Description
One, technical field:
The utility model relates to the mathematic(al) construction instrument that uses in mathematical education, mathematical studying and the Mathematics Application, what be specifically related to is a kind of multifunctional mathmatical drawing tool.
Two, background technology:
Often will use various mathematic(al) construction instruments in mathematical education, mathematical studying and the Mathematics Application, like compasses, rule, set square, protractor, slide calliper rule etc., existing several kinds of common mathematical drawing tools nearly all are independent individualities; Also have protractor and set square combined; But these mathematic(al) construction instruments are function singleness still, basically all is to solve more single mapping problem, and people are when mathematic(al) construction; Just to not accomplish one or both mappings; But to accomplish multiple mapping, so people's office bag (school bag) lining often is equipped with compasses, rule, set square, protractor, slide calliper rule etc. simultaneously, owing to compasses, rule, set square, protractor, slide calliper rule etc. all are independent individualities; Make in people's the bag more in disorder, bad management.
Three, summary of the invention:
The purpose of the utility model provides a kind of multifunctional mathmatical drawing tool, and it is used to solve present several kinds of common mathematical drawing tools all is that independent individuality causes carrying and managing inconvenient problem.
The technical scheme that the utility model adopted is: the main body of this multifunctional mathmatical drawing tool is the open straight tri-prismoid of an end; The sealing bottom surface of straight tri-prismoid is a right angled triangle; The open end of straight tri-prismoid is provided with isosceles right angle triangle and protractor; The isosceles right angle triangle is connected through little axle with a side of main body, and protractor is connected through little axle with second side of main body; The 3rd side of main body is provided with compasses, and compasses are made up of bar-shaped trough, mobile supporting leg, fixed supporting leg, and fixed supporting leg is fixed on this side; The end of fixed supporting leg is the compasses points; Mobile supporting leg is gone up the installation supporting leg by mobile seat and is constituted, and the end of supporting leg is a stationary magazine creel, and pencil is inserted in the stationary magazine creel; Mobile seat is installed in the bar-shaped trough, is slidingly connected with bar-shaped trough.
Upper edge, the side rib of the straight tri-prismoid in the such scheme is provided with graduation mark, as rule.
Compasses have buckled the strip box outward in the such scheme, and box and main body are splits, and box had both been protected compasses in can compasses being contained in when being buckled in outside the compasses, make the convenient placement of the utility model again, after box is taken off, can draw circle with compasses.
One of two acute angle of the right angled triangle of sealing bottom surface are 30 degree in the such scheme, and another is 60 degree.
Beneficial effect:
1, the utility model is designed to one dexterously with compasses, rule, set square, protractor, and various functional specifications are handy, and is convenient to management, easy to carry.
2, the utility model also can be put into drawing tool inside with pen, paper, brings great convenience for teacher, student and engineers and technicians, makes their working and learning handy.
3, the utility model is simple in structure, and applicability is strong.
Four, description of drawings:
Fig. 1 is the structural representation of the utility model.
1 isosceles right angle triangle, 2 protractors, 3 bar-shaped troughs 4 move supporting leg 5 fixed supporting legs 6 and move seat 7 graduation marks.
Five, the specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1, the main body of this multifunctional mathmatical drawing tool is the open straight tri-prismoid of an end, and the sealing bottom surface of straight tri-prismoid is a right angled triangle, and one of two acute angle of this right angled triangle are 30 degree, and another is 60 degree.The open end of straight tri-prismoid is provided with isosceles right angle triangle 1 and protractor 2, and isosceles right angle triangle 1 is connected through little axle with a side of main body, and isosceles right angle triangle 1 can rotate around little axle; When using; Isosceles right angle triangle 1 is flipped out,, isosceles right angle triangle 1 is turned back in the tri-prismoid when time spent not; Protractor 2 is connected through little axle with second side of main body, and the method for using of protractor 2 is identical with isosceles right angle triangle 1; The 3rd side of main body is provided with compasses.The closed side at each rib place of straight tri-prismoid all has graduation mark 7, and graduation mark 7 is along the rib setting, and each rib of straight tri-prismoid can be used as rule and uses.
Compasses are made up of bar-shaped trough 3, mobile supporting leg 4, fixed supporting leg 5; Fixed supporting leg 5 is fixed on above-mentioned the 3rd side of main body, and the end of fixed supporting leg 5 is compasses points, and the installation supporting leg constitutes on the seat 6 by moving to move supporting leg 4; Moving seat 6 is installed in the bar-shaped trough 3; Be slidingly connected with bar-shaped trough 3, the end of supporting leg is a stationary magazine creel, and pencil is inserted in the stationary magazine creel.During use, the big young pathbreaker of the circle of drawing as required moves supporting leg 4 and slides into corresponding position, specifically can select size with reference to the graduation mark on this side 7, fixed supporting leg 5 is scheduled some rotating main body, the circle that just can draw and need.
The utility model is convenient to be placed in order to make, and compasses have buckled the strip box outward, and box and main body are splits, can protect compasses when box is buckled in outside the compasses, draw bowlder with compasses, and box is taken off.
Because the utility model is the open straight tri-prismoid of an end, so main body can also be used as parcel tray, can pen, paper be put into drawing tool inside.
The main body of the utility model can adopt transparent hard plastic to process.
The utility model is designed to one dexterously with compasses, rule, set square, protractor, and function is many, easy to use and management, easy to carry.
