Description
Technical field
The invention belongs to drawing tool technical field more particularly to a kind of compasses for drawing ellipse and positive round and its users
Method.
Background technique
In mathematics, ellipse is the curve in the plane of two focuses, so that for each point on curve, to two
The sum of the distance of a focus is constant.Therefore, it is the summary of circle, is that there are two focus is special at same position for tool
The ellipse of type.Elliptical shape (how " extending ") is indicated by its degree of eccentricity, can be the limit feelings from 0(circle for ellipse
Condition) arrive any close but any number less than 1.Ellipse is closed conic section: the Plane Curved intersected by cone with plane
Line.The oval conic section with other two kinds of forms has many similarities: parabola and hyperbola, both open sum
Unbounded.The cross section of cylindrical body is ellipse, unless the section is parallel to the axis of cylindrical body.
It is frequently necessary to carry out ellipse drawing on classroom, is also required to draw ellipse in operation in student, but currently without special
The tool of door can allow teacher accurately to draw out ellipse on blackboard, and often freehand is oval.It is not only not quasi- enough in this way
Really, the thinking of normally solving a problem of students is had an effect on.There is data to show, can draw elliptical instrument at present there are two classes.The first kind
It is traditional compasses, it is made of the bottom plate, spinner handle and slide sign of cross sliding slot, passes through rotation slide sign composition.But it is due to body
It is huge, only a kind of teaching aid at present.And it is limited to sliding slot in length and breadth, the ellipse that can be drawn is very limited.Second class is oval drawing
Instrument, it is Student ellipsograph.But this ellipsograph, operation is comparatively laborious, and drawing processes are clumsy, and drawn ellipse is not to advise very much
Model, key is drawn, and the time is longer, and obviously it is impossible to meet our demands for these.
In the prior art, do not occur also that oval and positive round tool can be drawn simultaneously, people need when drawing positive round and ellipse

Working principle
When starting picture ellipse, the positioning screw 508 for selecting length to be not much different with drawn oval two focus length allows positioning screw
508 sequentially pass through the left side hole 506 not with threaded hole, threaded hole 26, the right hole 506 not with threaded hole, form one
A straight line；
Then rotation spiral vertical bar 509 is stirred, realizes the lifting of connecting plate 501, focus pilot pin 505 is adjusted and the oval heart positions
The distance of needle 6, the distance between two focus pilot pins in left and right are equal to drawn oval focal length, and oval heart pilot pin 6 is ellipse at this time
On the center of circle, oval heart pilot pin 6 and two focus pilot pins 505 be with paper contact condition；
Then main control axle sleeve 1 is pressed downwards, and by the effect of thin bar spring 22, main control axle sleeve 1 drives auxiliary control shaft 3 and master control
Axis 2 processed keeps balance, rotates silk thread winding wheel 507, and pencil-lead fixing sleeve 4 is made to be equal to required a at a distance from oval heart pilot pin 6
Or the value (a is that semi-major axis is long, and b is that semi-minor axis is long) of b, and the silk thread in silk thread perforation 8 is made to be in exceptionally straight state；The oval heart at this time
Distance required for pencil stub in 6, two focus pilot pins 505 of pilot pin, pencil-lead fixing sleeve 4, which is adjusted, to be finished, and same
When contacted with paper；
Auxiliary 3 half cycle of control shaft is rotated, auxiliary control shaft 3 drives the pencil stub in pencil-lead fixing sleeve 4 to draw elliptical half, then
Auxiliary control shaft 3 is rotated into opposite, then half rotation, draw it is oval the other half；
It when needing picture positive round, first passes through and stirs spiral vertical bar 509 and ramp up focus fixed axle structure 5, keep two focuses fixed
Position needle 505 is higher than oval heart pilot pin 6, then according to the good oval heart pilot pin 6 of the diameter adjustment of positive round and pencil-lead fixing sleeve 4
Position after, i.e., round radius, by locking nut 92 from the right end of threaded rod 93 is adjusted to left-handed, rotation to auxiliary control shaft 3
Contact, the compasses that the present invention can be used as picture positive round at this time use, and drive auxiliary control shaft 3 to rotate by main control axle sleeve 1, auxiliary control
Axis 3 processed drives the pencil stub in pencil-lead fixing sleeve 4 to draw positive round.
Using technical solutions according to the invention or those skilled in the art under the inspiration of technical solution of the present invention,
Similar technical solution is designed, and reaches above-mentioned technical effect, is to fall into protection scope of the present invention.
