Problems solved by technology

During the centrifugation experiment, the centrifuge tube is placed obliquely in some centrifuge machines. When the test tube is taken out by hand, the vibration and direction change will cause the layered and deposited substances to mix again, resulting in inaccurate experimental data. At present, there is an urgent need for a method that can be used to extract Shock-absorbing buffer device for centrifuge tube

Embodiment 1

[0031] Such as Figure 1-5 As shown, it is the multi-directional shock-absorbing and buffering device for the centrifuge tube in the extraction centrifuge of this embodiment, which includes an upper fixing plate 1 and a lower installation platform 2 that are arranged correspondingly to each other. Several groups of hydraulic shock absorbers 3, the length of the hydraulic shock absorbers 3 is 14~16cm, the upper end of the upper fixing plate 1 corresponding to each hydraulic shock absorber 3 is provided with an upper mounting assembly, and the lower mounting platform 2 corresponds to each hydraulic shock absorber The lower end of the device 3 is provided with a lower installation assembly, the upper part of the upper fixed plate 1 is provided with a grip handle 4, and the middle part of the lower side of the lower installation platform 2 is provided with an air pipeline 5, and the air pipeline 5 communicates with the air hose 6. The upper end of the gas delivery hose 6 is arrang...

Embodiment 2

[0045] Such as Image 6 , and the difference with embodiment 1 is: hydraulic shock absorber 3 is provided with two groups, and two groups of hydraulic shock absorber 3 are left and right symmetrically distributed, and hydraulic shock absorber 3 is set with spring one 9, and hydraulic shock absorber 3 The upper and lower ends of the upper and lower mounting components are respectively hinged with the ball joints of the upper mounting component and the lower mounting component. Hydraulic shock absorber 3 selects the car model shock absorber of full-length about 15cm for use, and the two ends of spring one 9 are stuck in shock absorber two ends, make hydraulic shock absorber 3 when not stressed, the microhydraulic shock absorber 3 The damping piston stays in the middle of the stroke of the shock absorber. When the damping piston deviates from the middle of the stroke of the shock absorber, the spring one 9 will be stretched or contracted to generate a force in the opposite direct...

Embodiment 3

[0047] Such as Figure 7 , the difference from Embodiment 1 is that: the hydraulic shock absorber 3 is provided with three groups, the hydraulic shock absorber 3 is provided with a spring one 9, and the upper ends of the three groups of hydraulic shock absorber 3 are distributed at equal intervals along the circumferential direction and The upper installation assembly is hinged with the ball joint, and the lower ends of the three groups of hydraulic shock absorbers 3 are all arranged near the center of the lower installation platform 2 and are hinged with the lower installation assembly with the ball joint. Three sets of hydraulic shock absorbers 3 make the upper fixing plate 1 and the lower installation platform 2 form a stable connection relationship.

Abstract

The invention discloses a multidirectional shock absorbing and buffering device for extracting a centrifugal tube in a centrifugal machine and a using method of the multidirectional shock absorbing and buffering device in the field of shock absorbing and buffering equipment. The multidirectional shock absorbing and buffering device comprises an upper fixing plate and a lower mounting platform, a plurality of sets of hydraulic shock absorbers arranged between the upper fixing plate and the lower mounting platform, a gas conveying pipeline is arranged in the middle of the lower side of the lower mounting platform, an air charging connector is arranged at the lower end of the gas conveying pipeline, a balloon is mounted on the air charging connector, an air inlet opening of the balloon corresponds to the periphery of the air charging connector, a compacting shock absorbing mechanism for tightly pressing the balloon is arranged corresponding to the balloon, and a jacket for clamping a centrifugal tube to be extracted is connected to the lower mounting platform. The method comprises the following steps that a compacting sleeve tightly presses the opening part of the balloon on the air charging connector, the shriveled balloon correspondingly extends into the centrifugal tube to be extracted, the balloon expands to be attached to the inner wall of the centrifugal tube, the centrifugal tube is slowly lifted, and the centrifugal tube is placed on a test tube rack. The centrifugal tube can be stably extracted, and layered and deposited substances in the centrifugal tube are prevented from being mixed again.

Description

technical field [0001] The invention belongs to the field of shock absorbing and buffering equipment, in particular to a multi-directional shock absorbing and buffering device for extracting centrifuge tubes in a centrifuge and a use method thereof. Background technique [0002] In the fields of material science, biochemistry and molecular biology research, centrifuges have been widely used, and each material science, biochemistry and molecular biology laboratory must prepare various types of centrifuges. Centrifugal technology is mainly used for the separation and preparation of various substance samples. The sample suspension is placed in a centrifuge tube under high-speed rotation. Due to the huge centrifugal force, different substances settle at a certain speed, thus making each substance layered. deposition. [0003] In the prior art, hydraulic shock absorbers are widely used in various machines that generate vibrations during operation to buffer the vibrations. The h...
