[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] like Figures 1 to 8As shown, this disclosure provides a rotating assembly for a centrifuge and a centrifuge. After the user installs the rotor 20 onto the drive head 11, the locking slider 41 can be slid to the locking position and inserted into the locking groove 21 to lock the rotor 20 onto the drive head 11. The user can also slide the locking slider 41 to the unlocking position to disengage from the locking groove 21, thereby unlocking the rotor 20 from the drive head 11, and then remove the rotor 20 from the drive head 11. This design makes it easier for the user to install or remove the rotor 20 from the drive head 11, improving the user experience.

[0045] like Figures 1 to 8 As shown, this embodiment of the present disclosure provides a rotating assembly for a centrifuge, including a drive assembly 10, a rotor body 20, and a locking assembly 40. The drive assembly 10 includes a drive head 11, which has a clearance groove 111 arranged horizontally. The rotor body 20 has a mounting groove 201 for mounting the drive head 11, and a locking groove 21 is provided in the mounting groove 201 corresponding to the clearance groove 111. The locking assembly 40 includes a locking slider 41, which is slidably disposed in the clearance groove 111. The locking slider 41 can slide along the clearance groove 111 to a locked position so that both ends of the locking slider 41 are located in the locking groove 21 and the clearance groove 111, respectively. Alternatively, the locking slider 41 can slide along the clearance groove 111 to an unlocked position to disengage from the locking groove 21.

[0046] Specifically, the drive assembly 10 also includes a drive pin 12, which is disposed on the side of the drive head 11 facing the rotor body 20, and a drive groove 22 is provided on the rotor body 20 at the position corresponding to the drive pin 12. The length of the clearance groove 111 is greater than or equal to the length of the locking slider 41, so that the locking slider 41 can be completely retracted into the clearance groove 111 when it slides to the unlock position.

[0047] When the user needs to install the rotor body 20, the mounting groove 201 of the rotor body 20 can be placed over the outside of the drive head 11, and the drive pin 12 can be inserted into the drive groove 22. At this time, the locking groove 21 and the yielding groove 111 are aligned with each other. Then, the user can slide the locking slider 41 to the locking position so that both ends of the locking slider 41 are located in the locking groove 21 and the yielding groove 111, respectively. In this way, the locking slider 41 can lock the rotor body 20 to the drive head 11 to counteract the axial upward buoyancy of the rotor body 20, thereby preventing the rotor body 20 from falling off the drive head 11.

[0048] When the user needs to disassemble the rotor body 20, the locking slider 41 can be slid to the unlocked position so that the locking slider 41 is fully retracted into the clearance groove 111. At this time, the locking slider 41 disengages from the locking groove 21, thereby unlocking the rotor body 20 from the drive head 11. Then, the user can remove the rotor body 20 from the drive head 11.

[0049] This design makes it easier for users to install or remove the rotor 20 from the drive head 11, thus improving the user experience.

[0050] In practical applications, when the rotor body 20 is mounted on the drive head 11, the drive head 11 can abut against the inner wall of the mounting groove 201 to counteract the centrifugal force generated when the rotor body 20 rotates.

[0051] Optionally, a clearance notch is provided at the position corresponding to the driving pin 12 on the locking slider 41, so that the driving pin 12 can extend from one side of the locking slider 41 through the clearance notch to the other side of the locking slider 41 and insert into the driving groove 22. This arrangement can reduce the size of the rotating assembly.

[0052] In the above embodiment, the length of the clearance notch is greater than the sum of the thickness of the drive pin 12 and the movement distance of the locking slider 41. The movement distance of the locking slider 41 refers to the distance between the unlocked position and the locked position. This design prevents the drive pin 12 from interfering with the locking slider 41 during its sliding process.

[0053] like Figures 2 to 6 As shown, in some embodiments, the clearance groove 111 is horizontally arranged in the form of passing through the drive head 11; the locking groove 21 is configured as an annular groove; the locking assembly 40 includes two locking sliders 41 that can slide along the clearance groove 111 in opposite directions so that the two locking sliders 41 are respectively inserted into the locking groove 21.

[0054] Specifically, an annular locking groove 21 is provided at the position corresponding to the mounting groove 201 and the clearance groove 111. The left half of the locking groove 21 is aligned with the left end of the clearance groove 111, and the right half of the locking groove 21 is aligned with the right end of the clearance groove 111. The locking assembly 40 includes a left locking slider 41 and a right locking slider 41, which are located in the left and right halves of the clearance groove 111, respectively. In this way, after the rotor body 20 is installed on the drive head 11, the left locking slider 41 can slide to the left and insert into the left half of the locking groove 21, and the right locking slider 41 can slide to the right and insert into the right half of the locking groove 21. With this configuration, the rotor body 20 can be locked to the drive head 11 by the two locking sliders 41, improving the stability of the rotor body 20 installed on the drive head 11.

