Experimental platform for chemical experiments for high school students

Abstract

The invention belongs to the technical field of chemical, and in particular, relates to an experimental platform for chemical experiments for high school students, wherein the experimental platform comprises a platform body; a supporting mechanism is fixedly connected at the lower end of the platform body, a lifting mechanism is arranged at the upper end of the supporting mechanism, and the upperend of the lifting mechanism is fixedly connected with the lower end of the platform body; the upper end of the platform body is provided with a storage mechanism and a cleaning mechanism; the storagemechanism and the cleaning mechanism are respectively arranged near the left edge and the right edge of the platform body; the upper end of the platform body is provided with a placement groove whichis located between the storage mechanism and the cleaning mechanism, and the bottom of the placement groove is fixedly connected with a supporting member; the upper end of the supporting member runsthrough a notch of the placement groove and extends to the outer side of the placement groove. The experimental platform has the advantages that unused and used chemical instruments are simply protected against being easy to break and overturn, and the height is adjusted at the same time so as to match students with different height to carry out chemical experiments, so that bodies are not easy tostiffen and ache during long-term experiments.

Description

technical field [0001] The invention belongs to the technical field of chemistry, and in particular relates to a laboratory bench for high school students' 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 chemical change and physical change in chemistry. [0003] Chemical experiments are an important form of learning and researching the subject of chemistry. Students can generally conduct routine chemical experiments in high school to learn chemistry better. The basis of chemical exp...

[0003] Chemical experiments are an important form of learning and researching the subject of chemistry. Students can generally conduct routine chemical experiments in high school to learn chemistry better. The basis of chemical experiments is chemical instruments. High school students A variety of chemical instruments are used to operate. Generally, the school is equipped with a special chemical experiment bench for use, but the general chemical experiment bench usually only has a flat desktop and a washbasin, and the students place it on the desktop. Various instruments are used to operate, facing unprofessional student groups, it is very easy to break the instruments in the laboratory, causing the chemical substances in them to disperse, and then pose a threat to students. At the same time, the existing chemical laboratory benches are usually The height cannot be adjusted. For students with different heights, some students whose heights do not match it will be extremely inconvenient during the experiment, and it is easy to cause errors in the experimental operation due to physical soreness.
