Abstract
The present invention provides a kind of multifunctional ruler, mainly include transverse axis and vertical pivot part, vertical pivot is perpendicular to transverse axis, parallel with vertical pivot and ganoid sliding bar passes and is fastened to from the inside of localizer the surface of vertical pivot, combination by cross bar Yu montant, add slide block to coordinate with slide bar, the ingenious of chute, achieve the integration to multiple independent drawing tools such as ruler, set square, compasses cleverly, solve the problem that current similar picture chi structure is complicated, flexibility ratio is poor and service efficiency is the highest, there is simple in construction, easy to operate feature.
Description
Technical field
The present invention relates to a kind of teaching aid, especially a kind of Multifunctional math teaching aid.
Background technology
The figure that free-hand drawing draws is the most lack of standardization but also unsightly, so for a teacher especially
For math teacher, will draw the geometric graph comparing specification, the drawing tool such as ruler, compasses is must
Indispensable.
What teachers used at present is all a set of traditional drawing tools, and this set instrument generally comprises directly
Chi, isosceles drawing square, the drawing square having foot to be 60 degree, compasses, protractor.
Each of this kit is all independent, often do a figure to use simultaneously the most several even
It is whole instruments, so teacher before class has to carry various teaching aid enters classroom, the most not
Convenient.For convenient fixing, the fixing foot bottom of general compasses is provided with pin, and this pin easily scratches
It is also possible to while blackboard user is damaged.
Summary of the invention
Above-mentioned disclosed front two drawing tools are directed to integrate existing independent drawing tools,
A kind of multifunctional ruler of design.
Integrate these independent drawing tools the most further, and new drawing tools can be made to have knot
Structure is simple, and it is flexible, convenient to use, it is possible to be effectively improved and the drawing efficiency that improves on blackboard
Advantage, the problem primarily thought deeply when becoming design drawing tools.
The present invention provides a kind of multifunctional ruler, solves that current similar picture chi structure is complicated, flexibility ratio is poor
And the problem that service efficiency is the highest.
The multifunctional ruler of the present invention mainly includes transverse axis and vertical pivot part, and vertical pivot is perpendicular to transverse axis；With
Parallel and the ganoid sliding bar of vertical pivot passes from the inside of localizer and is fastened to the table of vertical pivot
On face；Localizer can move up and down along sliding bar but can not rotate；The crown center side of localizer
Be provided with fixed screw, the centrage of fixed screw and the centrage of sliding bar orthogonal and with
In one plane；Chalk clamp is fixed on the side that localizer is close with sliding bar；At transverse axis two
The bottom of end and pin is provided with removable fixing glue；Cavity chute it is provided with inside transverse axis, sliding
Rooved face is smooth parallel with transverse axis；Inlay in the inside of chute and can move left and right in chute one by one
Dynamic sliding shoe；The lower end of vertical pivot is fixed on sliding shoe by pin, and whole vertical pivot part can slided
Move left and right along transverse axis under the regulation of motion block；Vertical pivot with transverse axis are both provided with length scale.
The described vertical pivot in multifunctional ruler is orthogonal with transverse axis, zero on length scale and vertical pivot
After graduation mark extends, by, in a kind of multifunctional ruler described in the center of circle of pin, length scale being marked on
On vertical pivot and transverse axis, the distance that localizer is moved can be recorded accurately, thus draw accurately
Go out the line segment of designated length in certain maximum and specify the circle of radius.
The described fixing glue in a kind of multifunctional ruler can be sucker can also be Magnet, utilize big
Air pressure and vacuum principle, as long as then the partial air extruded in sucker inner chamber is closely pressed in him light
Sliding and on the surface of face seal, CD just can be inhaled steady, and on the premise of without departing from smooth surface
Allow to hang up certain weight.Using Magnet is to make use of magnetic material there is a natural attraction between the sexes as fixing glue
Principle, current almost all of blackboard for education is both provided with Magnet, this is select magnet conduct
Fixing glue provides condition.
The multifunctional ruler combination by cross bar and montant, add slide block and slide bar, chute ingenious
Coordinate, achieve the integration to multiple independent drawing tools such as ruler, set square, compasses cleverly.
The rotary shaft drawing circle swing arm is arranged in the plane of multifunctional ruler, replaces consolidating of compasses by fixing glue
Determine stitch, solve needle of compasses and easily scratch blackboard, the problem easily user damaged.
Such design also solves the general compasses of use and paints bowlder on blackboard and gradually shorten along with chalk circle
The problem that can taper into of radius.Therefore the multifunctional ruler of the present invention has simple in construction, uses
Flexibly, conveniently, it is possible to the advantage of drawing efficiency being effectively improved and improving on blackboard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below according to accompanying drawing and combine detailed description of the invention the invention will be further described.
As it is shown in figure 1, multifunctional ruler of the present invention mainly includes transverse axis 2 and vertical pivot 9 two large divisions,
Vertical pivot 9 is perpendicular to transverse axis 2.Parallel with vertical pivot 9 and ganoid sliding bar 8 is from localizer 5
Inside passes and is fastened on the surface of vertical pivot 9.Localizer 5 can move down on sliding bar 8
Moving but can not rotate, the crown center place of localizer 5 is provided with fixed screw 4, fixed screw 4
The centrage of centrage and sliding bar 8 orthogonal and in approximately the same plane.Chalk clamp 10 quilt
It is fixed on the side that localizer 5 is close with sliding bar 8.In the two ends of transverse axis 2 and the bottom of pin 6
Being provided with removable fixing glue 1, transverse axis 2 is internal is provided with cavity chute 3, chute 3 smooth surface
Parallel with transverse axis 2, the cunning that can move left and right in chute one by one is inlayed in the inside of chute 3
Motion block 7.The lower end of vertical pivot 9 is fixed on sliding shoe 7 by pin 6, and whole vertical pivot 9 part can be
Move left and right along transverse axis 2 under the regulation of sliding shoe 7, be both provided with on transverse axis 2 at vertical pivot 9
Length scale 11.
Draw parallel lines: first take off the fixing glue 1 bottom pin 6, the fixing glue 1 at transverse axis 2 two ends
Set up and transverse axis is fixed on blackboard；Next is tightened 4 localizers 5 of fixed screw and is fixed on cunning
Certain position of bar 8, to the upper chalk of chalk clamp folder；Then allow whole vertical pivot 9 part at sliding shoe 7
Regulation under move from left to right along transverse axis 2, determined by the record distance that slips over of sliding shoe 7
The length of institute's line drawing section；Determine the distance of two parallel lines finally by adjustment localizer, then weigh
Multiple previous step, it is achieved the function drawn parallel lines.
Allow whole device be close to blackboard remote pin 6 rotate a circle, it is achieved draw the function of circle.
In sum, multifunctional ruler simple in construction of the present invention, use flexible, Ke Yi great
Amplitude improves the efficiency drawn on blackboard.
