Description

Technical Field

[0001] This utility model relates to the field of eyelet technology, and in particular to a four-sided rhomboid shoe buckle structure. Background Technology

[0002] Eyelet buckles are small holes or metal rings installed on shoes to allow shoelaces to pass through. They ensure that shoelaces can pass smoothly and securely hold the shoes in place. Eyelet buckles can be simple holes or reinforcing rings made of metal, plastic, or other materials.

[0003] Most existing eyelet buckles use a mechanical pressing method to fix the eyelet buckle to the shoe. When the eyelet buckle is pressed in, the rigidity of the eyelet buckle's edge itself damages the shoe, and this connection method causes irreversible damage to the shoe surface. After the eyelet buckle has been in contact with the shoe surface for a certain period of time, wear occurs at the point where the eyelet buckle is installed, i.e., the intersection of the eyelet buckle edge and the shoe surface. When the force is insufficient to support the force of the eyelet buckle or is slightly affected by external forces, the probability of the eyelet buckle falling off increases significantly. Therefore, further processing and improvement of its structure are required, which increases the number of processes and reduces work efficiency. To address this, the inventor proposes a four-sided rhomboid shoe buckle structure to solve the aforementioned technical problem of improving the traditional mechanical pressing method to reduce wear and lower the probability of the eyelet buckle falling off. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0005] A four-sided rhomboid shoe buckle structure includes a buckle body and a fastening assembly. The fastening assembly includes a connecting plate and a pressure plate. The connecting plate and the pressure plate are separate structures. The surface of the connecting plate is provided with a plurality of connecting rods arranged in a ring on the surface of the connecting plate. The surface of the buckle body is provided with rod grooves that are matched and installed with the connecting rods. The rod grooves are arranged in the same manner as the connecting rods and are non-through structures. A rubber flexible rod is installed at one end of the pressure plate. A buffer spring is connected to the outer surface of the rubber flexible rod. The rubber flexible rod is located inside the buffer spring. One end of the rubber flexible rod abuts against the surface of the pressure plate, and the other end of the rubber flexible rod abuts against the surface of the connecting plate. The surface of the connecting plate is provided with connecting holes that are matched and installed with the rubber flexible rod.

[0006] The surface of the pressure plate is equipped with a clamping assembly, which includes a mounting bracket and a barb. One end of the mounting bracket is equipped with a connecting rubber block, and the surface of the connecting plate is provided with a slot that matches and engages with the connecting rubber block.

[0007] The use of connecting rods arranged in a ring on the surface of the connecting plate helps to evenly distribute pressure and ensure a stable connection between the connecting plate and the buckle. The non-through rod grooves help maintain the overall strength of the buckle and avoid structural weakening caused by excessive drilling. The rubber soft rods and buffer springs provide good elasticity and cushioning, allowing the pressure plate to fit tightly against the connecting plate while reducing wear caused by hard contact between the two. In addition, when external force is applied, the buffer springs can absorb part of the force.

[0008] When installing shoe buckles, install the buckle body, connecting plate and pressure plate respectively. Connect the connecting rod on the surface of the connecting plate to the rod groove on the surface of the buckle body to form an assembly. Install this assembly on the shoe upper. Then install the pressure plate and connecting plate on the other end of the shoe upper. The shoe upper needs to be reserved with corresponding holes to facilitate the installation of the buckle body.

[0009] When the pressure plate and connecting plate are installed, the rubber flexible rod is engaged with the connecting hole. By applying pressure, the connecting rubber block on the surface of the pressure plate is connected with the slot, so that the fabric of the shoe upper is located between the connecting plate and the pressure plate. Then, the barbs on the surface of the mounting bracket are used to hook the fabric of the shoe upper, which plays a hooking role and reduces the probability of the buckle falling off the surface of the shoe upper.

[0010] Furthermore, the barbs are installed at both ends of the mounting bracket, one end of the mounting bracket abuts against the surface of the pressure plate, the slots are arranged in a ring on the surface of the connecting plate, the connecting rubber block and the slots are coaxially arranged, the connecting rubber block is arc-shaped, the slots are concave and have the same shape as the connecting rubber block.

