[0002] Shoes, bras, chairs, bags, clothing, and other items often have drawstrings at their openings. To facilitate tightening or loosening the drawstrings, a drawstring reel is usually installed on the mounting surface of these items. A drawstring reel typically consists of a knob connected to a drive mechanism and a drum. One end of the rope is fixed to the drum. In use, rotating the knob drives the drum to rotate, applying tension to the rope and thus tightening it.

[0003] In related technologies, the drum of the rope reel is generally made of rigid material. The drum is only suitable for mounting surfaces with specific shapes and angles. The relative positions and angles between different parts of the drum cannot be dynamically adjusted according to the real-time shape of the mounting surface. When the mounting surface changes shape under the action of external force, the drum and the mounting surface cannot fit well together. The drum is prone to pressing on the mounting surface, which affects the user experience. Summary of the Invention

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0039] This embodiment provides an adjustment mechanism 101. Please refer to [reference needed]. Figures 1 to 5 The adjusting mechanism 101 includes a rope winding member 1 and a driving member 2. The rope winding member 1 is used to rotate and wind the rope 102, and the driving member 2 is used to drive the rope winding member 1 to rotate. The rope winding member 1 includes multiple winding portions 11. Different winding portions 11 are used to wind different ropes 102 or different parts of the same rope 102, and the relative angle between at least two adjacent winding portions 11 can be changed.

[0040] In this embodiment, when tightening the rope 102, the drive member 2 drives the rope winding member 1 to rotate, thereby causing the rope winding member 1 to wind the rope 102 and achieve the effect of tightening the rope 102. In this application, the rope winding member 1 includes multiple winding portions 11. Different winding portions 11 are used to wind different ropes 102 or different parts of the same rope 102. The relative angle between at least two adjacent winding portions 11 can be changed. When the mounting surface for installing the adjustment mechanism 101 changes shape under the action of external force, the relative angle between at least two adjacent winding portions 11 can be changed to dynamically adjust the relative position and angle between adjacent winding portions 11, so that the rope winding member 1 can adapt to mounting surfaces of different shapes, improve the fit between the rope winding member 1 and the mounting surface, reduce the pressure caused by the rope winding member 1 on the mounting surface, and improve the user experience.

[0041] In this embodiment, the type of driving component 2 is not limited. The driving component 2 can be a motor (not shown in the figure). The motor has an output shaft, one end of which is connected to the rope winding component 1 for transmission. When the output shaft of the motor rotates, it can drive the rope winding component 1 to rotate synchronously around the central axis of the output shaft, so that the rope winding component 1 winds or unwinds the rope 102, thereby achieving the effect of tightening or loosening the rope 102. For example, refer to Figure 6 The driving component 2 can be a knob assembly 21, which includes a knob cover 211 and a first gear 212 connected by a transmission connection. The rope winding component 1 is provided with a winding part 11 and a second gear 14 connected by a transmission connection. The first gear 212 and the second gear 14 are meshed together. When the knob cover 211 is rotated, the knob cover 211 can drive the first gear 212 to rotate. When the first gear 212 rotates, it drives the second gear 14 and the winding part 11 to rotate, thereby causing the rope winding component 1 to wind or unwind the rope 102, achieving the effect of tightening or loosening the rope 102; for example, refer to Figure 7 The driving component 2 can be a pressure rod assembly 22, which includes a pull rod 221 and a drive shaft 222. The pull rod 221 is provided with a first transmission gear 2211. The two ends of the drive shaft 222 are fixed with second transmission gears 2221 that mesh with the first transmission gear 2211. The middle part of the drive shaft 222 is also fixed with a third transmission gear 2222. The rope winding component 1 is provided with a winding part 11 and a fourth transmission gear 15 that are connected by transmission. When the pressure rod is pressed down or pulled up, the first transmission gear 2211 on the pull rod 221 can drive the second transmission gear 2221 to rotate. When the second transmission gear 2221 rotates, it can drive the drive shaft 222 and the third transmission gear 2222 to rotate. When the third transmission gear 2222 rotates, it drives the fourth transmission gear 15 and the winding part 11 on the rope winding component 1 to rotate, thereby causing the rope winding component 1 to wind or unwind the rope 102, achieving the effect of tightening or loosening the rope 102.

[0042] In this embodiment, the number of winding portions 11 is not limited; there can be two, three, or more winding portions 11. The shape of the winding portions 11 is also not limited; they can be cylindrical, spherical, conical, frustum-shaped, or other shapes. The material type of the winding portions 11 is not limited; they can be made of flexible or rigid materials. The size of the winding portions 11 is not limited; different winding portions 11 can have the same or different sizes, and can be set according to actual needs.

