Detailed Implementation

[0047] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings: like Figure 1-29 As shown, this utility model relates to a winding structure for a snap fastener, including a stator 1 and a winding member 2 disposed within the stator 1. The stator 1 is connected to a fixing seat 4 of the snap fastener, and the winding member 2 is used to wind a rope. The winding structure also includes a cover assembly 3, which is disposed on the stator 1 and connected to the winding member 2 via at least one pin P. The cover assembly 3 drives the winding member 2 to rotate during the winding of the snap fastener. The stator 1 has a first clearance hole 11 at the connection point with the cover assembly 3. The cover assembly 3 includes a first component 31 and a second component 32 disposed on the first component 31. The inner side of the first component 31 has a... At least two anti-reverse parts 311 are provided. The inner side of the stator 1 facing the first component 31 is provided with a plurality of limiting teeth 12. Each limiting tooth 12 is used to cooperate with each anti-reverse part 311 to prevent one-way reversal. Each limiting tooth 12 is arranged around the opening of the first clearance hole 11. The pin part P is composed of at least two pin units P1. A gap is formed between each pin unit P1. Each pin unit P1 has a limiting protrusion P2 on the outer side of one end. Each limiting protrusion P2 cooperates with each other to prevent the face cover assembly 3 and the winding member 2 from loosening at will, and to ensure the stability of the connection between the face cover assembly 3 and the winding member 2. The aforementioned rope is used to tighten or loosen the shoe upper.

[0048] Furthermore, such as Figure 3 , 4As shown in 7-21, each of the aforementioned anti-reverse parts 311 is composed of an elastic arm 311a and an anti-reverse tooth 311b provided at one end of the elastic arm 311a. Each anti-reverse tooth 311b cooperates with the limiting tooth 12 on the stator 1 to unidirectionally prevent the first component 31 from rotating in one direction and to arbitrarily reset the first component 31.

[0049] like Figure 3-5 As shown in Figure 9, a first through hole 21 is provided in the middle of the winding component 2, and a pin P is provided in the middle of the side of the first component 31 of the cover assembly 3 facing the winding component 2. The pin P passes through the first clearance hole 11 of the stator 1 and is inserted into the first through hole 21.

[0050] Or, such as Figure 3-5 As shown in Figure 10-21, a first through hole 21 is provided in the middle of the winding component 2, and a pin P is provided in the middle of the side of the second component 32 of the cover assembly 3 facing the winding component 2. A second clearance hole 312 is provided in the middle of the first component 31 of the cover assembly 3. The pin P passes through the first clearance hole 11 of the stator 1 and the second clearance hole 312 of the first component 31 and is inserted into the first through hole 21.

[0051] Or, as Figure 6 , 10 As shown in -21, the pin P is located in the middle of the side of the winding member 2 facing the cover assembly 3. The first component 31 of the cover assembly 3 has a second through hole 313 in the middle. The pin P passes through the first clearance hole 11 of the stator 1 and is inserted into the second through hole 313.

[0052] like Figure 5 , 6 As shown in 9, 11, 13, 19, and 21, the winding member 2 is provided with at least two driven teeth 22 on the side facing the stator 1, and the anti-reverse portion 311 of the first component 31 of the cover assembly 3 is provided with at least two first driving teeth 314 on the side facing the winding member 2. Each of the first driving teeth 314 is used to cooperate with the driven teeth 22 to drive the winding member 2 to rotate during the winding.

[0053] Or, such as Figure 5 , 6 As shown in Figures 25 and 26, the winding member 2 has at least two driven teeth 22 on the side facing the stator 1, and the second component 32 of the cover assembly 3 has at least two second drive teeth 321 on the side facing the winding member 2. The second drive teeth 321 are used to cooperate with the driven teeth 22 to drive the winding member 2 to rotate during the winding.

[0054] When the user rotates the face cover assembly 3, the first drive tooth 314 / second drive tooth 321 and driven tooth 22 cooperate to drive the winding member 2 to rotate, and the rope is wound around the winding member 2.

