Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: 1. lack of cooperation of geometric teaching aids, unable to realize the teaching needs of spatial three-dimensional geometry; Not intuitive enough; 3. The adjustment direction is single, and the assembly of projected objects is relatively complicated, and the assembly during teaching is a waste of teaching time. A geometric teaching aid for mechanical drawing with folding storage function is proposed

Abstract

The invention discloses a geometric teaching aid for mechanical drawing with the function of folding and storing, and relates to the technical field of mechanical drawing teaching aids, including a base, an adjustment mechanism is provided on the top of the base, and a teaching aid body is movably connected to one side of the adjustment mechanism. One side of the adjustment mechanism is slidably connected with a projection mechanism, and both sides of the top of the base are fixedly connected to side plates, and a number of cover plates are hinged on the top of the base, and the cover plates are attached to the side plates on both sides. The adjustment mechanism includes a first As for the slider, a first sliding slot is opened on the top of the base. In the present invention, by setting the teaching aid mechanism, the first sliding rod slides and pulls the limit magnetic ring to separate from the third magnet, and the clamping seat rotates and offsets to adjust different geometric teaching aid body orientations, and the base and the external drawing paper can be attached directly through the teaching aid body Drawing pictures can significantly improve the installation adaptability of different geometric teaching aids, reduce the difficulty of assembly, effectively reduce the difficulty of mechanical drawing teaching, and meet the overall use needs.

Description

technical field [0001] The invention relates to the technical field of mechanical drawing teaching aids, in particular to a geometric teaching aid for mechanical drawing with the function of folding and storing. Background technique [0002] Mechanical drawing is a discipline that uses drawings to accurately represent the structural shape, size, working principle and technical requirements of machinery. Drawings are composed of graphics, symbols, words and numbers, and are technical documents that express design intentions, manufacturing requirements and exchange experience. In teaching, it is convenient for students to understand the spatial correspondence and mapping relationship of mechanical drawing. It is generally necessary to use geometric teaching aids to explain the teaching content, and to assist the purpose of drawing through teaching aids. [0003] The Chinese patent literature publication number is: CN210895898U patent discloses a kind of demonstration teaching ...
