[0035] Cylindrical mirrors are commonly used in optical devices such as optical experimental instruments and optical lenses. Because the yaw angle of a cylindrical mirror can affect light focus, spot shape, light intensity distribution, and image quality, it is necessary to adjust the yaw angle of the cylindrical mirror in some applications. However, in existing technologies, cylindrical mirrors are typically installed directly within the lens barrel, requiring disassembly and assembly to adjust the yaw angle, making adjustment of the yaw angle difficult.

[0036] Therefore, the embodiment of the present application provides a cylindrical mirror angle adjustment mechanism, which can facilitate the rapid and effective adjustment of the yaw angle of the cylindrical mirror, and can improve the convenience, adjustment accuracy and adjustment stability of the yaw angle of the cylindrical mirror.

[0037] The following describes the specific implementation of this application in detail with reference to specific embodiments:

[0038] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Some embodiments of the present application provide a cylindrical mirror angle adjustment mechanism, including a lens barrel assembly 10, a cylindrical mirror bracket 20, and an adjustment structure 30. The lens barrel assembly 10 includes a lens barrel body 11 and a first pressure ring 12 connected to the end side of the lens barrel body 11; the cylindrical mirror bracket 20 is provided with at least one, and is arranged in the space enclosed by the first pressure ring 12 and the lens barrel body 11; the adjustment structure 30 is arranged corresponding to the cylindrical mirror bracket 20, and the adjustment structure 30 is connected to the circumferential side of the cylindrical mirror bracket 20 and keeps synchronous rotation with the cylindrical mirror bracket 20; the barrel wall of the lens barrel assembly 10 is penetrated by an adjustment groove 13 arranged corresponding to the adjustment structure 30, the adjustment groove 13 extends along the circumference of the lens barrel assembly 10, and the adjustment structure 30 is slidably connected to the adjustment groove 13.

[0039] It should be noted that each cylindrical mirror bracket 20 can be used to install at least one cylindrical mirror 40, wherein the cylindrical mirror bracket 20 can limit the cylindrical mirror 40 installed on itself based on its own slot design, etc., and can also limit the cylindrical mirror 40 installed on itself based on other components (such as adjacent cylindrical mirror brackets 20, pressure rings, etc.), thereby achieving stable installation of the cylindrical mirror 40.

[0040] The lens barrel body 11 is cylindrical. At least one cylindrical mirror holder 20 can be installed in the lens barrel body 11. When the cylindrical mirror holder 20 is installed in the lens barrel body 11, the cylindrical mirror holder 20 can rotate circumferentially relative to the lens barrel body 11 (i.e., it has rotational freedom) and can maintain a stable axial position relative to the lens barrel body 11 (i.e., it does not substantially move axially). The stable axial position of the cylindrical mirror holder 20 relative to the lens barrel body 11 can be achieved based on the constraints of the lens barrel body 11's own structure (e.g., a stepped structure, slot positions, etc.), the matching constraints between the adjustment structure 30 and the adjustment slot 13, or the constraints of other structures (e.g., a pressure ring, etc.), etc.

[0041] The first pressing ring 12 is connected to one end side of the lens barrel body 11. The first pressing ring 12 can prevent the cylindrical lens holder 20 in the lens barrel body 11 from falling out of the lens barrel body 11. The first pressing ring 12 and the lens barrel body 11 can be connected in a detachable manner (such as screw connection, snap connection, etc.) or in a fixed manner (such as welding, bonding, etc.).

