Description
Technical field
This utility model relates to mathematical education clothing arts, is specially a kind of mathematical education apparatus for demonstrating.
Background technology
The geometric figure such as circle, ellipse, parabola is the basic X-Y scheme in mathematical studying, but in teaching
During teacher want one time one time on blackboard, draw two-dimensional coordinate system, and draw out such figure, oval and
Parabola is not as circle when drawing can be by instrument, and it can only go to draw by the experience of teacher, because of
This more bothers and wastes time, and the bad student learning that can affect sometimes drawn, therefore it is badly in need of one
Plant the instrument of the figures such as convenient demonstration ellipse and parabola.The patent of Application No. 201420405230.1 is open
A kind of mathematical education demonstration board, its technical scheme includes that square plate body, described plate body front are provided with two dimension seat
Mark system, the described lower section of coordinate system transverse axis, the left side of the longitudinal axis are equipped with coordinate writing frame, described plate body set
The aperture of queueing discipline, described mathematical education demonstration board is had also to include elastic strip, be provided with T-shaped in described elastic strip
Groove, be provided with the slide block matched with T-slot in described T-slot, described slide block is provided with and coordinates with aperture
Plug,
The queueing discipline of described aperture is corresponding with coordinate system, and described plate body is arranged over stay cord, states the plate body back side four
It is provided with sucker at individual angle.Although this technical scheme can help teacher to demonstrate the curve such as ellipse, parabola, but
What the plug coordinating aperture can not link up moves, and does not has grid lines on panel, is not easy to teacher quick and precisely
The various curve of demonstration.Therefore devise a kind of mathematical education apparatus for demonstrating, institute can be determined fast and accurately
The key coordinate point of demonstration curve, also can link up as required and move the point of constituent curve easily.
Utility model content
The purpose of this utility model is to provide a kind of mathematical education apparatus for demonstrating, can determine fast and accurately
The key coordinate point of demonstrated curve, also can link up as required and move the point of constituent curve easily.
To achieve these goals, this utility model is achieved by the following technical solutions:
A kind of mathematical education apparatus for demonstrating, including plate body 2, it is characterised in that: the upper surface of described plate body 2 sets
Have iron sheet, plate body 2 be provided around frame 1, frame 1 is provided with coordinate number 102, if described plate body 2 is provided with
Dry chute 203, is provided with some slide blocks 3 in chute 203, slide block 3 connects magnet piece 4, described chute 203
Parallel with X-axis and spaced equal, described plate body 2 is provided with and chute 203 is perpendicular and is spaced equal erecting
Straight line 201, its point of intersection is provided with circular hole 202.
Described magnet piece 4 is provided with handle installing hole 401, is provided with handle 5 in handle installing hole 401.
Described plate body 2 is rubber slab.
Described frame 1 be arranged over handle 101.
The beneficial effects of the utility model are: can be fast and accurately with the grid that vertical curve is constituted by chute
Determine key coordinate point, magnet piece can be moved to determining position by coordinating of chute and slide block, and Magnet can
It is fixed on plate body by suction, thus the coherent point moving constituent curve easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Shown in figure: frame 1, plate body 2, slide block 3, magnet piece 4, handle 5, handle 101, coordinate number
102, vertical curve 201, circular hole 202, chute 203, handle installing hole 401.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to accompanying drawing 4, structure of the present utility model and beneficial effect thereof are further illustrated.
Example 1:
A kind of mathematical education apparatus for demonstrating, shown in Fig. 1 to Fig. 4, including plate body 2, the upper surface of described plate body 2

Some chutes 203, are provided with some slide blocks 3 in chute 203, slide block 3 connects magnet piece 4, described chute 203
Parallel with X-axis and spaced equal, described plate body 2 is provided with and chute 203 is perpendicular and is spaced equal erecting
Straight line 201, its point of intersection is provided with circular hole 202.
Described magnet piece 4 is provided with handle installing hole 401, is provided with handle 5 in handle installing hole 401.
Described plate body 2 is rubber slab.
Described frame 1 be arranged over handle 101.
Work process of the present utility model: first hang on blackboard by handle 101, then according to done figure
Need, frame 1 marks coordinate, after determining the key coordinate point constituting figure, handle 5 can be inserted
In handle installing hole 401, magnet piece 4 is coordinated in the coordinate points moved by chute 3 and slide block 4,
It is sequentially completed the drafting of figure.
It is obvious to a person skilled in the art that this utility model is not limited to the thin of above-mentioned one exemplary embodiment
Joint, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to concrete with other
