[0038] The multi-purpose laser line projector according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 3 As shown, the multi-purpose laser line projector provided in an embodiment of the present invention includes: a bracket 10, a shell 20 and a laser assembly 30. The shell 20 is rotatably arranged on the bracket 10 and is respectively provided with a first projection window 201 and a second projection window 202 on mutually perpendicular planes; the laser assembly 30 is arranged in the shell 20, and is used to output a first laser beam through the first projection window 201 and output a second laser beam through the second projection window 202.

[0040] The multi-purpose laser line projector provided by the utility model can support the laser line projector horizontally through the bracket 10, and then output the first laser beam and the second laser beam through the laser component 30, so that the first laser beam can be output from the first projection window 201 and the second laser beam can be output from the second projection window 202, thereby realizing horizontal adjustment in two directions, improving the adjustment efficiency and making the functions more diversified.

[0041] Specifically, the bracket 10 includes a support frame 11, a support base 12, and an adjustment member 13. The support base 12 is pivotally mounted on the support frame 11. The adjustment member 13 is mounted on the support base 12 and is used to adjust the pivoting of the support base 12. The laser line projector can rotate in the roll direction on the support base 12, and the support base 12 can rotate in the pitch direction relative to the support frame 11, thereby making it easier to adjust the emission directions of the first and second laser beams.

[0042] Furthermore, the housing 20 has an incident channel 203 , a first exit channel 204 and a second exit channel 205 . The first exit channel 204 and the incident channel 203 are on the same axis, and the first exit channel 204 and the second exit channel 205 are perpendicular to each other.

[0043] Specifically, the laser assembly 30 includes: a laser 31, a lens 32 and a beam splitter 33. The laser 31 is arranged in the incident channel 203; the lens 32 is arranged in the incident channel 203 and is located in the light output direction of the laser 31; the beam splitter 33 is arranged at the intersection of the incident channel 203, the first output channel 204 and the second output channel 205, so as to project the laser beam emitted by the laser 31 into the first output channel 204 and the second output channel 205 respectively.

[0044] In this embodiment, the lens 32 is a collimating lens 32. After the laser 31 emits a laser beam, the laser beam can be adjusted to a parallel laser beam through the lens 32, and the laser beam can be split by the beam splitter 33, so that the laser beam can be output toward the first output channel 204 and the second output channel 205 respectively to achieve horizontal measurement in different directions.

[0045] Furthermore, the laser assembly 30 also includes: a first beam combining mirror 34 and a second beam combining mirror 35. The first beam combining mirror 34 is arranged in the first output channel 204, and is used to focus the laser beam output by the beam splitter 33 to output a first laser beam; the second beam combining mirror 35 is arranged in the second output channel 205, and is used to focus the laser beam output by the beam splitter 33 to output a second laser beam.

[0046] In this embodiment, the laser beams entering the first output channel 204 are combined by the first beam combiner 34 to generate a first laser beam, and the laser beams entering the second output channel 205 are combined by the second beam combiner 35 to generate a second laser beam, so that the first laser beam and the second laser beam can form a straight line, so that the first laser beam is output from the first projection window 201 and the second laser beam is output from the second projection window 202, thereby realizing horizontal adjustment in two directions; optionally, the laser wavelength emitted by the laser 31 is 580-720nm.
