Description

Technical Field

[0001] This utility model relates to the field of optical accessory technology, and in particular to an optical accessory connection component. Background Technology

[0002] When using optical accessories such as lamps, video equipment, and cameras, an optical connection accessory structure is generally required to facilitate connection to batteries or other supporting structures (such as bracket structures, selfie stick structures, etc.). This allows the lamps, video equipment, and cameras to be connected to the battery or other supporting structure for use.

[0003] During use, lighting fixtures, video equipment, cameras, etc. need to be adjusted in angle according to different usage requirements. During the angle adjustment process, the rotating arm should be locked after the angle is adjusted to reduce shaking and other issues during use.

[0004] However, in existing technologies, locking or unlocking of the angle-adjustable swing arm typically uses a bolt and nut structure, achieving locking or unlocking during rotation, which is a complex adjustment process. Furthermore, with prolonged use, the threaded structure is prone to loosening, leading to unstable locking. Utility Model Content

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] See Figures 1-9 This utility model discloses an optical accessory connection assembly, including a base 10, a support platform 20, and a locking mechanism 30. The base 10 is provided with a first rotating connection part 11 and a second rotating connection part 21. The support platform 20 can be rotatably connected to the first rotating connection part 11 of the base 10 through the second rotating connection part 21. A clamping member 22 is provided on the support platform 20 for connecting optical accessories. The support platform 20 can rotate through the second rotating connection part 21 and the first rotating connection part 11 of the base 10 to realize the rotation of the optical accessory, so that the use angle of the optical accessory is adjustable.

[0043] Specifically, a first anti-rotation structure 211 is provided on the second rotating connection portion 21 of the support platform 20. The locking mechanism 30 includes a locking member 31 and a guide member 32. The locking member 31 has a first end and a second end that are opposite to each other. The first end is provided with the second anti-rotation structure 311. The first end of the locking member 31 is installed on the second rotating connection portion 21. The second anti-rotation structure 311 at the first end can be correspondingly arranged with the first anti-rotation structure 211 on the second rotating connection portion 21. After the first end moves close to the second rotating connection portion 21, the second anti-rotation structure 311 cooperates with the first anti-rotation structure 211 to prevent rotation. Conversely, after the first end moves away from the second rotating connection portion 21, the second anti-rotation structure 311 disengages from the first anti-rotation structure 211.

[0044] In addition, a guide portion is provided at the second end, and the guide 32 is rotatably mounted at the second end. During the rotation of the guide 32, the guide portion slides to drive the first end to move closer to or away from the second rotating connection portion 21.

[0045] Based on the above structure, when using the optical accessory connection assembly of this utility model, the optical accessory can be connected to the support platform 20 via the clamping member 22 on the support platform 20 during clamping. In some embodiments, the clamping member 22 can be a claw structure, a hook structure, or a threaded connection structure, etc., as long as it can achieve a detachable connection between the optical accessory and the support platform 20. The optical accessory can be a lamp or a camera device, etc.

[0046] When the optical accessory needs to be adjusted in terms of its operating angle, the second rotating connection 21 of the support platform 20 is rotatably connected to the first rotating connection 11 of the base 10. In the adjustment state, the guide 32 rotates around a first direction. At this time, the guide 32 and the guide portion slide until the first end of the guide locking member 31 is away from the second rotating connection 21. In this way, the second anti-rotation structure 311 of the locking member 31 can disengage from the first anti-rotation structure 211 of the second rotating connection 21, so that the second rotating connection 21 can rotate relative to the first rotating connection 11. Thus, the optical accessory on the support platform 20 can rotate relative to the base 10, thereby realizing the adjustment of the operating angle of the optical accessory.

[0047] After the optical accessory is adjusted to the correct angle, to prevent the support platform 20 from rotating relative to the base 10 under non-human force, which would cause instability in the use of the optical accessory, the user can rotate the guide 32 to rotate in a second direction, which is opposite to the first direction. At this time, the guide 32 slides into the guide portion of the second end of the locking member 31, thereby guiding the first end of the locking member 31 to approach the second rotating connection portion 21. The second anti-rotation structure 311 on the first end can then cooperate with the first anti-rotation structure 211 of the second rotating connection portion 21 to prevent the second rotating connection portion 21 from rotating. That is, the rotation of the support platform 20 is restricted, and the optical accessory installed on the support platform 20 can be used stably in this state.

