Description

Technical Field

[0001] The utility model relates to the technical field of stem cell culture, in particular to a cell culture centrifuge. Background Art

[0002] During the process of medical research, in order to obtain a certain type of stem cells, medical experimenters usually need to separate human cell solutions, which requires the use of a cell centrifuge. However, when installing cell centrifugation tubes on the centrifuge, only one device can adapt to centrifugation tubes of one size. Centrifugation tubes are usually made of glass. In the case of non - matching, it is easy to lead to low cell centrifugation efficiency, and in severe cases, the centrifugation tubes are prone to being knocked and damaged. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cell culture centrifuge to overcome the above - mentioned defects in the prior art.

[0004] According to a cell culture centrifuge of the utility model, it includes a centrifuge box with an upward opening. A culture test tube is arranged in the centrifuge box. A convex platform and an annular retaining ring are fixedly arranged at the lower end of the centrifuge box. Stable platforms are circumferentially and evenly distributed on the annular retaining ring. A stable spring is connected between the stable platform and the annular retaining ring. The lower end of the culture test tube abuts against the convex platform. Two toothed rings are fixedly arranged on the centrifuge box and are distributed up and down. A rotating frame is slidably connected to each of the two toothed rings. Tooth patterns are arranged on the inner circumferential surface of the toothed ring. A fixing frame is fixedly arranged on each rotating frame. An electromagnet is arranged in the fixing frame. Clamping plates are distributed up and down and staggered at the two fixing frames. A sliding rod is connected between adjacent clamping plates. A rubber pad is arranged at the end of each clamping plate close to the culture test tube. A chute is opened on the fixing frame, and the chute is slidably matched with the sliding rod. The electromagnet is magnetically matched with the sliding rod. Support frames are fixedly arranged at the mutually - remote ends of the two fixing frames. Power motors are fixedly arranged on the two support frames. Rotating rods are power - connected to the lower ends of the two power motors. Two driving wheels are fixedly arranged on the outer circumference of the rotating rod and are distributed up and down. The driving wheel is meshed with the toothed ring. The clamping plate is hollow - arranged, and the sliding rod can slide on the clamping plate.

[0005] The beneficial effects of the utility model are as follows:

[0006] Clamping plates are arranged up and down, which can clamp the circumferential surface of the culture test tube up and down, and thus can adapt to the clamping of culture test tubes with different radii and improve the stability of the culture test tube during rotation. By arranging a rubber pad on the clamping plate to abut against the circumferential surface of the culture test tube, the friction force is increased to prevent the culture test tube from sliding. A stable platform and a convex platform are arranged at the lower part of the centrifuge box, which can prevent the culture test tube from tipping over in the initial state and perform preliminary central positioning, facilitating the centrifugation work.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time: Embodiment

[0018] Reference Figures 1-7 According to an embodiment of the present utility model, a cell culture centrifuge includes a centrifuge box 10 with an upward opening. A culture test tube 11 is arranged inside the centrifuge box 10. A convex platform and an annular retaining ring are fixedly arranged at the lower end of the centrifuge box 10. Stable platforms 24 are circumferentially and evenly distributed on the annular retaining ring. A stable spring is connected between the stable platform 24 and the annular retaining ring. The lower end of the culture test tube 11 abuts against the convex platform. Two toothed rings 12 are fixedly arranged on the centrifuge box 10 and are distributed vertically. A rotating frame 13 is slidably connected to each of the two toothed rings 12. Tooth patterns are arranged on the inner circumferential surface of the toothed ring 12. A fixing frame 14 is fixedly arranged on each rotating frame 13. An electromagnet 19 is arranged inside the fixing frame 14. Clamping plates 22 are vertically and staggeredly distributed at both positions of the two fixing frames 14. A sliding rod 21 is connected between adjacent clamping plates 22. A rubber pad 23 is arranged at the end of each clamping plate 22 close to the culture test tube 11. A sliding groove is formed on the fixing frame 14, and the sliding groove is slidably matched with the sliding rod 21. The electromagnet 19 is magnetically matched with the sliding rod 21. Support frames 15 are fixedly arranged at the mutually remote ends of the two fixing frames 14. A power motor 16 is fixedly arranged on each of the two support frames 15. A rotating rod 17 is power-connected to the lower end of each of the two power motors 16. Two driving wheels 18 are vertically and fixedly arranged on the outer circumference of the rotating rod 17. The driving wheel 18 is engaged with the toothed ring 12. The clamping plate 22 is hollowly arranged, and the sliding rod 21 can slide on the clamping plate 22;

[0019] Open the upper opening of the centrifuge box 10, put the culture test tube 11 into the centrifuge box 10. The lower end of the culture test tube 11 abuts against the stable platform 24 through a semi-circular outer end, so that the stable platform 24 contracts inward against the acting force of the spring. The lower end of the culture test tube 11 abuts against the convex platform at the lower end part of the centrifuge box 10. The circumferential side of the culture test tube 11 abuts against the stable platform 24. The electromagnet 19 at the fixing frame 14 is energized to generate a magnetic force, attracting the sliding rod 21 arranged inside the fixing frame 14 on the same side to slide along the sliding groove on the fixing frame 14. The two adjacent sliding rods 21 on the left and right are mutually remote and approach the corresponding electromagnet 19. The clamping plates 22 on the sliding rod 21 are pulled upward to the left and right. As Figure 5 shown, the rubber pad 23 at the end of the clamping plate 22 close to the culture test tube 11 abuts against the culture test tube 11, clamping the circumferential surface of the culture test tube 11. Control the power motor 16 on the support frame 15 to be energized and work. The power motor 16 drives the rotating rod 17 connected to the lower end to rotate, so that the two driving wheels 18 vertically and fixedly connected to the rotating rod 17 rotate selflessly. The driving wheel 18 is engaged with the toothed ring 12. Under the circumferential sliding fit between the rotating frame 13 and the toothed ring 12, the fixing frames 14 on the left and right rotate circumferentially, thereby driving the clamping plates 22 on the fixing frame 14 and the culture test tube 11 clamped by the clamping plates 22 to rotate, completing the centrifugal rotation work of the culture test tube 11.

[0020] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present utility model. All of them fall within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the appended claims of the present utility model.
