Description

Technical Field

[0001] This invention belongs to the field of plane mirror support technology, and specifically relates to a plane mirror support device with adjustable support angle. Background Technology

[0002] As a fundamental optical element, plane mirrors play an irreplaceable role in scientific research, industrial production, medical aesthetics, daily life, and artistic creation. From constructing optical paths in laboratory experiments to daily grooming in dressing rooms; from reflecting stage lights to assisting with lighting in photography studios, the applications of plane mirrors are extremely wide-ranging. However, different scenarios place varying demands on the support methods and angle adjustment capabilities of plane mirrors, and existing support devices still have some shortcomings in meeting these needs.

[0003] In setting up precision optical experiments, plane mirrors need to reflect light beams to a target location at a specific angle. These applications have extremely stringent requirements for angle adjustment, demanding not only a wide range of coarse adjustment capabilities to establish the basic optical path, but also micrometer-level fine-tuning capabilities to achieve precise alignment and optimization of the optical path. Researchers often need to repeatedly adjust the angle within millimeter-level movements. Traditional support devices struggle to simultaneously meet the dual demands of wide-range adjustment and high-precision positioning. While existing technologies can achieve fine-tuning of the plane mirror support angle, the operation is too cumbersome and lacks the ability to provide rapid and intuitive angle adjustments. Summary of the Invention

[0010] In a preferred embodiment, a placement frame is fixedly installed on the upper rear side of the base.

[0011] In a preferred embodiment, the support frame has cavities inside, the outer ring of the middle section of the support rod is rotatably connected to the cavity inside the support frame, and the outer ring of the support rod located in the cavity of the support frame is movably sleeved with a rotating ring, which is rotatably connected to the inner wall of the support frame.

[0012] In a preferred embodiment, the inner ring of the middle section of the support rod has a guide groove, a connecting block is slidably connected in the guide groove, the outer ring of the connecting block extends out of the guide groove, a pull rod is fixedly connected to the side of the connecting block away from the mirror chamber mechanism, and the pull rod is slidably connected to the inner cavity of the support rod and extends out of the support rod. The inner ring of the swivel ring has a connecting groove, and the entrance of the connecting groove faces the side of the connecting block.

[0013] In a preferred embodiment, the rotating rod is fixedly connected to the lower end of the outer ring of the rotating ring. The lower end of the rotating rod has a cavity, and an extension rod is slidably connected inside the cavity. The lower end of the extension rod is rotatably connected to a slider.

[0015] The technical effects achieved by this invention are as follows: The adjustment and drive units of this invention enable rapid adjustment of the orientation of the plane mirror and quick switching to precise fine-tuning, ensuring the accuracy and efficiency of the adjustment. In use, the lifting platform descends, driving motor A to descend, connecting the drive block with the large gear. Then, motor A drives the drive block and the large gear to rotate, causing the small gear ring to rotate, which in turn drives the mounting column to rotate at high speed. Subsequently, the lifting platform rises, connecting the drive block with the small gear, and then drives the large gear ring to rotate, which in turn drives the mounting column to rotate slowly, thus achieving fine-tuning of the angle. The switching and fine-tuning parts of this invention can achieve rapid adjustment and precise fine-tuning of the elevation angle of the plane mirror, ensuring adjustment efficiency. In use, the support rod rotates around the support frame, driving the mirror chamber mechanism to rotate and adjust the elevation angle. Then, it pushes the connecting block to connect with the rotating ring. The lead screw drives the slider to move, and the slider drives the extension rod and the rotating rod to rotate, driving the rotating ring and the support rod to rotate slowly, thereby realizing the fine-tuning of the elevation angle of the mirror chamber mechanism.

