Centrifugal machine rotor locking structure and centrifugal machine

Abstract

The invention provides a centrifugal machine rotor locking structure. The centrifugal machine rotor locking structure comprises a first locking element, a second locking element being and a circular cone end, wherein the first locking element rotates around a first driving shaft and is provided with a first near end, a first far end and a first tail end extending inwards from the first near end; the first tail end is provided with a first circular arc surface protruding inwards; the second locking element is symmetric with and opposite to the first locking element and rotates around a second driving shaft; the second locking element is provided with a second near end, a second far end and a second tail end extending inwards from the second near end; the second tail end is provided with a second circular arc surface protruding inwards; the diameter of the circular cone end gradually increases from top to bottom; the circular cone end can be operated to move upwards to extend into the space between the first tail end and the second tail end or move downwards to retreat from the space between the first tail end and the second tai; when the circular cone end extends into the space between the first locking element and the second locking element, the outer surface of the circular cone end makes contact with a first arc surface and a second arc surface, and the first far end and thesecond far end rotate inwards. The invention further discloses a centrifugal machine. The centrifugal machine rotor locking structure and the centrifugal machine have the advantages of being stable instructure and high in rotor dismantling efficiency.

Description

technical field [0001] The invention belongs to the technical field of centrifuges, and in particular relates to a centrifuge rotor locking structure and a centrifuge adopting the centrifuge rotor locking structure. Background technique [0002] The centrifuge rotor is mounted on the centrifuge. This centrifuge is mainly used in laboratories for research in the fields of medicine, pharmacy, biology, and chemistry to separate components of samples using mass inertia. The rotor of the centrifuge needs to rotate at a high speed, and the sample container is arranged on the rotor in different ways, and the sample to be centrifuged is stored in the sample container and rotated. The rotor is rotated by a motor. [0003] In order to deal with different analytical samples and meet the requirements of different experiments. The rotor requires frequent disassembly. In the prior art, it is designed that the rotor can be connected with the motor shaft through a specific clamping stru...

AI Technical Summary

Problems solved by technology

[0006] The invention aims at the problem that the deflection of the coupling element in the prior art is realized by the extrusion of the truncated cone surface of the rotor sleeve, which is easy to deform and further leads to the problem that the locking is not in place, and designs and provides a centrifuge rotor locking structure
