[0014] A high-stability centrifuge device comprises a centrifuge frame and a centrifuge body. The centrifuge body is located above a support plate and is disposed against a plurality of annular covers.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The centrifuge frame and high-stability centrifuge device are provided with a speed reduction mechanism, etc., so that when the centrifuge body is unbalanced during the centrifugal process, the centrifuge body will deviate on the support plate, and at this time, it will abut against the arc cover on one side, so that the arc cover can be pushed to move into the liquid storage chamber, and the reset spring is compressed. At the same time, the damping liquid in the liquid storage chamber can be squeezed, and the gravity plate can be pushed to move upward, which can play a buffering effect. When the gravity plate moves upward, the rack can be driven to move upward through the moving rod, and the gear can be driven to rotate. When the gear rotates, the friction plate can be driven to rotate through the rotating rod. Under the action of the first spring, the friction block and the friction plate can always abut against each other, so that the gravity plate can be decelerated and the generated energy can be consumed, so that the buffering effect is better, and the damage such as shaking and deformation of the centrifuge frame in the horizontal direction is avoided, and its support effect is guaranteed, thereby making the centrifuge device more stable and reliable.

[0016] The centrifuge frame and high-stability centrifuge device are provided with a first pushing mechanism, etc., so that when the centrifuge body deviates to one side, the gravity plate is pushed upward by the damping fluid. When the gravity plate moves upward, the pushing plate can be driven upward by the connecting rod, so that the inclined surface abuts against the side wall of the counterweight plate, thereby pushing the counterweight plate to move in the direction opposite to the deflection direction. At the same time, the rubber ring is deformed, so that the support plate can be counterweighted to avoid the deviation of its center of gravity, which is more stable and reliable.

[0017] The centrifuge frame and high-stability centrifuge device are provided with a knocking mechanism, etc., so that when the rotating rod rotates, the rubber cone block can be driven to rotate synchronously. When the rubber cone block abuts against the side wall of the moving plate, the moving plate and the knocking rod can be pushed to move. At the same time, the second spring is compressed. When the rubber cone block passes over the moving plate, the moving plate and the knocking rod can move and reset under the action of the second spring. In this way, the knocking rod can knock and vibrate the side wall of the centrifuge body to prevent the material from adhering to the inner wall. At the same time, the material in the centrifuge body can be made more uniform, thereby making the centrifuge device more stable and reliable.

[0018] The centrifuge frame and high-stability centrifuge device are provided with a shaking mechanism, etc., so that when in use, the lifting module drives the moving ring and the L-shaped plate to move upward, so that the top of the L-shaped plate contacts the bottom of the second fixed ring, and at the same time, the ball contacts the bottom of the support plate, thereby driving the support plate and the centrifuge body to move upward, and the fourth spring is stretched. After the support plate and the centrifuge body move upward into place, materials are added into the centrifuge body, and then the L-shaped plate is driven downward by the lifting module, and at the same time, the support plate and the centrifuge body can be driven downward. When the end of the push rod abuts against the triangular block, the support plate can be pushed to move. At the same time, the third spring is compressed, and the guide rod moves upward along the guide tube. The fourth spring is stretched. When the push rod passes over the triangular block, the push rod can move under the action of the third spring. The support plate and the centrifuge body can be reset dynamically under the action of the fourth spring, and the heights of the triangular blocks on each L-shaped frame are staggered. In this way, the centrifuge body can be reciprocated and shaken from multiple directions to make the material inside more uniform, ensuring that the subsequent centrifugation is more stable and reliable. In addition, when the support plate moves downward, it can drive the guide rod to move downward along the guide tube. The fourth spring is gradually reset. When the socket and the pin are aligned, the electromagnet is energized to attract the iron block, so that the push ring moves downward. The sixth spring is compressed, and the push ring slides downward along the top of the inclined plate, thereby pushing the moving block to move in the direction close to the fixed block. At the same time, the fifth spring is compressed, and the pin is inserted into the socket for limiting. At this time, the support plate can be prevented from moving, ensuring the subsequent support effect on the centrifuge body. BRIEF DESCRIPTION OF THE DRAWINGS

When the socket 701 is aligned with the latch 704, the electromagnet 905 is energized to attract the iron block 904, so that the push ring 804 moves downward, the sixth spring 903 is compressed, and the push ring 804 slides downward along the top of the inclined plate 703, thereby pushing the moving block 702 to move in the direction close to the fixed block 802. At the same time, the fifth spring 803 is compressed, and the latch 704 is inserted into the socket 701 for limiting. At this time, the support plate 12 can be prevented from moving, thereby ensuring the subsequent support effect on the centrifuge body 10.

[0042] When in use, when the centrifuge body 10 is unbalanced during the centrifugal process, the centrifuge body 10 will deviate on the support disk 12. At this time, it will abut against the arc cover 21 on one side, so that the arc cover 21 can be pushed to move into the liquid storage chamber 20, and the reset spring 2703 is compressed. At the same time, the damping liquid in the liquid storage chamber 20 can be squeezed, and the gravity disk 23 can be pushed to move upward, which can have a buffering effect. When the gravity disk 23 moves upward, the rack 306 can be driven to move upward through the moving rod 305, and the gear 307 can be driven to rotate. When the gear 307 rotates, the friction disk 304 can be driven to rotate through the rotating rod 302. Under the action of the first spring 311, the friction block 303 and the friction disk 304 can always abut against each other, so that the gravity disk 23 can be decelerated and the generated energy can be consumed, so that the buffering effect is better, avoiding damage such as shaking and deformation in the horizontal direction of the centrifuge frame, ensuring its support effect, and making the centrifuge device more stable and reliable.

[0043] At the same time, when the centrifuge body 10 deviates to one side, the gravity plate 23 is pushed upward by the damping fluid. When the gravity plate 23 moves upward, the push plate 202 can be driven upward by the connecting rod 201, so that the inclined surface 203 abuts against the side wall of the counterweight plate 25, thereby pushing the counterweight plate 25 to move in the direction opposite to the deflection direction. At the same time, the rubber ring 26 is deformed, so that the support plate 12 can be counterweighted to prevent its center of gravity from shifting, which is more stable and reliable.

[0044] Furthermore, when the rotating rod 302 rotates, the rubber cone block 406 can be driven to rotate synchronously. When the rubber cone block 406 abuts against the side wall of the movable plate 404, the movable plate 404 and the knocking rod 405 can be pushed to move. At the same time, the second spring 403 is compressed. When the rubber cone block 406 passes over the movable plate 404, the movable plate 404 and the knocking rod 405 can move and reset under the action of the second spring 403. This reciprocating process can make the knocking rod 405 knock and vibrate the side wall of the centrifuge body 10 to prevent the material from adhering to the inner wall. At the same time, the material in the centrifuge body 10 can be made more uniform, thereby making the centrifuge device more stable and reliable.
