Description

Technical Field

[0001] This utility model relates to the field of shoe buckle technology, specifically to an integrated molded anti-breakage shoe buckle device. Background Technology

[0002] Traditional lace-up shoes typically use bows to secure the laces. However, during daily activities, especially sports or children running and jumping, the bows can easily loosen or come undone due to stress or friction, causing the laces to drag on the ground and posing safety hazards such as tripping and trampling. To address this issue, shoelace buckles or locks have appeared on the market. However, existing products often have the following shortcomings: 1. Complex structure, inconvenient to install and remove; 2. Poor versatility, requiring the shoelaces to be cut or specific shoelaces to be used; 3. Inadequate locking force, easily opened accidentally; or overly tight, making removal difficult; 4. Lack of effective storage and management for excessively long shoelace ends, affecting both aesthetics and safety.

[0003] Therefore, there is an urgent need for a shoe buckle device that is simple in structure, highly versatile, reliable in locking, easy to assemble and disassemble, and can properly handle excess shoelaces. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an integrated molded anti-breakage shoe buckle device. This device can effectively lock the shoelace knot and prevent it from loosening. It also has the advantages of quick installation, convenient disassembly, strong versatility and high safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated anti-breakage shoe buckle device includes an upper buckle and a lower buckle, which are symmetrically distributed vertically and detachably connected by a locking device. The upper and lower buckles have corresponding shoe knot receiving grooves of the same shape and size in the middle for accommodating shoelace knots. Shoelace guide grooves are provided on both sides of the shoe knot receiving groove. One end of each shoelace guide groove communicates with the shoe knot receiving groove, and the other end extends to the outside of the buckle for fixing the free end of the shoelace and the rope loop. At least two positioning posts protrude from the upper surface of the lower buckle, and positioning holes matching the positioning posts are correspondingly provided on the lower surface of the upper buckle. When the upper and lower buckles are fastened, the positioning posts are inserted into the positioning holes for guidance and positioning. The locking device includes at least one set of locking rods detachably passing through the upper and lower buckles for locking the fastened upper and lower buckles.

[0006] Furthermore, the locking device also includes a connecting rope. The upper and lower fasteners have two symmetrically arranged through locking holes. Each locking rod has a limiting part at its upper end. The radial dimension of the limiting part is larger than the radial dimension of the locking rod body and the diameter of the locking hole. The upper end of the upper fastener has a relief groove corresponding to the position of each locking hole. The limiting part is accommodated in the relief groove. The two relief grooves are connected by a groove. The connecting rope is disposed in the groove, and its two ends are respectively connected to the limiting parts of the two locking rods.

[0007] Preferably, a first magnetic attractor is embedded in the bottom of the clearance groove, and a second magnetic attractor is provided on the lower end face of the limiting part to attract and cooperate with the first magnetic attractor.

[0008] Preferably, the groove has retrieval openings on both sides of the center, and the retrieval openings are connected to the groove for inserting fingers or tools to hook the connecting rope.

[0009] Preferably, the bottom of the shoelace guide groove is provided with an elastic pad, and the top surface of the elastic pad is lower than the opening height of the shoelace guide groove.

[0010] Preferably, at least two strap-winding rods are provided around the periphery of the shoe knot receiving groove, and a gap is left between the strap-winding rods and the side wall of the shoe knot receiving groove for the shoelace to be threaded through.

[0011] More preferably, the wrapping rods are evenly distributed circumferentially along the shoe knot receiving groove.

[0012] Furthermore, the upper and lower fasteners are made using a one-piece molding process, resulting in a robust structure that is not easily damaged.

[0013] As described above, the integrated anti-breakage shoe buckle device provided by this utility model has the following beneficial effects: the upper and lower buckles completely enclose the shoelace knot in the shoe knot receiving groove and are firmly fixed by the locking device, effectively preventing the shoelace knot from loosening or unraveling due to external force; the cooperation between the positioning post and the positioning hole makes the buckling quick and accurate; the cooperation design between the locking rod and the magnetic part ensures the firmness of the locking and prevents children from accidentally opening it, and can be easily disassembled by pulling the connecting rope when needed, solving the contradiction of "easy to lose" and "difficult to disassemble"; the design of the connecting rope and the groove avoids the risk of the rope being exposed and hooked; it is suitable for any existing lace-up shoes, without the need for any cutting or replacement of the shoelaces, and the original shoelaces can be used directly; the shoelace guide groove can properly store the shoelace end and rope loop, avoiding dragging and tripping; the elastic padding layer in the groove can buffer the pressure damage to the shoelaces and extend the service life of the shoelaces; the wrapping rod provides a solution for winding and storing the long shoelace end, keeping the shoe surface clean.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-5 As shown, this utility model provides an integrated anti-breakage shoe buckle device: including an upper buckle 1, a lower buckle 2 and a locking device 3. The upper buckle 1 and the lower buckle 2 are preferably made of engineering plastics such as ABS and nylon through an integrated injection molding process to ensure structural strength, and the two are symmetrical in shape.

