Problems solved by technology

[0004] However, to project horizontal lines of different heights, the pointing device must move horizontally in the vertical direction
This is inconvenient on a construction site

Embodiment Construction

[0140] The present invention is described in detail below in conjunction with accompanying drawing:

[0141] The beam expander 10 that the present invention uses is as figure 1 shown. It contains a laser module 11 capable of producing a fine beam. The thin beam it emits is a beam expander optical component, a cylindrical mirror 12 in the figure, which expands into a fan-shaped beam FB in one direction, and it projects a straight line L on the target plane V.

[0142] like figure 2 As shown: when the beam expander 10 rotates around the Z-Z axis, the straight line L projected on the target plane v will move. figure 2 It is shown that a reflective optical component 13 is arranged on the fan-shaped beam emitted by the beam expander 10 to change the direction of the fan-shaped beam and project a straight line L on the target plane V. When the reflective optical assembly 13 is rotated around the Z-Z axis, the straight line L projected on the target plane H will also move.

Abstract

This invention unfurls a kind of simple horizontal projective device. It has a light beam expander which can circumvolve along the axis of Z-Z, a long bled that is fixed with it and is parallel with the axes of Z-Z, and a bled that is vertically placed on the whole with the long bled. The direction of the optical planar can be adjust with three adjusting nuts that are not in the same line. The two bleds is to show the aclinic direction of the optical planar. It also has a crossed beam of light which is composed of two groups of light beams to have parallel measure. Ascertain the parallelism between the plane and the axis from its intersection of the object plane. Circumvolve the adjusting wheel through a organ to beget the parallel movement of the intersection. By turning the light beam expander and the adjusting wheel, the projective device can not only project horizontal line with different height on the object plane in different distance, but also measure the distance between the device and the object plane.

Description

Technical field [0001] The invention relates to a simple horizontal line projection device, in particular to a projection device capable of projecting horizontal lines of different heights on target planes with different distances in a laser beam level measuring instrument. Background technique [0002] In interior decoration, a horizontal or vertical line is needed as a benchmark for measurement and determination. At the construction site, these reference horizontal lines or vertical lines should be determined; semiconductor lasers are often used to generate reference horizontal lines or vertical lines due to their small size, high brightness, and low price. [0003] In the applicant's previous patent "Automatic Laser Pointer" (Taiwan Patent Certificate No.: 159196), a device that can automatically generate a reference horizontal line or a vertical line has been described, mainly by a laser that can generate a thin beam. It consists of a radiation module, a beam expander a...
