Embodiment 1

[0039] A kind of retractable multifunctional conic gauge of the present embodiment is designed and manufactured according to mathematical principles. The basic principle of drawing an ellipse is that the sum of the distances from a point on the curve to the two focal points is a fixed value, and the basic mathematical principle of drawing a hyperbola is a curve The difference between the point above and the two focus distances is a constant value. The structure of this embodiment can easily realize and satisfy the curve equations of ellipse and hyperbola.

[0040] combine figure 1 , a telescopic multifunctional conic gauge of the present embodiment, comprising a handle 1, a rotating shaft 2, a gauge leg 3, a gauge leg 2 4, a drawing rod and a pin rod, and the drawing rod is passed through a screw 5, a nut 6 is connected with gauge leg one 3, and there are two stitch bars, represented by stitch bar A1 and stitch bar A2 respectively. The bottom of the second leg 4 is provided ...

Embodiment 2

[0045] combine figure 1 and Figure 4 , a kind of retractable multifunctional conic gauge of the present embodiment is basically the same as that of Embodiment 1, except that the present embodiment utilizes a protractor as the connector 7, the protractor is made of stainless steel, and a U-shaped diameter is set on the diameter of the protractor The column has a thickness of 5mm, and a cylindrical hole with a diameter of 3mm is dug in the middle, and the protractor can rotate in a planetary manner around the shaft installed in the cylindrical hole. The arc-shaped groove 9 is opened along the circumferential direction of the protractor, and the width of the arc-shaped groove 9 is 4 mm. A rectangular groove 8 is provided along the diameter direction of the protractor. The length of the rectangular groove 8 is 2 / 3 of the diameter of the protractor, and the width is 1.5 cm. One side of the length direction of the rectangular groove 8 is provided with equal millimeter scales. Thi...

Abstract

The invention discloses a retractable type multifunctional conic curve gauge and a drawing method and belongs to the technical field of drawing tools. The retractable type multifunctional conic curvegauge comprises a handle, a first gauge leg, a second gauge leg, a drawing rod and two pin foot rods. The drawing rod is movably connected with the first gauge leg; the two pin foot rods are both movably connected with the second gauge leg; a pen cap is arranged at the other end of the drawing rod and movably connected with the drawing rod; and pin caps are arranged at the other ends of the pin foot rods and movably connected with the pin foot rods. The basic structures and functions of existing compasses and existing dividers are reserved, and improvement is conducted based on the basic structures and functions of the existing compasses and the existing dividers; and the three-legged rod design is adopted, and a soft rope is matched so that the multipurpose effect of one gauge can be achieved, specifically, the gauge is a combined drawing tool having the functions of a pen, a ruler, a protractor, the compasses, the dividers, elliptic trammels, a hyperbolic curve gauge and a similar gauge for making lines similar to the tracks.

Description

technical field [0001] The invention relates to a retractable multifunctional conic gauge and a drawing method, in particular to a multifunctional conic gauge integrating a compass, a divider, an ellipse gauge and a hyperbolic gauge. Background technique [0002] Drawing circles, ellipses, and hyperbolas is something geometry teachers, students, and engineers often encounter. And so far, most of the manual drawing instruments are compasses, bipods, and line drawing pens, wherein compasses can draw circles or arcs of any radius, bipods can equally divide line segments, and templates can draw fixed dimensions and fixed curvatures. Ellipse, hyperbola and other graphics. However, existing drawing instruments cannot draw conic curves such as ellipses and hyperbolas with arbitrary parameters. The traditional geometric method of drawing an ellipse and a hyperbola is time-consuming and laborious. For example, the traditional ellipse drawing method first determines the two points (...
