Description

translational measurable multi-purpose large compasses

Technical field:

The utility model belongs to the technical field of drawing tools, and in particular relates to a multi-purpose compasses with measurable translation.

Background technique:

The traditional compass used to draw a circle is generally composed of outriggers, a center pin, a marking rod and a handle. When people draw a circle, they need to use a ruler to measure the distance between the center pin and the marking rod to determine After drawing the radius of the circle, turn the handle to draw the desired circle on the paper with the center pin as the center. Drawing a circle requires at least a ruler and a compasses. Two drawing tools are more troublesome to operate.

In addition, in traditional compasses, after the center needle and the marking rod are opened at a certain angle, the angle between the center needle and the marking rod and the paper surface is less than 90°, which is not conducive to the positioning of the center needle, and is also not conducive to when the marking rod marks the line. The control of line width is also very inconvenient to operate.

In addition, traditional compasses are limited by their structure and size, and the radius of the circle drawn is limited, so a circle with a larger radius cannot be drawn.

In order to solve the above-mentioned technical problems, technicians have developed some new types of compasses, and some technicians have also developed compasses in which the marking rod 8 moves along a ruler with a scale, such as the patent No. "ZL201220757302. Chinese utility model patent, it fixes the leg of the compass to one end of the ruler, and the pen leg of the compass slides along the ruler, so that the radius of the circle drawn can be determined, and the leg and the pen leg are perpendicular to the paper surface. But, as everyone knows, when drawing a circle, the radius of the circle is realized by measuring the tip of the compass leg and the tip of the pen pin, but in this patent, the measurement of the radius of the circle is by measuring the side of the leg and the tip of the pen pin The center position of the slider, the radius of the circle obtained is not accurate, it is not the real radius of the drawn circle, resulting in inaccurate drawing. For example, the patent application number is "201110295126.2", and the patent name is a Chinese invention patent of "a kind of ruler and compass". Above", however, the patent does not disclose how to achieve this structural limitation. In addition, the verticality between the ruler and the positioning legs is only adjusted by the manual operation of the draftsman, and the accuracy is not high, or it depends on a set square or a protractor. It is troublesome to operate other drawing tools. For example, the patent application number is "200910063031.0", and the Chinese invention patent named "dual-purpose compass", the drawing needle rod of this patent moves along the ruler through the sliding sleeve, and the radius of the drawn circle is determined by the reading on the ruler, but, In this patent, the lower end of the fixed needle rod and the lower end of the needle drawing rod cannot clearly correspond to the scale on the ruler, the radius of the circle drawn does not correspond to the reading of the ruler, and the radius of the circle drawn is inaccurate.
