Description

Technical Field

[0001] This utility model relates to the field of clothing accessories technology, specifically to a sound-absorbing snap fastener and clothing. Background Technology

[0002] Fasteners are used in clothing, bags, and other daily necessities to close plackets, pockets, collars, and openings. Common fasteners include snap fasteners, which are formed by the combination of a bottom fastener and a top fastener. Multiple fasteners can also be used for larger items such as curtain fasteners and quilt linings. Existing fasteners are insufficient for thick filled fabrics such as down jackets, cotton-padded jackets, fur coats, and lambskin coats. These garments require bottom fasteners with high fastening strength, low-temperature resistance, quiet operation, spring fatigue resistance, and the ability to remain securely in place even after long-term use once embedded in the fabric.

[0003] Existing fastener products have obvious defects: when the elastic element is used in conjunction with the slingshot cup, due to the gap between the elastic element and the slingshot cup, noise is easily generated when the female fastener shakes due to the collision between the elastic element and the slingshot cup. Utility Model Content

[0004] One of the purposes of this invention is to provide a noise-reducing snap button, which solves the problem that the spring component inside the existing snap button is prone to shaking, resulting in a large amount of shaking noise.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A noise-reducing snap fastener includes a female snap and a male snap. The male snap is engaged with the female snap. The female snap includes a base shell, a pressure shell, a spring cup, and an elastic element. The spring cup is fitted into the base shell. The pressure shell is disposed on the base shell and fixes the spring cup. The spring cup has a cavity. The elastic element is disposed in the cavity. One end face of the spring cup is open. The protruding part of the male snap passes through the opening and enters the spring cup to form a snap. The inner wall of the spring cup has a protrusion. The protrusion abuts against the elastic element and restricts the movement of the elastic element in the cavity. After the spring cup is engaged, the connection is firm. The engagement of the elastic element and the male snap provides a strong fastening force. The small contact area of ​​the protrusion after connection results in a quiet snap.

[0007] Preferably, the inner wall of the slingshot cup is provided with a plurality of protrusions, which are distributed at intervals around the axis of the slingshot cup, and the plurality of protrusions cooperate to form a stable connection.

[0008] Furthermore, the male buckle includes a snap-fit ​​part and a cover body. The snap-fit ​​part is installed on the cover body. The protruding part is located on the snap-fit ​​part and is configured to expand outward toward the bottom of the cavity. The snap-fit ​​part has a groove in the middle. After the snap-fit ​​part is snapped into the slingshot cup, the snap-fit ​​part has a strong locking force and can bear a large load.

[0009] Preferably, the elastic element is a copper ring spring, which is wear-resistant and produces little noise upon contact, thus having a noise-dampening effect.

[0010] Furthermore, the slingshot cup is provided with a stepped portion, the elastic element is disposed on the inner wall of the stepped portion, and the protrusion is disposed at the junction of the stepped portion. Part of the protrusion abuts against the elastic element, and another part abuts against the portion of the male buckle that extends into the slingshot cup. The slingshot cup can elastically deform to a certain extent, and the elastic element provides the snapping elasticity and can also limit the maximum amount of deformation.

[0011] Preferably, the slingshot cup has a mounting hole in the middle, which penetrates the slingshot cup and is opposite to the groove for fastener installation, making it suitable for use in high-load bags and clothing.

[0012] Furthermore, the bottom surface of the slingshot cup is provided with anti-slip ridges. The anti-slip ridges expand spirally along the radial direction of the slingshot cup, and multiple anti-slip ridges are evenly distributed around the axis of the slingshot cup to increase the friction between the slingshot cup and the fabric and prevent the slingshot cup from rotating.

[0013] Preferably, the end face of the cover retracts towards the end face of the slingshot cup to form a first inclined surface, and the end face of the pressure shell retracts towards the end face of the cover to form a second inclined surface. The first inclined surface and the second inclined surface form a separation space, which facilitates the user to open and use the clasp.

[0014] Preferably, the pressure shell includes a pressing part and a supporting part. The supporting part surrounds the outer edge of the bottom shell, and the end face of the supporting part abuts against the lower end of the bottom shell. The pressing part abuts against the upper end face of the slingshot cup, so that the connection is firm and reliable and the appearance is beautiful.