[0048] Compared to related technologies where bolts are used for rotational connection, locking or unlocking is achieved directly by screwing the bolt in or out. However, after a period of use, the bolt threads wear and are prone to loosening. In the embodiment of this application, a second anti-rotation structure 311 is provided on the locking member 31 to cooperate with the first anti-rotation structure 211 of the second rotational connection part 21. At the same time, the first end of the locking member 31 is pressed against the second rotational connection part 21 under the guidance of the guide member 32. Therefore, the locking force is not only applied by the guide member 32 to the locking member 31, but also further prevented from rotating through the cooperation of the second anti-rotation structure 311 and the first anti-rotation structure 211, thereby making the support platform 20 structurally stable in this locked state.

[0049] It should be noted that in this embodiment, the first direction is clockwise and the second direction is counterclockwise. In other embodiments, the guide 32 can also rotate in one direction. That is, the guide 32 can rotate continuously and slide with the guide part, which can also make the first end of the guide locking member 31 approach or move away from the second rotating connection part 21.

[0050] As an optional implementation method, see [link to implementation details]. Figure 3 , Figure 5 as well as Figures 6-9 The locking mechanism 30 also includes an elastic member 33 connected to the second rotating connection 21 to provide an elastic stress, under which the first end of the locking member 31 is driven away from the second rotating connection 21.

[0051] The aforementioned guide portion includes a guide groove 312, and a guide surface 313 is provided in the guide groove 312. The guide surface 313 includes a spiral surface or an inclined surface, and a guide post 321 is provided on the guide member 32 accordingly. The guide post 321 extends into the guide groove 312 and slides in cooperation with the guide surface 313.

[0052] Since the guide surface 313 is a spiral surface or an inclined surface, one end of the spiral surface or inclined surface is close to the bottom wall of the guide groove 312, while the other end of the spiral surface or inclined surface can gradually move away from the bottom wall of the guide groove 312. In this way, when the guide post 321 slides along the guide surface 313, the guide post 321 can be guided to gradually move away from the bottom wall of the guide groove 312.

[0053] During assembly, when the guide member 32 is rotated, the bottom wall of the guide groove 312 faces the first end, while the guide surface 313 of the guide groove 312 gradually moves away from the bottom wall of the guide groove 312 in the rotation direction. After the guide post 321 of the guide member 32 extends into the guide groove 312, when the locking member 31 is in the unlocked state, the guide post 321 of the guide member 32 can be located at the lowest position of the guide groove 312. The elastic stress provided by the elastic member 33 drives the first end to remain away from the second rotating connection part 21.

[0054] When locking is required, the guide 32 rotates, and the guide post 321 can slide along the guide surface 313. The guide 32 remains in the same position in its own axis, and the guide post 321 can press against the second end of the locking member 31, driving the first end of the locking member 31 to approach the second rotating connection part 21, so that the second anti-rotation structure 311 at the first end cooperates with the first anti-rotation structure 211. At this time, the elastic member 33 is compressed.

[0055] In some embodiments, the guide surface 313 is a spiral surface, and the guide post 321 can slide along the spiral surface when the guide member 32 rotates, thereby achieving axial movement guidance.

[0056] Of course, if the guide surface 313 is chosen as an inclined surface, multiple continuous toothed groove structures can be provided in the guide groove 312. The depths of adjacent toothed grooves can be different. In this way, when the guide member 32 rotates, the guide post 321 can slide along the inclined surface of the toothed groove in the circumferential direction, sliding from one toothed groove to another. The elastic stress provided by the elastic member 33 ensures that the guide post 321 can always maintain abutment with the corresponding toothed groove. Since the depths of adjacent toothed grooves are different, the position of the locking member 31 on the shaft is different after the guide post 321 slides to different toothed grooves. Therefore, the first end of the locking member 31 can be guided to move closer to or away from the second rotating connection part 21. In this embodiment, the guide member 32 can rotate continuously in the same direction to drive the locking member 31 closer to or away from the second rotating connection part 21.

[0057] As an optional implementation, the guide portion also includes a guide block 314, that is, the guide portion is formed by the guide block 314 and the guide groove 312, and the guide block 314 and the guide groove 312 are distributed sequentially in the rotation direction of the guide member 32. One end of the guide surface 313 is connected to the guide groove 312, and the other end of the guide surface 313 is connected to the guide block 314. The guide block 314 can form a protruding structure at the end of the guide surface 313. In this way, after the guide post 321 slides along the guide surface 313 to the position of the guide block 314, it can press against the guide block 314 and drive the first end of the locking member 31 to approach. Since the guide block 314 protrudes from the guide groove 312, the guide groove 312 is formed with a recess lower than the guide block 314, which facilitates the processing of the guide structure of the locking member 31.

