Description

Technical Field

[0001] This utility model relates to the field of shoe accessories technology, and in particular to an anti-slip easy-tie shoelace buckle and a shoe with an anti-slip easy-tie shoelace buckle. Background Technology

[0002] Traditional footwear products generally use shoelaces as a fastening component, adjusting the fit of the shoe upper through knotting. However, existing shoelace systems suffer from the following technical bottlenecks:

[0003] 1) The contradiction between ease of operation and reliability is prominent.

[0004] Traditional shoelaces rely on complex looping and knotting for fastening. For children, the elderly, or users in sports scenarios, the knotting process is time-consuming and prone to errors. At the same time, the vibration of sports or long-term use can cause the knots to loosen, resulting in the risk of the shoelaces coming loose, which affects the safety of wearing and the user experience.

[0005] 2) Insufficient precision in comfort adjustment

[0006] Current shoelaces adjust tightness only by manually pulling on the knot, lacking a standardized constraint structure and making it difficult to precisely control the upper's support. This leads to localized pressure or excessive looseness on the instep, especially during prolonged walking or exercise, where comfort issues become more pronounced.

[0007] 3) Limitations in structural design and scene adaptability

[0008] Traditional shoelaces often have their ends exposed vertically, lacking an effective restraint structure. Horizontal or diagonal external forces can easily act directly on the knot, causing it to loosen. In addition, traditional shoelace buckles are not compatible with shoelace lengths and materials (such as flat straps, round straps, cotton / nylon straps), making it difficult to meet the design needs of diverse footwear such as athletic shoes, casual shoes, and children's shoes.

[0009] In existing technologies, some shoelace buckles improve the above-mentioned problems by simplifying the perforation structure. For example, CN202233364U discloses a no-tie shoelace buckle. When it is necessary to tighten the shoelaces, shoelaces 13 and 14 are threaded through the threading holes 2 and 3 respectively, and then the rotated shoelaces 11 and 12 are threaded through the locking holes 4 and 5 respectively. Then, the ends of shoelaces 11 and 12 are grasped and pulled tight, so that the threading holes and locking holes lock the shoelaces, achieving the function of tightening the shoelaces without tying them. When it is necessary to loosen the shoelaces, simply grasp the ends of shoelaces 11 and 12 and lift them, so that shoelaces 11 and 12 are pulled out from the shoelace pull-out notches 6 and 7 respectively, and the shoelaces will loosen. Since the shoelace pull-out notches in this utility model are set in the perpendicular direction of the plane formed by the shoelaces that have passed through the threading holes and the shoelaces that have rotated and passed through the locking holes, the shoelaces will not loosen during normal walking. The shoelaces will only untie themselves from the locking eyelets when subjected to a force in the same direction as the pull-out notch, thus loosening the shoelaces. While this system allows for quick tension adjustment through the interlocking of the threading and locking eyelets, its anti-slip mechanism still relies on single-point friction constraints, lacking a multi-level, multi-directional mechanical constraint structure. In complex sports scenarios, such as running and multi-angle ankle movements, lateral or diagonal pulling forces can easily exceed the single friction threshold, leading to shoelace loosening and failure. Furthermore, existing solutions lack biomimetic design for shoelace shape, making it difficult to balance functionality and personalized aesthetic needs.

[0010] Therefore, there is an urgent need for a new type of shoelace buckle that combines convenient fastening, multi-directional anti-slip, precise adjustment, and shape adaptation to solve the core pain points of traditional shoelaces, such as "difficult to fasten, easy to slip off, and rough adjustment," while improving wearing comfort, scene applicability, and product added value. Utility Model Content

[0011] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an anti-slip easy-tie shoelace buckle and a shoe with an anti-slip easy-tie shoelace buckle.

[0012] The above-mentioned objective of this utility model is achieved through the following technical means:

[0013] An easy-to-fasten, anti-slip shoelace buckle includes a buckle body 1 for fastening shoelaces 8, wherein the shoelaces 8 have a strap end 82 for easy threading through holes.

