Abstract

The utility model discloses a multifunctional simple drawing angle gauge which comprises a transparent hard material, a linear scale mark, a parallel gap scale mark and an angle scale mark, wherein, the lineal scale mark, the parallel gap scale mark and the angle scale mark are arranged on the edge of the material; the parallel gap scale mark is perpendicular to the linear scale mark, and the angle scale mark is in a radiating shape by taking the center of the lineal scale mark as the center of a circle. An extension line, a vertical line, parallel line and a special included angle line of a generatrix are drawn by coinciding various scale marks with the generatrix on the plane, meanwhile, the positions and the lengths generated by various line sections can be designated. The linear scale mark, the parallel gap scale mark and the angle scale mark are arranged on the same material by arrangement, thereby solving the problems of the prior drawing that various tools such as a ruler, a deltoid plate and a protractor are needed and labor and time of the drawing process are consumed.

Description

Multifunction simple drawing angle square

Technical field

The utility model relates to a kind of instrument that is used for drawing geometric figures, is specifically related to a kind of drafting instrument of quick drawing geometric figures of extended line, vertical line, parallel lines and the certain degree line that can draw the plane Up Highway UHW.

Background technology

Because the needs of drawing need have suitable drafting instrument usually.As shown in Figure 1, be a kind of used straight line drafting instrument.This instrument comprises a hard material 10a, is printed on scale 11a on this material.Can be used for drawing the length-specific line segment, and prolong known line segment.But can not be comprehensive many-sided the survey tool of various needs be one, inconvenience during use.

Ruler is the scale that utilizes the hard material flattened edge and be printed on it, and draws the length-specific line segment.But when drawing general geometric figure, need to draw the vertical line, specific distance parallel lines, certain degree line of known bus etc. usually, above-mentioned lines all can't utilize existing ruler to draw.Promptly use instruments such as set square, protractor,, cause the inconvenience of carrying, time-consuming shortcoming in the drawing process though can reach above-mentioned purpose.

Summary of the invention

The purpose of this utility model is to provide a kind of multifunction simple drawing angle square.

For reaching above-mentioned purpose, the concrete content of the utility model is:

A kind of instrument that is used for drawing geometric figures, the ruler for transparent hard material is made indicates comprising a slide-rule dial that is printed on edge of materials; Other is provided with the parallel distance scale and indicates, and this parallel distance scale indicates vertical with the slide-rule dial sign.

Wherein this transparent hard material surface is provided with angle index in addition and indicates, this angle index indicate with slide-rule dial indicate a bit to be that the center of circle is radial.

Wherein this angle index sign is the radial center of circle with the mid point that slide-rule dial indicates.

Wherein slide-rule dial indicates, the parallel distance scale indicates and angle index is denoted as the printed layers that invests on the transparent hard material.

The utility model also comprises a kind of instrument that is used for drawing geometric figures, and the ruler for transparent hard material is made indicates comprising a slide-rule dial that is printed on edge of materials; Other is provided with angle index and indicates, angle index indicate with slide-rule dial indicate a bit to be that the center of circle is radial.

Wherein this transparent hard material surface is printed on parallel distance scale sign, and indicates vertical with slide-rule dial.

The utility model combine existing with functions such as rulers, set square, protractor in one, indicate by the various scale on the transparent hard material, be used for drawing the extended line, vertical line, parallel lines, certain degree line of bus etc., and then form various geometric figure.Therefore can reduce the trouble of replacing instrument, and reduce plot step, increase drawing efficiency and accuracy effectively.

The specific embodiment

Below the effect forming and can produce with regard to the structure of the utility model multifunction simple drawing angle square, conjunction with figs. is described in detail as follows with preferred embodiment:

See also Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the utility model provides a kind of instrument that is used for drawing geometric figures, slide-rule dial sign 11, parallel

distance scale sign

12,13 compositions of angle index sign that this instrument includes transparent hard material 10 and is printed on it.Slide-rule dial indicates 11 and places transparent hard material 10 flattened edge, and the parallel distance scale indicates 12 and indicates 11 vertically with slide-rule dial, and it is that the center of circle is radial placement that angle index indicates 13 mid points with slide-rule dial sign 11.

Fig. 3 is for drawing the schematic diagram of bus extended line: scheming short-and-medium grid dotted line is known bus, and transparent hard material 10 imbricates on bus, are aimed at the straight line graduated scale and shown 11, can draw the length-specific extended line, and this schematic diagram example is for prolonging 4.5 centimeters.

Fig. 4 is for drawing the schematic diagram of bus vertical line: scheming short-and-medium grid dotted line is known bus, angle index is indicated 13 90 degree graduation marks to be overlapped on the bus, transparent hard material 10 imbricates produce the position in institute's desire, utilize slide-rule dial to indicate 11, can draw the length-specific vertical line, this schematic diagram example is 4 centimeters vertical lines.

Fig. 5 is for drawing the schematic diagram of bus parallel lines: scheming short-and-medium grid dotted line is known bus, the parallel distance scale is indicated 12 to be overlapped on the bus, utilize slide-rule dial to indicate 11, can draw specific interval and length-specific parallel lines, this schematic diagram example is 1.5 centimeters of spacings, long 3 centimeters parallel lines.

Fig. 6 is for drawing the schematic diagram of bus certain degree line: scheming short-and-medium grid dotted line is known bus, institute's desire is drawn angle index sign 13 to be overlapped on the bus, transparent hard material edge 10 is overlapped in institute's desire and produces the position, utilize slide-rule dial to indicate 11, can draw the certain degree line of length-specific, this schematic diagram example is angle 60 degree, 3 centimeters angle lines of length.
