Abstract

The invention discloses a classroom teaching aid for demonstrating mechanical drive, which belongs to the field of mechanical classroom teaching aids. The classroom teaching aid for demonstrating mechanical drive, the teaching aid includes: a loose-leaf ring buckle and a plurality of leaf devices installed on the loose-leaf ring buckle, and the book leaf device includes a transparent casing and a mechanical device installed in the casing The moving structure, the mechanical moving structure of each page device includes one or more of a power mechanism, a double crank mechanism, a double rocker mechanism, a crank rocker mechanism, a cam mechanism, and a gear mechanism. The classroom teaching aid driven by the demonstration machine provided by the present invention can run through a mechanical mechanism, so that the demonstration can move continuously. At the same time, the classroom teaching aid has a simple and ingenious structure and is easy to operate. At the same time, the teaching aid is fixed in a transparent box, which is convenient for visually observing the operation process of each mechanism, and is convenient for students to diverge their thinking and improve their innovation consciousness.

Description

technical field [0001] The invention relates to the field of mechanical classroom teaching aids, in particular to a classroom teaching aid for demonstrating mechanical drive. Background technique [0002] Mechanical classroom teaching aids are to demonstrate the movement form of machinery to students intuitively and help students understand the movement form of machinery. [0003] The existing mechanical classroom teaching aids are simple in structure, mostly through the simple combination of several parts, and the demonstration process is mostly completed manually by the teacher. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Since the demonstration process is mostly done manually, sometimes the mechanical classroom teaching aids cannot demonstrate its movement continuously and smoothly, which is not conducive to students' understanding of the movement form reflected b...
