Description

Technical Field

[0001] This application relates to the field of ring light source technology, and in particular to a highly applicable ring light source mounting structure and its usage method. Background Technology

[0002] As a specially designed light source, the ring light source consists of a high-density LED array, which can provide uniform and stable illumination. Through precise optical structure design, it can highlight the three-dimensional information of the illuminated object, reduce the shadow problem caused by multi-directional illumination, and thus capture high-quality images, thus playing an important role.

[0003] A ring-shaped light source exists in the prior art, comprising a ring-shaped housing, a PCB board, and several light-emitting sources. The PCB board is disposed within the cavity of the ring-shaped housing and is fixedly connected to the ring-shaped housing. The sidewalls of the PCB board are inclined and ring-shaped. Several light-emitting sources are mounted on the PCB board. In use, the PCB board provides power and signal control to the light-emitting sources, thereby causing the light-emitting sources to emit light at a specific angle.

[0004] Regarding the aforementioned technologies, since the PCB board is fixedly connected to the annular shell in the existing technology, and the side wall tilt angle of the PCB board is fixed, when it is necessary to adjust the illumination angle of the annular light source, the relevant personnel need to disassemble the annular light source and replace it with a new annular light source with a PCB board having a different tilt angle. This increases the replacement cost and therefore needs to be improved. Summary of the Invention

[0005] To reduce the replacement cost when adjusting the illumination angle of the ring light source, this application provides a highly applicable ring light source mounting structure and its usage method.

[0006] Firstly, this application provides a highly applicable ring light source mounting structure, which adopts the following technical solution: A highly adaptable ring light source mounting structure includes a ring housing and a PCB board. The inner wall of the ring housing is provided with a plurality of positioning grooves, which are distributed along the axial direction of the ring housing. The ring housing is also provided with a positioning ring and a fixing ring. One end of the PCB board abuts against the inner wall of a corresponding positioning groove, and the other end abuts against one side of the positioning ring. The positioning ring is disposed on the fixing ring, and the fixing ring is detachably connected to the ring housing.

[0007] By adopting the above technical solution, compared with the prior art, which requires personnel to disassemble the ring light source and replace it with a new ring light source with a PCB board of different tilt angles in order to adjust the illumination angle of the ring light source, thus increasing the replacement cost, this application, through the setting of positioning ring and fixing ring, allows personnel to simply disassemble the fixing ring and positioning ring when it is necessary to adjust the illumination angle of the ring light source. Then, select PCB boards of different tilt angles and positioning rings of different thicknesses, place the replaced PCB board and positioning ring inside the ring housing, and ensure that one end of the PCB board abuts against the inner wall of the corresponding positioning groove and the other end abuts against the positioning ring. Then, install the fixing ring on the ring housing to replace the PCB board, thus eliminating the need to replace the entire ring light source and effectively saving replacement costs.

[0008] Preferably, the positioning ring is slidably connected to the annular housing, and the sliding direction is the axial direction of the annular housing. The annular housing is also provided with an adjustment mechanism, which includes an adjustment component and a locking component. The adjustment component is used to push the positioning ring to slide, and the locking component is used to lock the positioning ring after it has slid.

[0009] By adopting the above technical solution and setting the adjustment mechanism, relevant personnel can drive the positioning ring to slide through the adjustment component, so that the positioning ring can abut against the replaced PCB board and be locked by the locking component after abutting. This eliminates the need to replace the positioning ring with another specification, effectively saving replacement costs and making replacement more convenient for relevant personnel.

[0010] Preferably, the adjusting assembly includes an adjusting frame that is slidably connected to the annular housing and slides in the same direction as the positioning ring. One end of the adjusting frame abuts against the end of the positioning ring near the fixed ring. The locking assembly is used to lock the adjusting frame after it has slid.

