A laboratory bench for chemistry experiments for high school students

Abstract

The invention belongs to the technical field of chemistry, and in particular relates to an experimental platform for high school students' chemical experiments, which comprises a platform body, a support mechanism is fixedly connected to the lower end of the platform body, a lifting mechanism is provided at the upper end of the support mechanism, and the upper end of the lifting mechanism is connected to the platform body. The lower end of the table body is fixedly connected, the upper end of the table body is respectively provided with a storage mechanism and a cleaning mechanism, and the storage mechanism and the cleaning mechanism are respectively arranged near the left and right ends of the table body. Between the cleaning mechanisms, the bottom of the placement tank is fixedly connected with a support, and the upper end of the support passes through the notch of the placement tank and extends to the outside. The advantage is that the present invention can simply protect unused and in-use chemical instruments so that they are not easy to be broken and knocked over, and at the same time, the height can be adjusted so that students of different heights can be matched for chemical experiments, so that they can be During long-term experiments, the body is not easy to be stiff and sore.

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.
