Embodiment 1

[0022] Such as figure 1 and Figure 4 As shown, the present invention mainly consists of coordinate frame 1, horizontal line wheel 2, vertical line wheel 3, V-shaped frame 4, telescoping line 5, coil spring 6, sliding bar 11, slider 12, pen cap 13, thread nozzle 21, horizontal liner Wire wheel fixing button 22, rotating wheel 41 and connecting wire 51 form. The coordinate frame 1 is L-shaped, and a chute is arranged on the coordinate frame 1 . The V-shaped frame 4 is formed by combining two straight strip-shaped objects through the rotating wheel 41, and the two straight-strip-shaped objects of the V-shaped frame 4 can rotate around the rotating wheel 41; One end of frame 4, longitudinal wire wheel 3 is located at the other end of V-shaped frame 4;

[0023] Such as image 3 As shown, a wire groove is provided on the outer circumference of the horizontal wire wheel 2, and a wire hole 23 is provided in the wire groove.

[0024] The longitudinal wire wheel 2 has the same str...

Embodiment 2

[0034] The difference between this embodiment and the first embodiment is that the coil spring 6 is arranged in the weft wheel 2, the stretching wire 5 and the connecting wire 51 are wound in the same direction on the weave wheel, and the winding direction on the weave wheel 3 is opposite.

[0035] The present invention is used in this way: because the return tension of the coil spring makes the telescopic wire and the connecting wire in a tight state; first fix the midpoint of the telescopic wire between the two nozzles at the pen holder, and then Use the horizontal line wheel fixing button to fix the horizontal line wheel at the corresponding position of the coordinate frame and insert the brush into the pen holder, then move the sliding rod upwards, and keep the entire part of the telescopic line in a tight state during the movement , then the place where the brush goes is the place where the trajectory of the parabola passes.

Abstract

The invention discloses a parabola gauge which structurally comprises a coordinate frame, a transverse line wheel, a longitudinal line wheel, a V-shaped rack, an extensible line, a coil spring, a slide rod, a slide block, a pen cap, line nozzles, a transverse line wheel fixing button, a rotary wheel and a connecting line, wherein the slide block is arranged on the slide rod; the slide block can slide on the slide rod; and the front end of the slide block is provided with the ring-shaped pen cap. The extensible line is arranged between the transverse line wheel and the longitudinal line wheel; one end of the extensible line is wound in a line slot in the transverse line wheel; the other end of the extensible line is wound in a line slot of the longitudinal line wheel; and the extensible line penetrates through the two line nozzles. The extensible line and the connecting line are of an integrated structure. The parabola gauge has the beneficial effects of being capable of conveniently and precisely drawing out various needed parabolas.

Description

technical field [0001] The invention relates to an instrument, in particular to a parabola gauge for drawing a parabola curve. Background technique [0002] There is no such simple and convenient parabolic gauge at present. Contents of the invention [0003] The problem to be solved by the present invention is to provide a parabolic gauge with simple structure, convenient operation and accurate line drawing. [0004] In order to solve the above technical problems, the technical solution of the present invention is as follows: [0005] A parabolic gauge, the structure of which includes a coordinate frame, a horizontal line wheel, a vertical line wheel, a V-shaped frame, a telescopic line, a coil spring, a sliding rod, a slider, a pen cover, a thread mouth, a horizontal line wheel fixing button, a rotating wheel and a connecting line; the coordinate frame is L-shaped, and a chute is provided on the coordinate frame. The V-shaped frame is formed by combining two straight b...
