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.

Embodiment

[0015] A horizontal rotor provided with a pin assembly, its structure is as follows figure 1 As shown, it includes a horizontal rotor body 5 and a pin assembly. The horizontal rotor body 5 is composed of four Y-shaped mechanisms that are evenly distributed and connected at the bottom. The center of the horizontal rotor body 5 is provided with a rotating shaft 6 . The pin subassembly is composed of the swivel pin 4, the swivel pin hoop 3, the swivel pin pressure ring 2 and the shaft retaining ring 1. The swivel pin 4 is set in the through hole on the branch on the upper part of the Y-shaped mechanism. , The diameter of the through hole is 15mm. The end of the rotor pin 4 close to the inner side of the Y-shaped mechanism is provided with two 2mm grooves, and a semicircular rotor pin hoop 3 is arranged in the groove, and the rotor pin pressure ring 2 is set on the rotor pin hoop 3 On the outer side of the shaft, the retaining ring 1 for the shaft is inlaid on the top of the turr...

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 assembly. Background technique [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. Contents of the invention [0003] The object of the present invention is to provide a horizontal rotor provided with a pin assembly that increases the degree of freedom and tensile strength and reduces secondary confusion of products in order to overcome the above-mentioned defects in the...