[0022] Please see the appendix Figures 1 to 5 , Figures 7 to 12 As shown, this embodiment provides a plane mirror support device with an adjustable support angle, including: A base 10 is provided, with a mounting column 12 connected to the upper end of the base 10. A support frame 14 is connected to the upper end of the mounting column 12. A support rod 15 is rotatably connected inside the support frame 14. A mirror chamber mechanism 18 is connected to the support rod 15. Adjustment unit 20, the adjustment unit 20 includes a lifting platform 22, a motor A23 connected to the lifting platform 22, and a drive block 25 connected to the output shaft of the motor A23; The drive unit 30 includes a small gear ring 31, which is mounted on the outer ring of the mounting post 12. A large gear ring 32 is connected to the outer ring of the mounting post 12. A large gear 34 and a small gear 35 are provided on the rear side of the base 10. The large gear 34 meshes with the small gear ring 31, and the small gear 35 meshes with the large gear ring 32. The drive block 25 is connected to one of the large gear 34 and the small gear 35. The switching part 40 includes a rotating ring 41, which is disposed on the outer ring of the support rod 15. A connecting block 43 is slidably connected inside the support rod 15, and the connecting block 43 is disposed on the side of the rotating ring 41. The fine-tuning part 50 includes a rotating rod 51 connected below the rotating ring 41. An extension rod 52 is movably sleeved at the lower end of the rotating rod 51. A slider 53 is connected to the lower end of the extension rod 52. A lead screw 54 is connected to the lower end of the support frame 14. The slider 53 is threadedly connected to the lead screw 54. The drive unit 30 is divided into two states. In the first state, the drive block 25 is connected to the large gear 34, which drives the small gear ring 31 to rotate rapidly. In the second state, the lifting platform 22 drives the motor A23 and the drive block 25 to rise and switch to connect with the small gear 35, which drives the large gear ring 32 to rotate slowly. After the mirror chamber mechanism 18 and the support rod 15 rotate along the inner ring of the support frame 14, the connecting block 43 is inserted into the rotating ring 41, and the lead screw 54 drives the slider 53 and the rotating rod 51 to rotate, thereby driving the mirror chamber mechanism 18 to rotate slightly.

[0023] It should be noted that, in order to ensure the stable use of the device, the device should be equipped with electrical control and hydraulic drive components to control the stable operation and use of each component within the device.

[0024] In this embodiment, during use, the lifting platform 22 descends, driving the motor A23 to descend as well, connecting the drive block 25 to the large gear 34. The motor A23 then drives the drive block 25 and the large gear 34 to rotate, causing the small gear ring 31 to rotate and the mounting column 12 to rotate at high speed. Subsequently, the lifting platform 22 rises, connecting the drive block 25 to the small gear 35, and again drives the large gear ring 32 to rotate, causing the mounting column 12 to rotate slowly, thus achieving fine-tuning of the angle. When adjusting the elevation angle, the support rod 15 rotates around the support frame 14, causing the mirror chamber mechanism 18 to rotate and adjust the elevation angle. Then, it pushes the connecting block 43 to connect with the rotating ring 41. The lead screw 54 moves, driving the slider 53 to move. The slider 53 then drives the extension rod 52 and the rotating rod 51 to rotate, causing the rotating ring 41 and the support rod 15 to rotate slowly, thus achieving fine-tuning of the elevation angle of the mirror chamber mechanism 18.

[0025] Secondly, please refer to it again. Figures 1 to 3 The lower end of the base 10 is fixedly connected to the support 11. The inner ring of the base 10 is provided with an annular through groove, and the through groove is rotatably connected to the mounting column 12 by ball bearing. The upper end of the mounting column 12 is fixedly connected to the base plate 13, and the left and right sides of the upper end of the base plate 13 are fixedly connected to the support frame 14. The upper middle part of each of the two sets of support frames 14 is rotatably connected to a support rod 15 via a ball bearing, and the ends of the two sets of support rods 15 that are far apart from each other extend out of the support frame 14 and are fixedly connected to a push frame 16. The lower ends of the two sets of support frames 14 that are far apart from each other are rotatably connected to a hydraulic rod 17 via a rotating shaft. The upper ends of the hydraulic rods 17 are rotatably connected to the inner cavity of the push frame 16 via a rotating shaft. The ends of the two sets of support rods 15 that are close to each other are fixedly connected to a mirror chamber mechanism 18.

