Description

Technical Field

[0001] This utility model relates to the field of laser device technology, and in particular to a cross laser module and a laser line projector. Background Technology

[0002] Laser line projectors are commonly used measuring instruments in construction and home renovation. They emit vertical or horizontal visible lasers to mark horizontal or vertical lines on a target surface. Their core component is the laser module, and its accuracy directly affects the overall accuracy of the instrument.

[0003] A typical cross-shaped laser module usually includes a first cylindrical mirror and a second cylindrical mirror, used to generate horizontal and vertical laser lines respectively. The perpendicularity of the first cylindrical mirror to the laser beam is adjusted by a first adjusting screw. Simultaneously, multiple second adjusting screws are arranged relatively parallel to the axis of the second cylindrical mirror, used to adjust the position of the second cylindrical mirror relative to the first cylindrical mirror to achieve orthogonality and straightness of the laser lines. However, in actual structural design, all the second adjusting screws act on the same plane, causing mutual interference between the screws during adjustment. This complicates operation and makes it difficult to achieve precise adjustment of the second cylindrical mirror's position, thus affecting the straightness of the laser line generated by the second cylindrical mirror and the perpendicularity between the laser lines generated by the two cylindrical mirrors.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0039] The first aspect of this utility model provides a cross laser module, such as... Figure 1 and Figure 2 As shown, it includes a lens barrel 1, a first mounting base 2, a second mounting base 3, a first cylindrical mirror 4, and a second cylindrical mirror 5;

[0040] The lens tube 1 is configured to emit a first laser beam and a second laser beam to the first cylindrical mirror 4 and the second cylindrical mirror 5, respectively;

[0041] The first cylindrical mirror 4 is mounted on the first mounting base 2. The first mounting base 2 is connected to the mirror tube 1 and is provided with a first adjustment structure 6 between the first cylindrical mirror 4 and the first laser beam for adjusting the perpendicularity of the first cylindrical mirror 4 to the first laser beam.

[0042] The second cylindrical mirror 5 is mounted on the second mounting base 3. The second mounting base 3 is connected to the first mounting base 2 and is provided with a second adjustment structure 7 between the axial end face of the first mounting base 2 for adjusting the perpendicularity of the second cylindrical mirror 5 to the second laser beam. A third adjustment structure 8 is provided between the radial end face of the second mounting base 3 and the first mounting base 2 for adjusting the perpendicularity of the second cylindrical mirror 5 to the first cylindrical mirror 4.

[0043] The axial end face of the first mounting base 2 can be understood as the end face along the axial direction of the cross laser module, where the axial direction is the length direction of the cross laser module, and can also be regarded as the axial direction of the lens barrel 1. The radial end face of the first mounting base 2 can be understood as the end face along the radial direction of the cross laser module, and the radial end face is perpendicular to the axial end face.

[0044] In use, the cross laser module provided in the above embodiment emits a first laser beam to the first cylindrical mirror 4 and a second laser beam to the second cylindrical mirror 5. The first cylindrical mirror 4 is perpendicular to the second cylindrical mirror 5. When it is necessary to adjust the straightness of the laser lines generated by the first cylindrical mirror 4 and the second cylindrical mirror 5, as well as the perpendicularity between the two laser lines, the perpendicularity between the first cylindrical mirror 4 and the first laser beam can first be adjusted by the first adjustment structure 6; then the perpendicularity between the second cylindrical mirror 5 and the second laser beam can be adjusted by the second adjustment structure 7; and finally, the perpendicularity between the second cylindrical mirror 5 and the first cylindrical mirror 4 can be adjusted by the third adjustment structure 8.

[0045] Since the second adjustment structure 7 and the third adjustment structure 8 act on the axial end face and radial end face of the first mounting base 2 respectively, the two adjustment structures can independently adjust the angle between the second cylindrical mirror 5 and the second laser beam, as well as the angle between the second cylindrical mirror 5 and the first cylindrical mirror 4. The operation is simple and can achieve more precise adjustment of the position of the second cylindrical mirror 5, which is beneficial to ensure the straightness of the laser line finally generated by the second cylindrical mirror 5 and the perpendicularity between the laser lines generated by the two cylindrical mirrors.

