Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a quick-release device for optical accessories. Background Technology

[0002] In the field of modern lighting, to meet the refined lighting requirements of different scenarios such as stage lighting, film and television shooting, industrial lighting, and medical lighting, luminaires typically need to be equipped with optical accessories such as light shields, lenses, filters, gratings, or diffusers. These optical accessories can change the direction of light propagation, intensity distribution, and color characteristics, thereby achieving different lighting effects. For example, in stage performances, filters can create specific atmospheres and colors for the scene; in industrial inspection, lenses can focus light to improve the accuracy of inspection.

[0003] However, in related technologies, the connection between optical accessories and the lamp body mostly adopts traditional methods such as screw fixing and snap-fit. When using screw fixing, installing and removing optical accessories requires tools such as screwdrivers, which is cumbersome and time-consuming, especially in scenarios where optical accessories need to be frequently replaced, greatly reducing work efficiency. Although the snap-fit ​​method is relatively simpler to operate, it may loosen or even fall off during use, affecting the lighting effect and safety. Utility Model Content

[0038] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0039] See Figure 1 and Figure 2 This utility model discloses a quick-release device for optical accessories, which includes a lamp body 10, an optical accessory 30, and a locking member 40; for details, please refer to [reference needed]. Figure 3 and Figure 5The lamp body 10 is provided with a mounting base 20, and the mounting base 20 is provided with a first connecting part 21. (See reference...) Figure 6 The optical accessory 30 is provided with a second connecting part 31, and the second connecting part 31 is detachably connected to the first connecting part 21; wherein, the second connecting part 31 is provided with a first locking part 32.

[0040] See Figure 4 The aforementioned locking member 40 is rotatably connected to the lamp body 10, and the locking member 40 is provided with a second locking part 41. (See reference...) Figure 1 as well as Figure 7 The second locking part 41 is used to connect with the first locking part 32 after the second connecting part 3131 is connected with the first connecting part 2121.

[0041] Based on this structure, when using the quick-release device for optical accessories of this utility model, when installing the optical accessory 30, the second connecting part 31 of the optical accessory 30 can be aligned with the first connecting part 21 of the lamp body 10 mounting base 20, and the optical accessory 30 can be pushed to make the first connecting part 21 and the second connecting part 31 detachably connected, thus completing the initial connection and positioning of the optical accessory 30 and the lamp body 10.

[0042] Then, the locking member 40 is manually rotated. The locking member 40 rotates around its connection point with the lamp body 10. During rotation, the second locking part 41 on the locking member 40 gradually approaches the first locking part 32 on the second connecting part 31 of the optical accessory 30. When the second locking part 41 moves to contact the first locking part 32 and reaches a predetermined position, the second locking part 41 and the first locking part 32 cooperate to achieve locking. At this time, the connection between the first connecting part 21 and the second connecting part 31 is locked, and the two cannot be separated.

[0043] During operation, the optical accessory 30 is securely fixed to the lamp body 10 because the second locking part 41 of the locking member 40 and the first locking part 32 of the optical accessory 30 are in a locked connection. Even if the device is subjected to vibration, shaking, or external force during use, this locking structure ensures that the optical accessory 30 will not loosen or fall off, thereby ensuring that the optical accessory 30 can stably perform its functions of changing the direction of light propagation, intensity distribution, and color characteristics, providing a stable and reliable lighting effect for different scenarios.

[0044] When it is necessary to disassemble or replace the optical accessory 30, the locking member 40 can be rotated in the reverse direction, so that the second locking part 41 on the locking member 40 gradually moves away from the first locking part 32 on the second connecting part 31 of the optical accessory 30 until the two are completely separated, thus completing the unlocking operation. At this time, the second connecting part 31 of the optical accessory 30 is detachable from the first connecting part 21 of the lamp body 10 mounting base 20. After unlocking, the optical accessory 30 can be pulled to remove it from the lamp body 10.

[0045] In this way, no tools are needed during the installation or removal of the optical accessory 30, making the operation simple and quick, and enabling rapid replacement of the optical accessory 30 to meet the needs of frequent replacement of the optical accessory 30 in different scenarios. Compared with the traditional screw fixing method, the quick-release device for optical accessories of this utility model greatly saves installation time, improves work efficiency, and ensures the firmness and stability of the installation of the optical accessory 30.

