Description

Technical Field

[0001] This utility model relates to the field of shoe buckle technology, specifically a metal shoe buckle with a locking mechanism. Background Technology

[0002] Shoe buckles are accessories used to fasten, decorate, or adjust the tightness of footwear. They are widely used in various shoe types, including leather shoes, athletic shoes, boots, and dress shoes. They not only serve a functional purpose but also enhance the design and style of the shoes. Shoe buckles are typically used to secure two separate shoelaces. They usually have a locking part and a finishing part. The locking part has a locking hole for threading and locking the shoelace, while the finishing part has a finishing hole. Due to the limitations of their structure, shoelace buckles can make it difficult to thread excessively long or thick shoelace ends through the locking holes, leading to operational difficulties. This can impair the performance of the locking mechanism, reduce the buckle's locking effect on the shoelace, and consequently, severely impact the practicality of the buckle, as well as the lifespan and appearance of the shoelace ends.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202221860103.1, application date 2020-04-14) provides a novel shoe buckle, including a tail section and a locking section. A groove is provided in the middle of the outer side of the tail section. A rotating plate is evenly and movably connected to the inner cavity of the groove. A baffle is evenly and fixedly connected to the inner cavity of the groove, and the baffle contacts one side of the rotating plate. Fixed plates are provided at the top and bottom of the outer side of the groove. The locking section includes a U-shaped clip adapted to the groove. A limiting groove adapted to the rotating plate is evenly provided on one side of the U-shaped clip, and a handle is fixedly connected to the middle of the other side of the U-shaped clip. This novel shoe buckle, with its locking section, is fixed to the strap by clamping with a clamping piece, allowing for quick fixing or separation of the strap and the locking section, facilitating the assembly and disassembly of the shoe buckle. Furthermore, the material of the clamping piece allows the top of the clamping piece to deflect, enabling the locking section to adapt to straps of various thicknesses, thus improving the practicality of the shoe buckle.

[0004] Untied shoelaces can cause tripping while walking or exercising, especially in crowded places or during fast-moving activities. This can lead to falls and injuries. Furthermore, users need to stop frequently to retie their shoelaces during walking or exercising. The aforementioned device cannot lock the shoelaces in place, causing them to loosen frequently. It also weakens the shoe's support and fit, allowing the foot to slide inside the shoe and leading to fatigue or injury to the foot and leg muscles. Utility Model Content

[0005] The purpose of this invention is to provide a metal shoe buckle with a locking mechanism to solve the problems mentioned in the background art, such as the inability to achieve self-locking of shoelaces, which leads to frequent loosening of shoelaces, weakened shoe support and wrapping of the foot, and slippage of the foot inside the shoe, resulting in foot and leg muscle fatigue or injury.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: By using the connecting rod 10, sliding groove 12, and locking block 18, the stability of the device during operation is improved, allowing the tension on the shoelace 3 to be evenly distributed to various parts of the shoe buckle 1 through the sliding groove 12 and connecting rod 10. Figures 1-2 As shown: It includes a shoe buckle 1, a rotating shaft 2 is rotatably arranged inside the shoe buckle 1, and a ratchet 5 is fixedly connected to the surface of the rotating shaft 2. The ratchet 5 is rotatably arranged inside the shoe buckle 1. At the same time, a drive shaft 8 is rotatably arranged inside the shoe buckle 1, and a pawl 9 is fixedly connected to the surface of the drive shaft 8. The pawl 9 is rotatably arranged inside the shoe buckle 1, and the pawl 9 and the ratchet 5 are engaged inside the shoe buckle 1. A connecting rod 10 is fixedly connected to the surface of the pawl 9, and the connecting rod 10 is slidably arranged inside the shoe buckle 1. A pull rod 11 is fixedly connected to the surface of the connecting rod 10. At the same time, a sliding groove 12 is opened inside the pull rod 11, and a locking block 18 is slidably connected to the surface of the sliding groove 12.

[0029] The wearer threades the shoelace 3 through the corresponding eyelet on the buckle 1, and adjusts the tightness of the shoelace 3 by pulling the pull ring 4 on its surface. Once the fit is comfortable, the wearer releases the pull ring 4. At this point, the pawl 9 and ratchet 5 inside the buckle 1 engage, locking the shoelace 3 and securing it. Figure 1 As shown, when the wearer loosens the shoelace 3, they pull the lever 11, causing the lever 11 to separate the ratchet 5 from the pawl 9. At this point, the shoelace 3 is fully loosened, allowing the wearer to remove their foot from the shoe. Figure 2 As shown, this not only extends the lifespan of the shoe buckle 1, but also allows users to maintain a good wearing experience without frequently adjusting the shoelaces 3.

