Abstract

The invention discloses a multifunctional mapping ruler which comprises a disc with 360 DEG angle scale and a ruler with length scales; a hole is opened in the center of the disc; a hole is also arranged on the end with smaller ruler scales; the disc and the ruler cross the two holes through a shaft; the ruler and the disc can rotate around the shaft; a long and thin slot is arranged on the medial axis paralleled with the lateral side of the ruler. The multifunctional mapping ruler designed and made by the invention has the advantages of simple structure, convenient use, integrated functions of ruler, compass and angle gauge, simplified mapping work and flexible use.

Description

A kind of multifunctional drawing ruler
Technical field
The present invention relates to a kind of drawing ruler, is a kind of multifunctional drawing ruler that can be fit to the mapping of multiple figure specifically.
Background technology
In mapping, we can have some difficulties unavoidably, such as, when making equilateral triangle, relating to angle and length, at this time traditional way is to cooperate with ruler and protractor to finish, and justifies if add, and just must be with compasses.Troubles that the instrument that so carries is many, the two is easily lost.
Therefore, designing a kind of multifunctional drawing ruler that has ruler, compasses and protractor function concurrently, is the research of an outbalance.
Summary of the invention
Goal of the invention of the present invention is for a kind of multifunctional drawing ruler is provided, and it has the function that has ruler, compasses and protractor three concurrently, makes the mapping work simplification, uses flexibly.
Purpose of the present invention can be achieved through the following technical solutions.
A kind of multifunctional drawing ruler comprises:
One has the disk of 360 ° of angle indexs,
One has the ruler of length scale;
The center of described disk has a hole, and the less end of described ruler scale also is provided with a hole, and disk and ruler pass two holes by a rotating shaft, and ruler and disk can be rotated around this rotating shaft; The axis parallel with the ruler horizontal edge is provided with elongated slit.
Described ruler is provided with fixture, and fixture is enclosed within on the ruler, and controls the slip of fixture by a winding device; The position that overlaps with the slit on fixture is provided with circular hole.
Described ruler is fold mechanism or telescoping mechanism.
By the multifunctional drawing ruler that the present invention designs, simple in structure, easy to use, have ruler, compasses and protractor three's function concurrently, make the mapping work simplification, use flexibly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1-disk 2-ruler 3-rotating shaft
4-slit 5-fixture 6-circular hole
The specific embodiment
Further specify technical characterstic of the present invention below in conjunction with drawings and Examples.
A kind of multifunctional drawing ruler as shown in Figure 1 comprises: a disk 1, that has 360 ° of angle indexs has the ruler 2 of length scale; The center of described disk 1 has a hole, and the less end of described ruler 2 scales also is provided with a hole, and disk 1 and ruler 2 pass two holes by a rotating shaft 3, and ruler 2 and disk 1 can be rotated around this rotating shaft; The axis parallel with ruler 2 horizontal edges is provided with elongated slit 4.
Embodiment 1
Make equilateral triangle
1, uses the line segment of ruler 2 office's length;
2, with the left end point of the aligned line segment in the rotating shaft 3, rotation ruler 3 is measured 60 degree on disk 2, read unit length on ruler 3, uses pen at the slit of ruler 34 relevant position markings;
3, connect left end point and mark point;
4, connect right endpoint and mark point, finish the mapping of equilateral triangle.
Embodiment 2
Office's circle
1, determines the center of circle;
2, with the aligned center of circle of rotating shaft 3;
3, measure unit length with ruler 2, and mobile fixture 5 determines positions, making the length of the circular hole 6 of the center of circle to the fixture 5 is radius;
4, nib is inserted circular hole 6 on the fixture 5;
5, rotate ruler 2 one circles and obtain unit circle.