[0014] The buckle body 1 has a lower common hole 2 and an upper common hole 3, a first shoelace hole 4 and a second shoelace hole 5 arranged adjacent to the lower common hole 2, and a third shoelace hole 6 and a fourth shoelace hole 7 arranged adjacent to the upper common hole 3;

[0015] The shoelace 8 has a rough texture, and the strap 81 of the shoelace 8 is adapted to the first shoelace eye 4, the second shoelace eye 5, the third shoelace eye 6 and the fourth shoelace eye 7 with the same diameter;

[0016] Both the upper common hole 3 and the lower common hole 2 can accommodate two belts 81 that are inserted into them.

[0017] Optionally, the upper hole 3, the third shoelace hole 6, and the fourth shoelace hole 7 are arranged in a straight line.

[0018] Preferably, the upper hole 3 is located below the third shoelace hole 6 and the fourth shoelace hole 7, and the three form an inverted triangle line.

[0019] Optionally, both the lower common hole 2 and the upper common hole 3 have rectangular holes.

[0020] Optionally, both the lower common hole 2 and the upper common hole 3 have elliptical holes.

[0021] Preferably, the holes of both the lower common hole 2 and the upper common hole 3 are elliptical in shape.

[0022] Preferably, the lower common hole 2, the first shoelace hole 4, and the second shoelace hole 5 are arranged in a straight line, and a shoelace groove 11 is opened below them.

[0023] Preferably, the buckle body 1 further extends an information plate 12, and the information plate 12 is staggered with the buckle body 1.

[0024] Preferably, the information board 12 has a logo.

[0025] This utility model also discloses a shoe with an anti-slip easy-tie shoelace buckle, including a shoe with shoelaces 8 attached, the shoelaces 8 being attached to the anti-slip easy-tie shoelace buckle.

[0026] The beneficial effects of adopting the above technical solution are as follows:

[0027] 1) This anti-slip and easy-tie shoelace buckle has achieved a breakthrough in convenience, stability, adjustability and applicability, effectively solving the pain points of traditional shoelaces that are easy to loosen, difficult to adjust and have a single shape. It has significant practical value and market application potential.

[0028] 2) The top three eyelets (3), third eyelet (6), and fourth eyelet (7) are arranged in a straight line, with the tail section (butterfly tail) extending laterally. After being bent laterally, the tail section fits snugly against the upper. It overcomes lateral friction and upper pressure during non-vertical pulling, enhancing its resistance to loosening in the horizontal direction. This makes it suitable for high-frequency lateral movements (such as brisk walking and lateral movement). The straight layout ensures that the tension in the tail section is evenly distributed horizontally, reducing wear on one side of the laces and improving structural durability.

[0029] 3) The third eyelet is located below the third and fourth eyelets, forming an inverted triangle. The tail (butterfly tail) extends diagonally. The diagonal bend of the tail more closely resembles the shape of a real butterfly tail, enhancing the aesthetics of the biomimetic design while achieving the anti-slip function and meeting personalized decoration needs. The diagonal bend structure can effectively cope with diagonal pulling forces (such as the pulling force when the ankle joint rotates), broadening the adaptability of the anti-slip mechanism to the force direction and improving stability in complex sports scenarios.

[0030] 4) The lower common hole 2 and the upper common hole 3 are rectangular, with the long side aligned with the lace threading path. The straight edges of the rectangular holes form a flat surface with the rough texture of the laces, increasing the friction contact area, improving the clamping stability of the laces within the common holes, and enhancing the anti-slip effect; the long side guides the laces to thread in a straight line, reducing skew or jamming during threading, and combined with the perforation design of the lace tip 82, further improving fastening efficiency.

[0031] 5) The lower common hole 2 and the upper common hole 3 are elliptical, with their major axes adapted to the width direction of the shoelace body 81. The curved edges of the elliptical holes reduce the friction of sharp corners when the shoelaces are worn, making them especially suitable for high-frequency adjustment scenarios, such as real-time adjustment of tightness during exercise, reducing wear on the shoelace surface; the curved structure disperses the pressure on the hole walls of the shoelace, avoiding breakage of the shoelace body due to local stress concentration, and extending the service life of the shoelaces.

