Description

Technical Field

[0001] This utility model relates to the field of jewelry technology, and in particular to a decorative buckle. Background Technology

[0002] Decorative buckles, as a common accessory, are widely used in clothing, bags, shoes, and hats, serving as functional connectors or aesthetic decorative elements. They typically consist of a base, a buckle body, and a decorative section, used to secure fabric or provide visual embellishment. With the continuous evolution of fashion trends and the increasing demand for personalization among consumers, the styles and functions of decorative buckles have become increasingly diverse, making them an important element for showcasing individuality and enhancing product value.

[0003] While the design and application of decorative buckles are relatively mature in current technology, they still have certain limitations in meeting users' needs for personalization and convenient style changes. Consumers often hope to be able to flexibly change the style of decorative buckles according to different occasions, outfits, or moods to achieve richer matching effects, thereby extending the lifespan of clothing or bags and increasing their fashion sense. However, most decorative buckles on the market currently do not fully consider this replaceability in their design.

[0004] Most existing decorative items are secured with pins or clips. Pins can easily pierce the fabric, leaving irreversible marks and posing safety hazards; clips can easily deform or loosen the fabric, resulting in poor securing effects. These traditional securing methods limit the convenience and application range of decorative items. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to propose a decorative buckle that solves the problem that existing decorative buckles require complete disassembly when changing decorative styles.

[0006] To achieve this objective, the present invention adopts the following technical solution: A decorative buckle includes a retaining ring, a female buckle, a male buckle, and a decorative cap. The retaining ring and the female buckle are disposed opposite each other on both sides of a fabric. The retaining ring and the female buckle are used to clamp the fabric. The male buckle is detachably installed on the female buckle. The decorative cap is connected to the end of the male buckle away from the female buckle.

[0007] Preferably, the female buckle includes a mounting base and a fastening part. The mounting base is a straight round tube with internal threads. The fastening part is connected to one end of the mounting base in the axial direction. The female buckle includes a connecting shaft. The outer side of the connecting shaft is provided with an external thread that matches the internal thread of the mounting base.

[0008] Preferably, the fastening part has a limiting protrusion on the side near the mounting base, and the limiting protrusion is connected to the inner wall of the mounting base. The outer edge of one end of the connecting shaft has a limiting groove. When the connecting shaft is tightened to the mounting base, the limiting protrusion is embedded in the limiting groove.

[0009] Preferably, a plurality of limiting grooves are provided, and the plurality of limiting grooves are equally spaced along the circumference of the connecting shaft.

[0010] Preferably, there are a plurality of limiting protrusions, which are evenly spaced along the circumference and correspond one-to-one with the plurality of limiting grooves.

[0011] Preferably, the plurality of limiting protrusions are arranged in pairs, and the two pairs of limiting protrusions are connected to form a reinforcing rib. The plurality of reinforcing ribs are arranged intersectingly along the diameter direction of the mounting base. The fastening part, the mounting base, the plurality of limiting protrusions and the plurality of reinforcing ribs are integrally formed.

[0012] Preferably, the sub-button further includes a connecting plate, the diameter of which is 1.5 to 2 times the diameter of the connecting shaft. The connecting plate and the connecting shaft are integrally formed, and the decorative cap is bonded to the connecting shaft through the connecting plate.

[0013] Preferably, the connecting shaft is a hollow tube with a thickness of 0.5~1mm.

[0014] Preferably, the retaining ring adopts a five-claw bottom buckle, and the fastening part is pressed and locked with the retaining ring.

[0015] Preferably, the fixing ring and the female buckle are integrally formed iron or copper parts, the female buckle is integrally formed iron, copper or rigid plastic part, and the decorative cap is a plastic or silicone part.

[0016] The technical solution provided by this utility model can include the following beneficial effects: 1. This decorative buckle aims to solve the problem of inconvenience caused by the need for complete disassembly or even damage to the original buckle when changing the decorative style of existing decorative buckles. For example... Figure 1 As shown, by incorporating a detachable female buckle attached to the female buckle and a decorative cap connecting to it, users can easily replace the decorative cap with different styles, colors, or materials to match their clothing or personal preferences. Simply remove and replace the decorative cap and female buckle together, without replacing or damaging the female buckle and retaining ring fixed to the fabric. This greatly enhances the flexibility and lifespan of the decorative buckle, while reducing replacement costs and providing diverse decorative options. Furthermore, this decorative buckle can be used as a standalone decorative piece or combined with buttonholes on clothing, further expanding its application range.

