Abstract

The utility model relates to a curve gauge, which belongs to the stationery, particularly a tool for drawing curves. According to the design proposal provided by the utility model, a ruler is provided with a slide groove, and a pulley which can slide is arranged in the slide groove; the end part of the ruler is provided with a pin shaft and an angle square additionally; an included angle is arranged between the ruler segment and the angle square segment of the angle square; the ruler segment is likewise provided with a slide groove and a pulley which can slide in the slide groove; the end part of the angle square segment is provided with a pin shaft. The utility model can conveniently draw curves, and the work efficiency and the drawing quality can be enhanced.

Description

Curve gauge
Technical field
The utility model relates to stationery, specifically a kind of instrument that is used for curve plotting.
Background technology
In school instruction and engineering design; often can use curve; for some comparison rule curves,, can draw with compasses as circle, arc etc.; curve for some more complicated; as curves such as ellipse, hyperbola, parabola, involute, helixes, also there is not special-purpose drawing tool at present, adopt the mode of coordinates computed point to draw usually; cumbersome, also inaccurate.
Summary of the invention
The purpose of this utility model is to design a kind of curve gauge, to make things convenient for curve plotting, increases work efficiency and rendering quality.
According to design provided by the utility model, on a ruler, chute is set, the pulley that can slide is arranged in chute, end at ruler is provided with bearing pin, and other has an angle square, between the ruler Duan Yuqi of this angle square angle square section angle is arranged, the pulley that on the ruler section, chute is arranged equally and can in chute, slide, end in the angle square section is provided with bearing pin, and the pulley sleeve on the ruler is on the bearing pin of angle square, and the pulley sleeve on the angle square is on the bearing pin of ruler.
When utilizing the utility model to come curve plotting, can receive the effect of getting twice the result with half the effort.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in the figure: on a ruler 1, chute 3 is set, the pulley 2 that can slide is arranged in chute 3, in the end of ruler 1 bearing pin 5 is set, other has an angle square, between the ruler section 4 of this angle square and its angle square section 6, angle is arranged, pulley 2 chute 3 being arranged on the ruler section 4 equally and can sliding in chute 3 is provided with bearing pin 5 in the end of angle square section 6.During use, pulley on the ruler 12 is enclosed within on the bearing pin 5 of angle square, pulley 2 on the angle square is enclosed within on the bearing pin 5 of ruler 1, tape deck 7 is installed on ruler 1, mobile ruler 1, it is mobile that the bearing pin 5 of ruler 1 is driven in the chute 3 of pulley 2 on the ruler section 4 of angle square on the angle squares, and in moving process, the tape deck 7 on the ruler 1 is at the corresponding curve that draws on the paper or on other recording equipment.The instrument of this curve plotting also is the simple and easy diagram of curvilinear cut processing and Machining of Curved Surface in industrial practice.
