Problems solved by technology

[0002] Test tubes are commonly used tools in chemistry teaching. When performing chemical reaction experiment demonstrations, teachers generally operate them. In most cases, teachers hold test tubes for demonstration. When hands slip or students touch them, it is easy to drop the test tube, causing Damage, serious damage to the health of teachers and students
The existing test tube rack only has the simple function of placing test tubes, so it is necessary to design a test tube rack to facilitate teaching and display

Abstract

The invention relates to the technical field of teaching aids and particularly relates to a test tube stand for teaching demonstration. The test tube stand comprises a base, a rotary shaft, an arc-shaped plate and a bracket. According to the test tube stand for teaching demonstration, provided by the invention, by the arc-shaped plate, self-alignment is carried out by using gravity of test tubes and a centrifugal action; a lighting lamp is further arranged on the arc-shaped plate, so as to enhance a demonstration effect; the rotary shaft is arranged at the bottom of the test tube stand and is inserted into the base, so that multi-angle flexibility is improved; and the base is hollow and can also be used for placing the test tubes.

Description

Technical field [0001] The invention relates to the technical field of educational equipment, in particular to a test tube rack for teaching demonstration. Background technique [0002] Test tubes are commonly used tools in chemistry teaching. When performing chemical reaction experiment demonstrations, they are generally operated by teachers. In most cases, teachers hold test tubes for demonstration. When hands slip or students touch, it is easy to drop test tubes, causing Damage to the health of teachers and students in severe cases. The existing test tube rack only has a simple function of placing test tubes, and it is necessary to design a test tube rack to facilitate teaching and display. Summary of the invention [0003] (1) Technical problems solved [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a test tube rack for teaching demonstration, which is convenient for teaching demonstration. [0005] (2) ...