[0055] like Figure 7-13As shown in Figures 22-24, the second component 32 is a one-piece structure. The side of the second component 32 facing the first component 31 is provided with at least two claws 322. The first component 31 is provided with corresponding holes 315 for each claw 322. Each claw 322 is connected to the corresponding hole 315 to engage and embed the second component 32 onto the first component 31. Through the cooperation of each claw 322 with the hole 315, in addition to connecting the first component 31 and the second component 32, it can also effectively ensure that the first component 31 and the second component 32 rotate synchronously when the cover component 3 of the rotating buckle is rotated.

[0056] Or, such as Figure 16 , 17 As shown in Figure 26, the second component 32 is a one-piece structure. The side of the second component 32 facing the first component 31 has at least two extension sections 323 protruding. At least one external buckle 323a protrudes from one end of each extension section 323. The anti-reverse portion 311 of the first component 31 has a corresponding buckle 316. Each external buckle 323a engages with the corresponding buckle 316 to fix the second component 32 onto the first component 31. Through the cooperation of each external buckle 323a with the buckle 316, in addition to connecting the first component 31 and the second component 32, it can also effectively ensure that the first component 31 and the second component 32 rotate synchronously when the cover component 3 with the rotating buckle is rotated.

[0057] Or, such as Figure 12-15 As shown in Figures 24 and 25, the second component 32 is a cover structure. The inner wall of the second component 32 is provided with at least two buckles 324 near the opening. The edge of one side of the first component 31 is provided with a locking position 317 corresponding to each buckle 324. Each buckle 324 is connected to the corresponding locking position 317 to snap the second component 32 onto the first component 31. Through the cooperation of each buckle 324 and the locking position 317, in addition to connecting the first component 31 and the second component 32, it can also effectively ensure that when the cover component 3 with the rotating buckle is rotated, the first component 31 and the second component 32 rotate synchronously.

[0058] Or, as Figure 18-21 As shown in Figure 27, the second component 32 is a cover structure. The inner wall of the second component 32 is provided with at least two threaded grooves 325 near the opening. The outer side of the first component 31 is provided with external threads 318 corresponding to each threaded groove 325. Each threaded groove 325 is threadedly connected to the corresponding external thread 318, so that the second component 32 is sleeved on the first component 31. Through the cooperation of each external thread 318 with the threaded groove 325, in addition to realizing the connection between the first component 31 and the second component 32, it can also effectively ensure that when the cover component 3 with the rotating buckle is rotated, the first component 31 and the second component 32 rotate synchronously.

[0059] It should be noted that the synchronous rotation of the first component 31 and the second component 32 can effectively ensure the transmission between the first drive tooth 314 / second drive tooth 321 and the driven tooth 22. This ensures that whether it is the first drive tooth 314 on the first component 31 or the second drive tooth 321 on the second component 32, when the cover component 3 is rotated, the winding member 2 will rotate by driving the driven tooth 22, thereby enabling the winding member 2 to wind the rope.

[0060] like Figure 7 , 8 As shown in 10, 16, 17, 22, 23, and 26, the second component 32 facing the first component 31 is also provided with at least one anti-mistake protrusion 326. The first component 31 is provided with at least one anti-mistake hole 319 corresponding to the anti-mistake protrusion 326. The anti-mistake protrusion 326 is connected to the anti-mistake hole 319. The setting of the anti-mistake protrusion 326 and the anti-mistake hole 319 effectively ensures that each claw 322, external protrusion buckle 323a, buckle 324 or threaded groove 325 can be more easily and accurately connected to the corresponding buckle hole 315, buckle position 316, buckle position 317 or external thread 318, thereby improving the assembly efficiency between components and improving the accuracy of component assembly.

[0061] like Figure 1-6 As shown, the stator 1 has a plug-in portion 13 on one side facing the fixed base 4, and a snap-fit ​​portion 14 on the other side facing the fixed base 4. The fixed base 4 has a mounting groove 41, and a plug-in hole 42 is provided in the mounting groove 41 corresponding to the plug-in portion 13. The plug-in portion 13 is inserted into the plug-in hole 42. The mounting groove 41 has a snap-fit ​​hole 43 corresponding to the snap-fit ​​portion 14, and the snap-fit ​​portion 14 is snapped into the snap-fit ​​hole 43. The winding structure is installed in the mounting groove 41 of the fixed base 4. The stator 1 has at least two rope-threading holes 15, each of which is used to thread rope through... The rope to be wound is provided. The side of the winding member 2 is recessed with a winding part 23. At least two rope-connecting holes 24 are provided on the winding part 23. Each rope-connecting hole 24 is used to bind the rope end of the rope. The lower end of the fixing base 4 extends outward to form a connecting part 44. The connecting part 44 is used to connect with the shoe body. In addition, the top edge of the stator 1 is provided with a limiting edge 16 protruding outward. The aforementioned first component 31 is provided with at least two limiting blocks 31a on the inner side of one end facing the stator 1. Each limiting block 31a cooperates with the limiting edge 16 to prevent the first component 31 from being arbitrarily loosened from the stator 1 after it is fitted onto the stator 1.