[0011] The reverse hook design ensures that the upper fabric can wrap around the hook, reducing the probability of the buckle accidentally coming loose. The circular arrangement of the slots on the surface of the connecting plate helps to evenly distribute the locking force across the surface of the connecting plate, avoiding localized stress concentration. The coaxial arrangement ensures that the connecting rubber block can be embedded in the slot, improving the locking accuracy and reliability. This arrangement reduces the risk of failure due to misalignment. At the same time, the arc-shaped connecting rubber block combined with the concave slot provides a self-locking effect, reducing the probability of the connecting rubber block falling out of the slot. In addition, the arc-shaped design makes the locking action smoother, improving the user experience.

[0012] Furthermore, the surface of the barb is connected to a hook for securing the upper thread, and there is a gap between the hook and the mounting bracket for winding the upper thread; the design of the hook allows the upper thread to be securely wound between the hook and the mounting bracket, thereby preventing the buckle from loosening or slipping, and ensuring that the buckle maintains the appropriate tightness during wear.

[0013] Furthermore, the surface of the connecting plate is equipped with a locking rod to increase the connection stability between the connecting plate and the buckle body. The buckle body abuts against the locking rod through a locking hole. The locking rod and the connecting plate are coaxially arranged, and the connecting rods are arranged circumferentially with the locking rod as the center point.

[0014] The coaxial design of the clamp rod and the connecting plate ensures the alignment accuracy between them, reduces assembly errors, and enhances overall stability. With the clamp rod as the central support point, the pressure from the buckle body can be evenly distributed, avoiding local stress concentration and thus improving the load-bearing capacity. This structure achieves a uniform force distribution effect. The connecting rods are arranged around the clamp rod, so that when the buckle body is subjected to external forces, the force is evenly distributed to the connecting plate and the buckle body through the connecting rods and the clamp rod, improving the product's durability.

[0015] Furthermore, the surface of the buckle body is provided with several weight-reducing grooves, which are prismatic in shape and extend through the surfaces of both ends of the buckle body. By creating weight-reducing grooves on the buckle body, the amount of material used in the manufacturing process can be reduced, thereby reducing the total weight of the product. The lighter product is easier to carry and wear. For applications such as sports shoes that require long-term wear, reducing weight can reduce foot burden and improve comfort. In addition, by scientifically designing the position and shape of the weight-reducing grooves, the prismatic shape of this structure can achieve the weight reduction goal while ensuring sufficient structural strength. The prismatic design helps to evenly distribute external forces throughout the buckle body structure, avoid local stress concentration, and achieve a stable effect.

[0016] Furthermore, the surface of the buckle body is provided with a plurality of decorative grooves, which are non-through structures and are prismatic in shape;

[0017] The use of prismatic decorative grooves adds unique geometric patterns to shoe buckles, making the product more attractive. This design enhances the product's perceived quality and style, and can be adjusted to meet the aesthetic needs of different consumers. Furthermore, since the decorative grooves are non-through, they reduce the weakening of the overall structural strength of the buckle. Compared to through-type weight-reducing grooves, this design achieves a decorative effect without affecting functionality, reduces stress concentration caused by holes, helps prevent cracks or damage during use, and ensures long-term reliability.

[0018] Furthermore, the surface of the buckle is provided with an anti-slip pad to increase the friction between the buckle and the shoe upper, and the buckle is in the shape of a four-sided rhombus. The anti-slip pad can improve the friction between the edge of the buckle and the shoe upper, ensuring that the buckle reduces the probability of slipping or shifting during use, enhancing the stability of the fixation, and the anti-slip pad can evenly distribute the pressure from the buckle, avoiding local pressure on the shoe upper, thereby improving the comfort of wearing. The rhombus structure helps to evenly distribute the external force in four directions, so that the buckle can better withstand multi-directional tension and reduce the occurrence of deformation or damage.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The use of diamond-shaped decorative grooves can add unique geometric patterns to shoe buckles, making the product more attractive. This design can enhance the product's sense of quality and fashion. The diamond structure also helps to distribute external forces evenly in four directions, allowing the buckle to better withstand multi-directional tension and reducing the occurrence of deformation or damage.