[0046] Therefore, this utility model enables the optical accessory 30 to be installed and disassembled quickly, conveniently, and stably, effectively solving the problems of cumbersome operation and unstable installation in traditional connection methods, and greatly improving the convenience and reliability of using the optical accessory 30 in different scenarios.

[0047] The lamp body 10 can be a lighting lamp, photographic lamp, etc., and the optical accessory 30 can be a lens, light shield, diffuser, or filter, etc. After the optical accessory 30 is connected to the lamp body 10, it is positioned in the direction of light illumination from the lamp body 10. Furthermore, the detachable connection between the first connecting part 21 of the lamp body 10 and the second connecting part 31 of the optical accessory 30 provides initial positioning and connection for the installation of the optical accessory 30, ensuring that the optical accessory 30 will not arbitrarily detach from the lamp body 10 before subsequent locking operations.

[0048] As an optional implementation method, see [link / reference]. Figure 2 as well as Figure 3 The lamp body 10 has a boss 11, and the mounting base 20 is detachably mounted on the boss 11. (See reference) Figure 5 The first connecting part 21 is disposed on the outer peripheral wall of the mounting base 20. (See reference...) Figure 4 The locking member 40 is rotatably connected to the outer periphery of the boss 11 and the mounting base 20, and the second locking part 41 includes a receiving groove 42, which is used to receive the first locking part 32 after the first connecting part 21 and the second connecting part 31 are connected.

[0049] Based on this structure, when installing the optical accessory 30, the second connecting part 31 of the optical accessory 30 can be aligned with the first connecting part 21 on the outer peripheral wall of the mounting base 20, and the optical accessory 30 can be pushed to complete the detachable connection between the two, realizing the initial connection between the optical accessory 30 and the lamp body 10. Furthermore, while the second connecting part 31 is connected to the first connecting part 21, the first locking part 32 on the second connecting part 31 also extends into the receiving groove 42 of the locking member 40.

[0050] Next, the locking member 40 is rotated, causing the receiving groove 42 to rotate relative to the first locking part 32. At the same time, the second locking part 41 on the receiving groove 42 gradually approaches the first locking part 32 and locks into it. At this time, the receiving groove 42 not only provides a place for the first locking part 32, but also the second locking part 41 provided in the receiving groove 42 cooperates with the first locking part 32 to complete the locking operation.

[0051] The second locking part 41 and the first locking part 32 can be magnetic or snap-fit ​​structures. When the first locking part 32 enters the receiving groove 42 and the locking member 40 rotates, the two parts approach each other and are tightly attracted by magnetic force or connected by snap-fit ​​structure, thereby firmly fixing the optical accessory 30 to the lamp body 10. This installation method does not require complicated tools and can be completed by simple alignment, pushing and rotating operations, which greatly improves installation efficiency.

[0052] See Figure 3 Since the locking element 40 is located radially outward of the mounting base 20, the receiving groove 42 and the first connecting portion 21 are also radially distributed. (See reference...) Figure 6 The first locking part 32 is disposed on the radially outer side of the second connecting part 31 along the optical accessory 30. (See again...) Figure 1 In this way, when the second connecting part 31 is connected to the first connecting part 21, the first locking part 32 can also be installed into the receiving groove 42 at the same time.

[0053] It should be noted that the second connecting part 31 is sized to match the first connecting part 21, and the two can be inserted along the axial direction of the mounting base 20. After insertion, the second connecting part 31 and the first connecting part 21 are mutually limited along the circumferential direction of the mounting base 20. After the locking member 40 rotates along the circumferential direction of the mounting base 20, it can lock the first locking part 32 on the second connecting part 31. At this time, it can restrict the movement of the second connecting part 31 and the first connecting part 21 in the axial direction of the mounting base 20, which plays a dual role in limiting the optical accessory 30 in the axial and circumferential directions of the mounting base 20, further enhancing the installation stability of the optical accessory 30 and the lamp body 10.

[0054] When the optical accessory 30 needs to be replaced, rotate the locking member 40 in the reverse direction to gradually move the second locking part 41 on the receiving groove 42 away from the first locking part 32 until the two are completely separated, thus releasing the second locking part 41 from locking the first locking part 32. At this time, the second connecting part 31 of the optical accessory 30 and the first connecting part 21 of the mounting base 20 can be disassembled along the axial direction of the mounting base 20. The optical accessory 30 can be gently pulled off the mounting base 20.

