A vertical groove 22 is formed on the inner wall of the inner box 2, and the vertical groove 22 is adapted to the inner cylinder 31. Two sets of vertical grooves 22 and inner cylinders 31 are provided, symmetrically arranged. An arc groove 23 is formed at the bottom of the vertical groove 22, and a fixing block 32 is adapted to the arc groove 23. A compression groove is formed on the outside of the centrifuge cylinder 3. The locking assembly B33 includes a spring B333 fixedly connected to the inner wall of the compression groove. A magnetic block B332 is fixedly connected to one end of the spring B333, and a magnetic block B332 is fixed to one side. A locking block B331 is fixedly connected, and a positioning hole 24 is opened on the inner wall of the inner box 2. The locking block B331 is set to correspond with the positioning hole 24. When the centrifuge tube 3 needs to be installed, the centrifuge tube 3 is placed inside the inner box 2. The fixing block 32 is aligned with the vertical groove 22. When the vertical groove 22 moves to the bottom, the centrifuge tube 3 is rotated, and the fixing block 32 is moved to the bottom of the arc groove 23. At the same time, as the centrifuge tube 3 rotates, the locking block B331 is aligned with the positioning hole 24. Under the action of the restoring force of the spring B333, the locking block B331 is driven to insert into the positioning hole 24, and the automatic locking is completed.

[0027] The inner box 2 has a vertical groove. The unlocking component 4 includes a rod 42 set inside the vertical groove. A rotating ring 41 is fixedly connected to the upper surface of the rod 42. The rotating ring 41 is set on the upper surface of the inner box 2. A magnetic block A44 is fixedly connected to the bottom end of the rod 42. The magnetic blocks A44 and B332 are magnetically repelled. During normal use, the unlocking component 4 is set inside the vertical groove. When it is necessary to remove the centrifuge cylinder 3, the rotating ring 41 is held to lift the rod 42. The magnetic blocks A44 and B332 are magnetically repelled, causing the locking block B331 to retract into the compression groove. Then the centrifuge cylinder 3 can be rotated to remove the centrifuge cylinder 3.

[0028] The outer side of the insertion rod 42 is provided with an external thread 43. The insertion rod 42 is connected to the vertical groove thread through the external thread 43. When installing the unlocking component 4, it is fixed by connecting the external thread 43 to the vertical groove thread to ensure stability during normal use.

[0029] A motor is installed inside the inner box 2. A rotating shaft is fixedly connected to the output end of the motor. The rotating shaft passes through the bottom surface of the inner wall of the inner box 2 and is fixedly connected to the main gear 14. A rotating rod is rotatably connected to the bottom surface of the inner box 2. A secondary gear 15 is fixedly connected to the upper end of the rotating rod.

The retaining ring is adapted to the ring groove 161. After the centrifuge cylinder 3 is installed, the retaining ring on the bottom surface of the inner cylinder 31 will be inserted into the ring groove 161 to complete the fixation. During centrifugation, the motor drives the main gear 14 to rotate. The secondary gear 15 and the rack ring 16 drive the inner cylinder 31 to rotate inside the centrifuge cylinder 3 to complete the centrifugation work.

[0030] The centrifuge body 1 has a movable groove 13 on its inner wall, and a positioning groove 131 on one side of the movable groove 13. A positioning block adapted to the positioning groove 131 is fixedly connected to the outer side of the inner box 2. The positioning block is slidably connected inside the positioning groove 131.

Inside the movable groove 13, a push block 211 is fixedly connected to the upper surface of the locking block A212. The push block 211 is slidably connected inside the movable groove 13. When disassembling and assembling the inner box 2, push the push block 211 by hand to cause the spring A213 to squeeze and retract the locking block A212 inside the movable groove 13. Then, align the positioning block with the positioning groove 131 and place it. After placing it, release the push block 211. Under the restoring force of the spring A213, the locking block A212 moves to block the top of the positioning block, thus completing the locking effect.

Through the setting of the sealing groove 12, together with the top cover 11 and the sealing strip, a stable sealing effect is achieved during centrifugation.

[0032] Specifically, through the locking component B33 and the unlocking component 4, when centrifuge cylinder 3 needs to be installed, centrifuge cylinder 3 is placed inside inner box 2, with fixing block 32 corresponding to vertical groove 22. When vertical groove 22 moves to the bottom, centrifuge cylinder 3 is rotated, moving fixing block 32 to the bottom of arc groove 23. Simultaneously, as centrifuge cylinder 3 rotates, locking block B331 aligns with positioning hole 24. Under the restoring force of spring B333, locking block B331 is inserted into positioning hole 24, completing automatic locking. When centrifuge cylinder 3 needs to be removed, rotating ring 41 moves insertion rod 42 upward, utilizing... The magnetic repulsion between magnetic block A44 and magnetic block B332 causes locking block B331 to retract into the compression groove. Then, the centrifuge cylinder 3 can be rotated. When disassembling and assembling the inner box 2, push the push block 211 by hand to drive the spring A213 to squeeze and retract the locking block A212 into the movable groove 13. Then, align the positioning block with the positioning groove 131 and place it. After placing it, release the push block 211. Under the restoring force of the spring A213, the locking block A212 will move to block the top of the positioning block, completing the locking effect. Finally, the centrifuge cylinder 3 can be disassembled, achieving the purpose of quick disassembly and assembly of the centrifuge cylinder 3 for easy maintenance.
