Description

A kind of multifunctional drawing template

Technical field

The utility model relates to a kind of drawing instrument.

Background technology

As everyone knows, in recent years, a lot of drawing templates for senior middle school, university student's design are arranged on the market, but the following drawback of these template ubiquities: there is figure a lot of and that the content of courses is irrelevant in (1) template, causes utilization rate lower.(2) when drawing ellipse, circle, parabola figures, can not find suitable dimensions, draw accurate inadequately with template.(3) it is comparatively single to contain graph style, lacks figure commonly used in many drawing.

Summary of the invention

The purpose of the utility model has overcome above-mentioned said deficiency, provides that a kind of to contain graph style comprehensive, the required figure of drafting that can be more accurately and fast, simple to operate flexibly, be suitable for the multifunctional drawing template of extensively promoting.

The utility model solves the technical scheme that its technical problem adopted: template is a plate-like structure, is processed by transparent or semitransparent plastics, and template surface is provided with concentric grooves; The concentration ellipse groove, parabola groove, hyperbola groove; Computer marking examination card-coating nib is just waiting and is surveying reference axis groove, oblique two and survey the series plot grooves and have two two oval grooves that overlap end points, and wherein oblique two survey the series plot grooves comprises that oblique two survey equilateral triangles, oblique two and survey positive five, the hexagon of square and oblique two surveys; Both sides, template upper end are respectively equipped with protractor and oblique two and survey reference axis; The template edge is pressed into the SIN function curve, cotangent function curve, the shape of logarithmic function curve; The template bottom is provided with the length scale, and the template bottom is provided with curve ruler for one jiao.

Said concentration ellipse groove is surveyed ellipse for just waiting.

Said two oval grooves are different with concentration ellipse groove eccentricity.

Just waiting survey reference axis groove to form with the bisector at said two exterior angles that adjacent edge becomes by orthohexagonal two adjacent edges.

The length scale of the said oblique two survey reference axis longitudinal axis is represented 1 centimetre for 0.5 centimetre.

The operating process of the utility model is: when graphing; The user can insert nib to move in the groove of institute's drawing shape and along its edge and get final product, and utilizes template can draw concentric circles, concentration ellipse, parabola, hyperbola, SIN function curve, cotangent function curve; Logarithmic function curve and oblique two is surveyed the figure that the technique of painting is drawn; Oblique two survey reference axis and are just waiting the survey reference axis and just waiting the survey technique of painting to facilitate for the oblique two survey techniques of painting, and template also has linear measure longimetry and the function of drawing the different curvature curve, when taking an examination; Computer marking examination card-coating nib capable of using carries out full-filling, can in the standard full-filling, save time.

The utility model compared with prior art has following advantage:

1, it is comprehensive to contain graph style, is suitable for the drafting of a plurality of figures commonly used in the multi-door subjects such as algebraically, how much, mechanical drawing.

2, the required figure of drafting that can be more accurately and fast, simple to operate flexibly, for the user saves the plenty of time, improve drawing efficiency.

3, compact conformation, technology is simple, and low preparation cost is suitable for extensive popularization.

Description of drawingsFig. 1 is the main TV structure simplified schematic diagram of the utility model.

The specific embodimentIn the main TV structure simplified schematic diagram of the utility model shown in Figure 1, template is a plate-like structure, is processed by transparent or semitransparent plastics; Template 1 surface is provided with concentric grooves 2, concentration ellipse groove 3, parabola groove 4; Hyperbola groove 5, computer marking examination card-coating nib 6 is just waiting and is surveying the two oval grooves 8 that reference axis groove 7, oblique two is surveyed the series plot groove and had two coincidence end points; Wherein oblique two survey the series plot grooves comprises that oblique two survey equilateral triangles 9, oblique two and survey square 10 and oblique two and survey positive five, hexagon, and both sides, template 1 upper end are respectively equipped with protractor 11 and survey reference axis 12 with oblique two, and template 1 edge is pressed into SIN function curve 13; Cotangent function curve 14; The shape of logarithmic function curve 17, template 1 bottom is provided with length scale 15, and template 1 bottom is provided with curve ruler 16 for one jiao; Concentration ellipse groove 3 is surveyed ellipse for just waiting; Two oval grooves 8 are different with concentration ellipse groove 3 eccentricities, just waiting survey reference axis groove 7 to be made up of with the bisector at said two exterior angles that adjacent edge becomes orthohexagonal two adjacent edges, and the length scale of oblique two survey reference axis, 12 longitudinal axis is represented 1 centimetre for 0.5 centimetre.

The user can utilize concentric grooves 2 to draw the circle and the ellipse of different sizes with concentration ellipse groove 3; Utilize parabola groove 4, hyperbola groove 5 is drawn parabola and hyperbola respectively, and oblique two survey the series plot groove can draw oblique two mapping shapes commonly used fast; Oblique two survey reference axis 12 surveys reference axis groove 7 and is respectively the oblique two survey techniques of painting and is just waiting the survey technique of painting to facilitate with just waiting; Along the SIN function curve 13 at template edge, cotangent function curve 14, the shape of logarithmic function curve 17 is drawn the respective function curve; Can accomplish fast; For doing topic and the quality time is saved in study, draw the curve of different curvature if desired and can accomplish by curve ruler 16, can carry out full-filling by the computer marking card-coating nib 6 of taking an examination during examination.