[0021] Two cylindrical positioning pins 21 are protruding from the upper end face of the lower fastener 2. Two positioning holes 11 are correspondingly opened on the lower end face of the upper fastener 1, which are fitted with the positioning pins 21 with a clearance. When the upper fastener 1 and the lower fastener 2 are aligned and fastened, the positioning pins 21 are accurately inserted into the positioning holes 11, which plays a role in quick guidance and precise positioning, and prevents the two from being misaligned.

[0022] The center positions of the upper buckle 1 and the lower buckle 2 together form a complete shoe knot receiving groove 4, which is used to accommodate the tied shoelace knot. A shoelace guide groove 5 extends from the left and right sides of the shoe knot receiving groove 4. One end of the shoelace guide groove 5 is connected to the shoe knot receiving groove 4, and the other end opens to the side of the buckle. The free ends of the shoelaces on both sides of the shoelace knot and the formed rope loops can pass through the shoelace guide grooves 5 on both sides and be tightened. The bottom of the shoelace guide groove 5 is pasted or embedded with an elastic pad 51 made of rubber material, and its top is slightly lower than the opening of the shoelace guide groove 5, so that the shoelaces can be cushioned when they are tightened to avoid excessive wear.

[0023] Six short, cylindrical strapping rods 7 are evenly distributed along the edge of the shoelace receiving groove 4. There is a gap between the strapping rods 7 and the side wall of the receiving groove 4. When the free end of the shoelace is too long, it can be wrapped around the strapping rods 7 several times before being threaded into the shoelace guide groove 5, which serves to store and organize the laces.

[0024] The locking device 3 is used to finally fix the upper fastener 1 and the lower fastener 2 that have been fastened. Two through locking holes 6 are provided on the upper fastener 1 and the lower fastener 2 respectively. The locking rod 31 is a cylindrical rod with a tapered lower end for insertion. The upper end of the locking rod 31 is provided with an integrally formed disc-shaped limiting part 33. The upper surface of the upper fastener 1 is provided with a circular relief groove 12 corresponding to the position of each locking hole 6. Its diameter is larger than that of the limiting part 33 and its depth is slightly larger than that of the limiting part 33, so that the limiting part 33 can be completely embedded in it without protruding.

[0025] The two clearance slots 12 are connected by a shallow strip groove 13. A soft connecting rope 32 (such as a nylon rope) is tied at both ends to the limiting parts 33 of the two locking rods 31 respectively, and the middle section is placed in the groove 13. A retrieval port 14 is provided in the middle part of the groove 13 to facilitate the use of fingers or crochet hooks to reach into the groove 13 and hook the connecting rope 32.

[0026] To provide a moderate locking force, a small first magnet 34 (first magnetic attractor) is embedded at the bottom of the clearance groove 12, and a corresponding second magnet 35 (second magnetic attractor) is attached to the lower surface of the limiting part 33. When the locking rod 31 is inserted to the bottom, the two magnets attract each other, providing a slight holding force for the locking rod 31 to prevent it from accidentally falling off due to slight vibration or contact. In particular, it can prevent children from easily pulling it out while playing. When disassembly is required, simply pull up the connecting rope 32 through the access port 14 to overcome the magnetic force and pull out both locking rods 31 at the same time, which is easy to operate.

[0027] Brief instructions for use: 1. Tighten the shoelaces as usual and tie a knot.

[0028] 2. Insert the lower buckle 2 from below the shoelace knot so that the shoelace knot is placed in its shoelace receiving groove 4.

[0029] 3. Arrange the loops and free ends of the shoelaces on both sides of the knot. If they are too long, you can first wrap them around the lace-wrapping rod 7.

[0030] 4. Insert the rope loops and free ends on both sides into the left and right shoelace guide grooves 5 of the lower buckle 2 respectively and pull them out.

[0031] 5. Align the positioning hole 11 of the upper fastener 1 with the positioning post 21 of the lower fastener 2, and press down to fasten.

[0032] 6. Insert the two locking rods 31 from above the two locking holes 6 until the limiting part 33 is embedded in the clearance groove 12 and you feel the magnetic attraction positioning. Then straighten the connecting rope 32 and put it into the groove 13.

[0033] 7. When disassembling, use your fingers to hook the connecting rope 32 from the access port 14, and pull it upwards to pull out the two locking rods 31 at the same time. Then separate the upper fastener 1 and the lower fastener 2.

[0034] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
