Problems solved by technology

Some of the existing teaching aids have a single function and an overly complex structure. They have not gotten rid of complicated and boring theories, and cannot significantly improve the efficiency of teaching.
[0003] Chinese patent CN201984710U introduces a demonstration teaching aid for the principle of a hinged four-bar mechanism. Although the teaching aid can intuitively display three different types of hinged four-bar mechanisms, the display process only reflects the operation process of the mechanism, and has not been realized. The combination of the "Principles of Mechanics" cannot change the boring nature of the course itself, so it is difficult to achieve good teaching results
Chinese patent CN103514796A introduces a crank-rocker mechanism demonstration teaching aid for teaching. Although the teaching aid simulates the scene of a pirate ship in an amusement park, it can increase interest to a certain extent, but the function of the teaching aid is too single, the scope of application is narrow, and it is economical. poor
Although the teaching aids described in these two patents are all multi-functional teaching aids, which can display various mechanical structures and different knowledge points, their structures are relatively complicated and their intuition is poor.

Description

technical field [0001] The invention relates to a mechanical principle demonstration teaching aid, in particular to a multifunctional mechanical principle demonstration teaching aid. Background technique [0002] With the rapid development of China's industrialization, especially the development of manufacturing industry, the society's demand for talents with mechanical related majors is increasing. "Mechanical Principles" is one of the most important main courses of mechanical majors. The teaching work of this course is of great significance, so appropriate teaching aids are needed as an auxiliary. Some of the existing teaching aids have a single function and an overly complex structure. They have not got rid of complicated and boring theories, and cannot significantly improve the efficiency of teaching. [0003] Chinese patent CN201984710U introduces a demonstration teaching aid for the principle of a hinged four-bar mechanism. Although the teaching aid can intuitively di...
