The clamping structure 2 is used to facilitate clamping test tubes of different sizes. A rotor box 28 is fixedly connected to the interior of the box body 1. The top of the rotor box 28 is rotatably connected to the rotor rod 22, and the top of the rotor rod 22 is fixedly connected to the disc 26. The bottom ends of the first support column 3 and the two second support columns 14 are fixedly connected to the disc 26. A control panel 24 is provided on the front side of the box body 1. The control panel 24 is electrically connected to the motor 27 and the rotor box 28 respectively. A heat dissipation hole 23 is provided at the bottom of the box body 1;

[0034] Specifically, first start the motor 27 through the control panel 24. After the motor 27 is started, it will drive the rotating rod 6 to rotate. As the rotating rod 6 rotates, the second bevel gear 7 also starts to rotate. Since the second bevel gear 7 is meshed with the first bevel gear 5, the first bevel gear 5 will also rotate accordingly. At the same time, the threaded rod 4 fixedly connected to the first bevel gear 5 will also rotate. The outer side of the threaded rod 4 is threadedly connected to the connecting rod 8, so the connecting rod 8 will also rotate accordingly. The front and rear ends of the connecting rod 8 are respectively fixedly connected to the limit blocks 11, and the limit blocks 11 can only slide up and down in the second groove 12 opened inside the first support column 3. Since the connecting rod 8 cannot rotate with the threaded rod 4, it can only It can slide up and down along the second groove 12. At the same time, the fixed block 9 fixedly connected to the right side of the connecting rod 8 will also slide up and down through the third groove 13, and the right end of the fixed block 9 is fixedly connected to the first placement plate 10, so the first placement plate 10 will also move up and down accordingly, so that the appropriate height can be adjusted to meet different experimental needs. At this time, the rotor rod 22 in the rotor box 28 is started through the control panel 24 to rotate it, and the rotor rod 22 drives the disc 26 fixedly connected at the upper end to rotate. Since the first support column 3 and the two second support columns 14 are fixedly connected to the disc 26, the disc 26 will drive them to rotate together, so that the entire device can perform centrifugal work.

[0035] Reference Figure 2 、 Figure 4 ,and Figure 5 The clamping structure 2 includes a hollow hole 201, and multiple hollow holes 201 are respectively opened on one side of the corresponding first placement plate 10 and the second placement plate 15. The front and rear sides of the multiple hollow holes 201 are each provided with a first groove 202. A spring 203 is fixedly connected to one side of the first groove 202. One end of the spring 203 is fixedly connected to a clamping plate 204. The outside of the clamping plate 204 is fixedly connected to a rubber pad 25.

[0036] Specifically, in the experiment, a plurality of hollow holes 201 of the same size are designed on one side of the interior of the first placement plate 10 and the second placement plate 15. In order to accommodate test tubes, when we insert the test tubes into these hollow holes 201, the springs 203 in the first grooves 202 opened on the front and rear sides of the hollow holes 201 will play a role. Under the action of its own elastic force, the springs 203 will drive the clamping plate 204 with a rubber pad 25 fixedly connected at one end to clamp the test tube. This ensures that the test tube can be firmly fixed in the hollow hole 201 to prevent the test tube from slipping during the experiment. Since the test tubes vary in size, the springs 203 have a certain degree of elasticity and can be adjusted accordingly according to the diameter of the test tube to adapt to test tubes of different sizes. This makes the equipment suitable for test tubes of various specifications, thereby improving the versatility and practicality of the experimental equipment.

[0037] Reference Figure 1 and Figure 6 A cover plate 20 is provided on the top of the box body 1. The front and rear ends of the right side of the cover plate 20 are fixedly connected with hinges 21. The cover plate 20 is rotatably connected to the box body 1 through the hinges 21. An observation window 16 is provided on the top of the cover plate 20. Handles 17 are fixedly connected to the left and right sides of the top of the cover plate 20. The left end of the cover plate 20 is fixedly connected to a connecting plate 18. The top of the connecting plate 18 is threadedly connected with a bolt 19. One end of the bolt 19 passes through the connecting plate 18 and the box body 1 in sequence.

[0038] Specifically, through the observation window 16 on the cover 20, the staff can observe the internal centrifugal conditions in real time for recording and inspection. By loosening the bolt 19 on the top of the connecting plate 18 at the left end of the cover 20, the cover 20 can be opened. The cover 20 is rotatably connected to the box body 1 through the hinge 21, thereby realizing opening and closing. The entire centrifuge can be picked up by the handle 17 to meet the needs of staff to carry it out.

[0039] Reference Figure 2 and Figure 3 , the interior of the first support column 3 is provided with a second groove 12 on both the front and rear sides, the front and rear sides of the connecting rod 8 are fixedly connected to the limit blocks 11, and the two limit blocks 11 are respectively slidably connected to the corresponding second grooves 12;

[0040] Specifically, the limiting block 11 that slides up and down inside the second groove 12 limits the connecting rod 8 so that the connecting rod 8 can only move up and down together.

[0041] Working principle: When using the device, the motor 27 is first started by relying on the control panel 24, and the motor 27 drives the rotating rod 6 to rotate. At the same time, the rotating rod 6 drives the second bevel gear 7 to rotate, and the first bevel gear 5 meshing therewith also rotates. At the same time, the threaded rod 4 fixedly connected to the first bevel gear 5 also rotates. At this time, the connecting rod 8 connected to the outer thread of the threaded rod 4 rotates accordingly. Since the front and rear ends of the connecting rod 8 are respectively fixedly connected to the limit blocks 11, and the limit blocks 11 can only slide up and down with the second groove 12 opened inside the first support column 3, the connecting rod 8 cannot rotate with the threaded rod 4, but can only slide up and down with the second groove 12. At the same time, the fixed block 9 fixedly connected to the right side of the connecting rod 8 will slide up and down together through the third groove 13, and the first placement plate 10 fixedly connected to the right end of the fixed block 9 will also move up and down together, so as to adapt to the lengths of different test tubes;

[0042] In addition, multiple hollow holes 201 of the same size are respectively opened on one side of the interior of the first placement plate 10 and the second placement plate 15. When the test tube is placed into the hollow hole 201, the spring 203 in the first groove 202 opened on the front and rear sides of the hollow hole 201 will clamp the test tube with the clamping plate 204 with a rubber pad 25 fixedly connected at one end under the action of elastic force. Since the sizes of the test tubes are different, the spring 203 will also expand and contract accordingly to adapt to the size of the test tube.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
