Description
Technical field
Mathematical education technical field is the utility model is related to, specially a kind of mathematical education multifunctional teaching ruler.
Background technology
Mathematics can cultivate the logical thinking ability of people, be the basic quality that everyone should socially possess, and chi
A critically important ability in rule mapping and mathematics.
Primary school teaching chi function of the prior art is single, inconvenient to carry, and many figures are all by straight line and curve group
Conjunction forms, and the logical thinking ability of students in middle and primary schools is again poor, so needing the construction with ruler and compasses of specification, facilitates student in brains
Mathematical modeling is built, and teacher's mapping needs the mutual collocation of ruler, protractor and compasses to complete mostly, efficiency is low, and teaches
Chi is not wear-resisting, and long afterwards, the scale on chi will be unintelligible, influences to use, and is brought greatly to teaching job for usage time
Inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of mathematical education multifunctional teaching ruler, to solve above-mentioned background technology
The teaching ruler function of the prior art of middle proposition is single, uses complexity, it is impossible to fast and accurately draw the figure of specification, teacher
Ineffective problem.
To achieve the above object, the utility model provides following technical scheme：A kind of mathematical education multifunctional teaching ruler,
Including fixed knob, chalk hole, the first Expansion ruler, ruler, movable post, the second Expansion ruler, stopper slot, angle square, chalk
With protractor neck, first Expansion ruler and the second Expansion ruler are arranged on inside ruler in undercut, and the chalk can be inserted
Enter to install in chalk hole, the movable post is slidably mounted on stopper slot, and the angle square is pulled and pushed installed in protractor neck
In, the fixed knob is placed in movable post upper end position.
Preferably, the movable post is connected by movable seam with stopper slot.
Preferably, sky is provided with elastomeric material in the chalk hole, and the hole is up big and down small structure.
Preferably, it is provided with stopper slot on the ruler and the second Expansion ruler.
Preferably, the ruler and first Expansion ruler one end are provided with chalk hole.
Compared with prior art, the beneficial effects of the utility model are：The mathematical education with multifunctional teaching ruler is and directly
The device that chi, protractor and compasses are integrated, and there is Expansion ruler, avoid ruler in original construction with ruler and compasses from falling short of not
Foot, complicated accurate figure can be completed with the device, avoid inconvenience of the teacher because changing teaching ruler in original construction with ruler and compasses,
The efficiency of teachers ' teaching is improved, student is quickly built mathematical modeling in brain, and the material of the teaching ruler is wear-resisting
Material, the service life of teaching ruler is added, be the design of a more hommization.
Brief description of the drawings
Fig. 1 is the utility model ruler and protractor matching structure schematic diagram.
Fig. 2 is the utility model ruler and compasses matching structure schematic diagram.
Fig. 3 is the utility model section structural representation.
In figure：1st, fixed knob, 2, chalk hole, the 3, first Expansion ruler, 4, ruler, 5, movable post, 6, second is flexible straight
Chi, 7, stopper slot, 8, angle square, 9, chalk, 10, protractor neck.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of mathematical education multifunctional teaching ruler, bag
Include fixed knob 1, chalk hole 2, the first Expansion ruler 3, ruler 4, movable post 5, the second Expansion ruler 6, stopper slot 7, angle square
8th, chalk 9 and protractor neck 10, the first Expansion ruler 3 and the second Expansion ruler 6 are arranged in the inside undercut of ruler 4, are avoided
4 long frangibility of ruler, ruler 4 is too short, the embarrassment that setting-out falls short of, and chalk 9 can be inserted into installation chalk hole 2, movable post 5
It is slidably mounted on stopper slot 7, angle square 8 is pulled and pushed in protractor neck 10, and fixed knob 1 is placed in the movable upper end of post 5
Position, the lower end of fixed knob 1 can play fixation through movable post 5 and the hole in angle square 8 to protractor 8.
Further, movable post 5 is connected by movable seam with stopper slot 7, slidably can also be fixed, convenient mapping
When, flexibly use；
Further, sky is provided with elastomeric material in chalk hole 2, and the hole is up big and down small structure, can be fine
Limitation chalk, and can prevents fractureing for chalk；
Further, stopper slot 7 is provided with the Expansion ruler 6 of ruler 4 and second, contains buckle in stopper slot 7；
