Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the present invention is further detailed explanation.
First, consult shown in Fig. 1, a kind of rule with compasses and protractor of the present invention is primarily of a rule body 11 and the angle gage structure 12 be integrated on this rule body 11 and compasses structure composition.
Wherein, rule body 11 is made up of one first drawing square 111 and one second drawing square 112, the Article 1 right-angle side of this first drawing square 111 and the Article 1 right-angle side of this second drawing square 112 splice mutually, and the Article 2 right-angle side of this first right angled triangle 111 and the Article 2 right-angle side of this second right angled triangle 112 are located along the same line.Can length scale be equipped with on the inclined-plane of the first right angled triangle 111 and the second right angled triangle 112, on the Article 2 right-angle side of the first right angled triangle 111 and the Article 2 right-angle side of the second right angled triangle 112, utilize rule body 11 to realize the function of line and tolerance.
In the present embodiment, the first right angled triangle 111 and the second right angled triangle 112 adopt conventional set square; First drawing square 111 is isosceles drawing square, has two 45 ° of drift angles, and the second right angled triangle 112 has 30 ° of drift angles and a top 60 ° of angles; The length of the Article 1 right-angle side of the first drawing square 111 is less than the length of the Article 1 right-angle side of the second right angled triangle 112,30 ° of drift angles of the second right angled triangle 112 are made to protrude from the first right angled triangle 111, thus make rule body 11 have 30 ° of drift angles, 45 ° of drift angles, 60 ° of drift angles and 135 ° of re-entrant angles, enrich the angle of rule body 11.
Angle gage structure 12 hollow out is formed at the middle part of rule body 11, the protractor scale that this angle gage structure 12 has base, arc-shaped edges, the center of circle and arranges along arc-shaped edges, utilizes angle gage structure 12 to realize the function of protractor.
Compasses structure retouches line compass leg 131 by one and a needle of compasses 132 forms, retouching line compass leg 131 is rotationally connected with on rule body 11 by a pivot 14, retouch line compass leg 131 and can be flexible compass leg, and retouch line compass leg 131 and be provided with drawing pen core 133 for ruling, needle of compasses 132 is located at the outer of rule body 11, can realize being the center of circle with the needle point of needle of compasses 132, drawing round with the distance between the needle point of needle of compasses 132 and the end of retouching line compass leg 131 for radius or draw circular arc, thus realize calipers function.
A pivotal mounting hole is provided with below the center of circle of angle gage structure 12, the first end of pivot 14 is connected with the line compass leg 131 of retouching of compasses structure, second end of pivot 14 plugs and rotates in pivotal mounting hole, thus coordinating by pivot 14 and pivotal mounting hole, the line compass leg 131 of retouching of compasses structure is rotationally connected with below the center of circle of angle gage structure 12.
Coordinate shown in Fig. 2, pivotal mounting hole extends to form gathering sill 15 along the base of angle gage structure 12 to both sides, and the second end of pivot 14 is slidedly arranged in gathering sill 15, retouches line compass leg 131 move along gathering sill 15 to drive, to be moved put in place after, the nut tightening pivot 14 end positions.The outer of rule body 11 is provided with the needle tray 16 be located along the same line with gathering sill 15, and the needle of compasses 132 of compasses structure is inserted in this needle tray 16.Utilize the angle that the protractor scale of angle gage structure 12 can control needle of compasses 132 and retouch between line compass leg 131, then control the radius of the drawn circle of compasses structure or circular arc; Or the angle index line 17 that can also to arrange with pivotal mounting hole on rule body 11 be the center of circle, the angle number of degrees controlling needle of compasses 132 and retouch between line compass leg 131.The present invention is by being set to gathering sill 15 by pivotal mounting hole, pivot 14 can be made mobile in gathering sill 15, then driving and retouch line compass leg 131 translation, when drawing the less circle of radius or circular arc, can retouch by translation the drafting that line compass leg 131 facilitates minor radius circle or circular arc.
Coordinate again shown in Fig. 3, for the ease of drawing out the less circle of radius or circular arc, the arc forming vectorial hornwork structure 12 1 lateral buckling at the two ends of gathering sill 15 tilts 151, be more conducive to drawing needle of compasses 132 and the minimum situation of angle of retouching line compass leg 131 to circle or circular arc.
Below by reference to the accompanying drawings and embodiment to invention has been detailed description, those skilled in the art can make many variations example to the present invention according to the above description.Thus, some details in embodiment should not form limitation of the invention, the present invention by the scope that defines using appended claims as protection scope of the present invention.