[0030] In Example 2, unlike Example 1, the shoelaces 3 are self-locking via the isolation cover 6, torsion spring 7, and pivot 2, ensuring a proper fit and providing stable support for the foot. Figures 3-4 As shown: A shoelace 3 is slidably connected to the surface of the pivot 2, and the shoelace 3 is slidably set inside the shoe buckle 1. A pull ring 4 is fixedly connected to the surface of the shoelace 3. An isolation cover 6 is fixedly connected to the right side of the shoe buckle 1. One end of a torsion spring 7 is fixedly connected to the inner wall of the isolation cover 6. The other end of the torsion spring 7 is fixedly connected to the pivot 2. One end of a No. 1 spring 21 is fixedly connected to the upper surface of the pawl 9. The other end of the No. 1 spring 21 is fixedly connected to the shoe buckle 1.

[0031] When the user adjusts the shoelace 3, they pull the loop 4 on the surface of the shoelace 3. The loop 4 then moves the shoelace 3, as shown in the image. Figure 3 As shown, this causes the pivot 2 to rotate inside the shoe buckle 1, and the ratchet 5 on the surface of the pivot 2 to rotate inside the shoe buckle 1. At the same time, the torsion spring 7 on the inner wall of the isolation cover 6 retracts towards the surface of the pivot 2, as shown. Figure 4 As shown, as the ratchet 5 rotates, the pawl 9 swings on the drive shaft 8, thereby adjusting the shoelace 3. When the user releases the pull ring 4, the torsion spring 7 drives the shaft 2 to reverse, at which point the pawl 9 and the ratchet 5 engage. Figure 2 As shown, the self-locking of shoelace 3 can effectively avoid the risk of tripping due to loose shoelace 3, ensuring the safety of the wearer, and improving the convenience of use.

[0032] In Example 3, unlike Example 2, the sliding post 14, buffer spring 16, and force plate 15 ensure that the user can adjust and fix the shoelaces 3, effectively preventing slippage. Figures 5-7 As shown: A sliding column 14 is slidably connected inside the pull rod 11, and a force plate 15 is fixedly connected to the upper surface of the sliding column 14. A limit block 13 is fixedly connected to the inner wall of the pull rod 11. The surface of the limit block 13 is arc-shaped. One end of a buffer spring 16 is fixedly connected to the lower surface of the force plate 15, and the other end of the buffer spring 16 is fixedly connected to the pull rod 11. One end of a sliding rod 17 is slidably connected to the surface of the sliding column 14, and a locking block 18 is fixedly connected to the other end of the sliding rod 17. A limit strip 19 is fixedly connected to the surface of the locking block 18. A limit groove 20 is opened inside the pull rod 11, and the limit strip 19 is slidably connected to the surface of the limit groove 20.

[0033] When the user adjusts the tightness of the shoelaces 3, the user pulls the lever 11, causing the lever 11 to drive the connecting rod 10 to slide inside the shoe buckle 1. This causes the pawl 9 on the surface of the connecting rod 10 to slide on the surface of the drive shaft 8, and causes the first spring 21 to retract towards the inner wall of the shoe buckle 1, thus separating the pawl 9 from the ratchet 5. Figure 5As shown, when the user pulls the lever 11, the force plate 15 causes the sliding column 14 to slide inside the lever 11, and the buffer spring 16 at the lower end of the force plate 15 retracts towards the inner wall of the lever 11, as... Figure 6 As shown, when the sliding column 14 slides, the sliding rod 17 on the surface contacts the limiting block 13. The sliding rod 17 pushes the locking block 18 to slide on the surface of the sliding groove 12, thereby causing the locking block 18 to extend, as shown. Figure 7 As shown, locking the lever 11 allows the adjustment of the shoelace 3 length to be completed instantly, greatly saving time and improving ease of use. At the same time, it can effectively prevent the locking block 18 from coming loose due to accidental touch or vibration during use, providing users with a reliable wearing experience.