[0042] The adjustment structure 30 is arranged in a one-to-one correspondence with the cylindrical mirror bracket 20. The adjustment structure 30 can be directly connected to the circumferential side of the cylindrical mirror bracket 20, or it can be indirectly connected to the cylindrical mirror bracket 20 by other components (such as the second pressure ring 50 below) and located on the circumferential side of the cylindrical mirror bracket 20. The adjustment structure 30 can be connected and fixed by a detachable connection method (such as screw connection, snap connection, etc.), or by a fixed connection method (such as welding, bonding, etc.). Based on the connection between the adjustment structure 30 and the cylindrical mirror bracket 20, the adjustment structure 30 can rotate synchronously with the cylindrical mirror bracket 20, that is, the circumferential rotation of the adjustment structure 30 can drive the circumferential rotation of the cylindrical mirror bracket 20 and its cylindrical mirror 40. Among them, the shape and size of the adjustment structure 30 can be set as needed, for example, the adjustment structure 30 can be block-shaped, etc. Among them, in the case where there are multiple adjustment structures 30, the structure, shape, and size of each adjustment structure 30 can be set the same or different.

[0043] An adjustment groove 13 is provided on the wall of the lens barrel assembly 10. The adjustment groove 13 extends along the circumference of the lens barrel assembly 10 and penetrates the wall of the lens barrel assembly 10 along its depth. Depending on the layout requirements of the adjustment groove 13, the adjustment groove 13 can be provided on the wall of the lens barrel body 11 or on the wall of the first pressing ring 12 (i.e., the portion of the first pressing ring 12 corresponding to the circumference of the lens barrel assembly 10).

[0044] The adjustment slots 13 are arranged in a one-to-one correspondence with the adjustment structures 30, and the adjustment structures 30 are slidably connected to the adjustment slots 13. Based on this, the adjustment structure 30 can be exposed outside the barrel assembly 10. The operator can drive the adjustment structure 30 to slide along the adjustment slots 13 to drive the cylindrical mirror holder 20 and its cylindrical mirror 40 to rotate circumferentially within the travel range constrained by the adjustment slots 13, thereby conveniently and quickly adjusting the yaw angle of the cylindrical mirror 40.

[0045] For example, Figure 4 、 Figure 5 、 Figure 6 As shown, in a specific example of a cylindrical mirror angle adjustment mechanism, three cylindrical mirror holders 20 are provided in the space enclosed by the first pressure ring 12 and the lens barrel body 11. The three cylindrical mirror holders 20 are respectively a first cylindrical mirror holder 20a, a second cylindrical mirror holder 20b, and a third cylindrical mirror holder 20c. The first cylindrical mirror holder 20a, the second cylindrical mirror holder 20b, and the third cylindrical mirror holder 20c are arranged in sequence in a direction away from the first pressure ring 12. A first adjustment structure 30a is provided corresponding to the first cylindrical mirror holder 20a and is directly connected to the circumferential side of the first cylindrical mirror holder 20a. By sliding the first adjustment structure 30a along the corresponding adjustment groove 13, the first cylindrical mirror holder 20a and its first cylindrical mirror 40a can be driven to rotate circumferentially via the first adjustment structure 30a, thereby conveniently and quickly adjusting the yaw angle of the first cylindrical mirror 40a. The second adjustment structure 30b is provided in correspondence with the second cylindrical mirror holder 20b and is directly connected to the circumference of the second cylindrical mirror holder 20b. By sliding the second adjustment structure 30b along the corresponding adjustment slot 13, the second adjustment structure 30b can drive the second cylindrical mirror holder 20b and the second cylindrical mirror 40b to rotate circumferentially, thereby conveniently and quickly adjusting the yaw angle of the second cylindrical mirror 40b. The third adjustment structure 30c is provided in correspondence with the third cylindrical mirror holder 20c. The third adjustment structure 30c is indirectly connected to the third cylindrical mirror holder 20c via other components and is located on the circumference of the third cylindrical mirror holder 20c. By sliding the third adjustment structure 30c along the corresponding adjustment slot 13, the third adjustment structure 30c can drive the third cylindrical mirror holder 20c and the third cylindrical mirror 40c to rotate circumferentially, thereby conveniently and quickly adjusting the yaw angle of the third cylindrical mirror 40c.

