Geometry coordinate machine

Abstract

The invention relates to a geometrical coordinate machine which is composed of the geometrical coordinate machine, a narrow ruler gauge, a radial hole, a protractor, the centre of a circle, a metric scale, a working edge, a foot rule, the working edge of the foot rule, a chi ruler, a ruler gauge, a surveying slot, a digit, a graduation and a nodal wood hole; the centre of the circle of the protractor of the geometric coordinate machine and the metric original point of the metric scale are arranged at the same point; the initial side of the zero angle of the protractor and the working edge of the metric scale are in the same line; the radial hole of the ruler gauge is arranged on the graduation of the metric scale, the foot rule and the chi ruler to align the ordinal number of a radius; the surveying slot is opened between the edge composed of the initial side of the zero edge of the protractor and the working edge of the metric scale and the working edge of the adjacent foot rule; the binding site of the metric scale, the foot rule, the chi ruler and the protractor can be arranged interchangeably; the radial hole of the narrow ruler gauge is distributed and combined on the graduation. Compared with the prior art, the geometrical coordinate machine has the advantages of more reasonable structure, faster surveying rate, small materials consumption, and convenient use, storage and carrying and can play the roles of surveying an angle, a length and a round .

Description

Technical field [0001] The present invention relates to a geometric surveying and mapping instrument, which is specifically composed of a ruler, a radius hole, a protractor, a metric ruler, an imperial ruler, a city ruler, a surveying and mapping groove, a number, a scale, and a material-saving hole, which is suitable for geometric surveying and mapping. Background technique [0002] The existing geometric tools of 360 measuring angle, straightedge, compasses are divided into pieces, and the surveying and mapping speed is not fast. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the 360-degree measuring angle device, which is separated from the ruler and compasses, and to provide an integrated 360-degree measuring angle device that is integrated with the straightedge and compasses to improve the measurement and drawing rate of geometrical surveying and mapping. The technical content of the instrument is as...