[0055] Furthermore, the mounting base 20 is detachably mounted on the boss 11, allowing the mounting base 20 to be replaced or adjusted according to actual needs. For example, when it is necessary to adapt to different specifications of optical accessories 30, this can be achieved by replacing the mounting base 20. In this way, the lamp body 10 of this invention can be compatible with various specifications of optical accessories 30, enhancing the versatility and adaptability of the device.

[0056] As an optional implementation method, see [link / reference]. Figure 2 The locking element 40 includes a connecting ring disk 43 and a plurality of arc-shaped sidewalls 44. Specifically, the plurality of arc-shaped sidewalls 44 are spaced apart along the circumferential direction on the connecting ring disk 43, and the receiving groove 42 is formed between two adjacent arc-shaped sidewalls 44. See reference. Figure 4 The connecting ring disk 43 is arranged around the outer periphery of the boss 11. The outer peripheral wall of the boss 11 is provided with a first rotating part, and the inner peripheral wall of the connecting ring disk 43 is provided with a second rotating part. The second rotating part is rotatably engaged with the first rotating part.

[0057] Based on this structure, after the first locking part 32 on the second connecting part 31 of the optical accessory 30 extends into the receiving groove 42, the locking member 40 can be rotated to lock or unlock. Since the second rotating part of the inner peripheral wall of the connecting ring disk 43 rotates and engages with the first rotating part of the outer peripheral wall of the boss 11, the connecting ring disk 43 can rotate around the boss 11. During the rotation, multiple arc-shaped sidewalls 44 rotate synchronously, and the receiving grooves 42 between adjacent arc-shaped sidewalls 44 also move in a circular motion around the boss 11. At the same time, the second locking part 41 in the receiving groove 42 will move closer to or further away from the first locking part 32, thereby achieving locking or unlocking.

[0058] Therefore, by applying external force to the locking member 40, the locking member 40 can be rotated, thereby achieving the locking or unlocking action, which is convenient to operate.

[0059] As an optional implementation, the second locking part 41 includes a locking protrusion 48, which is disposed at one end of the arcuate sidewall 44 facing the receiving groove 42. A locking gap 46 is formed between the locking protrusion 48 and the connecting ring disc 43. See also... Figure 6 as well as Figure 7 The first locking part 32 includes a locking block, which is used to enter or exit the locking interval 46 during the rotation of the locking member 40.

[0060] Based on this structure, after the locking block extends into the receiving groove 42, during locking, the locking member 40 can be rotated to bring the locking protrusion 48 located at one end of the receiving groove 42 closer to the locking block, and the locking block gradually enters the locking interval 46. (See reference...) Figure 7When the locking block enters the locking interval 46, the locking protrusion 48 abuts against the top surface of the locking block, and the connecting ring 43 abuts against the bottom surface of the locking block, thereby restricting the locking block from disengaging from the locking member 40 axially from the locking interval 46.

[0061] When unlocking, the locking member 40 can be rotated to move the locking interval 46 away from the locking block. The locking block gradually exits the locking interval 46. At this time, the locking block is not limited by the locking protrusion 48 in the axial direction of the locking member 40. The second connecting part 31 can be separated from the first connecting part 21 along the axial direction of the mounting base 20 so that the optical accessory 30 is separated from the lamp body 10.

[0062] Therefore, in the locked state, even if the device is subjected to axial vibration or external force, the locking block is difficult to dislodge from the locking gap 46, which significantly improves the stability of the optical accessory 30 during installation.

[0063] As an optional implementation method, see [link / reference]. Figure 7 The upper end of the locking protrusion 48 is provided with a first pressing surface 47. The first pressing surface 47 is used to guide the locking block into the receiving groove 42 and is pressed by the locking block when the locking block is inserted into the receiving groove 42, so as to drive the locking member 40 to rotate and make the locking interval 46 move away from the locking block.

[0064] See Figure 4 An elastic element 50 is provided between the first rotating part and the second rotating part. Specifically, one end of the elastic element 50 abuts against the first rotating part, and the other end of the elastic element 50 abuts against the second rotating part. The elastic element 50 is used to provide an elastic stress to drive the locking member 40 to rotate and reset, and to bring the locking gap 46 closer to the locking block.

