Description
Technical field
The utility model is related to a kind of drawing rule, in particular for student's multifunctional drawing ruler of plan Drawing.
Background technology
Existing multifunctional drawing ruler draws circle and two ways is usually taken：One is the hole by designing determination on chi body,
Circle is drawn by radius of pitch of holes, but it can only draw a small number of circles for determining diameter, it is impossible to any circle of certain size scope is drawn, together
When, because chi body plane is contacted with drawing, when drawing circle rotary motion, chi body rubs with drawing bump contact, tends to do
Dirty drawing；Two be to set movable sliding block on chi body, and the radius for moving regulation circle by sliding block draws certain size scope
Circle, this mode is due to that will set mobile sliding block, so not being single plane chi body, structure is relative complex, drawing rule
It is easily damaged.
Published multifunctional drawing ruler patent shows, its shape facility, using function is primarily adapted for use in students in middle and primary schools, lacks
It is applied to the drawing function in terms of Graphing of Engineering less.
Utility model content

Above-mentioned multifunctional drawing ruler is on chi body using shaping profile, shaping hollow out, groove scale, positioning aperture, circle
The mode of boss, can draw scale straight line, measure and draw angle line, draw any circle of a diameter of 3-175mm scopes, draw
Go out some circles of a diameter of 175-205mm scopes；Simplicity draws a diameter of 6mm, 10mm, 14mm, 28mm, 42mm, 56mm circle
It is positive to wait survey ellipse, specification to be the bolt head of M4, M5, M6, M8, M10, M12, M16 bolt and the regular hexagon of nut；Directly draw
Arrow, surface roughness symbols, form and position tolerance fiducial mark, Marking of Shape and Position Tolerance housing in Graphing of Engineering；Chi body and mapping
Chi body can be reduced during the relative rotary motion of face and contacts friction area with drawing.
Above-mentioned multifunctional drawing ruler can be with complete by chi body length direction straight line and size groove, chi body one end protractor
Into functions such as picture straight line, parallel lines, measuring angle and picture angle lines
Above-mentioned multifunctional drawing ruler directly draws a diameter of 3-6mm circle by hollow out circle on chi body, to be set by mathematical law
Fixed chi body length direction one is ranked an aperture and perpendicular left and right two is ranked in an aperture, and some aperture is the center of circle, is arrived
The distance of another positioning aperture is radius, can draw a diameter of 7-175mm any circle, can also draw a diameter of 175-
Some circles of 205mm scopes.
Above-mentioned multifunctional drawing ruler just etc. surveys ellipse by what hollow out ellipse on chi body directly drew a diameter of 6mm, 10mm circle
Circle, is ranked an aperture and small with its vertical another position that is ranked in middle part with the chi body length direction one set by mathematical law respectively
The aperture of some in hole is the center of circle, and the small distance between borehole of some in an aperture is ranked for radius (major axis or short axle) to oblique one,
Easy can draw a diameter of 14mm, 28mm, 42mm, 56mm circle just etc. surveys oval.
Above-mentioned multifunctional drawing ruler by hollow out regular hexagon on chi body directly draw specification be M4, M5 bolt bolt head
And the regular hexagon of nut, with the chi body one side stepped tooth set by mathematical law, can simplicity draw in Graphing of Engineering commonly use
Specification for M6, M8, M10, M12, M16 bolt bolt head and nut regular hexagon.
Above-mentioned multifunctional drawing ruler can directly draw the arrow commonly used in Graphing of Engineering by the hollow out shape on chi body
Head, surface roughness symbols, form and position tolerance fiducial mark, Marking of Shape and Position Tolerance outline pattern.
Above-mentioned multifunctional drawing ruler at the several circular holes of chi body one side by increasing round boss, chi body when drawing circle or circular arc
Turn-over is used, and is contacted with chi body round boss with drawing, and picture can be avoided to justify or chi body and drawing big face during the rotation of dial scale body
Product contact rubs and makes drawing dirty.
Above-mentioned multifunctional drawing ruler is due to that with ruler and picture circle function, can also use Graphing of Engineering drafting principle and mapping
Method, draws the figures such as various various sizes of ellipses, regular hexagon.
A kind of multifunctional drawing ruler of the utility model includes what present college's Students ' Learning Graphing of Engineering was commonly used substantially
A set of drawing instrument function, and come together on a flat Plexiglass chi body, both it was convenient for carrying, used, economy is substantially reduced again
