Embodiment Construction

[0006] Below in conjunction with accompanying drawing, the present invention will be further described: as shown in the figure, the data plate is provided with data bar, mark hole and the datum line with " 0 " point mark, five data bars of each row are a group, altogether 88 groups, each group The value in the first column from the left is the number of sides of the regular polygon, the value in the second column is the length of the side of the polygon, the value in the third column is the degree of the central angle opposite to the side, and the value in the fourth column is the opposite of the side The fraction of the central angle, the value in the fifth column is the number of seconds of the central angle of the side; each group of data columns has an indicator arrow next to it, and the angle between the arrow's reverse inflection point and the reference line is the angle between the reference line and the reference line. The number of angles in the data column of the grou...

Abstract

The invention relates to an equilateral polygon drawing data tablet, which is realized through the following scheme that data fields, marking holes and reference lines with zero point marks are arranged on the data tablet, five data fields in each line form one group, the number values in each group of fields are sequentially the edge numbers and the edge lengths of an equilateral (3 to 90) polygon and the degree, minute and second numbers of the central angle corresponding to each edge, and the equilateral polygon drawing data tablet is provided with a corresponding length and angle mode, the left lower part of the data tablet is provided with common angles and hollow circles with diameters being 1 to 15mm, the right lower corner of the data tablet is provided with a protractor, and the periphery of the data tablet is provided with several kinds of proportional scales in different proportions. The equilateral polygon drawing data tablet has the beneficial effects that one tablet has multiple purposes, and is convenient to use.

Description

Technical field: [0001] The invention relates to a drawing tool, in particular to a regular polygon drawing data board. Background technique: [0002] When drawing, not only a variety of drawing tools are needed, but also repeated calculations are required. Especially when drawing regular polygons, it is necessary to calculate first, then draw a circle, and then divide it with a compass, which is troublesome and sometimes causes large errors. Invention content: [0003] For the convenience of drawing, the present invention provides a kind of regular polygonal drawing data plate, and its plate body is provided with the number of sides, side length, and the number of angles of each side to the center of a regular (3-90) polygon on a circle with a diameter of 100 mm. At the same time, it is also equipped with the structural functions of protractor, ruler, scale, coordinates, circle of partial diameter, and triangular plate. It is realized through the following scheme: the dat...