[0065] Based on this structure, when the optical accessory 30 is not installed, the locking member 40 is in the initial position under the elastic stress of the elastic member 50. At this time, the locking protrusion 48 is in the locked position, and the first pressing surface 47 of the locking protrusion 48 is facing outward.

[0066] When installing the optical accessory 30, align the second connecting portion 31 of the optical accessory 30 with the first connecting portion 21 of the lamp body 10 mounting base 20, and push the optical accessory 30 to achieve a detachable connection between the first connecting portion 21 and the second connecting portion 31. Simultaneously, the locking block on the second connecting portion 31 approaches the locking protrusion 48. The locking block first contacts the first pressing surface 47 of the locking protrusion 48. As the locking block moves forward, it slides along the first pressing surface 47 towards the receiving groove 42, generating a pressing force on the first pressing surface 47. This pressing force causes the locking member 40 to rotate against the elastic stress of the elastic member 50, causing the locking gap 46 to gradually move away from the locking position. As the optical accessory 30 continues to advance, the locking block smoothly extends into the receiving groove 42.

[0067] Once the locking block is fully inserted into the receiving groove 42, the locking protrusion 48 is no longer subjected to top pressure, and the locking member 40 quickly rotates and resets under the elastic stress of the elastic member 50, causing the locking gap 46 to reappear close to the first locking part 32. At this time, the locking protrusion 48 and the locking block cooperate with each other to firmly lock the locking block within the locking gap 46, completing the automatic locking of the optical accessory 30.

[0068] Therefore, there is no need to manually rotate the locking part 40; connection and automatic locking can be achieved simply by pushing the optical accessory 30. This makes the operation simpler and faster, greatly improving installation efficiency and reducing the difficulty of operation. Even non-professionals can easily complete the installation of the optical accessory 30.

[0069] When the optical accessory 30 needs to be replaced, manually rotate the locking member 40 to overcome the elastic stress of the elastic member 50, so that the locking gap 46 moves away from the locking block, and the locking block gradually exits the locking gap 46. At this time, the locking block is no longer limited by the locking protrusion 48 in the axial direction of the locking member 40, and the second connecting part 31 can disengage from the first connecting part 21 along the axial direction of the mounting base 20. The locking block exits the receiving groove 42 in the axial direction, and the optical accessory 30 is removed from the lamp body 10.

[0070] After disassembly, the locking member 40 is released, and under the action of the elastic member 50, the locking member 40 automatically rotates back to its initial position, preparing for the next installation of the optical accessory 30. The entire disassembly process is simple to operate, and the reset function of the elastic member 50 ensures that the locking member 40 can quickly return to its initial state, further improving operational efficiency.

[0071] A second pressing surface 34 can be provided on the side of the locking block away from the optical accessory 30, and both the second pressing surface 34 and the first pressing surface 47 are inclined or arc-shaped structures. In this way, when the locking block extends into the receiving groove 42, the second pressing surface 34 on the locking block can press against the first pressing surface 47 of the locking protrusion 48, while the second pressing surface 34 slides relative to the first pressing surface 47. This can both push the locking protrusion 48 to drive the entire locking member 40 to rotate, and allow the locking block to extend into the receiving groove 42 without obstruction.

[0072] As an optional implementation method, see [link / reference]. Figure 2 as well as Figure 5 The mounting base 20 includes a mounting plate 60 and a pressure ring 70. For details, please refer to [link / reference]. Figure 8 The mounting plate 60 is mounted on the boss 11, and the pressure ring 70 is mounted on the outer periphery of the mounting plate 60, and the pressure ring 70 presses against the top of the connecting ring plate 43. The first connecting part 21 is formed on the outer periphery of the pressure ring 70; the arc-shaped sidewall 44 surrounds the outer periphery of the pressure ring 70.

[0073] Based on this structure, during assembly, the locking member 40 can first be sleeved onto the outer periphery of the boss 11 along the axial direction of the boss 11, and rotated with the first rotating part of the outer periphery of the boss 11 through the second rotating part of the inner peripheral wall of the connecting ring disk 43. Then, the mounting plate 60 is installed on the boss 11, and the pressure ring 70 is installed on the outer periphery of the mounting plate 60. At the same time, the pressure ring 70 presses against the top of the connecting ring disk 43. At this time, the two ends of the connecting ring disk 43 of the locking member 40 are respectively pressed by the pressure ring 70 and the lamp body 10.

