Abstract
The utility model relates to an angle gauge with a ruler, which is a hollow angle gauge; the angle gauge is characterized in that the straight side on the hollow angle gauge (1) is provided with the ruler (2); and one end of the ruler (2) is movably connected with the center of the straight side by a rotating shaft. The angle gauge has simple structure, is convenient to be used, can not only precisely measure angles, but also conveniently draw angles and plane figures with specified angles.
Description
Technical field
The utility model relates to study article, particularly a kind of protractor with ruler.
Background technology
Common protractor function singleness can only be used for taking measurement of an angle, or draws some simple straight line and camber lines.When taking measurement of an angle, measure inaccurate because of the error of eyes through regular meeting; When needs were drawn angle and specified angle drafting triangle or polygon, common protractor and ruler neither be very suitable.
Summary of the invention
The purpose of this utility model provides a kind of can accurately taking measurement of an angle, and can make things convenient for the protractor of the band ruler of angle drafting.
The protractor of described band ruler is a hollow protractor, it is characterized in that: establish a ruler on the straight flange of hollow protractor, an end of ruler and the center of straight flange flexibly connect by rotating shaft.
The utility model is simple in structure, and is easy to use, and both sizes that can take measurement of an angle accurately can also conveniently be drawn the planar graph of angle and specified angle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-hollow protractor, 2-ruler.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Among Fig. 1, the protractor of described band ruler is a hollow protractor, it is characterized in that: establish a ruler 2 on the straight flange of hollow protractor 1, an end of ruler 2 and the center of straight flange flexibly connect by rotating shaft.The both sides of ruler 2 all are provided with scale, can rotate around rotating shaft, and when taking measurement of an angle, ruler 2 can be used as a pointer, points out the value of angle accurately.Because protractor is a hollow, the corresponding angle of can drawing according to the number of degrees of ruler 2 indications can be used for drawing the angle of specifying the number of degrees and contains the planar graph of angle with other.Ruler 2 can be rotated to the below of protractor, draws the angle or works as common ruler use.
Claims (1)
1. the protractor with ruler is a hollow protractor, it is characterized in that: establish a ruler (2) on the straight flange of hollow protractor (1), an end of ruler (2) and the center of straight flange flexibly connect by rotating shaft.
