Abstract
The utility model discloses a pair of compasses which can measure and draw a certain angle. The main body of the utility model comprises a left gauge bar (1), a right gauge bar (2) and a circular arc ruler (3). One end of the circular arc ruler (3) is fixed on the left gauge bar (1). A fixation bolt (6) is positioned on the right gauge bar (2). An angle reticule (7) is marked on the circular arc ruler (3). The circular arc ruler (3) can slide on the fixation bolt (6) by a ruler sliding groove (4). When the two gauge bars are folded to a certain angle, the fixation bolt (6) is revolved tightly to fix the circular arc ruler (3), which fixes the two gauge bars at a certain angle. A small hole (10) is arranged above the circular arc ruler (3) and at a gauge bar reticule (8) on the right gauge bar (2). An index mark (5) is positioned under the circular arc ruler (3) and at the gauge bar reticule (8) on the right gauge bar (2). Both of the gauge bars are made of plastic. Each gauge bar central line is marked with the gauge bar reticule (8). By adopting the utility model, the compasses can be made to realize the functions of measurement and drawing angle. Therefore, the compasses and the goniometer can be combined into one, which reduces the drawing tools of the drawer and improves the drawing efficiency.
Description
Technical field:
The utility model relates to a kind of drawing tool, especially the improvement technology of compasses.
Background technology:
At present, the used compasses of people are to be used for the circle of picture certain radius mostly, and prior art always makes improvements in the precision to the drawn circle of compasses, and do not provide new function with regard to the improvement of compasses itself, improve the efficient of mapping.
Summary of the invention:
The purpose of the utility model:, improve mapping efficient by improving the function that increases compasses.
For realizing the utility model, intend adopting following technology:
The utility model is to fix a circular arc scale on two gauge bars, indicates the angle index line in the above, and two gauge bars make with transparent plastic material, and the center of every gauge bar indicates a groove.
The utility model characteristics:
Owing to adopt the utility model, can allow compasses realize measuring and drawing the function of angle, so just can collect compasses and protractor is one, has reduced mapping person's drawing tool, has improved mapping efficient.
Description of drawings:
Figure has illustrated structure of the present utility model.
1: left gauge bar; 2: right gauge bar; 3: the circular arc scale; 4: the scale chute; 5: index mark; 6: set bolt; 7: the angle groove; 8: the gauge bar groove; 9: the compasses center; 10: aperture.
Embodiment:
Main body of the present utility model is made of left gauge bar 1, right gauge bar 2 and circular arc scale 3, one end of circular arc scale 3 is fixed on the left gauge bar 1, on right gauge bar 2, be positioned with set bolt 6, circular arc scale 3 is marked with angle groove 7, circular arc scale 3 can slide on set bolt 6 by scale chute 4, two gauge bars are beaten to certain angle, and set bolt 6 screws with fixing circular arc scale 3, and with this two gauge bars is fixed on certain angle.Being arranged on has an aperture 10 on the gauge bar groove 8 on the right gauge bar 2 and above circular arc scale 3, being positioned at has index mark 5 on the gauge bar groove 8 on the right gauge bar 2 and below circular arc scale 3.Two gauge bars are made with transparent plastic material, and the center line of every gauge bar indicates gauge bar groove 8.
When measuring angle, the compasses accumbency is put in drawing, be opposite on the angular vertex with compasses center 9, again the gauge bar groove 8 on the left gauge bar 1 is aimed at the one side at angle, then right gauge bar 2 is opened to the another side at angle, the gauge bar groove 8 on it is aimed at this limit, overlaps with the both sides, angle to realize the gauge bar groove 8 on two gauge bars, the bolt 6 that is tightened just can be read the angle at measured angle by angle groove 7.
When drawing angle, on drawing, draw a straight line earlier, again with the gauge bar groove on the left gauge bar 18 and this adjusting to a line, compasses center 9 is aimed at this straight line one end points, according to the angle at the angle that will draw, 2 dozens of right gauge bars till this angle, are drawn a bit by aperture 10 places then, the end points that this and compasses center 9 are aimed at links to each other with straight line, just obtains required angle.The utility model also has the function of common compasses in addition.
Claims (5)