[0074] Since the first connecting part 21 is formed on the outer periphery of the pressure ring 70, the arc-shaped sidewall 44 surrounds the outer periphery of the pressure ring 70, and a receiving groove 42 is formed between two adjacent arc-shaped sidewalls 44, when the second connecting part 31 on the optical accessory 30 is connected to the first connecting part 21 on the pressure ring 70, the locking block on the second connecting part 31 can simultaneously extend into the receiving groove 42 outside the first connecting part 21.

[0075] Therefore, the pressure ring 70 can limit and fix the connecting ring disk 43, preventing the locking member 40 from shifting axially. Due to the limiting effect of the pressure ring 70 on the connecting ring disk 43, the connecting ring disk 43 can rotate smoothly during rotation without jamming or shifting, making the unlocking operation smoother. The first connecting part 21 is formed on the outer periphery of the pressure ring 70, which facilitates docking with the second connecting part 31 of the optical accessory 30.

[0076] As an optional implementation method, see [link / reference]. Figure 2 The mounting plate 60 includes a base 61 and an annular body 62. Specifically, the base 61 is mounted on the boss 11, and the pressure ring 70 is mounted on the base 61 and surrounds the outer periphery of the annular body 62. The pressure ring 70 is provided with a first connecting hole 71, the base 61 is provided with a second connecting hole 63, and the boss 11 is provided with a third connecting hole 13, and the first connecting hole 71, the second connecting hole 63, and the third connecting hole 13 are all correspondingly provided.

[0077] Based on this structure, during assembly, the base 61 of the mounting plate 60 can be placed on the boss 11, with the second connecting hole 63 of the base 61 aligned with the third connecting hole 13 of the boss 11; then, the pressure ring 70 is fitted around the outer periphery of the annular body 62 and placed on the base 61, with the first connecting hole 71 of the pressure ring 70 aligned with the second connecting hole 63 of the base 61; simultaneously, the bottom outer periphery of the pressure ring 70 is also pressed against the top of the connecting ring plate 43. Then, fasteners such as bolts, screws, or pins are used to pass through the first connecting hole 71, the second connecting hole 63, and the third connecting hole 13 to fix the pressure ring 70, the base 61, and the boss 11 into a whole.

[0078] Thus, the coaxial arrangement and connection of multiple connecting holes achieves precise axial positioning of the pressure ring 70, the base 61 and the boss 11, avoiding jamming of the locking part 40 or misalignment of the optical accessory 30 caused by installation offset.

[0079] The annular body 62 connects the interior of the lamp body 10 with the interior of the optical accessory 30, so that the light inside the lamp body 10 can shine onto the optical accessory 30 through the light-transmitting channel formed by the annular body 62.

[0080] As an optional implementation, the first connecting portion 21 includes a plurality of connecting grooves 211, which are spaced apart along the circumferential direction on the outer peripheral wall of the mounting base 20. Correspondingly, the second connecting portion 31 includes a plurality of connecting arms 311, which are spaced apart along the circumferential direction at the ends of the optical accessory 30. The plurality of connecting arms 311 are connected to the plurality of connecting grooves 211 in a one-to-one correspondence.

[0081] Based on this structure, when installing the optical accessory 30, first bring the optical accessory 30 close to the mounting base 20 of the lamp body 10, so that the multiple connecting arms 311 spaced apart along the circumferential direction at the end of the optical accessory 30 are aligned with the multiple connecting slots 211 spaced apart along the circumferential direction on the outer peripheral wall of the mounting base 20. Then push the optical accessory 30 so that the multiple connecting arms 311 are respectively inserted into the corresponding connecting slots 211.

[0082] After the connecting arm 311 and the connecting groove 211 are fully engaged, the locking member 40 is rotated so that the locking protrusion 48 on the locking member 40 engages with the locking block on the outside of the connecting arm 311, thereby further securing the optical accessory 30 to the mounting base 20.

[0083] Among them, multiple connecting slots 211 and multiple connecting arms 311 can be connected at multiple positions simultaneously. Multiple connection points jointly distribute the force during the locking process, avoiding damage to the connection structure due to excessive force at a single point. At the same time, it also enhances the overall deformation resistance of the optical accessory 30 when subjected to external forces.

[0084] Thus, through the insertion and release structure of the connecting slot 211 and the connecting arm 311, disassembly can be completed without tools after unlocking, facilitating quick replacement of the optical accessory 30 and adapting to diverse lighting needs.