[0017] 2. The internal thread of the female buckle's mounting base matches the external thread of the male buckle's connecting shaft, achieving a threaded locking connection between the female and male buckles. This structure not only provides a robust and reliable mechanical connection, effectively preventing accidental loosening due to vibration or external force during use, but also simplifies operation; users can complete installation or disassembly simply by rotating the male buckle, greatly improving ease of use and safety.

[0018] 3. By setting a limiting protrusion at the female buckle's engagement part and a corresponding limiting groove on the outer edge of the male buckle's connecting shaft, the limiting protrusion precisely engages with the limiting groove when the male buckle is tightened onto the female buckle. This design provides additional mechanical limiting on top of threaded locking, effectively preventing the male buckle from loosening due to external vibration or rotational force, significantly enhancing the stability and reliability of the connection, and ensuring that the decorative buckle maintains a tight connection in various usage scenarios. This solves the problem of spontaneous loosening that may occur with simple threaded connections over long-term use, thus affecting the reliability of the decorative buckle connection.

[0019] 4. By setting multiple equally spaced limiting grooves along the circumference of the connecting shaft, the circumferential limiting of the connecting shaft can be achieved by the limiting protrusion embedding into any one of the limiting grooves. This effectively reduces the matching accuracy requirements of the thread and the limiting groove during the manufacturing process, allows for a certain degree of manufacturing tolerance, simplifies the production process, reduces the scrap rate, and thus reduces the overall manufacturing cost. Furthermore, even if the decorative buckle deforms slightly during long-term use, causing a mismatch between the limiting protrusion and the limiting groove, the presence of multiple limiting grooves still ensures that the limiting protrusion has a suitable position to engage when tightened, guaranteeing the effective implementation of the limiting function and not affecting its anti-loosening effect.

[0020] 5. By setting multiple circumferentially spaced limiting protrusions that correspond one-to-one with multiple limiting grooves, multi-point limiting ensures that the locking force is evenly distributed circumferentially on the connecting shaft. This effectively avoids excessive stress on a single or a few limiting points, thus preventing component wear, deformation, or damage caused by localized stress concentration. This not only significantly improves the overall stability and durability of the limiting structure but also ensures that the decorative buckle maintains reliable anti-loosening performance even under long-term high-intensity use.

[0021] 6. The limiting protrusions are connected to form several reinforcing ribs. These reinforcing ribs are arranged along the diameter of the mounting base, intersecting to form a star-shaped structure, and are integrally formed with the fastening part and the mounting base. This integrally formed reinforcing rib structure greatly enhances the overall rigidity of the limiting protrusions, effectively preventing damage to the limiting protrusions due to uneven force or fatigue during use, thereby ensuring the long-term stability and reliability of the anti-loosening function.

[0032] A decorative buckle includes a fixing ring 1, a female buckle 2, a male buckle 3, and a decorative cap 4. The fixing ring 1 and the female buckle 2 are disposed opposite each other on both sides of a fabric. The fixing ring 1 and the female buckle 2 are used to clamp the fabric. The male buckle 3 is detachably installed on the female buckle 2. The decorative cap 4 is connected to the end of the male buckle 3 away from the female buckle 2.

[0033] This decorative buckle aims to solve the problem of inconvenience caused by the need for complete disassembly, or even damage to the original buckle, when changing the decorative style of existing decorative buckles. For example... Figure 1 As shown, by providing a detachable female buckle 3 attached to the female buckle 2, and a decorative cap 4 connecting to the female buckle 3, users can easily replace the decorative cap 4 with different styles, colors, or materials according to clothing matching or personal preferences. They only need to remove and replace the decorative cap and female buckle together, without replacing or damaging the female buckle 2 and the fixing ring 1 fixed to the fabric. This greatly improves the flexibility and lifespan of the decorative buckle, while reducing replacement costs and providing diverse decorative options. Furthermore, this decorative buckle can be used as an independent decorative piece or combined with buttonholes on clothing, further expanding its application range.