[0011] By adopting the above technical solution, the adjustment frame is designed to abut against the positioning ring and push the positioning ring to slide, thereby abutting the positioning ring against the PCB board and fixing the PCB board together with the inner wall of the positioning groove. This effectively facilitates the adjustment of the positioning ring position by relevant personnel, thus facilitating the replacement of the PCB board.

[0012] Preferably, the locking components are provided in a plurality of form, which are distributed along the axis of the annular housing. Each locking component includes a locking frame and an elastic element. Each locking frame is slidably connected to the annular housing, and the sliding direction is perpendicular to the sliding direction of the adjusting frame. The side of one locking frame near the fixed ring abuts against the side of the adjusting frame away from the fixed ring.

[0013] By adopting the above technical solution and setting the locking component, when the adjusting frame slides to the designated position, the corresponding locking frame can abut against the side of the adjusting frame away from the abutment component, thereby preventing the locking frame from sliding away from the PCB board, thus locking the adjusting frame. By locking the adjusting frame, the positioning ring is also locked, which effectively facilitates the operation of relevant personnel.

[0014] Preferably, the adjustment assembly further includes an unlocking bracket, which is slidably connected to the adjustment bracket and slides in a direction perpendicular to the sliding direction of the locking bracket. The locking bracket locks the adjustment bracket by abutting against the unlocking bracket. An unlocking slot is provided through one side of the unlocking bracket, which is used to correspond to the locking bracket after the unlocking bracket slides, so that the corresponding locking bracket can pass through.

[0015] By adopting the above technical solution, the setting of the unlocking frame allows the locking frame to abut against the unlocking frame, thereby preventing the sliding of the adjusting frame and locking the adjusting frame. At the same time, the existence of the unlocking groove allows the unlocking groove to gradually move to the position corresponding to the locking frame when the unlocking frame slides relative to the adjusting frame. This allows the locking frame to unlock the unlocking frame and the adjusting frame through the unlocking groove, effectively facilitating the unlocking of the unlocking frame by relevant personnel.

[0016] Preferably, one end of the adjusting frame extends out of the annular housing, and a protective cover is also provided outside the annular housing. The end of the adjusting frame extending out of the annular housing is located inside the protective cover, and the protective cover is fitted over the annular housing and rotatably connected to the annular housing.

[0017] By adopting the above technical solution, the protective cover can protect the adjustment frame, thereby reducing the probability of damage to the end of the adjustment frame extending out of the annular shell, effectively ensuring the service life of the adjustment frame. At the same time, after the protective cover is rotated, the adjustment frame can be exposed outside the protective cover, allowing relevant personnel to move the adjustment frame normally.

[0018] Preferably, the adjustment mechanism further includes a drive assembly, which includes a connecting frame and a sliding frame. One end of the connecting frame is rotatably connected to the sliding frame, and the other end is rotatably connected to the protective cover. The sliding frame is slidably connected to the annular housing, and the sliding direction is the same as the sliding direction of the unlocking frame. The unlocking frame is located on the sliding path of the sliding frame.

[0019] By adopting the above technical solution and configuring the drive component, when the protective cover rotates, the protective cover can drive one end of the connecting frame to move together, and cause that end to rotate relative to the protective cover. This, in turn, causes the other end of the connecting frame to move, thereby causing the sliding frame to slide and gradually come into contact with the unlocking frame, pushing the unlocking frame to slide and thus driving the unlocking frame, effectively facilitating the operation of relevant personnel.

[0020] Preferably, a limiting mechanism is also provided inside the annular housing. The limiting mechanism includes a limiting frame and a linkage component. The limiting frame is slidably connected to the annular housing, and the sliding direction is the axial direction of the annular housing. Several limiting parts extend from the limiting frame, and the limiting parts correspond to the locking component. One of the limiting parts is inserted into the unlocking groove. The sliding frame drives the limiting frame to slide through the linkage component, so that the limiting part disengages from the unlocking groove.

