[0049] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0051] Please see Figures 1 to 3This embodiment provides a cord adjuster 100, including: a base 10; a take-up reel 20, on which a first linkage part 210 is provided; an anti-rotation disc 30, which is located above and connected to the base 10, and the take-up reel 20 is located inside the anti-rotation disc 30, with a first anti-rotation part 310 on the side of the anti-rotation disc 30 away from the base 10; and a rotating cover 40, which is located above and rotatably connected to the anti-rotation disc 30, and is pluggable to the take-up reel 20, with a second linkage part 410 and a second anti-rotation part 420 on the side of the rotating cover 40 facing the anti-rotation disc 30, the first linkage part 210 and the second linkage part 410 cooperating, and the first anti-rotation part 310 and the second anti-rotation part 420 cooperating.

[0052] The working principle of the cord adjuster 100 provided in this embodiment is as follows:

[0053] The cord adjuster 100 provided in this embodiment is assembled as follows: First, the take-up reel 20 is placed inside the anti-rotation plate 30. Then, the anti-rotation plate 30 containing the take-up reel 20 is placed on the base 10, and the anti-rotation plate 30 is connected to the base 10. Finally, the rotating cover 40 is placed on the anti-rotation plate 30 and connected to the anti-rotation plate 30 and the take-up reel 20 inside the anti-rotation plate 30. After assembly, the entire cord adjuster 100 is installed on shoes, belts, or small bags via the base 10. It should be understood that after assembly, the first linkage part 210 and the second linkage part 410 are in a cooperating state, the first anti-rotation part 310 and the second anti-rotation part 420 are in a cooperating state, and the rotating cover 40 is inserted into the take-up reel 20. During the tightening of the cord, twisting the rotating cover 40 will produce a continuous "click-click" sound, giving the user a strong sense of participation and interactivity.

[0054] When tightening the cable, simply turn the rotating cover 40 in the direction of tightening (e.g., clockwise). Because the second linkage 410 on the rotating cover 40 engages with the first linkage 210 on the take-up reel 20, turning the cover 40 causes it to rotate, which in turn rotates the take-up reel 20 relative to the anti-rotation disc 30, thus tightening the cable. Simultaneously, the first anti-rotation disc 310 and the second anti-rotation disc 420 work together to limit the cable tension when it reaches the appropriate position. When loosening the cable, successfully pulling or pressing the rotating cover 40 will produce a "click" sound, providing the user with a strong sense of participation and interaction.

[0055] When it is necessary to loosen the cord, first pull the rotating cap 40 upwards, that is, pull the rotating cap 40 out of the take-up reel 20, and then directly pull the cord passing through the garment. The take-up reel 20 will rotate relative to the anti-rotation disc 30, thus loosening the cord. After the cord tension is adjusted to the appropriate position, press the rotating cap 40 downwards, so that the rotating cap 40 is inserted into the take-up reel 20. This causes the first linkage part 210 and the second linkage part 410 to be in a cooperating state, and the first anti-rotation part 310 and the second anti-rotation part 420 to be in a cooperating state, thereby limiting the cord that has been loosened to the appropriate position.

[0056] The beneficial effects of the cord adjuster 100 provided in this embodiment are at least as follows:

[0057] (1) The cord adjuster 100 provided in this embodiment requires very few parts to be assembled, the assembly process is very simple, and the parts are assembled from top to bottom, which reduces the probability of errors in production and use. Since there are very few parts to be assembled, production efficiency is greatly improved, production costs are reduced, the equipment for producing each part is simpler, and the total number of production equipment is also greatly reduced.

[0058] (2) The cord adjuster 100 provided in this embodiment can tighten the cord simply by turning the rotating cover 40 when it is necessary to tighten the cord and limit the tightened cord. The operation process is simple. When it is necessary to loosen the cord, the rotating cover 40 needs to be pulled up and the cord needs to be loosened. After it is loosened to a suitable position, the rotating cover 40 is pressed back to its original position to limit the loosened cord. This can reduce the loosening of the cord caused by misoperation during normal use.

[0059] (3) The cord adjuster provided in this embodiment will make a continuous "clicking" sound when the cord is tightened by twisting the cover, and will make a "snap" sound when the cord is loosened by successfully pulling up or pressing the cover. The process of tightening and loosening the cord gives the user a strong sense of participation and interactivity, which improves the user experience.

