Description

Technical Field

[0001] This utility model relates to the technical field of twist buckles, specifically a twist buckle adapted to ropes of varying thicknesses. Background Technology

[0002] A twist-lock is a device that facilitates the adjustment of shoelace tension, commonly used in shoes with laces to allow users to quickly tighten or loosen the laces, improving lacing efficiency. However, most commercially available twist-locks are only compatible with a single lace diameter, preventing users from flexibly choosing laces of different diameters according to their preferences. Therefore, publication number CN218527874U discloses a rotating shoelace buckle suitable for both thin and thick laces. This buckle features several first threading holes (for thin laces) and second threading holes (for thick laces) on a rotating shoelace disc, with recessed grooves on the disc communicating with the second threading holes. This design facilitates the threading of laces. Users can choose the thickness of the shoelaces according to their preferences; however, in daily use, when assembling a rotating shoelace buckle into a shoe, the base is usually sewn onto the shoe first, and the other parts of the rotating shoelace buckle are pre-assembled after production to form a component, which is then installed onto the base. In the aforementioned rotating shoelace buckle that uses both thick and thin shoelaces, the rotating shoelace disc is only threaded through the base box, and there is no further limiting structure between the rotating shoelace disc and the base box. As a result, during the process of transferring the other parts of the pre-assembled rotating shoelace buckle to the installation position of the base, or when preparing to install the other parts of the rotating shoelace buckle, situations such as the rotating shoelace disc coming loose and falling off are prone to occur, affecting the normal assembly progress of the buckle.

[0003] Furthermore, the rotating shoelace buckle shared by both thick and thin shoelaces has four first threading holes. This threading structure generally requires first threading one end of the shoelace into one of the first threading holes on one side, then pulling it out from the other first threading hole on the same side, and then pulling the shoelace in the opposite direction to tighten one end of the shoelace into the second first threading hole on the same side. Then, the other end of the shoelace is threaded into the second first threading hole on the other side in the same manner. The threading method is cumbersome and time-consuming. In addition, the bottom box and the base of the rotating shoelace buckle shared by both thick and thin shoelaces are only connected by two buckle structures on the bottom box. When the user applies great force to the shoe, the bottom box is prone to detaching from the base, affecting the daily use of the buckle. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technology and provide a twisted buckle that is suitable for ropes of varying thicknesses. This twisted buckle ensures the stability of the connection between components and effectively prevents components from loosening or falling off during transfer, thereby greatly saving assembly time and ensuring smooth assembly. Its rope threading method is simple and convenient, and it can effectively guide the rope threading process, making it smoother and greatly improving the efficiency of rope threading operations and saving threading time. Moreover, it can provide storage space for knots to prevent them from getting stuck during the use of the twisted buckle, ensuring the normal daily use of the twisted buckle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A twist buckle adaptable to ropes of varying thicknesses includes a fixing base and a winding unit. The winding unit includes a top cover, a drive component snapped into the inside of the top cover, a stator connected to the drive component via a rope drum, and a clutch component snapped between the stator and the top cover. The clutch component is used to cooperate with the top cover to prevent one-way reverse rotation. The drive component is used to cooperate with the top cover to drive the rope drum to rotate and wind the rope. The clutch component is fixedly connected to the stator. The rope drum is provided with at least two sets of rope threading structures, which are used to thread at least two different rope diameters. The winding unit is connected to the fixing base via the stator.

[0007] At least two first buckles are provided in the middle of the inner side of the upper cover. The driving component is provided with a first locking position corresponding to the position of each first buckle. Each first buckle is connected to the corresponding first locking position. At least two limiting parts are formed by extending inward from the opening of the upper cover. The stator extends outward in a ring shape towards the upper cover to form a limiting edge. The limiting edge is used to cooperate with the limiting parts to prevent the upper cover from detaching from the stator.

[0008] The driving member has at least two driving teeth on the side facing the rope drum, and the rope drum has driven teeth on the side facing the driving member. When the driving member is rotated by the cover, the driven teeth cooperate with the driving teeth to drive the rope drum to rotate.