[0034] Preferably, the female buckle 2 includes a mounting base 21 and a fastening part 22. The mounting base 21 is a straight round tube with internal threads. The fastening part 22 is connected to one end of the mounting base 21 in the axial direction. The female buckle 3 includes a connecting shaft 31. The outer side of the connecting shaft 31 is provided with an external thread that matches the internal thread of the mounting base 21.

[0035] like Figure 1 and Figure 2 As shown, the internal thread of the mounting base 21 of the female buckle 2 matches the external thread of the connecting shaft 31 of the male buckle 3, achieving a threaded locking connection between the male buckle 3 and the female buckle 2. This structure not only provides a stable and reliable mechanical connection, effectively preventing accidental loosening due to vibration or external force during use, but also simplifies operation. Users can complete the installation or disassembly simply by rotating the male buckle 3, greatly improving the convenience and safety of use.

[0036] Preferably, the fastening part 22 is provided with a limiting protrusion 221 on the side near the mounting base 21, and the limiting protrusion 221 is connected to the inner wall of the mounting base 21. The outer edge of one end of the connecting shaft 31 is provided with a limiting groove 311. When the connecting shaft 31 is tightened to the mounting base 21, the limiting protrusion 221 is embedded in the limiting groove 311.

[0037] By providing a limiting protrusion 221 at the engaging part 22 of the female buckle 2 and a corresponding limiting groove 311 on the outer edge of the connecting shaft 31 of the male buckle 3, the limiting protrusion 221 precisely engages with the limiting groove 311 when the male buckle 3 is tightened onto the female buckle 2. This design provides additional mechanical limiting on top of threaded locking, effectively preventing the male buckle 3 from loosening due to external vibration or rotational force, significantly enhancing the stability and reliability of the connection, and ensuring that the decorative buckle maintains a tight connection in various usage scenarios. This solves the problem that simple threaded connections may loosen spontaneously over long-term use, thus affecting the reliability of the decorative buckle connection.

[0038] In a specific embodiment, the contact surface between the limiting protrusion 221 and the limiting groove 311 is an arc surface, and the arc surface protrudes away from the fastening part, with the axis of the arc surface arranged radially along the mounting base 21. When the connecting shaft 31 is tightened onto the mounting base 21, the arc surface of the limiting protrusion 221 allows it to be embedded into the limiting groove 311 with a smooth transition. As a simple alternative, a triangular or other limiting protrusion 221 with a sloped transition surface can also be provided.

[0039] In actual operation, when the user screws the connecting shaft 31 of the male buckle 3 into the mounting base 21 of the female buckle 2, the connecting shaft 31 gradually approaches the buckling part 22 as the threads are tightened. When the threads are tightened to the end, the limiting protrusion 221 and the limiting groove 311 begin to contact. Especially when the contact surface between the limiting protrusion 221 and the limiting groove 311 is an arc surface or other transition surface with a slope, the user only needs to apply a certain tightening force, and the limiting protrusion 221 will smoothly slide into and lock into the limiting groove 311 under slight elastic deformation, forming a clear locking sensation. At this time, the male buckle 3 and the female buckle 2 are not only tightly connected by threads, but also achieve double locking through the limiting structure composed of the limiting protrusion 221 and the limiting groove 311, effectively resisting loosening. If disassembly is required, the user needs to apply a reverse rotational force slightly greater than the locking force, so that the limiting protrusion 221 disengages from the limiting groove 311 under elastic deformation, and then the male buckle 3 can be easily screwed out of the female buckle 2. This structure ensures the stability of the connection between the female and male buckles, while also providing clear operational feedback and easy disassembly.

[0040] Preferably, a plurality of limiting grooves 311 are provided, and the plurality of limiting grooves 311 are equally spaced along the circumference of the connecting shaft 31.

[0041] like Figure 3 As shown, by setting multiple circumferentially spaced limiting grooves 311 along the connecting shaft 31, the limiting protrusion 221 can be embedded into any one of the limiting grooves 311 to achieve circumferential limiting of the connecting shaft 31. This effectively reduces the matching accuracy requirements of the thread and the limiting groove 311 during the manufacturing process, allows for a certain degree of manufacturing tolerance, simplifies the production process, reduces the scrap rate, and thus reduces the overall manufacturing cost. Furthermore, even if the decorative buckle deforms slightly during long-term use, causing a matching deviation between the limiting protrusion 221 and the limiting groove 311, the presence of multiple limiting grooves 311 still ensures that the limiting protrusion 221 has a suitable position to engage when tightened, guaranteeing the effective implementation of the limiting function and not affecting its anti-loosening effect.

