Description

Technical Field

[0001] This utility model relates to the field of rotating shoe buckle technology, specifically to a stable rotating buckle. Background Technology

[0002] Currently, some shoelaces use a rotating buckle for locking. Generally, you rotate and press the lace buckle. Through the setting of the inlet hole, the bottom of the shoelace can be fixed inside the take-up device, making it easy to wind up the shoelace. Through the setting of the inlet protrusion, the shoelace can be wound up to adjust the tightness of the shoe upper and ensure the comfort of the foot.

[0003] The existing buckle structure is generally only used in some children's shoes, mainly because the existing buckle structure cannot guarantee the overall stability of the buckle. At the same time, when tightening the shoelaces, the shoelaces are prone to slipping, thus failing to lock them securely. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a stable rotary locking device, which addresses the shortcomings mentioned in the aforementioned Beijing technology.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a sturdy rotating lock buckle includes a fixed base, a mounting seat is fixedly attached to the top of the fixed base, an I-shaped take-up retractor is limited inside the mounting seat, a positioning component that can drive the take-up retractor to rotate is provided on the top of the mounting seat, a rotating top cover is fixedly attached to the top of the positioning component, a limiting placement groove for placing the take-up retractor is provided inside the mounting seat, and the middle part of the take-up retractor and the inner wall of the limiting placement groove form a take-up space;

[0006] The mounting base has symmetrical inlet holes on both sides of the front end for cooperating with the take-up device. The take-up device has symmetrical winding holes on both sides that are aligned with the inlet holes. The winding holes have three winding through holes that penetrate the take-up device.

[0007] The mounting base is provided with a positioning rack ring on the inner side of the top, and multiple elastic strips are evenly provided on the outer side of the positioning element. The outer end of the elastic strip is engaged with the anti-reverse teeth of the positioning rack ring.

[0008] The take-up device has a positioning hole in the middle, and the positioning component has a positioning center shaft at the bottom. The positioning center shaft is inserted into the positioning hole to ensure that the positioning component is stably set. The top of the limiting placement groove has a through hole.

[0009] Furthermore, the top of the fixed base is provided with a sleeve wall for attaching the mounting seat, the bottom of the inner side of the fixed base is provided with multiple first snap-fit ​​grooves, the outer side of the mounting seat is provided with a first snap that matches the first snap-fit ​​grooves, and the front side of the sleeve wall is provided with a groove that matches the inlet hole.

[0010] Furthermore, the top of the take-up device is provided with a positioning annular tooth groove outside the insertion positioning hole. The positioning annular tooth groove is composed of multiple triangular positioning grooves, and the bottom of the positioning component is provided with a positioning tooth ring that matches the positioning annular tooth groove.

[0011] Furthermore, the positioning center shaft is composed of two symmetrically arranged elastic elements with a gap between them. The center of the insertion positioning hole is provided with a first positioning protrusion ring, and the outer side of the bottom of the elastic element is provided with a protruding end that cooperates with the first positioning protrusion ring.

[0012] Furthermore, the mounting base has a wire support structure corresponding to the inlet hole on its outer side.

[0013] Furthermore, the positioning component has a second snap-fit ​​groove on its inner side, the rotating top cover has a second snap-fit ​​groove on its inner bottom side, the mounting base has a second positioning protrusion ring on its top outer side, and the rotating top cover has a positioning snap-fit ​​ring on its inner bottom side that matches the second positioning protrusion ring.

[0014] Furthermore, the bottom of the fixed base is flat.

[0015] The advantages of this utility model compared with the prior art are: improved locking stability and expanded applicable scenarios: by setting three winding through holes for the take-up device in the winding hole, and in combination with the cross-threading method of the shoelaces, the contact area and friction between the shoelaces and the take-up device are increased, effectively reducing the risk of shoelaces slipping and loosening; compared with the existing rotating buckle that is only suitable for children's shoes, this application can be adapted to scenarios with higher requirements for locking reliability, such as sports shoes.

[0016] Balancing stability and ease of operation: The positioning center shaft adopts a double elastic element structure, which, together with the first positioning convex ring in the positioning hole, ensures the stability of the positioning element during daily use by engaging the convex end with the convex ring; when the line needs to be loosened, only external force needs to be applied to contract the elastic element to pull out the positioning element, making operation convenient.

[0017] Combining anti-rotation and flexible transmission: The cooperation between the positioning rack ring and the elastic anti-rotation teeth can limit the rotation of the positioning component after the line is taken in, ensuring a locked state; the opposite tooth direction design of the positioning ring groove and the positioning ring not only achieves synchronous transmission during line take-up, but also allows the take-up device to rotate when the line is loosened by the teeth disengaging, improving the flexibility of use.

[0018] Easy to assemble and maintain, and protects shoelaces: The components are detachably connected by buckles, protruding rings and other structures, which facilitates production assembly and subsequent maintenance; the arc-shaped guide frame structure on the outside of the mounting base can guide the shoelaces and reduce wear during the shoelace threading and winding process.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Combined with appendix Figure 1-4 A type of swivel lock includes a fixed base 1. The bottom of the fixed base 1 is flat to facilitate a tight fit between the device and the attachment. A mounting seat 2 is fixedly attached to the top of the fixed base 1. An I-shaped retractor 3 is provided inside the mounting seat 2. A positioning element 4 is provided on the top of the mounting seat 2 to drive the retractor 3 to rotate. A rotating top cover 5 is fixedly attached to the top of the positioning element 4. A limiting placement groove 22 is provided inside the mounting seat 2 for placing the retractor 3. The middle part of the retractor 3 and the inner wall of the limiting placement groove 22 form a retracting space 6, in which the wound shoelace can be stored.