[0060] In one embodiment, see Figure 2 and Figure 3 The first linkage part 210 includes a plurality of first linkage teeth 211, which are spaced apart and arranged in a circle; the second linkage part 410 includes a plurality of second linkage teeth 411, which are spaced apart and arranged in a circle; the plurality of first linkage teeth 211 and the plurality of second linkage teeth 411 engage alternately. Through the alternating engagement of the plurality of first linkage teeth 211 and the plurality of second linkage teeth 411, when it is necessary to tighten the rope, simply twisting the rotating cover 40 will cause the take-up reel 20 to rotate, thereby achieving rope tightening. Its linkage structure is simple and stable. In one embodiment, please refer to [further details omitted]. Figure 2 and Figure 3 The first anti-rotation part 310 includes at least one anti-rotation arm 311, one end of which is connected to the anti-rotation disk 30, and the other end of which is a free end. The anti-rotation arm 311 is provided with at least one first anti-rotation tooth 312. The second anti-rotation part 420 includes a plurality of second anti-rotation teeth 421, which are spaced apart and arranged in a circle. The first anti-rotation tooth 312 and the second anti-rotation tooth 421 are engaged alternately.

[0061] When it is necessary to limit the tension of the cord, during the twisting of the rotating cover 40, the second anti-rotation tooth 421 on the rotating cover 40 will engage with the first anti-rotation tooth 312 on the free end of the anti-rotation arm 311 one by one. That is, each state of cord tension can be limited, and a "click" sound is emitted during the rotation to remind the user. When the cord is adjusted to the appropriate position, stop twisting the rotating cover 40 to achieve the limit of cord tension. When it is necessary to limit the loosening of the cord, during the loosening process, the rotating cover 40 is in the upward pulling state, and the first anti-rotation tooth 312 and the second anti-rotation tooth 421 are not engaged. When the cord is tightened to the appropriate state, press the rotating cover 40 down to make the first anti-rotation tooth 312 and the second anti-rotation tooth 421 engage, thus limiting the cord when it is loosened to the appropriate state. The first anti-rotation part 310 and the second anti-rotation part 420 provided above have a simple structure and can stably limit the tension of the rope.

[0062] It should be understood that in this embodiment, the tightening of the rope and the limiting of the tightened rope are achieved by turning the rotating cover 40 clockwise. When the setting direction of the anti-rotation arm 311 is changed, the rotating cover 40 can be turned counterclockwise to tighten the rope and limit the tightened rope.

[0063] Optionally, the first anti-rotation part 310 includes a plurality of anti-rotation arms 311, and the plurality of anti-rotation arms 311 are equally spaced. Each anti-rotation arm 311 is provided with a plurality of first anti-rotation teeth 312, and the plurality of first anti-rotation teeth 312 are spaced apart.

[0064] Optionally, the first anti-rotation part 310 includes four anti-rotation arms 311, and the four anti-rotation arms 311 are equally spaced, and each anti-rotation arm 311 is provided with two or three first anti-rotation teeth 312.

[0065] It should be understood that the number and arrangement of the anti-rotation arm 311 and the first anti-rotation tooth 312 are not limited to the above-mentioned situation, and can also be other situations, which are not limited here.

[0066] In one embodiment, please refer to... Figure 2 and Figure 3 The anti-rotation disc 30 is provided with a through cavity 320, the take-up reel 20 is disposed in the through cavity and is limited by the through cavity, the take-up reel 20 is provided with a plug-in connection hole 220, the rotating cover 40 is provided with a plug-in connection post 430 on the side facing the anti-rotation disc 30, and the plug-in connection post 430 is fixedly connected to the rotating cover 40, and the plug-in connection post 430 is plugged into and connected to the plug-in connection hole 220 through the through cavity 320.

[0067] The rotating cover 40 and the take-up reel 20 are connected by the cooperation of the plug-in connecting post 430 and the plug-in connecting hole 220, which realizes the upper and lower limit of the rotating cover 40. The connection structure is simple, easy to assemble and operate. The through cavity 320 can not only stably limit and fix the take-up reel 20 in the anti-rotation plate 30, but also facilitate the cooperation of the plug-in connecting post 430 and the plug-in connecting hole 220.