[0032] 6) The lower common hole 2 and the upper common hole 3 are nearly rectangular, but the corners are rounded, and the longer side is slightly longer than the shorter side, forming a "rounded rectangle"-like ellipse. This retains the long side of the rectangle for planar contact to maintain a certain level of friction, while the rounded corners reduce chafing of the shoelaces, balancing stability and ease of wear, making it suitable for everyday use. The transitional shape can accommodate shoelaces of different materials such as cotton and nylon, avoiding the cutting damage to soft shoelaces caused by right-angle holes, and providing more stable clamping for flat shoelaces than standard elliptical holes. The rounded corners enhance the structural strength of the hole walls, reducing deformation of the hole openings due to repeated pulling during long-term use, and extending the lifespan of the shoelace buckles.

[0033] 7) The shoelace groove 11 is a groove structure below the lower common hole 2 and the first / second shoelace hole. The front sections of the free ends of the left and right shoelaces are stretched laterally and then embedded in the groove to form a three-layer clamping structure of "buckle body - shoelace groove - shoe upper". Compared to a grooveless design, the front section of the shoelace is actively pressed into the groove instead of hanging naturally, significantly increasing the contact friction area between the shoelace and the buckle. Especially when pulled laterally or diagonally, the groove wall can directly block the shoelace displacement, further improving the anti-slip performance. After the front section of the shoelace is fixed in the shoelace groove 11, it can prevent the free end from shaking or shifting due to the vibration of the shoe upper during walking, keeping the shoelace buckle and the shoe upper in a tight and close fit, reducing the local pressure of the shoelace on the instep, and improving wearing comfort and long-term stability. When threading the shoelace, the guiding function of the shoelace groove 11 helps the user quickly locate the pressing position of the front section of the shoelace. Combined with the threading logic of Example 1, a standardized operation process of "threading-pressing-stretching" is formed, which is especially suitable for scenarios that require frequent adjustment of tightness, reducing the time and difficulty of repeated putting on and taking off.

[0034] 8) The information board 12 and the buckle 1 are staggered, providing additional flat space without affecting the shoelace threading and the core anti-slip and adjustment functions of the buckle. This space can be used to carry logos, parameter information or decorative elements, enhancing the product's practicality and personalization possibilities.

[0035] 9) By setting the logo on the information board 12, the brand recognition of the product is directly improved, which facilitates user identification and marketing. It is especially suitable for use with branded footwear products. The logo is integrated into the functional buckle as a decorative element, which not only achieves technical effects such as anti-slip and easy fastening, but also meets consumers' needs for the aesthetics and personalization of footwear accessories, thereby enhancing product competitiveness.

[0036] 10) This shoe features anti-slip and easy-tie shoelace buckles. Through systematic innovation in shoelace buckles, it solves the pain points of traditional shoelaces, such as "easy to loosen, difficult to adjust, and monotonous in shape". It combines convenience, stability, comfort and personalization to significantly improve the overall user experience of the shoe. Attached Figure Description

Detailed Implementation

[0045] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] 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 a part of the embodiments of the present utility model, and not all of them. 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.

[0047] Example 1. This example illustrates an easy-to-tie shoelace buckle that prevents slippage, such as... Figure 1-6 As shown, it includes a buckle body 1 for fastening shoelaces 8, the shoelaces 8 having a strap end 82 for easy threading through holes.

[0048] The buckle body 1 has a lower common hole 2 and an upper common hole 3, a first shoelace hole 4 and a second shoelace hole 5 arranged adjacent to the lower common hole 2, and a third shoelace hole 6 and a fourth shoelace hole 7 arranged adjacent to the upper common hole 3;

[0049] The shoelace 8 has a rough texture, and the strap 81 of the shoelace 8 is adapted to the first shoelace eye 4, the second shoelace eye 5, the third shoelace eye 6 and the fourth shoelace eye 7 with the same diameter;

[0050] Both the upper common hole 3 and the lower common hole 2 can accommodate two belts 81 that are inserted into them.

