[0002] Snap buttons are a common clothing accessory, typically used to secure collars, cuffs, pockets, and other areas of clothing. They consist of four cooperating components: a face button, a female button, a sub-button, and a spike. Their simple yet practical design provides excellent fastening while also adding a decorative touch. Snap buttons are widely used in clothing production and everyday wear.

[0003] In the prior art, snap fasteners are generally made of metal. During the fastening process, a metallic clashing sound is produced. However, certain situations have specific noise requirements, such as hunting or animal photography, where even the slightest sound can easily startle an animal. Therefore, existing metal snap fasteners struggle to meet these noise requirements. Summary of the Invention

[0004] In view of this, the utility model provides a silent four-button buckle which makes no sound when fastened.

[0005] A silent and soundless four-button buckle comprises a face buckle, a female buckle fixedly connected to the face buckle, a male buckle matched with the female buckle, and a long nail for fixing the male buckle. The female buckle comprises a silent buckle and a metal buckle shell arranged on the outside of the silent buckle. The silent buckle comprises a silent buckle body, a connecting through hole arranged on the silent buckle body, a limiting ring arranged in the connecting through hole, an abutting ridge arranged on one side of the silent buckle body, and at least one exhaust groove arranged on the silent buckle body. When the female buckle and the male buckle are fastened together, the male buckle is inserted into the connecting through hole and abuts against the abutting ridge. The silent buckle is made of plastic or rubber.

[0006] Furthermore, the connecting through hole includes a through hole body and an inlet arranged at one end of the through hole body, the outer contour of the inlet is arranged in a truncated cone shape, and the end of the inlet with a large diameter is opposite to the through hole body.

[0007] Furthermore, the limiting ring is arranged at the junction of the through hole body and the introduction port, and the limiting ring is arranged in a circular ring shape.

[0008] Furthermore, the abutting ridge is an annular ridge provided at one end of the introduction port toward the male buckle, and the height of the abutting ridge along the axial direction of the female buckle toward the male buckle is higher than the height of the metal buckle shell.

[0009] Furthermore, the exhaust grooves are arranged at equal intervals along the circumferential direction of the abutting edge.

[0010] Furthermore, the metal buckle shell includes a shell, a buckle mounting hole arranged on the shell and used to install the buckle, a buckle body accommodating cavity arranged in the shell, and a buckle edge arranged on one side of the shell.

[0011] Furthermore, the silent buckle body is made of plastic, its shape matches the buckle body accommodating cavity, and is accommodated in the buckle body accommodating cavity.

[0012] Furthermore, the face buckle mounting hole is arranged at the bottom of the shell, the face buckle mounting hole is concentrically arranged with the through hole body, and the diameter of the face buckle mounting hole is smaller than the diameter of the through hole body.

[0013] Compared with the prior art, the silent and soundless snap fastener provided by the present invention has a female buckle including a silent buckle and a metal buckle shell arranged on the outside of the silent buckle. The silent buckle includes a silent buckle body, a connecting through hole arranged on the silent buckle body, a limiting ring arranged in the connecting through hole, an abutting ridge arranged on one side of the silent buckle body, and at least one exhaust groove arranged on the silent buckle body. When the female buckle is fastened with the male buckle, the male buckle is inserted into the connecting through hole and abuts against the abutting ridge.

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the scope of protection of the present invention.

[0018] like Figures 1 to 3, which is a schematic structural diagram of a silent snap fastener provided by the present invention. The silent snap fastener comprises a face buckle 10, a female buckle 20 fixedly connected to the face buckle 10, a male buckle 30 matching the female buckle 10, and a spike 40 for securing the male buckle 30. It is conceivable that the silent snap fastener may also include other functional components, such as assembly components and decorative components. These are well known to those skilled in the art and will not be further elaborated here.

[0019] The face buckle 10 is the visible part of the silent snap buckle when in use. The face buckle 10 is used to fix the female buckle 20 and has a certain decorative effect. The face buckle 10 includes a face buckle body 11, and a female buckle connecting shaft 12 fixedly connected to the face buckle body 11. The face buckle body 11 is usually circular in design, or designed into other shapes according to aesthetic requirements, such as a polygonal structure. Preferably, a pattern or design can be set as decoration on the side of the face buckle body 11 opposite to the female buckle connecting shaft 12, so that the silent snap buckle fixes the female buckle 20 while having a certain decorative effect. The female buckle connecting shaft 12 is a hollow tube structure. The female buckle connecting shaft 12 is used to connect the female buckle 20. The face buckle 10 itself is a prior art known to those skilled in the art and will not be described in detail here.

[0020] The female buckle 20 includes a silent buckle 21 and a metal buckle shell 22 arranged on the outside of the silent buckle 21.

[0021] The silent buckle 21 includes a silent buckle body 211, a connecting through hole 212 arranged on the silent buckle body 211, a limiting ring 213 arranged in the connecting through hole 212, an abutting edge 214 arranged on one side of the silent buckle body 211, and at least one exhaust groove 215 arranged on the silent buckle body 211.

[0022] The silent buckle body 211 is made of silent material, such as plastic, rubber, etc., so as to avoid the metal collision sound between the female buckle 20 and the male buckle 30 when the metal four-piece buckle is fastened.

[0023] The connecting through hole 212 is used to accommodate the connecting portion of the male buckle 30, so as to facilitate the buckling of the female buckle 20 and the male buckle 30. The connecting through hole 212 passes through the silent buckle body 211 along the axial direction of the silent buckle body 211. The connecting through hole 212 includes a through hole body 2121 and an inlet 2122 arranged at one end of the through hole body 2121. The outer contour of the inlet 2122 is arranged in a truncated cone shape, that is, the diameters of the two ends of the inlet 2122 are inconsistent, so that the side wall of the inlet 2122 is an inclined structure. The large-diameter end of the inlet 2122 is opposite to the through hole body 2121, so as to facilitate the insertion of the male buckle 30 into the connecting through hole 212. The diameter of the side of the inlet 2122 close to the through hole body 2121 matches that of the through hole body 2121.

