Abstract
The utility model relates to a multipurpose angle ruler, including a ring and two rulers, wherein one end of a ruler is fixed on the ring, the other end fixed on the ring center; one end of another ruler is articulated on the ring center, while the other end is a movable end. The angle scales are disposed on the said ring. The length scale are disposed on the said two rulers. The utility model fixed one of the two new rulers on the ring, another is moveblely installed on the ring, and the scales are respectively engraved on the ring and the ruler, it can respectively measure the length and angle in accordance with need when used, and can measure the numerical value of side length of the angle. The utility model has features that it is simple in structure and easy-to-use.
Description
Technical field
The utility model relates to a kind of bevel protractor, specifically a kind of bevel protractors of using more.
Background technology
We know, the method for drawing angle at present in the hand-drawing generally is earlier with the ruler limit of drawing, and the angle of drawing and needing by protractor is not only time-consuming but also the error of generation is increased then, is unfavorable for improving mapping efficient.
The utility model content
The utility model provides a kind of simple in structure for overcoming above-mentioned the deficiencies in the prior art, the bevel protractor of using easy to use more.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of bevel protractors of using more, it includes an annulus and two rulers, one end of one of them ruler is fixed on the annulus, the other end is fixed on the center of circle of annulus, one end of another ruler is hinged on the center of circle of annulus, and the other end is a movable end.
Described annulus is provided with angle index.
Described two rulers are provided with the length scale.
The utility model adopts one in two rulers is fixed on the annulus, another is movably arranged on the annulus, and is carved with scale respectively on annulus and the ruler, during use, length and angle can be measured respectively as required, and the length of side numerical value of angle of departure can be measured.The utlity model has characteristics such as simple in structure, easy to use.
Description of drawings
Accompanying drawing is the utility model structural representation.
1. annulus, 2. ruler among the figure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment: structure as shown in drawings, it includes an annulus 1 and two rulers 2, and an end of one of them ruler 1 is fixed on the annulus 1, and the other end is fixed on the center of circle of annulus 1, one end of another ruler 2 is hinged on the center of circle of annulus 1, and the other end is a movable end.Be respectively equipped with angle index and length scale on described annulus 1 and two rulers 2.
Claims (3)
1. use bevel protractor one kind more, it includes an annulus and two rulers, it is characterized in that: an end of one of them ruler is fixed on the annulus, and the other end is fixed on the center of circle of annulus, one end of another ruler is hinged on the center of circle of annulus, and the other end is a movable end.
