Description

Ultrasonic cell disruption instrument Technical Field The utility model relates to the technical field of cell disruption, in particular to an ultrasonic cell disruption instrument. Background The ultrasonic cell disruption instrument converts electric energy into acoustic energy through a transducer, the energy is changed into dense small bubbles through a liquid medium, the small bubbles are rapidly exploded, and the generated energy is like a small bomb, so that the cell disruption instrument plays a role in breaking substances such as cells. When the cell disruption instrument in the prior art is used, the bearing cylinder is generally placed in the generation box, the amplitude transformer is inserted into the bearing cylinder to be disrupted, but in actual operation, the high-frequency vibration of the amplitude transformer can drive the bearing cylinder to vibrate, the bearing cylinder can vibrate and have the risk of toppling, the toppling bearing cylinder can lead to cell scattering, the experimental process and the result are influenced, part of cells can be splashed by the high-frequency vibration of the bat rod, the part of splashed cells can splash out of the bearing cylinder, not only sample loss is caused, but also the follow-up cleaning is more troublesome. Disclosure of utility model The utility model aims to solve the problems in the background art and provides an ultrasonic cell disruption instrument. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides an ultrasonic cell disruption appearance, includes shell and transducer main part, transducer main part fixed connection is on the interior roof of shell, be connected with the amplitude transformer on the driving end of transducer main part, still include: The positioning sleeve is fixedly connected in the shell and is positioned right below the amplitude transformer, and the positioning sleeve is used for placing the bearing cylinder; When the electric push rod pushes the limiting plates to move, the two groups of limiting plates are attached to each other, and the inner side walls of the limiting plates are propped against the side walls of the bearing cylinder. Preferably, the limiting plate is fixedly connected with a supporting rod, the supporting rod is fixedly connected with a baffle, and when the limiting plate drives the baffle to move, two groups of baffles are attached to each other. Preferably, the two groups of limit plates which are symmetrically arranged are fixedly connected with first magnets, and the two groups of first magnets attract each other. Further, the two groups of baffle plates which are symmetrically arranged are fixedly connected with second magnets, and the two groups of second magnets attract each other. Preferably, the positioning sleeve is a rubber sleeve, and the positioning sleeve is provided with a mounting groove, and the diameter of the mounting groove is smaller than or equal to the diameter of the bearing cylinder. Further, a rubber anti-slip pad is fixedly connected to the inner side wall of the limiting plate. Compared with the prior art, the utility model provides an ultrasonic cell disruption instrument, which has the following beneficial effects: The utility model pushes the limiting plates to move through the symmetrically arranged electric push rods, the two groups of limiting plates are propped against the side wall of the bearing cylinder when being attached, meanwhile, the inner side walls of the limiting plates are provided with rubber anti-slip pads, the friction force between the two groups of limiting plates and the bearing cylinder is increased, and the first magnets attracted on the limiting plates are combined, so that the connection stability between the limiting plates is improved, stable and reliable clamping of the bearing cylinder is ensured by multiple measures, the bearing cylinder is prevented from being toppled over in high-frequency vibration of cell breakage, and cell scattering is avoided.