[0055] In the above embodiment, the length of the clearance groove 111 is greater than or equal to twice the length of the locking slider 41, so that the two locking sliders 41 can be completely housed in the clearance groove 111 at the same time when they slide to the unlock position.

[0056] like Figures 2 to 6 As shown, in some embodiments, the locking assembly 40 further includes a locking elastic member 42. The locking elastic member 42 is disposed between the two locking sliders 41 to elastically connect the two locking sliders 41; wherein the elastic force direction of the locking elastic member 42 is defined to drive the two locking sliders 41 to move in opposite directions.

[0057] Specifically, the locking elastic element 42 is configured as a compression spring. The locking elastic element 42 is positioned between the two locking sliders 41, and its two ends are elastically connected to the two locking sliders 41 respectively. Thus, without external force, the locking elastic element 42 can push the two locking sliders 41 towards the left and right halves of the locking groove 21 respectively, so that the two locking sliders 41 are respectively inserted into the locking groove 21. This configuration prevents the locking sliders 41 from disengaging from the locking groove 21 without human intervention, further improving the stability of the rotor body 20 installed on the drive head 11.

[0058] In the above embodiment, the length of the clearance groove 111 is greater than or equal to the sum of the lengths of the two locking sliders 41 and the length of the locking elastic member 42. The length of the locking elastic member 42 refers to its length after compression.

[0059] like Figures 1 to 8 As shown, in some embodiments, the rotating assembly further includes an unlocking assembly 30. The unlocking assembly 30 includes an unlocking cover 31, which covers the driving head 11 and is movable vertically along the driving head 11. A first guide surface is provided at an angle to the side of the locking slider 41 facing the unlocking cover 31. When the unlocking cover 31 moves toward the locking slider 41, the edge of the unlocking cover 31 can push the first guide surface, causing the locking slider 41 to slide into the clearance groove 111.

[0060] Specifically, the unlocking cover 31 covers the drive head 11 and is located above the locking slider 41. The locking slider 41 has an inclined surface on the side facing the unlocking cover 31 to form a first guide surface, and this first guide surface is inclined downwards along the direction close to the locking groove 21. Thus, when the rotor body 20 needs to be disassembled, the user can move the unlocking cover 31 downwards along the drive head 11. At this time, the lower edge of the unlocking cover 31 abuts against the first guide surface, and the locking slider 41 is pushed into the clearance groove 111 via the first guide surface.

[0061] Optionally, a clearance notch is also provided at the position corresponding to the drive pin 12 on the unlock cover 31, so that the drive pin 12 can extend from one side of the unlock cover 31 through the clearance notch to the other side of the unlock cover 31.

[0062] like Figures 3 to 8 As shown, in some embodiments, the unlock cover 31 is provided with a second guide surface corresponding to the first guide surface; wherein the tilt angle of the second guide surface is the same as that of the first guide surface, so that the second guide surface can be completely fitted to the first guide surface.

[0063] Specifically, the lower edge of the unlocking cover 31 is provided with an inclined surface corresponding to the first guide surface to form a second guide surface, and the second guide surface is inclined downward along the direction close to the locking slide groove 21. In this way, the unlocking cover 31 can achieve surface contact with the first guide surface of the locking slider 41 through the second guide surface, making it easier for the user to push the locking slider 41 into the clearance slide groove 111 through the unlocking cover 31. At the same time, the surface contact can also reduce the possibility of damage to the unlocking cover 31 and the locking slider 41, improving the reliability of the centrifuge.

[0064] like Figures 3 to 8 As shown, in some embodiments, the unlocking component 30 further includes an unlocking elastic member 32. The unlocking elastic member 32 is disposed between the unlocking cover 31 and the driving head 11 to elastically connect the unlocking cover 31 and the driving head 11; wherein the elastic force direction of the unlocking elastic member 32 is defined as pushing the unlocking cover 31 away from the driving head 11.

[0065] Specifically, the unlocking elastic element 32 is configured as a compression spring. The unlocking elastic element 32 is positioned between the unlocking cover 31 and the drive head 11, with both ends elastically connected to the unlocking cover 31 and the drive head 11, respectively. Thus, without external force, the unlocking elastic element 32 can push the unlocking cover 31 away. This configuration prevents the unlocking cover 31 from interfering with the movement and resting positions of the locking slider 41 when it slides into the locking groove 21, thereby ensuring the stability of the rotor body 20 locked to the drive head 11.

