Description
Technical field
The utility model is related to mathematical education technical field, more particularly to a kind of mathematical education drawing device.
Background technology
Mathematics is segmented into two major classes, and a class is pure mathematics, and a class is applied mathematics.Pure mathematics is also basic number
Learn, specialize in the inherent laws of mathematics in itself.The algebraically introduced in middle and primary schools' textbook, geometry, calculus, probability theory knowledge,
Belong to pure mathematics.One distinguishing feature of pure mathematics, is exactly temporarily to bypass particular content, and things is studied with pure form
Quantitative relation and space form.Applied mathematics is then conceived to explanation natural phenomena, and solving practical problems are pure mathematics and section
Bridge between technology.
At present, in the plane geometric figure teaching process of mathematics, straight line and the polygonal content of courses can be related to, it is existing
Have in teaching method, the mode for often relying on blackboard drawing is explained, but when being drawn in teaching process, existing picture
Instrument can not be quickly the angle straight line for drawing different types of triangle and different angle, cause troublesome poeration, efficiency is low
Under, especially when carrying out more triangle or the drafting of angle straight line, speed is slower, is unfavorable for the progress of teaching.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art there is provided a kind of mathematical education drawing device,
It is simple in construction, easy to operate, picture efficiency high.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of mathematical education drawing device, including annular bottom plate, magnet slide block and elastic threads, the annular bottom plate
The circle of inner side one, which is provided with annular groove, annular groove, is provided with three magnet slide blocks, and annular groove is iron chute, and magnet is slided
Block includes column and is arranged on the magnet of column top and bottom, and magnet slide block is by being arranged on the magnetic of column top and bottom
Iron is embedded in annular groove in magnetic absorption mode, and the hypomere part of column sets the link that oriented annular groove is overhang,
The elastic threads for snap the line are fixed with by link between three magnet slide blocks.
Further, it is coated with chalk powder in above-mentioned elastic threads.
Further, above-mentioned elastic threads are made up of elastomeric material.
Further, above-mentioned elastic threads are stretchy nylon rope or hollow tubular rubber.
Further, above-mentioned magnet slide block is cylindric.
Relative to prior art, the utility model has the advantages that：
The utility model provides a kind of mathematical education drawing device, and simple in construction, easy to operate, picture efficiency high makes
Used time can quickly can be obtained by changing position of the magnet slide block in annular groove and being equipped with the uses of elastic threads by snap the line
To different triangles and the angle straight line of different angles, efficiency is significantly improved, beneficial to the progress of teaching.

Embodiment
Below in conjunction with the accompanying drawings, an 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 embodiment.
A kind of mathematical education drawing device structural representation that Fig. 1 provides for the utility model embodiment.As shown in figure 1,
The mathematical education drawing device is specifically included：Including annular bottom plate 101, magnet slide block 102 and elastic threads 103.
As shown in figure 1, the circle of inner side one of annular bottom plate 101 is provided with annular groove 104, annular groove 104 and set
Have three magnet slide blocks 102, annular groove 104 is iron chute, as shown in Fig. 2 magnet slide block 102 include column 102-1 with
And the magnet 102-2 of column 102-1 top and bottom is arranged on, magnet slide block 102 is by being arranged on column 102-1 upper ends with
The magnet 102-2 at end is embedded in annular groove 104 in magnetic absorption mode, and column 102-1 hypomere part sets directed loop
The bullet for snap the line is fixed between the link 102-3 that shape chute 104 is overhang, three magnet slide blocks 102 by link 102-3
Property rope 103.Further, in order to be coated with chalk powder in snap the line, elastic threads 103 on blackboard by elastic threads 103, in this reality
With in new embodiment, elastic threads 103 are made up of elastomeric material, with certain elasticity, and can be stretched, in mobile magnetic
When iron slider 102, the angle between the tensile elongation and elastic threads of elastic threads 103 can be changed, so that three elasticity
Rope 103, which turns into one, has the triangle that three lines have been, by these three elastic threads, can distinguish snap the line, one is obtained on blackboard
Individual triangle, also can carry out snap the line by two elastic threads therein, obtain the angle straight line with certain angle, specifically
