Abstract
The utility model provides a special teaching aid for mathematics teachers, which belongs to teaching aids, and structurally comprises a triangular ruler formed by splicing a straight ruler and two slide rulers. A graphometer is arranged on the inner side of the straight ruler; a curved line is arranged on the inner side of each slide ruler; a slide way is arranged on each slide ruler; the top portions of the two slide rulers are crossed and slidably connected through a slide post; the slide post is arranged inside the slide way; two ends of the slide post are respectively fixed by a fixing fastener and a magnetic adhering sheet; and the tail ends of the slide rulers are movably connected with the straight ruler through a shaft pin. Compared with the prior art, the special teaching aid for the mathematics teachers has the advantages of reasonable design, simple structure, complete functions, convenient use and the like, brings convenience for the teachers to draw pictures, and is wide in application.
Description
Technical field
The utility model relates to a kind of educational aid, a kind of specifically multifunction teaching teaching aid of mathematics teacher's special use.
Background technology
Math teacher is given lessons and often will be used ruler on mathematics class, set square, educational aids such as graphometer, and prior art set square substantially all be drawing square or the isoceles triangle chi of fixing, its leg-of-mutton length of side and interior angle all can not regulated at will, limited the use of set square, simultaneously the scale of ruler uses of a specified duration will to wear and tear and fades, thereby lose measurement function, when giving lessons, the mathematics teacher need multiple ruler to be used, palm is wayward, slide easily, not ideal, the special-purpose teaching aid of some mathematics teachers that piece together has appearred now, though function is complete slightly, and complex structure, use inconvenience, the teachers ' teaching process is brought inconvenience, promptly lose time and expend teacher's energy.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, multiple functional mathematics teacher is provided special-purpose teaching aid.
The technical solution of the utility model realizes in the following manner, the special-purpose teaching aid of this mathematics teacher, its structure comprises set square, set square is spliced by ruler and two slide rules, described ruler inboard is provided with graphometer, the slide rule inboard is provided with curve, slide rule is provided with slideway, article two, the slide rule top intersects and is slidingly connected by traveller, described traveller is arranged in the slideway, the traveller two ends are fixed by clip and Magnetic adhesive mat respectively, and the end of slide rule then flexibly connects by pivot pin and ruler.
Described slide rule, ruler arranged outside have scale, cover one deck plastic foil on the scale.
Traveller between the described slide rule is provided with rubber ring.
The beneficial effect that the utility model is compared with prior art produced is:
The special-purpose teaching aid of mathematics teacher of the present utility model has characteristics such as simple in structure, multiple functional, easy to use, integrate multiple educational aid, can be used as curve ruler, ruler, graphometer and set square uses, and two edge lengths of set square are adjustable, it is convenient to map when making teachers' instruction, and the content that can intuitively the teacher will be taught is shown to the student, and it is concrete changing abstract, reduce teacher's workload simultaneously, time saving and energy saving; Be widely used, can be applicable to ground such as school, training organization.