[0051] The following is an example of how to fasten shoelaces. The shoelaces are pre-secured through symmetrical eyelets on both sides of the front of the shoe, above the tongue. Then, the laces extend from two eyelets near the shoe opening, one on the left and one on the right, creating free ends for the left and right shoelaces. The example of fastening is as follows:

[0052] Example 1 of tying a bow:

[0053] like Figure 6-7 As shown, the free end of the left shoelace passes through the end piece 82, which facilitates threading, and then through the common hole 2 and the first shoelace hole 4. After leaving a middle section of length, the free end of the left shoelace passes through the common hole 3 and the third shoelace hole 6.

[0054] The free end of the right shoelace passes through the eyelet 82, which facilitates threading, and then through the second shoelace eyelet 5. After leaving a middle section of the free end of the right shoelace, it passes through the second shoelace eyelet 3 and the fourth shoelace eyelet 7.

[0055] Adjust and stretch the free ends of the left and right shoelaces until the first shoelace eyelet 4, the second shoelace eyelet 5 and the lower common eyelet 2 mutually constrain the shoelaces to provide a moderate fit to the shoe, forming the first constrained segment 811 that splits into the first shoelace eyelet 4 from the lower common eyelet 2 and the second constrained segment 812 that splits into the second shoelace eyelet 5; the front sections of the free ends of the left and right shoelaces form butterfly antennae that are restrained in a figure-eight shape under the constraint of the two shoelace eyelets that are one on the left and one on the right near the shoe opening;

[0056] After leaving the middle section of the free ends of the left and right shoelaces, thread them through the three holes.

[0057] Adjust and stretch the free ends of the left and right shoelaces until the third shoelace eyelet 6, the fourth shoelace eyelet 7 and the upper common eyelet 3 tightly bind the shoelaces together, forming the third constraint segment 813 that enters the third shoelace eyelet 6 from the upper common eyelet 3 and the fourth constraint segment 814 that enters the fourth shoelace eyelet 7; the reserved middle length of the free ends of the left and right shoelaces forms like the wings of a butterfly, and the free ends of the left and right shoelaces extend out of the third / fourth shoelace eyelet and naturally stretch out to form like the tail of a flowing butterfly.

[0058] To adjust the tightness of the laces: pull up the first constraint section 811 and the second constraint section 812 by a certain distance, pull down the front section of the free end of the left and right shoelaces to loosen them, and pull down the part of the free end of the left and right shoelaces after passing through the first shoelace eyelet 4 and the second shoelace eyelet 5 to tighten them.

[0059] To adjust the length of the middle and tail sections: pull up the third constraint section 813 and the fourth constraint section 814 by a certain distance, pull down the free ends of the left and right shoelaces to adjust the length of the tail section extending out of the shoelace buckle (butterfly tail length), and pull down the free ends of the left and right shoelaces after passing through the third shoelace eyelet 6 and the fourth shoelace eyelet 7 to adjust the length of the middle section (butterfly wing size, butterfly tail length).

[0060] Easy to tie: The entire tying process is done through holes, making it very easy to adjust the tightness and the "butterfly" shape.

[0061] Anti-slip: After putting on the shoes, the instep causes the shoe upper to bulge and expand, pulling back the left and right shoelaces, which are already restrained by the free ends of buckle body 1, making the shoelace buckle fit tightly against the shoe upper. The free ends of the left and right shoelaces located below buckle body 1 are pressed between the shoelace buckle and the shoe. The parts of the free ends of the left and right shoelaces that extend from between the shoelace buckle and the shoe (such as butterfly antennae, butterfly wings, and butterfly tails) are partially pressed and bent out of the shoelace buckle. The non-vertical (after bending and extending, they are horizontal or diagonal) pulling of the bent and extended parts cannot change the restraining force of the shoelace buckle on the shoelaces, preventing the shoelaces from loosening and falling off.

[0062] Example 2 of tying a bow:

[0063] The only difference between this example and Example 1 of the bow knot is the order of the holes and the timing of the adjustment and stretching; the rest is the same.

[0064] The free ends of the left and right shoelaces pass through the eyelet 82, which facilitates threading, and are threaded through the common eyelet 2.

