Level rotor provided with pin subassembly

Abstract

The invention relates to a level rotor provided with a pin subassembly. The level rotor consists of a level rotor main body and a pin subassembly, wherein the level rotor main body is composed of four Y-shaped subassemblies which are uniformly distributed with bottoms interconnected; the pin subassembly is composed of a rotary pin, a rotary pin hoop, a rotary pin pressing ring, and a retaining ring for a shaft; the rotary pin is arranged in a through hole placed on a branch at the upper part of the Y-shaped mechanism; two grooves provided with two rotary pin hoops inside are opened at one end of the rotary pin closed to the inside of the Y-shaped mechanism; the rotary pin pressing ring is sleeved outside the rotary pin hoop; and the retaining ring for the shaft is arranged on the top of the rotary pin pressing ring. Compared with prior art, the level rotary provided by the invention adopts a flexible rotary pin to achieve the coupling between the cup and the pin; with degrees of freedom, the cup and the pin cannot be deadly blocked during raising and lowering; the problem due to secondarily mixing of the separated matters can be reduced; and the tensile strength can be improved as well.

Description

Technical field [0001] The invention relates to a horizontal rotor device, in particular to a horizontal rotor provided with a pin subassembly. Background technique [0002] The horizontal rotors of centrifuges in the prior art, such as 250ml, 500ml, 1000ml or even larger 2500ml centrifuge cups, are centrifuged by hanging grooves milled on both sides on the rotor pin. The previous technology rotor The pin is directly integrally formed with the horizontal rotor, and the hanging groove is hung on the pin. Sometimes the cup will be stuck in different degrees during the rising or falling phase of the operation, which causes the secondary confusion of separated items. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a horizontal rotor provided with pin components that increases the degree of freedom and tensile strength, and reduces the secondary confusion of products. [0004] The purpose of t...

AI Technical Summary

Problems solved by technology

[0002] The horizontal rotors of centrifuges in the prior art, such as 250ml, 500ml, 1000ml or even larger centrifuge cups with a capacity of 2500ml, are all centrifuged by hanging on the rotor pins through the hanging grooves milled on both sides. The pin is directly integrally formed with the horizontal rotor, and when the hanging groove is hung on the pin, sometimes there will be different degrees of jamming of the cup during the ascending or descending stage of operation, resulting in secondary confusion of separated items.
