[0024] The anti-splash mechanism 2 includes a U-shaped plate 8, which is fixedly connected to the middle of the top wall of the lower pressure block 7. A groove 9 is provided in the middle of the top wall of the U-shaped plate 8. A bidirectional screw 10 is rotatably connected to the middle of the inner side of the groove 9. Threaded blocks 11 are threadedly connected to the left and right sides of the outer periphery of the bidirectional screw 10. During the movement of the threaded blocks 11, they can drive the clamping plates 13 fixed thereto to move synchronously. The clamping plates 13 are fixedly connected to the middle of the bottom wall of the threaded blocks 11. A limit rod 6 is fixedly connected to the middle of the bottom wall of the lower pressure block 7. Multiple sets of annularly distributed sealing plugs 14 are fixedly connected to the lower part of the outer wall of the lower pressure block 7. The limit rod 6 is slidably connected to the inner side of the limit hole 5. The sealing plug 14 can be accurately inserted into the corresponding test tube 17 during the downward movement. The limit hole 5 is located in the middle of the top wall of the rotating cylinder 4. A knob 12 is fixedly connected to the left end of the bidirectional screw 10. Rotating the knob 12 can make the bidirectional screw 10 rotate.

[0025] The rotating drum 4 has positioning grooves 15 on both the left and right sides of its outer top edge. The positioning grooves 15 are in clearance fit with the clamping plate 13. The positioning grooves 15 can determine the position of the clamping plate 13, so that the clamping plate 13 can better clamp and fix the rotating drum 4.

[0026] The centrifuge body 1 has an installation groove 3 on the left side of the top wall, and the rotating drum 4 is located in the middle of the inner side of the installation groove 3. The liquid in the internal test tube 17 is centrifuged by rotating the rotating drum 4.

[0027] Among them, multiple sets of annularly distributed placement grooves 16 are provided on the outer side of the limiting hole 5 on the top wall of the rotating cylinder 4. Test tubes 17 are slidably connected to the inner side of each placement groove 16, and each sealing plug 14 corresponds to a test tube 17.

[0028] The centrifuge body 1 has multiple sets of evenly distributed heat dissipation holes 21 on both the left and right side walls. The left rear end of the top wall of the centrifuge body 1 is rotatably connected to a sealing cover 23 via a hinge 22. The sealing cover 23 can cover the mounting groove 3.

[0030] Among them, a cover plate 24 is fixedly connected to the middle of the front wall of the sealing cover 23, and the cover plate 24 is fitted with the mounting groove 3 with clearance.

[0031] Working principle: When the centrifuge is needed, after placing the test tube 17 into the corresponding placement slot 16, align the limiting rod 6 with the limiting hole 5 and push the lower pressure block 7 downward. During the downward movement of the lower pressure block 7, the outer sealing plug 14 is inserted into the corresponding test tube 17 opening to perform a one-to-one sealing treatment on the test tube 17 opening. After inserting the sealing plug 14 into the test tube 17 opening, turn the knob 12. During the rotation of the knob 12, the bidirectional screw 10 rotates, thereby bringing the two threaded blocks 11 closer to each other. During the process of the threaded blocks 11 moving closer to each other, the clamping plate 13 moves to the inside of the positioning slot 15. With the cooperation of the two sets of clamping plates 13, the rotating drum 4 is connected and fixed to the lower pressure block 7, thereby preventing the sealing plug 14 from separating from the test tube 17.
