Description
Technical field
A kind of teaching aid is the utility model is related to, specially a kind of solid geometry demonstrator.
Background technology
Clergy at school when, although complete teaching task with following the prescribed order, effect is unsatisfactory, Hen Duoxue
Life can produce the feared state of mind after finishing solid geometry, fear solid geometry, even result in the downslide of overall mathematics achievement.
Model plays important function served as bridge in the study of solid geometry and the culture of space imagination, and visual model is more
Specifically clear experience can be provided, it is the important component for learning solid geometry and training student space imagination.Work as
When raw manual fabrication model, the presentation of model is first formed in brain, then this image could be agglomerated to model
Manufacturing process in, student has naturally also just realized the visual pattern set up, and has so not only cultivated Students ' Learning and has stood
The interest of body geometry, creation and the space imagining ability of student have been cultivated again.New demonstrator is very easy, applicable in operation,
Positive effect.
Utility model content
The utility model provides a kind of solid geometry demonstrator, and the solid geometry demonstrator has demonstration convenient, vivid
And the advantages of easily making simple in construction.
To achieve the above object, the utility model provides following technical scheme：

Wherein, square plate bottom is equivalent to the bottom surface of polygon, and clergy can be by moving back and forth apparatus for demonstrating, and increase is stretched
Quantity of contracting bar etc., triangular pyramid, rectangular pyramid even polygonal pyramid are demonstrated to student so that classroom instruction is more vivid, learns
Life is easier to understand；
Meanwhile flexible demonstration bar connects with fixed column upset, easily facilitates the demonstration of clergy；And in flexible demonstration
After bar puts good position, mutually fixed by fixed sleeve part, student can be easy to pass round geometric figure, when not in use, can be by fixation
External member is dismantled, and is easy to store.
Preferably, the fixed column upper end is provided with the first hook, and accordingly, the flexible fixed styletable of demonstration bar direction
Provided with the second hook coordinated with the first hook.It is engaged using hook, the movement of flexible demonstration bar is easily facilitated, in order to teach
Duty personnel put out geometry more precisely.
Preferably, the gland is provided with caulking groove with flexible demonstration bar junction, accordingly, set inside the fixed cover
There is the convex portion being adapted with caulking groove.Convex portion is adapted with caulking groove so that flexible demonstration bar to be fixed with fixed sleeve part.
Preferably, the quantity of the fixed cover is three, three fixed covers are connected by stationary rope.
Preferably, the quantity of the apparatus for demonstrating is four, four apparatus for demonstrating are distributed in the corner of square floor.
The beneficial effects of the utility model are：
In the utility model, square plate bottom equivalent to polygon bottom surface, clergy can by moving back and forth apparatus for demonstrating,
And quantity of increase expansion link etc., demonstrate triangular pyramid, rectangular pyramid even polygonal pyramid to student so that classroom instruction more shape
As lively, student is easier to understand；Meanwhile flexible demonstration bar connects with fixed column upset, easily facilitates drilling for clergy
Show；And after flexible demonstration bar puts good position, mutually fixed by fixed sleeve part, student can be easy to pass round geometric figure, when
When not in use, fixed sleeve part can be dismantled, is easy to store.
