Detailed description of the invention
The present invention is described further with embodiment below in conjunction with the accompanying drawings.
A kind of simple survey bevel protractor, as depicted in figs. 1 and 2, including disk the 1, first scale 2 and the second scale 3；Justifying
The circumference of dish 1 indicates the angle index 4 of 0 °-360 °；Described first scale 2 one end is fixing with disk 1 to be connected, and the first mark
Chi 2 is stretched out by 180 ° of disk 1 to 0 ° directions, and the other end of the first scale 2 is provided with the first groove 21 caved inward,
Being provided with the first laser lamp 22 in the first groove 21, described first laser lamp 22 is along the radially outward irradiation of disk 1；Described
Second scale 3 is provided with and extends vertically through the second scale 3 and extend to the notch 5 of second scale 3 one end, and described disk 1 is positioned at
In notch 5, it is flexibly connected with the second scale 3, and the junction point of the second scale 3 and disk 1 is positioned at the center of circle of disk 1；The
The other end of two scales 3 is provided with the second groove 31 caved inward, and is provided with the second laser lamp 32 in the second groove 31, described
Second laser lamp 32 is along the radially outward irradiation of disk 1；Described first laser lamp 22 and the second laser lamp 32 are positioned at and disk 1
In parallel plane；Described second scale 3 is made for transparent material；It is marked with indicatrix 6, described instruction at the second scale 3
Line 6 overlaps with the irradiation route of the second laser lamp 32；Including the battery electrically connected with the first laser lamp 22 and the second laser lamp 32.
This one simple survey bevel protractor, is connected owing to first scale 2 one end is fixing with disk 1, and the first scale 2 is by disk
180 ° of 1 stretch out to 0 ° of direction, then during use, chi on the basis of the first scale 2, can conveniently read measurement angle.
