Abstract
The utility model relates to an ellipse drawing gauge for drawing standard ellipes. The utility model is composed of a guide disc, guide slots which are vertically arranged on the guide disc and are overlapped and communicated top and bottom at the cross position, a sliding guide rod which is glidingly arranged in the guide slot and a drawing rule which is connected through a guide shaft arranged on the guide rod. The ellipse drawing gauge has the advantages of simple structure and easy use. The utility model can be used for drawing the standard ellipses with various standards.
Description
The utility model relates to a kind of drawing tool that is used for the drawing standard elliptical orbit.
It is just round more complex to draw oval drafting.It is convenient that people do one's utmost to attempt with a kind of drawing instrument, directly draw various required accurate ellipse figures, wherein have according to the basic principle of ellipse " if two fixed points and a moving point is constant apart from sum; track that then should moving point is an ellipse; " and the flexible rope ellipsograph of fixed length of design, also just like " the standard ellipse rule " of Chinese patent CN922153551.5 design, it is to be made of the pen clip that has on cross recessed cross guide plate and adjustable rule dish and the adjustable rule dish, and the top of cross guide plate is provided with four pilot pins and is used for fixing axial location, rotates the adjustable rule dish by its tip of the brushstyle of a writing or painting ellipse figure that draws.The structure of this ellipsograph is comparatively complicated, and the oval specification of drawing is subjected to the restriction of the determined model figure of pilot pin.Also have, present various ellipsographs all do not have the function of the oval camber line of drawing a certain angle Fan Tunei, and therefore, existing ellipsograph is still not very perfect.
Goal of the invention of the present utility model is to provide a kind of oval drawing instrument of drawing, and especially provides a kind of specification simple in structure, easy to use, oval unrestricted oval drawing gauge.
Realize the oval drawing gauge of the present utility model purpose, the drawing rule that is foundation " in collinear three fixed points; two wherein adjacent fixed points are respectively at X; move on the parameter of Building Y; then the running orbit of other end fixed point is oval " designs, the primary structure characteristics of this ellipse drawing gauge are that it comprises godet, the vertical setting and the overlapping guide groove that communicates of infall on the godet, the sliding guide and the drawing rule that are slidingly arranged in the guide groove constitute, drawing rule is to be connected with sliding guide by the guide shaft on the sliding guide, mobile drawing rule makes sliding guide slide along guide groove is directed, and then the running orbit of drawing rule end points then is an ellipse.Be carved with the angle groove on the godet circumference, then can draw the oval camber line of the different angles Fan Tunei in 360 ° as required.
The oval specification that oval drawing gauge of the present utility model has a drafting is not subjected to the characteristics of godet restriction, this is to lead because guide groove is the slip of sliding guide, guide shaft on the guide rod is that the fixed point shift position of drawing rule is can exceed godet on the guide groove direction, on drawing rule, adjust two guide shafts and the distance of drawing and holding during drawing, after promptly determining the length numerical value of transverse and minor axis, the drawing end of mobile drawing rule, lead by two sliding guides in the guide groove, its formed track of end of drawing is an ellipse, it is simple in structure, and it is very convenient to draw.In this oval drawing gauge, can in required angle, draw corresponding oval camber line, remedy the deficiency that original ellipsograph can only draw whole elliptical orbits at the circumference upper angle scale of godet.
Under will describe technology contents of the present utility model in detail in conjunction with the concrete structure of implementing.
Fig. 1 is the perspective view of this oval drawing gauge
Fig. 2 is the godet master TV structure figure of this oval drawing gauge
Fig. 3 is the A-A structure cutaway view of Fig. 2
Fig. 4 is that one of drawing rule is implemented structural representation.
As shown in the figure, the oval drawing gauge of the utility model design is made up of godet 2, sliding guide 3,4 and drawing rule 1, sliding guide 3,4 is slidingly arranged in respectively in the vertical and overlapping guide groove that communicates 8,5 of infall on the godet 2, respectively be fixed with a guide shaft 7,6 on the sliding guide 3,4, drawing rule 1 is connected with sliding guide by guide shaft 7,6.Drawing rule 1 is provided with chute 9 or the hole, chi position 10 that is used to adjust guide shaft 6,7 positions, adjust guide shaft 6,7 and the distance of the end 11 of drawing, the numerical value of promptly determining ellipse short shaft and major axis is also fixing, rotate drawing rule 1 and drive sliding guide 3,4 staggered slip in guide groove 5,8, the end 11 of drawing can be drawn a standard ellipse.The drawing end 11 of drawing rule 1 can be the hole or other various devices that are used for fixing drawing pen are set, position of plug-in mounting drawing pen, as fixing pen clip etc.
In the present embodiment, be carved with angle scale on the circumference of godet 2, the oval camber line in a certain corner that can draw.Position at the guide groove straight line of godet 2 bottom surfaces is provided with two pilot pins, is used for fixing the drawing position of this oval drawing gauge.
