Abstract

The utility model discloses a multifunctional set square which comprises a set square body, a narrow circular groove 2 and a wide circular groove 3. The narrow circular groove 2 and the wide circular groove 3 are arranged in the set square body sequentially from outside to inside. Standard graphs 4 and graduated elongated slots 1 are reserved in the wide circular groove 3, and the elongated slots 1 penetrate through the narrow circular groove 2 and the wide circular groove 3. Production materials of the set square are reduced greatly while original functions of the set square are reserved. Plastic material for making a common set square is reduced by more than 30%. Functions of drawing a circle, a triangle, a five-pointed star, a regular hexagon, a 45-degree section line, a 90-degree perpendicular line and a 135-degree section line are added. In addition, area of contact of the set square with graph paper is reduced, pollution of the graph paper drawn on with the set square can be reduced greatly, and the graph paper is kept clean. The drawing functions of the set square can be increased. The multifunctional set square is simple in structure.

Description

A kind of multifunctional triangle

Technical field

The utility model relates to a kind of drawing instrument, is specially a kind of saving manufactured materials, can draw multiple machanical drawing commonly used, and can when the profile drawing line, reduce the multifunctional triangle that causes drawing to pollute because of the translation set square.

Background technology

Set square is the modal learning tool of student, especially the indispensable drawing tool of university's industry science student.At present, set square structure commonly used is that thickness is even, and there is the hole of suitable size the centre, makes things convenient for user's grasping and moves.But the waste of material therefor when this structure has caused the non-key position of set square to make does not meet the policy of the green energy conservation that country advocated.Common set square graphing is comparatively single, can only draw simple line pattern mostly, can not draw various polygons commonly used and circle.When set square collocation T-square is drawn the part hatching; Because the set square bottom surface contacts with drawing fully, causes the set square bottom surface to scratch the black-lead pen and ink on the drawing, when set square is moved further; Cause of the pollution of pencil China ink, influence the visual effect of drawing drawing.

Therefore, providing a kind of and can save material, avoid because of the mobile drive pencil China ink of set square drawing being polluted, and have the multifunctional triangle of multiple function, has been a problem of needing solution badly.

Summary of the invention

In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of Multifunction set square of making plastic material, the function that increases the set square graphing of using set square always and reducing the drawing pollution that is caused when using set square to draw of saving.

The purpose of the utility model is achieved in that

Multifunctional triangle comprises the set square plate body, and the thin cannelure 2 that in the set square plate body, sets gradually from outside to inside, wide cannelure 3.

In wide cannelure 3, also be provided with test pattern 4, and be positioned at the elongated slot that has scale 1 that runs through thin cannelure 2 and wide cannelure 3;

Described test pattern 4 is circle, triangle, five-pointed star, regular hexagon, the ellipse of hollow;

Described wide cannelure 3 inwardly can also be provided with protractor 5,7,135 ° of angles 8,6,90 ° of angles of 45, and is positioned at the circular hole that is spaced apart 1mm 9 on protractor 5, the 8 common bases, 7,135 ° of angles, 6,90 ° of angles of 45;

7,135 ° of angles 8,6,90 ° of angles of described 45, and another limit that the common base with them that is positioned at protractor 5,7,135 ° of angles 8,6,90 ° of angles of 45 forms angle is provided with scale;

7,135 ° of angles 8,6,90 ° of angles of described 45, and the segment 10 that between protractor 5,7,135 ° of angles 8,6,90 ° of angles of 45 and protractor 5, is divided into is hollow form;

Positive beneficial effect: the utility model patent provides a kind of novel set square; Can be on the basis that keeps the set square original function; Significantly reduce the material of making set square; Saving is made the plastic material of set square commonly used more than 30%, and has increased the drafting function of circle, triangle, five-pointed star, regular hexagon, 45 ° of hatchings, 90 ° of vertical lines and 135 ° of hatchings, reduces the contact area of set square and drawing simultaneously; To the pollution that drawing caused, play the effect of clean drawing in the time of significantly reducing the drawing of use set square; Can also increase the drawing function of set square, and simple in structure.

Fig. 3 is that the master of 60 ° of set squares looks and sectional structure chart;

Fig. 4 is that the B-B ‵ of Fig. 3 is to cross-sectional view;

Elongated slot 1 among the figure. thin cannelure 2, wide cannelure 3, test pattern 4, protractor 5,7,10.135 ° of angles 8,6,90 ° of angles of 45, circular hole 9, segment 10.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described:

Like Fig. 1, shown in Figure 2, in wide cannelure 3, also be provided with test pattern 4, and be positioned at the elongated slot that has scale 1 that runs through thin cannelure 2 and wide cannelure 3;

As shown in Figure 1, described test pattern 4 is circle, triangle, five-pointed star, regular hexagon, the ellipse of hollow;

Like Fig. 3, shown in Figure 4; Described wide cannelure 3 inwardly can also be provided with protractor 5,7,135 ° of angles 8,6,90 ° of angles of 45; And be positioned at the circular hole that is spaced apart 1mm 9 on protractor 5, the 8 common bases, 7,135 ° of angles, 6,90 ° of angles of 45, can be used the circle of drawing different radii);

In the entity of set square commonly used, leave the part groove, outside guaranteeing the required necessary rigidity of set square drawing, reduce the material use amount of non-key structure division, reach the purpose of saving manufactured materials.Simultaneously, when the method can significantly reduce set square and moves and the drawing surface contact area, scratch the black-lead pen and ink amount on the drawing, cleaned drawing thereby reduce the set square bottom surface.On set square, be provided with circle commonly used, triangle, five-pointed star, regular hexagon, 45 ° of hatchings, 90 ° of vertical lines and 135 ° of hatching figures simultaneously, the various required figures of convenient drafting, easy to use.

The utility model patent provides a kind of novel set square; Can be on the basis that keeps the set square original function; Significantly reduce the material of making set square; Saving is made the plastic material of set square commonly used more than 30%, and has increased the drafting function of circle, triangle, five-pointed star, regular hexagon, 45 ° of hatchings, 90 ° of vertical lines and 135 ° of hatchings, reduces the contact area of set square and drawing simultaneously; To the pollution that drawing caused, play the effect of clean drawing in the time of significantly reducing the drawing of use set square; Can also increase the drawing function of set square, and simple in structure.

Above embodiment only is used to explain the preferred implementation of the utility model; But the utility model is not limited to above-mentioned embodiment; In the ken that said field those of ordinary skill is possessed; Any modification of being done within spirit of the utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technical scheme scope that the utility model asks for protection.