[0015] The second objective of this utility model is to provide a garment that solves the problems of easy slippage and wear of existing garment fasteners and fatigue failure after long-term use.

[0016] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0017] A garment comprising the aforementioned noise-absorbing snap, which is attached to fabric and has the advantages of strong fastening force and low noise during use.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) The sound-absorbing snap has an elastic element built into the cavity of the slingshot cup and a protrusion that restricts the movement of the elastic element. Combined with the stepped contact structure between the male snap and the slingshot cup, the hard collision of traditional metal is transformed into elastic buffering, reducing the impact noise at the moment of snapping. The spring is fixed by the protrusion, eliminating the snapping sound caused by the shaking and misalignment of the spring, meeting the usage needs of high-end clothing and quiet scenes.

[0020] (2) The sound-absorbing snap utilizes the low-temperature resistance of the copper ring spring, combined with the spring limit of the protruding part of the slingshot cup step and multiple protrusions to form multi-point contact, which disperses the deformation pressure during contact and reduces the snapping sound. The anti-slip protrusion is set on the bottom shell to increase the resistance to the contact fabric, avoid damage caused by repeated snapping and thick fabric pulling and friction, has a long service life and is not easy to damage clothing, and is suitable for high-end clothing.

[0029] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] Example 1

[0031] like Figures 1-5 As shown, this embodiment discloses a noise-mute snap fastener, including a female snap 1 and a male snap 2. The male snap 2 is snapped onto the female snap 1. The female snap 1 includes a bottom shell 12, a pressure shell 11, a slingshot cup 13, and an elastic element 14. The slingshot cup 13 is fitted onto the bottom shell 12. The pressure shell 11 is disposed on the bottom shell 12 and fixes the slingshot cup 13. The lower part of the pressure shell 11 surrounds the outer edge of the bottom shell 12. The pressure shell 11 and the bottom shell 12 cover the slingshot cup 13. The top of the pressure shell 11 is provided for the male snap 2 to enter. The slingshot cup 13 has a cavity inside the through hole, and the elastic element 14 is disposed in the cavity. One end face of the slingshot cup 13 is open, and the opening is opposite to the through hole. The protruding part of the male buckle 2 passes through the opening and enters the slingshot cup 13 to form a snap-fit. The inner wall of the slingshot cup 13 has a protrusion 131, which abuts against the elastic element 14 to restrict the movement of the elastic element 14 in the cavity. The elastic element 14 is used to provide the elastic force for snapping the male buckle 2 and to limit the maximum deformation displacement to prevent the pressure shell 11 from breaking off.

[0032] Furthermore, the male buckle 2 includes a snap-fit ​​part 21 and a cover 23. The snap-fit ​​part 21 is installed on the cover 23. The protruding part is located on the snap-fit ​​part 21 and is configured to expand outward toward the bottom of the cavity. Specifically, the snap-fit ​​part 21 is an outwardly expanding cone shape, and the middle part of the snap-fit ​​part 21 is provided with a groove 22. The snap-fit ​​part 21 has a certain elasticity. It enters the sling cup 13 through the elastic deformation of the snap-fit ​​part 21 to form a snap. The diameter of the top end of the snap-fit ​​part 21 facing the female buckle 1 is larger than that of the bottom end to prevent the snap-fit ​​part 21 from coming out of the sling cup 13. The fastening force is large and the connection is stable and reliable.

[0033] Preferably, the elastic element 14 is a copper ring spring. Copper elements produce less noise when in contact, which can help to mute the noise. The ring spring has a large clamping force and is not easily damaged.

[0034] Furthermore, the slingshot cup 13 is provided with a stepped portion 133, the elastic element 14 is provided on the inner wall of the stepped portion 133, and the protrusion 131 is provided at the junction of the stepped portion 133, specifically at the junction of the upper and lower steps. Part of the protrusion 131 abuts against the elastic element 14, and another part abuts against the part of the male buckle 2 that extends into the slingshot cup 13. The protrusion 131 is formed by stamping the cup wall of the slingshot cup 13. The protrusion 131 abuts against the side wall of the snap-fit ​​portion 21, directly providing snap-fit ​​pressure. Moreover, the contact surface of the protrusion 131 is small, and the sound is small when snap-fitting, making it more comfortable for the user.

