Technical Field

[0001] The present invention relates to a laser device, and particularly to an angle adjustment mechanism. Background Art

[0002] The fields that require angle adjustment are very extensive, such as the angle adjustment of lenses and the angle adjustment of laser levels. However, the current adjustment method of laser levels is relatively cumbersome. It requires the joint adjustment and cooperation of multiple screws to achieve angle adjustment, which has relatively high requirements for operators and requires long-term practice. Summary of the Invention

[0003] Object of the Invention: The object of the present invention is to provide an angle adjustment mechanism to remove complex structures and simplify adjustment steps.

[0004] Technical Solution: The angle adjustment mechanism described in the present invention includes a base with a lens mounting hole, and is characterized in that a horizontal adjustment component and a vertical adjustment component are provided on the base. The horizontal adjustment component realizes the horizontal angle adjustment of the lens by changing the height difference between the two horizontal ends of the lens; the vertical adjustment component realizes the angle adjustment of the lens in the vertical direction by changing the height difference between the two ends where the lens is provided.

[0005] Further, the vertical adjustment component includes an annular ring, a first adjustment screw rod, and a first elastic member nested on the first adjustment screw rod. The annular ring is detachably connected to the lens. The first adjustment screw rod passes through the elastic member and the annular ring and is screwed to the base. The horizontal adjustment component includes a support bar, a second elastic member, and a second adjustment screw rod. The second adjustment screw rod passes through the second elastic member and the support bar and is screwed to the base. The support bar realizes the horizontal angle adjustment of the annular ring by changing the height difference between its two horizontal ends.

[0006] Further, one of the first elastic members on the first adjustment screw rod is located between the annular ring and the base, and the other first elastic member is located between the first adjustment screw rod and the annular ring.

[0007] Further, one of the second elastic members on the second adjustment screw rod is located between the support bar and the base, and the other second elastic member is located between the second adjustment screw rod and the support bar.

Description of the Drawings

[0012] Figure 1 is a schematic diagram of the overall structure of the angle adjustment mechanism;

[0013] Figure 2 is an exploded view of the angle adjustment mechanism. Detailed Embodiment

[0014] As Figure 1 shown, an angle adjustment mechanism includes a base 1 with a lens mounting hole. A lateral adjustment assembly 2 and a vertical adjustment assembly 3 are provided on the base 1. The lateral adjustment assembly 2 realizes the lateral angle adjustment of the lens by changing the height difference between the lateral ends of the lens; the vertical adjustment assembly 3 realizes the angle adjustment of the lens in the vertical direction by changing the height difference between the vertical ends of the lens.

[0015] As Figure 1 and Figure 2 shown, the lateral adjustment assembly 3 includes an annular ring 31, an adjusting screw one 32, a pressing screw one 33, and an elastic member one 33 nested on the adjusting screw one 32 and the pressing screw 33. The annular ring 31 is detachably connected to the lens. The adjusting screw one 32 penetrates through the annular ring 31 and the elastic member 34 and is screwed to the base 1. Among them, the elastic member one 34 on the adjusting screw one 32 is located between the annular ring 31 and the base 1, and the other elastic member one 34 is located between the pressing screw one 33 and the annular ring 31.

[0016] The vertical adjustment assembly 2 includes a support bar 21, an elastic member two 22, a pressing screw two 24, and an adjusting screw two 23. The pressing screw two 24 penetrates through the elastic member two 22 and the support bar 21 and is screwed to the base 1. The support bar 21 realizes the lateral angle adjustment of the annular ring 31 by changing the height difference between its vertical ends; among them, the elastic member two 22 on the adjusting screw two 23 is located between the support bar 21 and the base 1, and the other elastic member two 22 is located between the pressing screw two 24 and the support bar 21.

[0017] An arc-shaped block two 7 is provided on the base 1, and the support bar 21 is provided with an arc-shaped groove two 8 for fitting with the surface of the arc-shaped block two 7; the pressing screw two 24 sequentially penetrates through the elastic member two 22, the support bar 21, and the arc-shaped block two 7 from top to bottom, and is screwed to the base 1. The support bar 21 is provided with a straight groove two 9 in the vertical direction of the adjusting screw two 23; when the lens is adjusted in the vertical direction angle, the support bar 21 slides along the arc direction of the arc-shaped block two 7.

[0018] The annular ring 31 is arranged in contact with the support bar 21, and the pressing screw one 33 sequentially penetrates through the elastic member one 34 and the annular ring 31 from top to bottom, and is screwed to the support bar 21.

[0019] An arc-shaped block one 4 is provided on the support bar 21, and the annular ring 31 is provided with an arc-shaped groove for fitting with the arc-shaped block one 4. The annular ring 31 is provided with a straight groove one 6 in the horizontal and straight direction of the adjusting screw one 32. When the lens is adjusted in the horizontal direction angle, the annular ring 31 slides along the arc direction of the arc-shaped block one 4.

[0020] Working process: Rotate the adjusting screw one 32, and the elastic member one 34 between the annular ring 31 and the base 1 undergoes elastic recovery or compression. The elastic member one 34 pushes the annular ring 31 upward to move or the elastic member one 34 is compressed downward by the screw. Therefore, the annular ring 31 is inclined in the horizontal direction, that is, a height difference is generated at both ends of the annular ring 31 in the horizontal direction. At the same time, due to the inclination of the annular ring 31 in the horizontal direction, on the side where the annular ring 31 contacts the arc-shaped block one 4, the annular ring 31 realizes the angle adjustment of the annular ring 31 by sliding along the straight groove one 6 through the pressing screw one 33 and the sliding of its arc-shaped groove along the surface of the arc-shaped block one 4, and the angle adjustment in this arc way is smoother and more controllable.

[0021] Rotate the adjusting screw two 23, and the elastic member one 22 between the support bar 21 and the base 1 undergoes elastic recovery or compression. The elastic member two 22 pushes the support bar 21 upward to move or the elastic member one 22 is compressed downward by the screw. Therefore, the support bar 21 is inclined horizontally, that is, a height difference is generated at both ends of the support bar 21 in the horizontal direction.

[0022] At the same time, due to the horizontal inclination of the support bar 21, the support bar 21 drives the annular ring 31 to incline vertically. At the end where the support bar 21 contacts the arc-shaped block two 7, the support bar 21 realizes the angle adjustment of the support bar 21 by sliding along the straight groove two 9 through the pressing screw two 24 and the sliding of its arc-shaped groove along the surface of the arc-shaped block two 7. Since the support bar 21 drives the annular ring 31 to incline vertically, then when the support bar 21 realizes its own angle adjustment, it also drives the vertical angle adjustment of the annular ring 31, and finally realizes the vertical angle adjustment of the lens, and the angle adjustment in this arc way is smoother and more controllable.

[0023] Therefore, the angle adjustment of the lens in the vertical direction and the horizontal angle adjustment can be achieved only by rotating two adjusting screws, which simplifies the adjustment method, reduces the part matching, and lowers the operation difficulty.

[0024] Specifically, the base 1 can be installed with a lens on all surfaces other than the surface used for installation with the fixing frame, and a vertical adjustment component 2 and a horizontal adjustment component 3 are installed on the corresponding surfaces to adjust the angle of the lens.
