Three angles of the bottom surface of the drawing set square are all provided with salient points. The utility model is provided with parallel edges which are arranged on the right-angle sides of the drawing set square. The utility model is also provided with a handle, and the drawing set square is provided with a handle groove matched with the handle so as to be convenient and practical. The right-angle sides are both provided with protractor calibrations. The utility model has reasonable structural design, draws the regular polygon easily, does not pollute the picture easily in drawing, has multiple functions, and is convenient and practical.
Description
Technical field:
The utility model relates to a kind of multi-functional drawing set square.
Background technology:
General set square can only be used for drawing triangle or measuring angle, and function ratio is more single, is difficult to draw regular polygon, is difficult to draw parallel edges, takes inconvenience, and angle is measured inconvenience.Make the edge of inkiness set square when existing drawing set square is drawn usually easily, thus when mobile set square dirty bad picture.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of convenient multi-functional and difficult drawing set square that influences drawing quality of drawing regular polygon is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this drawing set square, comprise two right-angle sides, a hypotenuse, it is characterized in that being provided with regular polygon length of side scale, described regular polygon length of side scale comprises that length of side ruler origin, the limit of regular polygon count scale, circumradius mark, when the regular polygon circumradius was got the value that the circumradius mark indicated, the distance that scale is counted on length of side ruler origin to limit was described limit and counts the length of side that scale indicates the regular polygon of limit number.
Circumradius described in the utility model is labeled as 5CM, and the limit is counted scale and comprised 100,36,30,20,15,10,9,8,7,6,5,4 and 3.
Drawing set square described in the utility model is 45 ° of right angle triangles.
The utility model right-angle side is provided with parallel edges.
Parallel edges described in the utility model all has three on two right-angle sides, respectively apart from 3,5,10 millimeters of the right-angle sides at place.
The utility model also is provided with handle, and drawing set square is provided with the handle groove that cooperates with handle.
Be provided with salient point on three angles of drawing set square described in the utility model bottom surface.
Salient point described in the utility model is arranged on the limit on three limits of drawing set square.
The protractor scale all is set, than the more accurate convenience of traditional triangle chi intensive amount hornwork on the utility model right-angle side.
The utility model makes to be not easy the drawing of making dirty during drawing by the convenient regular polygon of drawing that function is many, and is convenient and practical by the structural design of drawing set square.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the schematic diagram of the utility model embodiment handle and handle groove.
Fig. 4 is the schematic diagram of the utility model embodiment regular polygon length of side scale usage.
The specific embodiment:
Referring to Fig. 1～4, the utility model drawing set square comprises two right-angle sides, hypotenuse and length and angle index, the utility model is provided with regular polygon length of side scale D, regular polygon length of side scale D is arranged between the semi arch of two sign angles, and regular polygon length of side scale D comprises the length of side ruler origin D of regular polygon
1, the limit counts scale D
2, circumradius mark D
3, when the regular polygon circumradius is got circumradius mark D
3During the value that is indicated (special case is 5 centimetres), length of side ruler origin D
1Count scale D to the limit
2Distance be described limit and count scale D
2The length of side of the regular polygon of limit number that indicates.
The circumradius mark D of the utility model embodiment
3Be 5CM, scale D is counted on the limit
2Comprise 100,36,30,20,15,10,9,8,7,6,5,4 and 3, expression is when the circumradius of regular polygon is 5 centimetres respectively, and the length of side that the limit number is respectively 100,36,30,20,15,10,9,8,7,6,5,4 and 3 regular polygon is length of side ruler origin D
1Count scale D to the limit
2Distance.
The usage of regular polygon length of side scale D is as follows:
1. make the circle that a radius is 5CM;
2 usefulness compasses are measured length of side ruler origin D
1(among Fig. 1 above the A a bit) counts scale D for basic point arrives corresponding edge
2Distance (promptly measure length of side ruler origin D
1Count scale D to selected limit
2Distance, for example to draw just heptagonal words, measure length of side ruler origin D
1Count scale D to the limit
2Be 7 distance, referring to Fig. 4);
3. with compasses five equilibrium arc on circumference;
4. gained circular arc joining is the regular polygon summit of asking;
5. the character with string connects each joining in regular turn with straight line, finishes mapping.
Be provided with salient point F on three angles of the utility model drawing set square bottom surface, described salient point F is used for supporting drawing set square, the ink that the drawing set square edge is stained with make drawing set square bottom surface and drawing object only keep some points (or little disk) to contact, so that can not pollute drawing.As a kind of special case, described drawing set square is 45 ° of right angle triangles.
