Level and/or verticality indicator using laser beams

Abstract

A levelness and or vertically indicator using a laser beam is provided in which a laser beam emitted from a laser beam scanning mechanism (4) is converted to a laser beam line by using a cylindrical lens (145) or a polygonal rotary mirror and the laser beam line is used for indicating levelness and or vertically and a vertical point with the bear eyes by a calibration process for matching the laser beam line with a reference levelness line. The levelness and or vertically indicator includes a laser diode (50a) for emitting a laser beam, a laser beam converting and outputting unit for converting the received laser beam and outputting the converted laser beam, and a portion for providing a reference levelness so that the laser beam line output from the laser beam converting and outputting unit maintains the reference levelness. Also, the pendulum movement of a weight plumb (94) is stopped quickly due to magnetic resistance so that the real levelness and vertically and a vertical point are convenient are indicated by using a laser beam. Thus, the time and work amount needing for indicating levelness and or verticality is reduced. Further, when a an object to be worked on is huge, levelness and or verticaly can be effectively indicated.

Description

technical field [0001] The present invention relates to a levelness and / or plumbness indicator using a laser beam, and in particular relates to a levelness and / or plumbness indicator using a laser beam by emitting a laser beam from a scanning mechanism The laser beam is converted into a laser beam line, and the laser beam line is output while maintaining the reference level. Background technique [0002] In general, when constructing a building structure at a construction site, the level is indicated by allowing an air bubble formed in a liquid-filled and sealed glass tube to be located at the center thereof to adjust the level. Then, a line or a steel wire is positioned corresponding to the horizontal plane, so that the stacked bricks or timber can be placed horizontally on the horizontal plane or the horizontal line accordingly. In addition, to set the plumb line, a plumb weight attached to the line is used, and a column is erected corresponding to the plumb line. Thus, ...

Problems solved by technology

In addition, although a level indicator can be used under a microscope at each position, it also makes horizontal and vertical work difficult due to the inability to observe the target with a microscope

Although there are many kinds of laser pointers, the ability of ordinary laser pointers to indicate the laser beam line, its production and control methods are very difficult, which makes the price of this pointer high, and some use methods are very complicated, and users are also very difficult. Difficult to learn, reducing productivity in the workplace