[0085] As an optional implementation method, see [link / reference]. Figure 5 The ends of the two opposite sidewalls of the connecting groove 211 are provided with first guide surfaces 22, see reference. Figure 6 The end of the connecting arm 311 is provided with a second guide surface 33, wherein the first guide surface 22 is used to cooperate with the second guide surface 33 to guide the connecting arm 311 to be inserted into the connecting groove 211.

[0086] Specifically, the first guide surface 22 and the second guide surface 33 can both be inclined surfaces or arc-shaped structures. When the connecting arm 311 approaches the end of the connecting groove 211, the first guide surface 22 of the connecting arm 311 first contacts the second guide surface 33 on the connecting groove 211. When the optical accessory 30 is pushed further, under the action of the thrust, the second guide surface 33 slides along the first guide surface 22, guiding the connecting arm 311 into the connecting groove 211.

[0087] Therefore, even if there is a certain angular or positional deviation between the connecting arm 311 and the connecting groove 211 during initial alignment, the automatic alignment and rapid insertion of the connecting arm 311 and the connecting groove 211 can be achieved through the sliding cooperation of the first guide surface 22 and the second guide surface 33.

[0088] As an optional implementation method, see [link / reference]. Figure 4 The first rotating part includes a plurality of rotating grooves 12, which are spaced apart along the circumferential direction on the outer peripheral wall of the boss 11. The second rotating part includes a plurality of rotating blocks 45, which are spaced apart along the circumferential direction on the inner peripheral wall of the connecting ring disk 43. Each of the rotating blocks 45 is connected to a corresponding rotating groove 12.

[0089] Based on this structure, when installing the locking member 40, the connecting ring disk 43 can be fitted onto the boss 11 of the lamp body 10, so that the multiple rotating blocks 45 spaced circumferentially on the inner peripheral wall of the connecting ring disk 43 are aligned with the multiple rotating grooves 12 spaced circumferentially on the outer peripheral wall of the boss 11. Pushing the connecting ring disk 43 causes the multiple rotating blocks 45 to respectively embed into their corresponding rotating grooves 12. Then, the two ends of the elastic member 50 can be respectively installed on the side walls of the rotating blocks 45 and the rotating grooves 12.

[0090] After the mounting base 20 is installed, the optical accessory 30 can be brought close to the mounting base 20, and the connecting arm 311 on the optical accessory 30 can be aligned with the connecting groove 211 on the outer periphery of the mounting base 20 for insertion. At the same time, the locking block on the outside of the connecting arm 311 will extend into the receiving groove 42, and during the process of the locking block extending into the receiving groove 42, it will press against the first pressing surface 47 on the locking protrusion 48 through the second pressing surface 34, thereby causing the locking protrusion 48 to be stressed and drive the locking member 40 to rotate. When the locking member 40 rotates, it will drive the rotating block 45 to rotate in the rotating groove 12 and compress the elastic member 50.

[0091] After the locking block is fully inserted into the receiving groove 42, since the locking protrusion 48 is no longer under pressure, the elastic element 50 will release elastic potential energy, causing the rotating block 45 to rotate again in the rotating groove 12, and causing the connecting ring disk 43 and its arc-shaped sidewall 44 to rotate. At this time, the locking gap 46 formed between the locking protrusion 48 and the connecting ring disk 43 will approach the locking block and lock the locking block.

[0092] Therefore, during the installation of the connecting arm 311 with the connecting groove 211, the locking protrusion 48 can be pushed from the locked position to the unlocked position. After the connecting arm 311 is installed in place with the connecting groove 211, the locking protrusion 48 can be reset to the locked position and automatically locked under the action of the elastic element 50, avoiding installation errors caused by forgetting to unlock or not locking correctly. This process requires no professional tools or complicated operating skills, greatly reducing installation time. Even non-professionals can quickly complete the installation, making it especially suitable for scenarios such as film and television shooting and stage lighting debugging that require frequent replacement of optical accessories 30.

[0093] When disassembling the optical accessory 30, the locking member 40 can be manually rotated to move the locking gap 46 away from the locking block, thereby unlocking the device. Then the connecting arm 311 can be pulled out of the connecting groove 211. The operation is simple.

[0094] The elastic element 50 can be a spring, a rubber block, a silicone pad, etc. In this embodiment, the elastic element 50 is selected as a spring.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