[0046] In summary, the cylindrical mirror angle adjustment mechanism provided in the embodiment of the present application can guide and constrain the circumferential movement path and movement stroke of the adjustment structure 30 along the lens barrel assembly 10 through the adjustment groove 13, and can drive the adjustment structure 30 to slide along the adjustment groove 13 so as to drive the cylindrical mirror bracket 20 and the cylindrical mirror 40 in the lens barrel body 11 to rotate circumferentially within the adjustable range constrained by the adjustment groove 13, thereby conveniently, quickly, reliably and effectively adjusting the swing angle of the cylindrical mirror 40, and there is no need to disassemble the cylindrical mirror bracket 20 into the space enclosed by the first pressure ring 12 and the lens barrel body 11 to adjust the swing angle of the cylindrical mirror 40, which can improve the adjustment convenience, adjustment accuracy and adjustment stability of the swing angle of the cylindrical mirror 40.

[0047] In addition, when the yaw angle of the cylindrical mirror 40 is adjusted, the adjustment structure 30 can be fixed to the barrel wall of the lens barrel assembly 10 by means of, but not limited to, screw locking, adhesive fixing, etc., to stabilize the position of the adjustment structure 30 in the adjustment slot 13, thereby ensuring that the yaw angle of the cylindrical mirror 40 remains stable.

[0048] See also Figure 1 、 Figure 2 、 Figure 4 In some embodiments of the present application, the adjustment structure 30 includes a connecting portion 31 and a sliding portion 32 that are bent and connected in sequence. The connecting portion 31 is connected to the peripheral side of the cylindrical mirror bracket 20, and the sliding portion 32 is slidably arranged in the adjustment groove 13.

[0049] It should be noted that the connecting portion 31 can be directly connected to the peripheral side of the cylindrical mirror bracket 20. For example, the connecting portion 31 of the first adjustment structure 30a can be directly connected to the peripheral side of the first cylindrical mirror bracket 20a (eg Figure 6 As shown), for example, the connecting portion 31 of the second adjustment structure 30b can be directly connected to the peripheral side of the second cylindrical mirror bracket 20b (as shown Figure 5 As shown). The connecting portion 31 can also be indirectly connected to the cylindrical mirror bracket 20 through other components and located on the peripheral side of the cylindrical mirror bracket 20. For example, the connecting portion 31 of the third adjustment structure 30c can be directly connected to the peripheral side of the second pressure ring 50 to indirectly connect to the cylindrical mirror bracket 20 (as shown). Figure 4 The connection method used by the connection portion 31 can be a detachable connection method (such as screw connection, snap connection, etc.) or a fixed connection method (such as welding, bonding, etc.).

[0050] The sliding portion 32 is connected to the side of the connecting portion 31 near the adjustment slot 13. The sliding portion 32 and the connecting portion 31 can be connected as a single piece or as separate pieces. The sliding portion 32 and the connecting portion 31 are bent, i.e., they are arranged at an angle. The angle between the sliding portion 32 and the connecting portion 31 can be set as needed. For example, the angle between the sliding portion 32 and the connecting portion 31 can be a right angle (i.e., the sliding portion 32 is perpendicular to the connecting portion 31). The sliding portion 32 is inserted into the adjustment slot 13 and can slide along the adjustment slot 13 under the action of an external force. The adjustment slot 13 can guide and constrain the sliding path and sliding travel of the sliding portion 32.

[0051] By adopting the above solution, the adjustment structure 30 can be conveniently and reliably connected to the cylindrical mirror holder 20 via the connection portion 31, and can also be inserted into the adjustment slot 13 via the sliding portion 32, so that the yaw angle of the cylindrical mirror 40 can be quickly adjusted by driving the sliding portion 32 to slide along the adjustment slot 13. Based on this, the structural design of the adjustment structure 30 can be simplified and optimized, the structural reliability and compactness of the adjustment structure 30 can be improved, the convenience, reliability and stability of the connection between the adjustment structure 30 and the cylindrical mirror holder 20 can be improved, the convenience and reliability of the matching between the adjustment structure 30 and the adjustment slot 13 can be improved, the yaw angle of the cylindrical mirror 40 can be quickly, reliably and effectively adjusted via the sliding portion 32, and the convenience, accuracy and stability of adjusting the yaw angle of the cylindrical mirror 40 can be improved.

