Abstract
The utility model relates to a high-efficiency drawing device used for measuring and fast drawing figures, and the painting of auxiliary examination card with the special purpose. The utility model is characterized in that an angle square, and a 60 DEG triangular rule and a 30 DEG triangular rule are combined to a whole. A semicircle hole whose upper part is cut out leaves out an equicrural triangular rule which can be connected with the angle square to form a whole. The side of the semicircle is 0-180 DEG scale marks to form a protractor. The upper part of the angle square is provided with a rotary bolt, and the lower part is provided with a circle center needle which can extend out and fix. The circle center needle and a vernier which can move along a sliding rail, with a pen head can draw the circle in man-made and fixing distance mode. The upper part is also provided with a painting window of a subsidiary examination card with the special purpose, and holes of hyperbola, ellipse, and parabola. Therefore, the related figures can be fast drawn with convenience, and the auxiliary examination card with special purpose can be painted.
Description
The utility model is to be used for measuring with quick graphing reaching a kind of efficient plotter that auxiliary examination personality card is smeared.
Common drawing instrument commonly used now is set square, protractor, the compasses of function singleness.On the market,, get two hands and draw circle, use inconvenient though a kind of QuickDraw instrument is arranged.
The purpose of this utility model is that a kind of angle square, set square, protractor, compasses, examination personality card template will be provided is the efficient plotter of one, is used for tolerance and graphing and auxiliary examination personality card are smeared fast.
The utility model is achieved in that angle square and 60 °, 30 ° of set square one, in the above, in the semicircle hole that cuts out, the surplus next one is the isoceles triangle chi of one with angle square, angle square and isoceles triangle chi are carved with millimeter, centimetre length unit, it on the semicircle limit 0-180 ° graduation mark, form protractor, on angle square, on the rotation bolt is arranged, the fixing center of circle pin of extended energy is arranged down, can with can be on the vernier rail movable vernier, artificial set a distance is drawn circle, the top also has auxiliary examination personality card to smear window, and it is oval, parabola, the hyperbola hole is used for drawing relevant figure fast and accurately smearing the examination personality card.
Below in conjunction with accompanying drawing utility model is further described in detail.
Fig. 1 is the utility model basic structure schematic diagram.
Fig. 2 is the utility model vernier schematic diagram.
With reference to Fig. 1, circular rotation bolt (1) is an one with angle square (15), angle square (15) with 60 °, 30 ° set square (3) is an one, the surplus next one is the isoceles triangle chi (6) of one with angle square (15) in the semicircle hole (4) that cuts out, be 0-180 ° of graduation mark (5) on the limit, semicircle hole (4), thereby formation protractor, isoceles triangle chi (6) and angle square (15) are carved with centimetre, mm length unit (9), vernier rail (7) packs on the grooving (23), center of circle pin (13) part injects in the slide cores (14) of cavity (10) the inside of swelling, go up fixing at slip ditch (11) by gim peg (12), (16) 24 of examination personality card windows hollow out, oval hole, hyperbola hole (2) (8), parabola hole (17) hollow out.
With reference to Fig. 2, nib (22) part injects in the slide core (21) of cavity (18) the inside of swelling, and is gone up at groove (19) by housing screw (20) and fixes, and drives written (22) movable grooving (23) and gulps down on vernier rail (7).
During use, measure and graphing the size of 0-180 ° graduation mark (5) measured angular and the number of degrees at the required angle of graphing on the limit, semicircle hole (4) with the particularity of angle square (15) or 60 °, 30 ° set squares (3) or isoceles triangle chi (6).
With isoceles triangle chi (6) and the formed angle of angle square (2) one, can do short vertical line, little quadrangle, use 0-180 ° of graduation mark (5) again and can make little triangle, fan-shaped, polygon and polyhedron, allow center of circle pin (13) stretch out, gim peg (12) is fixing, moving cursor drives the pen bucket (22) of stretching out then, fixing with housing screw (20), form set a distance, rotate rotation bolt (1) and draw circle, use the parabola hole (17) that is hollowed out, hyperbola hole (2), oval hole (8) can be drawn the parabola of signal respectively, hyperbola, ellipse is smeared with the auxiliary examination of examination personality card window (16) personality card.
Claims (2)
1. efficient plotter, by rotation bolt (1), angle square (15), set square (3), semicircle hole (4), 0-180 ° of graduation mark (5), isoceles triangle chi (6), vernier rail (7), center of circle pin (13), nib (22) is formed, it is characterized in that: rotation bolt (1) is one with angle square (15), the surplus next one is the isoceles triangle chi (6) of one with angle square (15) in the semicircle hole (4) that cuts out, be 0-180 ° of graduation mark (5) on the limit, semicircle hole (4), center of circle pin (13) partly injects in the slide cores (14) of cavity (10) the inside of swelling, go up fixing at slip ditch (11) by gim peg (12), nib (22) partly injects in the slide core (21) of cavity (18) the inside of swelling, upward fixing at groove (19) by housing screw (20), movable grooving (23) gulps down on vernier rail (7) to drive nib (22).
