Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a magnetic remote combined physical mechanics experimental component group. Background Technique

[0002] Mechanics is a compulsory part of learning physics courses. As an important foundation of the physics discipline, it has a close relationship with many other disciplines (such as engineering, materials science, astronomy, etc.). There are many types of mechanics, including gravity, tension, elastic force, friction force, centrifugal force, etc. Since the concepts of mechanics are often somewhat abstract, teachers usually use various mechanics experimental teaching aids in the teaching process to help students more intuitively understand the basic concepts and principles of mechanics. These experimental teaching aids can enable students to deepen their understanding of the laws of mechanics through hands-on operations and observing experimental results. However, due to the large number of mechanics types, different experimental teaching aids also have their own characteristics in design and function. Taking the friction experimental teaching aid as an example, the existing teaching aids usually fixedly set an inclined slide on the experimental table, allowing the slider to slide along the slide, so as to conduct the experimental demonstration of friction. This fixed experimental setting restricts students' observation and understanding of the diversity of friction and its influencing factors to a certain extent and cannot meet different learning needs.

[0003] The patent with the publication number of CN210743346U discloses a teaching instrument for physical mechanics experiments, including an experimental table. A long strip-shaped slide plate is provided on the experimental table. One end of the slide plate is hinged to the experimental table, and the other end of the slide plate is provided with an adjusting mechanism for adjusting the angle of the slide plate. A protractor for measuring the angle of the slide plate is also provided on the experimental table. By adopting the technical solution in this patent, the angle of the slide plate on the experimental table can be adjusted through the adjusting mechanism, so that the experiment can be demonstrated on the slide plates at different angles, increasing the experimental conditions for the friction experiment demonstration and making the demonstration of this experiment more instructive.

[0004] Although in the prior art, by adjusting the angle of the sliding plate, the slider can be demonstrated on sliding plates at different angles, thereby increasing the experimental conditions for the friction force experiment demonstration and improving the flexibility and depth of teaching, there are still some deficiencies. First, since a pulling rope is tied to the slider, this will cause unnecessary interference when the slider slides, thereby affecting the accuracy and reliability of the experimental data. Second, when multiple sliders slide on multiple sliding plates with different surface friction coefficients respectively, it is impossible to ensure that the multiple sliders slide downward from the highest point simultaneously, thus affecting the effect of the experimental demonstration and the intuitiveness of teaching. To solve these problems, we propose a magnetic adsorption type remote combined physical mechanics experimental component group. This new type of experimental component group can not only eliminate the interference caused by the traditional pulling rope through magnetic adsorption connection and simultaneous release, but also enable multiple sliders to slide downward from the highest point simultaneously, providing a more rich and diverse experimental demonstration and improving students' understanding and application ability of mechanical principles.