[0052] See also Figure 1 、 Figure 2 、 Figure 4 In some embodiments of the present application, the adjustment structure 30 further includes a stabilizing portion 33 , which is bent and connected to a side of the sliding portion 32 away from the connecting portion 31 , and the stabilizing portion 33 abuts against the outer cylindrical surface of the lens barrel assembly 10 .

[0053] It should be noted that, when the adjustment structure 30 includes a connecting portion 31 and a sliding portion 32, the adjustment structure 30 also includes a stabilizing portion 33. The stabilizing portion 33 is connected to the side of the sliding portion 32 away from the connecting portion 31, that is, connected to the side of the sliding portion 32 that passes through the adjustment groove 13. The stabilizing portion 33 and the sliding portion 32 can be connected as a whole or as a separate body. The stabilizing portion 33 and the sliding portion 32 are bent and connected, that is, the stabilizing portion 33 and the sliding portion 32 are arranged at an angle. The angle between the stabilizing portion 33 and the sliding portion 32 can be set as needed, for example, the angle between the stabilizing portion 33 and the sliding portion 32 can be a right angle (that is, the stabilizing portion 33 is perpendicular to the sliding portion 32). The "bending direction of the stabilizing portion 33 relative to the sliding portion 32" and the "bending direction of the connecting portion 31 relative to the sliding portion 32" can be set oppositely or the same. The stabilizing portion 33 abuts against the outer surface of the lens barrel assembly 10 . When the sliding portion 32 slides along the adjustment groove 13 , the stabilizing portion 33 moves synchronously with the sliding portion 32 and maintains abutment against the outer surface of the lens barrel assembly 10 .

[0054] By adopting the above solution, the adjustment structure 30 can also be connected to the side of the sliding portion 32 away from the connecting portion 31 by bending the stabilizing portion 33, so that the adjustment structure 30 moves synchronously with the sliding portion 32 during the sliding process of the sliding portion 32 along the adjustment slot 13, and maintains abutment against the outer cylindrical surface of the lens barrel assembly 10. Based on this, the structural design of the adjustment structure 30 can be optimized, and the abutment between the stabilizing portion 33 and the outer cylindrical surface of the lens barrel assembly 10 can provide support for the sliding of the adjustment structure 30, thereby reducing the shaking and deviation of the adjustment structure 30 during the sliding process, thereby improving the sliding stability and smoothness of the adjustment structure 30 along the adjustment slot 13, improving the rotational stability and smoothness of the adjustment structure 30, the cylindrical mirror holder 20 and the cylindrical mirror 40 along the circumferential direction of the lens barrel assembly 10, and improving the adjustment accuracy and adjustment stability of the yaw angle of the cylindrical mirror 40.

[0055] Of course, in other embodiments, the adjustment structure 30 may include only the sliding portion 32 , or the adjustment structure 30 may include only the sliding portion 32 and the stabilizing portion 33 , or the adjustment structure 30 may adopt other structural designs.

[0056] See also Figure 1 、 Figure 2 、 Figure 4 In some embodiments of the present application, a fastening hole 331 is formed through the stabilizing portion 33 , and a fastener can be passed through the fastening hole 331 to lock the relative position of the adjustment structure 30 relative to the lens barrel assembly 10 .

[0057] It should be noted that the stabilizing portion 33 is provided with a fastening hole 331, which passes through the stabilizing portion 33 along the thickness direction of the stabilizing portion 33. The fastening hole 331 can be, but is not limited to, a circular hole, a rectangular hole, or the like.