[0021] By adopting the above technical solution and setting the limiting mechanism, the limiting frame can be inserted into the unlocking slot, thereby preventing the unlocking frame from slipping due to accidents. This effectively ensures that the locking component locks the unlocking frame. At the same time, when the protective cover rotates, the protective cover can drive the limiting frame to slide through the sliding frame and the linkage component, thereby releasing the limiting of the unlocking frame and realizing the linkage between the sliding frame and the protective cover, which effectively facilitates the operation of relevant personnel.

[0022] Preferably, the linkage assembly includes a linkage gear and two linkage racks, one of which is connected to the sliding frame and the other is connected to the limiting frame. Each linkage rack meshes with the linkage gear, and the linkage gear is rotatably connected to the annular housing.

[0023] By adopting the above technical solution and specifically setting the linkage components, the sliding frame can drive the linkage gear to rotate through the linkage rack during sliding, thereby causing another linkage rack to slide, thus driving the sliding of the limit frame and realizing the linkage between the sliding frame and the limit frame, which effectively facilitates the operation of relevant personnel.

[0024] On the other hand, this application also provides a method for using a highly applicable ring light source mounting structure, which includes the following steps: Placing the PCB board: After selecting a PCB board of appropriate size and specifications, place the PCB board into the cavity of the annular shell; Positioning the PCB board: Place one end of the PCB board into the corresponding positioning groove and abut against the inner wall of the corresponding positioning groove, and then make the other end of the PCB board abut against the inner wall of the annular shell. Place the positioning ring: Select a positioning ring of appropriate thickness and fit it into the cavity of the annular shell so that one side of the positioning ring abuts against the end of the PCB board, thereby positioning the PCB board. Mounting retaining ring: The retaining ring is installed at the end of the annular housing using a connector, so that the retaining ring abuts against the positioning ring, thereby fixing the positioning ring to the PCB board.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The design of the positioning ring and the fixing ring allows personnel to simply remove the fixing ring and the positioning ring when it is necessary to adjust the illumination angle of the ring light source. Then, they can select PCB boards with different tilt angles and positioning rings with different thicknesses, place the replaced PCB boards and positioning rings inside the ring housing, and ensure that one end of the PCB board abuts against the inner wall of the corresponding positioning groove and the other end abuts against the positioning ring. Finally, the fixing ring is installed on the ring housing, which can replace the PCB board without replacing the entire ring light source, effectively saving replacement costs. 2. The adjustment mechanism allows personnel to slide the positioning ring by adjusting the components, so that the positioning ring can abut against the replaced PCB board and be locked by the locking components after abutment. This eliminates the need to replace the positioning ring with another size, effectively saving replacement costs and making replacement easier for relevant personnel. 3. The setting of the limiting mechanism allows the limiting frame to be inserted into the unlocking slot, thereby preventing the unlocking frame from slipping due to accidents. This effectively ensures that the locking component locks the unlocking frame. At the same time, when the protective cover rotates, the protective cover can drive the limiting frame to slide through the sliding frame and the linkage component, thereby releasing the limiting of the unlocking frame and realizing the linkage between the sliding frame and the protective cover, which effectively facilitates the operation of relevant personnel.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] Example 1: Embodiment 1 of this application discloses a highly applicable ring light source mounting structure. (Refer to...) Figure 1 and Figure 2 The highly adaptable ring light source mounting structure includes a ring-shaped housing 1 and a PCB board 2. Several positioning grooves 11 are formed on the inner wall of the ring-shaped housing 1, distributed along the axial direction of the ring-shaped housing 1. A positioning ring 3 and a fixing ring 4 are also provided on the ring-shaped housing 1. One end of the PCB board 2 abuts against the inner wall of a corresponding positioning groove 11, and the other end abuts against one side of the positioning ring 3. The positioning ring 3 is mounted on the fixing ring 4, and the fixing ring 4 is detachably connected to the ring-shaped housing 1.

