Description

Technical Field

[0001] The invention relates to the technical field of circular rings, in particular to a concentric clamping circular ring. Background Art

[0002] In film and television shooting, most manual lenses need to be installed on auxiliary focusing devices. However, the movable ring on the lens cannot be used without a standard gear ring. Similar problems also exist in daily life. For example, the bottle caps of many products are difficult to unscrew due to their design. Although there are some bottle cap opening tools on the market that can adapt to bottle caps of different diameters, they cannot pass through the decorations on the bottle caps due to mechanical structure limitations, resulting in these tools being able to only be used for bottle caps of a certain height and shape. For some bottle caps with decorations, such as plastic drinking bottles with decorations for children or artistic wine bottles with glass decorations, existing bottle cap opening tools are difficult to apply. In addition, metal screw-on extension rods such as mops and clothes forks can also fail to be retracted smoothly if they are used for too long or tightened too hard.

[0003] Currently, the common gear rings on the market are mainly divided into plastic gear rings and metal gear rings. The advantage of plastic gear rings is that they can adapt to lenses of different diameters, but due to the characteristics of the material, plastic gear rings may deform during use, resulting in changes in the tooth spacing, which in turn affects the focusing effect. Metal gear rings are relatively unlikely to deform, but their disadvantage is that they cannot adapt to lenses of different diameters, and as a customized product, they can usually only be customized for lenses of specific diameters. In addition, metal gear rings need to consider tolerances during installation and are fixed with screws. There is a lack of precise debugging methods, and it is difficult to achieve concentric locking with the lens movable ring, and therefore cannot meet the needs of diversified lenses on the market. Summary of the invention

[0004] In view of this, the purpose of the present invention is to propose a concentric clamping ring to solve the problem of being unable to adapt to different diameter ranges while satisfying concentric clamping under the requirement of lightness and thinness.

[0005] Based on the above purpose, the present invention provides a concentric clamping ring, including a ring base, both sides of the ring base are provided with decorative grooves, the insides of the two decorative grooves are respectively provided with a first decorative pressure plate and a second decorative pressure plate, the inner side of the decorative groove close to the second decorative pressure plate is provided with a mounting groove, the two sides of the decorative groove close to the second decorative pressure plate are also provided with a first extension groove and a second extension groove, a plurality of single-sided fixing claws are rotatably installed on the mounting groove, and the other sides of the plurality of single-sided fixing claws are rotatably installed with locking catch rods;

[0006] A synchronous adjustment component, the synchronous adjustment component is rotatably installed between the decorative groove and the second decorative pressure plate, and the synchronous adjustment component is used to adjust the positioning angle of the single-sided fixed claw and the lock catch rod;

[0007] A limit release component, wherein the limit release component is arranged inside the first extension groove, and the limit release component is used to limit or release and reset the synchronous adjustment component.

[0008] Preferably, the synchronous adjustment component includes a synchronous sprocket rotatably installed between the decorative groove and the second decorative pressure plate, and a rotating gear rotatably installed on one side of the first extension groove, and positioning grooves are provided on both sides of the synchronous sprocket, and a plurality of teeth meshing with the rotating gear are provided above one of the positioning grooves, and a plurality of pushing blocks adapted to the single-sided fixed claws are provided on one side of the synchronous sprocket close to the circular base.

[0009] Preferably, a side of the pushing block close to the unilateral fixing claw is configured as an inclined surface, and a side of the pushing block away from the unilateral fixing claw is configured as a straight surface.

[0010] Preferably, a plurality of fixing blocks are arranged above the mounting groove, threaded holes are obliquely provided on both sides of the outer surface of the circular base, two threaded holes respectively penetrate the two fixing blocks, and a metal contact sheet is provided on one side of the two pushing blocks located on one side of the two fixing blocks.

[0011] Preferably, the limit release assembly includes a limit pawl rotatably installed on the other side of the first extension groove, a torsion spring is provided at the connection between the limit pawl and the first extension groove, the limit pawl is meshed with a plurality of the teeth, and a sliding block is also slidably installed on the lower side of the first extension groove, the sliding block is adapted to the limit pawl, the sliding block is used to lift the limit pawl, and the limit pawl does not mesh with the teeth during the lifting process, the sliding block is arranged in a T shape, and a sliding groove adapted to the sliding block is provided on one side of the second decorative pressure plate.

[0012] Preferably, a return spring is fixedly connected to one side of the other positioning slot, and the other end of the return spring is fixedly connected to one end of the second extension slot.

[0013] Preferably, a plurality of protrusions are arranged circumferentially on the outer surface of the annular base.