[0026] It should be noted that the upper and lower sides of the contact part between the mounting post 12 and the base 10 are provided with limiting rings with a diameter larger than that of the mounting post 12, thereby ensuring the stability of the mounting post 12. The part connecting the push frame 16 and the hydraulic rod 17 is provided with an arc-shaped through groove (such as...). Figure 1 and Figure 2 As shown), the arc-shaped block connected to the output end of the hydraulic rod 17 is movably sleeved in the through groove, and the center of the arc-shaped through groove is the same as the center of the support rod 15. Here, when the hydraulic rod 17 drives the push frame 16 and the support rod 15 to rotate, the upper end of the hydraulic rod 17 will first be moved to the upper end of the arc through groove, and then the push frame 16 will be driven to rotate. This avoids the rigidly fixed hydraulic rod 17 from affecting the fine-tuning rotation of the support rod 15 during subsequent fine-tuning operations. Support 11 should have a height adjustment function (this is a common technical structure required in the prior art for adjusting the height of a plane mirror, which will not be described in detail here), so as to realize the height adjustment of the plane mirror support.

[0027] In this embodiment, during use, the output end of the hydraulic rod 17 extends and retracts, driving the push frame 16 and the support rod 15 to rotate, thereby driving the mirror chamber mechanism 18 to rotate synchronously, thus achieving preliminary adjustment of the elevation angle of the mirror chamber mechanism 18.

[0028] Secondly, please refer to it again. Figure 2 , Figures 4 to 6 The adjustment unit 20 also includes two sets of electric actuators 21. Two sets of protective shells are provided on the upper rear side of the base 10. The two sets of electric actuators 21 are respectively installed in the inner cavity of the two sets of protective shells. The output ends of the two sets of electric actuators 21 extend out of the protective shells and are fixedly connected to the lifting platform 22. The upper end of the lifting platform 22 is fixedly installed with a motor A23. The output shaft of the motor A23 is fixedly connected with a rotating shaft 24. The upper end of the rotating shaft 24 is fixedly connected with a drive block 25.

[0029] It should be noted that the two sets of electric actuators 21 should be connected in series to control the simultaneous extension and retraction of the two sets of electric actuators 21, so as to avoid affecting the lifting stability of the lifting platform 22. The drive block 25 has a hexagonal structure, which facilitates the subsequent rotation of the pinion 35 and the gear 34.

[0030] In this embodiment, when in use, the electric actuator 21 drives the lifting platform 22 to move up and down through telescopic movement, thereby driving the motor A23, the rotating shaft 24 and the drive block 25 to move up and down synchronously, providing power support for subsequent fast and slow speed adjustment and switching.

[0031] Secondly, please refer to it again. Figures 3 to 6 A small toothed ring 31 is fixedly connected to the middle of the outer ring of the mounting post 12, and a large toothed ring 32 is fixedly connected to the upper end of the outer ring of the mounting post 12. A placement frame 33 is fixedly installed on the upper rear side of the base 10. A large gear 34 is rotatably connected to the lower middle part of the placement frame 33 via a ball bearing. The outer ring of the large gear 34 meshes with the outer ring of the small gear ring 31. A small gear 35 is rotatably connected to the upper middle part of the placement frame 33 via a ball bearing. The outer ring of the small gear 35 meshes with the outer ring of the large gear ring 32. The small gear 35 and the large gear 34 are located on the same axis. Both the small gear 35 and the large gear 34 have drive grooves 36 in their middle parts. The drive block 25 is slidably connected to one of the two sets of drive grooves 36.

