Mechanical principle experiment teaching aid

Abstract

A mechanical principle experiment teaching aid comprises a lower box body, a middle rotation device, an upper box body, a display plate, a demonstration teaching aid and a differential. The middle rotation device is arranged on the top part of the lower box body. The middle rotation device is capable of rotating around a vertical axis thereof. The upper box body is arranged on the middle rotation device. The display plate is arranged on the outer surface of the upper box body. The demonstration teaching aid is arranged on the display plate. The differential is arranged in the upper box body. The differential is provided with a transmission shaft. The transmission shaft extends out from the upper box body to be connected with the demonstration teaching aid. The transmission shaft provides power to the demonstration teaching tool. According to the invention, the differential is arranged in the upper box body, and the transmission shaft on the differential extends out from the upper box body to be connected with the demonstration teaching aid. Power is conveniently provided by the transmission shaft, and the movement of a mechanical mechanism is visually demonstrated, so that students are enabled to visually understand the movement rule of the mechanism and rapidly understand the movement relations among members while learning a mechanical principle course, and the understanding to machinery is deepened.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a mechanical principle experiment teaching aid. Background technique [0002] In terms of current teaching, my country's education blindly focuses on test scores and ignores students' understanding and hands-on ability. In the teaching process, there is a lack of teaching tools for actual demonstration. The lack of teaching tools makes teaching a boring language description. Teaching aids are objects for the purpose of disseminating science and technology and educating people. They are complete technological media and indispensable equipment for young people's scientific and technological activities. The teaching aids used in scientific and technological activities include physical teaching aids and replica teaching aids. The teaching aids of these three important educational stages of junior high school, senior high school and university are very scarce at present, and th...