[0021] 2. The use of connecting rods arranged in a ring on the surface of the connecting plate helps to evenly distribute pressure and ensures a stable connection between the connecting plate and the buckle body. The non-through rod grooves help maintain the overall strength of the buckle body and avoid structural weakening caused by excessive drilling. The rubber soft rods and buffer springs provide good elasticity and cushioning effect, allowing the pressure plate to fit tightly against the connecting plate while reducing wear caused by hard contact between the two. In addition, when external force is applied, the rubber soft rods and buffer springs can absorb part of the force.

[0022] 3. When installing the shoe buckle, install the buckle body, connecting plate and pressure plate separately. Connect the connecting rod on the surface of the connecting plate to the rod groove on the surface of the buckle body to form an assembly. Install this assembly on the shoe upper. Then install the pressure plate and connecting plate on the other end of the shoe upper. The shoe upper needs to have corresponding holes reserved for the installation of the buckle body.

[0023] 4. When installing the pressure plate and connecting plate, the rubber flexible rod is engaged with the connecting hole. By applying pressure, the connecting rubber block on the surface of the pressure plate is connected with the slot, so that the fabric of the shoe upper is located between the connecting plate and the pressure plate. Then, the barbs on the surface of the mounting bracket are used to hook the fabric of the shoe upper, which plays a hooking role and reduces the probability of the buckle falling off the surface of the shoe upper.

[0024] 5. The pre-drilled holes in the shoe upper facilitate the installation of the buckle. The plate-like pressing method increases the contact area between the buckle and the shoe upper, improving the irreversible damage to the shoes caused by traditional mechanical pressing methods. At the same time, the locking force of this structure comes from the connection between the rubber block and the slot. The locking force of the buckle itself reduces the friction or pulling between the buckle and the shoe upper, thereby increasing the service life of the product. Attached Figure Description

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] For this embodiment, please refer to Figures 1-8 The specific implementation of the four-sided rhomboid shoe buckle structure includes a buckle body 1 and a fastening assembly. The fastening assembly includes a connecting plate 2 and a pressure plate 3. The connecting plate 2 and the pressure plate 3 are separate structures. The surface of the connecting plate 2 is provided with a plurality of connecting rods 4, which are arranged in a ring on the surface of the connecting plate 2. The surface of the buckle body 1 is provided with a rod groove 5 that is matched and installed with the connecting rods 4. The rod groove 5 is arranged in the same manner as the connecting rods 4, and the rod groove 5 is a non-through structure. One end of the pressure plate 3 is provided with a rubber flexible rod 6. A buffer spring 7 is connected to the outer surface of the rubber flexible rod 6. The rubber flexible rod 6 is located inside the buffer spring 7. One end of the rubber flexible rod 6 abuts against the surface of the pressure plate 3, and the other end of the rubber flexible rod 6 abuts against the surface of the connecting plate 2. The surface of the connecting plate 2 is provided with a connecting hole 8 that is matched and installed with the rubber flexible rod 6.

[0036] The surface of the pressure plate 3 is equipped with a clamping assembly, which includes a mounting bracket 9 and a barb 10. One end of the mounting bracket 9 is equipped with a connecting rubber block 11, and the surface of the connecting plate 2 is provided with a slot 12 that matches and engages with the connecting rubber block 11.

[0037] The connecting rods 4 are arranged in a ring on the surface of the connecting plate 2 to distribute pressure evenly and ensure a stable connection between the connecting plate 2 and the buckle 1. The non-through grooves 5 help maintain the overall strength of the buckle 1 and avoid structural weakening due to excessive drilling. The rubber soft rods 6 and the buffer springs 7 provide good elasticity and cushioning, allowing the pressure plate 3 to fit tightly against the connecting plate 2 while reducing wear caused by hard contact between the two. In addition, when external force is applied, the rubber soft rods 6 and the buffer springs 7 can absorb part of the force.

