[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a culture device for cell separation, including a culture chamber 1, four sides of the bottom end of the culture chamber 1 are fixedly connected with feet 2, a driving motor 4 is fixedly connected to the inner bottom wall of the culture chamber 1, the driving end of the driving motor 4 is fixedly connected to the outer bottom wall of the rotating plate 6, a sealing cover 3 is rotatably connected to the outer wall of the top end of the culture chamber 1, and the bottom ends of the connecting frames 7 are respectively fixedly connected to the outer walls of the four sides of the top end of the rotating plate 6.

[0031] Specifically: when the inner driving motor 4 of the culture chamber 1 is started, the motor 4 drives the transmission gear 18 connected thereto to rotate along the gear ring 5 through the gear ring 5 driven by it. This rotation enables the movement of the gear ring 5 to be transmitted, thereby driving the operation of related mechanical devices. At the same time, the feet 2 play an important role in this process. It can effectively buffer the vibration generated by the centrifugal force and ensure the stability of the culture chamber 1. When the sealing cover 3 is covered on the opening of the culture chamber 1, it can ensure the tightness inside the culture chamber 1, thereby maintaining the closed state of its internal environment. The closed environment is beneficial to generating conditions such as temperature and humidity during the culture process.

[0032] Referring to Figure 3 and Figure 4 , the connecting frame 7, deflection platforms 8 are rotatably connected to the top ends of the connecting frame 7, conveyor wheels 15 are fixedly connected to the outer bottom walls of the gear rods 17 and the deflection platforms 8, the conveyor wheels 15 are connected by a conveyor belt 16, rotating rods 9 are rotatably connected to the inner walls of the top ends of the deflection platforms 8, transmission gears 18 are fixedly connected to the bottom ends of the deflection platforms 8, a gear ring 5 is fixedly connected to the inner bottom wall of the culture chamber 1, the gear ring 5 and the transmission gear 18 are meshed, spherical gaskets 19 are fixedly connected to both the upper and lower ends of the rod body of the rotating rod 9, and gear pieces 20 are fixedly connected to the outer wall of the rotating rod 9 corresponding to the opposite ends of the spherical gaskets 19, and the gear pieces 20 and the gear rods 17 are meshed.

[0033] Specifically: When the transmission gear 18 starts to rotate, it drives the deflection table 8 to rotate. The rotation of the deflection table 8 transmits the motion to the gear rod 17 through the connected conveyor wheels 15 and conveyor belt 16, causing the gear rod 17 to rotate accordingly. At the same time, the rotation of the deflection table 8 makes the spherical gasket 19 on the rotating rod 9 move along an arc trajectory within the arc groove ring 10. During the synchronous rotation of the gear rod 17, it deflects through the gear piece 20, thereby driving the rotating rod 9. The movement of the rotating rod 9 causes the test tube on the fixed frame 11 to deflect. At the same time, the rotation of the rotating plate 6 makes the test tube perform a circular motion. With the combination of deflection and circular rotation, the test tube can generate a higher centrifugal force, which is of great significance for the material mixing and separation process in the culture chamber 1. Through this comprehensive movement, the test tube can obtain a more uniform centrifugal force effect within the culture chamber 1, thereby improving the culture effect and experimental accuracy.

[0034] Refer to Figure 5 and Figure 6 , the fixed frame 11, a threaded ring 12 is fixedly connected to the top of the fixed frame 11, an adjusting ring 21 is threadedly connected to the outer wall of the threaded ring 12, the bottom end of the adapter ring 22 is rotatably connected to the top end of the adjusting ring 21, fixing plates 13 are fixedly connected to the four sides of the outer wall of the fixed frame 11, retractable plates 24 are rotatably connected to the four sides of the outer wall of the top end of the adapter ring 22, rotating blocks 25 are rotatably connected to the opposite ends of the retractable plates 24, the opposite ends of the rotating blocks 25 are rotatably connected to the inner walls of the opposite ends of the fixing plates 13, traction plates 23 are rotatably connected to the top ends of the rotating blocks 25, and the bottom ends of the clamping claws 14 are rotatably connected to the top ends of the traction plates 23.

[0035] Specifically: When clamping a test tube filled with solution, first rotate the adjusting ring 21 to make it move along the threaded ring 12. The rotation action of the adjusting ring 21 is transmitted through the adapter ring 22, further driving the movement of the retractable plate 24. The movement of the retractable plate 24 causes the rotating block 25 to contract, so that the traction plate 23 also moves accordingly. The movement of the traction plate 23 makes the clamping claws 14 clamp the test tube. The rotation amplitude of the adjusting ring 21 directly affects the clamping force of the clamping claws 14. By rotating the adjusting ring 21, the opening and closing degree of the clamping claws 14 can be precisely controlled. This adjustment function enables the clamping claws 14 to adapt to test tubes of different diameters. Regardless of the size of the test tube, the clamping force of the clamping claws 14 can be adjusted to achieve a stable clamping, thereby ensuring the safety and stability of the test tube during the operation process.

[0036] Working principle: When the drive motor 4 in the culture chamber 1 starts, the drive motor 4 drives the gear ring 5 to make the transmission gear 18 connected thereto rotate along the gear ring 5. The tripod 2 can buffer the vibration caused by the centrifugal force generated in the culture chamber 1. When the sealing cover 3 is covered on the culture chamber 1, the culture chamber 1 can be kept airtight. When the transmission gear 18 rotates, the transmission gear 18 drives the deflection table 8 to rotate. When the deflection table 8 rotates, the conveyor wheel 15 connected thereto drives the gear rod 17 to rotate through the conveyor belt 16. When the deflection table 8 rotates, the spherical gasket 19 at the rotating rod 9 rotates along the arc groove ring 10. When the gear rod 17 rotates synchronously, the gear rod 17 deflects through the gear piece 20, so that the rotating rod 9 drives the test tube connected to the fixed frame 11 to deflect and rotate in a circular motion under the rotation of the rotating plate 6. Thus, the test tube rotates in a circular motion while deflecting, thereby increasing the centrifugal force of the test tube in the culture chamber 1. When clamping the test tube filled with solution, rotate the adjusting ring 21 to make it move along the threaded ring 12, so that the adjusting ring 21 drives the contraction plate 24 through the adapter ring 22 to contract the traction plate 23 by the rotating block 25. The traction plate 23 drives the clamping jaw 14 to clamp the test tube, and the adjusting ring 21 adjusts the clamping force of the clamping jaw 14 through the moving amplitude, so as to facilitate clamping test tubes with different diameters.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