[0046] In alternative implementations, such as Figure 1 and Figure 2 As shown, the first mounting base 2 includes a first connecting rib 21, a first mounting plate 22, and a first mounting block 23; one side of the first mounting plate 22 is connected to the first mounting block 23, and the first cylindrical mirror 4 is mounted on the first mounting block 23; the other side of the first mounting plate 22 is connected to the axial end face of the mirror barrel 1 through the first connecting rib 21, and the first connecting rib 21 is perpendicular to the first cylindrical mirror 4; the first adjustment structure 6 is disposed between the axial end face of the mirror barrel 1 and the first mounting plate 22.

[0047] In use, the first mounting plate 22 can be swayed to either side of the first connecting rib 21 by the first adjustment structure 6, with the first connecting rib 21 as the fulcrum. Since the extension direction of the first connecting rib 21 is perpendicular to the first cylindrical mirror 4, the perpendicularity between the first cylindrical mirror 4 and the first laser beam can be adjusted to ensure that the first cylindrical mirror 4 can receive the first laser beam from the mirror tube 1 at the best angle and generate a straight and stable laser line.

[0048] Through the above structural design, the first mounting base 2 not only has good structural rigidity and stability, but also can flexibly adjust the installation angle of the first cylindrical mirror 4 through the first adjustment structure 6, which helps to improve the overall assembly accuracy of the laser module and the straightness of the laser line, and meet the application requirements of high-precision laser positioning.

[0049] The material of the first connecting rib 21 can be plastic or other structures that can produce a certain elastic deformation.

[0050] In alternative implementations, such as Figure 3 and Figure 4 As shown, the first adjustment structure 6 includes a first clamping member 61 and a second clamping member 62, both of which are threadedly engaged with the first mounting plate 22. The first clamping member 61 and the second clamping member 62 are respectively disposed on both sides of the first connecting rib 21.

[0051] During adjustment, different forces can be applied to the portions of the first mounting plate 22 located on either side of the first connecting rib 21 by tightening or loosening the first clamping member 61 and the second clamping member 62. For example, when a clamping member on one side is tightened, it pushes that portion of the first mounting plate 22 away from the end face of the lens barrel 1, causing the first mounting plate 22 to swing slightly around the first connecting rib 21. Since the first cylindrical mirror 4 is mounted on the first mounting block 23, the swing of the first mounting plate 22 will directly cause a change in the tilt angle of the first cylindrical mirror 4. In specific operation, the adjustment process of the first clamping member 61 and the second clamping member 62 can be repeated until the ideal laser line output effect is achieved.

[0052] By adjusting the above methods, the perpendicularity of the first cylindrical mirror 4 to the incident direction of the first laser beam can be precisely adjusted, thereby optimizing the generation effect of the laser line and ensuring the straightness and stability of the laser line.

[0053] The first clamping member 61 and the second clamping member 62 can be fastened with set screws, screws, adjusting bolts, or other fastening elements with threaded adjustment function. During assembly, the first clamping member 61 and the second clamping member 62 pass through the threaded holes on the first mounting plate 22 and abut against the axial end face of the lens barrel 1.

[0054] like Figure 3 As shown, the arrangement direction of the first clamping member 61 and the second clamping member 62 is parallel to the axial direction of the first cylindrical mirror 4. Specifically, the first clamping member 61 and the second clamping member 62 can be located at both ends of the first cylindrical mirror 4, respectively.

[0055] In an optional embodiment, the second mounting base 3 is connected to the first mounting plate 22, and the second mounting base 3 is located to the side of the first mounting block 23 and spaced apart from the first mounting block 23.

[0056] The aforementioned spacing ensures that the second mounting base 3 does not interfere with the first mounting block 23 in terms of spatial layout, while also ensuring a reasonable positional relationship between the second cylindrical mirror 5 and the first cylindrical mirror 4, which facilitates the setting of the third adjustment structure 8.

[0057] In an optional embodiment, a second adjustment structure 7 is provided between the second mounting base 3 and the axial end face of the first mounting plate 22, thereby adjusting the distance between a partial position of the second mounting base 3 and the first mounting plate 22. A third adjustment structure 8 is provided between the second mounting base 3 and the first mounting block 23, thereby adjusting the distance between a partial position of the second mounting base 3 and the first mounting block 23.

