Among them, three inner clamping strips 11 are fixedly connected to the knob 1, three positioning blocks 13 corresponding to the inner clamping strips 11 are fixedly connected to the knob 1, and an outer clamping strip 12 is fixedly connected to the inner side of the knob 1.

[0038] like Figure 3 to Figure 4 As shown, the rotating member 2 has a pawl 21, an axial positioning groove 22 and a first paddle 23. The pawl 21 is located outside the rotating member 2, and the pawl 21 and the rotating member 2 are an integral structure. The pawl 21 is composed of a pawl arm 211, a pawl tooth 212 and a pawl protrusion 213. The pawl arm 211 is elastic, and an external force is applied to the pawl tooth 212 to force it to return to its original position.

[0039] like Figure 7 As shown, the knob 1 is connected to the rotating member 2 by the cooperation of the inner clamping strip 11 and the outer clamping strip 12. The rotating member 2 has an axial positioning groove 22 that matches the positioning block 13. The axial positioning grooves 22 are equidistantly distributed on the top of the rotating member 2 in the axial direction, and a plurality of first paddles 23 are fixedly connected to the bottom of the rotating member 2. During installation, the positioning block 13 on the knob 1 is aligned with the axial positioning groove 22, and then the positioning block 13 is inserted into the axial positioning groove 22, and finally the knob 1 is fixed to the rotating member 2 by the inner clamping strip 11 and the outer clamping strip 12.

[0040] like Figure 8 As shown, the fixing member 3 has a circumferential positioning clip 31, a limit block 32, a traction hole 33, a ratchet 34 and a groove 35. The circumferential positioning clip 31 is fixedly connected to both sides of the lower end of the fixing member 3, and the circumferential positioning clip 31 includes a small clip 311 and a large clip 312. The limit block 32 is fixedly connected to both sides of the lower end of the fixing member 3, and is staggered with the small clip 311 and the large clip 312. The traction hole 33 is located on both sides of the fixing member 3, and the traction hole 33 is connected to the fixing member 3. A groove 35 is also provided in the middle of the fixing member 3, and the groove 35 has a certain slope, and a plurality of first paddles 23 rotate in the groove.

[0041] like Fig.12As shown, the arc-shaped member 5 has a circumferential positioning slot 51, a limiting slot 52, an arc-shaped slot 53 and a bottom plate 54. The circumferential positioning slot 51 is arranged on both sides of the arc-shaped member 5, and the circumferential positioning slot 51 includes a small slot 511 and a large slot 512. The small slot 511 and the large slot 512 cooperate with the small clamping strip 311 and the large clamping strip 312 respectively, and are used to limit the circumferential rotation of the fixing member 3 on the arc-shaped member 5. The limiting slot 52 is arranged on both sides of the inner side of the arc-shaped member 5, and matches with the limiting block 32. When installing the fixing member 3 and the arc-shaped member 5, the limiting block 32 on the fixing member 3 is first inserted into the limiting slot 52, and then the small clamping strip 311 and the large clamping strip 312 are fixed in the small slot 511 and the large slot 512 respectively.

[0042] like Figure 10 to Figure 11 As shown, the winding post 4 has a rope threading hole 41, a rotating disk 42 and a second paddle 43. The rope threading hole 41 is located on both sides of the winding post 4, and the rope threading hole 41 and the traction hole 33 are at the same height. The rotating disk 42 is fixedly connected to the winding post 4, wherein the winding post 4 is rotatably connected to the fixing member 3 via the rotating disk 42. The inner aperture of the rotating disk 42 is also fixed with second paddles 43 corresponding to the number of the first paddles 23, and the first paddles 23 cooperate with the second paddles 43. The first paddle 23 arranged at the bottom of the rotating member 2 is engaged with the second paddle 43 arranged on the top of the winding post 4, and both the first paddle 23 and the second paddle 43 have an arc bending portion 231.

[0043] The middle of the winding post 4 is also provided with an anastomosis post 44, and the top of the anastomosis post 44 is provided with a limiting protrusion 45. The bottom of the anastomosis post 44 is provided with mounting clips 46 on both sides, and the mounting clips 46 cooperate with the mounting grooves 47 on the outer wall of the winding post 4 to fix the anastomosis post 44 to the winding post 4.

[0044] The bottom of the winding column 4 is provided with two accommodating cavities 48, and a small hole 49 for threading a rope is connected to the accommodating cavities 48. The small hole 49 for threading a rope is connected to the hole 41, and its diameter is smaller than that of the hole 41. The rope passes through the hole 41, and the small hole 49 for threading a rope is located in the accommodating cavities 48. A knot is tied at the end of the rope, and the diameter of the knot is larger than that of the hole 49 for threading a rope.

