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...