[0038] When installing shoe buckles, buckle body 1, connecting plate 2 and pressure plate 3 are installed respectively. The connecting rod 4 on the surface of connecting plate 2 is connected to the rod groove 5 on the surface of buckle body 1 to form an assembly. This assembly is then installed on the shoe upper. Then, the pressure plate 3 and connecting plate 2 are installed at the other end of the shoe upper. Corresponding holes need to be reserved in the shoe upper to facilitate the installation of buckle body 1.

[0039] When the pressure plate 3 and the connecting plate 2 are installed, the rubber flexible rod 6 is engaged with the connecting hole 8. By applying pressure, the connecting rubber block 11 on the surface of the pressure plate 3 is connected with the slot 12, so that the fabric of the shoe upper is located between the connecting plate 2 and the pressure plate 3. Then, the barb 10 on the surface of the mounting bracket 9 is used to hook the fabric of the shoe upper, which plays a hooking role and reduces the probability of the buckle 1 falling off the surface of the shoe upper. This structure allows for the replacement of buckles of different shapes. When it is necessary to remove the buckle, the buckle 1 is removed from the surface of the connecting plate 2, so that the connecting rod 4 and the locking rod 14 are disengaged from the rod slot 5 and the engaging hole 15.

[0040] The barbs 10 are installed at both ends of the mounting bracket 9. One end of the mounting bracket 9 abuts against the surface of the pressure plate 3. The slots 12 are arranged in a ring on the surface of the connecting plate 2. The connecting rubber block 11 and the slot 12 are coaxially arranged. The connecting rubber block 11 is arc-shaped, and the slot 12 has an inward concave structure and is consistent with the shape of the connecting rubber block 11.

[0041] The design of the barb 10 ensures that the fabric of the upper can wrap around the barb 10, reducing the probability of the buckle 1 accidentally coming loose. The circular arrangement of the slots 12 on the surface of the connecting plate 2 helps to evenly distribute the locking force on the surface of the connecting plate 2, avoiding local stress concentration. The coaxial arrangement ensures that the connecting rubber block 11 can be embedded in the slot 12, improving the locking accuracy and reliability. This arrangement reduces the risk of failure caused by misalignment. At the same time, the arc-shaped connecting rubber block 11 combined with the concave slot 12 has a self-locking effect, reducing the probability of the connecting rubber block 11 falling out of the slot 12. In addition, the arc-shaped design makes the locking action smoother, improving the user experience.

[0042] The surface of the barb 10 is connected to a thread-locking hook 13 for locking the upper thread. There is a gap between the thread-locking hook 13 and the mounting frame 9 for winding the upper thread. The design of the thread-locking hook 13 allows the upper thread to be firmly wound between the thread-locking hook 13 and the mounting frame 9, thereby preventing the buckle 1 from loosening or slipping and ensuring that the buckle 1 always maintains the appropriate tightness during wear.

[0043] The surface of the connecting plate 2 is equipped with a locking rod 14 to increase the connection stability between it and the buckle body 1. The buckle body 1 abuts against the locking rod 14 through the locking hole 15. The locking rod 14 and the connecting plate 2 are coaxially arranged. The connecting rod 4 is arranged in a circle with the locking rod 14 as the center point.

[0044] The coaxial design of the locking rod 14 and the connecting plate 2 ensures the alignment accuracy between the two, reduces assembly errors, and enhances overall stability. With the locking rod 14 as the central support point, the pressure from the buckle body 1 can be evenly distributed, avoiding local stress concentration and thus improving the load-bearing capacity. This structure also achieves the effect of uniform force distribution. The connecting rods 4 are arranged around the locking rod 14, so that when the buckle body 1 is subjected to external force, the force is evenly distributed to the connecting plate 2 and the buckle body 1 through the connecting rods 4 and the locking rod 14, which improves the durability of the product.

