Description

Multipurpose ruler

The utility model relates to a kind of multipurpose ruler, is used for drawing or study, belongs to the cultural goods field.

Known various drafting instruments have ruler, angle square, compasses etc. at present, and some dual-purpose or use drawing instruments are also arranged more, but undesirable, therefore are necessary the desirable multipurpose ruler that an a kind of tool of utility model is used more, make things convenient for everybody working and learning.

The purpose of this utility model provides a kind of multipurpose ruler that integrates ruler, angle square and compasses etc., like this because the many usefulness of a tool have been brought convenience to drawing.

The purpose of this utility model is achieved in that on the ruler that makes with transparent material the graduation mark with every centimetre extends to the ruler another side, this extended line and ruler edge line become the right angle, be right-angle line, as long as this right-angle line is pressed on the straight line of having drawn, the edge line of its chi and its right-angle line promptly meet at right angles, and have so just realized the function that angle square and ruler are total.The circular hole slotted eye that be provided with semicircle orifice everywhere again in chi, varies in size can draw round and oval, in same line, be provided with small sircle hole in addition, utilization needs two small sircle holes of radius length, one is central point, one is circumference, nib inserts rotation multipurpose ruler in the selected circumferential apertures, and circumference can draw.For convenience, accurately find out the position of parallel lines, be marked with millimeter and centimeter scale, and be to interlock oppositely to mark, be convenient to determine, become the parallel graduation mark that picture equates parallel lines at several places right-angle line.Also the end at multipurpose ruler is provided with protractor.

Owing to adopted such scheme, on this bar rule, just has the function of the draw tool of ruler, angle square, protractor, compasses and parallel lines, one-object-many-purposes, convenient being suitable for.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the multipurpose ruler schematic diagram.

Fig. 2 is used for compasses and draws oval functional schematic in the multipurpose ruler.

1 right-angle line position among the figure, 2 straight line positions, 3 parallel lines positions, 4 draw circle line position, 5 protractor positions, 6 circle holes, 7 two-point drawing circular holes, 8 semicircle orifices, 9 elliptical apertures.

In Fig. 1, utilize right-angle line position 1 and straight line position 2 right-angle line that can draw; With the straight line that can draw with straight line position 2; Utilize parallel lines position 3 and the straight line position 2 equal parallel lines that can draw; Utilize the protractor position 5 among the figure to replace protractor; Circle hole 6,2 circular holes 7 and semicircle orifice 8 all are the picture circle line positions of using as compasses 4, and can the draw semicircle of two kinds of different radiis of the circumference that utilizes circle hole 6 and two-point drawing circular hole 7 can draw and vary in size, semicircle orifice 8 utilizes elliptical aperture 9 ellipse that can draw.

Claims (3)

1, a kind of multipurpose ruler that makes with transparent material is characterized in that: the another side that every centimetre graduation mark extends to chi is a right-angle line, becomes the right angle with the edge line of chi; There are several right-angle lines to indicate reverse scale; The centre has circle hole and two-point drawing circular hole, semicircle orifice, and elliptical aperture is provided with protractor at an end of multipurpose ruler.

2, multipurpose ruler according to claim 1 is characterized in that: right angle graduation mark institute target yardstick graduation mark oppositely staggers and marks.

3, multipurpose ruler according to claim 1 is characterized in that: there are two-point drawing line hole, many places, circle hole, semicircle orifice and elliptical aperture in the compasses hole.