[0062] In daily applications, this invention is typically pre-assembled. First, the ends of the rope already attached to the shoe body are passed through the corresponding rope holes 15 on the stator 1. Then, each rope end is passed through the rope receiving hole 24 of the winding member 2 and knotted for fixation. Next, the stator 1 is fitted onto the outside of the winding member. Then, the faceplate assembly 3 and the winding member 2 are connected via the pin P to form a winding structure. Then, the fixing seat 4 is fixed to the shoe body (e.g., on the side or tongue). Specifically, the fixing seat 4 is pre-installed on the shoe body, and then sewn along the connecting portion 44 of the fixing seat 4 to fix the connecting portion 44 to the shoe body. Then, as... Figure 2 As shown, the winding structure is tilted on the fixing base 4, and the insertion part 13 of the stator 1 is inserted into the insertion hole 42 of the fixing base 4. Then, force is applied to the side of the second component 32 of the cover assembly 3 corresponding to the stator 1 where the snap-fit ​​part 14 is provided, and the present invention is pressed down so that the snap-fit ​​part 14 of the stator 1 is snapped into the snap-fit ​​hole 43 of the fixing base 4, thus completing the overall installation of the screw fastener.

[0063] In the normal state of this utility model, each limiting block 31a of the first component 31 of the cover assembly 3 is far away from the limiting edge 16 of the stator 1. At this time, each first driving tooth 314 of the first component 31 and each second driving tooth 321 of the second component 32 respectively mesh with the driven tooth 22 corresponding to the winding member 2, and each anti-reverse part 311 of the first component 31 respectively meshes with the corresponding limiting tooth 12 on the stator 1.

[0064] When it is necessary to wind the rope, only one-way rotation of the cover assembly 3 is required. At this time, each first drive tooth 314 of the first assembly 31 and each second drive tooth 321 of the second assembly 32 drive the winding member 2 to rotate by acting on the driven tooth 22. The winding member 2 rotates with the cover assembly 3, and the rope is gradually wound around the inside of the winding part 23 of the winding member 2. As the rope is wound, the rope connected to the shoe is continuously shortened, and the position of the shoelace on the shoe body is gathered, thereby reducing the space inside the shoe body and making the shoe body fit the foot more stably. It should be noted that when winding the rope, since the anti-reverse tooth 311b of the anti-reverse part 311 of the first assembly 31 meshes with the limiting tooth 12 on the stator 1, during the rotation of the cover assembly 3, each anti-reverse tooth 311b switches with each limiting tooth 12. And due to the anti-reverse action of the limiting tooth 12 on each anti-reverse tooth 311b, the rope is prevented from coming loose from the winding member 2.

[0065] When the rope needs to be released, simply lift the faceplate assembly 3 from the stator 1, so that each limiting block 31a of the first assembly 31 approaches the limiting edge 16 of the stator 1. At this time, each first driving tooth 314 of the first assembly 31 and each second driving tooth 321 of the second assembly 32 are separated from the driven tooth 22 corresponding to the winding member 2 as the faceplate assembly 3 is lifted. Each anti-reverse part 311 is separated from the corresponding limiting tooth 12, thereby releasing the meshing / linkage relationship between each first driving tooth 314 / second driving tooth 321 and the driven tooth 22, and between each anti-reverse part 311 and the limiting tooth 12. The limiting tooth 12 no longer limits the anti-reverse tooth 311b of each anti-reverse part 311, so the rope can be released and the shoelaces on the shoe body can be loosened, thereby restoring the original space inside the shoe body, so that the shoe body can be removed from the foot.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