[0058] More specifically, the second end may be provided with two guide blocks 314, which are spaced apart in the rotation direction of the guide member 32. The recess between the two guide blocks 314 forms a guide groove 312, and the guide surface 313 of the guide groove 312 extends to one of the guide blocks 314. The other guide block 314 forms a limiting end wall at the other end of the guide groove. Two guide posts 321 are provided. When the guide post 321 slides within the guide groove 312, it can be guided by pressure when sliding to one of the guide blocks 314, and when sliding to the other guide block 314, it abuts against it, thus limiting the rotation range of the guide post 321.

[0059] As an optional implementation, both ends of the guide surface 313 may be provided with positioning portions 315. In related embodiments, the positioning portions 315 may be used as positioning grooves. After the guide post 321 slides along the guide surface 313 to the corresponding positioning groove, it can slide into the positioning groove to achieve positioning and prevent the guide post 321 from continuing to slide.

[0060] Of course, the positioning groove can be an arc groove or a beveled groove, or the guide surface 313 can be directly connected to the opening of the positioning groove, which facilitates the sliding in and out of the guide post 321. In other embodiments, the positioning part 315 can also be a positioning notch, or a positioning magnet, with a corresponding magnet structure provided on the sliding post, or positioning can be achieved by magnetic attraction.

[0061] As an optional implementation, the first rotating connection part 11 includes two first rotating arms 111, which are connected to the base 10 at intervals. Correspondingly, the second rotating connection part 21 includes two second rotating arms 212, which are connected to the support platform 20 at intervals. When the support platform 20 and the base 10 are rotated and assembled, the two second rotating arms 212 correspond one-to-one with the two first rotating arms 111, and the corresponding second rotating arms 212 and the first rotating arms 111 are rotatably connected by the connector 41. The locking member 31 of the locking mechanism 30 is connected to one of the second rotating arms 21, and the other second rotating arm 21 is provided with a damping member 40, which is connected to the connector 41.

[0062] Based on this structure, when the support platform 20 rotates, the locking member 31 of the locking mechanism 30 can drive the first end of the locking member 31 away from the second rotating arm 212 when the guide member 32 rotates, so that the second anti-rotation structure 311 at the first end of the locking member 31 is away from the first anti-rotation structure 211 of the second rotating arm 212, and the second rotating arm 212 and the first rotating arm 111 can be released and rotated.

[0063] After the support platform 20 is rotated into position, the locking member 31 of the locking mechanism 30 can drive the first end of the locking member 31 to approach the second rotating arm 212 when the guide member 32 rotates. This causes the second anti-rotation structure 311 at the first end of the locking member 31 to approach the first anti-rotation structure 211 of the second rotating arm 212 and engage in anti-rotation cooperation. The second rotating arm 212 and the first rotating arm 111, which are equipped with the locking mechanism 30, can be locked and not rotate. The second rotating arm 212 and the first rotating arm 111 on the other side are equipped with damping members 40, and there is a certain damping force between them. They are not easy to rotate under non-human external force. This makes the use state of the support platform 20 more stable.

[0064] Of course, locking mechanisms 30 could also be provided on both the first rotating arm 111 and the second rotating arm 212 on both sides to achieve locking or unlocking, but this structure is more complex and more expensive. Therefore, in this embodiment, a locking mechanism 30 is provided on one side and a damping element 40 is provided on the other side to simplify the structure and ensure stable operation.

[0065] As an optional implementation, the first rotating arm 111 is provided with a first rotating seat 112; the second rotating arm 212 is provided with a second rotating seat 213; the second rotating seat 213 is provided with a rotating hole; the first rotating seat 112 is rotatably connected to the rotating hole; a damping pad 214 is provided between the first rotating seat 112 and the rotating hole, so that when the first rotating arm 111 and the second rotating arm 212 rotate relative to each other, the first rotating seat 112 extends into the rotating hole of the second rotating seat 213 for rotational guidance, thus stabilizing the rotating assembly structure. The damping pad 214 is located between the first rotating seat 112 and the inner wall of the rotating hole, increasing rotational damping, which helps control the rotational speed, making the rotation smoother and avoiding impact or instability caused by excessive speed.

