The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0019] Please refer to Figures 1 to 4 , wherein, Figure 1 is a schematic structural diagram of the centrifuge of the present invention, Figure 2 is a top view of the centrifuge of the present invention, Figure 3 is a side view of the centrifuge of the present invention, Figure 4 is the Figure 3 structural cross - section along line A - A of the present invention.

[0020] The present invention provides a centrifuge, including a rotating mechanism, a connecting plate 11, a threaded rod 12, a handle 13 and a fixed plate 14. The rotating mechanism includes a top plate 1, a connecting column 2, a limiting piece 3, a fixed shell 4, a bottom plate 5, four fixing components and a driving component. Each of the fixing components includes a fixed block 6 and two rotating columns 7. The driving component includes a motor 8, a first gear 9 and a second gear 10. Through the foregoing solution, the problem that the existing centrifuge has a very cumbersome structure, is not convenient to move, and the process of installing test tubes is very troublesome, affecting the detection efficiency, is solved.

[0021] For this specific embodiment, the connecting column 2 is fixedly connected to the top plate 1 and is located below the top plate 1. The limiting piece 3 is fixedly connected to the connecting column 2 and is located below the connecting column 2. The bottom plate 5 is arranged below the limiting piece 3. The fixed shell 4 is fixedly connected to the bottom plate 5 and covers the outside of the limiting piece 3. Four openings 16 are arranged on the outside of the top plate 1. The driving component is arranged on one side of the connecting column 2. The four fixing components are arranged inside the corresponding openings 16. Test tubes are respectively placed inside the four fixing components. Driven by the driving component, the connecting column rotates accordingly. Under the action of centrifugal force, solid particles accumulate at the bottom of the test tube. The fixed shell 4 fixes the position of the limiting piece 3. When the weights of the test tubes fixed on the four fixing components are different, the fixed shell 4 prevents the connecting column 2 from tilting, so that the top plate 1 is always in a horizontal state. The operation of the present invention is simple, and four different test tubes can be detected simultaneously.

[0022] Among them, the fixed block 6 is arranged outside the opening 16. One end of each of the two rotating columns 7 is fixedly connected to the fixed block 6, and the other end of each of the two rotating columns 7 is rotatably connected to the top plate 1. An installation hole 17 is arranged on the surface of the fixed block 6. A test tube is installed inside the installation hole 17, and the test tube mouth is stuck above the fixed block 6. When the driving assembly drives the connecting column 2 to rotate, under the action of centrifugal force, the test tube tilts accordingly, presenting a posture with the head facing inward and the tail facing outward. At the same time, under the action of centrifugal force, solid particles move towards the tail of the test tube. After centrifugation is completed, the connecting column 2 stops slowly. Under the action of gravity, the tail of the test tube moves downward to prevent the internal liquid from flowing out.

[0023] Secondly, the motor 8 is fixedly connected to the bottom plate 5 and is located on one side of the fixed shell 4. The first gear 9 is fixedly connected to the connecting column 2. The second gear 10 is fixedly connected to the output end of the motor 8. The first gear 9 and the second gear 10 are meshed. The motor 8 drives the second gear 10 to rotate, and the second gear 10 drives the first gear 9 to rotate. The limiting piece 3 is stuck inside the handle of the fixed shell 4. When rotating, the fixed shell 4 restricts the position and direction of the connecting column 2, improving the stability of the connecting column 2 and the top plate 1 during rotation.

[0024] Then, the connecting plate 11 is fixedly connected to the bottom plate 5 and is located below the bottom plate 5. The connecting plate 11 is arranged in an L shape. The fixing plate 14 is arranged between the bottom plate 5 and the connecting plate 11. One end of the threaded rod 12 is rotatably connected to the fixing plate 14. The other end of the threaded rod 12 is threadedly connected to the connecting plate 11 and passes through the connecting plate 11. The handle 13 is fixedly connected to the threaded rod 12 and is located below the threaded rod 12. The bottom plate 5 and the connecting plate 11 are fixed to the outside of the table board. By rotating the handle 13, the threaded rod 12 moves, and the threaded rod 12 pushes the fixing plate 14. The fixing plate 14 is adapted to the connecting plate 11, so that the fixing plate 14 can only move along the connecting plate 11. With the cooperation of the fixing plate 14 and the bottom plate 5, the table board is clamped, facilitating the installation or movement of the present utility model and improving the practicability.

[0025] In addition, a clamping block 15 is arranged at one end of the threaded rod 12. The clamping block 15 is arranged inside the fixing plate 14. The clamping block 15 is circularly arranged. The clamping block 15 is stuck inside the fixing plate 14. When the threaded rod 12 rotates, the clamping block 15 will drive the fixing plate 14 to move accordingly.

[0026] When using the present utility model, the bottom plate 5 and the connecting plate 11 are fixed on the outer side of the tabletop. Rotate the handle 13, and the threaded rod 12 moves. The threaded rod 12 pushes the fixing plate 14. With the cooperation of the fixing plate 14 and the bottom plate 5, the tabletop is clamped. Install the test tube inside the installation hole 17, and the test tube mouth is stuck above the fixing block 6. The fixed shell 4 fixes the position of the limiting piece 3. When the weights of the test tubes fixed on the four fixing components are different, the fixed shell 4 prevents the connecting column 2 from being washed, so that the top plate 1 is always in a horizontal state. The motor 8 drives the second gear 10 to rotate, and the second gear 10 drives the first gear 9 to rotate, so that the connecting column 2 rotates accordingly. Under the action of centrifugal force, the test tube tilts accordingly, presenting a posture with the head facing inwards and the tail facing outwards. At the same time, under the action of centrifugal force, the solid particles move towards the tail of the test tube.

[0027] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
