Abstract
The utility model relates to a multifunctional gauge, which belongs to cultural and teaching goods and is characterized in that the multifunctional gauge is provided with a compass, the position of the top end of which is hinged with a protractor, the lower end of a fixed shaft foot of the compass is hinged with a transverse bar-shaped board which is crossed with the other shaft foot of the compass, one side edge of the bar-shaped board is a straight board edge, the other side of the bar-shaped board is a cambered edge, the side edge of the bar-shaped board is provided with scale lines, and the side edges of two shaft feet of the compass are also provided with the scale lines. The utility model has the advantages of simple structure and strong operability, integrates a ruler, a triangle, the compass and the protractor, and has the functions of measuring angles, drawing triangles and making circles and dividing rulers. The utility model is convenient for custody, carrying and the rapid completion of teaching tasks of teachers. The multifunctional gauge enhances the learning interest and the ability of using hands of students, and is helpful for cultivating the abilities of analyzing and solving problems of the students.
Description
Technical field
The utility model relates to a kind of schooling apparatus, particularly relates to a kind of multi-functional ruler-compasses of the usefulness of imparting knowledge to students, and is to the improvement of the ruler teaching aid structure of existing teaching usefulness, belongs to the school supply and stationery category, and suitable student and teacher use in teaching.
Background technology
At present, last class hour of teacher used teaching aids such as general ruler, function singleness can only be used separately, a class will be used a plurality ofly sometimes, carries inconvenience and easily loses, and is unfavorable for that the teacher makes full use of time in classroom and finishes teaching task quickly and easily.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of multi-functional ruler-compasses, this multi-functional ruler-compasses integrates ruler, set square, compasses, protractor, function with angulation, picture triangle, work circle and rule, be convenient to take care of and carry, help student and teacher to finish teaching task quickly.
The technical scheme that the utility model provides is: this multi-functional ruler-compasses, be characterized in that compasses are arranged in the described ruler, be hinged with a protractor at the compasses top end, be hinged with a horizontal stripe board in the lower end of compasses fixed axis pin, this another pin of horizontal stripe board and compasses intersects, and a side of stripe board is straight edges of boards, and another side of stripe board is the arc limit, the side of stripe board is provided with graduation mark, also is provided with graduation mark on the side of two axle pin of compasses.
Compared with prior art, the utlity model has simple in structure, easy to carry, function is more and use flexible characteristic, has thoroughly solved teacher changes teaching aid continually in teaching inconvenience.
Description of drawings
Accompanying drawing is the structural representation of the embodiment that provides of the utility model.
Number in the figure: 1. protractor, 2. compasses, 3. stripe board.
The specific embodiment
As shown in the figure, compasses 2 are arranged in this multi-functional ruler-compasses that the utility model provides, be hinged with a protractor 1 at compasses 2 top ends, be hinged with a horizontal stripe board 3 in the lower end of compasses 2 fixed axis pin, this horizontal stripe board 3 is intersected with compasses 2 another pin, and a side of stripe board 3 is straight edges of boards, and another side of stripe board 3 is the arc limit, the side of stripe board 3 is provided with graduation mark, also is provided with graduation mark on the side of two axle pin of compasses 2.
During use, after ruler closed up, utilize the graduation mark on 2 two axle pin of compasses side, can reach the effect of ruler; After ruler suitably opened, utilize the hinged stripe board 3 in lower end of compasses 2 fixed axis pin, make horizontal the intersecting of stripe board 3 straight edges of boards, can reach the effect of set square with compasses 2 another pin; Is a left-right rotation with protractor 1 with compasses 2 top ends, can bring into play the effect of protractor; After ruler opened, can be the center of circle at compasses 2 fixed axis pin, compasses 2 another pin be radius with the value of stripe board 3 arc limit high scale lines, and the circle of size arbitrarily can draw.
