A Teaching Model of Rod Mechanism

Abstract

The invention discloses a rod mechanism teaching model, which comprises a box body, a manual rod transmission mechanism, a magic rail deformation mechanism and a guide rail moving mechanism. The invention is reliable in work, easy to operate, and can demonstrate any trajectory, including the example of typical rod mechanism used in real life, and can also demonstrate the centering and arbitrary offset crank slider mechanism; the production cost of the rod mechanism teaching model is reduced; The display cabinet placed in the laboratory is turned into a portable model that students can hold in their hands and explore by themselves; a set of models can demonstrate any trajectory after simple transformation, which is very interesting; it can stimulate students' ability to explore and innovate.

Description

technical field [0001] The invention relates to a teaching aid model, in particular to a teaching model which can enable students to correctly understand the rod mechanism and display the rod mechanism of any trajectory. Background technique [0002] The research results of pedagogical psychology show that in the initial stage of concept formation, students must rely on their senses, first transform the observation and contact of specific things into perceptual knowledge that has nothing to do with specific things, and then transform perceptual knowledge into abstract, generalized rational understanding. During the learning process, students should accept the achievements of human cognition in a relatively short period of time, laying a solid foundation for further understanding and transformation of the world. The achievements of human cognition are expressed by many concepts. Among the students whose main mode of thinking is image thinking, it is not enough to rely on th...

Problems solved by technology

[0003] The existing rod mechanism teaching model has many disadvantages in use: 1. The movement trajectory is not intuitive; 2. The rod can only be a fixed-length straight rod; 3. A set of devices can only demonstrate a single mechanism; Can be placed in the laboratory; 5. Expensive

To sum up, the existing cumbersome and expensive rod mechanism teaching model showcases can only be placed in the laboratory after they are purchased, and cannot be brought to the classroom for students to play with by themselves

The solution of the existing technical solution is to use a telescopic rod to combine two rods into one to change the length of the rod, but such a technical solution is cumbersome to operate, the teaching effect is not significant, and it still cannot solve the problems of power input, trajectory demonstration, and crank slider offset. And other issues

More importantly, these inflexible straight rod forms cannot allow students to fully and deeply understand rods and rod mechanisms, and even develop the mindset that rods can only be straight
