[0034] As described in the background section, an optical tube is a common optical device. Existing optical tubes generally consist of an inner tube and an outer tube, with the outer tube connected to the camera via a bayonet. After the optical tube is assembled with the camera, if there is an angular misalignment between the inner and outer tubes, it will cause the camera to tilt. In this case, the optical tube needs to be disassembled and the relative angle between the inner and outer tubes adjusted. However, currently, the adjustment of the relative angle between the inner and outer tubes is mostly done manually, and the accuracy is affected by the operator's experience, resulting in low efficiency.
[0035] See Figures 1 to 4 As shown, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides a lens barrel angle adjustment device. The lens barrel angle adjustment device is used to adjust the relative angle between the inner lens barrel assembly 81 and the outer lens barrel assembly 82 of the lens barrel 80 to be adjusted. The lens barrel angle adjustment device includes: a device body 10, an angle adjustment module 20, and a positioning module. The angle adjustment module 20 is installed on the device body 10. The positioning module includes a first positioning component 31 and a second positioning component 32. The first positioning component 31 is installed on the device body 10 and is used for positioning and cooperating with the outer lens barrel assembly 82. The second positioning component 32 is installed at the output end of the angle adjustment module 20 and is used for positioning and cooperating with the inner lens barrel assembly 81. When the first positioning component 31 is positioned and cooperating with the outer lens barrel assembly 82, and the second positioning component 32 is positioned and cooperating with the inner lens barrel assembly 81, the angle adjustment module 20 can drive the second positioning component 32 to rotate or swing around the axis of the lens barrel 80 to be adjusted, so as to drive the inner lens barrel assembly 81 to adjust the angle relative to the outer lens barrel assembly 82. The lens barrel angle adjustment device provided in this embodiment uses the positioning cooperation between the first positioning component 31 and the outer lens barrel component 82 to position and fix the outer lens barrel component 82. The positioning cooperation between the second positioning component 32 and the inner lens barrel component 81, and the driving of the angle adjustment module 20 on the second positioning component 32, enable the inner lens barrel component 81 to rotate or swing around the axis of the lens barrel 80 to be adjusted under the drive of the second positioning component 32, thereby realizing the adjustment of the relative angle between the inner lens barrel component 81 and the outer lens barrel component 82. Compared with the traditional manual adjustment method, the lens barrel angle adjustment device provided in this embodiment can not only improve the adjustment efficiency and shorten the adjustment time, but also ensure the accuracy and consistency of the angle adjustment.
[0036] See Figure 3 and Figure 4As shown, it should be noted that the outer lens barrel assembly 82 in this embodiment includes an outer lens barrel body and a connecting bayonet. The connecting bayonet is installed at the first end of the outer lens barrel body, and the outer lens barrel assembly 82 is connected to the camera through the connecting bayonet. The inner lens barrel assembly 81 includes an inner lens barrel body. The lens barrel to be adjusted 80 in this embodiment also includes a lens barrel retaining ring 83. The first end of the inner lens barrel body passes through the second end of the outer lens barrel body into the outer lens barrel body. The lens barrel retaining ring 83 is movably installed in the outer lens barrel body and has a pressed state that is pressed against the first end of the inner lens barrel body and locks the inner lens barrel body and the outer lens barrel body, and a separated state that is separated from the first end of the inner lens body and allows the inner lens barrel body to rotate relative to the outer lens barrel body.
[0037] In some embodiments, the lens barrel angle adjustment device further includes a retaining ring locking module 70. This retaining ring locking module 70 can drive and cooperate with the lens barrel retaining ring 83. After the relative angle between the inner lens barrel assembly 81 and the outer lens barrel assembly 82 is adjusted, the lens barrel angle adjustment device can drive the retaining ring 83 through the retaining ring locking module 70, switching the retaining ring 83 from a separated state to a pressed state. By providing the retaining ring locking module 70, the lens barrel angle adjustment device can quickly switch the retaining ring 83 from a separated state to a pressed state after the relative angle between the inner lens barrel assembly 81 and the outer lens barrel assembly 82 is adjusted, thereby achieving a fixed connection between the inner lens barrel assembly 81 and the outer lens barrel assembly 82.
