Abstract
The invention discloses a ruler capable of measuring angles, which comprises: the first ruler is provided with length marks; the angle ruler is arranged at one end of the first straight tooth, and angle marks are engraved on the angle ruler; a second straightedge rotatably disposed at one end of the first straightedge and the angle scale is located on the underside of the second straightedge. This measurable quantity ruler for angle solves present ruler only the function of simple drawing the straight line and measuring, and needs the semicircle appearance more when needing to measure the angle and go on, needs ruler and the cooperation of semicircle appearance when the angle of a known angle of needs drawing, and whole process is very loaded down with trivial details problem.
Description
Technical Field
The invention belongs to the technical field of measuring tools and precision instruments, and particularly relates to a ruler capable of measuring angles.
Background
The usual mapping is mainly divided into length mapping and angle mapping, for which it is mainly done by a straight ruler, a tape measure and a tape measure, and for which it is mainly done by a semicircle meter mapping.
However, the existing ruler only has the functions of simply drawing a straight line and measuring, and a graphometer is needed to measure the angle. When an angle with a known angle needs to be drawn, the ruler and the graphometer need to be matched, and the whole process is very complicated.
Therefore, it is necessary to provide a ruler with an angle measurement function, which is convenient for people to use and improves the working efficiency.
Disclosure of Invention
The invention aims to provide a ruler capable of measuring angles, which solves the problems that the existing ruler only has the functions of simply drawing straight lines and measuring angles, but needs a graphometer to measure the angles, needs the cooperation of the ruler and the graphometer when an angle with a known angle needs to be drawn, and is very complicated in the whole process.
In order to achieve the purpose, the invention adopts the technical scheme that: a ruler for measuring angles, comprising:
the first ruler is provided with length marks;
the angle ruler is arranged at one end of the first straight tooth, and angle marks are engraved on the angle ruler;
a second straightedge rotatably disposed at one end of the first straightedge and the angle scale is located on the underside of the second straightedge.
The technical scheme of the invention also has the following characteristics:
as a preferable scheme of the technical scheme of the invention, the first ruler, the second ruler and the angle ruler are all white and transparent.
As a preferable scheme of the technical scheme of the invention, one end of the first ruler is provided with a fixing pin, and the second ruler is rotatably sleeved on the fixing pin.
As a preferable scheme of the technical scheme of the invention, the second ruler is provided with an installation hole, and the installation hole is internally provided with a magnifying lens.
As a preferable scheme of the technical scheme of the invention, the magnifying lens is made of glass.
Compared with the prior art, the ruler for measuring the angle has the advantages that: (1) the ruler capable of measuring the angle can be used for surveying and mapping a straight line by using the first straight ruler. (2) The ruler capable of measuring the angle can be used for surveying and mapping the angle by the first rulers and the second rulers, and a surveying and mapping result is displayed on the angle ruler. (3) The ruler capable of measuring the angle, disclosed by the invention, has the advantages of simple overall structure, convenience in operation, capability of simultaneously realizing linear and angle surveying and mapping, lower manufacturing cost and better market popularization and application prospects.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a working principle diagram of a ruler for measuring angles according to the present invention.
In the figure: 1. the ruler comprises a first straight ruler, 2 length marks, 3 a second straight ruler, 4 an angle ruler, 5 a magnifying lens, 6 a fixing pin and 7 angle marks.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a ruler for measuring an angle according to the present invention includes:
the first ruler 1 is provided with length marks 2;
the angle ruler 4 is arranged at one end of the first straight tooth 1, and angle marks 7 are carved on the angle ruler 4;
a second straightedge 3, the second straightedge 3 being rotatably arranged at one end of the first straightedge 1 and a bevel 4 being located at the lower side of the second straightedge 3.
When the ruler capable of measuring angles is used and a straight line needs to be drawn or the length of a line needs to be measured, the second ruler 3 is overlapped with the first ruler 1, and the straight line is drawn or the length of the line is measured through scales on the first ruler 1. When the angle needs to be measured, the first straight ruler 1 is enabled to be attached to one side of the angle, the second straight ruler 3 is adjusted to enable the other side of the auxiliary ruler to be attached to the angle, and the size of the angle can be read out by observing the scales of the angle ruler 4. When the angle needs to be drawn, the second ruler 3 is adjusted to the corresponding scale, and then the angle of the known angle can be drawn through the first ruler 1 and the second ruler 3.
As shown in figure 1, the first ruler 1, the second ruler 3 and the angle ruler 4 are white and transparent, and scales can be observed conveniently.
As shown in figure 1, according to the ruler capable of measuring angles, the fixing pin 6 is arranged at one end of the first ruler 1, and the second ruler 3 is rotatably sleeved on the fixing pin 6, so that rotatable assembly can be achieved.
As shown in fig. 1, in the ruler for measuring an angle of the present invention, the second ruler 3 is provided with a mounting hole, the mounting hole is provided with a magnifying lens 5, the magnifying lens 5 has a scale mark, and the aligned scale is the angle value, and the angle mark 7 at this time needs to be rearranged according to the scale mark in the magnifying lens 5.
As shown in FIG. 1, the ruler for measuring angles of the present invention has a magnifying glass 5 made of glass for easy scale observation.
In summary, compared with the prior art, the ruler for measuring angles has the following advantages: (1) the ruler capable of measuring the angle can be used for surveying and mapping a straight line by using the first straight ruler. (2) The ruler capable of measuring the angle can be used for surveying and mapping the angle by the first rulers and the second rulers, and a surveying and mapping result is displayed on the angle ruler. (3) The ruler capable of measuring the angle, disclosed by the invention, has the advantages of simple overall structure, convenience in operation, capability of simultaneously realizing linear and angle surveying and mapping, lower manufacturing cost and better market popularization and application prospects.