[0058] By adopting the above scheme, the locking process of the adjustment structure 30 can be simple and quick based on the design of the fastening hole 331. Specifically, when the yaw angle of the cylindrical mirror 40 is adjusted, a fastener (such as a screw, a pin, etc.) can be inserted into the fastening hole 331 to lock the stabilizing portion 33 to the outer cylinder surface of the lens barrel assembly 10, thereby fixing the adjustment structure 30 to the cylinder wall of the lens barrel assembly 10. This can stabilize the position of the adjustment structure 30 in the adjustment slot 13 and ensure that the yaw angle of the cylindrical mirror 40 remains stable after adjustment. In particular, when the fastener is a detachable component (such as a screw), the relative position of the adjustment structure 30 relative to the lens barrel assembly 10 can be locked conveniently and quickly by tightening the fastener into the fastening hole 331. It is also possible to conveniently and quickly move the adjustment structure 30 and adjust the yaw angle of the cylindrical mirror 40 again by loosening the fastener, thereby facilitating maintenance and adjustment.

[0059] Of course, in other embodiments, when the adjustment of the yaw angle of the cylindrical mirror 40 is completed, other methods (such as bonding and fixing) can be used to fix the adjustment structure 30 to the barrel wall of the lens barrel assembly 10 to stabilize the position of the adjustment structure 30 in the adjustment slot 13, thereby ensuring that the yaw angle of the cylindrical mirror 40 remains stable.

[0060] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 In some embodiments of the present application, a plurality of cylindrical mirror supports 20 are provided, and each cylindrical mirror support 20 is sequentially arranged along the axial direction of the lens barrel assembly 10 .

[0061] For example, Figure 4 、 Figure 5 、 Figure 6 As shown, in a specific example of a cylindrical mirror angle adjustment mechanism, three cylindrical mirror brackets 20 are provided in the space enclosed by the first pressure ring 12 and the lens barrel body 11. The three cylindrical mirror brackets 20 are respectively a first cylindrical mirror bracket 20a, a second cylindrical mirror bracket 20b, and a third cylindrical mirror bracket 20c. The first cylindrical mirror bracket 20a, the second cylindrical mirror bracket 20b, and the third cylindrical mirror bracket 20c are arranged in sequence along the axial direction of the lens barrel assembly 10, and are arranged in sequence in the direction away from the first pressure ring 12.

[0062] By adopting the above solution, the cylindrical mirror angle adjustment mechanism can be configured by sequentially disposing multiple cylindrical mirror holders 20 along the axial direction of the lens barrel assembly 10, so as to facilitate adjustment of the deflection angle of each cylindrical mirror holder 20 and its cylindrical mirror 40. Based on this, it is beneficial to improve the comprehensive beam shaping and focusing capabilities of each cylindrical mirror 40, and it is beneficial to improve the comprehensive optical effects such as light focusing, spot shape, light intensity distribution, and imaging quality achieved by each cylindrical mirror 40, making the cylindrical mirror angle adjustment mechanism suitable for high-precision optical applications.

[0063] Of course, in other embodiments, the cylindrical mirror angle adjustment mechanism may be provided with only one cylindrical mirror bracket 20 in the space enclosed by the first pressure ring 12 and the lens barrel body 11 .

[0064] See also Figure 4 、 Figure 5 、 Figure 6 In some embodiments of the present application, among any two adjacent cylindrical mirror brackets 20 , the cylindrical mirror bracket 20 relatively close to the first pressure ring 12 is partially embedded in the cylindrical mirror bracket 20 relatively far away from the first pressure ring 12 .

[0065] It should be noted that when multiple cylindrical mirror brackets 20 are arranged in sequence along the axial direction of the lens barrel assembly 10, between any two adjacent cylindrical mirror brackets 20, the "cylindrical mirror bracket 20 relatively close to the first pressure ring 12" can be partially embedded in the "cylindrical mirror bracket 20 relatively far away from the first pressure ring 12", and the "cylindrical mirror bracket 20 relatively far away from the first pressure ring 12" can use a stepped structure or the like to limit the support of the "cylindrical mirror bracket 20 relatively close to the first pressure ring 12".