[0043] In one embodiment, at least part or all of the rope winding component 1 is made of flexible material or flexible structure. Using flexible material or flexible structure makes the rope winding component 1 easier to bend, allowing it to adapt to mounting surfaces of different shapes and improving the fit between the rope winding component 1 and the mounting surface. Simultaneously, the relatively softness of the flexible material or flexible structure reduces the pressure exerted by the rope winding component 1 on the mounting surface, improving the comfort of using the adjustment mechanism 101. In this embodiment, some of the rope winding components 1 are made of flexible material or flexible structure; alternatively, the entire rope winding component 1 may be made of flexible material, without limitation.

[0044] In one embodiment, please refer to Figure 8 The rope winding component 1 also includes a flexible connector 12, through which two adjacent winding portions 11 are connected. In this embodiment, the flexible connector 12 has a certain degree of flexibility and elasticity. When the mounting surface for installing the adjustment mechanism 101 changes shape under external force, the flexible connector 12 can absorb and disperse the pressure generated by the rope winding component 1 on the mounting surface, reducing the pressure of the rope winding component 1 on the mounting surface. In addition, the flexible connector 12 can bend or stretch with the change of the shape of the mounting surface to dynamically adjust the relative position and angle between adjacent winding portions 11, so that the rope winding component 1 can adapt to mounting surfaces of different shapes, improving the fit and flexibility between the rope winding component 1 and the mounting surface. Furthermore, since two adjacent winding portions 11 are connected through the flexible connector 12, under the drive of the drive component 2, multiple winding portions 11 can rotate synchronously to simultaneously tighten multiple ropes 102 or multiple parts of the same rope 102, improving the effect of the rope winding component 1 in tightening the rope 102.

[0045] In this embodiment, the type of flexible connector 12 is not limited; it can be a spring, rubber stud, rubber expansion joint, flexible sleeve, etc. The fixing method between the winding portion 11 and the flexible connector 12 is also not limited; they can be integrally formed or detachably connected.

[0046] In one embodiment, the arrangement of the driving member 2 and the winding portion 11 is not limited and can be flexibly set according to actual needs. For example, please refer to... Figure 1 and Figure 3 Multiple winding portions 11 can be arranged sequentially and located on the same side of the drive member 2. For example, please refer to... Figure 2 and Figure 4 The driving member 2 is disposed between two or more winding portions 11. In one embodiment, the diameter of the winding portion 11 is not limited, and the diameter of the winding portion 11 can be flexibly set according to actual needs.

[0047] In one embodiment, at least two winding portions 11 have different diameters. Generally, with the same number of rotations, a larger diameter of the winding portion 11 allows for a greater degree of winding of the rope 102. Having at least two winding portions 11 with different diameters can satisfy the tightening requirements of the rope 102 at different locations. For example, when the adjustment mechanism 101 is applied to a shoe, the diameter of the winding portion 11 near the toe can be smaller than the diameter of the winding portion 11 away from the toe, preventing the rope 102 near the toe from becoming overly tight and affecting the comfort of the shoe.

[0048] In one embodiment, the rope winding member 1 has a plurality of winding portions 11, each with the same diameter. In this embodiment, since each winding portion 11 has the same diameter, tightening the rope winding member 1 can make the tightness of the rope 102 in different parts the same or substantially the same, resulting in a better effect of uniformly tightening the rope 102.

[0049] In one embodiment, the adjusting mechanism 101 further includes a transmission component (not shown in the figure), which is tractively connected between the rope winding component 1 and the driving component 2. The transmission component can adjust the included angle between the rope winding component 1 and the driving component 2, so that the included angle between the rope winding component 1 and the driving component 2 can be arbitrarily adjusted. In this embodiment, on the one hand, the driving component 2 can drive the rope winding component 1 to rotate synchronously through the transmission component, thereby causing the rope winding component 1 to wind the rope 102 and achieve the effect of tightening the rope 102; on the other hand, the transmission component can adjust the included angle between the rope winding component 1 and the driving component 2 to dynamically adjust the relative position between the rope winding component 1 and the driving component 2, so that the adjusting mechanism 101 can adapt to mounting surfaces of different shapes, improving the fit and flexibility between the adjusting mechanism 101 and the mounting surface. In this embodiment, the type of transmission component is not limited, and the transmission component can be a universal joint, a spherical joint, a ball joint, etc. In this embodiment, the included angle between the rope winding component 1 and the driving component 2 is not limited. The included angle between the rope winding component 1 and the driving component 2 can be any one or any two of the following: 0°, 1°, 5°, 10°, 30°, 60°, 90°, 120°, 150°, 180°.