[0038] In some embodiments, the pressure ring locking and fixing module 70 in this embodiment includes a pressure ring locking and fixing fixture. The pressure ring locking and fixing fixture is provided with a mating protrusion, and the lens barrel pressure ring 83 is provided with a mating recess adapted to the mating protrusion. The pressure ring locking and fixing fixture is driven to connect with the lens barrel pressure ring 83 through the mating of the mating protrusion and the mating recess.
[0039] In some embodiments, the first positioning component 31 in this embodiment includes a first fixing seat 311. The first fixing seat 311 in this embodiment is provided with a first positioning groove 3111. The structure of the first positioning groove 3111 is adapted to the structure of the outer lens barrel assembly 82. The radial sliding of the outer lens barrel assembly 82 can be restricted by the cooperation between the first positioning groove 3111 and the outer lens barrel assembly 82.
[0040] In some embodiments, the first positioning component 31 in this embodiment further includes a positioning pin 312. The first end of the outer lens barrel component 82 in this embodiment is provided with a camera positioning hole 821. The positioning pin 312 in this embodiment is installed on the first fixed base 311 and is adapted to the camera positioning hole 821. The cooperation between the positioning pin 312 and the camera positioning hole 821 can restrict the circumferential rotation of the outer lens barrel component 82.
[0041] In some embodiments, the camera positioning hole 821 in this embodiment is disposed at the connection bayonet, and the camera can be positioned at the connection bayonet by cooperating with the camera positioning hole 821. By reusing the structure of the camera positioning hole 821, the camera, the outer lens barrel assembly 82 and the angle adjustment device can have a unified positioning reference, ensuring that the angle adjustment amount of the lens barrel 80 to be adjusted directly corresponds to the deflection of the camera's imaging optical axis, and realizing the visual verification and precise correction of the adjustment effect.
[0042] In some embodiments, the second positioning component 32 in this embodiment includes a second fixing seat 321. The second fixing seat 321 in this embodiment is provided with a second positioning groove 3211. The structure of the second positioning groove 3211 is adapted to the structure of the endoscope tube assembly 81. The cooperation between the second positioning groove 3211 and the outer endoscope tube assembly 82 can restrict the radial sliding and circumferential rotation of the outer endoscope tube assembly 82.
[0043] See Figure 1 and Figure 2 As shown, in a specific embodiment, the lens barrel angle adjustment device further includes a distance adjustment module 40. The distance adjustment module 40 is installed on the main body 10 of the device, and the angle adjustment module 20 is installed at the output end of the distance adjustment module 40. When the first positioning component 31 is positioned and engaged with the outer lens barrel component 82, and the second positioning component 32 is positioned and engaged with the inner lens barrel component 81, the first positioning component 31 and the second positioning component 32 are arranged at intervals along the axial direction of the lens barrel 80 to be adjusted. The distance adjustment module 40 can drive the angle adjustment module 20 to move along the axial direction of the lens barrel 80 to be adjusted, and drive the second positioning component 32 to cooperate with the first positioning component 31 to clamp or release the lens barrel 80 to be adjusted. By setting a distance adjustment module 40 on the main body 10 of the device and installing an angle module at the output end of the distance adjustment module 40, the lens barrel angle adjustment device can adjust the relative distance between the first positioning component 31 and the second positioning component 32 by axially driving the angle adjustment module 20 through the distance adjustment module 40. This enables the rapid clamping and positioning of the lens barrel 80 to be adjusted, ensuring that the lens barrel 80 to be adjusted does not undergo axial displacement during relative angle adjustment, thereby effectively improving the adjustment accuracy and operating efficiency of the lens barrel angle adjustment device for the lens barrel 80 to be adjusted.
[0044] See Figure 1 and Figure 2As shown, in a specific embodiment, the angle adjustment module 20 includes a first base assembly 21 and a first slide assembly 22. The first base assembly 21 is installed on the main body 10 of the device and forms a virtual swing axis. The first slide assembly 22 slides in cooperation with the first base assembly 21 along the circumference of the virtual swing axis and can swing around the virtual swing axis. The first slide assembly 22 forms the output end of the angle adjustment module 20. When the first positioning assembly 31 is positioned in cooperation with the outer lens tube assembly 82 and the second positioning assembly 32 is positioned in cooperation with the inner lens tube assembly 81, the virtual swing axis is collinear with the axis of the lens tube 80 to be adjusted. By setting the virtual swing axis of the first base assembly 21 to be collinear with the axis of the lens barrel 80 to be adjusted when the first positioning assembly 31 is positioned and engaged with the outer lens barrel assembly 82 and the second positioning assembly 32 is positioned and engaged with the inner lens barrel assembly 81, and simultaneously setting the first slider assembly to be slidably engaged with the first base assembly 21 along the circumference of the virtual swing axis, the second positioning assembly 32 installed on the first slider assembly can drive the inner lens barrel assembly 81 positioned and engaged with it to swing precisely around the axis of the lens barrel 80 to be adjusted as the first slider assembly slides, so that the lens barrel angle adjustment device in this embodiment can perform high-precision angle adjustment of the lens barrel 80 to be adjusted.