[0066] For example, Figure 4 、 Figure 5 、 Figure 6 As shown, in a specific example of a cylindrical mirror angle adjustment mechanism, a first cylindrical mirror holder 20a, which is relatively close to the first pressing ring 12, is partially embedded in a second cylindrical mirror holder 20b, which is relatively far away from the first pressing ring 12, and is axially limited and supported by the second cylindrical mirror holder 20b. The second cylindrical mirror holder 20b, which is relatively close to the first pressing ring 12, is partially embedded in a third cylindrical mirror holder 20c, which is relatively far away from the first pressing ring 12, and is axially limited and supported by the third cylindrical mirror holder 20c.

[0067] By adopting the above-mentioned scheme, based on the nested design of each cylindrical mirror bracket 20, the space between the cylindrical mirror brackets 20 can be efficiently utilized, so that two adjacent cylindrical mirror brackets 20 can limit and support each other, and the cylindrical mirrors 40 of two adjacent cylindrical mirror brackets 20 can be relatively close, thereby optimizing the layout of each cylindrical mirror bracket 20 and each cylindrical mirror 40, facilitating the optimization of the comprehensive optical effect achieved by each cylindrical mirror 40, compressing the volume and weight of the entire cylindrical mirror angle adjustment mechanism, and improving the structural compactness and structural stability of the entire cylindrical mirror angle adjustment mechanism.

[0068] Of course, in other embodiments, a plurality of cylindrical mirror supports 20 may be sequentially arranged along the axial direction of the lens barrel assembly 10 , but a nested design is not adopted.

[0069] See also Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 In some embodiments of the present application, the cylindrical mirror angle adjustment mechanism includes a second pressure ring 50, which is fixedly connected to the cylindrical mirror bracket 20 farthest from the first pressure ring 12, and presses against the end side of the cylindrical mirror bracket 20 closest to the first pressure ring 12, so that each cylindrical mirror bracket 20 is axially limited in sequence.

[0070] It should be noted that the second pressure ring 50 is connected and fixed to the cylindrical mirror bracket 20 farthest from the first pressure ring 12 and keeps rotating synchronously. The connection and fixing method therebetween can adopt a detachable connection method (such as screw connection, snap connection, etc.) or a fixed connection method (such as welding, bonding, etc.). The second pressure ring 50 presses against the end side of the "cylindrical mirror bracket 20 closest to the first pressure ring 12" close to the first pressure ring 12. Based on this, the second pressure ring 50 and the cylindrical mirror bracket 20 farthest from the first pressure ring 12 can axially limit the other cylindrical mirror brackets 20 therebetween, so that each cylindrical mirror bracket 20 is axially limited in sequence.

[0071] For example, Figure 4 、 Figure 5 、 Figure 6 As shown, in a specific example of the cylindrical mirror angle adjustment mechanism, the first cylindrical mirror bracket 20a is partially embedded in the second cylindrical mirror bracket 20b, and is axially limited and supported by the second cylindrical mirror bracket 20b. The second cylindrical mirror bracket 20b is partially embedded in the third cylindrical mirror bracket 20c, and is axially limited and supported by the third cylindrical mirror bracket 20c. The second pressure ring 50 is connected and fixed to the third cylindrical mirror bracket 20c, and presses against the end side of the first cylindrical mirror bracket 20a close to the first pressure ring 12. The second pressure ring 50 can limit the first cylindrical mirror bracket 20a and the second cylindrical mirror bracket 20b away from the third cylindrical mirror bracket 20c, so that the first cylindrical mirror bracket 20a, the second cylindrical mirror bracket 20b and the third cylindrical mirror bracket 20c can be axially limited in sequence.