[0032] It should be noted that both sets of drive slots 36 are hexagonal through slots, and their internal width is adapted to the drive block 25, so that the drive block 25 can slide up and down in the drive slot 36 and also drive the drive slot 36 to rotate. Here, the angle adjustment of the mounting column 12 is divided into two states. When a large-range and rapid angle adjustment is required, the drive block 25 is connected to the drive groove 36 in the large gear 34, driving the large gear 34 and the small gear ring 31 to rotate, so that the mounting column 12 can be adjusted quickly to a large angle. When a small-range and precise fine adjustment is required, the drive block 25 is driven to rise and connect with the small gear 35. The small gear 35 drives the large gear ring 32 to rotate, so that the mounting column 12 can be adjusted slowly to find the angle that the device needs to support. A clearance is provided between the large gear 34 and the small gear 35 to prevent the large gear 34 or the small gear 35 from rotating and causing the other structure to rotate as well, thus affecting the stable rotation of the device.

[0033] In this embodiment, when adjusting the orientation of the plane mirror, the lifting platform 22 first drives the motor A23 and the drive block 25 to descend, causing the drive block 25 to insert into the drive groove 36 in the middle of the large gear 34. At this time, the motor A23 starts, driving the drive block 25 to rotate via the rotating shaft 24, and the drive block 25 drives the large gear 34 to rotate synchronously. The rotation of the large gear 34 drives the small gear ring 31 and the mounting column 12 to rotate rapidly, thereby achieving a wide range of rapid adjustments to the orientation of the mirror chamber mechanism 18. When a small-angle precise fine adjustment is required, the electric push rod 21 drives the lifting platform 22 to rise, driving the motor A23 and the drive block 25 to move upward, causing the drive block 25 to disengage from the drive groove 36 of the large gear 34 and insert into the drive groove 36 in the middle of the small gear 35. At this time, motor A23 starts again, and drive block 25 drives pinion 35 to rotate. Pinion 35 meshes with large gear ring 32 on the outer ring of mounting post 12. Since pinion 35 has fewer teeth and large gear ring 32 has more teeth, the rotation of pinion 35 will drive large gear ring 32 and mounting post 12 to rotate at a slower speed and with more precise accuracy, thereby realizing a small range of precise fine adjustment of the orientation of mirror chamber mechanism 18, ensuring that the plane mirror can be aligned with the target direction.

[0034] Please refer to it again. Figures 7 to 12 The support frame 14 has cavities inside. The outer ring of the middle section of the support rod 15 is rotatably connected to the cavity inside the support frame 14. The outer ring of the support rod 15 located in the cavity of the support frame 14 is movably sleeved with a rotating ring 41. The rotating ring 41 is rotatably connected to the inner wall of the support frame 14 through a ball bearing. The middle section of the support rod 15 has a guide groove 42 in the inner ring. A connecting block 43 is slidably connected in the guide groove 42. The outer ring of the connecting block 43 extends out of the guide groove 42. A pull rod 44 is fixedly connected to the side of the connecting block 43 away from the mirror chamber mechanism 18. The pull rod 44 is slidably connected in the inner cavity of the support rod 15 and extends out of the support rod 15. The inner ring of the rotating ring 41 has a connecting groove 45, and the entrance of the connecting groove 45 faces the side of the connecting block 43.

[0035] It should be noted that the inner diameter of the connecting groove 45 is adapted to the connecting block 43, so that the connecting block 43 can be inserted into the connecting groove 45 by pushing the pull rod 44; The end of the pull rod 44 away from the connecting block 43 passes through and extends out of the support rod 15, and the length of the extension of the support rod 15 should be greater than the length of the moving process of the connecting block 43, so as to ensure that the pull rod 44 can stably push the connecting block 43 into the connecting groove 45; A viewing window (such as) is provided on the outer side of the support frame 14 above the support rod 15. Figure 3 As shown), a transparent layer is installed inside to observe whether the connecting block 43 can be inserted into the connecting groove 45. If it cannot be inserted, the rotating ring 41 can be rotated by the fine-tuning part 50 so that the connecting block 43 can be aligned with the connecting groove 45 for easy insertion. In this normal state, the rotating ring 41 does not participate in the rotational movement of the support rod 15. After the connecting block 43 and the connecting groove 45 are connected, the support rod 15 is integrated with the rotating ring 41 through the connecting block 43. At this time, the rotating ring 41 can participate in the rotational movement of the support rod 15, which makes it easier to finely adjust the rotation angle of the support rod 15 through the rotating ring 41 in the future.