[0024] The retaining ring 213 is disposed at the intersection of the through-hole body 2121 and the inlet 2122. The retaining ring 213 is annular and fixedly connected to the silent buckle body 211. The retaining ring 213 is used to position the male buckle 30 after the female buckle 20 and the male buckle 30 are engaged, thereby ensuring the stability and securement of the engagement between the female buckle 20 and the male buckle 30. The specific connection and fixation method will be described in detail below in conjunction with the male buckle 30.

[0025] The abutting ridge 214 is an annular ridge provided on the end of the introduction port 2122 facing the male buckle 30. The height of the abutting ridge 214 on the side of the female buckle 20 facing the male buckle 30 is higher than the height of the metal buckle shell 22. Therefore, when the female buckle 20 and the male buckle 30 are fastened together, the buckle surface of the male buckle 30 and the abutting ridge 214 abut against each other, thereby preventing the male buckle 30 from contacting and making a collision sound with the metal buckle shell 22.

[0026] In this embodiment, three venting grooves 215 are provided, and the three venting grooves 215 are evenly spaced along the circumferential direction of the abutting ridge 214. The venting grooves 215 are provided along the direction in which the male buckle 30 is buckled in, that is, from the abutting ridge 214 toward the side of the through-hole body 2121. The provision of the venting grooves 215 prevents the silent body 21 from tightly fitting with the buckle surface of the male buckle 30 when the female buckle 20 and the male buckle 30 are in engagement, which could easily cause a sound to be emitted when the female buckle 20 and the male buckle 30 are separated. Furthermore, the opening depth of the venting grooves 215 at least extends through the inlet 2122, thereby preventing air from being trapped in the connecting through-hole 212 when the male buckle 30 is buckled into the female buckle 20, thereby preventing a "snap" sound from being emitted when the male buckle 30 is pulled out.

[0027] The metal buckle shell 22 includes a shell 221, a buckle mounting hole 222 arranged on the shell 221 and used to install the buckle 10, a buckle body accommodating cavity 223 arranged in the shell 221, and a buckle edge 224 arranged on one side of the shell 221.

[0028] The shell 221 is made of metal and is covered on the outside of the silent buckle body 211 to provide support and protection for the silent buckle body 211.

[0029] The face buckle mounting hole 222 is provided at the bottom of the housing 221, that is, on the side of the housing 221 close to the face buckle 10. The face buckle mounting hole 222 is concentric with the through-hole body 2121, and the diameter of the face buckle mounting hole 222 is smaller than the diameter of the through-hole body 2121. Therefore, when the housing 221 is covered on the silent buckle body 211, the face buckle mounting hole 222 forms a circular ring structure at one end of the through-hole body 2121, thereby facilitating the installation of the face buckle 10 on the circular ring structure, connecting the face buckle 10 and the female buckle 20 together and fixing them on the clothing.

[0030] The buckle body accommodating cavity 223 is configured to match the structural shape of the silent buckle body 211 and is used to accommodate the silent buckle body 211, thereby fixing the silent buckle body 211 in the metal buckle shell 22.

[0031] The snap-fit edge 224 is provided on a side of the housing 221 opposite to the face buckle mounting hole 222. The snap-fit edge 224 can be formed by curling the housing 221 after the silent buckle body 211 is installed in the buckle body accommodating cavity 223. The inner diameter of the snap-fit edge 224 is smaller than the outer diameter of the silent buckle body 211, thereby confining the silent buckle body 211 within the buckle body accommodating cavity 223, so that the silent buckle body 211 and the metal buckle housing 22 form a single unit.

[0032] The male buckle 30 includes a male buckle surface 31 and a female buckle insertion post 32 disposed on one side of the male buckle surface 31. The buckle surface 31 is used to mount the female buckle insertion post 32. When the male buckle 30 is engaged with the female buckle 20, the female buckle insertion post 32 is inserted into the connecting through-hole 212, thereby fastening the male buckle 30 and the female buckle 20 together. The male buckle itself is well known to those skilled in the art and will not be further described here.

[0033] The long spike 40 is arranged in pairs with the male button 30, and the long spike 40 is used to install the male button 30 in places where a snap button is required, such as clothing and bags. The long spike 40 itself is well known to those skilled in the art and will not be described in detail here.

[0034] Compared with the prior art, the silent snap fastener provided by the present invention has a female buckle 20 comprising a silent buckle 21 and a metal buckle shell 22 disposed outside the silent buckle 21. The female buckle 20 and the silent buckle 21 comprise a silent buckle body 211, a connecting through-hole 212 disposed on the silent buckle body 211, a limiting ring 213 disposed within the connecting through-hole 212, an abutting ridge 214 disposed on one side of the silent buckle body 211, and at least one exhaust groove 215 disposed on the silent buckle body 211. When the female buckle 20 and the male buckle 30 are fastened together, the male buckle 30 is inserted into the connecting through hole 212 and abuts against the abutting edge 214. Therefore, in the process of fastening the silent four-button buckle, the contact area between the male buckle 30 and the female buckle 20 is reduced. At the same time, the silent buckle 21 is made of silent materials such as plastic, rubber, etc., and there is no metal collision during the fastening process, so that the silent four-button buckle will not make any collision sound during the fastening and opening processes.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
