Abstract

The invention discloses a test tube rack for a chemical experiment and a use method of the test tube rack, and belongs to the technical field of teaching aids. According to the test tube rack for the chemical experiment and the use method of the test tube rack, the test tube rack comprises a bottom plate, a flow guide plate, a shaking device, a placing rack and a clamping piece; during the experiment, a test tube containing a solution is put back into a test tube guide opening, and the output end of a motor drives a connecting cap to rotate, so that a connecting shaft integrally formed with a connecting block rotates eccentrically, the flow guide plate shakes, the solution in the test tube is shaken up, and the experiment precision is improved; at the end of the experiment, the test tube is inserted upside down on a cleaning column, a pair of first air cylinders is started, and the movable ends of the pair of first air cylinders drive a rectangular frame to descend; a pair of second air cylinders is started, and the movable ends of the pair of second air cylinders are oppositely arranged; and the movable ends of the pair of second air cylinders clamp the side wall of the test tube to drive the test tube to rotate, water flow in the cleaning column flushes the interior of the test tube, meanwhile the test tube is rotationally cleaned at a hair brush, and the cleaning capability is enhanced.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, and in particular relates to a test tube rack for chemical experiments and a using method thereof. Background technique [0002] At present, with the continuous development of social economy, people pay more and more attention to education, and the teaching conditions are constantly improving. The test tube rack is a common experimental auxiliary device used in experiments. It is mainly used to place test tubes and observe certain experiments. phenomenon, or used to dry and clean test tubes. In the teaching process of chemistry, in order to facilitate students to better grasp chemical knowledge, corresponding chemical experiment teaching is generally carried out. In chemical experiment teaching, test tubes are the most commonly used Structure. [0003] The utility model whose publication number is CN211706864U discloses a kind of test tube rack for chemical experiments that can place...