[0009] The drive unit has a through hole in the middle, and a retaining edge is provided in the annular part of the through hole. The rope drum has an elastic pin protruding on the side facing the drive unit. The elastic pin passes through the through hole and is engaged with the retaining edge.

[0010] The rope drum has an annular recess on its side to form a rope winding section, which is used to wind the rope connected to the rope drum. One side of the rope winding section has at least two thin rope holes for threading a thin rope, and the other side of the rope winding section has at least two thick rope holes for threading a thick rope. The thin rope holes and the thick rope holes form a group of rope threading structures. At least one inner side of each thin rope hole is inclined from one end to the other to form a first guide surface, and at least one inner side of each thick rope hole is inclined from one end to the other to form a second guide surface.

[0011] The side of the rope drum facing away from the drive unit has a recessed storage groove for storing rope knots. The storage groove is connected to each set of rope threading structures.

[0012] The clutch component has at least two second buckles protruding from one side, and the stator has at least two first buckles on the side facing the clutch component, with each second buckle being fastened to the corresponding first buckle.

[0013] The clutch extends outward in an arc shape on its side, forming at least two elastic arms. Each elastic arm has a clutch tooth at one end. The inner side of the upper cover is provided with a limiting tooth, which is used to cooperate with the clutch tooth to prevent the clutch from reversing in one direction when the rope is wound.

[0014] The stator has at least one latching part protruding on one side of the side facing away from the clutch, and at least one limiting block on the other side of the stator facing away from the clutch. The fixing seat has a latching hole corresponding to the position of the latching part, and the latching part is connected to the corresponding latching hole. The fixing seat has a limiting hole corresponding to the position of the limiting block, and the limiting block is connected to the corresponding limiting hole. The stator also has at least two rope-threading parts on one side, and each rope-threading part has a rope-threading hole.

[0015] The stator has at least two third buckles protruding outward on the side opposite to the clutch component. The fixed base has a first buckle hole corresponding to the position of the third buckle. Each third buckle is connected to the corresponding first buckle hole. Before the stator and the fixed base are connected, each third buckle supports the winding drum.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Through the first snap-fit ​​design of the top cover, it achieves primary pre-assembly with the drive component. The second snap-fit ​​design of the clutch component and the third snap-fit ​​design of the stator achieve primary pre-assembly between the clutch component, the stator and the winding drum, forming two sets of primary pre-assembly accessories. Combined with the elastic pin design of the winding drum, the two sets of primary pre-assembly accessories are quickly installed to complete the secondary pre-assembly and form the winding unit. Through the cooperation of primary and secondary pre-assembly, the winding unit is quickly assembled while ensuring the stability of the connection between the components of the winding unit. It can effectively prevent the components from loosening and falling off during the transfer of the winding unit, thereby greatly saving assembly time and ensuring the smooth progress of the snap-fit ​​assembly.

[0018] 2. The design of the coarse and fine rope holes on the rope reel allows for easy threading of the shoelaces. Simply thread both ends of the shoelace through either the two coarse or two fine rope holes, depending on the shoelace diameter, and tie the ends separately. Alternatively, tie the two ends side-by-side before pulling the reel onto the shoelace. This simple and convenient method saves time. Furthermore, the reel's storage slots are connected to both the coarse and fine rope holes, providing storage space for knots and preventing them from getting stuck during use. This ensures the reel's normal daily operation. Additionally, the design of the first guide surface for each fine rope hole and the second guide surface for each coarse rope hole... The faceted design effectively guides the rope threading process, making it smoother and greatly improving the efficiency of the threading operation. The third buckle design of the stator, combined with the first buckle hole of the fixed seat, effectively strengthens the stability of the connection between the stator and the fixed seat while the stator's locking part and the limiting block are connected to the fixed seat, greatly reducing the risk of the stator detaching from the fixed seat. Before the stator and the fixed seat are connected, the third buckles can also support the winding drum, providing a preliminary pre-assembly effect and preventing the winding drum from detaching from the stator during the transfer of the winding unit.

