Abstract
Disclosed is universal compasses for drawing plane graphs, which is a combined type drawing instrument assembled with a slide bar, a slide block, a rotation shaft, a supporting foot and a line drawing pen, etc. The utility model adopts different connection modew of the slide bar to realize different line drawing functions. The drawing instrument can not only draw circles, ellipses, cardioid and ova circles, but also draw circles without indefinite centers of the circles and big circles and circular arcs of especially big radius which ordinary compasses can not draw, etc. The utility model has the advantages of multiple function, high speed, homogeneous line and convenient operation.
Description
The utility model relates to a kind of instrument of drawing the plane curve figure.
Existing drawing instrument and instrument all exist function singleness, the narrow defective of the scope of application as compasses, ellipsograph, curve ruler and various template.Can only draw radius less than the circle of compasses bipod span as common compasses, and the fixedly place in the center of circle will be arranged.Common ellipsograph is because its bearing is positioned at oval centre, thereby can only draw greater than the ellipse of ellipsograph bearing the loaded down with trivial details graphing method that also need adopt trace-point method and curve ruler to combine when needing the circular arc of the especially big radius of picture.
It is many that the purpose of this utility model is to design a kind of drawing function, the universal compass that the scope of application is wide.It not only can draw circle, and can draw ellipse, cardioid, ovum circle, can also need not determine the center of circle draw justify and draw common compasses the great circle that can not draw and the circular arc of especially big radius etc.
The utility model is achieved in that it forms a kind of dismountable combined type instrument by connecting rod, detail pen and securing member.Connecting rod is assembled by four slide bars, can different connected modes be connected between each slide bar and between detail pen and the slide bar, to realize different setting-out functions.
Concrete structure of the present utility model is provided by following example and accompanying drawing.
Fig. 1 is the structural representation of universal compass.
Slide bar (1), (2), (3), (4) are that both sides have chute, and there is the rod member of through-hole groove the centre.Two slide blocks (5) are enclosed within on the slide bar, cooperate with the chute of slide bar both sides, can be free to slide ， And along chute and be connected with another slide bar with nut (11) by rotating shaft (6).Two support foots (8) and detail pen (7) are fixed on the slide bar with screw (9).Other has two pilot pins (12) that supply the picture prelocalization to use.All can be connected between detail pen (7) and the slide bar and between each slide bar by screw (9) or screw (10) and nut (11).Use different connected modes just can realize different setting-out functions.
Can successfully assemble for making between each slide bar, at the breach that there is step at an end and the middle part of slide bar (1), there is a circular hole at the center of breach; There is a circular hole at the middle part of slide bar (2), and respectively there is " L " shape groove perpendicular to the slide bar length direction both sides in hole.Its effect be when with screw (10) and nut (11) slide bar (1) and slide bar (2) when connecting to orthogonal member, the slide block on the slide bar (1) can successfully slide into the other end from an end.One end of slide bar (3) has the step breach, and there is a circular hole at the breach center, and this place's rod end is semicircle shape.One end and the middle part of slide bar (4) all have the step breach, and there is a circular hole at the breach center, and the rod end indentation, there is semicircle shape.Therefore, can connect to "T"-shaped member to slide bar (4) and slide bar (1) or slide bar (3) with screw (9) and nut (11); It is 90 °-180 ° member that slide bar (4) and slide bar (3) can connect to angle; Also can connect to stock between the slide bar.Have a hole that is used to assemble rotating shaft (6) on the slide block (5).One end of rotating shaft (6) has helicitic texture, can link together slide bar and slide block by nut (11).Having one on the axis of rotating shaft (6) can be for the aperture that inserts pilot pin (12).The written structure of the similar common compasses of detail pen (7), an end can be loaded onto the pen core of pencil-lead, scriber or other type, and the other end is a female thread structure, is assemblied on the slide bar with screw (9).Support foot (8) one ends are pointed, and the other end has helicitic texture, can connect to one with slide bar with nut (11), fix and support universal compass and use.On the axis of screw (10) circular hole is arranged, insert pilot pin (12) in the time of can supplying the location and use.For conveniently taking measurements, the one side of the two sides of slide bar (2) and slide bar (3) has rule, and the head of screw end face of screw (9), (10) has a graduation mark and rule to be used.
Connected mode when structure shown in Figure 1 is universal compass picture cardioid.When the axis spacing of two rotating shafts (6) from equal detail pen (7) to the intersection point of orthogonal slide bar (1), (2) apart from the time, the figure that detail pen (7) is drawn is a cardioid.
As needs picture ellipse, available screw (10) and nut (11) slide bar (1), (2) are vertical fuses with dividing equally, be connected two ends with screw (9) with nut (11) at an end of slide bar (1) slide bar of support foot (8) (4) be housed.Slide block (5) packs into respectively on slide bar (1), (2) after loading onto rotating shaft (6), with nut (11) slide bar (3) and rotating shaft is coupled together, and loads onto detail pen (7) on slide bar (3).Like this, the mobile track of detail pen (7) is exactly an ellipse.
In like manner, change between slip pen and the slide bar and the connected mode between each slide bar, circle etc. is drawn in the circular arc of just can draw ovum circle, great circle, especially big radius and the uncertain center of circle again. With the drawing of this universal compass, picture speed is fast, lines are even, easy to use, can reach the purpose of a rule multipotency.