[0068] Optionally, the plug-in connecting post 430 is located in the middle of the rotating cover 40, the second linkage part 410 is located around the plug-in connecting post 430, and the second anti-rotation part 420 is located around the second linkage part 410; the plug-in connecting hole 220 is located in the middle of the take-up reel 20, the first linkage part 210 surrounds the plug-in connecting hole 220, and the first anti-rotation part 310 is located at the edge of the anti-rotation disc 30 and is located around the first linkage part 210.

[0069] In one embodiment, please refer to... Figure 2 and Figure 3 The plug-in connecting post 430 includes: a first connecting post 431, the free end of the first connecting post 431 away from the rotating cover 40 having an outwardly convex first limiting protrusion 4311; a second connecting post 432, the free end of the second connecting post 432 away from the rotating cover 40 having an outwardly convex second limiting protrusion 4321; the first connecting post 431 and the second connecting post 432 are spaced apart; the plug-in connecting hole 220 has an inwardly concave limiting recess 221 inside, and both the first limiting protrusion 4311 and the second limiting protrusion 4321 are limited and engaged with the limiting recess 221.

[0070] During the insertion of the plug-in connector 430 into the plug-in connector hole 220, the free ends of the first connector 431 and the second connector 432 are pressed against the gap between the first connector 431 and the second connector 432, thereby inserting the first connector 431 and the second connector 432 into the plug-in connector hole 220. At this time, the outwardly protruding first limiting protrusion 4311 on the first connector 431 and the outwardly protruding second limiting protrusion 4321 on the second connector 432 cooperate with the limiting recess 221 to limit and engage the plug-in connector 430 inserted into the plug-in connector hole 220. A "click" sound is emitted during the insertion of the first connector 431 and the second connector 432 into the plug-in connector hole 220. When the plug-in connector 430 is pulled out of the plug-in connector hole 220, that is, when the rotating cover 40 is pulled upwards, the free ends of the first connector 431 and the second connector 432 are squeezed into the gap between the first connector 431 and the second connector 432, thereby pulling the first connector 431 and the second connector 432 out of the plug-in connector hole 220. The above-mentioned matching structure of the plug-in connector 430 and the plug-in connector hole 220 is ingeniously designed and simple in structure, with a stable plug-in structure and convenient and quick operation. A "snap" sound will also be made during the process of pulling the first connector 431 and the second connector 432 out of the plug-in connector hole 220.

[0071] Optionally, a recess 222 is provided at the top concave edge of the plug-in connection hole 220. When the plug-in connection post 430 is pulled out from the plug-in connection hole 220, the first limiting protrusion 4311 and the second limiting protrusion 4321 are both located in the recess 222.

[0072] Optionally, the cross-sectional shape of the first limiting protrusion 4311, the second limiting protrusion 4321, and the limiting recess 221 is a right triangle. The right-angled side is to guide the force to prevent slippage, and the hypotenuse is to automatically guide the device to the position when pressed.

[0073] It should be understood that the plug-in connection post 430 is not limited to the first connection post 431 and the second connection post 432 mentioned above, but may also include other numbers of connection posts, such as three or more connection posts, which are not limited here.

[0074] In one embodiment, please refer to... Figure 2 and Figure 3The stop disc 30 is provided with a first threading channel 330 and a second threading channel 340, and the take-up reel 20 is provided with a first threading hole 230 and a second threading hole 240. One end of the rope is sequentially threaded through the first threading channel 330 and the first threading hole 230 and fixed at the first threading hole 230. The other end of the rope is sequentially threaded through the second threading channel 340 and the second threading hole 240 and fixed at the second threading hole 240.

[0075] In practical applications, the assembly process of the cord and cord adjuster 100 is as follows: after the cord passes back and forth through an object (e.g., shoes, belt, small bag), one end of the cord passes through the first threading channel 330 and the first threading hole 230 in sequence, and is knotted and fixed at the first threading hole 230. The other end of the cord then passes through the second threading channel 340 and the second threading hole 240, and is knotted and fixed at the second threading hole 240, thus assembling the cord onto the cord adjuster 100.