[0014] Beneficial effects of the present invention:

[0015] 1. This concentric clamping ring is provided with a synchronous adjustment component. By rotating the gear and meshing with the teeth of the synchronous chainring, the user only needs to simply turn a wrench or a screwdriver to easily drive the synchronous chainring to rotate, thereby driving multiple push blocks installed thereon. The push block effectively converts the rotational motion into the linear movement of the unilateral fixed claw, thereby realizing synchronous clamping, avoiding the tedious steps of adjusting the fixed claws one by one in the traditional way, and greatly simplifying the operation process. Secondly, the addition of the adjustment screw further enhances the accuracy and stability of the adjustment. The screw can accurately control the movement of the push block by supporting the metal contact piece on the push block, thereby realizing the rotation adjustment of the synchronous chainring. Since the threaded hole and the screw have self-locking properties, they can remain fixed during the adjustment process and will not loosen in the reverse direction, ensuring accurate and stable operation. In addition, this setting can also adapt to objects of different diameters, and the adjustment process is smooth and reliable, which greatly improves work efficiency and reduces the difficulty of operation.

[0016] 2. This type of concentric clamping locking ring is equipped with a limit release component. When the synchronous sprocket needs to be limited, the limit pawl engages with the teeth through the action of the torsion spring, fixes the position of the synchronous sprocket, and allows it to rotate only to one side and cannot reset itself, ensuring that the single-sided fixed claw remains stable during the clamping process. When the limit needs to be released, the sliding block slides along the sliding groove to push the limit pawl to move upward. The limit pawl disengages from the teeth during the process of being lifted, and the limited state of the synchronous sprocket is released. After contacting the limit, the reset spring quickly pulls the synchronous sprocket to reset, without the need for manual adjustment, and then resets the sliding block. At the same time, the torsion spring restores the limit pawl to its initial state to limit the synchronous sprocket. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1: Figures 1 to 6As shown, the concentric clamping ring comprises a ring base 1, both sides of the ring base 1 are provided with decorative grooves 2, the inside of the two decorative grooves 2 are respectively provided with a first decorative pressure plate 3 and a second decorative pressure plate 4, the inner side of the decorative groove 2 close to the second decorative pressure plate 4 is provided with a mounting groove 5, the two sides of the decorative groove 2 close to the second decorative pressure plate 4 are also provided with a first extension groove 9 and a second extension groove 10, a plurality of single-sided fixing claws 6 are rotatably mounted on the mounting groove 5, and the other sides of the plurality of single-sided fixing claws 6 are rotatably mounted with locking catch rods 7; a synchronous adjustment component, the synchronous adjustment component is rotatably mounted between the decorative groove 2 and the second decorative pressure plate 4, and the synchronous adjustment component is used to adjust the positioning angle of the single-sided fixing claw 6 and the locking catch rod 7; a limit release component, the limit release component is arranged inside the first extension groove 9, and the limit release component is used to limit or release and reset the synchronous adjustment component, wherein the outer surface of the ring base 1 is provided with a plurality of protrusions circumferentially arranged;

[0029] When in use, firstly, the clamping ring is put on the object to be clamped as required, the synchronous adjustment component is rotated, and the unilateral fixed claw 6 is pushed out synchronously. The lock catch rod 7 is rotated under the drive of the synchronous adjustment component, and the fixed claw is adjusted to adjust its positioning angle so that each fixed claw evenly contacts the surface of the object to be clamped, so as to achieve the effect of concentric locking. The limit release component limits the position of the synchronous adjustment component through the first extension groove 9 to ensure that the fixed claw and the lock catch rod 7 will not be accidentally loosened during the clamping process. After the clamping is completed, the limit release component maintains its limit state to prevent the synchronous adjustment component from loosening. When it is necessary to loosen, the limit release component is operated to release the restriction on the synchronous adjustment component, so that the synchronous adjustment component returns to the initial state, and the unilateral fixed claw 6 is retracted to the original position, completing the reset and release operation of the clamping ring, wherein the installation groove 5 is set to accommodate the unilateral fixed claw 6, and through the circumferential arrangement, it is ensured that the fixed claw can apply force synchronously and evenly to achieve the effect of concentric clamping. The design of the unilateral fixed claw 6 can make them contact with objects of different diameters, and realize synchronous concentric contraction according to the adjustment of the synchronous adjustment component. The clamping force of the device is enhanced by connecting the locking catch rod 7 with the fixed claw. The synchronous adjustment component is used to adjust the positioning angle of the single-sided fixed claw 6 and the locking catch rod 7, and adjust the position of all the fixed claws at the same time to ensure that each fixed claw contracts synchronously during clamping, making the entire clamping process more efficient and balanced, and avoiding the problem of unstable clamping due to the asynchronous displacement of individual claws.