Detailed Implementation

[0032] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings:

[0033] like Figure 1-12 As shown, this utility model relates to a twist hook adapted to ropes of varying thicknesses, comprising a fixing base 1 and a winding unit 2. The winding unit 2 includes an upper cover 21, a driving member 22 snapped into the inner side of the upper cover 21, a stator 24 connected to the driving member 22 via a rope drum 23, and a clutch 25 engaged between the stator 24 and the upper cover 21. The clutch 25 is used to cooperate with the upper cover 21 to prevent one-way reverse rotation. The driving member 22 is used to cooperate with the upper cover 21 to drive the rope drum 23 to rotate and wind the rope. The clutch 25 is fixed to the stator 24. The winding drum 23 is provided with at least two sets of rope threading structures, which are used to thread ropes of at least two different diameters. The winding unit 2 is connected to the fixed seat 1 through the stator 24. The bottom surface of the fixed seat 1 is arc-shaped. The arc bending direction of the fixed seat 1 can be configured according to the position of the shoe (such as the side of the shoe or the tongue of the shoe) required by this invention, and is not limited here. The lower end of the fixed seat 1 extends outward to form a connecting part 15, which is used to connect with the shoe body.

[0034] like Figure 1-3As shown in Figure 11, at least two first buckles 211 are provided in the middle of the inner side of the upper cover 21. The driving member 22 is provided with a first locking position 221 corresponding to the position of each first buckle 211. Each first buckle 211 is connected to the corresponding first locking position 221. Through the cooperation of each first buckle 21 and the corresponding first locking position 221, the initial pre-assembly between the components is realized, so that the two components form a stable connection. At least two limiting parts 212 are formed inwardly at the opening of the upper cover 21. The stator 24 extends outward in a ring towards the upper cover 21 to form a limiting edge 241. The limiting edge 241 is used to cooperate with the limiting parts 212 to prevent the upper cover 21 from detaching from the stator 24.

[0035] like Figure 2 , 4 As shown in Figure 12, the driving member 22 has at least two driving teeth 222 on the side facing the rope drum 23, and the rope drum 23 has a driven tooth 231 on the side facing the driving member 22. When the driving member 22 is rotated by the cover 21, the driven tooth 231 cooperates with the driving teeth 222 to drive the rope drum 23 to rotate.

[0036] like Figure 2 , 4 As shown in Figure 12, the driving member 22 has a through hole 223 in the middle, and a retaining edge 224 is provided in the annular part of the through hole 223. The rope drum 23 has an elastic pin 232 protruding on the side facing the driving member 22. The elastic pin 232 passes through the through hole 223 and is engaged with the retaining edge 224.

[0037] like Figure 2 , 7As shown in Figures 9 and 12, the rope drum 23 has an annular recess on its side, forming a rope winding section 233. This section is used to wind the rope connected to the rope drum 23. One side of the section has at least two thin rope holes 234 for threading a thin rope. The other side has at least two thick rope holes 235 for threading a thick rope. The thin rope holes 234 and the thick rope holes 235... The system comprises a group of rope-threading structures, wherein at least one inner side of each rope hole 234 is inclined from one end to the other, forming a first guide surface 234a. This first guide surface 234a effectively guides the rope threaded through the rope hole 234, making the rope threading through the rope hole 234 smoother and greatly improving the efficiency of the rope-threading operation. Specifically, when there are two rope holes 234, each rope hole 234... When each of the four first guide surfaces 234a is surrounded by a small hole, the small hole 234 has an approximately square funnel-shaped structure, and the connection between each first guide surface 234a is rounded. Each of the small holes 234 is symmetrically arranged on the rope drum 23. At least one side of the inner surface of each large hole 235 is inclined from one end to the other to form a second guide surface 235a. The second guide surface 235a can effectively guide the rope passing through the large hole 235, making the rope pass through the large hole 235 more smoothly and greatly improving the efficiency of rope threading. Specifically, when there are two large holes 235, each of the large holes 235 is surrounded by four second guide surfaces 235a, the large hole 235 has an approximately square funnel-shaped structure, and the connection between each second guide surface 235a is rounded. Each of the large holes 235 is symmetrically arranged on the rope drum 23.