[0042] Preferably, there are a plurality of limiting protrusions 221, which are evenly spaced along the circumference and correspond one-to-one with the plurality of limiting grooves 311.

[0043] By setting multiple circumferentially spaced limiting protrusions 221, which correspond one-to-one with multiple limiting grooves 311, multi-point limiting ensures that the locking force is evenly distributed circumferentially on the connecting shaft 31. This effectively avoids excessive stress on a single or a few limiting points, thereby preventing component wear, deformation, or damage caused by localized stress concentration. This not only significantly improves the overall stability and durability of the limiting structure but also ensures that the decorative buckle maintains reliable anti-loosening performance even under long-term high-intensity use.

[0044] Preferably, the plurality of limiting protrusions 221 are arranged in pairs, and the two pairs of limiting protrusions 221 are connected to form reinforcing ribs 222. The plurality of reinforcing ribs 222 are arranged intersectingly along the diameter direction of the mounting base 21. The fastening part 22, the mounting base 21, the plurality of limiting protrusions 221 and the plurality of reinforcing ribs 222 are integrally formed.

[0045] like Figure 4 and Figure 5 As shown, to further enhance the strength and reliability of the limiting structure, the limiting protrusions 221 are connected to form several reinforcing ribs 222. These reinforcing ribs 222 are arranged along the diameter direction of the mounting base 21, intersecting to form a star-shaped structure, and are integrally formed with the fastening part 22 and the mounting base 21. This integrally formed reinforcing rib 222 structure greatly enhances the overall rigidity of the limiting protrusions 221, effectively preventing the limiting protrusions 221 from breaking due to uneven force or fatigue during use, thereby ensuring the long-term stability and reliability of the anti-loosening function.

[0046] Preferably, the sub-button 3 further includes a connecting disc 32, the diameter of which is 1.5 to 2 times the diameter of the connecting shaft 31. The connecting disc 32 and the connecting shaft 31 are integrally formed, and the decorative cap 4 is bonded to the connecting shaft 31 through the connecting disc 32.

[0047] The connecting disc 32 significantly increases the bonding area between the decorative cap 4 and the buckle 3, thereby greatly improving the bonding strength and firmness, and effectively preventing the decorative cap 4 from accidentally falling off during use. The one-piece molded connecting disc 32 and connecting shaft 31 structure ensures the overall strength of the connection.

[0048] Preferably, the connecting shaft 31 is a hollow tube with a thickness of 0.5~1mm.

[0049] While ensuring that the connecting shaft 31 has sufficient structural strength and load-bearing capacity, it effectively saves material consumption and significantly reduces production costs. The hollow structure also helps to reduce the overall weight of the decorative buckle and improve wearing comfort.

[0050] Preferably, the fixing ring 1 adopts a five-claw bottom buckle, and the fastening part 22 is pressed and locked with the fixing ring 1.

[0051] The retaining ring 1 adopts a mature and reliable five-pronged bottom buckle structure, and is locked to the fastening part 22 of the female buckle 2 by pressing. This fixing method draws on the advantages of existing five-pronged buckles, which can form a firm and non-loose clamp to the fabric, ensuring that the decorative buckle is securely fixed to clothing or other fabric products. Its installation process is simple and efficient, and can be completed using standard snap-on tools, ensuring that the decorative buckle will not easily fall off during daily use.

[0052] Preferably, the fixing ring 1 and the female buckle 2 are integrally formed iron or copper parts, the female buckle 3 is integrally formed iron, copper or rigid plastic parts, and the decorative cap 4 is a plastic or silicone part.

[0053] The decorative buckle offers diverse material options. The fixing ring 1 and the female buckle 2 can be made of one-piece molded iron or copper to ensure structural strength and durability, while providing a pleasant metallic feel. The female buckle 3 can be made of one-piece molded iron, copper, or rigid plastic to balance different requirements such as strength, cost, and weight. The decorative cap 4 can be made of plastic or silicone, allowing for a rich variety of colors, shapes, and textures, providing greater design flexibility, and allowing for the selection of durable or soft materials based on specific decorative needs. This flexible material combination enables the decorative buckle to adapt to product requirements of different grades, styles, and usage environments, effectively controlling costs and enhancing product competitiveness.
