Problems solved by technology
Therefore, in actual teaching, multiple laboratories are often set up, and each laboratory is equipped with a special test bench corresponding to different experimental directions to solve the above problems. However, this form of setting up laboratories separately not only takes up a lot of space, but also requires Equipped with various experimental benches, resulting in a great waste of teaching resources

For the track device of the mechanical experiment, the two sides of the table board are extended with a rotating shaft, and the two support plates are provided with first slide holes extending from both ends of the rotating shaft, and the table board is respectively provided with first sliding holes on both axial sides of the rotating shaft The moving plate, the second moving plate, the first moving plate and the second moving plate are respectively provided with fixed blocks on the side facing the table, the two fixed blocks are provided with grooves, and the first moving plate faces the side of the second moving plate A first rack is arranged on the top, and a second rack is arranged on the side of the second moving plate facing the first moving plate. The first rack and the second rack are arranged in parallel up and down. Between the first rack and the second rack A gear is meshed with each other, the axis of the gear is provided with a rotating shaft, and the end of the rotating shaft passing through the support plate is provided with a handle.
Description
technical field [0001] The invention relates to the field of experimental auxiliary teaching equipment, and more particularly to a laboratory table suitable for various physical experiments. Background technique [0002] In the process of physics teaching, in order to make the teaching work more intuitive and vivid and facilitate students' understanding, some physics experiments are usually carried out in combination with the teaching progress. Common physics experiments are divided into mechanics, optics, electricity, fluids and other directions. The experimental instruments and equipment required for experiments in different directions are different, and the environments required for experiments are also different. At the same time, the experimental instruments and equipment required for each experimental direction are not universal. When the equipment is mixed with each other, some safety factors need to be considered. For example, the precision of the instrument required...
