Abstract
The utility model relates to a multifunctional ruler which is formed by foldable connection of a base ruler, a left auxiliary ruler and a right auxiliary ruler respectively through two hinges. Both auxiliary rulers are respectively provided with two small holes; the ratio of the straight line distances between both small holes in the right auxiliary ruler to the right hinge is 1:2 (square root), and the ratio of the straight-line distances between both small holes on the left auxiliary ruler to the left hinge is 3 (square root):2 (square root); the multifunctional further comprises a fixing pin capable of being inserted into both small holes which are overlapped under the folding state, and the fixing pin and the small holes are in interference fit; and each hole is sequentially provided with a corresponding angle marker, the angles corresponding to the both small holes in the right auxiliary ruler are respectively 60 degrees and 45 degrees, and the angles corresponding to both small holes in the left auxiliary ruler are respectively 30 degrees and 45 degrees. With the multifunctional ruler, the isosceles triangular angles, the right-angle triangular angles and some triangular angles with special angles can be conveniently drawn only by using one ruler as the ruler has corresponding angle mark; and the multifunctional ruler has the characteristics of simple structure and convenient use and carrying.
Description
Technical field
The utility model relates to a kind of drawing stationery, relates to a kind of multifunctional ruler specifically.
Background technology
The present most function singleness of chi of general common usefulness, one has only a kind of function to chi, for the student and the clerical workforce that will satisfy the multiple technique of painting and amount method needs, don't fail to be inconvenient to use and carry with the chi of various difference in functionalitys.
Summary of the invention
The utility model is intended to overcome the defective of prior art, and a kind of multifunctional ruler is provided, have simple in structure, the characteristics of conveniently using and carrying.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of multifunctional ruler, it be by a basic chi and about auxilliary chi, be formed by connecting collapsibly by two hinges respectively.
Be respectively equipped with two apertures on described two auxilliary chis, two apertures on inside right forward's chi with the ratio of the air line distance of right hinge are
Two apertures on inside left's chi with the ratio of the air line distance of left hinge are
Also comprise a steady pin that can insert two apertures that overlap under the folded state, this steady pin and aperture are interference fit.
Described each place, hole is provided with corresponding angle mark successively, and the angle of two aperture correspondences on inside right forward's chi is respectively 60 ° and 45 °, and the angle of two aperture correspondences on inside left's chi is respectively 30 ° and 45 °.
Use the utility model, can be easily only with one the chi triangle at isosceles triangle, right angled triangle and some special angles that draws, have simple in structure, the characteristics of conveniently using and carrying.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is a structural representation of the present utility model.
Fig. 2,3 is a user mode schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1: a kind of multifunctional ruler, it be by a basic chi 1 and about auxilliary chi 2,3, be formed by connecting by two hinges 4,5 respectively.
Be respectively equipped with two aperture a, b, c, d on described two auxilliary chis, two aperture c, d on inside right forward's chi with the ratio of the air line distance of right hinge 5 are
Two aperture a, b on inside left's chi with the ratio of the air line distance of left hinge 4 are
Also comprise a steady pin that can insert two apertures that overlap under the folded state, this steady pin and aperture are interference fit.
Described each place, hole is provided with corresponding angle mark successively, and two aperture c on inside right forward's chi, the angle of d correspondence are respectively 60 ° and 45 °, and two aperture a on inside left's chi, the angle of b correspondence are respectively 30 ° and 45 °.
Use the utility model, can be easily only with one the chi triangle at isosceles triangle, right angled triangle and some special angles that draws, have simple in structure, the characteristics of conveniently using and carrying.
As shown in Figure 2: folding described multifunctional ruler, hole b, d are overlapped, at this moment, described multifunctional ruler is an isosceles right triangle.
As shown in Figure 3: folding described multifunctional ruler, hole a, c are overlapped, at this moment, described multifunctional ruler is the right angle special triangle.
This utility model has simple in structure, the characteristics of conveniently using and carrying.
