Abstract
The utility model belongs to a multifunctional drawing rule among the drawing tool, it comprises two supporting rulers, has the function of drawing parallel line, perpendicular line, circle, curve, angulation and drawing small circle and special-shaped figure fast, is a simple structure, and processing is easy, carries, uses all more convenient be suitable for middle and primary school students and field drawing worker's multi-functional drawing rule of ideal.
Description
The utility model belongs to a kind of multifunctional drawing ruler in the drawing instrument.
Instruments such as existing drawing rule, plate, the adaptive surface of its single-piece function is narrower, must cooperate other drawing instrument such as compasses, protractor etc., just can finish drawing work, therefore, the numerous and diverse and inconvenience of using that causes drawing instrument to carry, and then have influence on plotting speed.
The purpose of this utility model provides a kind of portable, quick, multifunctional drawing ruler for addressing the above problem exactly.
Below in conjunction with accompanying drawing the utility model is described.
The utility model is by two four 1,2 supporting compositions of the graduated ruler of limit an ancient unit of weight, and the minor face of chi is big with the more general ruler on long limit.This design feature, the minor face that is suitable for a ruler can serve as to rely on parallel sliding with the long limit of another bar rule, mark a series of parallel lines or vertical line, and the combination of amount picture.Main scale 1 contains the picture round belting, draws round belting 16 and is respectively φ 0. by cover fillet 11, slideway 13, chi two ends diameter
5 millimeters, the lead for retractable pencil hole 15 of 0.7 millimeter of φ, 0.9 millimeter of φ, the locating piece 7 that can slide arbitrarily, radius rule 18 are formed.Locating piece 7 by draw point 10, spring 9, slide core 7, fasteningly emit 8 to form.Draw bowlder, unclamp and fasteningly emit 8, mobile slide core 7 is to the radius delineation position of rule 18, tightens then fasteningly to emit 8, and left hand is pressed draw point 10 in home position, and the right hand inserts pencil-lead in the lead for retractable pencil hole 15, rotates a week, and required circle promptly draws.Protractor 5, curve ruler 8, diameter are arranged from 0.2 millimeter circular hole 4 of φ, various irregularly-shaped hole 6 on the secondary chi 2 to 12 millimeters of φ.This design feature has protractor, curve ruler, draws the function of roundlet and irregularly-shaped hole fast.
This utility model, auxiliary equipment is few, and is simple in structure, portably uses all more conveniently, is a kind of pupils and students of being suitable for and field mapping worker's desirable multifunctional drawing ruler.
