[0033] Snap fasteners are widely used connectors in clothing, bags, shoes, and hats, typically consisting of a snap fastener face and a snap cup. Traditional snap fastener face pieces have a simple structure and single function, usually only serving a connecting purpose. However, in confined spaces or situations requiring one-handed operation, traditional snap fastener face pieces are difficult to use quickly and conveniently for fastening or unfastening.

[0034] To solve the above problems, such as Figures 1 to 2 As shown, this utility model provides a snap fastener and a snap fastener to improve the ease of operation of the snap fastener.

[0035] This application first provides a fastener face piece for a snap fastener, the snap fastener also including a spring cup. For example... Figure 1 As shown, the fastener provided in this application includes a fastening part 1, a fastening part 2, and an operating part 3. The fastening part 2 is disposed on the end face of the fastening part 1 and is used to cooperate with the slingshot cup. The operating part 3 is disposed on the fastening part 1 and is provided with a first through hole 31 for inserting accessories.

[0036] In the snap fastener provided by this utility model embodiment, in the assembled state, the snap fastening part 2 fits tightly with the slingshot cup to ensure the stability of the connection, while the first through hole 31 on the operating part 3 facilitates the insertion of various accessories, such as ropes or pull rings. The cooperation between the accessories and the operating part 3 enables the user to quickly and conveniently fasten or unfasten the snap fastener even in confined spaces or when one-handed operation is required, thereby improving the operational convenience of the snap fastener.

[0037] like Figure 1 As shown, in one embodiment, the operating part 3 is a protruding structure provided on the end face of the fastening part 1 opposite to the fastening part 2. This design makes the operating part 3 of the protruding structure easy for the user to pinch or pull, providing better operational convenience, especially in scenarios requiring frequent adjustments or installation / disassembly. The location of the operating part 3 on the end face makes the layout of the fastening part more compact in the radial direction, saving space, wherein the radial direction is parallel to the end face of the fastening part 1.

[0038] like Figure 1 As shown, in one embodiment, the cross-sectional area of ​​the operating part 3 gradually decreases from the end near the fastening surface 1 to the end away from the fastening surface 1. This configuration allows the operating part 3 to reduce its weight while maintaining strength, and its shape is more streamlined, making it easier for the user to pinch or pull, and also facilitating the insertion and operation of accessories.

[0039] In another embodiment, the operating part 3 can be a protruding structure of various shapes, such as cylindrical, conical, hemispherical, etc. The size and shape of the operating part 3 can be adjusted according to actual needs.

[0040] In another embodiment, the protrusion of the operating part 3 can be designed with a non-slip texture to increase friction and prevent slippage during operation.

[0041] like Figure 1 As shown, in one embodiment, the extension direction of the first through hole 31 is parallel to the end face of the buckle face 1, ensuring that the accessory can be subjected to force in the horizontal direction after it is inserted, and avoiding the buckle face from loosening due to vertical force.

[0042] The operation unit 3 may be provided with one or more first through holes 31 to meet different application requirements.

[0043] The first through hole 31 can be any shape, such as circular, elliptical, or square.

[0044] In another embodiment, the extension direction of the first through hole 31 can be at a certain angle to the end face of the buckle face 1 to meet special assembly requirements.

[0045] like Figure 2 As shown, in one embodiment, the operating part 3 is disposed on the side of the snap fastener part 1. This arrangement, with the operating part 3 located on the side, makes the layout of the snap fastener part in the thickness direction more compact, saving space, wherein the thickness direction is perpendicular to the end face of the snap fastener part 1. When the snap fastener is installed in a confined area, the side-mounted operating part 3 facilitates the application of force from the side.

[0046] In another embodiment, the position and orientation of the operating part 3 on the side can be flexibly adjusted. For example, the operating part 3 can be set on different sides of the snap fastener 1, or tilted at a certain angle, to adapt to different assembly directions and operational needs. Specifically, the operating part 3 can be set on the left, right, upper, or lower side of the snap fastener 1, depending on the actual usage scenario and assembly requirements of the snap fastener. For example, in some applications, setting the operating part 3 on the upper side of the snap fastener 1 makes it easier for the user to press and operate with their thumb or forefinger; in other applications, setting it on the lower side is more ergonomic and makes it easier to hook and pull with other fingers. In addition, the operating part 3 can also be tilted at a certain angle, such as forming different angles of 30 degrees, 45 degrees, or 60 degrees with the snap fastener 1. This tilting setting can help the operating part 3 better avoid interference from other components, or in special assembly environments, ensure that the direction of the operating part 3 is consistent with the assembly direction, facilitating installation and disassembly.

