Example Embodiment

[0042] Example 1

[0043] Such as figure 1 , figure 2 as well as image 3 As shown, the physics experiment teaching demonstration model includes a base 1, on which a first support board 15, a second support board 4, a third support board 3, and a fourth support board 2 are fixed along the vertical direction. A rotating shaft 7 is provided between the supporting plate 4 and the fourth supporting plate 2. One end of the rotating shaft 7 penetrates through the wall of the fourth supporting plate 4 and is connected with a rotating handle 8. An experiment table 6 is fixed on the rotating shaft 7 The upper surface of 6 is provided with a first mechanics demonstration mechanism 10 and a first free-fall demonstration mechanism 9, and the lower surface of the experimental platform 6 is provided with a second mechanics demonstration mechanism 11;

[0044] Such as Figure 4 As shown, the first mechanics demonstration mechanism 10 includes a bottom plate 101. The bottom surface of the bottom ...

Example Embodiment

[0049] Example 2

[0050] This embodiment is further optimized on the basis of embodiment 1. Specifically, the electromagnet fixing device 103 includes an electromagnet, a switch 1032 that can control whether the electromagnet is energized, and an electromagnet chuck 1031. The electromagnet is connected to Mains connection, when in use, the switch is turned on, the electromagnet is energized, and the electromagnetic chuck 1031 will adsorb and position the magnetic test block. During the demonstration, rotate the handle and close the switch at the same time. The magnetic test block slides on the inclined plate 102, and the inclined plate 102 is lifted up , Students can observe the experiment intuitively.

Abstract

The invention discloses a physical experiment teaching demonstration model. The physical experiment teaching demonstration model comprises a base, a first supporting plate, a second supporting plate,a third supporting plate and a fourth supporting plate are fixedly arranged on the base in the vertical direction, a rotary shaft is arranged between the second supporting plate and the fourth supporting plate, and one end of the rotary shaft penetrates through the wall part of the fourth supporting plate to be connected with a rotary handle. The rotary shaft is fixedly provided with an experimenttable, a first mechanics demonstration mechanism and a first free-fall demonstration mechanism are arranged on the upper surface of the experiment table, and a second mechanics demonstration mechanism is arranged on the lower surface of the experiment table. A third mechanics demonstration mechanism is arranged on the second supporting plate. By means of the physical experiment teaching demonstration model, students can be made to have senses of participation, and experiments can be consistently demonstrated, the functions are powerful, and the practicability is high.

Description

technical field [0001] The invention relates to the field of teaching models, in particular to a demonstration model for teaching physics experiments. Background technique [0002] Experiment is a major branch of physics. In physics teaching, physics experiments run through elementary school, junior high school and even high school. In physics experiment teaching, teachers especially explain support force, friction force, pressure and force decomposition and state of motion. In the process, it is difficult for students to understand only by oral explanations. Only through live demonstrations by teachers and students' personal experiments can students have a deep memory and a thorough understanding. This requires a mechanical demonstration device for students that can be practically operated and demonstrated. [0003] Through retrieval, the application publication number is CN 106504620 A Chinese patent "a physical projectile experiment demonstration device", which includes a...
