Abstract
A novel machinery drawing three-view drawing projection teaching aid belongs to the machinery drawing teaching aid field; a conventional teaching mode employs a paper made three-view drawing model or a projection model with a simple structure to carry out lecture teaching, a teaching process is boring without perceptual knowledge, so teaching effect is poor. The novel machinery drawing three-view drawing projection teaching aid comprises a connecting rod, a cross joint, an organic glass plate, a light mobile guide rod, a light mounting pedestal, a light mounting rod, a projection lamp and a locking screw nut; a teacher can directly, vividly and conveniently tell a projection relation of a projection image, students can easily understand and remember, so the novel machinery drawing three-view drawing projection teaching aid is good in teaching effect.
Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to novel mechanical drawing Three-view projection teaching aid used in a kind of mechanical drawing teaching and study.
Background technology
Machinery industry is the traditional industries of China, at present, and in the mechanical drawing three-view diagram teaching of the machinery of national all kinds of vocational technical universities and colleges and skilled workers school and mechanical relevant speciality.Substantially be that teacher adopts three-view diagram model made of paper or the single projection model of structure to carry out instruct teaching, teaching process is quite uninteresting, lack perceptual knowledge, Self-Understanding and the oneself's imagination that can only depend on student, its result finally causing is to have affected the quality of instruction of Mechanical Drawing Taught, and three-view diagram is open the door brick and the cornerstone of mechanical drawing study, once this content is not succeeded in school, will have influence on the systematic learning of course below, make student lose the interest of study.
Utility model content
The purpose of this utility model is intended to overcome in existing machinery drawing teaching process, exist teaching process dry as dust, the problems such as efficiency of teaching is low, provide a kind of teacher can tell about intuitively, vividly, easily the projection relation of perspective view, student is understandable, easily memory, the novel mechanical drawing Three-view projection teaching aid that teaching efficiency is good.
For this reason, the utility model is by the following technical solutions: novel mechanical drawing Three-view projection teaching aid, it is characterized in that, described novel mechanical drawing Three-view projection teaching aid comprises connecting link, cross connector, poly (methyl methacrylate) plate, light mobile guide bar, light mounting seat, light mounting rod, Projecting Lamp and set nut; Described cross connector and connecting link respectively have eight, and the two ends of connecting link are respectively set in the endoporus of two cross connectors, assemble so successively, form a square casing; Described organic glass has three, is plugged in respectively in three slots on adjacent connecting link, forms H, V, tri-projecting planes of W; Described light mobile guide bar is set on two cross connectors in dead ahead on projecting plane, and light mounting seat is threaded onto on light mobile guide bar, can move freely; Described light mounting rod is threaded onto in the center pit of light mounting seat, can according to light height need free adjustment height, locked by set nut; Described Projecting Lamp is fixedly installed in light mounting rod top.
As to technique scheme supplement and perfect, the utility model also comprises following technical characterictic:
Described light mobile guide bar has two;
Described cross connector four direction respectively has connection endoporus;
On eight described connecting links, all offer slot;
When the utility model uses, by the novel mechanical Three-view projection teaching aid that charts, be placed on the desktop of dais, on two blocks of organic glass therein, post projection paper, projection thing is placed on an other organic glass, open Projecting Lamp, be irradiated in object, projection thing reflects by being projected in the projection paper on organic glass like this.Take off projection paper.
Use the utility model can reach following beneficial effect: the utility model is simple to operate, lively directly perceived, facilitate teacher to tell about the projection relation of project objects figure.
