Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is described in further detail by detailed description of the invention.

First, refering to shown in Fig. 1, this utility model one novel bow compass angle square is mainly by a scale Chi body 11 and angle gage structure 12 and the compasses structure group being integrated on this rule body 11 Become.

Wherein, rule body 11 is by one first drawing square 111 and one second drawing square 112 compositions, the Article 1 right-angle side of this first drawing square 111 and this second drawing square 112 Article 1 right-angle side mutually splice, the Article 2 right-angle side of this first right angled triangle 111 with this The Article 2 right-angle side of two right angled triangles 112 is located along the same line.At the first right angled triangle 111 With on the inclined-plane of the second right angled triangle 112, the Article 2 right-angle side of the first right angled triangle 111 and Length scale can be equipped with on the Article 2 right-angle side of the second right angled triangle 112, utilize rule originally Body 11 realizes line and the function of tolerance.

In the present embodiment, the first right angled triangle 111 and the second right angled triangle 112 use conventional Set square；First drawing square 111 is isosceles drawing square, has two 45 ° of drift angles, Second right angled triangle 112 has 60 ° of angles of 30 ° of drift angles and a top；First drawing square The length of the Article 1 right-angle side of 111 is less than the length of the Article 1 right-angle side of the second right angled triangle 112 Degree so that 30 ° of drift angles of the second right angled triangle 112 protrude from the first right angled triangle 111, from And make rule body 11 have 30 ° of drift angles, 45 ° of drift angles, 60 ° of drift angles With 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, this angle gage structure 12 There is base, arc-shaped edges, the center of circle and the protractor scale arranged along arc-shaped edges, utilize angle gage structure 12 functions realizing protractor.

Compasses structure is retouched line compass leg 131 by one and a needle of compasses 132 forms, and retouches line compass leg 131 Being rotationally connected with on rule body 11 by a pivot 14, retouching line compass leg 131 can be flexible circle Rule lower limb, and retouch line compass leg 131 be provided with for line drawing pen core 133, needle of compasses 132 It is located at the outer of rule body 11, it is possible to achieve with the needle point of needle of compasses 132 as the center of circle, with circle Distance between needle point and the end retouching line compass leg 131 of compass needle foot 132 is that radius is drawn circle or draws circle Arc, thus realize calipers function.

Below the center of circle of angle gage structure 12, be provided with a pivotal mounting hole, the first end of pivot 14 with The line compass leg 131 of retouching of compasses structure connects, and the second end of pivot 14 plugs and rotate in pivotal mounting In hole, thus coordinating by pivot 14 and pivotal mounting hole, make compasses structure retouches line compass leg Below 131 centers of circle being rotationally connected with angle gage structure 12.

Coordinating shown in Fig. 2, pivotal mounting hole is led along the base of angle gage structure 12 to both sides extension formation To groove 15, the second end of pivot 14 is slidedly arranged in gathering sill 15, retouches line compass leg 131 edge to drive Gathering sill 15 moves, to be moved put in place after, the nut tightening pivot 14 end positions.Scale The outer of chi body 11 is provided with the needle tray 16 being located along the same line with gathering sill 15, compasses structure Needle of compasses 132 is inserted in this needle tray 16.The protractor scale utilizing angle gage structure 12 is permissible Control needle of compasses 132 and the angle retouched between line compass leg 131, then control drawn by compasses structure Circle or the radius of circular arc；Or can also arrange with pivotal mounting hole as the center of circle on rule body 11 Angle index line 17, control needle of compasses 132 and the angle number of degrees retouched between line compass leg 131. This utility model, by pivotal mounting hole is set to gathering sill 15, can make pivot 14 at gathering sill Move in 15, then drive and retouch line compass leg 131 and translate, when drawing the less circle of radius or circular arc, Line compass leg 131 can be retouched by translation and facilitate minor radius circle or the drafting of circular arc.

Coordinate again shown in Fig. 3, for the ease of drawing out the less circle of radius or circular arc, at gathering sill 15 Two ends formed vector hornwork structure 12 1 lateral buckling arc tilt 151, be more beneficial for draw compasses Stitch 132 situation minimum with the angle retouching line compass leg 131 to circle or circular arc.

Above in association with drawings and Examples, this utility model is described in detail, common in this area This utility model can be made many variations example by technical staff according to the above description.Thus, in embodiment Some details should not constitute restriction of the present utility model, this utility model will be with claims The scope that book defines is as protection domain of the present utility model.