[0045] The surface of the buckle body 1 is provided with a plurality of weight-reducing grooves 16. The weight-reducing grooves 16 are prismatic and penetrate through the surfaces of both ends of the buckle body 1. By providing weight-reducing grooves 16 on the buckle body 1, the amount of material used in the manufacturing process can be reduced, thereby reducing the total weight of the product. The lighter product is easier to carry and wear. For applications such as sports shoes that need to be worn for a long time, reducing weight can reduce the burden on the feet and improve comfort. In addition, by scientifically designing the position and shape of the weight-reducing grooves 16, the prismatic shape of this structure can achieve the weight reduction goal while ensuring sufficient structural strength. The prismatic design helps to evenly distribute external forces to the entire buckle body structure, avoid local stress concentration, and achieve a stable effect.

[0046] The surface of the buckle body 1 is provided with a plurality of decorative grooves 17, which are non-through structures and are prismatic in shape.

[0047] The use of a diamond-shaped decorative groove 17 adds a unique geometric pattern to the shoe buckle, making the product more attractive. This design can enhance the product's sense of quality and fashion, and can be adjusted to meet the aesthetic needs of different consumers. Since the decorative groove 17 is non-through, it can reduce the weakening of the overall structural strength of the buckle body 1. Compared with the through-type weight-reducing groove 16, this design can achieve a decorative effect without affecting the function, reduce stress concentration problems caused by holes, help prevent cracks or damage during use, and ensure long-term reliability.

[0048] The surface of the buckle body 1 is provided with an anti-slip pad 18 to increase the friction between the buckle body 1 and the shoe surface. The buckle body 1 is in the shape of a four-sided rhombus. The anti-slip pad 18 can improve the friction between the edge of the buckle body 1 and the shoe surface, ensuring that the buckle reduces the probability of slipping or displacement during use, enhancing the stability of the fixation. In addition, the anti-slip pad 18 can evenly distribute the pressure from the buckle, avoiding local pressure on the shoe surface, thereby improving the comfort of wearing. The rhombus structure helps to evenly distribute the external force in four directions, so that the buckle body 1 can better withstand multi-directional tension and reduce the occurrence of deformation or damage.

[0049] The key design features of this utility model are: the use of a rhomboid decorative groove 17 can add a unique geometric pattern to the shoe buckle, making the product appearance more attractive. This design can enhance the product's grade and fashion sense, and the rhomboid structure helps to distribute external forces evenly in four directions, so that the buckle body 1 can better withstand multi-directional tension and reduce deformation or damage.

[0050] The connecting rods 4 are arranged in a ring on the surface of the connecting plate 2 to distribute pressure evenly and ensure a stable connection between the connecting plate 2 and the buckle 1. The non-through grooves 5 help maintain the overall strength of the buckle 1 and avoid structural weakening due to excessive drilling. The rubber soft rods 6 and the buffer springs 7 provide good elasticity and cushioning, allowing the pressure plate 3 to fit tightly against the connecting plate 2 while reducing wear caused by hard contact between the two. In addition, when external force is applied, the rubber soft rods 6 and the buffer springs 7 can absorb part of the force.

[0051] When installing shoe buckles, buckle body 1, connecting plate 2 and pressure plate 3 are installed respectively. The connecting rod 4 on the surface of connecting plate 2 is connected to the rod groove 5 on the surface of buckle body 1 to form an assembly. This assembly is then installed on the shoe upper. Then, the pressure plate 3 and connecting plate 2 are installed at the other end of the shoe upper. Corresponding holes need to be reserved in the shoe upper to facilitate the installation of buckle body 1.

[0052] When the pressure plate 3 and the connecting plate 2 are installed, the rubber flexible rod 6 is engaged with the connecting hole 8. By applying pressure, the connecting rubber block 11 on the surface of the pressure plate 3 is connected with the slot 12, so that the fabric of the shoe upper is located between the connecting plate 2 and the pressure plate 3. Then, the barb 10 on the surface of the mounting bracket 9 hooks the fabric of the shoe upper, which plays a hooking role and reduces the probability of the buckle 1 falling off the surface of the shoe upper.

[0053] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