[0045] In some embodiments, a vertical plane passing through the virtual swing axis is used as the reference plane, and the virtual swing axis is used as the reference axis. The swing angle range of the first slide assembly 22 is +25° to -25°. By setting the swing angle range of the first slide assembly 22 to +25° to -25°, a sufficient angle adjustment range can be ensured for the lens barrel angle adjustment device, improving the versatility of the lens barrel angle adjustment device. Of course, in other embodiments, the swing angle of the first slide assembly 22 in this embodiment can also be other ranges, such as +10° to -10°, +15° to -15°, etc.
[0046] In some embodiments, the first base assembly 21 in this embodiment is provided with an arc-shaped guide rail, and the axis of the center of the arc-shaped guide rail forms a virtual swing axis of the first base assembly 21. In this embodiment, the first slide assembly 22 is provided with an arc-shaped slider adapted to the arc-shaped guide rail. The first slide assembly 22 swings around the virtual swing axis through the sliding engagement of the arc-shaped slider and the arc-shaped guide rail. By setting the sliding engagement between the arc-shaped guide rail and the arc-shaped slider, the first slide assembly 22 can swing smoothly along a precise arc trajectory, enabling the endoscope barrel angle adjustment device in this embodiment to perform high-precision angle adjustment of the endoscope barrel assembly 81.
[0047] In one specific embodiment, the angle adjustment module 20 includes a first adjustment component, which is mounted on the first base assembly 21 and drivesly engages with the first slide assembly 22. This first adjustment component is used to adjust the relative positions of the first slide assembly 22 and the first base assembly 21 in the circumferential direction along the virtual swing axis. By providing the first adjustment component on the first base assembly 21 and drivingly engaging with the first slide assembly 22, the angle adjustment module 20 in this embodiment can precisely adjust the relative positions of the first slide assembly 22 and the first base assembly 21 in the circumferential direction along the virtual swing axis, thereby achieving high-precision fine-tuning of the angle of the endoscope tube assembly 81.
[0048] In some embodiments, the first adjusting component in this embodiment includes an adjusting worm gear. The first slide assembly 22 in this embodiment is provided with a worm wheel structure adapted to the adjusting worm gear. The adjusting worm gear is rotatably mounted on the first base assembly 21, and the worm wheel structure cooperates with it. Rotating the adjusting worm gear can drive the first slide assembly 22 to slide, thereby adjusting the relative position of the first slide assembly 22. Of course, in other embodiments, the first adjusting component in this embodiment can also be any other device or component capable of adjusting the relative position of the first slide assembly 22.
[0049] In one specific embodiment, the angle adjustment module 20 includes a first locking component, which is installed on one of the first base component 21 and the first slide component 22. The first locking component has a first locking state that abuts against the other of the first base component 21 and the first slide component 22 to lock the relative positions of the first slide component 22 and the first base component 21 in the circumferential direction of the virtual swing axis, and a first unlocking state that is separated from the other of the first base component 21 and the first slide component 22. By providing a first locking component on one of the first base assembly 21 and the first slide assembly 22, the angle adjustment module 20 in this embodiment can lock the relative position of the first slide assembly 22 and the first base assembly 21 in the circumferential direction of the virtual swing axis through the abutting cooperation between the first locking component and the other of the first base assembly 21 and the first slide assembly 22. This allows the lens barrel angle adjustment device in this embodiment to maintain the relative position of the outer lens barrel assembly 82 and the inner lens barrel assembly 81 unchanged after the angle of the lens barrel 80 to be adjusted is adjusted, which facilitates the subsequent fixed assembly operation of the outer lens barrel assembly 82 and the inner lens barrel assembly 81.