[0065] The free end of the left shoelace passes through the first shoelace eyelet 4, and the free end of the right shoelace passes through the second shoelace eyelet 5. The free ends of the left and right shoelaces are adjusted and stretched until the first shoelace eyelet 4, the second shoelace eyelet 5 and the lower common eyelet 2 mutually constrain each other, so that the shoelaces provide a moderate fit to the shoe. This forms a first constrained segment 811 that enters the first shoelace eyelet 4 from the lower common eyelet 2 and a second constrained segment 812 that enters the second shoelace eyelet 5. The front sections of the free ends of the left and right shoelaces form a butterfly antennae that are restrained and shaped like a figure eight under the constraint of the two shoelace eyelets that are one on the left and one on the right near the shoe opening.

[0066] After leaving the middle section of the free ends of the left and right shoelaces, thread them through the three holes.

[0067] The free end of the left shoelace is threaded through the third shoelace eyelet 6, and the free end of the right shoelace is threaded through the fourth shoelace eyelet 7. The free ends of the left and right shoelaces are adjusted and stretched until the third shoelace eyelet 6, the fourth shoelace eyelet 7 and the upper common eyelet 3 tightly bind the shoelaces together, forming the third constraint segment 813 that enters the third shoelace eyelet 6 from the upper common eyelet 3 and the fourth constraint segment 814 that enters the fourth shoelace eyelet 7. The reserved middle length of the free ends of the left and right shoelaces forms like the wings of a butterfly, and the free ends of the left and right shoelaces extend out of the third / fourth shoelace eyelet and naturally stretch out to form a flowing butterfly tail.

[0068] Example 3 of tying a bow:

[0069] The only difference between this example and Example 1 (the example of a bow tie) is the order of the holes; otherwise, the principle is the same.

[0070] The free ends of the left and right shoelaces are threaded through the eyelets 82, which facilitate the threading of the eyelets, and then threaded through the first shoelace eyelet 4 and the second shoelace eyelet 5, respectively.

[0071] After leaving the middle section of the free ends of the left and right shoelaces, thread them through the three holes.

[0072] The free ends of the left and right shoelaces are threaded through the third shoelace eyelet 6 and the fourth shoelace eyelet 7, respectively.

[0073] This example can also form the first constraint segment 811, the second constraint segment 812, the third constraint segment 813, and the fourth constraint segment 814, as well as form butterfly antennae, butterfly wings, and butterfly tail; it can also adjust the tightness and adjust the "butterfly" shape; it can also achieve easy fastening and prevent slippage.

[0074] Example 4 of tying short shoelaces:

[0075] This example illustrates how to fasten shoelaces with shorter free ends on the left and right sides. The process of threading the laces is similar to the example of knotting a bow in Examples 1-3. The difference is that there is no need to reserve the middle section length; only the tail section of the free end of the left and right shoelaces extends out of the shoelace at the very end.

[0076] This example can also form the first constraint segment 811, the second constraint segment 812, the third constraint segment 813, and the fourth constraint segment 814, and can also form butterfly antennae and butterfly tail, can also adjust the tightness, and can also achieve easy binding and anti-slip.

[0077] The anti-slip-off and easy-to-tie shoelace buckle provided by this utility model achieves multiple technical effects such as easy fastening, anti-slip-off, flexible adjustment, and aesthetic appearance through a unique buckle structure design and shoelace perforation method, as detailed below:

[0078] 1) Convenient and easy to fasten, reducing operational difficulty. The lower common hole 2, upper common hole 3, and the first to fourth shoelace holes on the buckle body 1 create a standardized perforation path. All fastening processes can be completed simply by threading the strap end 82 through the corresponding hole, eliminating the need for the complex looping or weaving actions of traditional knotting, significantly lowering the user's operational threshold. Whether it is a regular length shoelace with a bow-knot fastening as shown in examples 1-2, or a short shoelace scenario as shown in example 3, the unified perforation logic can quickly complete the fastening, truly achieving "put on and fasten immediately, fasten securely immediately," which is especially suitable for the quick dressing needs of children, the elderly, or sports scenarios.

[0079] 2) Multiple constraint structure to enhance anti-detachment performance.

