Biological experiment oscillation device for detecting speed limit by utilizing centrifugation

Abstract

The invention relates to the technical field of biological experiment equipment, and discloses a biological experiment oscillation device for detecting speed limit by using centrifugation. The biological experiment oscillation device comprises an output shaft, one end of the output shaft is fixedly connected with an oscillation shaft, the outer side wall of the oscillation shaft is fixedly connected with a detection ring and a speed limit ring, and the inner side wall of the detection ring is fixedly connected with a sliding rail; and one end of the sliding rail is fixedly connected with a detection base, and the inner side wall of the sliding rail is slidably connected with a centrifugal lead ball. When the oscillation speed is too high, the centrifugal force borne by the centrifugal leadball is increased, the pressure exerted by the centrifugal lead ball on an arc-shaped spring piece is larger than the elastic force of the arc-shaped spring piece, the surface of the arc-shaped spring piece is elastically deformed, the arc-shaped spring piece drives a trigger frame to move towards one side of an alarm device, the trigger frame triggers a switch on the alarm device, and thus the alarm device gives an alarm, so that an experimenter can know the oscillation state of a test tube in time, and the experimenter can conveniently adjust the device in time.

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vibration device for biological experiments using centrifugal detection to limit the speed, which has the advantages of real-time detection of the vibration speed of the test tube, and when the vibration speed is too fast, it will automatically limit or stop the vibration. It solves the problem that if the oscillation speed of the oscillation axis is too fast when the test tube is oscillated, the reagent in the test tube will generate a large centrifugal force, which will cause the denaturation of the reagent and affect the results of the biological experiment. In addition, the existing device does not have Problems with the function of high-speed vibration speed limit or protection for test tubes