[0026] The mounting base 2 has symmetrically arranged inlet holes 23 on both sides of its front end to accommodate the take-up coil 3. The take-up coil 3 has symmetrically arranged winding holes 33 on both sides to align with the inlet holes 23. Each winding hole 33 has three through-holes 34 that penetrate the take-up coil 3.

[0027] Conventional rotating shoe buckles typically have a single-hole structure, meaning they only have two symmetrical holes. However, when winding the thread around these two holes, because the thread surface is relatively smooth, one hole may loosen during the tightening process. But now, with three through-holes 34 of the thread take-up device 3, the thread is crisscrossed back and forth, ensuring greater stability and a firmer grip during rotation, preventing loosening. Previous buttons were only suitable for children's shoes, but this new structure allows them to be used in athletic shoes, such as basketball shoes, tennis shoes, and badminton shoes, without worrying about loosening.

[0028] The take-up coil 3 has a positioning hole 31 in the middle, and the positioning member 4 has a positioning center shaft 41 at its bottom. The positioning center shaft 41 is inserted into the positioning hole 31 to ensure the positioning member 4 is stably set. The limiting placement groove 22 has a through hole 25 at its top. The positioning center shaft 41 is composed of two symmetrically arranged elastic members with a gap between them. The center of the insertion into the positioning hole 31 has a first positioning protrusion ring 35 in the middle, and the outer side of the bottom of the elastic member has a protruding end that matches the first positioning protrusion ring 35. Compared with the traditional interference fit, this application sets two... The elastic element with gaps between them is made of elastic material. The protruding end of the elastic element cooperates with the first positioning protrusion ring 35 to ensure the stability of the top positioning element 4 and the rotating cover 5 in daily use when inserted into the positioning hole 31. The rotating cover 5 can only be pulled out by force when the wire needs to be loosened. That is, in normal operation, the protruding end of the elastic element is located below the first positioning protrusion ring 35, thereby achieving a stable effect. When the wire needs to be loosened, the rotating cover 5 is pulled out by force, and the two elastic elements will retract towards the middle, so that it can be pulled out. The same principle applies when pressing down on the rotating cover 5.

[0029] The mounting base 2 has a positioning rack ring 24 on its top inner side, and the positioning member 4 has a plurality of elastic strips 42 evenly distributed on its outer side. The ends of the elastic strips 42 are engaged with the anti-backward teeth 43 of the positioning rack ring 24. The inclined surface of the anti-backward teeth 43 is in contact with the inclined surface of the positioning rack ring 24. That is, when the wire is rotated and wound up, the inclined surface is forced outward by the rotation force, and then the multiple elastic strips 42 retract inward. When the rotation is in place, the multiple elastic strips 42 pop outward. The anti-backward teeth 43 can ensure that the positioning member 4 will not rotate back.

[0030] The top of the take-up reel 3 is provided with a positioning annular groove 32 outside the insertion positioning hole 31. The positioning annular groove 32 is composed of multiple triangular positioning grooves. The bottom of the positioning component 4 is provided with a positioning toothed ring 45 that matches the positioning annular groove 32. The inclined surface of the positioning groove 32 contacts the inclined surface of the positioning annular groove 32. The tooth direction here is opposite to the tooth direction of the positioning rack ring 24 that matches the upward release tooth 43. Thus, when the rotating cover 5 and the positioning component 4 are rotated, the positioning component 4 will drive the take-up reel 3 to rotate for take-up operation. When it is necessary to take up the line, the rotating cover 5 and the positioning component 4 can be pulled upward to disengage the positioning annular groove 32 from the positioning toothed ring 45, so that the take-up reel 3 can rotate back and achieve the effect of loosening the line.

[0031] The positioning component 4 has a second latching groove 44 on its inner side, and the rotating top cover 5 has a second latch 51 that matches the second latching groove 44 at its inner bottom. The second latching groove 44 and the second latch 51 can be used to easily fix the rotating top cover 5 and the positioning component 4. The mounting base 2 has a second positioning protrusion ring 27 on its top outer side, and the rotating top cover 5 has a positioning latch 52 that matches the second positioning protrusion ring 27 at its inner bottom. The second positioning protrusion ring 27 and the positioning latch 52 can prevent the rotating top cover 5 and the positioning component 4 from easily detaching from the mounting base 2 when they are pulled out, thus improving safety.

[0032] The fixed base 1 has a sleeve wall 11 at its top for attaching to the mounting base 2. The fixed base 1 has multiple first snap-fit ​​grooves 13 at the bottom of the inner side of the sleeve wall 11. The mounting base 2 has a first snap 21 on its outer side that matches the first snap-fit ​​grooves 13. The first snap-fit ​​grooves 13 and the first snap 21 facilitate the fixing and snapping of the fixed base 1 and the mounting base 2. The sleeve wall 11 has a groove 12 on its front side that matches the inlet hole 23. The mounting base 2 has a wire frame structure 26 on its outer side corresponding to the inlet hole 23. The size of the groove 12 also needs to match the wire frame structure 26, as shown in the figure. The outer side of the wire frame structure 26 is arc-shaped, which can guide the shoelaces, reduce wear during shoelace threading and winding, and extend the service life of the shoelaces.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