[0036] In this embodiment, when adjusting the elevation angle of the plane mirror, the hydraulic rod 17 pushes the push frame 16 and the support rod 15 to rotate, thereby driving the mirror chamber mechanism 18 to rotate synchronously, achieving a preliminary and relatively large adjustment of the elevation angle of the mirror chamber mechanism 18. After the preliminary adjustment is completed, the operator can observe the relative position of the connecting block 43 and the connecting groove 45 on the rotating ring 41 through the viewing window on the outside of the support frame 14. After confirming that the positions are aligned, the pull rod 44 is pushed, causing the connecting block 43 to move along the guide groove 42 towards the rotating ring 41 until the connecting block 43 is fully inserted into the connecting groove 45 of the inner ring of the rotating ring 41. At this time, the support rod 15 and the rotating ring 41 are connected through the cooperation of the connecting block 43 and the connecting groove 45. The rotation of the rotating ring 41 will directly drive the support rod 15 and the mirror chamber mechanism 18 to rotate, preparing for subsequent fine-tuning of the elevation angle.

[0037] Please refer to it again. Figures 11 to 14 The rotating rod 51 is fixedly connected to the lower end of the outer ring of the rotating ring 41. The lower end of the rotating rod 51 has a cavity. An extension rod 52 is slidably connected in the cavity. The lower end of the extension rod 52 is rotatably connected to the slider 53 through a rotating shaft. The slider 53 is slidably connected to the lower end of the inner cavity of the support frame 14 and the base plate 13. The middle part of the inner cavity of the base plate 13 is rotatably connected to the lead screw 54 through a ball bearing. The outer ring of the middle section of the lead screw 54 is threadedly connected to the middle part of the slider 53. A motor B55 is fixedly installed in the middle of the inner cavity of the support frame 14. A sprocket 56 is fixedly connected to the output shaft of the motor B55. A transmission rod 57 is rotatably connected to the middle of the inner cavity of the base plate 13 through a ball bearing. A chain A58 is engaged with the outer ring of the sprocket 56. The lower end of the chain A58 is engaged with the outer ring of the rear end of the transmission rod 57. A chain B59 is engaged with the outer ring of the front end of the transmission rod 57. The other end of the chain B59 is engaged with the outer ring of the front end of the lead screw 54.

[0038] It should be noted that a track (such as a rail) is fixedly connected to the lower end of the inner cavity of the base plate 13. Figure 14 As shown in the figure, this limits the range of motion of slider 53 and ensures the stability of slider 53; Both ends of the transmission rod 57 are equipped with sprockets 56, and the front end of the lead screw 54 is also equipped with a sprocket 56, thereby ensuring a stable connection between chain A58 and chain B59. Here, when motor B55 drives lead screw 54 to rotate via transmission rod 57, it will cause slider 53 to move, thereby causing extension rod 52 and rotating rod 51 to rotate around the upper inner cavity of support frame 14, and causing connecting block 43 and support rod 15 to rotate, driving push frame 16 and mirror chamber mechanism 18 to rotate for fine adjustment of elevation angle. During this period, the arc groove in the middle of push frame 16 will slide on the outer ring of hydraulic rod 17. When hydraulic rod 17 needs to be connected to drive, hydraulic rod 17 needs to be extended and moved back to the upper end of arc groove first, and then connecting block 43 can be pulled out.