[0066] like Figures 3 to 8 As shown, in some embodiments, the unlocking assembly 30 further includes a rotor handle and an unlocking button 34. The rotor handle is disposed on the other side of the unlocking cover 31 relative to the drive head 11, and a vertical unlocking groove 331 is provided at the position corresponding to the unlocking cover 31. The unlocking button 34 is slidably disposed in the unlocking groove 331. The unlocking button 34 can slide along the unlocking groove 331 toward the unlocking cover 31 to push the unlocking cover 31 toward the locking slider 41.

[0067] Specifically, the rotor handle is positioned on the opposite side of the unlocking cover 31 relative to the drive head 11, and is fixedly mounted to the rotor body 20 by bolts or other fasteners. An unlocking groove 331 is vertically positioned corresponding to the rotor handle and the unlocking cover 31. An unlocking button 34 is located within the unlocking groove 331. Thus, the user can slide the unlocking button 34 downwards along the unlocking groove 331 to push the unlocking cover 31 towards the locking slider 41, thereby unlocking the device.

[0068] Optionally, when the unlock button 34 slides upward and is completely disengaged from the unlock cover 31, the lower end of the unlock button 34 can slide completely into the unlock groove 331.

[0069] like Figure 7 and Figure 8 As shown, in some embodiments, the unlocking groove 331 is provided in the form of penetrating the rotor handle; the length of the unlocking button 34 is greater than the length of the unlocking groove 331.

[0070] Specifically, the unlocking groove 331 extends vertically through the rotor handle, and the length of the unlocking button 34 is greater than the length of the unlocking groove 331. In this way, the unlocking button 34 can pass through the unlocking groove 331 from below the rotor handle and extend to the top of the rotor handle, and the user can directly press the upper end of the unlocking button 34 to unlock the rotor body 20 to the drive head 11.

[0071] Optionally, the upper end of the unlock button 34 is provided with a button cap 341, which allows the user to press the unlock button 34, thus improving the user experience.

[0072] like Figure 7 and Figure 8 As shown, in some embodiments, the unlocking assembly 30 further includes a reset elastic member 35. The reset elastic member 35 is disposed within the unlocking groove 331 to elastically connect the rotor handle and the unlocking button 34; wherein the elastic force direction of the reset elastic member 35 is defined to push the unlocking button 34 away from the unlocking cover 31.

[0073] Specifically, the reset elastic element 35 is configured as a compression spring. The reset elastic element 35 is sleeved on the unlock button 34, and its two ends are elastically connected to the upper end of the unlock button 34 and the rotor handle, respectively. In this way, without external force, the reset elastic element 35 can push the unlock button 34 away from the unlock cover 31, so that the unlock button 34 is disengaged from the unlock cover 31.

[0074] In the above embodiment, when a button cap 341 is provided at the upper end of the unlock button 34, the upper end of the reset elastic member 35 is elastically connected to the lower end of the button cap 341.

[0075] likeFigure 7 and Figure 8 As shown, optionally, the unlocking slide 331 and the unlocking button 34 are respectively provided with a first limiting protrusion 332 and a second limiting protrusion 342, and the first limiting protrusion 332 is located above the second limiting protrusion 342. In this way, when the unlocking button 34 moves upward along the unlocking slide 331 to the limit position, the first limiting protrusion 332 can abut against the second limiting protrusion 342 to stop the unlocking button 34 from continuing to move upward, thereby preventing the unlocking button 34 from falling out of the unlocking slide 331.

[0076] like Figure 7 and Figure 8 As shown, optionally, a groove is provided on the outer periphery of the rotor handle. This allows the user to first insert their index and middle fingers into the groove from both sides of the rotor handle and grip it upwards. Then, the user can press down on the unlock button 34 with their thumb. This design makes the unlocking process more in line with user habits, further improving the user experience.

[0077] like Figures 1 to 8 As shown, this disclosure also provides a centrifuge including: a centrifuge body and the aforementioned rotating assembly for the centrifuge. The rotating assembly for the centrifuge is mounted on the centrifuge body.

[0078] Specifically, the centrifuge body also includes a drive motor, which is connected to the drive head 11. Thus, when the rotor 20 is mounted on the drive head 11, the drive motor can drive the rotor 20 to rotate synchronously through the drive head 11 to achieve the centrifugation of the sample.

[0079] The centrifuge using the rotating assembly provided in this application allows the locking slider 41 to slide to the locked position and insert into the locking groove 21 after the user installs the rotor 20 onto the drive head 11, thereby locking the rotor 20 onto the drive head 11. Alternatively, the user can slide the locking slider 41 to the unlocked position to disengage from the locking groove 21, thus unlocking the rotor 20 from the drive head 11, and then remove the rotor 20 from the drive head 11. This design makes it easier for the user to install or remove the rotor 20 from the drive head 11, improving the user experience.