[0034] Reference Figure 1 and Figure 2 In this embodiment, each positioning groove 11 is a circular groove and is coaxially arranged with the annular housing 1. Each positioning groove 11 is formed on the inner wall of the annular housing 1 facing the fixing ring 4. The positioning grooves 11 are connected to each other, so that the positioning grooves 11 are stepped, and the diameter of the positioning grooves 11 closer to the axis of the annular housing 1 is larger, so that the end of the PCB board 2 can smoothly abut against the inner wall of the positioning groove 11.

[0035] Referring to the figure, the PCB board 2 is an inclined annular shape. The end of the PCB board 2 with a smaller inner diameter along its own axis abuts against the inner wall of the corresponding positioning groove 11 at an angle, thereby increasing the stability of the PCB board 2. The other end of the PCB board 2 abuts against one side of the positioning ring 3, and the outer wall of the positioning ring 3 is attached to the inner wall of the annular housing 1. In this embodiment, one annular housing 1 can accommodate PCB boards 2 with various inclination angles and positioning rings 3 with various thicknesses, thus facilitating replacement by relevant personnel.

[0036] Reference Figure 1 and Figure 2 The positioning ring 3, with its side away from the PCB board 2, is coplanar with the end of the annular housing 1. The fixing ring 4 is located on the side of the positioning ring 3 away from the PCB board 2, and both the side of the positioning ring 3 away from the PCB board 2 and the end of the annular housing 1 abut against the side of the fixing ring 4, thereby fixing the positioning ring 3. The fixing ring 4 is detachably connected to the annular housing 1 by several screws, facilitating disassembly and installation by relevant personnel.

[0037] The implementation principle of the highly applicable ring light source mounting structure in Embodiment 1 of this application is as follows: When it is necessary to replace the PCB board 2, first remove the fixing ring 4, and then remove the positioning ring 3 from the PCB board 2. Next, place one end of the PCB board 2 to be replaced into the corresponding positioning groove 11, so that the end of the PCB board 2 abuts against the angle between it and the positioning groove 11, and then abut the other end of the PCB board 2 against the inner sidewall of the ring shell 1.

[0038] Next, select a positioning ring 3 of appropriate thickness, and align one side of the positioning ring 3 with the end of the PCB board 2, ensuring that the other end of the positioning ring 3 is coplanar with the end of the annular housing 1. Finally, install the fixing ring 4 onto the end of the annular housing 1 using screws, ensuring that the fixing ring 4 is in contact with the end of the positioning ring 3, thus completing the replacement.

[0039] Embodiment 1 of this application also provides a method for using a highly applicable ring light source mounting structure, comprising the following steps: S1. Place the PCB board: After selecting a PCB board 2 of appropriate size and specifications, place the PCB board 2 into the cavity of the annular shell 1. S2. Positioning PCB board: Place one end of PCB board 2 into the corresponding positioning groove 11 and abut against the inner wall of the corresponding positioning groove 11, and then make the other end of PCB board 2 abut against the inner side wall of the annular shell 1. S3. Place the positioning ring: Select a positioning ring 3 of appropriate thickness and place the positioning ring 3 into the cavity of the annular housing 1, so that one side of the positioning ring 3 abuts against the end of the PCB board 2, and the other side of the positioning ring 3 is flush with the end of the annular housing 1, thereby positioning the PCB board 2. S4. Install the fixing ring: Install the fixing ring 4 at the end of the annular housing 1 with several screws, so that the fixing ring 4 is in contact with the positioning ring 3, thereby fixing the positioning ring 3 to the PCB board 2.

[0040] Example 2: The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 3 and Figure 4The outer side of the positioning ring 3 also extends outward with several sliding portions 31, which are distributed at equal angles around the circumference along the axial direction of the positioning ring 3. The end of each sliding portion 31 is embedded in the inner wall of the annular shell 1 and is slidably connected to the annular shell 1, and the sliding direction is the axial direction of the annular shell 1.