[0058] In an optional embodiment, the second mounting base 3 includes a second connecting rib 31, a second mounting plate 32, and a second mounting block 33; one side of the second mounting plate 32 is connected to the second mounting block 33, and the second cylindrical mirror 5 is mounted on the second mounting block 33; the other side of the second mounting plate 32, near the first mounting block 23, is connected to the axial end face of the first mounting plate 22 via the second connecting rib 31, and the second connecting rib 31 is perpendicular to the second cylindrical mirror 5; the second adjustment structure 7 is disposed between the axial end face of the first mounting plate 22 and the end of the second mounting plate 32 away from the first mounting block 23, and the third adjustment structure 8 is disposed between the second mounting block 33 and the first mounting block 23.

[0059] In use, the second mounting plate 32 can be forced to swing around the second connecting rib 31 using the second adjustment structure 7, adjusting the tilt angle of the second mounting plate 32 relative to the first mounting plate 22. This allows for fine-tuning of the perpendicularity between the second cylindrical mirror 5 and the second laser beam, ensuring that the second cylindrical mirror 5 receives the second laser beam from the lens barrel 1 at the optimal angle. Alternatively, the third adjustment structure 8 can force the second mounting block 33 to rotate the second mounting plate 32 at the second connecting rib 31, adjusting the position of the second mounting block 33 relative to the first mounting block 23, thereby adjusting the perpendicularity between the second cylindrical mirror 5 and the first cylindrical mirror 4.

[0060] Through the above structural design, the second mounting base 3 not only has good structural stability and load-bearing capacity, but also can achieve multi-dimensional adjustment of the installation angle of the second cylindrical mirror 5 through the second adjustment structure 7 and the third adjustment structure 8, which helps to improve the overall assembly accuracy of the laser module and the straightness of the laser line, and meet the application requirements of high-precision laser positioning and measurement.

[0061] The material of the second connecting rib 31 mentioned above can be plastic or other structures that can produce a certain elastic deformation.

[0062] In alternative implementations, such as Figure 5As shown, the second adjustment structure 7 includes a third clamping member 71 that is threadedly engaged with the second mounting plate 32. The third clamping member 71 is located on the side of the second mounting block 33 opposite to the first mounting block 23.

[0063] During the adjustment process, the perpendicularity between the second cylindrical mirror 5 and the second laser beam can be adjusted by rotating the third clamping member 71 to apply a force away from the first mounting block 23 to the end of the second mounting plate 32.

[0064] The third clamping element 71 can be a set screw, screw, adjusting bolt, or other fastening element with thread adjustment function. During assembly, the third clamping element 71 passes through the threaded hole on the second mounting plate 32 and abuts against the axial end face of the first mounting plate 22.

[0065] In an optional embodiment, the third adjustment structure 8 includes a fourth clamping member 81 and a fifth clamping member 82, both of which are threadedly engaged with the second mounting block 33. The fourth clamping member 81 and the fifth clamping member 82 are respectively disposed on both sides of the second cylindrical mirror 5.

[0066] In use, the fourth clamping member 81 and the fifth clamping member 82 apply adjustment force to the second mounting block 33 from both sides of the second cylindrical mirror 5. By tightening or loosening the fourth clamping member 81 and the fifth clamping member 82 respectively, the angle of the second cylindrical mirror 5 can be finely adjusted, thereby precisely adjusting its perpendicularity to the first cylindrical mirror 4.

[0067] In an optional embodiment, the distribution direction of the fourth clamping member 81 and the fifth clamping member 82 is parallel to the axial direction of the first cylindrical mirror 4, so as to avoid unnecessary interference to the laser line due to the misalignment of the fourth clamping member 81 and the fifth clamping member 82 during the adjustment process.

[0068] In an optional embodiment, the first clamping member 61, the second clamping member 62, the third clamping member 71, the fourth clamping member 81 and the fifth clamping member 82 are all made of set screws, and the set screws are made of M2.5 high-strength stainless steel.

[0069] In an optional embodiment, the lens tube 1 can adopt an existing structure, which contains a laser and a catadioptric mirror assembly; the laser uses a high-precision laser source; the catadioptric mirror assembly includes two mirrors, one of which is a 45-degree semi-transparent and semi-reflective mirror, and the other is a 45-degree total reflection mirror, so that the light emitted by the laser can be split into two parallel laser beams, solving the laser diffraction problem and improving the quality of the laser line spot.

[0070] The second aspect of this utility model provides a laser line projector, which includes the aforementioned cross laser module.

[0071] The laser line projector provided in the second aspect of this utility model has the cross laser module provided in the first aspect of this utility model, and thus has all the beneficial effects of the cross laser module provided in the first aspect of this utility model.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