[0050] In some embodiments, the first locking component in this embodiment includes a first locking bolt. The first slide assembly 22 in this embodiment has a first threaded mounting hole that is adapted to the first locking bolt. The first locking bolt engages with the first threaded mounting hole. Tightening the first locking bolt allows it to pass through the first threaded mounting hole and abut against the first base assembly 21, thereby locking and fixing the first base assembly 21 and the first slide assembly 22. The extension direction of the first threaded mounting hole is perpendicular to the sliding direction of the first slide assembly 22. Of course, in other embodiments, the first locking component in this embodiment can also be any other device or component capable of locking the first base assembly 21 and the first slide assembly 22.
[0051] See Figure 1 and Figure 2 As shown, in a specific embodiment, the distance adjustment module 40 includes a second base assembly 41 and a second slide assembly 42. The second base assembly 41 is mounted on the main body 10 of the device, and the second slide assembly 42 is slidably engaged with the second base assembly 41. The second slide assembly 42 forms the output end of the distance adjustment module 40, and when the first positioning assembly 31 is engaged with the outer endoscope assembly 82 and the second positioning assembly 32 is engaged with the inner endoscope assembly 81, the sliding direction of the second slide assembly 42 is parallel to the axis of the endoscope 80 to be adjusted. By setting the sliding direction of the second slide assembly 42 to be parallel to the axis of the endoscope 80 to be adjusted when the first positioning assembly 31 is engaged with the outer endoscope assembly 82 and the second positioning assembly 32 is engaged with the inner endoscope assembly 81, the angle adjustment module 20 mounted on the second slider assembly can move the second positioning assembly 32 mounted thereon as the second slider assembly slides, cooperating with the first positioning assembly 31 to clamp or release the endoscope 80 to be adjusted.
[0052] In some embodiments, the second base assembly 41 in this embodiment is provided with a linear guide rail, and the second slide assembly 42 in this embodiment is provided with a linear slider adapted to the linear guide rail. The second slide assembly 42 slides on the second base assembly 41 through the sliding cooperation between the linear slider and the linear guide rail.
[0053] In one specific embodiment, the distance adjustment module 40 includes a second adjustment component. The second adjustment component is mounted on the second base assembly 41 and is in kinetic engagement with the second slide assembly 42, used to adjust the relative position of the second slide assembly 42 and the second base assembly 41. By providing the second adjustment component on the second base assembly 41 in kinetic engagement with the second slide assembly 42, the distance adjustment module 40 in this embodiment can adjust the relative position of the second slide assembly 42 and the second base assembly 41 via the second adjustment component, thereby achieving precise clamping or release of the lens barrel 80 to be adjusted.
[0054] In some embodiments, the first adjusting component in this embodiment includes an adjusting bolt. A second threaded mounting hole is provided on the second base assembly 41, which is adapted to the adjusting bolt. The adjusting bolt passes through the second threaded mounting hole and abuts against the second slide assembly 42. Tightening the adjusting bolt can adjust the relative position of the second slide assembly 42 and the second base assembly 41, wherein the extending direction of the second threaded mounting hole is parallel to the sliding direction of the second slide assembly 42. Of course, in other embodiments, the second adjusting component in this embodiment can also be any other device or component capable of adjusting the relative position of the second slide assembly 42.
[0055] In some embodiments, the distance adjustment module 40 in this embodiment further includes an elastic reset component. The elastic reset component in this embodiment is installed between the second base assembly 41 and the second slide assembly 42 and is used to apply elastic force to the second slide assembly 42 so that the second slide assembly 42 maintains contact with the adjusting bolt when no external force is applied.
[0056] In one specific embodiment, the distance adjustment module 40 includes a second locking component. The second locking component is mounted on one of the second base assembly 41 and the second slide assembly 42. The second locking component has a second locking state, which abuts against the other of the second base assembly 41 and the second slide assembly 42 to lock the relative position of the second slide assembly 42 and the second base assembly 41, and a second unlocking state, which is separated from the other of the second base assembly 41 and the second slide assembly 42. By providing the second locking component on one of the second base assembly 41 and the second slide assembly 42, the distance adjustment module 40 in this embodiment can lock the relative position of the second slide assembly 42 and the second base assembly 41 through the abutment of the second locking component with the other of the second base assembly 41 and the second slide assembly 42. This allows the lens barrel angle adjustment device in this embodiment to maintain a stable clamping of the lens barrel 80 to be adjusted, ensuring that the relative axial position of the outer lens barrel assembly 82 and the inner lens barrel assembly 81 remains unchanged during the angle adjustment process.