[0072] By adopting the above scheme, the second pressure ring 50 can be connected and fixed to the cylindrical mirror holder 20 farthest from the first pressure ring 12 and keep rotating synchronously, and the second pressure ring 50 can press the end side of the "cylindrical mirror holder 20 closest to the first pressure ring 12" close to the first pressure ring 12 to limit the other cylindrical mirror holders 20 from being away from the "cylindrical mirror holder 20 farthest from the first pressure ring 12", thereby prompting each cylindrical mirror holder 20 to be axially limited in sequence. Based on this, the axial position of each cylindrical mirror holder 20 in the lens barrel assembly 10 can be stabilized, the axial movement of each cylindrical mirror holder 20 can be limited, the accurate positioning and stable installation of the cylindrical mirror holder 20 and its cylindrical mirror 40 can be facilitated, and the structural compactness, structural stability and assembly convenience of the entire cylindrical mirror angle adjustment mechanism can be improved. Moreover, in the process of adjusting the deflection angle of each cylindrical mirror bracket 20 and its cylindrical mirror 40 respectively, the interference caused by the relative axial movement of each cylindrical mirror bracket 20 can be basically eliminated, the adjustment accuracy of the deflection angle of the cylindrical mirror 40 can be improved, and it can be suitable for high-precision optical applications.

[0073] Of course, in other embodiments, other methods can be used to axially limit each cylindrical mirror bracket 20 in sequence. For example, it can be achieved based on the constraints of the lens barrel body 11's own structure (such as a stepped structure, a slot, etc.), it can be achieved based on the matching constraints between the adjustment structure 30 and the adjustment slot 13, it can be achieved based on other structures (such as a pressure ring, etc.), and so on.

[0074] See also Figure 2 、 Figure 3 、 Figure 4 In some embodiments of the present application, the adjustment structure 30 corresponding to the cylindrical mirror holder 20 farthest from the first pressure ring 12 is connected to the circumferential side of the second pressure ring 50. The connection method can be a detachable connection method (such as screw connection, snap connection, etc.) or a fixed connection method (such as welding, bonding, etc.).

[0075] For example, Figure 4 As shown, in a specific example of the cylindrical mirror angle adjustment mechanism, the third adjustment structure 30c corresponding to the third cylindrical mirror bracket 20c farthest from the first pressure ring 12 can be directly connected to the peripheral side of the second pressure ring 50 to be indirectly connected to the third cylindrical mirror bracket 20c.

[0076] By adopting the above solution, since the second pressure ring 50 is fixedly connected to the cylindrical mirror bracket 20 farthest from the first pressure ring 12 and maintains synchronous rotation, the adjustment structure 30 corresponding to the cylindrical mirror bracket 20 farthest from the first pressure ring 12 can be indirectly connected to the cylindrical mirror bracket 20 farthest from the first pressure ring 12 by being directly connected to the circumferential side of the second pressure ring 50, thereby facilitating the circumferential rotation of the cylindrical mirror bracket 20 farthest from the first pressure ring 12. Based on this, the connection method and transmission path between the cylindrical mirror bracket 20 farthest from the first pressure ring 12 and its corresponding adjustment structure 30 can be optimized, and the angular adjustment flexibility of the cylindrical mirror bracket 20 farthest from the first pressure ring 12 can be improved.

[0077] Of course, in other embodiments, the adjustment structure 30 corresponding to the cylindrical mirror holder 20 farthest from the first pressure ring 12 may be directly connected to the circumferential side of the cylindrical mirror holder 20 farthest from the first pressure ring 12 .

[0078] See also Figure 1 、 Figure 2 、 Figure 6 In some embodiments of the present application, the cylindrical mirror angle adjustment mechanism includes a third pressure ring 60, which is connected to the end side of the cylindrical mirror bracket 20 closest to the first pressure ring 12, and is used to cooperate with the cylindrical mirror bracket 20 closest to the first pressure ring 12 to stably install the cylindrical mirror 40.