[0080] Dynamic, tight fit and synergy: When the shoes are worn, the expansion force generated by the instep supporting the upper pulls back the free end of the shoelaces, making the buckle 1 fit tightly against the upper. At this time, the free end of the shoelaces located below the buckle is pressed between the buckle and the upper, forming a horizontal or diagonal "butterfly tendril" shape, rather than the traditional vertical extension. This bending structure means that external pulling force must first overcome the friction and pressure of the upper at the bend, and non-vertical pulling cannot be directly transmitted to the restrained section, thus physically inhibiting the shoelaces from loosening.

[0081] Four-segment constraint coordination: The shoelace is constrained at four points across two layers by the first constraint segment 811 and the second constraint segment 812 formed by the lower common hole 2 and the first / second shoelace hole, and the third constraint segment 813 and the fourth constraint segment 814 formed by the upper common hole 3 and the third / fourth shoelace hole 6. Each constraint segment is adapted to the hole diameter and the strap body 81, and the rough texture of the strap body increases friction to achieve stable winding. The superposition of multiple constraints significantly improves the locking ability of the shoelace buckle on the shoelace, preventing natural loosening due to sports vibration or long-term use.

[0082] 3) The system can be flexibly adjusted to adapt to diverse needs.

[0083] Stepless tightness adjustment: By pulling up the first / second constraint section, the part of the shoelace that is not inserted into the buckle can be adjusted to achieve linear adjustment of the tightness of the shoe. Pulling down the part of the free end that passes through the first / second shoelace eyelet will tighten the upper, and vice versa. The operation is clear and the feedback is intuitive, meeting the personalized needs of different foot shapes for fit.

[0084] Customizable Shape Function: The combination of the three upper eyelets and the third / fourth shoelace eyelet allows users to freely control the size and shape of the "butterfly" shape by adjusting the reserved lengths of the middle section (butterfly wings) and the tail section (butterfly tail). Pulling up the third / fourth restraint section and pulling down the tail section can extend the length of the butterfly tail, while pulling down the middle section can increase the spread of the wings, balancing functionality and decoration to meet the appearance needs of various scenarios such as casual, sports, and fashion.

[0085] Shoelace length compatibility: Whether it's regular-length shoelaces that support tying a complete butterfly shape or short shoelaces, the buckle can be completed by omitting the middle section, breaking through the strict limitations of traditional shoelace buckles on shoelace length and expanding the product's applicability.

[0086] 4) Optimized structural design to enhance user experience.

[0087] Dual common hole threading structure: Both the lower common hole 2 and the upper common hole 3 support the simultaneous threading of two straps 81, forming a symmetrical threading path of "double in and double out", ensuring that the shoelaces are evenly stressed and avoiding deformation or local wear of the shoe upper caused by excessive tension on one side.

[0088] Rough texture anti-slip: The surface of the shoelace 81 is provided with a rough texture. When it is matched with the shoelace hole with the same diameter, it can increase the contact friction and prevent the shoelace from sliding in the hole, further enhancing the fixing effect of the restraint section.

[0089] Bionic form design: By simulating the form of tentacles (front section of the free end), wings (middle section), and tail (tail end), the product is made aesthetically pleasing while realizing its function, enhancing users' emotional identification with the product, which is especially in line with the fun design needs of children's shoes and clothing.

[0090] In conclusion, this anti-slip easy-tie shoelace buckle has achieved breakthroughs in convenience, stability, adjustability, and applicability, effectively solving the pain points of traditional shoelaces that are easy to loosen, difficult to adjust, and have a monotonous design. It has significant practical value and market application potential.

[0091] Example 2. This example illustrates the differences in user experience between the layouts of the top common eyelet, the third shoelace eyelet, and the fourth shoelace eyelet 7. Figure 5 As shown, the upper hole 3, the third shoelace hole 6, and the fourth shoelace hole 7 are arranged in a straight line.