[0050] In another embodiment, the adjusting mechanism 101 further includes a transmission member (not shown in the figure), which is driveably connected between the rope winding member 1 and the driving member 2. The driving member 2 can drive the rope winding member 1 to rotate synchronously through the transmission member, and the included angle between the rope winding member 1 and the driving member 2 is not adjustable. For example, the transmission member is made of a rigid material and cannot be bent. The transmission member is rigidly connected to both the rope winding member 1 and the driving member 2, making the included angle between the rope winding member 1 and the driving member 2 non-adjustable.

[0051] In one embodiment, please refer to Figure 8The rope winding member 1 is provided with a rope fixing part 13, which is used to fix the rope 102. In this embodiment, the number of rope fixing parts 13 is not limited, and there can be one, two or more rope fixing parts 13. The position of the rope fixing parts 13 is not limited, and the rope fixing parts 13 can be provided on the winding part 11 of the rope winding member 1, or on the flexible connector 12 of the rope winding member 1. The number of rope fixing parts 13 on each winding part 11 is also not limited, and each winding part 11 can be provided with one or more rope fixing parts 13.

[0052] In one embodiment, there are multiple rope fixing parts 13, which are arranged at intervals along the axial direction of the rope winding member 1. In this embodiment, on the one hand, the multiple rope fixing parts 13 arranged at intervals along the axial direction of the rope winding member 1 can better distribute and fix the rope 102, ensuring that the rope 102 can be evenly arranged on the rope winding member 1 during the winding process, thereby improving the winding efficiency; on the other hand, the rope fixing parts 13 arranged at intervals along the axial direction of the rope winding member 1 can provide multiple support points for the rope 102, thereby enhancing the stability of the rope 102.

[0053] In one embodiment, the rope fixing part 13 is provided with a fixing hole, and the rope 102 can be fixed to the rope fixing part 13 through the fixing hole.

[0054] In one embodiment, the rope fixing part 13 is provided with a fixing buckle, and the rope 102 can be fixed to the rope fixing part 13 by the fixing buckle.

[0055] This application also provides a tightening device 100, please refer to... Figures 1 to 5 It includes a cord 102 and an adjustment mechanism 101 as described above. The adjustment mechanism 101 is connected to the cord 102 and tightens or loosens the cord 102. The type of tightening device 100 is not limited, and the device can be a medical bandage, shoe, clothing, hat, bag or other daily necessities.

[0056] In one specific embodiment, please refer to Figures 1 to 4 The tightening device is a shoe, and the adjusting mechanism 101 is fixed to the shoe tongue to tighten the shoe's strap 102. The diameter of the winding portion 11 near the toe is smaller than the diameter of the winding portion 11 away from the toe, preventing the strap 102 near the toe from being overtightened and affecting the shoe's comfort. In another specific embodiment, please refer to... Figure 5 The tightening device is a garment, and the adjusting mechanism 101 is fixed to the garment to tighten the drawstrings 102 on the garment. The adjusting mechanism 101 has winding parts 11 with different diameters, which can adjust the tightening degree on different parts of the garment as needed.

[0057] In one embodiment, please refer to Figures 1 to 5 The tightening device 100 also includes a body 103, a plurality of ropes 102 connected to the body 103, and a plurality of winding portions 11 arranged sequentially. Each winding portion 11 is connected to at least one rope 102. The winding portion 11 can rotate and wind or unwind the rope 102 to tighten or loosen the body 103. Specifically, the body 103 is provided with a plurality of rope-passing portions 1031 through which the ropes 102 pass. The ropes 102 are passed through the corresponding rope-passing portions 1031 and fixed to the winding portion 11. When the winding portion 11 rotates, it can wind the rope 102 fixed to the winding portion 11 to tighten or loosen the body 103.

[0058] Specifically, traditional tightening devices generally include a rope that passes through different threading parts in sequence, and the end of the rope is fixed to a winding member 1. When tightening the rope, the winding member applies tension to the end of the rope to tighten the body. However, due to the elasticity of the rope itself and the frictional contact with components such as the threading parts, the efficiency of tension transmission decreases with increasing distance, resulting in a better tightening effect for the rope near the winding member and a poorer tightening effect for the rope far from the winding member, affecting the user experience. In this embodiment, multiple winding parts 11 are arranged sequentially, and the multiple windings correspond to multiple ropes 102. When the winding member 1 rotates, it can simultaneously tighten or loosen the ropes 102 at different parts of the body 103. The force applied by the winding member 1 to the ropes 102 is more uniform, and the tightening effect of the ropes 102 is better.

[0059] The embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