[0079] It should be noted that the third pressure ring 60 is connected to the end side of the "cylindrical mirror bracket 20 closest to the first pressure ring 12" close to the first pressure ring 12, and the connection method can be a detachable connection method (such as screw connection, snap connection, etc.), or a fixed connection method (such as welding, bonding, etc.). The third pressure ring 60 can limit the cylindrical mirror 40 from escaping from the cylindrical mirror bracket 20 closest to the first pressure ring 12, and even the third pressure ring 60 can press the cylindrical mirror 40 to stabilize the axial installation position of the cylindrical mirror 40. Based on this, the third pressure ring 60 can cooperate with the cylindrical mirror bracket 20 closest to the first pressure ring 12 to achieve stable installation of the cylindrical mirror 40 in the cylindrical mirror bracket 20 closest to the first pressure ring 12. Among them, the cylindrical mirror bracket 20 closest to the first pressure ring 12 can cooperate with the third pressure ring 60 to limit the installation of the cylindrical mirror 40 based on its own slot design.

[0080] For example, Figure 6 As shown, in a specific example of the cylindrical mirror angle adjustment mechanism, the third pressure ring 60 is connected to the end side of the first cylindrical mirror bracket 20a close to the first pressure ring 12, and the third pressure ring 60 presses the first cylindrical mirror 40a. The third pressure ring 60 can cooperate with the first cylindrical mirror bracket 20a to achieve the first cylindrical mirror 40a being stably installed in the first cylindrical mirror bracket 20a, so that the axial installation position of the first cylindrical mirror 40a is stable and will not fall off the first cylindrical mirror bracket 20a.

[0081] By adopting the above solution, the third pressure ring 60 can be connected to the end side of the cylindrical mirror holder 20 closest to the first pressure ring 12, so that the third pressure ring 60 can restrict the cylindrical mirror 40 from escaping from the cylindrical mirror holder 20 closest to the first pressure ring 12, thereby enabling the third pressure ring 60 to cooperate with the cylindrical mirror holder 20 closest to the first pressure ring 12, thereby achieving stable installation of the cylindrical mirror 40 in the cylindrical mirror holder 20 closest to the first pressure ring 12. Based on this, the installation position and installation state of the cylindrical mirror 40 installed in the cylindrical mirror holder 20 closest to the first pressure ring 12 can be stabilized, and the assembly convenience, structural compactness, structural stability, and optical effect of the entire cylindrical mirror angle adjustment mechanism can be improved.

[0082] Of course, in other embodiments, the cylindrical mirror bracket 20 closest to the first pressure ring 12 can achieve stable installation of the cylindrical mirror 40 based on its own slot design, etc., or the first pressure ring 12 or the second pressure ring 50 can cooperate to stably install the cylindrical mirror 40.

[0083] See also Figure 2 In some embodiments of the present application, each adjustment groove 13 is provided on the first pressing ring 12 and is arranged at intervals along the circumference of the first pressing ring 12.

[0084] By adopting the above solution, the layout of each adjustment slot 13 can be optimized, and the layout of each adjustment structure 30 can be correspondingly optimized. Based on this, it is convenient for the operator to access each adjustment slot 13 and adjust each adjustment structure 30 along the circumference of the first pressure ring 12, thereby facilitating the deflection angle adjustment of each cylindrical lens holder 20 and its cylindrical lens 40, thereby improving the convenience of adjustment operation. In addition, since each adjustment slot 13 is integrated into the first pressure ring 12, the processing and forming of the first pressure ring 12 and each adjustment slot 13 can be facilitated, thereby improving the processing convenience, processing efficiency and processing accuracy of the lens barrel assembly 10.

[0085] Of course, in other embodiments, according to the layout requirements of the adjustment grooves 13, each adjustment groove 13 can be set on the barrel wall of the lens barrel body 11; or, each adjustment groove 13 can be partially set on the barrel wall of the lens barrel body 11 and the other part is set on the barrel wall of the first pressure ring 12 (that is, the first pressure ring 12 corresponds to the circumferential part of the lens barrel assembly 10).

[0087] By adopting the above solution, the optical device can improve the overall optical effect and optical accuracy by using the cylindrical mirror angle adjustment mechanism provided in the embodiment of the present application to quickly and effectively adjust the deflection angle of the cylindrical mirror 40 as needed.

[0088] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