[0092] In this embodiment, when fastening shoelaces, the tail section (butterfly tail) of the bow-tie examples 1-3 extends laterally beyond the shoelace buckle. In this embodiment, the upper hole 3, the third shoelace hole 6, and the fourth shoelace hole 7 are arranged in a straight line, with the tail section (butterfly tail) extending laterally. After being bent laterally, the tail section is pressed against the upper, and the non-vertical pulling needs to overcome the lateral friction and pressure of the upper, thus strengthening the horizontal anti-loosening ability, making it suitable for high-frequency lateral movement scenarios (such as brisk walking and lateral movement); the straight layout ensures that the tension of the tail section is evenly distributed in the horizontal direction, reducing unilateral wear of the shoelaces and improving structural durability.

[0093] Example 3. This example illustrates another difference in user experience between the layouts of the top common eyelet, the third shoelace eyelet, and the fourth shoelace eyelet 7. Figure 2 , Figure 6 As shown, the upper hole 3 is located below the third shoelace hole 6 and the fourth shoelace hole 7, and the three form an inverted triangle line.

[0094] In this embodiment, when fastening shoelaces, the tail section (butterfly tail) of the bow-tie examples 1-3 extends diagonally out of the shoelace buckle. In this embodiment, the upper hole 3 is located below the third and fourth shoelace holes, forming an inverted triangle, with the tail section (butterfly tail) extending diagonally. The diagonal bend of the tail section more closely resembles the shape of a real butterfly tail, enhancing the aesthetics of the biomimetic design while achieving the anti-slip function and meeting personalized decoration needs; the diagonal bend structure can effectively cope with diagonal pulling forces (such as the pulling force when the ankle joint rotates), broadening the adaptability of the force direction of the anti-slip mechanism and improving stability in complex sports scenarios.

[0095] Example 4. This example is the first hole shape example of lower common hole and upper common hole, not shown in the figure. The holes of both lower common hole 2 and upper common hole 3 are rectangular.

[0096] In this embodiment, the lower common hole 2 and the upper common hole 3 are rectangular, with their long sides aligned with the path through which the shoelaces are threaded. The straight edges of the rectangular holes form a planar fit with the rough texture of the shoelaces, increasing the frictional contact area, improving the clamping stability of the shoelaces within the common holes, and enhancing the anti-slip effect. The long side guides the shoelaces to thread in a straight line, reducing skew or jamming during threading. Combined with the perforation design of the strap end 82, this further improves the efficiency of fastening.

[0097] Example 5. This example is the second hole shape example of lower and upper common holes, not shown in the figure. The holes of both lower common hole 2 and upper common hole 3 are elliptical.

[0098] In this embodiment, the lower common hole 2 and the upper common hole 3 are elliptical, with their major axes adapted to the width direction of the shoelace body 81. The curved edges of the elliptical holes reduce the friction of sharp corners when the shoelaces are worn, making them particularly suitable for high-frequency adjustment scenarios, such as real-time adjustment of tightness during exercise, thus reducing wear on the shoelace surface. The curved structure disperses the pressure on the hole walls of the shoelace, avoiding breakage of the shoelace body due to local stress concentration, and extending the service life of the shoelaces.

[0099] Example 6. This example is the third example of a hole shape with both lower and upper common holes, such as... Figure 1-3 As shown in Figures 6-7, the holes of both the lower common hole 2 and the upper common hole 3 are elliptical in shape.

[0100] In this embodiment, the lower common hole 2 and the upper common hole 3 are nearly rectangular, but the corners are rounded, and the longer side is slightly longer than the shorter side, forming a rounded rectangle-like ellipse. The long side of the rectangle is kept in planar contact to maintain a certain level of friction, while the rounded corners reduce the chafing of the shoelaces, balancing stability and ease of wear, making it suitable for everyday use. The transitional shape can accommodate shoelaces of different materials such as cotton and nylon, avoiding the cutting damage to soft shoelaces caused by right-angle holes, and providing more stable clamping for flat shoelaces than standard elliptical holes. The rounded corners enhance the structural strength of the hole walls, reducing deformation of the hole openings due to repeated pulling during long-term use, and extending the lifespan of the shoelace buckles.

[0101] Example 7. This example is a shoelace groove, such as... Figure 1-4 As shown, the lower common hole 2, the first shoelace hole 4, and the second shoelace hole 5 are arranged in a straight line, and shoelace grooves 11 are opened below them.

