Abstract

The utility model discloses a multifunctional ruler comprising a right angle triangular base plate. The multifunctional ruler is characterized in that the right-angle triangular base plate is provided with a compass, a protractor and a broken line drawing groove; a circle center foot of the compass is arranged at the right angle of the right angle triangular base plate, and the internal side of one right angle edge of the right-angle triangular base plate is provided with a line drawing foot movable narrow gap parallel to the edge; a central angle is positioned on an extension line of the line drawing foot movable narrow gap, a line drawing foot is movably arranged on the line drawing foot movable narrow gap, on which scales are arranged; the internal side of the other right-angle edge of the right-angle triangular base plate is provided with a broken line drawing groove; the bottom edge of the protractor and the inclined edge of the right-angle triangular base plate are parallelly arranged; and the center point of the bottom edge of the protractor is provided with a movable angle drawing ruler. The multifunctional ruler can be used for drawing various graphs only by using a drawing tool, thereby saving time and improving the learning efficiency, being convenient to be carried and difficult to be lost, having simple structure, and bringing great convenience to students.

Description

Multi-functional ruler-compasses

Technical field

The utility model belongs to the stationery technical field, is specifically related to a kind of multi-functional ruler-compasses.

Background technology

The student need use graphometer, set square, ruler when mapping, existing drawing tool all is separated from each other mostly, is used alternatingly very inconveniently, loses easily, but also lose time, so a kind of drawing tool that can gather multi-function in integral whole of necessary design.

Summary of the invention

The purpose of this utility model is to provide a kind of multi-functional ruler-compasses, to solve the problem of existing ruler function singleness.

The technical scheme that the utility model adopted is, a kind of multi-functional ruler-compasses, comprise the right angled triangle substrate, it is characterized in that right angled triangle substrate right angle top is equipped with center of circle pin near upright, center of circle pin is fixed by screw and nut, there is the movable slit of the setting-out pin that is parallel to this limit one right-angle side inboard of right angle trigonometry base board, movable slit of setting-out pin and central angle are on the same right-angle side of right angled triangle substrate, the setting-out pin is contained on the movable slit of setting-out pin by screw and nut and can be free to slide also and can fixes, the movable slit of setting-out pin top is the protractor scale, the another side inboard of right angled triangle substrate has dotted line to draw groove, and the movable angle square of drawing is equipped with in substrate center protractor straight line center.

The characteristics of the utility model multi-functional ruler-compasses also are,

The movable angle square of drawing is fixed by activity picture angle square fixed screw, on center of circle pin and the setting-out pin draw point and lead for retractable pencil is arranged respectively, and it is to have the slit that equidistantly distributes thin plastic boss that dotted line is drawn groove.

The beneficial effects of the utility model are, only with a drawing tool various figures that just can draw, have saved the time, have improved learning efficiency, and have been easy to carry, and are difficult for losing.

Description of drawings

Fig. 1 is the structural representation of the utility model multi-functional ruler-compasses;

Among the figure, 1. right angled triangle substrate, 2. protractor, the 3. movable angle square fixed screw of drawing, the 4. movable angle square of drawing, 5. dotted line is drawn groove, 6. setting-out pin, 7. setting-out pin fixed screw, 8. lead for retractable pencil, 9. the movable slit of setting-out pin, 10. center of circle pin, 11. center of circle pin fixed screw nuts, 12. draw points.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The utility model multi-functional ruler-compasses structural representation as shown in Figure 1, a kind of multi-functional ruler-compasses, comprise right angled triangle substrate 1, it is characterized in that, right angled triangle substrate 1 is provided with compasses, protractor 2 and dotted line are drawn groove 5, the center of circle pin 10 of compasses is arranged on place, right angled triangle substrate 1 right angle, center of circle pin 10 is fixing by center of circle thumb screw nut 11, there is the movable slit 9 of the setting-out pin that is parallel to this limit one right-angle side inboard of right angle trigonometry base board 1, central angle 10 is positioned on the extended line of the movable slit 9 of setting-out pin, setting-out pin 6 is movably arranged on the movable slit 9 of setting-out pin, the movable slit 9 of setting-out pin is provided with scale, be provided with dotted line in another right-angle side inboard of right angled triangle substrate 1 and draw groove 5, the hypotenuse of the base of protractor 2 and right angle trigonometry base board 1 be arranged in parallel, the scale of protractor 2 is towards two right-angle sides of right angle trigonometry base board 1, the base mid point of protractor 2 is provided with the movable angle square 4 of drawing, the movable angle square 4 of drawing is by screw 3 location, and movable scale indication end of drawing angle square 4 can be rotated along the scale graticule of protractor 2.

The characteristics of the utility model multi-functional ruler-compasses also are:

Be separately installed with draw point 12 and lead for retractable pencil 8 on center of circle pin 10 and the setting-out pin 6;

Be provided with equidistant barrier in the elongated slot of dotted line picture groove 5.

When drawing circle or drawing arc, as long as earlier mobile setting-out pin 6 is fixing to appropriate location rotary picture stitch fixed screw 7, the sharp snail of draw point 12 is aimed at the center of circle, the top rotation of hand-held substrate top gets final product, central angle 10,6 rotations of setting-out pin need not be fixed at ordinary times, as long as being drawn angle square 4, activity forwards the appropriate location on demand to when doing the angle, get final product along activity picture angle square 4 and protractor 2 bases picture with pen, the sideline that dotted line can be drawn groove 5 when drawing dotted line is put into the position that will draw dotted line, with along the sideline picture get final product standardized dotted line.

The utility model collection multi-functional ruler-compasses only needs a drawing tool various figures that just can draw, and has saved the time, has improved learning efficiency, and has been easy to carry, and is difficult for losing, and is simple in structure, brings great convenience to the student.
