Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rings, in particular to a concentric clamping 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 opener tools on the market that can adapt to bottle caps of different diameters, due to mechanical limitations, they cannot pass through the decorations on the bottle caps, resulting in these tools being only usable for bottle caps of a certain height and shape. For some bottle caps with decorations, such as decorated plastic drinking bottles for children or artistic wine bottles with glass decorations, existing bottle opener tools are difficult to use. In addition, metal screw-on extension rods such as mops and clothes forks can also prevent the extension rods from being smoothly retracted 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 defect 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 by screws. There is a lack of precise debugging methods, and it is difficult to achieve concentric locking with the lens movable ring, so they cannot meet the needs of diversified lenses on the market.

[0006] a synchronous adjustment component, the synchronous adjustment component being rotatably mounted between the decorative groove and the second decorative pressure plate, the synchronous adjustment component being used to adjust a positioning angle between the unilateral fixing claw and the locking catch rod;
[0007] A limit release component is provided inside the first extension slot, and is used to limit or release and reset the synchronous adjustment component.
[0008] Preferably, the synchronous adjustment assembly 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 inside of the first extension groove. 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. A plurality of pushing blocks adapted to the unilateral fixing claws are provided on a 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, several fixing blocks are provided above the mounting groove, and threaded holes are obliquely provided on both sides of the outer surface of the circular base, and two threaded holes are respectively provided through the two fixing blocks, and a metal contact piece is provided on one side of the two pushing blocks 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 engaged 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 engage 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.

[0014] Beneficial effects of the utility model:
[0015] 1. This concentric clamping ring is equipped with a synchronous adjustment component. By rotating the gear and engaging the teeth of the synchronous chainring, the user can easily drive the synchronous chainring to rotate by simply turning a wrench or screwdriver, thereby driving multiple push blocks installed thereon. The push block effectively converts the rotational motion into linear movement of the unilateral fixed claw, 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 adjustment accuracy and stability. The screw rod 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 rod 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 while reducing the difficulty of operation.
[0016] 2. This concentric clamping ring is provided with a limit release assembly. When the synchronous chainring needs to be limited, the limit pawl engages with the teeth through the action of the torsion spring, fixes the position of the synchronous chainring, and makes it only rotate to one side and cannot reset itself, ensuring that the unilateral fixed claw remains stable during the clamping process. When the limit needs to be released, the sliding block slides along the sliding groove, pushing 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 chainring is released. After contacting the limit, the reset spring quickly pulls the synchronous chainring 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, limiting the synchronous chainring. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.
[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.
[0028] Example 1: Figures 1 to 6As shown, the concentric clamping ring includes a ring base 1, and decorative grooves 2 are provided on both sides of the ring base 1. A first decorative pressure plate 3 and a second decorative pressure plate 4 are respectively provided inside the two decorative grooves 2. A mounting groove 5 is provided on the inner side of the decorative groove 2 close to the second decorative pressure plate 4. A first extension groove 9 and a second extension groove 10 are also provided on both sides of the decorative groove 2 close to the second decorative pressure plate 4. A plurality of unilateral fixing claws 6 are rotatably installed on the mounting groove 5, and a locking catch rod 7 is rotatably installed on the other side of the plurality of unilateral fixing claws 6; a synchronous adjustment component is rotatably installed 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 unilateral 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 the synchronous adjustment component. The outer surface of the ring base 1 is circumferentially arranged with a plurality of protrusions;
[0029] During use, the clamping ring is first placed over the object to be clamped, and the synchronous adjustment assembly is rotated to push the single-sided fixed claw 6 to extend synchronously. The locking lever 7, driven by the synchronous adjustment assembly, rotates and adjusts its positioning angle with the fixed claw so that each fixed claw evenly contacts the surface of the object to be clamped, achieving a concentric locking effect. The limit release assembly restricts the position of the synchronous adjustment assembly through the first extension groove 9, ensuring that the fixed claw and locking lever 7 will not accidentally release during the clamping process. After clamping is completed, the limit release assembly maintains its restricted state to prevent the synchronous adjustment assembly from loosening. When release is required, the limit release assembly is operated to release the restriction on the synchronous adjustment assembly, returning it to its initial state, and the single-sided fixed claw 6 is retracted into its original position, completing the reset and release operation of the clamping ring. The mounting groove 5 is designed to accommodate the single-sided fixed claw 6 and is arranged circumferentially to ensure that the fixed claws can apply force synchronously and evenly, achieving a concentric clamping effect. The design of the single-sided fixed claw 6 allows them to contact objects of different diameters and achieve synchronous concentric contraction according to the adjustment of the synchronous adjustment assembly. The connection between the locking catch rod 7 and the fixed claw enhances the clamping force of the device. 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 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 assembly 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 interior 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 a side of the synchronous toothed disc 16 close to the circular base 1. The side of the push block 20 close to the unilateral fixed claw 6 is set in an inclined shape, and the side of the push block 20 away from the unilateral fixed claw 6 is set in a straight shape.
[0031] When clamping is required, the user uses a wrench or 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, and the rotation of the synchronous chainring 16 further drives several pushing blocks 20 installed thereon. Since one side of the pushing block 20 is in the shape of a slope, as the synchronous chainring 16 rotates, the slope 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 the appropriate 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 slot 9, a torsion spring is provided at the connection between the limit pawl 13 and the first extension slot 9, the limit pawl 13 is engaged with a plurality of teeth 18, and a sliding block 14 is also slidably mounted on one side below the first extension slot 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 engage 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 slot 17, and the other end of the return spring 19 is fixedly connected to one end of the second extension slot 10;
[0033] When it is necessary to limit the synchronous chain disk 16, the limiting pawl 13 engages with the teeth 18 through the action of the torsion spring, fixing the position of the synchronous chain disk 16 so that it can only rotate 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. The limiting pawl 13 disengages from the teeth 18 during the process of being lifted, releasing the limiting state of the synchronous chain disk 16. After contacting the limit, the reset spring 19 quickly pulls the synchronous chain disk 16 to reset, without the need for manual adjustment, and then resets the sliding block 14. At the same time, the torsion spring restores the limiting pawl 13 to its initial state, limiting the synchronous chain disk 16.
[0034] Example 2: Figure 2 、 Figure 3 As shown, a plurality of fixing blocks 8 are provided above the mounting groove 5. Threaded holes 11 are obliquely provided on both sides of the outer surface of the annular base 1. Two threaded holes 11 are respectively provided through the two fixing blocks 8. Metal contact sheets are 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 chainring 16, the user can also install the adjusting screw into the threaded hole 11 and start rotating 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 subjected to pressure, and the pushing block 20 moves forward. The movement of the pushing block 20 then drives the synchronous chainring 16 to start rotating synchronously. When the synchronous chainring 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 fixed 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 chainring 16 will not loosen in the reverse direction. The whole process is stable and precise.
