Description
Technical field
This utility model is related to a kind of drawing tools, specifically a kind of mathematical education drawing tools.
Background technology
Mathematics is a subject of the concepts such as research quantity, structure, change, space and information, genus in terms of certain angle
In one kind of formal science, borrow《Mathematics brief history》If, mathematics is exactly to study collection to close the science of various structures (relation), can
See, mathematics is an abstract subject, and rigorous process is the key of mathematical abstractions, and mathematics is in development of human history and society
Play irreplaceable effect in life, be also study and the research requisite basic tool of modern science and technology, at present,
In mathematics several teaching, often need to first chart and then solve conclusion, conventional instrument of drawing have ruler, radian chi, protractor,
Compasses etc., need to carry more drawing tool during teachers simultaneously, often alternately change and use, and drawing tools is many due to sample number,
Not portable, in-convenience in use, and can not directly draw required pattern, bring many inconvenience to teaching.
Utility model content
The purpose of this utility model is to provide a kind of mathematical education drawing tools, to solve to carry in above-mentioned background technology
The problem going out.
For achieving the above object, this utility model provides following technical scheme：
A kind of mathematical education drawing tools, including main ruler, cylinder, secondary ruler and curved angle chi, described main ruler
Upper right is fixed with the cylinder with main parallel, is provided with bar shaped fluting on the right side of cylinder, and inner barrel has cylinder
Cavity, is provided with spring connecting shaft in cavity, spring connecting shaft is uniformly provided with some involute shape springs, on involute shape spring
It is arranged with winch spool, winch spool is wound with transparent PVC roll material, PVC roll material end is provided with block, and PVC roll material is provided with three
Angular hollow out, polygon hollow out, the circular hollow out of some different-diameters, oval hollow out and protractor hollow out；Described main ruler
By having secondary ruler by stud connection, main ruler left side central portion is fixed with curved angle chi, main ruler and arc angle for bottom
Degree chi is integrally formed, and curved angle chi is provided with arc chute, and secondary ruler is provided with the lead being adapted to arc chute.
Further, the described axis of spring connecting shaft is overlapped with the axis of cavity.
Further, the width of described block is more than the width of bar shaped fluting.
Further, described main ruler and secondary ruler edge are respectively equipped with graduation mark.
Further, described main ruler top is provided with non-slipping block.
Further, described pair ruler top is provided with chalk draw-in groove.
Compared with prior art, this utility model, when drawing some figure sketches, extracts PVC roll material out, by PVC roll material
Various hollow outs can conveniently draw the sketch of demand, when not using, involute shape spring will wind PVC roll material volume automatically
Move into cavity inside, convenient and swift, teacher is contributed to by cylinder and grips this utility model drawing tools；Main ruler and secondary ruler
As two supporting legs of compasses, in chalk draw-in groove, put into chalk, main ruler is rotated to required radius by hinge with secondary ruler
Size, non-slipping block one end and blackboard contact point are the center of circle, can draw the circle required for teaching by rotation force.
Brief description
Fig. 1 is the structural representation of mathematical education drawing tools.
Fig. 2 is the structural representation of mathematical education drawing tools middle cylinder body.
Specific embodiment
With reference to specific embodiment, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-2, a kind of mathematical education drawing tools, including main ruler 1, cylinder 2, secondary ruler 4 and arc angle
Degree chi 5, described main ruler 1 upper right is fixed with the cylinder 2 parallel with main ruler 1, is provided with bar shaped fluting on the right side of cylinder 2
21, there is inside cylinder 2 cavity of cylinder, in cavity, be provided with spring connecting shaft 22, the axis of spring connecting shaft 22 and cavity
Axis overlap, spring connecting shaft 22 is uniformly provided with some involute shape springs 23, involute shape spring 23 is arranged with
Winch spool 3, winch spool 3 is wound with transparent PVC roll material 31, and PVC roll material 31 end is provided with block 32, and the width of block 32 is big
In the width of bar shaped fluting 21, PVC roll material 31 is provided with triangle hollow out 33, polygon hollow out 34, the circle of some different-diameters
Shape hollow out 35, oval hollow out 36 and protractor hollow out 37, when drawing some figure sketches, extract PVC roll material 31 out, by PVC roll
Various hollow outs on material 31 can conveniently draw the sketch of demand, and when not using, involute shape spring 23 will wind automatically
PVC roll material 31 winds into cavity inside, convenient and swift, contributes to teacher by cylinder 2 and grips this utility model drawing tools；Institute
State main ruler 1 bottom by secondary ruler 4 is had by stud connection, main ruler 1 left side central portion is fixed with curved angle chi 5, main
Ruler 1 and curved angle chi 5 are integrally formed, and curved angle chi 5 is provided with arc chute 51, and secondary ruler 4 is provided with to be slided with arc