[0057] In some embodiments, the second locking assembly in this embodiment includes a second locking bolt. The second slide assembly 42 in this embodiment is provided with a third threaded mounting hole, which is adapted to the second locking bolt. The second locking bolt engages with the third threaded mounting hole. Tightening the second locking bolt allows it to pass through the third threaded mounting hole and abut against the second base assembly 41, thereby locking and fixing the second base assembly 41 and the second slide assembly 42. The extension direction of the third threaded mounting hole is perpendicular to the sliding direction of the second slide assembly 42. Of course, in other embodiments, the second locking assembly in this embodiment can also be any other device or component capable of locking the second base assembly 41 and the second slide assembly 42.

By setting the first adapter module 50 to connect the device body 10 and the first positioning component 31, first positioning components 31 of different specifications can be installed on the same device body 10 through the corresponding first adapter module 50, eliminating the need to manufacture device bodies 10 of different specifications, thus reducing the production cost and debugging time of the lens barrel angle adjustment device.
[0059] See Figure 1 and Figure 2 As shown, in one specific embodiment, the lens barrel angle adjustment device further includes a second adapter module 60. The second adapter module 60 is installed on the device body 10, and the distance adjustment module 40 is installed on the second adapter module 60. By setting the second adapter module 60 to connect the device body 10 and the distance adjustment module 40, distance adjustment modules 40 of different specifications can be installed on the same device body 10 through the corresponding second adapter module 60, eliminating the need to manufacture device bodies 10 of different specifications, thus reducing the production cost and debugging time of the lens barrel angle adjustment device.
[0060] In some embodiments, the device body 10 in this embodiment is an optical platform with array mounting holes. Setting the device body 10 as an optical platform with array mounting holes allows the first adapter module 50 and the second adapter module 60 to be flexibly positioned via the array mounting holes on the optical platform, which improves the versatility of the lens barrel angle adjustment device.
[0061] In some embodiments, before adjusting the angle of the lens barrel 80 to be adjusted using the lens barrel angle adjustment device of this embodiment, the lens barrel 80 to be adjusted is first mounted on a camera, and a real-world image is captured using the camera. By comparing the tilt of the captured image with the actual image, the required angle adjustment of the lens barrel 80 is determined. Then, the angle of the lens barrel 80 to be adjusted can be adjusted using the lens barrel angle adjustment device of this embodiment. When adjusting the angle of the lens barrel 80 to be adjusted using the lens barrel angle adjustment device of this embodiment, the inner and outer lens barrel assemblies 82 of the lens barrel 80 to be adjusted are first positioned by the positioning module. Positioned on the second positioning component 32 and the first positioning component 31, the lens barrel 80 to be adjusted is then axially clamped between the first positioning component 31 and the second positioning component 32 by the distance adjustment module 40. Then, the relative angle of the inner and outer lens barrel components 82 is adjusted by the angle adjustment module 20. After the relative angle of the inner and outer lens barrel components 82 is adjusted, the inner and outer lens barrel components 82 are locked by the pressure ring locking and fixing module 70. Finally, the lens barrel 80 to be adjusted is released from between the first positioning component 31 and the second positioning component 32 by the distance adjustment module 40. At this time, the angle adjustment of the lens barrel 80 to be adjusted is completed.
[0062] In summary, the lens barrel angle adjustment device provided in this embodiment has at least the following beneficial technical effects: The lens barrel angle adjustment device provided in this embodiment fixes the outer lens barrel assembly 82 by positioning the first positioning component 31 with the outer lens barrel assembly 82, and by positioning the second positioning component 32 with the inner lens barrel assembly 81, and by driving the second positioning component 32 by the angle adjustment module 20, the inner lens barrel assembly 81 can rotate or swing around the axis of the lens barrel 80 to be adjusted under the drive of the second positioning component 32, thereby realizing the adjustment of the relative angle between the inner lens barrel assembly 81 and the outer lens barrel assembly 82. Compared with the traditional manual adjustment method, the lens barrel angle adjustment device provided in this embodiment can not only improve the adjustment efficiency and shorten the adjustment time, but also ensure the accuracy and consistency of the angle adjustment.
[0063] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
