Description
Technical field
The utility model relates to a kind of machinery class teaching aid, is specifically related to a kind of mechanical drawing three-view diagram projection teaching aid.
Background technology
In modern industry is produced, machinery, chemical industry or building all carry out manufacturing and constructing according to pattern. Planner is intended to by pattern design of expression, and producer understands design requirements by pattern, tissue manufactures and Instructing manufacture, it may also be useful to person understands the stuctures and properties of machinery equipment by pattern, carries out operating, maintenance process simulation. Therefore machinery pattern is that technical intelligence, the medium of thought and instrument are transmitted in exchange, is the technical language that engineering circle is general. Therefore, Ge great colleges and universities all arrange this course of mechanical drawing, by the training to technician so that it is learn and grasp this kind of language, possess the basic ability of recognition and drawing mechanical graphics.
In Graphing of Engineering, it is often necessary to three-dimensional body 2-d plane graph is expressed on paper, usually realizes this purpose by sciagraphy. And when Mechanical Drawing Taught is given lessons, teacher often adopts the projection figure on single picture to express sciagraphy, image not, student is difficult to understand process and the principle of projection. In prior art, there is the teaching aid that some express sciagraphy, but usually designed teaching aid structure is too complicated so that teacher carries inconvenience, and some teaching aids location is incorrect, cause projection view to be expressed inaccurate, it is easy to mislead students.
Practical novel content
The utility model provides a kind of structure simple, is convenient to carry, and can accurately locate, and ensures the mechanical drawing three-view diagram projection teaching aid that projection is correct.
The utility model adopts following technical scheme:
A kind of mechanical drawing three-view diagram projection teaching aid, comprise base, base bottom is provided with storage chamber, storage chamber top is provided with light-source chamber, described storage chamber and light-source chamber are spaced from each other, light source drawer it is provided with in light-source chamber, light source drawer is provided with at least one guide path, tail rod it is provided with in guide path, tail rod is connected with parallel light source, light source drawer is also provided with placed cavity, support it is provided with above base, support is provided with glove plate, also it is provided with at least one above base and groove is installed, groove is installed and is parallel to chassis side, install in groove and it is plugged with projection plate, projection plate is perpendicular to base upper surface.
On described glove plate draw have many standard liness, standard lines is parallel to projection plate, or is perpendicular to projection plate, or with projection plate at an angle. Placing when needing projected objects on glove plate, usable criterion line compares, and finds accurately and places position, to obtain correct projection view.
Preferably, described support with base for being flexibly connected, for convenience detach, and by swinging mounting glove plate is arranged to the angle that needs, usually by Bracket setting heart position in the base, with the projection facilitating object whole.
In order to facilitate taking out of light source drawer to draw, described light source drawer is provided with handle.
Advantage of the present utility model and useful effect be:
1, the compact construction that the utility model adopts, parallel light source can be pulled down after projection and put into placed cavity, then projection plate, tail rod, glove plate and support are pulled down respectively and put into storage chamber, again light source drawer is pushed away in light-source chamber, it is a rectangular structure that entirety can be concluded, it is scattered without independent part, easy to carry.
2, on the utility model glove plate, drafting has many standard liness so that having the normal place of comparison when object is placed, thus reach the object of accurate projection, meanwhile, teacher can project the project objects wanting angle by reference standard line.
3, the utility model guide path and tail rod structure make the distance of parallel light source and object adjustable, easy to use.
The view that what 4, the utility model can be vivid show after 3 D stereo projects, simple and practical, it is convenient to student and understands.
