The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.Among Fig. 1,2,3,4, novel ellipsograph is made up of support 1, long shaft rod 2, stub shaft 3, bracket slide 4, long shaft rod slide block 5, stub shaft slide block 6, nib fixed mount 7, knob 15, described support 1 both sides are provided with chute 16, carriage center is provided with through hole 17, and bottom, support two ends is provided with bearing 18; Long shaft rod 2, stub shaft 3 all are located at support 1 bottom, and an end of described long shaft rod 2 is provided with perpendicular fixedly connected cylinder 19; Described bracket slide 4 is entrenched in the chute 16 of support 1 both sides, and be slidingly connected with it, one end of bracket slide 4 bottoms and stub shaft 3 is rotationally connected, the other end of stub shaft is located in fixed mount 7 and the stub shaft slide block 6 and can be slidingly connected with it, one end of described long shaft rod 2 is located in the long shaft rod slide block 5 and can be slidingly connected with it, the other end of long shaft rod 2 is rotationally connected by the central through hole 17 of cylinder 19 with support 1, and cylinder 19 is paid with the knob that is located at support top and is connected.
Be equipped with trip bolt 8,9,10 on described major axis slide block 5, minor axis slide block 6, the nib fixed mount 7.
Be equipped with graduated scale on described long shaft rod 2 and the stub shaft 3.Described support 18 bottoms are provided with sucker 13,14.
Among Fig. 5, described nib fixed mount 7 bottoms are provided with the spring 20 of fixedlying connected with it, and the other end of spring 20 is fixedlyed connected with the pen cap 11.
The picture equation is
Oval the time, regulate the position of major axis slide block 5 and stub shaft slide block 6 as requested, making long shaft rod slide block 5 and stub shaft slide block 6 centers all is (a+b)/2 and fixing to the distance at support 1 center, regulate nib fixed mount 7 positions then, the center that makes nib fixed mount 7 is b and fixing to the distance at bracket slide (4) center.Stub shaft slidably reciprocates once along the chute on the support 1, and long shaft rod will rotate around the through hole of support a week so, and the track of paintbrush on paper is
Ellipse.
Operating process of the present utility model is: drawing paper is placed on the desktop, and novel ellipsograph just is being placed on the paper, holds desktop with fixing with sucker 13,14, and the ellipse of establishing required picture is
, long shaft rod 2 and stub shaft 3 are transferred to the position vertical with support 1, they are in the same side of support 1.Turn on trip bolt 8,9 and regulate the position of long shaft rod slide block 5 and stub shaft slide block 6, make these two slide block centers tighten trip bolt 8,9 again for (a+b)/2 to the distance of carriage center, turn on trip bolt 10 then and regulate the position that can tighten fixed mount 7, making its center and the distance at bracket slide 4 centers is b.Slide block 4 on the sliding support groove more afterwards, the slip of slide block 4 can drive long shaft rod 2 and rotate the hybrid motion of stub shaft 3 around the hole of support.Can occur dead point with long shaft rod 2 during at same straight line when slide block 4 slides into stub shaft 3, rotate the knob 15 that long shaft rod 2 protrudes above this moment, is driving link with long shaft rod 2, and slide block 4 is a driven member, can be driving link with slide block 4 again after waiting slide block 4 to skid off the dead point district.Long shaft rod 2 can be around 17 1 weeks of rack ventilating hole time a time when slide block slidably reciprocates, and paintbrush just can draw on paper one and meet
Ellipse.Long shaft rod 2 is marked with scale with stub shaft 3.Elder generation is according to the equation of ellipse in use
In parameter a, b determines the position of long shaft rod slide block 5, stub shaft slide block 6 and nib fixed mount 7.But make long shaft rod piece 5 centers be to the distance at bracket holes center
, the distance at stub shaft slide block 6 centers and bracket slide 4 centers also is
, nib fixed mount 7 centers are that (to be nib fixed mount 7 be b to the distance at stub shaft slide block 6 centers to the distance at slide block 4 centers
).Be listed as follows:
