Safety protection device for chemical experiment

Abstract

The invention discloses a safety protection device for a chemical experiment. The safety protection device comprises an experiment table; a protective cover lifting mechanism which is mounted at the top of the experiment table; two adjustable support assemblies which are installed at the left end and the right end of the rear side of the top end of the experiment table respectively; an automatic dumping mechanism which is fixedly mounted at the top of the adjustable support assembly on the left side; a glass rod clamp which is fixedly mounted at the top of the adjustable support assembly on the right side; and a beaker which is placed in the middle of the top end of the experiment table. According to the safety protection device for the chemical experiment, the protective cover can be controlled to move up and down, so that opening and closing of the protective cover are achieved, operation is easy, test agents splashed in the experiment process can be blocked, safety is extremely high, the test agents can be automatically poured, meanwhile, the positions and the angles of the small beaker and the glass rod can be quickly adjusted, so that the experimental reagent in the small beaker can be accurately poured on the outer wall of the glass rod.

Description

technical field [0001] The invention relates to the technical field of chemical experiment instruments, in particular to a safety protection device for chemical experiments. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and change laws of matter at the molecular and atomic levels; the science of creating new matter, the world is composed of matter, and chemistry is the main method for human beings to understand and transform the material world. One of the methods and means, it is a subject with a long history and full of vitality. Its achievements are an important symbol of social civilization. There are two forms of change in chemistry, chemical change and physical change. Chemistry is based on experiments. Observing the phenomenon in the experiment and summarizing the experimental data, it can be seen that the experiment is particularly important to the development of chemistry. In the exploration...
