Abstract
The utility model discloses a novel multifunctional angular instrument which comprises an angle gage, a first ruler and a second ruler, wherein the first ruler, the second ruler and the angle gage are hinged with the center of the angle gage, and angle indexes are formed on the angle gage; and length scales are arranged on both the first ruler and the second ruler. The utility model has the benefits as follows: 1, the novel multifunctional angular instrument has a simple structure and is portable; 2, during angle measurement, the centre point of the angle gage reclines to the peak of an angle, the first ruler coincides with one edge of the angle, the numerical reading indicated on the angle gage of the second ruler is the degree of the angle, the first ruler and the second ruler can be used for measuring the edge length of the angle at the same time through one step, and the use is convenient; and 3, the novel multifunctional angular instrument is convenient for drawing triangles with set angles and edges.
Description
Technical field
The utility model relates to a kind of schooling apparatus, particularly a kind of multi-functional angular instrument.
Background technology
In the process of mathematical studying; usually can use protractor and ruler; but; existing protractor and ruler all are single products; protractor can only take measurement of an angle, and ruler then can only be measured length, should take measurement of an angle when taking measurement of an angle again when running into; can not disposablely finish, thus very inconvenient.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of simple in structure, easy to adjust, can take measurement of an angle simultaneously and the multi-functional angular instrument of length.
In order to solve the problems of the technologies described above, multi-functional angular instrument of the present utility model comprises protractor, also comprises first ruler and second ruler, and described first ruler, second ruler and protractor are articulated in the circle centre position of protractor, and described protractor is provided with angle index.
In order to measure length when taking measurement of an angle, multi-functional angular instrument of the present utility model is equipped with the length scale on described first ruler and second ruler.
The beneficial effect that the utility model is obtained is: (1) is simple in structure, is easy to carry; When (2) taking measurement of an angle, the centre point of protractor is abutted in the place, summit of angle, first ruler overlaps with a limit of angle, the reading that second ruler is indicated on protractor is the number of degrees of angle, simultaneously, first ruler and second ruler are measured two length of sides of angle in passing, and disposable can finishing is very convenient; (3) be convenient to draw the triangle of the specified angle and the length of side.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, protractor, 2, angle index, 3, the length scale, 4, first ruler, 5, second ruler.
The specific embodiment
As shown in Figure 1, multi-functional angular instrument of the present utility model comprises protractor 1, also comprises first ruler 4 and second ruler 5, and described first ruler 4, second ruler 5 and protractor 1 are articulated in the circle centre position of protractor 1, and described protractor 1 is provided with angle index 2; Be equipped with length scale 3 on described first ruler 4 and second ruler 5.
Multi-functional angular instrument of the present utility model, when taking measurement of an angle, the centre point of protractor 1 is abutted in the place, summit of angle, first ruler 4 overlaps with a limit of angle, the reading that second ruler is indicated on protractor 1 is the number of degrees of angle, and simultaneously, first ruler 4 and second ruler 5 are measured two length of sides of angle in passing, disposable can finishing, very convenient.
In addition, multi-functional angular instrument of the present utility model is convenient to draw the triangle of the specified angle and the length of side.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