[0045] The specific installation method of the retractable knob buckle of the utility model is as follows: first, assemble the knob 1 and the rotating member 2. During operation, ensure that the positioning block 13 of the knob 1 is accurately aligned with the positioning hole, then push the positioning block 13 into the positioning hole, and finally use the synergy of the inner card strip 11 and the positioning block 13 to fix the knob 1 on the rotating member 2. This step benefits from the exquisite cooperation between the inner card strip 11 and the circumferential positioning groove 24 of the rotating member 2. Next, dock the rotating member 2 with the fixed member 3. The specific steps involve: pre-aligning the axis of the two parts, then adjusting the ratchet 34 on the fixed member 3 to ensure accurate engagement with the ratchet of the rotating member 2, and finally realizing the smooth sliding function of the rotating member 2 on the fixed member 3 by embedding the first paddle 23 of the rotating member 2 into the groove 35 of the fixed member 3. Subsequently, the axis of the winding post 4 needs to be aligned with the axis of the fixed member 3, and the second paddle 43 on the winding post 4 is adjusted to ensure smooth cooperation with the first paddle 23 of the rotating member 2. Finally, the arc-shaped member 5 is connected and installed with the fixing member 3. This process includes: firstly, the limiting block 32 of the fixing member 3 is embedded in the limiting hole or limiting groove 52 of the arc-shaped member 5, and then the small clamping strip 311 and the large clamping strip 312 of the fixing member 3 are respectively fixed in the small clamping groove 511 and the large clamping groove 512 corresponding to the arc-shaped member 5. It is worth noting that the arc-shaped member 5 is designed with an arc-shaped bottom plate 54, which is intended to enhance the adaptability to various shoe upper forms and improve the versatility and practicality of the product.

[0046] The retractable knob buckle of the utility model can be mainly installed on the upper of sports shoes or the waist of windbreaker, wherein the specific operation is as follows: first, the arc-shaped member 5 is installed on the object to be adjusted in tightness, such as sports shoes or windbreaker, using a button nail. Thanks to its arc-shaped design, 5 can well adapt to the contours of various objects. Next, the rope needs to pass through the traction hole 33 and be wound around the winding post 4. The rope is reinforced by the rope threading hole 41 on the winding post 4 to ensure that it is firmly connected to the winding post 4. Here, the pawl 21 equipped on the rotating member 2 has been engaged with the ratchet 34 of the fixed member 3 in the initial state, and under the action of the ratchet mechanism, the pawl 21 can only rotate in the clockwise direction.

[0047] When the requirement is to tighten the rope, the user needs to rotate the knob 1 in a clockwise direction. Because the knob 1 is fixedly connected to the rotating member 2, this operation will cause the rotating member 2 to rotate clockwise as well. It is important that the first paddle 23 on the rotating member 2 interacts with the second paddle 43 on the winding post 4, so that when the rotating member 2 rotates, the winding post 4 can be effectively driven to rotate together. This process allows the winding post 4 to wind and tighten the rope to achieve the desired tightening effect. In this process, although the friction between the ratchet and the pawl will produce a slight mechanical sound, this also enhances the user's operational feedback and usage experience to a certain extent.

[0048] When the rope needs to be loosened, the knob 1 is pulled upward. Since the knob 1 is fixedly connected to the rotating member 2, the rotating member 2 moves upward along the axis direction. At this time, the first paddle 23 on the rotating member 2 is separated from the second paddle 43 on the winding rod 4, thereby contacting the restriction on the winding rod 4, allowing it to rotate freely, and the rope is loosened. After the loosening is completed, the first paddle 23 and the second paddle 43 are re-engaged under the action of the curved portion 231.

[0049] Preferably, a mark 55 is specially provided at the bottom of the arc-shaped member 5, with the words "up" and "down" clearly marked, so that the user can intuitively identify the correct installation direction of the retracting knob buckle, and effectively avoid the possibility of incorrect installation.

[0050] Preferably, a friction pattern 14 is added to the surface of the knob 1. The design of the friction pattern 14 significantly increases the friction during operation to ensure a stable grip. The innovative lifting method is used to release the rope, rather than the traditional pressing operation. This design innovation effectively prevents the rope from loosening due to accidental touch, which not only simplifies the operation process, but also saves valuable time to a large extent.

[0051] In this embodiment, the utility model retractable knob buckle realizes one-way power transmission through a precise ratchet and pawl mechanism between the rotating part and the fixed part. That is, the rope can be quickly tightened by rotating the knob clockwise, and it can be loosened by simply lifting it up, which greatly reduces the complexity of the lacing and is easy and efficient to operate. It is particularly worth mentioning that the lifting and loosening design cleverly avoids the risk of accidental touch by the outside world, once again emphasizing its significant advantages in improving operating efficiency and saving time.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
