Description
Technical field
This utility model is related to teaching demonstration device technical field, and in particular to a kind of background mathematics demonstrator.
Background technology
Background mathematics is a subject of the inherent laws for specializing in mathematics itself, the generation that introduces in middle and primary schools' textbook
Several, several how knowledge belong to background mathematics.When carrying out background mathematics knowledge and lecturing, especially geometric correlation knowledge
In cognitive process, be difficult to understand for by language and word merely, need teacher that free-hand drawing is carried out on blackboard.This method was both
Waste time and energy, but inaccurate, it is easy to draw wrong.Prior art is badly in need of one kind can be to geometry in background mathematics and its relevant knowledge
Enter the background mathematics demonstrator of accommodating demonstration.This utility model is provided a kind of can conveniently demonstrate symmetric figure, figure
The background mathematics demonstrator of the aspect knowledge such as translation and the rotation of figure.
Utility model content
This utility model provides a kind of background mathematics demonstrator, can solve the problems referred to above of the prior art.
This utility model provides a kind of background mathematics demonstrator, including：Base plate, multiple column buttons, multiple extensible members
And power supply, the base plate is provided with grid, intersection of the plurality of column button installed in the grid, the plurality of post
Annular groove and display lamp is equipped with the top of shape button, and the two ends of the extensible member are equipped with little ring, and the extensible member passes through
The little ring is hung on column button described in any two, and the display lamp is by the column button and power electric connection.
It is preferred that the extensible member is elastic threads or expansion link.
It is preferred that being additionally provided with sprung parts at the top of the base plate.
It is preferred that the bottom of the base plate is additionally provided with the placement plate of horizontal direction.
Compared with prior art, the beneficial effects of the utility model are：Demonstrator of the present utility model can be with convenient and swift
Many-sided knowledge such as ground demonstration symmetric figure, the translation of figure and the rotation of figure, have very strong captivation to student, swash
Student learning interest is sent out, teaching efficiency is improved.
Description of the drawings
A kind of structural representation of background mathematics demonstrator that Fig. 1 is provided for this utility model.
Description of reference numerals：
1- base plates, 2- grids, 3- column buttons, 4- extensible members, 5- sprung partses, 6- place plate.
Specific embodiment
Below in conjunction with the accompanying drawings 1, a specific embodiment of the present utility model is described in detail, it is to be understood that this
The protection domain of utility model is not limited by specific embodiment.Embodiment in based on this utility model, this area are general
The every other embodiment obtained on the premise of creative work is not made by logical technical staff, belongs to this utility model
The scope of protection.
A kind of background mathematics demonstrator that this utility model is provided, including：Base plate 1, multiple column buttons 3, multiple flexible
Part 4 and power supply, the base plate 1 are provided with grid 2, intersection of the plurality of column button 3 installed in the grid 2, institute
The top for stating multiple column buttons 3 is equipped with annular groove and display lamp, and the two ends of the extensible member 4 are equipped with little ring, described
Extensible member 4 is hung on column button 3 described in any two by the little ring, and the display lamp is by 3 He of column button
Power electric connection.
Using background mathematics demonstrator of the present utility model, shape of the teacher according to figure to be demonstrated, press corresponding
Column button 3, then elastic component 4 is hung on corresponding column button 3 according to the shape of figure, that is, forms figure.This
Process operation is simple, and the design of column button 3, display lamp and extensible member 4 is motivated students' interest in learning significantly, strengthens student
Manipulative ability, so as to improve learning interest.
Further, the display lamp press for column button 3 go out, i.e. bright display lamp of upspringing.So design can be with
The figure of structure is more projected, make operating process more attractive.
Further, the extensible member 4 is elastic threads or expansion link, convenient and swift using elastic threads, using expansion link energy
The more vivid protrusion of figure is enough made, strengthens visual effect.
Further, the top of the base plate 1 is additionally provided with sprung parts 5, this demonstrator can be hung when using
Come, facilitate everybody to watch.
Further, the bottom of the base plate 1 is additionally provided with the placement plate 6 of horizontal direction, for placing extensible member 4, makes religion
Learn environment cleaner and tidier, and can prevent extensible member 4 from losing.
Demonstrator of the present utility model can conveniently and efficiently demonstrate symmetric figure, the translation of figure and the rotation of figure
Deng the Multifunctional demonstration of many-sided knowledge, with very strong captivation, motivate students' interest in learning, improve starting for student
Ability, improves teaching efficiency.