[0076] In one embodiment, please refer to... Figure 2 and Figure 3 The stop plate 30 is provided with at least one locking piece 350, and the base 10 is provided with at least one locking position 110. The locking piece 350 is engaged with the locking position 110. The base 10 is provided with a first limiting recess 120 and a second limiting recess 130. The first threading channel 330 is located in the first limiting recess 120 and is limited by the first limiting recess 120. The second threading channel 340 is located in the second limiting recess 130 and is limited by the second limiting recess 130.

[0077] The first threading channel 330 is positioned within the first limiting recess 120, and the second threading channel 340 is positioned within the second limiting recess 130. This achieves the limitation of the rotation stop 30 and also facilitates the extension of the rope out of the rope adjuster 100. The cooperation of the clip 350 and the clip 110 ensures that the rotation stop 30 is stably connected to the base 10. The connection structure is simple and robust.

[0078] Optionally, the anti-rotation disc 30 is provided with two locking pieces 350, and the base 10 is provided with two locking slots 110. This arrangement allows the anti-rotation disc 30 to be more stably connected to the base 10. It should be understood that the number of locking pieces 350 and locking slots 110 is not limited to the above-described scenario, and other scenarios are also possible, which are not limited here.

[0079] In one embodiment, see Figure 4The base 10 includes a first connecting plate 140, and the edge of the first connecting plate 140 is provided with a first connecting hole 141. The first connecting hole 141 facilitates the stable fixing of the entire cord adjuster 100 to the wearable.

[0080] Optionally, the first connecting plate 140 is arched to facilitate installation on wearable items (e.g., shoes) and fit snugly against the shoe upper.

[0081] Optionally, the first connecting plate 140 is flat, which facilitates installation on a flat box and fits the box surface.

[0082] In another embodiment, please refer to Figure 3 The base includes a second connecting plate 150, with a second connecting hole 151 on its edge and a notch 152. The second connecting hole 151 facilitates the stable fixing of the entire cord adjuster 100 to the wearable. The notch 152 allows the cord adjuster 100 to be closer to the shoe upper, preventing interference with the foot and reducing discomfort. The notch also facilitates disassembly; it can be easily removed by pushing it in a designated direction with a disassembly rod, making maintenance convenient.

[0083] Optionally, the second connecting plate 150 is arched to facilitate installation on wearable items (e.g., shoes) and fit snugly against the shoe upper.

[0084] Optionally, the second connecting plate 150 is flat, making it easy to install on a flat box and fit against the box surface.

[0085] In one embodiment, please refer to... Figure 2 and Figure 3 The outer side wall of the anti-rotation disc 30 is provided with an annular limiting protrusion 360, and the inner side wall of the rotating cover 40 is provided with at least one limiting protrusion 440. The limiting protrusion 440 and the top of the rotating cover 40 form a limiting groove 441. The rotating cover 40 is located outside the anti-rotation disc 30, and the annular limiting protrusion 360 is placed in the limiting groove 441 and is limited by the cooperation of the annular limiting protrusion 360 and the limiting groove 441. The rotating cover 40 can move up and down relative to the anti-rotation disc 30.

[0086] The cooperation of the limiting groove 441 and the annular limiting protrusion 360 enables the rotating cover 40 to be limited and connected to the anti-rotation plate 30.

[0101] (1) The cord adjuster 100, wearable, and adjustment method provided in this embodiment require very few parts to assemble, and the assembly process is very simple. The parts are assembled from top to bottom, which reduces the probability of errors during production and use. Since there are very few parts to assemble, production efficiency is greatly improved, production costs are reduced, the equipment for producing each part is simpler, and the total number of production equipment is also greatly reduced. (2) When the cord adjuster 100, wearable, and adjustment method provided in this embodiment need to tighten the cord, simply twist the rotating cover 40 to tighten the cord and limit the tightened cord. The operation process is simple. When the cord needs to be loosened, the rotating cover 40 needs to be pulled up, and then the cord needs to be loosened. After it is loosened to a suitable position, the rotating cover 40 is pressed back to its original position to limit the loosened cord. This can reduce the loosening of the cord caused by misoperation during normal use. (3) The cord adjuster 100, wearable device, and adjustment method provided in this embodiment produce a continuous "clicking" sound when the cord is tightened by twisting the rotating cover, and a "snap" sound when the cord is loosened by successfully pulling up or pressing the rotating cover. The process of tightening and loosening the cord gives the user a strong sense of participation and interactivity, improving the user experience.
