Sleeve rotor for centrifugal machine

Abstract

The invention discloses a sleeve rotor for a centrifugal machine. The sleeve rotor comprises a main body assembly, rotating assemblies, a connecting assembly, an inserting assembly and fixing assemblies. The main body assembly comprises a base, a motor, a supporting plate, a first connecting rod, a cover body and first inserting rods. Each rotating assembly is installed at the top of the first connecting rod and comprises an outer sleeve, an inner sleeve, sliding blocks, sliding grooves, through holes, a rod body and first inserting grooves. According to the sleeve rotor for the centrifugal machine, test tubes are placed in the through holes, the test tubes penetrate through the through holes to enter second tube bodies, quarter oval plate bodies are pressed, and the quarter oval plate bodies move towards one sides close to the inner walls of the second tube bodies to drive second arc-shaped plates to extrude springs, so that the test tubes can enter among four second arc-shaped plates; and due to the reverse push force of the springs, the positions of the test tubes are fixed, so that the test tubes with different inner diameters are fixed by self-adapting the test tube inner diameters to adjust the distance without frequently replacing a tube rack, and a large amount of experiment time is saved.

Description

technical field [0001] The invention relates to the technical field of centrifuge rotors, in particular to a centrifuge sleeve rotor. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. The magnitude of the centrifugal force is determined by the rotation speed, the radius of rotation and the melting quality of the substance; [0003] During the working process of the centrifuge, the motor drives the centrifuge rotor to rotate at a high speed. During the high-speed rotation of the centrifuge rotor, the internal structure of the rotor also rotates with the rotor; [0004] People use centrifuge rotors to load various test tubes and perform centrifugation. Especially in the process of conducting experiments, it is often necessary to prepare experimental test tubes and many comparison test tubes to ensure the accuracy of the experiment. [0005] However, when ...

AI Technical Summary

Problems solved by technology

[0006] 1. The centrifuge rotor is fixed for the test tube, and its inner diameter is often fixed. When fixing test tubes with different inner diameters, the rotor needs to be replaced according to the inner diameter of the test tube. A lot of time will be wasted in the process of replacing the rotor , and in the process of centrifugation experiments, various test tubes with different inner diameters need to be centrifuged, but after each experiment, the rotor needs to be replaced once, which greatly wastes the experiment time and reduces the experiment efficiency;

[0007] 2. In the process of experimentation, the number of experimental test tubes and comparison test tubes is often large. Although the existing centrifugal rotors can be stacked and used, the height of each test tube is not the same. When the number of test tubes is large , it is necessary to stack a lot of tube racks at this time, but the distance between the tube racks cannot be adjusted. If the distance between the tube racks is too long, there is a problem of wasting space. The bottom wall of the rack is in contact, or the tube rack crushes the test tube, which is not conducive to the experiment