[0030] like Figures 2 to 6As shown, the synchronous adjustment component includes a synchronous toothed disc 16 rotatably mounted between the decorative groove 2 and the second decorative pressure plate 4, and a rotating gear 12 rotatably mounted on one side of the inner side of the first extension groove 9. Positioning grooves 17 are provided on both sides of the synchronous toothed disc 16. A plurality of teeth 18 meshing with the rotating gear 12 are provided above one of the positioning grooves 17. A plurality of push blocks 20 adapted to the unilateral fixed claw 6 are provided on one side of the synchronous toothed disc 16 close to the annular base 1. The side of the push block 20 close to the unilateral fixed claw 6 is set to be in an inclined shape, and the side of the push block 20 away from the unilateral fixed claw 6 is set to be in a straight shape.

[0031] When clamping is required, the user uses a wrench or a screwdriver to tighten the rotating gear 12 installed in the first extension groove 9, and the rotating gear 12 engages with the teeth 18 on the synchronous chainring 16. The rotational movement of the teeth 18 drives the synchronous chainring 16 to rotate together. The rotation of the synchronous chainring 16 further drives a number of pushing blocks 20 installed thereon. Since one side of the pushing block 20 is in the shape of an inclined surface, as the synchronous chainring 16 rotates, the inclined surface gradually pushes the unilateral fixed claw 6, so that the fixed claw moves forward synchronously to clamp the object to be clamped. As the synchronous chainring 16 continues to rotate, the angle of the unilateral fixed claw 6 is also adjusted until a suitable clamping degree is reached. Through a simple twisting operation, the positions of multiple fixed claws can be adjusted at the same time, avoiding the complicated steps of adjusting the fixed claws one by one, greatly simplifying the operation process and improving work efficiency.

[0032] like Figure 3 , Figure 5 , Figure 6 As shown, the limit release assembly includes a limit pawl 13 rotatably mounted on the other side of the first extension groove 9, a torsion spring is provided at the connection between the limit pawl 13 and the first extension groove 9, the limit pawl 13 is meshed with a plurality of teeth 18, and a sliding block 14 is also slidably mounted on one side below the first extension groove 9, the sliding block 14 is adapted to the limit pawl 13, the sliding block 14 is used to lift the limit pawl 13, and the limit pawl 13 does not mesh with the teeth 18 during the lifting process, the sliding block 14 is arranged in a T shape, a sliding groove 15 adapted to the sliding block 14 is provided on one side of the second decorative pressure plate 4, a return spring 19 is fixedly connected to one side of the other positioning groove 17, and the other end of the return spring 19 is fixedly connected to one end of the second extension groove 10;

[0033] When it is necessary to limit the synchronous sprocket 16, the limiting pawl 13 engages with the teeth 18 through the action of the torsion spring, fixes the position of the synchronous sprocket 16, and allows it to rotate only to one side and cannot reset itself, ensuring that the unilateral fixed claw 6 remains stable during the clamping process; when it is necessary to release the limit, the sliding block 14 slides along the sliding groove 15, pushing the limiting pawl 13 to move upward, and the limiting pawl 13 disengages from the teeth 18 during the process of being lifted, releasing the limiting state of the synchronous sprocket 16, and after contacting the limit, the reset spring 19 quickly pulls the synchronous sprocket 16 to reset, without the need for manual adjustment, and then resets the sliding block 14, and at the same time the torsion spring restores the limiting pawl 13 to its initial state, limiting the synchronous sprocket 16.

[0034] Embodiment 2: Figure 2 , Figure 3 As shown, a plurality of fixing blocks 8 are arranged above the mounting groove 5, and threaded holes 11 are obliquely provided on both sides of the outer surface of the annular base 1, and two threaded holes 11 are respectively provided through the two fixing blocks 8, and a metal contact sheet is provided on one side of the two pushing blocks 20 located on one side of the two fixing blocks 8;

[0035] When the user needs to adjust the synchronous sprocket 16, the user can also install the adjusting screw into the threaded hole 11 and start to rotate the screw. As the screw is gradually screwed into the threaded hole 11, the end of the screw will gradually press against the metal contact piece on the pushing block 20. As the screw continues to rotate, the metal contact piece is under pressure and the pushing block 20 moves forward. The movement of the pushing block 20 then drives the synchronous sprocket 16 to start rotating synchronously. When the synchronous sprocket 16 rotates, it pushes other pushing blocks 20 and adjusts the position of the unilateral fixing claw 6 at the same time to ensure that all the fixing claws move synchronously to clamp or release the target object. Due to the self-locking performance of the threaded hole 11 and the screw, the position of the screw can be stably maintained during the adjustment process to ensure that the synchronous sprocket 16 will not loosen in the reverse direction. The whole process is stable and precise.
