[0036] Embodiment:

[0037] Please refer to Figures 1 to 4 , in a preferred embodiment of the present utility model, the angle-adjustable optical lens fixing device includes a lens adjusting assembly 1 and a lens barrel assembly 2 which are rotatably connected, and arc-shaped rotating surfaces 111 and mounting surfaces 211 that are concavo-convexly matched are respectively provided in the lens adjusting assembly 1 and the lens barrel assembly 2, so as to realize the adjustment of the pitching angle of the optical lens 11 by rotating the lens adjusting assembly 1 along the mounting surface 211.

[0038] Specifically, as shown in Figure 1 and Figure 3 , both the lens adjusting assembly 1 and the lens barrel assembly 2 are hollow along the axis and serve as an optical path channel. One end of the lens adjusting assembly 1 is mounted with the optical lens 11, and the other end has a convex arc-shaped rotating surface 111. One end of the lens barrel assembly 2 has a concave arc-shaped mounting surface 211 adapted to the rotating surface 111 of the lens adjusting assembly 1. The rotating surface 111 of the lens adjusting assembly 1 contacts the mounting surface 211 of the lens barrel assembly 2 and can rotate along the mounting surface 211. Furthermore, a good sealing effect is achieved by the way of the concavo-convex arc surfaces being embedded, preventing air leakage from the rotating surface, and effectively preventing dust from entering during actual production applications.

[0039] Meanwhile, the lens adjusting assembly 1 is rotatably connected to the lens barrel assembly 2 through a connecting member 4. One end of the connecting member 4 is fixedly connected to the lens barrel assembly 2, and the other end is hinged to the lens adjusting assembly 1. Preferably, connecting members 4 are respectively arranged on both axial sides of the lens adjusting assembly 1 and symmetrically arranged at both ends in the direction perpendicular to the rotating surface 111. It can be understood that they are also arranged on both sides of the lens barrel assembly 2 in the direction perpendicular to the mounting surface 211. As shown in Figure 2 , the connecting member 4 is set as a triangular structure, one end of which is connected to the lens barrel assembly 2 through multiple points, and the other end is singly hinged to the lens adjusting assembly 1.

[0040] Preferably, a guiding assembly is also provided corresponding to the rotation of the lens adjusting assembly 1 to guide the rotation path of the lens adjusting assembly 1.

[0041] In a specific embodiment of the present invention, Figure 2 As shown in the figure, the guide assembly includes an arcuate guide groove 41 and a guide pin 12; wherein the arcuate guide groove 41 is arranged on the connecting member 4, one end of the guide pin 12 is connected to the lens adjustment assembly 1, and the other end is slidably connected to the arcuate guide groove 41, and can slide along the extension direction of the arcuate guide groove 41 to facilitate the rotation of the lens adjustment assembly 1, and the pitch angle range of the lens adjustment assembly 1 is controlled by the extension length of the arcuate guide groove 41.

[0042] Preferably, the arc-shaped guide groove 41 is offset on the upper side or the lower side of the connector 4, and the installation direction of the connector 4 and the lens adjustment assembly 1 is determined by one-way fool-proofing to avoid unilateral air leakage due to installation errors.

[0043] In another specific embodiment of the utility model, the guide assembly includes an arcuate guide groove and a guide block; wherein, the arcuate guide groove is arranged on the lens adjustment assembly 1, and the guide block is connected to the connecting member 4, and the guide block is placed in the arcuate guide groove and can slide along the extension direction of the arcuate guide groove to facilitate the rotation of the lens adjustment assembly 1 and control the pitch angle range of the lens adjustment assembly 1.

[0044] Those skilled in the art can understand that, in the above, the rotating surface 111 and the mounting surface 211 are arranged in the vertical direction as an example, and the lens adjustment assembly 1 can adjust the pitch angle. The present application is not limited thereto, and the rotating surface 111 and the mounting surface 211 can be arranged in other directions, such as in the horizontal direction, to adjust the horizontal angle, and in other directions, to adjust the angles in other directions.

[0045] Furthermore, the lens barrel assembly 2 in the preferred embodiment includes a lens barrel connecting ring 21 and a rotating base 22. The rotating base 22 extends into the lens barrel connecting ring 21 and can rotate along the circumference of the lens barrel connecting ring 21.