[0038] like Figure 7 , 12 As shown, the side of the rope drum 23 facing away from the drive member 22 is recessed with a storage groove 236. The storage groove 236 is used to store the knot of the rope. The storage groove 236 is connected to each group of rope threading structures.

[0039] like Figure 2 , 5As shown, the clutch 25 has at least two second buckles 251 protruding from one side, and the stator 24 has at least two first fastening positions 242 on the side facing the clutch 25. Each of the second buckles 251 is fastened to the corresponding first fastening position 242. By cooperating with each of the second buckles 251 and the corresponding first fastening position 242, the initial pre-assembly between the components is realized, so that the two components form a stable connection. The stator 24 has a connecting hole 248 on the side facing the clutch 25. The connecting hole 248 provides clearance space for the elastic pin 232 of the rope drum 23 and the driving member 22, so that the driving member 22 can pass through the connecting hole 248, extend into the inside of the stator 24, and engage with the driven tooth 231 of the rope drum 23. The aforementioned first fastening positions 242 are respectively provided at the edge of the connecting hole 248.

[0040] like Figure 2 , 5 As shown, the clutch 25 extends outward in an arc shape, forming at least two elastic arms 252. Each elastic arm 252 has a clutch tooth 253 at one end. The inner side of the upper cover 21 is provided with a limiting tooth 213. The limiting tooth 213 is used to cooperate with the clutch tooth 253 to prevent the clutch 25 from reversing in one direction when the rope is wound. Specifically, each limiting tooth 213 or clutch tooth 253 is a triangular structure with one side being a slope and the other side being a vertical surface. When the limiting tooth 213 and the corresponding clutch tooth 253 are engaged, the inclined surface of each limiting tooth 213 contacts the inclined surface of the corresponding clutch tooth 253. When the upper cover 21 is rotated, each clutch tooth 253 is passively transitioned along the inclined surface of the engaged limiting tooth 213 to contact the inclined surface of another limiting tooth 213. At this time, since the vertical surface of each limiting tooth 213 is also in contact with the vertical surface of the corresponding clutch tooth 253, a one-way anti-reverse effect is achieved.

[0041] like Figure 1 , 2 As shown in Figures 6 and 10, at least one engaging portion 243 protrudes from one side of the stator 24 facing away from the clutch 25, and at least one limiting block 244 is provided on the other side of the stator 24 facing away from the clutch 25. A engaging hole 11 is provided on the fixing base 1 corresponding to the engaging portion 243, and the engaging portion 243 is connected to the corresponding engaging hole 11. A limiting hole 12 is provided on the fixing base 1 corresponding to the limiting block 244, and the limiting block 244 is connected to the corresponding limiting hole 12. In the middle, the stator 24 is provided with at least two rope-threading parts 245 on one side, and each rope-threading part 245 is provided with a rope-threading hole 246; the fixing base 1 is recessed with a mounting groove 14, and the aforementioned snap-fit ​​hole 11 and limiting hole 12 are respectively provided in the mounting groove 14. A first stop 111 is formed on the inner side of the snap-fit ​​hole 11, and the first stop 111 is used to limit the snap-fit ​​part 243. A second stop 121 is formed on the inner side of the limiting hole 12, and the second stop 121 is used to limit the limiting block 244.

[0042] like Figure 1 , 2 As shown in Figure 6, the stator 24 has at least two third buckles 247 protruding outward on the side facing away from the clutch 25. The fixed base 1 has a first buckle hole 13 corresponding to the position of the third buckle 247. Each of the third buckles 247 is connected to the corresponding first buckle hole 13. The cooperation between each of the third buckles 247 and the first buckle hole 13 can effectively enhance the stability of the connection between the stator 24 and the fixed base 1, and greatly reduce the risk of the stator 24 falling off the fixed base 1. Before the stator 24 is connected to the fixed base 1, each of the third buckles 247 supports the rope drum 23, which has the effect of primary pre-assembly of the components to prevent the rope drum 23 from falling off the stator 24 at will.

