Abstract
The utility model belongs to a drawing instrument for providing a draw oval ellipsograph, its key feature is that this kind of ellipsograph is perpendicular cross, respectively has a ventilative spout in the middle of two rails of moving about freely and quickly, respectively adorns an activity sliding vane on the spout of moving about freely and quickly, has a swing arm below the spout, and this swing arm is even as an organic whole with two sliding vanes of moving about freely and quickly, removes the sliding vane, and 360 rotating drawing ellipses can be done to the swing arm below it. The ellipsograph is simple in processing and manufacturing, rapid, standard, convenient and practical in use, and is a necessary tool for drawing especially ellipses.
Description
The invention belongs to the drawing instrument class, especially for drawing oval a kind of instrument.
Since the dawn of human civilization, preceding people have accumulated rich knowledge and experience for the picture ellipse, have also created many efficient ways.So far as I know, an also not following kind how ten! But have or not so far the people utilize these knowledge and method make a kind of easy, draw the Ellipse tool accurately, efficiently, flexible as other drawing instrument, the convenient use.
The invention provides a kind of oval ellipsograph of drawing, in drawing work, draw oval problem to solve.
The structure of ellipsograph mainly is made up of cross rail and two members of swing arm.Member is all made of metal material, and particularly cross rule will be made of the big on-deformable metal material of hardness.Also available lucite or the big plastic processing of hardness.
The cross rail is equivalent to axes of coordinates in length and breadth, and it is the chute (neck down portions of X-shaped wide be 2mm) of X-shaped that free and cross section is arranged on its axes of coordinates.It is absolute orthogonal and smooth that the groove of rail in length and breadth of cross rail is wanted, and will be in one plane.All there is vertical with the cross rail groove angle pin that is about about 15mm four terminations of cross rail.Four pin pin needle points will be on a horizontal plane, and overlaps with rail groove axis.Each card has cursor type transversal of a slip to be the slide sign of X type between the rail groove in length and breadth.Slide sign is stuck in separately can only be done up and down in the rail groove or horizontally slip and do not disturb mutually.The upper end of slide sign is an operating grip, and 360 ° of rotations can be done in the lower end, has a rectangle hole therebetween, and a fixed screw is arranged at the bottom of the hole.X type slide sign is controlled on the rail groove and slides and the rail groove is wanted suitable driving fit, and coefficient of friction is the smaller the better, otherwise is inconvenient to use.
Swing arm is slightly to be longer than half rod member of rail groove, be carved with the millimeter its side is the scale of long measure, section configuration is identical with slide sign lower end aperture, it is set in the aperture of two X-shaped slide sign lower ends, screw just can be fixed on two slide signs on the swing arm at the bottom of screwing the hole, make swing arm along with slide sign when the intercropping of rail groove is slided up and down and self do 360 ° turn.The front end of swing arm (being the outer end) is equipped with the vertical fixed sleeving that internal sealing plug is arranged, peace cored screw in the sleeve pipe, and pen core or special pen can be adorned in the screw rod lower end.Ellipsograph textural to pay special attention to be: when the swing arm band pen core head rotation with cross rail groove when superimposed, the line of its axis and its corresponding two angle pins (promptly axes of coordinates) in length and breadth will be able to overlap, otherwise drawn oval irregular.This just requires ellipsograph to make and wants accurate, and operation will be apt to debugging.
The neglecting it greatly and need the oval size of picture and decide of ellipsograph.As the length of the general cross rail of drawing instrument, be advisable (changeable) as the teaching time spent with 20 centimetres.Major radius can both draw with ellipsograph with interior any ellipse figure at 10 centimetres.
The ellipsograph processing and manufacturing is simple, and is with low cost, use light and handy, convenient, than other draw that oval instrument is quick, standard, practicality, be a kind of comparatively desirable widely used drawing appliance.
Close accompanying drawing followingly, be described further with regard to its structure and method of operating:
Accompanying drawing 1 is overlooked organigram for ellipsograph
Accompanying drawing 2 is an ellipsograph vertical section organigram
Accompanying drawing the 1, the 2nd, a kind of ellipsograph, it has two cross rails 1 in length and breadth, interior respectively have a saturating empty chute 2, respectively be with on the chute 2 slide sign 3,6 and above slide sign lever 4,5.Article two, four of cross rail end points respectively have an angle pin 10, four pin pins 10 should debug on a horizontal plane.Below the saturating empty chute 2 of cross ellipsograph, a swing arm 7 that connects together with slide sign 3,6 is in length and breadth arranged, the end points of swing arm 7 has moving casing 8, loads onto pen core 9 in the sleeve pipe 8, and swing arm 7 can be made 360 ° the turn needed ellipse that draws with the central point on the cross rail.
The method of manipulating of ellipsograph:
The first step: drawing paper is laid on the drawing board, on paper, retouches out the position coordinates of drawn ellipse then, and on coordinate in length and breadth, measure the length radius of drawn ellipse respectively.
Second the step: four angle pins 10 of ellipsograph respectively aiming axis put well, make the cross rail in length and breadth the axle overlap with coordinate on the drawing.
The 3rd goes on foot: swing arm 7 (being with slide sign 6) is transferred to the transverse axis coordinate overlap two slide sign lower end fixed screws 11 of (longitudinal axis slide sign 3 must occupy 0 point at this moment) sth. made by twisting pine, make the swing arm 7 end pen cores 9 aim at required major radius, and twist with the fingers tight longitudinal axis slide sign 3 (occuping at 0) fixed screw 11; Spur longitudinal axis slide sign 3 handlebars 4 then to lower slider, spurring transverse axis slide sign 6 handlebars 5 simultaneously slides left, make swing arm overlap (at this moment transverse axis slide sign 6 must occupy 0 point) with the longitudinal axis, and make pen core point 9 aim at required short radius, twist with the fingers tight transverse axis slide sign 6 fixed screws 11 then, all finish to this preparation.
The 4th step: regulate the hollow screw mandrel 8 of swing arm 7 front ends, make pen core point 9 touch paper, spur two slide sign handlebars 4,5 then slogan banner is horizontally slipped; Make the vertical lower slider of putting on, with swing arm 7 turn toward the clockwise direction that two marks link to each other, 9 of pen core points describe its oval-shaped track on drawing.
In describing process, if pen core 9 can not contact paper, the shape of tracing designs just unintelligible.Then regulate hollow swing arm 8 in the direction of the clock, make lead for retractable pencil 9 contact papers, the shape of tracing designs just clear.Describe to finish,, make lead for retractable pencil 9 leave paper, remove ellipsograph from drawing then, tidy up and pick up, in order to using again by counterclockwise regulating lead for retractable pencil 9.
If institute's generating writing pattern does not require fixing position, coordinate then needn't draw on drawing earlier, just regulate the major radius that longitudinal axis slide sign 3 distances to pen core point 9 equal drawn ellipse according to the scale on the swing arm 7, tighten longitudinal axis slide sign 3 following fixed screws 11 then, swing arm 7 is fixed in longitudinal axis slide sign 3 square holes; Distance between two slide signs 3,6 transfers to and equals the poor of oval length radius, tightens below the transverse axis slide sign 6 fixed screws 11 then again and just ellipsograph can be positioned on the paper and directly describe by above operating procedure.
