[0022] The present invention will be further described below in conjunction with the embodiments.
[0023] See also Figure 1-Figure 13 The balancing assembly 35 includes a horizontal inclined block 351, and there are two groups of the horizontal inclined blocks 351.

When the centrifuge is in a balanced static state, the water inlet groove 382 is fitted with the inner baffle 391, thereby preventing the coolant inside the liquid storage box 39 from entering the inside of the balancing box 381.

[0029] A drainage assembly 384 for draining liquid is provided at the bottom of the balancing box 381, and the drainage assembly 384 includes a sealing plate 3841 provided on the bottom surface of the inner wall of the balancing box 381, and a connecting short block 3842 is fixedly connected to the bottom surface of the sealing plate 3841, and the connecting short block 3842 passes through the bottom surface of the balancing box 381, and a magnetic plate A3843 is fixedly connected to the bottom surface of the connecting short block 3842, and a spring A3844 is fixedly connected to the surface of the magnetic plate A3843, and the upper end of the spring A3844 is fixedly connected to the bottom surface of the balancing box 381. The liquid outlet component 4 includes a fixed connection to the liquid storage The bottom box 41 at the bottom of the box 39 is a hollow structure. The inner wall of the bottom box 41 is fixedly connected with an electromagnet 411. The electromagnet 411 and the magnetic plate A3843 are arranged correspondingly. When the centrifugation is completed and the coolant inside the balance box 381 needs to be discharged, the electromagnet 411 is energized, and the magnetic plate A3843 is driven to move upward by the magnetic repulsion between the electromagnet 411 and the magnetic plate A3843. The spring A3844 is compressed and the short block 3842 and the sealing plate 3841 are connected to move upward at the same time, and the internal coolant flows out from the rising position of the sealing plate 3841 to complete the discharge.
[0030] A liquid discharge oblique pipe 42 is fixedly connected to one side of the bottom box 41, a vertical pipe 44 is fixedly connected to one side of the liquid discharge oblique pipe 42, a mounting chassis 43 is fixedly connected to the bottom surface of the vertical pipe 44, the bottom box 41, the liquid discharge oblique pipe 42 and the vertical pipe 44 are internally connected, a solenoid valve 46 is provided at the connection between the liquid discharge oblique pipe 42 and the vertical pipe 44, an electric telescopic rod 45 is fixedly connected to the bottom surface of the mounting chassis 43, one end of the electric telescopic rod 45 passes through the mounting chassis 43 and is fixedly connected to a liquid pressure plate 47, a one-way pressure valve A is provided inside the liquid pressure plate 47, the upper end of the vertical pipe 44 is fixedly connected to the bottom surface of the liquid storage tray 5 and The interior is connected, and a one-way pressure valve B48 is provided at the connection point between the vertical pipe 44 and the liquid storage pan 5. After the coolant is discharged from the balance box 381 and flows into the bottom box 41, it flows into the interior of the vertical pipe 44 through the drainage inclined pipe 42, and then the solenoid valve 46 is opened to close the connection between the drainage inclined pipe 42 and the vertical pipe 44. The liquid pressure plate 47 is pressed down by the electric telescopic rod 45, and the coolant below flows to the surface of the liquid pressure plate 47 through the one-way pressure valve A. The coolant moves upward by the upward movement of the liquid pressure plate 47, so that the coolant squeezes the one-way pressure valve B48 and pours the coolant back into the liquid storage pan 5.
[0031] A magnetic plate C345 is fixedly connected to the outer side of the annular plate 341, and the magnetic plate C345 is corresponding to the buffer pad B343. A push tube assembly 36 for pushing the centrifuge tube is arranged on one side of the placement frame 311, and the push tube assembly 36 includes a side plate 361 fixedly connected to one side of the placement frame 311, and a spring B362 is fixedly connected to the inner wall of the side plate 361. A push plate 363 is fixedly connected to one side of the spring B362. The push plate 363 and the magnetic plate C345 repel each other magnetically. During the rotation of the annular plate 341, due to the magnetic repulsion between the magnetic plate C345 and the push plate 363, the push plate 363 is always compressed inside the side plate 361. After the annular plate 341 is rotated and moved away, the push plate 363 pops out under the action of the spring B362, and pushes the centrifuge tube into the placement groove B3131, ensuring that the centrifuge tube can stably enter the placement groove B3131.
[0032] Specifically, during the test, the centrifuge tube is first placed in the placement groove A313. Under the action of the gravity of the centrifuge tube, the soft cushion pressure plate 314 is pressed down, so that the spring rod 317 drives the connecting inclined block 37 to press down. During the downward movement of the connecting inclined block 37, the inner wall of the connecting inclined block 37 presses against the horizontal inclined block 351, driving the horizontal inclined block 351 to move to the other side, thereby driving the connecting inclined block 37 at the other end to move up, and the balance box 381 under the connecting inclined block 37 moves up at the same time. When the balance box 381 moves upward, the water inlet groove 382 is separated from the inner baffle 391. After the water inlet groove 382 is exposed, the coolant enters the balance box 381 from it. The balance groove 383 is used to balance the air pressure. The coolant enters to increase the weight inside the balancing component 38 to achieve automatic balancing. As the balancing progresses, the previously raised connecting bevel block 37 gradually descends until both sides are balanced. Then the insert rod 24 is inserted into the insertion hole 355 to limit the connecting long plate 354 to ensure the stability of the connecting long plate 354 during the centrifugation process. The cover ring 21 is placed above the arc-shaped ring plate 33 to prevent the centrifuge tube from slipping off. The magnetic block D23 is matched with the magnetic plate B344. The magnetic block D23 and the magnetic plate B344 are attracted to each other. When the cover ring 21 rotates, the annular plate 341 is driven to rotate, thereby switching the buffer pad B343 to the correspondence with the side groove 342 and the centrifuge tube, so that the centrifuge The tube enters the placement slot B3131, and then the motor is turned on to complete the centrifugal operation. During the centrifugal process, the centrifugal tube is tilted and pressed down under the action of centrifugal force, driving the soft cushion pressure plate 314 to be further pressed down, thereby squeezing the air inside the air storage tank 315, so that the air bag is inflated, and the cushion pad A312 is used to fit the centrifugal tube more stably to ensure the clamping effect. After the centrifugal operation is completed, when the coolant inside the balance box 381 needs to be discharged, the electromagnet 411 is energized, and the magnetic plate A3843 is driven to move upward by the magnetic repulsion between the electromagnet 411 and the magnetic plate A3843. At the same time, the spring A3844 is compressed, and the short block 3842 and the sealing plate 3844 are connected. 841 moves upward, and the internal coolant flows out from the rising part of the sealing plate 3841. After the coolant is discharged from the balance box 381 and flows into the bottom box 41, it flows into the interior of the vertical pipe 44 through the drainage inclined pipe 42. Then, the solenoid valve 46 is opened to close the connection between the drainage inclined pipe 42 and the vertical pipe 44, and the pressure plate 47 is pressed down by the electric telescopic rod 45. The coolant below flows to the surface of the pressure plate 47 through the one-way pressure valve A, and the coolant moves upward through the upward movement of the pressure plate 47, so that the coolant squeezes the one-way pressure valve B48, and the coolant is poured back into the liquid storage tray 5 for repeated use, thereby achieving the purpose of automatic balancing when the centrifuge tube is placed and enhancing the fixing effect.
