Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of experimental platforms, and particularly relates to an electronic circuit experimental platform. Background Art
[0002] When students are learning electrical related content, in order to combine theory with practice and improve learning effects, they are often led to conduct corresponding electronic circuit experiments, so they often use corresponding electronic circuit experimental tables. During the growth period, students have different heights due to various factors, especially between male and female students, but most common electronic circuit experimental tables are fixed height mechanisms, and the height of the experimental table cannot be adjusted according to the height of the students. As a result, taller students need to bend over to conduct electronic circuit experiments, which will have an adverse effect on growing students over time.
[0003] Secondly, students who develop relatively slowly are relatively short in height and may need to stand on tiptoe to conduct related electronic circuit experiments on the laboratory table. In experiments involving electricity, they may fall due to unstable center of gravity, which may lead to related equipment or wires being pulled, resulting in electric shock accidents and endangering the students' lives and health.