[0046] Specifically, one end of the lens barrel ring 21 is installed in the inner hole of the lens frame assembly 3, and the rotating base 22 is arranged on the side of the lens barrel ring 21 away from the lens frame assembly 3, and one end of the rotating base 22 extends into the lens barrel ring 21, and a second top screw 23 is arranged between the rotating base 22 and the lens barrel ring 21, and one end of the second top screw 23 passes through the lens barrel ring 21 and abuts against the outer peripheral wall of the rotating base 22, so as to control the circumferential rotation of the rotating base 22 relative to the lens barrel ring 21 by screwing the second top screw 23.

[0047] It can be understood that the mirror frame assembly 3 is an existing mirror frame assembly, and it is fixed in the optical path system workbench, and its specific structure is not described here.

[0048] Accordingly, the lens adjustment assembly 1 is disposed at one end of the rotary base 22 facing away from the lens barrel adapter 21. An inwardly concave arc-shaped mounting surface 211 is provided on the side of the rotary base 22 facing away from the lens barrel adapter 21. The rotary base 22 is connected to the lens adjustment assembly 1 through a connecting member 4.

[0049] During actual use, slightly loosen the second set screw 23, and then the rotary base 22 can be rotated. After it is in place, lock the second set screw 23 again. Thus, the rotary base 22 can rotate circumferentially along the lens barrel adapter 21, and the lens adjustment assembly 1 can rotate along the mounting surface 211 of the rotary base 22, so that the optical lens 11 mounted in the lens adjustment assembly 1 can be rotated and the angle can be controlled in multiple dimensions.

[0050] Furthermore, as Figure 4 shown in, the lens adjustment assembly 1 includes a rotary block 13 and a lens holder 14. A rotary surface 111 is provided on one side of the rotary block 13, and a mounting groove is provided on the other side. The lens holder 14 is embedded in the mounting groove, and the lens holder 14 can rotate along the axis of the mounting groove. At the same time, at least one mounting hole communicating with the mounting groove is provided on the side wall of the mounting groove, and a first set screw 17 is provided in the mounting hole. One end of the first set screw 17 passes through the mounting hole and presses against the lens holder 14 to fix the lens holder 14 in the mounting groove and control the rotation of the lens holder 14.

[0051] Accordingly, an opening is provided at one end of the lens holder 14 facing away from the rotary surface 111. The optical lens 11 is placed in the lens holder 14 through the opening, and the optical lens 11 is fixed in the lens holder 14 through a retaining ring 15 and a lock ring 16.

[0052] During actual use, loosen the first set screw 17, and the lens holder 14 can rotate axially. After it is in place, lock the first set screw 17 again. Thus, through the circumferential rotation of the lens holder 14, the adjustment dimension of the optical lens 11 is further increased.

[0053] Preferably, since the lens adjustment assembly 1 may be tilted downward after installation and adjustment, to prevent the lens holder 14 from falling off when the first set screw 17 is loosened to adjust the angle of the lens holder 14, it is preferred to provide an arc groove on the outer peripheral wall of the lens holder 14. The first set screw 17 is a round head set screw, and one end of the first set screw 17 can be inserted into the arc groove, so that after the first set screw 17 is loosened, the end of the first set screw 17 is still within the arc groove to limit the lens holder 14 and prevent the lens holder 14 from falling off. The lens adjustment assembly 1 in the present invention takes its own hinge point as the rotation point and its own arc surface as the rotation surface 111, and is fixed to the rotary base 22 through the connecting member 4 and is adjustable; the rotary base 22 is rotatably adjustable relative to the lens barrel adapter ring 21; the lens holder 14 is rotatably adjustable relative to the lens adjustment assembly 1, realizing the adjustment of the optical lens 11 in multiple directions and at multiple angles such as the pitch rotation angle and the horizontal rotation angle.

[0054] The angle-adjustable optical lens fixing device in the present invention has a compact and small structure, is convenient to install, has high stability, realizes three-stage adjustment of the lens, can quickly adjust the angle required by the process, and ensures the stability of optical use, and has good application prospects and popularization value.

[0055] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