[0039] In this embodiment, after the rotating ring 41 is connected to the support rod 15, the motor B55 drives the sprocket 56 to rotate, and the sprocket 56 drives the transmission rod 57 to rotate via the chain A58. The transmission rod 57 drives the lead screw 54 to rotate synchronously via the chain B59. The lead screw 54 then drives the slider 53 to slide, driving the extension rod 52 and the rotating rod 51 to rotate. The rotating rod 51 then drives the rotating ring 41 to rotate, and the rotating ring 41 drives the support rod 15 to rotate via the connecting block 43, thus making a small angle adjustment to the elevation of the mirror chamber mechanism 18. During this fine-tuning process, the arc-shaped through groove in the middle of the push frame 16 will slide along the arc-shaped block connected to the output end of the hydraulic rod 17. Since the upper end of the hydraulic rod 17 has been moved to the upper position of the arc-shaped through groove, it will not rigidly hinder the fine-tuning rotation of the support rod 15. By controlling the forward and reverse rotation of the motor B55, the reciprocating movement of the slider 53 can be realized, thereby driving the mirror chamber mechanism 18 to make precise adjustments to the elevation until the desired angle position is reached. When a larger elevation angle adjustment is required again, the hydraulic rod 17 must first be extended so that its upper end moves back to the upper end of the arc groove. Then, the pull rod 44 is pulled to pull the connecting block 43 out of the connecting groove 45 of the rotating ring 41, so that the support rod 15 is disconnected from the rotating ring 41. At this time, the hydraulic rod 17 can once again take over the drive adjustment of the elevation angle of the mirror chamber mechanism 18.

[0040] The working principle of this invention is as follows: When adjusting the orientation of the plane mirror, the electric actuator 21 first pushes the lifting platform 22, motor A23, and drive block 25 downwards, causing the drive block 25 to insert into the drive groove 36 in the middle of the large gear 34. At this time, the motor A23 starts, driving the drive block 25 to rotate through the rotating shaft 24. The drive block 25 then drives the large gear 34 to rotate synchronously. The rotation of the large gear 34 drives the small gear ring 31 and the mounting column 12 to rotate rapidly, thereby achieving a wide range of rapid adjustments to the orientation of the mirror chamber mechanism 18. When a small-angle precise fine adjustment is required, the electric actuator 21 drives the lifting platform 22 to rise, driving the motor A23 and drive block 25 to move upwards, causing the drive block 25 to disengage from the drive groove 36 of the large gear 34 and insert into the drive groove 36 in the middle of the small gear 35. At this time, motor A23 starts again, and drive block 25 drives pinion 35 to rotate. Pinion 35 meshes with the large gear ring 32 on the outer ring of mounting column 12. Since pinion 35 has fewer teeth than large gear ring 32, the rotation of pinion 35 will drive large gear ring 32 and mounting column 12 to rotate at a slower speed and with more precise accuracy, thereby achieving a small-range precise fine adjustment of the orientation of mirror chamber mechanism 18. When it is necessary to adjust the elevation angle, hydraulic rod 17 will push push frame 16 and support rod 15 to rotate, thereby driving mirror chamber mechanism 18 to rotate synchronously, achieving a preliminary and larger-range adjustment of the elevation angle of mirror chamber mechanism 18. After the preliminary adjustment is completed, the operator can observe the relative position of connecting block 43 and connecting groove 45 on rotating ring 41 through the viewing window on the outside of support frame 14. After confirming the alignment, push the pull rod 44, causing the connecting block 43 to move along the guide groove 42 towards the rotating ring 41 until the connecting block 43 is fully inserted into the connecting groove 45 of the inner ring of the rotating ring 41. Then, the motor B55 drives the sprocket 56 to rotate, and the sprocket 56 drives the transmission rod 57 to rotate via the chain A58. The transmission rod 57 drives the lead screw 54 to rotate synchronously via the chain B59. The lead screw 54 then drives the slider 53 to slide, causing the extension rod 52 and the rotating rod 51 to rotate. The rotating rod 51 then drives the rotating ring 41 to rotate, and the rotating ring 41 drives the support rod 15 to rotate via the connecting block 43, thus making a small angle adjustment to the elevation of the mirror chamber mechanism 18.