[0102] In use, please refer to Example 1. After the front ends of the left and right shoelaces extending from the shoelace buckle are stretched laterally, their front ends are pressed under the shoelace groove 11 of the shoelace buckle. The shoelace groove 11 is a groove structure below the lower common hole 2 and the first / second shoelace hole. After the front ends of the left and right shoelaces are stretched laterally, they are embedded in the groove, forming a three-layer clamping structure of "buckle body - shoelace groove - shoe upper". Compared to a grooveless design, the front section of the shoelace is actively pressed into the groove instead of hanging naturally, significantly increasing the contact friction area between the shoelace and the buckle. Especially when pulled laterally or diagonally, the groove wall can directly block the shoelace displacement, further improving the anti-slip performance. After the front section of the shoelace is fixed in the shoelace groove 11, it can prevent the free end from shaking or shifting due to the vibration of the shoe upper during walking, keeping the shoelace buckle and the shoe upper in a tight and close fit, reducing the local pressure of the shoelace on the instep, and improving wearing comfort and long-term stability. When threading the shoelace, the guiding function of the shoelace groove 11 helps the user quickly locate the pressing position of the front section of the shoelace. Combined with the threading logic of Example 1, a standardized operation process of "threading-pressing-stretching" is formed, which is especially suitable for scenarios that require frequent adjustment of tightness, reducing the time and difficulty of repeated putting on and taking off.

[0103] Example 8. This example shows an information board, such as... Figure 1-4 As shown, the buckle body 1 also extends an information plate 12, which is staggered with the buckle body 1.

[0104] In this embodiment, the information board 12 and the buckle 1 are staggered, providing additional planar space without affecting the shoelace threading and the buckle's core anti-slip and adjustment functions. This space can be used to carry logos, parameter information, or decorative elements, enhancing the product's practicality and personalization possibilities.

[0105] Example 9. This example shows the information board displaying a logo, such as... Figure 1-2 As shown, the information board 12 has a logo.

[0106] In this embodiment, by setting a logo on the information board 12, the brand recognition of the product is directly improved, which facilitates user identification and market promotion. It is especially suitable for use with branded footwear products. The logo is integrated into the functional buckle as a decorative element, which not only achieves technical effects such as anti-slip and easy fastening, but also meets consumers' needs for the aesthetics and personalization of footwear accessories, thereby enhancing product competitiveness.

[0107] Example 10. This example illustrates a shoe with an easy-to-tie, anti-slip shoelace buckle, such as... Figure 1-7 As shown, the shoe includes a shoe with shoelaces 8 attached to an easy-tie buckle.

[0108] This embodiment inherits the standardized perforation and fastening logic of Embodiment 1, and combines it with the lateral pressing structure of the shoelace groove in Embodiment 7 to achieve immediate fastening and secure fastening, significantly improving wearing efficiency. Simultaneously, through multi-layered constraint sections such as the first to fourth constraint sections and a non-vertical bending design, it effectively prevents shoelaces from loosening during exercise or long-term use. Relying on the stepless tightness adjustment mechanism of Embodiment 1 and the compatibility of different hole shapes with shoelace materials and thicknesses in Embodiments 4-6, it meets the comfortable wearing needs of different foot shapes and usage scenarios, reducing pressure on the instep. The optimized hole layout of Embodiments 2-3 ensures uniform force distribution, and combined with the rounded transition edge design of the elliptical holes in Embodiment 6, it reduces wear between the shoelaces and the hole walls, extending the lifespan of the shoelaces and buckles, especially suitable for high-frequency use scenarios. The staggered information panel placement and logo display function in Embodiments 8-9, without affecting core performance, endows the shoes with decorative appeal and brand recognition, achieving an organic combination of functional accessories and footwear appearance design, enhancing product added value.

[0109] Example 10 solves the pain points of traditional shoelaces, such as "easy to loosen, difficult to adjust, and monotonous in shape", through systematic innovation of shoelace buckles. It combines convenience, stability, comfort and personalization to significantly improve the overall user experience of the shoes.

Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
