Abstract
The utility model belongs to a novel geometrical drawing diagraph which integrates the functions of a traditional semicircle instrument, a compass, a flat ruler, and a set square, which is used in the classroom teaching for teachers. The utility model is made of transparent plastic with high hardness, which is composed of a semicircle instrument (1) and a flat ruler (2), wherein the two parts are connected through a connecting button (3) on the circle center of the semicircle instrument (1), and scale marks are marked on the bottom edge of the semicircle instrument (1). The flat ruler (2) whose one end is close to the semicircle instrument (1) is designed to a pointed shape, which is used for angle indicating, and a row of nib jacks (4) is designed on the other end of the flat ruler (2), and a circle can be drawn through rotating the flat ruler (2).
Description
Technical field:
The utility model belong to a kind of merged traditional compasses, ruler, set square, graphometer function for teachers ' classroom teaching the time the novel drawing tool that uses.
Background technology:
The teacher often uses that educational aids such as compasses, ruler, set square, graphometer take measurement of an angle, length, mapping in daily teaching work, how convenient, accurately directly have influence on the efficient of teaching.The present above-mentioned instrument that uses, function singleness is carried inconvenience, loses damage easily, and the production cost height can not satisfy teacher's classroom instruction need of work.
Be badly in need of in the teaching a kind of can merge take measurement of an angle, the drawing instrument of length, the multiple function of picture circle, increase work efficiency.
Summary of the invention:
Main task of the present utility model is to provide a kind of novel mapping educational aid simple in structure, multiple functional, easy to use, economic cheap for the teaching of teacher's problem.
The utility model is achieved in that it makes with the high-hard, transparent plastics, is made of graphometer and ruler two parts, and the connection button by the graphometer circle centre position links together the two.The base of graphometer indicates scale, can measure length.The nearly graphometer end of ruler is designed to pointed, is used to refer to angle, and other end design has spread pen point jack, rotates ruler and can be used to the picture circle.
Advantage of the present utility model is: length, angle function are justified, measured to the picture that merges traditional compasses, ruler, set square, graphometer in one, and be simple in structure, multiple functional, easy to use, helps increasing work efficiency; The huge market demand, production cost is low, is convenient to marketing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, the 1st, graphometer, the 2nd, ruler, the 3rd, connection button, the 4th, nib jack.
The specific embodiment:
In conjunction with the accompanying drawings embodiment of the present utility model is described further: the base of graphometer (1) and ruler (2) can be used to measure length, and both cooperations can be played the effect of set square, can come picture 0-180 ° angle.When taking measurement of an angle, one side of institute's angle measurement is overlapped with the base of graphometer (1), the summit at angle is that connection button (3) is located to overlap with the center of circle of graphometer (1), rotates ruler (2) and overlaps with the another side of institute angle measurement, can read angle numerical value from graphometer (1).Drawing bowlder, is that connection button (3) be the center of circle with the center of circle of graphometer (1), and pen is put into the nib jack (4) that is positioned at ruler (2) one ends, can the draw circle of different radii of rotation ruler (2).
Claims (2)
1. novel geometric figure diagraph is characterized in that: be made of graphometer (1) and ruler (2) two parts, the connection button (3) by graphometer (1) circle centre position links together graphometer (1) and ruler (2).
2. according to the described novel geometric figure diagraph of claim 1, it is characterized in that: the base of graphometer (1) indicates scale, and nearly graphometer (1) end of ruler (2) is designed to pointed, is used to refer to angle, other end design has spread pen point jack (4), rotates ruler (2) and can be used to the picture circle.
