Abstract
The utility model is a ruler for drawing straight line, wavy line, geometric figure, measuring length and angle. Consists of a set square, a small ruler plate and a contact pin. The triangular ruler is internally provided with a protractor, a regular polygon and a plurality of small round holes for fast drawing, and is provided with corresponding length scales and marks, the small ruler plate is provided with a straight line edge, a wave-shaped edge, a plurality of small round holes, and the corresponding length scales and marks, in order to solve the problem that pictures are polluted by drawing lines or figures with steel strokes, a plurality of hemispherical convex body 'feet' are respectively arranged on the back surfaces of the triangular ruler and the small ruler plate. Has more than ten functions and is suitable for teachers, students, design, secretary, accountants and other personnel.
Description
The utility model belongs to the stationery category scope.
Though it is multiple that existing set square has, all function is few, and only is suitable for the pencil line, still finds no so many function so far and can use the not set square of stained picture of pen line.
The purpose of this utility model is that price is low, does not select pen for society provides a kind of function many, material saving, the easily set square of making.
The utility model is by three chis (1), little chi plate (2), and contact pin (3) (available pencil replacement) is formed.Three limits of set square have centimetre, millimeter scale of some respectively, use arabic numeral annotation corresponding digital 1,2,3 respectively at each centimeter scale place ... in set square, be provided with a protractor 1, scale mark and angle annotation 2 that the expression angle is arranged on the semi arch of protractor, since 0 every 10 up to 180 degree places, with arabic numeral annotation corresponding digital 0,10,20 The straight line of protractor (diameter) is established a small sircle hole, as the center of circle of protractor, at circular arc and extraneous intersection two hollow arcs 6,7 is set, and is convenient to angulation; It is 1 millimeter small sircle hole that appropriate location in protractor is provided with 20 diameters, be used for inserting contact pin or draw point, 20 small sircle holes are formed the positive 8 limit shapes 4 of positive 5 limit shapes 3,, positive 6 limit shapes 5 respectively, each small sircle hole is respectively the central point or the summit of regular polygon, links to each other with line segment in the middle of two adjacent small sircle holes; Diverse location in set square is respectively arranged with small sircle hole and 1 short groove of 14 and 51 millimeter of 12, one empty oval 13, one little empty circle of an empty rectangle; Small sircle hole, central point small sircle hole place at the upper and lower corner of the short groove at oval 13 edges and positive 8 limit shapes 4, annotation has arabic numeral 2,3,4,5 respectively, represent respectively this groove or o'clock to the vertical range of two straight lines be 2 centimetres, 3 centimetres, 4 centimetres, 5 centimetres, select when being made for square to use; Article two, the central spot annotation of small sircle hole between right-angle side and the protractor 8,9 and positive 6 limit shapes has 30, and the right-angle triangle that is used for one of them angle of picture and is 30 ° is used.Little chi plate is a rectangle, and two long limits are respectively a straight line and a waveform limit 20, and straight line has centimetre, millimeter scale, and at each centimeter scale line place respectively annotation arabic numeral 1,2,3 are arranged ...Straight line every 5 millimeters places in the middle of the little chi plate is provided with small sircle hole 21, and each small sircle hole all can be drawn circle as the center of circle or slotting nib by contact pin.Appropriate location at set square and little chi plate reverse side is provided with several hemispherical convex bodys respectively, and sphere is outside, and plane and chi plate combine together, as " pin ", in case inkiness picture during with line such as pen.Contact pin is made of cube handle 25 and metal needle 26, assigns a metal needle in the central authorities of cube handle one end.
Structure of the present utility model is as shown in the figure:
(1) set square; (2) little chi plate; (3) contact pin.
1, protractor, 2, the angle annotation, 3, positive 5 limit shapes, 4, positive 8 limit shapes, 5, positive 6 limit shapes, 6,7 hollow arcs, 8,9 angle annotations (30 °) represent that line and the folded angle of opposite side that put therewith at this some distance angle farthest are 30 °, 10,11 length scale and annotations, 12, little empty rectangle, 13, little empty oval, 14, little empty circle, 15, vertical range annotation (3 among the figure with two right-angle sides, 4,5 is same with " 2 ", represents that respectively small sircle hole (short groove) to the vertical range of two right-angle sides is 2 centimetres, 3 centimetres, 4 centimetres, 5 centimetres), 16,17,18,19,22,23, the 24th, the convex body at the chi back side " pin " is in the development in front, 20, the waveform limit, 21, draw the small sircle hole of circle usefulness, 25, handle, 26, metal needle, 6,7,12,13,14 each figure are hollow.
Function of the present utility model and using method are as follows:
1, amount straight length or draw straight line by length;
2, measuring angle or draw the angle by angle;
3, draw regular polygon, draw circle in connect the circumscribed regular polygon of regular polygon, circle.The regular polygon that will draw is aimed at the appropriate location of paper, in the small sircle hole on its each summit, with putting in order, connect adjacent each point thereafter.When figure need dwindle or amplify (need add with little chi plate and contact pin), only need that the Len req place puts in order on the line on central point and each summit or extended line, connect adjacent each point again.Draw circle in when connecing regular polygon or circumscribed regular polygon, as long as after carrying out regular polygon, be the center of circle with the central point of regular polygon, be that the radius picture is justified with central point to one of them summit or with the vertical range on central point to a limit.
4, draw square, along two straight lines on request length draw two mutually perpendicular vertical lines, put in order in annotation has the small sircle hole of requirement length, respectively the end points of this point and two mutually perpendicular straight lines is coupled together, the length of side of can drawing fast is 2~5 centimetres a square.
5, be decorated with the right-angle triangle at 30 degree angles.Draw and two mutually perpendicular straight lines of one long 6 centimetre isometric respectively along two right-angle sides with right-angle side, annotation has in the small sircle hole 8 or 9 of " 30 ° " and puts in order outside protractor, (positive 6 limit shapes in " 30 ° " be the little right-angle triangle of picture), again this point and two vertical line end points are coupled together.
6, draw small rectangle, ellipse, roundlet with 12,13,14.
7, radius is drawn circle on request.With any small sircle hole 21 in the little chi plate is the center of circle (insert with contact pin fixing), be radius (inserting nib in corresponding small sircle hole) to require length, is rotating to draw 360 and spend.Draw the concentric circles of several different radiis that just can draw simultaneously if in several small sircle holes of different distance, insert several nibs.
8, draw parallelogram.With two limits at any acute angle place of triangle on request length draw two crossing straight lines, in the small sircle hole of respective length, put in order, the end points of this point and two straight lines is coupled together.
9, draw parallel lines.A straight line is drawn on long limit along set square, put in order in two small sircle holes on the both sides, summit of positive 8 limit shapes, or respectively put in order at the digital annotation place that two straight lines equate, connects 2 points and (can prolong or shorten).
10, draw wave with 20.
The utility model has the advantages that to integrate two kinds of set squares, protractor, compasses, maximize favourable factors and minimize unfavourable ones, function is many, and price is low, does not select pen, and the material saving easily makes, and can be made into different size, is fit to the triangle ruler that various people use.