[0041] Reference Figure 3 and Figure 4 The annular housing 1 is also provided with an adjustment mechanism 5, which includes an abutment component 51, an adjustment component 52, and a locking component 53. In this embodiment, several abutment components 51 are provided, each corresponding to a sliding part 31. Each abutment component 51 includes a guide rod 511 and an abutment spring 512, and one end of each guide rod 511 is fixedly connected to the inner wall of the annular housing 1. The axial direction of each guide rod 511 is the sliding direction of the positioning ring 3.

[0042] Referring to Figure 4, the other end of each guide rod 511 passes through the corresponding sliding part 31 and is slidably connected to the corresponding sliding part 31. Each sliding part 31 has a through groove for the corresponding guide rod 511 to pass through. Each abutment spring 512 is sleeved on the corresponding guide rod 511. Each abutment spring 512 is located on the side of the positioning ring 3 away from the fixing ring 4, and one end of each abuts against the inner wall of the annular housing 1, while the other end abuts against the corresponding sliding part 31. This allows the positioning ring 3 to return to its initial position under the elastic force of the abutment spring 512, thus facilitating disassembly by relevant personnel.

[0043] Reference Figure 4 and Figure 5 In this embodiment, the number of adjustment components 52 is set to two, and the two adjustment components 52 are respectively located on opposite sides of the positioning ring 3. Each adjustment component 52 includes an adjustment frame 521, an unlocking frame 522 and a reset spring 523. Each adjustment frame 521 is located on the side of the corresponding sliding part 31 away from the abutting spring 512, and is slidably connected to the inner wall of the annular housing 1, and the sliding direction is the axial direction of the annular housing 1.

[0044] Reference Figure 3 and Figure 4 Each adjusting bracket 521 abuts against a corresponding sliding part 31, so that the adjusting bracket 521 can push the positioning ring 3 to slide. In this embodiment, the end of the adjusting bracket 521 that abuts against the sliding part 31 is "T"-shaped and abuts against the inner wall of the annular shell 1 to constrain the adjusting bracket 521, so that the adjusting bracket 521 can only move along the axial direction of the annular shell 1.

[0045] Reference Figure 3 and Figure 5One end of each adjustment bracket 521 extends out of the annular housing 1, allowing personnel to change the position of the positioning ring 3 by moving the adjustment bracket 521. One end of each unlocking bracket 522 extends into the corresponding adjustment bracket 521 and is slidably connected to the corresponding adjustment bracket 521, with the sliding direction being the length direction of the corresponding adjustment bracket 521.

[0046] Reference Figure 4 and Figure 5 Each reset spring 523 is sleeved on the corresponding adjusting bracket 521 and is located on the side of the corresponding unlocking bracket 522 away from the positioning ring 3. One end of each reset spring 523 abuts against the side of the corresponding unlocking bracket 522 near the positioning ring 3, and the other end abuts against the side wall of the corresponding adjusting bracket 521, so that the reset spring 523 can reset the unlocking bracket 522.

[0047] Reference Figure 4 and Figure 5 Each unlocking bracket 522 has an unlocking slot 6 extending through both sides of its top edge along its width. Several groups of locking components 53 are arranged, equidistantly along the sliding direction of the adjusting bracket 521, so that the locking components 53 can lock the unlocking bracket 522 at multiple locations, thus locking the unlocking bracket 522 and the adjusting bracket 521 in multiple positions. Each group contains two locking components 53, located on either side of the unlocking bracket 522 along its width.

[0048] Reference Figure 4 Each locking assembly 53 includes a locking frame 531 and an elastic element 532. The locking frames 531 are all correspondingly arranged with the unlocking slots 6, and the locking frames 531 are all located on the side of the corresponding unlocking slot 6 away from the adjusting frame 521. One locking frame 531 is located below the unlocking frame 522, and its top wall abuts against the bottom wall of the unlocking frame 522, thereby locking the unlocking frame 522 and the adjusting frame 521.