[0066] In the relevant embodiments, the damping member 40 includes a connector 41, a damping sleeve 42, and a damping ring 43. The inner side of the damping sleeve 42 is provided with a first conical surface; the outer side of the damping ring 43 is provided with a second conical surface, and the inner side of the damping ring 43 is provided with a third conical surface. The damping sleeve 42 is fitted onto the outside of the damping ring 43, and the damping ring 43 is fitted onto the outside of the second rotating seat 213. The connector 41 passes through the damping sleeve 42 and extends into the rotating hole to be screwed into the first rotating seat 112. During the screwing process, the first conical surface and the second conical surface are tightly fitted together, and the third conical surface presses against the second rotating seat 213.

[0067] The connector 41 is connected to the first rotating base 112 by screwing. During the screwing process, the first conical surface and the second conical surface achieve a tight fit. The conical surface fit can generate a large contact pressure. As the screw is tightened, the two conical surfaces are pressed against each other, forming a tight fit. This tight fit not only increases the friction of the connection part, but also effectively prevents the connector 41 from displacing in the axial and radial directions. In this way, when the support platform 20 is rotated to the corresponding use angle, it is not easy to shift under the action of non-external force, and the use state is stable.

[0068] At the same time, the third conical surface presses against the second rotating seat 213. The pressing action of the third conical surface makes the second rotating seat 213 tightly connected with the relevant components, forming a stable overall structure. The combination of multiple conical surfaces and screw connection means that the connecting part 41 and the rotating seat are constrained and fixed from multiple directions, so that the entire rotating device can still maintain a stable and reliable working state when subjected to large load external force.

[0069] In some implementations, the aforementioned connector 41 can be a bolt structure as in the prior art. During rotational connection, the threaded section of the bolt can pass through the rotation hole and be threaded into the first rotating seat 112, while the bolt head can be externally limited and press the damping sleeve 42 during the bolt screwing in, thereby forming a tighter fit structure. Of course, the connector 41 can also be a screw rod, with one end screwed to the first rotating seat 112 and the other end extending out of the rotation hole and screwed with a nut structure, so that the damping sleeve 42 is pressed by the nut during the screw screwing in.

[0070] As an optional implementation, the first anti-rotation structure 211 includes a plurality of first anti-rotation teeth 2111 arranged circumferentially on the second rotating connection portion; the second anti-rotation structure 311 includes a plurality of second anti-rotation teeth 3111 arranged circumferentially on the first end; the plurality of second anti-rotation teeth 3111 engage with the plurality of first anti-rotation teeth 2111 to prevent rotation, that is, when the locking member 31 is locked, the plurality of second anti-rotation teeth 3111 on the first end of the locking member 31 and the plurality of first anti-rotation teeth 2111 on the second rotating connection portion engage, and there are anti-rotation teeth in the rotational circumferential direction of the second rotating connection portion to prevent rotation, making the anti-rotation structure more stable.

[0071] Of course, the first anti-rotation structure 211 can also be a positioning pin, and the corresponding second anti-rotation structure 311 can be a positioning hole, with the positioning pin inserted into the positioning hole to achieve anti-rotation. In other embodiments, the first anti-rotation structure 211 can also be an anti-rotation block, and the corresponding second anti-rotation structure 311 can also be an anti-rotation block. After the first end of the locking member 31 approaches the second rotating connection part 21, the anti-rotation block of the second anti-rotation structure 311 abuts against the anti-rotation block of the first anti-rotation structure 211, which can also achieve anti-rotation. The specific anti-rotation structure can be selected and set according to actual needs.

[0072] In some implementations, see Figure 3 Furthermore, a limiting block 316 can be provided on the locking member 31, and a limiting groove 113 can be provided on the first rotating connection part 11. Since the second rotating connection part 21 of the supporting platform 20 rotates relative to the first rotating connection part 11 when the supporting platform 20 rotates, the second rotating connection part 21 is a movable structure, while the first rotating connection part 11 is a fixed connection. The locking member 31 is for locking the movable second rotating connection part 21. Therefore, in order to prevent the locking member 31 from rotating relative to the second rotating connection part, a limiting groove 113 can be further provided on the fixed first rotating connection part 11. After the second anti-rotation structure 311 at the first end of the locking member 31 and the first anti-rotation structure 211 of the second rotating connection part 21 are anti-rotated, the limiting block 316 is further extended into the limiting groove 113, thereby preventing the locking member 31 from rotating and making the locking structure more stable.

[0073] It should also be noted that in some embodiments, the above-mentioned guide 32 can be a knob structure, a rotating handle, or a rotating sleeve to facilitate the rotation operation of the guide.
