Abstract
The utility model discloses a combined angle gauge, and in particular discloses a combined angle gauge convenient for drawing, belonging to school supplies. The combined angle gauge comprises an angle gauge, and is characterized in that a central rotation shaft is arranged at the arc-shaped circle center of the angle gauge and fixedly provided with a rotation ruler; the angle gauge is provided with an angle gauge datum line which penetrates through a zero scale and the central rotation shaft; and a rotation ruler is provided with a rotation ruler center line penetrating through the central rotation shaft. The combined angle gauge has the beneficial effects that the angle gauge datum line and the rotation ruler center line are respectively coincided with two sides of a detected angle, and the angle degree number of the rotation ruler on the angle gauge corresponds to the angle degree number of the detected angle. The combined angle gauge is convenient to use, and can measure any angle without drawing the extension line of the angle, and can be used for drawing any angles.
Description
Technical field
The utility model belongs to study article, the particularly a kind of combined type protractor that can conveniently draw.
Background technology
In the daily life, common angle gage structure is single, but angulation, but be inconvenient to the angle of drawing.
The utility model content
In order to overcome the inconvenient deficiency of existing protractor picture, the utility model provides a kind of combined type protractor, and this combined type protractor can not only be measured angular dimension, and the angle of conveniently drawing.
The utility model solves the technical scheme that its technical problem adopted: a kind of combined type protractor; Comprise protractor; It is characterized in that: the center of circle mounting center rotating shaft of protractor semi arch; Fixing one on the central rotating shaft and rotating ruler, protractor is provided with the protractor datum line that passes 0 scale and central rotating shaft, rotates ruler and is provided with the rotation ruler center line that passes central rotating shaft.
The beneficial effect of the utility model is that the protractor datum line is overlapped with the both sides of measured angle respectively with rotation ruler center line; The angle of rotating the correspondence of ruler on protractor is counted the angle number of measured angle, and the utility model extended line that need not the picture angle easy to use just can be measured arbitrarily angled.And any angle of can drawing.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Among the figure, 1. protractor datum line, 2. protractor 3. rotates ruler, 4. rotates ruler center line, 5. central rotating shaft.
The specific embodiment
The specific embodiment of the utility model is, and is as shown in the figure:
Embodiment 1; A kind of combined type protractor; Comprise protractor 2, it is characterized in that: the center of circle mounting center rotating shaft 5 of protractor semi arch, fixing one on the central rotating shaft and rotating ruler 3; Protractor is provided with the protractor datum line 1 that passes 0 scale and central rotating shaft, rotates ruler and is provided with the rotation ruler center line 4 that passes central rotating shaft.