[0049] Reference Figure 3 and Figure 4 In this embodiment, the elastic element 532 is configured as a pressure spring. Each pressure spring is sleeved on the end of the corresponding locking frame 531 away from the unlocking frame 522, and one end of each spring abuts against the corresponding locking frame 531, while the other end abuts against the inner wall of the annular housing 1, so as to reset the locking frame 531 by its own elastic force.

[0050] Reference Figure 3 and Figure 4Two protective covers 7 are also provided outside the annular housing 1. The two protective covers 7 are correspondingly arranged with the unlocking brackets 522, and each unlocking bracket 522 is located inside the corresponding protective cover 7. One end of each protective cover 7 is embedded in the outer wall of the annular housing 1 and is rotatably connected to the annular housing 1. An opening is provided on one side wall of each protective cover 7 so that the unlocking bracket 522 can be exposed outside the protective cover 7 after the protective cover 7 is slid.

[0051] Reference Figure 4 The adjustment mechanism 5 also includes a drive assembly 54, the number of which is set to two, and each drive assembly 54 is corresponding to a protective cover 7. Each drive assembly 54 includes a connecting frame 541 and a sliding frame 542. In this embodiment, each drive assembly 54 has two connecting frames 541, and the two connecting frames 541 are located at both ends of the protective cover 7 along its length.

[0052] Reference Figure 3 and Figure 4 One end of each connecting frame 541 is rotatably connected to the corresponding protective cover 7 via a pin, and the other end of each connecting frame 541 is rotatably connected to the corresponding sliding frame 542 via a pin. Each sliding frame 542 is located inside the annular housing 1 and is slidably connected to the corresponding annular housing 1, and the sliding direction is the same as the sliding direction of the corresponding unlocking frame 522.

[0053] Reference Figure 4 and Figure 5 Each unlocking bracket 522 has an outwardly extending abutment portion 5221, and each abutment portion 5221 is integrally formed with the unlocking bracket 522. Each abutment portion 5221 is located on the side of the sliding bracket 542 away from the positioning ring 3, and is located on the sliding path of the corresponding sliding bracket 542, so that when the sliding bracket 542 abuts against the abutment portion 5221 during the sliding process, it can push the unlocking bracket 522 to slide, thereby causing the unlocking groove 6 on the unlocking bracket 522 to move to directly above the corresponding locking bracket 531, so that the locking bracket 531 can unlock the unlocking bracket 522 through the unlocking groove 6.

[0054] Reference Figure 4 and Figure 5 In the initial state, the unlocking bracket 522 is located inside the protective cover 7. At this time, the locking bracket 531 abuts against the unlocking bracket 522, thereby locking the unlocking bracket 522. The sliding bracket 542 is also located abutting against the unlocking bracket 522. When the protective cover 7 rotates, the protective cover 7 drives the connecting bracket 541 to move together, thereby causing the connecting bracket 541 to drive the sliding bracket 542 to slide, so that the sliding bracket 542 gradually moves closer to the abutment part 5221.

[0055] Reference Figure 4 and Figure 5When the sliding bracket 542 abuts against the abutment part 5221, thereby pushing the unlocking bracket 522 to slide, the unlocking groove 6 on the unlocking bracket 522 gradually moves to directly above the corresponding locking bracket 531, so that the locking bracket 531 can unlock the unlocking bracket 522 through the unlocking groove 6. During this process, the return spring 523 is gradually compressed, thereby storing elastic potential energy.

[0056] Reference Figure 3 and Figure 4 The annular housing 1 is also provided with a limiting mechanism 8. In this embodiment, the number of limiting mechanisms 8 is set to two, and they are arranged one-to-one with the sliding frame 542. Each limiting mechanism 8 includes a limiting frame 81 and a linkage component 82. Each limiting frame 81 is slidably connected to the inner wall of the annular housing 1, and the sliding direction is the axial direction of the annular housing 1.

