Ellipsograph

Abstract

The invention discloses an ellipsograph. The ellipsograph comprises a fixing frame body, wherein a fixing shaft seat is arranged at the top of the fixing frame body; a fixing shaft fixed to the fixingshaft seat is arranged at the bottom of the fixing frame body; a first bevel gear is fixed to the bottom of the fixing shaft; a rotating disc is rotationally connected to the fixing shaft; a rotatingplate and a first L-shaped plate are arranged at the bottom of the rotating disc; a sliding groove is formed in the middle of the rotating plate; the first L-shaped plate is fixed to the bottom of the rotating disc; the rotating plate is connected to the two sides of the first L-shaped plate through the sliding groove in a sliding manner; a second bevel gear matched with the first bevel gear is arranged on the first L-shaped plate; and a fixed plate fixed to the end part of the sliding groove is arranged on the side, close to the first L-shaped plate, of the bottom of the rotating plate. Theellipsograph has the advantages that the ellipsograph is designed according to the ellipse parameter equation principle, the axis of the fixing shaft is the center point of the ellipse, and the ellipse can be drawn directionally through the ellipsograph as long as the length of the major axis and minor axis of the ellipse to be drawn is determined.

Description

technical field [0001] The invention relates to the technical field of drawing tools, in particular to an ellipse gauge. Background technique [0002] The ellipse, as one of the conic sections, is often used in mechanical drawing, engineering drawing, or daily life study. Although the drawing software in the computer can draw an ellipse, it is often needed in daily study and work. To draw an ellipse, you can use the hand-painted method in some occasions, and the graphics are not accurate. In some occasions, such as mechanical drawing, the approximate drawing method is used, and the drawing method is cumbersome. Students often draw ellipses. Ellipse graphics are also used in the field, and the skills of drawing approximate ellipses are complicated. In these fields, there is no ellipse gauge that is more convenient to use and easy to popularize. Contents of the invention [0003] In order to solve the above technical problems, the technical solution provided by the present ...