[0035] Preferably, a through groove is provided on the cover 23, and the lower part of the stepped portion 133 of the slingshot cup 13 is fitted into the through groove, and part of the stepped portion 133 extends out of the cover 23 and can contact the fabric.

[0036] More preferably, a recess is provided on the cover 23, and a through groove is provided on the bottom wall of the recess. The stepped part 133 is engaged with the recess, which improves the stability of the connection of the slingshot cup 13, can withstand greater fastening force and has a longer service life.

[0037] Preferably, the slingshot cup 13 has a mounting hole 134 in the middle, the mounting hole 134 penetrates the slingshot cup 13, and the mounting hole 134 is opposite to the groove 22, for direct connection with fasteners, for use in high-load clothing.

[0038] Furthermore, the bottom surface of the slingshot cup 13 is provided with anti-slip ridges 132. The anti-slip ridges 132 expand spirally along the radial direction of the slingshot cup 13. Multiple anti-slip ridges 132 are evenly distributed around the axis of the slingshot cup 13. The anti-slip ridges 132 increase the friction between the slingshot cup 13 and the fabric. The spiral expansion can also prevent the slingshot cup 13 from rotating, resulting in better stability.

[0039] Preferably, the end face of the cover 23 towards the slingshot cup 13 contracts to form a first inclined surface, and the end face of the pressure shell 11 towards the end face of the cover 23 contracts to form a second inclined surface. The first and second inclined surfaces form a separation space, through which the user can remove the male buckle 2 from the female buckle 1, making it more convenient to use.

[0040] Furthermore, the pressure shell 11 includes a pressing part 111 and a supporting part 112. The supporting part 112 surrounds the outer edge of the bottom shell 12, and the end face of the supporting part 112 abuts against the lower end of the bottom shell 12. The pressing part 111 abuts against the upper end face of the slingshot cup 13 to form an elastic pressing. The pressure shell 11 and the bottom shell 12 are stably connected, fixing the slingshot cup 13 between the two and forming a cover. The surface is smooth and the feel is good when used.

[0041] The usage process of this silencer snap is as follows:

[0042] Place the bottom shell 12 inside the fabric connection opening, then place the slingshot cup 13 on the outside of the fabric after aligning it with the recess on the bottom shell 12. Press the slingshot cup 13 down onto the bottom shell 12 so that the slingshot cup 13 fits into the bottom shell 12. Then, align the pressure shell 11 with the bottom shell 12 and apply pressure to the side of the bottom shell 12, pressing the fabric into the pressure shell 11. This causes the inside and outside of the fabric to be subjected to bidirectional pressure, pressing the male buckle 2 into the slingshot cup 13 to complete the closure of the fabric connection opening.

[0043] Example 2

[0044] like Figure 6 As shown, this embodiment also discloses a sound-absorbing snap, which has multiple protrusions 131 on the inner wall of the slingshot cup 13. The multiple protrusions 131 are distributed sequentially around the center of the slingshot cup 13. The multiple protrusions 131 are equally spaced on the inner wall of the step portion 133. The multiple protrusions 131 together restrict the movement of the elastic member 14, making the elastic member 14 more stable.

[0045] Example 3

[0046] This embodiment also discloses a garment, including a sound-absorbing snap and a fabric. The pressure shell 11 of the female snap 1 presses the slingshot cup 13 onto the bottom shell 12. The fabric is sandwiched between the slingshot cup 13 and the bottom shell 12. The anti-slip ridges 132 on the bottom surface of the slingshot cup 13 enhance the friction with the fabric. The spiral anti-slip ridges 132 can effectively prevent the female snap 1 from rotating on the fabric, resulting in better stability and less risk of damaging the fabric with long-term use.

[0047] Preferably, a flange 135 is provided on the inner edge of the mounting hole 134, and the fastener passes through the mounting hole 134 to fix the female buckle 1 to the fabric, which is suitable for heavy-duty use.

[0048] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
