Abstract

The utility model provides a three-view projection demonstration mold, belonging to the geometry teaching technical field. The three-view projection demonstration mold comprises a demonstration mold and a projection model. The demonstration mold is formed by templates and hinges. The templates are three squares with a same size. The templates are fixed through the hinges. The templates are perpendicular to each other. The projection model is a plurality of independent model entities and is placed on the demonstration mold. According to the three-view projection demonstration mold, a three-view drawing principle can be demonstrate well, understanding and memory are facilitated, manufacture of the three-view projection demonstration mold is simple, cost is low, students can make the three-view projection demonstration mold by themselves, and while learning efficiency is raised, spatial thinking ability can be strengthened.

Description

The Three-view projection demonstration mould

Technical field

The utility model relates to the teaching mould field, is specifically related to a kind of Three-view projection demonstration mould.

Background technology

Carrying out along with the reform in education, more and more wide to parts three viewes projection teaching face, generally all be that teacher uses the mode of plan Drawing to student explain three-view diagram knowledge at blackboard at present, for rigidly connecting the student who touches solid geometry, just begun the thinking that brain sometimes can't form space structure, gruelling when removing to imagine its sterogram from three-view diagram, do not understand these figures are how to be developed by solid figure, form confusion of thinking, do not catch up with thinking and rhythm that teacher teaches.Although school with good conditionsi begins to adopt projector, can reflect preferably three-view diagram drawing principle like this, the projector price is not low, and general school is difficult to be equipped with, and does not have popularization.

The utility model content

Technical problem to be solved in the utility model is to provide Three-view projection demonstration mould a kind of simple in structure, with low cost.

Technical problem to be solved in the utility model realizes by the following technical solutions,

A kind of Three-view projection demonstration mould, comprise demonstration mould and projection model, described demonstration mould is comprised of template and hinge, described template is the identical squares of three block sizes, described template is fixed by hinge, mutually vertical between the described template, described projection model is several independently model entities, and described projection model is placed on the demonstration mould.

The beneficial effects of the utility model are: the utility model can well be demonstrated the three-view diagram map-making principle, be convenient to understand and memory, and make simple, with low cost, can oneself make behind the students in class, can also strengthen spatial thinking ability when improving learning efficiency.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

A kind of Three-view projection demonstration mould, comprise demonstration mould 1 and projection model 2, described demonstration mould 1 is comprised of template 3 and hinge 4, described template 3 is the identical squares of three block sizes, and described template 3 is fixing by hinge 4, and is mutually vertical between the described template 3, described projection model 2 is several independently model entities, described projection model 2 is placed on the demonstration mould 1, will demonstrate respectively so the three-view diagram of projection model 2 on three templates, i.e. front view, left view and vertical view.

Above demonstration and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. Three-view projection demonstration mould, comprise demonstration mould and projection model, it is characterized in that: described demonstration mould is comprised of template and hinge, described template is the identical squares of three block sizes, described template is fixed by hinge, mutually vertical between the described template, described projection model is several independently model entities, and described projection model is placed on the demonstration mould.
