a three-dimensional book

Abstract

The invention discloses a three-dimensional mechanism book. The courses of mechanical principles are abstract, and the display racks of mechanical principles are expensive and inconvenient to carry. The present invention includes a book clip, a four-bar linkage mechanism leaf board, a cam mechanism leaf board, a gear coincidence degree leaf board and a gear meshing law leaf board; the four-bar linkage mechanism leaf board, a gear coincidence degree leaf board and a gear meshing law leaf board all include Transparent film, top book frame, leaf mechanism, bottom plate, driving dial and driven dial, the top book frame is bonded to the bottom plate, and the leaf mechanism, driving wheel and driven dial are all arranged on the top book frame and driven dial Between the bottom plates, both the driving wheel and the driven wheel are hinged to the bottom plate, and the driving wheel is meshed with the driven wheel, and the transparent film is stuck on the top book frame, and one side of the driving wheel is exposed to the side of the page mechanism ; The driving dial of the page plate of the cam mechanism meshes with the driving dial, and the driving dial meshes with the driven dial. The invention turns abstract and complex knowledge points into three-dimensional mechanisms, which are intuitive and vivid.

Description

technical field

[0001] The invention belongs to the field of teaching tools and relates to textbooks, in particular to a three-dimensional mechanism book. Background technique

[0002] According to the survey, students in major colleges and universities generally respond that the mechanical principles courses are too abstract and difficult to understand in class, resulting in poor grades. Although in response to this problem, most engineering colleges and universities are equipped with mechanical principle mechanism exhibition racks for students to visit after school or when doing experiments, aiming to better serve students in learning mechanical principles courses. However, there are two defects in the display rack. On the one hand, the display rack is expensive, and one display rack needs tens of thousands of funds, and there are many mechanisms for mechanical principles, which increases the burden on schools and mechanical principles courses. On the other hand, the disp...