[0057] Reference Figure 4 and Figure 5 Each limiting frame 81 extends outward with several limiting portions 811, and each limiting portion 811 corresponds to one of several sets of locking components 53. Each limiting portion 811 is integrally formed with the corresponding limiting frame 81, and the end of each limiting portion 811 away from the limiting frame 81 is bent downward. One of the limiting portions 811 extends downward into one of the unlocking slots 6 on the unlocking frame 522 to limit the unlocking frame 522 and prevent the unlocking frame 522 from sliding.

[0058] Reference Figure 3 , Figure 4 and Figure 5 Each linkage component 82 includes a linkage gear 821 and two linkage racks 822. One linkage rack 822 is fixedly connected to the corresponding sliding frame 542, and the other linkage rack 822 is fixedly connected to the corresponding limiting frame 81. Each linkage gear 821 is rotatably connected to the annular housing 1 via a pin, and each linkage gear 821 is located between the corresponding two linkage racks 822. Both linkage racks 822 mesh with the corresponding linkage gear 821 to achieve linkage between the sliding frame 542 and the limiting frame 81.

[0059] Reference Figure 4 and Figure 5 In the initial state, when the unlocking bracket 522 is inside the protective cover 7, the corresponding limiting part 811 on the limiting bracket 81 is inserted into the corresponding unlocking slot 6. When the protective cover 7 starts to rotate, the protective cover 7 drives the corresponding sliding bracket 542 to slide through the connecting bracket 541, thereby causing the sliding bracket 542 to drive the corresponding limiting bracket 81 to slide through the linkage rack 822 and the linkage gear 821, and thus causing the limiting part 811 on the limiting bracket 81 to gradually disengage from the unlocking slot 6.

[0060] Reference Figure 3, Figure 4 and Figure 5 When the limiting part 811 is completely disengaged from the unlocking groove 6, the sliding frame 542 gradually abuts against the abutting part 5221 on the unlocking frame 522, thereby pushing the abutting part 5221 to move and causing the unlocking frame 522 to slide. This causes the unlocking groove 6 on the unlocking frame 522 to gradually move directly above the corresponding locking frame 531, thus unlocking the unlocking frame 522 and the adjusting frame 521. At this time, the unlocking frame 522 is not on the sliding path of the limiting part 811. Subsequently, under the elastic force of the abutting spring 512, the positioning ring 3 pushes the adjusting frame 521 and the unlocking frame 522 to slide together, thereby causing the positioning ring 3, the adjusting frame 521, and the unlocking frame 522 to disengage from the annular housing 1.

[0061] The implementation principle of the highly applicable ring light source mounting structure in Embodiment 2 of this application is as follows: When it is necessary to disassemble the PCB board 2, the protective cover 7 is pushed to rotate. The protective cover 7 drives the corresponding sliding frame 542 to slide through the connecting frame 541. As a result, the sliding frame 542 drives the corresponding limiting frame 81 to slide through the linkage rack 822 and the linkage gear 821, thereby causing the limiting part 811 on the limiting frame 81 to gradually disengage from the unlocking groove 6.

[0062] After the limiting part 811 is completely disengaged from the unlocking groove 6, the sliding bracket 542 gradually abuts against the abutting part 5221 on the unlocking bracket 522, thereby pushing the abutting part 5221 to move and causing the unlocking bracket 522 to slide. This causes the unlocking groove 6 on the unlocking bracket 522 to gradually move directly above the corresponding locking bracket 531, thus unlocking the unlocking bracket 522 and the adjusting bracket 521. At this time, the unlocking bracket 522 is completely displaced to one side of the limiting part 811. Subsequently, under the elastic force of the abutting spring 512, the positioning ring 3 pushes the adjusting bracket 521 and the unlocking bracket 522 to slide together, thereby causing the positioning ring 3, the adjusting bracket 521, and the unlocking bracket 522 to disengage from the annular housing 1.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
