Abstract

The utility model discloses a multi -functional portable set square belongs to graphics primitive technical field, the main scale of scale is indicated including two right -angle sides, be interior triangle frame in the main scale, still be equipped with the protractor in the interior triangle frame and indicate the scale, be equipped with 45 degrees chis with the protractor simultaneously with sharing partial area. The set square of this technical scheme through with two kinds of angles and protractor integration when the number of packages need be carried to reductions, can realize respectively partly original function totally in a set square, and saved the time that selection, arrangement consumed consequently, saved the space of the box of fit -up man utensil, the while is the raw and other materials manufactured of reducible its also to save the ample resources.

Description

A kind of multifunctional portable set square

Technical field

The utility model belongs to drawing instrument technical field, relates to a kind of drawing and measuring set square, especially relates to a kind of multifunctional portable set square.

Background technology

Basic a set of plane geometry drawing tool is generally containing set square two, and one is that one is isosceles right angle triangles containing 30 degree of set squares with 60 degree; Then a protractor, compasses, form family of four dress.

The plane geometry drawing tool of student is general all together with other schooling apparatus, loads, first will open writing case during use, then select required schooling apparatus and drawing tool to use as required with a writing case.If only select a drawing tool, can be more convenient, but in most cases, all need more than one piece instrument to convert or combine mapping.By chi thickness 1.5mm, if add ruler, only drawing tool thickness superposes all 6mm, greatly occupy writing case space, or select very large very thick writing case, or when drawing tool being put back to after being finished, must put according to the position of its regulation therefore, otherwise just put and do not go back, writing case does not close yet.Because drawing tool and schooling apparatus kind are too many, many times desk is everywhere stationery, waste time when this just makes schooling apparatus select, during study, notice is easily disperseed, and easily loses when tidying up after using, and impact uses next time.

The plane geometry drawing tool of teacher also includes the teaching aids such as set square, protractor, compasses, if a class only uses one or two pieces stationery, still eaily.If a class needs to use more than one piece drawing tool, will be not too convenient, especially carry cumbersome.

Utility model content

In order to solve the problem, the utility model provides a kind of multifunctional portable set square, thus reaches easy to use, holds portative effect.

The utility model is achieved by following technical solution.

A kind of multifunctional portable set square, comprises the graduated main scale of two right-angle side marks, be Triangle ID frame, be also provided with protractor and indicate scale in described Triangle ID frame in described main scale, while with protractor common sparing area be provided with 45 degree of chis.

Further, described protractor is with main scale Triangle ID frame two right-angle side intersection point for the center of circle, and its range is 90 °.

Further, described 45 degree of chis are using main scale Triangle ID frame two right-angle side as right-angle side.

Further, between described protractor inner arc and main scale Triangle ID frame right-angle side, and the space that the hypotenuse of 45 degree of chis and protractor arc-shaped side, each limit of main scale Triangle ID frame surround is engraved structure.

The beneficial effects of the utility model are:

A kind of multifunctional portable set square described in the utility model, by the set square of two kinds of angles and protractor being integrated in a set square, while minimizing needs to carry number of packages, can be completely achieved each several part original function; Therefore save selection, arrange the time consumed, save the space of the box of holding tool, also can reduce its raw material manufactured simultaneously, thus save ample resources.

Accompanying drawing explanation

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

In figure: 1-main scale, 2-protractor, 3-45 degree chi, 4-Triangle ID frame.

Detailed description of the invention

The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.

As shown in Figure 1, a kind of multifunctional portable set square described in the utility model, be integrate containing 30 degree with the drawing square of 60 degree, the isosceles drawing square of 45 degree, the 26S Proteasome Structure and Function of protractor, a kind of plane geometry drawing tool obtained through appropriate design, comprise the graduated main scale 1 of two right-angle side marks, be Triangle ID frame 4 in described main scale 1, be also provided with protractor 2 in described Triangle ID frame 4 and indicate scale, while with protractor 2 common sparing area be provided with 45 degree of chis 3.

Described protractor 2 is with main scale 1 Triangle ID frame two right-angle side intersection point for the arc center of circle, and its scale range is 90 °, directly can measure the angle of any acute angle, and the mode of supplementary angle angle by measuring obtuse angle obtains the angle at any obtuse angle.

Described 45 degree of chis 3 are using main scale 1 Triangle ID frame two right-angle side as right-angle side, and its most of area and protractor 2 share, and hypotenuse is crossing with the outer camber line of protractor 2, and is in same plane.

Between described protractor 2 inner arc and main scale 1 Triangle ID frame right-angle side, and the space that the hypotenuse of 45 degree of chis 3 and protractor 2 arc-shaped side, each limit of main scale 1 Triangle ID frame surround is engraved structure, to reduce unnecessary material consumption as much as possible, saving resource to greatest extent.

This structure can be used for the common drawing tool of student, adopts the material such as plastics or stainless steel to make, also can be used as teacher's teaching appliance, usually adopt the material such as plastics, timber to make.

During use, the first, draw straightway by limit any in three limits of main scale 1, carried out the linear measure longimetry of straightway by two right-angle sides, draw 30 ° of angles, 60 ° of angles, 90 ° of angles by three angles of main scale 1; The second, draw 30 ° of angles, 60 ° of angles, 90 ° of angles by Triangle ID frame 4; 3rd, draw 45° angle by 45 degree of chis 3; 4th, directly measure the angle angle of 0 ~ 90 ° by protractor 2, and the angle at any obtuse angle can be measured at the auxiliary lower of boost line or change measuring position.
