Embodiment 1

[0029] like figure 1 As shown, the laser module of the line projector provided in this embodiment includes a light source assembly and an optical path assembly, wherein the light source assembly includes a laser collimation module 1, and the optical path assembly includes a first transflective glass 2, a second transflective Glass 3 , third transflective glass 4 , full-reflective glass 5 , first cylindrical mirror 6 and second cylindrical mirror 7 .

[0030] In this embodiment, the laser collimation module 1, the first transflective glass 2, the second transflective glass 3 and the first cylindrical mirror 6 are arranged in a straight line, and are all located on the first straight line A, while the full reflective glass, The third transflective glass and the second cylindrical mirror are arranged in a straight line, both located on the second straight line B; wherein, the laser collimation module 1 is located on the left side of the first transflective glass 2, and the second...

Embodiment 2

[0039] like figure 2 As shown, in this embodiment, in addition to the optical path components in Embodiment 1, the optical path assembly also includes a fourth transflective glass 8, and the fourth transflective glass 8 and the second transflective glass 3 are located on the third straight line C . The positions and arrangement angles of the fourth transflective glass 8 and the second transflective glass 3 are such that: the first point light is projected onto the fourth transflective glass 8, and the light part projected onto the fourth transflective glass 8 directly passes through the fourth transflective glass 8. The reflective glass 8 penetrates the second transflective glass 3 after partial reflection to form a third point of light. Wherein, in this embodiment, the first straight line is located in the y-axis direction, and the second transflective glass is set to form an angle of 45 degrees with the vertical plane (here, the plane formed by the x-axis and z-axis in the...

Embodiment 3

[0043] See you again figure 2 , the optical path assembly in this embodiment also includes a fifth transflective glass 9, the fifth transflective glass 9 and the third transflective glass 4 are on the fourth straight line D, the fifth transflective glass 9 and the third transflective glass 4 The position and arrangement angle are such that: after the second point of light is projected onto the fifth transflective glass 9, part of the light projected to the fifth transflective glass 9 directly penetrates the fifth transflective glass 9, and the other part is absorbed by the fifth transflective glass 9. Glass 9 is reflected and penetrates the third transflective glass 4 to form the fourth point of light.

[0044] Specifically, the fourth straight line D in this embodiment is a vertical straight line, and the third transflective glass 4 forms an angle with the horizontal plane, so that it can transmit a part of the light and project it onto the second cylindrical mirror 7, and ...

Abstract

The invention provides a demarcation device laser module and a laser demarcation device. The demarcation device laser module comprises a laser collimating module, first transmitting and reflecting glass, second transmitting and reflecting glass, third transmitting and reflecting glass, a first cylindrical mirror and a second cylindrical mirror; the laser collimating module, the first transmitting and reflecting glass, the second transmitting and reflecting glass and the first cylindrical mirror are located on a first straight line, and totally-reflecting glass, the third transmitting and reflecting glass and the second cylindrical mirror are located on a second straight line; the laser collimating module is located on the first side of the first transmitting and reflecting glass, the second transmitting and reflecting glass and the first cylindrical mirror are located on the second side of the first transmitting and reflecting glass, and the totally-reflecting glass is located on the third side of the first transmitting and reflecting glass. The demarcation device laser module can be further configured to comprise fourth transmitting and reflecting glass and fifth transmitting and reflecting glass. The demarcation device laser module achieves light output with one light source, two points and two lines and four points and two lines, cost is effectively saved, and it is more beneficial for miniaturization design of the size.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for engineering construction, in particular to a laser module of a line thrower and a laser line thrower. Background technique [0002] Cross line laser, also known as laser line marking instrument, is a laser beam that uses a cylindrical lens or a glass rod to form a fan-shaped laser surface, which is projected to form a horizontal and / or vertical laser line. The instruments are mostly used in decoration and other fields. [0003] When existing laser line projectors need to project horizontal lines and vertical lines at the same time, it is generally necessary to set a horizontal line projection laser head and a vertical line projection laser head respectively. For example, in the Chinese invention patent application with publication number CN104515511, the laser provided In order to realize multi-angle line casting, the line casting instrument is equipped with forward vertical line projecting...
