due to the presence of the movable piece 23 and the spring 22, the threaded block 10 will always be in contact with the threaded rod 11.

[0039] In the above process, the rotation of the threaded rod 11 will cause the rotating sleeve 16 to rotate through the sliding groove 18 and the sliding block 17, which in turn causes the second bevel gear 15 to rotate, which in turn causes the first bevel gear 14 to rotate, which in turn causes the connecting shaft 6 to rotate, which in turn causes the support plate 4 to rotate, and the rotation of the support plate 4 causes the test tube rack 5 located inside the freezer 1 to rotate to the outside of the freezer 1, which makes it easier to take out and put in microbial strains;

[0040] After the pick-up and drop-off are completed, the control motor 19 reverses. Due to the action of the spring 22, the threaded block 10 is made to fit the threaded rod 11. As the motor 19 reverses and the threaded rod 11 reverses, the threaded block 10 will move in the opposite direction, which will cause the connecting frame 9 to drive the connecting shaft 6 to move in the opposite direction, and then drive the support plate to move in the opposite direction and reset.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
