A multi-functional mechanical principle display teaching aid

Abstract

The invention provides a multifunctional mechanical principle display teaching aid, relating to a mechanical principle display teaching aid. The multifunctional mechanical principle display teaching aid is provided with a crank rocker mechanism, a waterwheel, a bottom plate, a waterwheel transmission shaft, a vertical bevel gear, a horizontal bevel gear, a bevel gear shaft, a belt wheel, a grinding disc, a grinding disc base, a driven crank, a driving crank, a double-crank connecting rod, a double-rocker mechanism, a baffle plate, a disc cam, a cam shaft, a sieve disc, a speed changer, a well, a left supporting frame, a right supporting frame, a handle, a ratchet wheel, a ratchet pawl, a spring, and a vertical plate. The double-rocker mechanism is provided with a driving rocker, a driven rocker, and a double-rocker connecting rod. The speed changer is provided with an upper transmission shaft, a power cam shaft, a power input shaft and a speed changing handle. The crank rocker mechanism is provided with a connecting rod, a driven rod, a driving rod, a blender, a ramming tank, and a support frame. The multifunctional mechanical principle display teaching aid has the advantages of abundant functions and simple and reasonable structure, the simplification of the complicated mechanical knowledge can be realized, the abstract theory becomes concrete and vivid, the boring content becomes interesting, and the teaching effect is effectively improved.

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...

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.
