Description
Technical field
This utility model belongs to primary school teaching apparatus field, relates to a kind of primary school mathematics three-view diagram instructional device.
Background technology
Modern mathematics requires that we observe the world by the eye of mathematics, illustrates the world with the language of mathematics.From the point of view of pupil's mathematics learning psychology, student learning process is not passive absorption process, but the process of a construction again based on existing knowledge and experience, therefore, learning by doing, play middle school, abstract mathematical relationship is converted in student life the example being familiar with, child will be made to learn more initiative.From the point of view of our educational objective, we are while teaching knowledge, more answer the observation of attention to training student, analyze and the integration capability such as application.
Three-view diagram can correctly reflect that the orthographic projection engineering drawing (front view, top view, three basic views of left view) of object length size is three-view diagram, and this is a kind of abstract expression mode sanctified by usage to geometry of objects of engineering circles.
In current primary school, the teaching method for three-view diagram is divided into two kinds substantially, and one is material object will to be utilized to be shown, and then teacher draws three-view diagram on blackboard, and another kind draws axonometric chart on blackboard, draws three-view diagram the most again.All there is bigger limitation in both modes, the first can be observed by good carrying out, but operation more bothers.The second bothers equally, and requires higher to the third dimension of student.Three-view diagram instructional device currently without a kind of intuitive and convenient.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, providing a kind of primary school mathematics three-view diagram instructional device, this primary school mathematics three-view diagram instructional device smart structural design, teaching efficiency is good, solve the problems such as existing three-view diagram teaching method existing defects, teaching efficiency difference.
nullThe purpose of this utility model can be realized by following technical proposal: a kind of primary school mathematics three-view diagram instructional device，It is characterized in that: described instructional device includes in cylindrical mounting post，Described mounting post upper end is rotatably connected to erect the rotation bar arranged，The lower end of described rotation bar is rotatably connected in described mounting post，The upper end of described rotation bar is fixed with in block mounting blocks，One end of described mounting blocks has the installing plate of protrusion，The rotary column of horizontally set it is rotatably connected on described installing plate，Described rotary column runs through described installing plate，One end of described rotary column is fixed with the latch being rectangle，The other end of described rotary column is fixed with L-shaped handle，Three view component it are fixed with on described mounting blocks，Described view component includes the view frame in " Jiong " font，Described view frame lower end is fixed on described mounting blocks，The view plate of connected promising stretching structure in described view frame，Drawing is posted on described view plate.
The substantially use process of this instructional device is as follows: fixing by realizing in the insertion latch in kind of teaching, be sticked on the view plate of front side the drawing of front view, be sticked on the view plate of sidepiece the drawing of side view, be sticked on view plate below the drawing of top view, when observing, position in kind can be adjusted by rotating bar, student is facilitated to carry out observing drawing, when carrying out in kind observation, the view plate making correspondence shrinks, and then allows student be observed by observation panel, very directly perceived, leave behind again after observation view plate, make student with deep impression.When carrying out the observation of top view, vertical view face in kind is rotated to rear by swing handle, and then rotary motion bar is observed by the observation panel of rear side, convenience very, and the design of this apparatus structure is ingenious, and effective to student instruction, visual angle is directly perceived.
In above-mentioned a kind of primary school mathematics three-view diagram instructional device, having bearing in described mounting post upper end, described rotation bar lower end is connected in described bearing.
Realize rotating being rotationally connected of bar by bearing.
In above-mentioned a kind of primary school mathematics three-view diagram instructional device, the bottom of described view plate is fixed with the pulling block of protrusion.
By pulling block is convenient, view plate is operated.
In above-mentioned a kind of primary school mathematics three-view diagram instructional device, the end of described handle has some anti-skidding burrs.
Facilitate teacher's manipulation to handle.
Compared with prior art, this primary school mathematics three-view diagram instructional device has the advantage that
1, this primary school mathematics three-view diagram instructional device smart structural design, teaching efficiency is good.
2, when this primary school mathematics three-view diagram instructional device is observed, position in kind can be adjusted by rotating bar, student is facilitated to carry out observing drawing, when carrying out in kind observation, the view plate making correspondence shrinks, and then allows student be observed by observation panel, very directly perceived, leave behind again after observation view plate, make student with deep impression.