[0043] It should be noted that during the pre-assembly process, the primary pre-assembly between the upper cover 21 and the drive component 22, and the primary pre-assembly between the clutch component 25, the stator 24, and the winding drum 23, respectively form two sets of primary pre-assembly components. After the elastic pin 232 on the winding drum 23 passes through the through hole 223 of the drive component 22, and is limited by the retaining edge 224, the two sets of primary pre-assembly components can be quickly installed, completing the secondary pre-assembly and forming the winding unit 2. When threading the rope, it is generally necessary to consider the diameter of the shoelace. Rotate each thin rope hole or each thick rope hole to the corresponding rope hole of the rope threading part, so that each thin rope hole or each thick rope hole is connected to the corresponding rope threading hole. Then, thread one end of the rope through one of the rope threading holes and the thin rope hole or the thick rope hole, and pull it out from the storage groove. Then, thread the other end of the rope through the rope threading hole and the thin rope hole or the thick rope hole, and pull it out from the storage groove. Then, tie knots at both ends of the rope, or tie knots at both ends of the rope side by side. Then, pull the rope in the opposite direction so that the knotted part enters the storage groove 236, thus completing the assembly of the rope in the winding unit 2.

[0044] When used on a shoe body, the fixing seat 1 is usually fixed to the shoe body first (such as on the side or tongue of the shoe). Specifically, the fixing seat 1 is pre-set on the shoe body, and then the connecting part 15 of the fixing seat 1 is sewn along the sewing thread to fix the connecting part 15 to the shoe body. Then, the snap-fit ​​part 243 of the stator 24 is inserted into the snap-fit ​​hole 11 of the fixing seat 1. Then, force is applied to the side of the upper cover 21 corresponding to the limiting block 244 to press the present invention downward, so that the limiting block 244 of the stator 24 snaps into the limiting hole 12 of the fixing seat 1. At the same time, each of the third buckles 247 is snapped into the corresponding first buckle hole 13 of the fixing seat 1, thus completing the installation between the winding unit 2 and the fixing seat 1.

[0045] In the normal state of this utility model, each limiting part 212 of the upper cover 21 is close to the fixed base 1. At this time, each driving tooth 222 of the driving member 22 meshes with the driven tooth 231 corresponding to the winding drum 23, and each clutch tooth 253 of the clutch member 25 meshes with the corresponding limiting tooth 213.

[0046] When the rope needs to be wound, the top cover 21 only needs to be rotated in one direction. At this time, the top cover 21 drives the drive member 22 to rotate. The drive member 22 acts on the driven tooth 231 of the rope drum 23 through the drive tooth 222, so that the rope drum 23 rotates with the drive member 22, and the rope is gradually wound around the inside of the rope winding part 233. 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 the rope is wound, since each clutch tooth 253 of the clutch member 25 meshes with the corresponding drive tooth 222 in the top cover 21, during the rotation of the top cover 21, each clutch tooth 253 switches with each limiting tooth 213. And due to the anti-reverse action of the limiting tooth 213 on each clutch tooth 253, the rope is prevented from coming loose from the rope drum 23.

[0047] When the rope needs to be released, simply lift the top cover 21 from the stator 24, so that each limiting part 212 of the top cover 21 approaches the limiting edge 241. At this time, as the top cover 21 is lifted, each driving tooth 222 separates from the driven tooth 231 corresponding to the rope drum 23, and each clutch tooth 253 of the clutch 25 separates from the corresponding limiting tooth 213. This releases the linkage between each driving tooth 222 and the driven tooth 231, and between each clutch tooth 253 and the limiting tooth 213. The limiting tooth 213 no longer engages with each clutch tooth 253, so the rope can be released and the shoelaces can be loosened, thereby restoring the original space inside the shoe and making it easier to remove the shoe from the foot.

[0048] 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.
