Abstract

The utility model provides a multifunctional drawing ruler for helping students to draw. The multifunctional drawing ruler mainly solves the problem of the prior student drawing tool that a three-dimensional geometric figure can not be drawn simply and rapidly. The multifunctional drawing ruler is characterized in that a ruler body is drawn with three-dimensional geometric figures, the periphery lines of the figures are hollowed out, and a plurality of hollow-out points are distributed on the center line perpendicular to the bottom surface according to a staff gauge in an equidistant way. The multifunctional drawing ruler can ensure that a user can draw the standard three-dimensional figure simply and rapidly and has the characteristics of convenient use and accurate location.

Description

Multifunctional drawing ruler

Technical field:

The utility model relates to a kind of student and uses the assisted mapping instrument, specifically relates to a kind of drafting instrument that is used to make the solid geometry figure.

Background technology:

Various rulers, tape measure and set square have been widely used in student's the drawing course at present, but in use find, these existing drafting instruments simple and fast very during for the straight line of drawing the plane, but when drawing the solid geometry figure, but often allow the user can not draw the very solid geometry figure of standard owing to can not accurately locate.

The utility model content:

For solve existing student with drawing instrument can not simple and fast the problem of the solid geometry figure that draws, the utility model provides a kind of multifunctional drawing ruler, this kind multifunctional drawing ruler can allow the very quick and easy very solid geometry figure of standard that draws of user, has characteristics easy to use, accurate positioning.

The technical solution of the utility model is: this kind multifunctional drawing ruler, comprise a blade that is carved with scale, wherein on described blade, be painted with the solid geometry figure, the periphery sideline hollow out of described figure, some somes hollow outs that equidistantly distribute by scale on its bottom surface vertical center line.

The utlity model has following beneficial effect: because this kind multifunctional ruler is painted with the solid geometry figure on described blade, the periphery sideline hollow out of described figure, some somes hollow outs that equidistantly distribute by scale on its bottom surface vertical center line, the student is when drawing, only the dimension of picture that need draw as required chooses corresponding sideline and the point that is positioned on the center line, use drawing pen along the sideline paddling of hollow out and with center line on the some line, any solid geometry figure that has been inscribed on this drawing rule easily just can draw.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the schematic diagram that utilizes the utility model mapping.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, this kind multifunctional drawing ruler comprises a blade that is carved with scale, wherein is painted with the solid geometry figure on described blade, the periphery sideline hollow out of described figure, some somes hollow outs that equidistantly distribute by scale on its bottom surface vertical center line.The figure that is carved with on the ruler shown in Fig. 1 is cuboid and cylinder, utilizes these two figures can draw cuboid, tetrahedron, rectangular pyramid, cylinder, prism, pyramid etc.Be a slight example shown in Fig. 1, can be made in a variety of geometric figures like this on this kind ruler as required.In addition, can on each sideline, add high scale, the mapping of being more convenient for like this.

This kind of multifunctional ruler can use the solid geometry figure of the different angles of so just drawing by tow sides.

In addition, as optimizing embodiment, can on described blade, design an X, y-line battle array, as shown in Figure 1, in this battle array, equidistantly distribute some X, y-line by scale, with any two X, y-line intersection hollow out, so just can be according to the hollow out point on the point draw easily sine, cosine, tangent, cotangent, ellipse, parabola and hyperbola.

Once more, can on described blade, portray a dihedral angle set that comprises 90 degree, 30 degree, 60 degree, 45 degree, 150 degree, all the periphery sideline hollow outs in this set, the dihedral angle of 30 degree that can draw like this, 45 degree, 60 degree and 90 degree.

Fig. 2 is a signal that utilizes this kind multifunctional ruler to draw.

If the expansion of this kind multifunctional ruler can also be increased a protractor at the one end, and the solid geometry formula of in the printing of the corresponding position of blade, being correlated with.

Claims (4)

1, a kind of multifunctional drawing ruler comprises a blade that is carved with scale, it is characterized in that: be painted with the solid geometry figure on described blade, the periphery sideline hollow out of described figure, some somes hollow outs that equidistantly distribute by scale on its bottom surface vertical center line.

2, multifunctional drawing ruler according to claim 1 is characterized in that: also have an X, y-line battle array on the described blade, equidistantly distribute some X, y-line by scale, any two X, y-line intersection hollow out.

3, multifunctional drawing ruler according to claim 1 and 2 is characterized in that: also have a dihedral angle set that comprises 90 degree, 30 degree, 60 degree, 45 degree, 150 degree on the described blade, all the periphery sideline hollow outs in this set.

4, multifunctional drawing ruler according to claim 3 is characterized in that: also have a protractor on the described blade.
