Abstract

A multifunctional drawing ruler comprises a stepped ruler board body, wherein the stepped ruler board body comprises a flat ruler part and a bevel gauge part, the flat ruler part is provided with a sliding body which can slide relative to the flat ruler part, the sliding body is fixedly provided with a drawing pen, the original point of the bevel gauge part is arranged on the flat ruler part, a circle centre foot pin is arranged on the original point, the circle centre foot pin and the drawing pen are located on a same horizontal line, when drawing a circle, the circle centre foot pin is fixed, the sliding body is moved to a setting distance, a fixed bolt is screwed, and then the multifunctional drawing ruler is rotated, which can finish the process of drawing the circle, when measuring an angle, only the circle centre foot pin is fixed on the base line of the to-be-measure angle, and then the angle can be measured. The multifunctional drawing ruler not only can measure angles, but also can draw circles, reduces the number of drawing tools in the drawing process, and facilitates the drawing.

Description

A kind of multifunctional drawing ruler

Technical field

The utility model relates to the drawing instrument of using in a kind of teaching process, particularly a kind of multifunctional drawing ruler.

Background technology

All only possess a kind of function at instruments such as present known drawing instrument such as protractor, compasses, rulers, draw circle and measuring angle and need use compasses and protractor, draw a figure and often will prepare multiple drawing instrument, to charting and teaching brings many inconvenience.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of a kind of multi-functional function drawing rule with picture circle and measuring angle function at the deficiencies in the prior art.

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of multi-functional function drawing rule, comprise step-like chi plate body, described step-like chi plate body comprises ruler portion and protractor portion, described ruler portion is provided with the slide mass that can slide relatively along ruler portion, described slide mass is fixed with paintbrush, the initial point of described protractor portion is located in the ruler portion, and the initial point place establishes center of circle pin pin, and center of circle pin pin and paintbrush are on same horizontal line.

Below be to further improvement in the technical proposal:

Have medial launder in the described ruler portion, the side of ruler portion has T type groove.

Described slide mass has can be along the T type portion and the sliding panel of T type groove slip, and described slide mass is provided with reading hole and set bolt.

Described ruler portion is provided with scale.

Adopt technique scheme, draw bowlder, center of circle pin pin is fixed, mobile slide mass screws set bolt to the distance of setting, and the multifunctional rotary drawing rule is promptly finished picture circle process then; Only need during measuring angle center of circle pin pin is fixed on the baseline of the angle that will measure and can measure angle, the utility model not only can be measured angle but also can be drawn circle, has reduced the drawing instrument quantity that needs in the picture process, has made things convenient for drawing.

Come the technical solution of the utility model is further described below in conjunction with drawings and Examples:
