[0037] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0038] A serum purification device for rat serum detection includes: a shell body 1, test tubes 5 and a sealing plate 4, wherein the shell body 1 and the sealing plate 4 are connected together.

[0039] The first groove 6 is provided on the upper surface of the outer shell body 1;

[0040] Adjustment component 3 is set inside the first groove 6 and is used to adjust the number of holes of the fixed test tube 5 according to the number of test tubes 5, so as to make it more balanced when rotating.

[0041] The motor 11 is located at the top of the first groove 6, and the output end of the motor 11 is connected to the rotating drum 10. Several limiting blocks 9 are provided on the outer wall of the rotating drum 10.

[0042] Preferably, the adjustment assembly 3 includes a fixing ring 32 disposed on the inner wall of the first groove 6 and a plurality of rotating frames 34 disposed at the eaves of the rotating cylinder 10, with a toothed block 35 connected to one end of each rotating frame 34.

[0043] The fixing ring 32 has a toothed groove 33 inside, and the toothed groove 33 and the toothed block 35 are engaged in a snap-fit ​​relationship.

[0044] A sliding bracket 31 is connected to the lower surface of the fixed ring 32.

[0048] Preferably, the outer wall of the fixing ring 32 is provided with a plurality of second grooves 13 arranged at equal intervals, and the inner wall of the second grooves 13 is provided with rollers 12 for rotation.

[0049] Preferably, the inner wall of the sliding frame 31 is provided with a plurality of magnetic blocks 8;

[0050] A magnetic ring 7 is provided at the bottom of the first groove 6, and the magnetic ring 7 and the magnetic block 8 are magnetically repelled.

[0051] Preferably, the sliding frame 31 is fitted between the rotating cylinder 10 and the limiting block 9.

[0052] Preferably, a controller 2 is provided on the front end face of the outer casing 1.

[0053] Example 1

[0054] In this embodiment, refer to Figures 1 to 6 To address the issues of accelerated wear and tear on the rotating drum 10 during centrifugation due to the mismatch between the number of test tubes 5 and the number of wells on the centrifuge, as well as the problem of excessive noise, the specific technology is as follows:

This allows the entire adjustment assembly 3 to operate more stably. A magnetic ring 7 is provided at the bottom of the first groove 6, and multiple magnetic blocks 8 are provided on the sliding frame 31. By utilizing the mutual repulsion of like poles between the magnetic blocks 8 and the magnetic ring 7, the sliding frame 31 can be lifted up, which can effectively reduce the friction caused by the shaking of the sliding frame 31 and the bottom of the first groove 6, thereby making the centrifugation process smoother and reducing noise.