[0047] like Figure 2 As shown, in one embodiment, the operating part 3 covers the outer periphery of the fastening part 1. The covering structure can enhance the overall structural strength of the fastening part, making the fastening part more robust and durable.

[0048] In another embodiment, the operating part 3 protrudes only in a local area on the side of the fastener 1, forming a small boss or columnar structure, which can effectively save space and is suitable for scenarios where assembly space is limited.

[0049] like Figure 2 As shown, in one embodiment, the extension direction of the first through hole 31 is perpendicular to the end face of the buckle face 1. The design of the vertical through hole allows the fitting to be as close as possible to the buckle face, reducing the volume of the overall structure and saving space.

[0050] The operation unit 3 may be provided with one or more first through holes 31 to meet different application requirements.

[0051] The first through hole 31 can be any shape, such as circular, elliptical, or square.

[0052] In another embodiment, the extension direction of the first through hole 31 can be at a certain angle to the end face of the buckle face 1 to meet special assembly requirements.

[0053] like Figure 1 As shown, in one embodiment, one of the fastening part 1 and the operating part 3 is provided with a mounting groove 32, and the other is provided with a mounting part 11 that cooperates with and limits the mounting groove 32. With this arrangement, the cooperation between the mounting groove 32 and the mounting part 11 achieves a reliable connection between the fastening part 1 and the operating part 3, which facilitates assembly and disassembly, and makes it easy to replace the operating part 3 of different specifications to adapt to different accessories.

[0054] The mounting groove 32 can be a groove of various shapes, such as a straight groove, an arc groove, or a trapezoidal groove. The size and shape of the mounting groove 32 can be adjusted according to actual needs. The mounting part 11 can be a protruding structure of various shapes, such as a tenon or a snap fastener. The size and shape of the mounting part 11 are adapted to the mounting groove 32. Various connection methods can be used between the mounting groove 32 and the mounting part 11, such as snap fasteners, threaded connections, or adhesive connections.

[0055] like Figure 2 As shown, in one embodiment, when the operating part 3 covers the outer periphery of the fastening part 1, the operating part 3 is provided with a mounting groove 32, and the bottom wall of the mounting groove 32 is provided with a second through hole 321. The fastening part 1 is provided with a mounting part 11, and a fastening part 2 is provided on the end face of the mounting part 11. The mounting part 11 is embedded in the mounting groove 32, and the fastening part 2 extends out of the mounting groove 32 through the second through hole 321. With this configuration, the operating part 3 is connected to the fastening part 1 through the mounting groove 32, and the fastening part 2 passes through the second through hole 321 to cooperate with the slingshot cup, further fixing the operating part 3 to the fastening part 1 and preventing it from falling off during use.

[0056] like Figure 2 As shown, in one embodiment, the cross-section of the fastening part 1 is a non-rotational body, and the cross-sectional shape of the mounting groove 32 is adapted to the cross-sectional shape of the fastening part 1. This configuration, with its non-rotational cross-sectional shape, gives the fastening part 1 better stability and torsional resistance, while the adapted mounting groove 32 cross-sectional shape ensures precise fit when the operating part 3 is connected to the fastening part 1.

[0057] In the illustrated embodiment, the mounting part 11 has a grooved circle in cross-section, and the mounting groove 32 has a raised circle in cross-section that matches the cross-sectional shape of the snap fastener 1. Alternatively, depending on the overall design requirements of the snap fastener, the cross-section of the snap fastener 1 can be a non-rotational body of various shapes, such as triangles, squares, polygons, etc., and the cross-sectional shape of the mounting groove 32 can be adjusted accordingly to achieve the best fit.

[0058] In another embodiment, when the operating part 3 protrudes only in a local area on the side of the fastening part 1, the mounting part 11 can be a protrusion protruding from the side wall of one of the fastening part 1 and the operating part 3, and the mounting groove 32 is a groove provided on the side wall of the other, with the groove and the protrusion engaging.

[0059] In another embodiment, the operating part 3 and the snap fastener part 1 are integrally formed. This integral forming structure eliminates gaps between components, improves structural strength and durability, extends the service life of the snap fastener, simplifies the manufacturing process, and reduces production costs.

[0060] In one embodiment, the fastening part 1 and the fastening portion 2 are integrally formed. In another embodiment, the fastening part 1 and the fastening portion 2 are separate and connected by means of snap-fit, thread, adhesive, or other methods.

[0061] This utility model also provides a snap fastener, including the aforementioned fastener face piece. With this design, the snap fastener not only possesses a reliable fastening function, but also achieves improved ease of operation, versatility, and durability through the optimized design of the fastener face piece.

[0062] In one embodiment, the snap fastener also includes a fitting, such as a rope or a pull ring, that passes through the first through hole 31. This arrangement, with the fitting such as a rope or pull ring passing through the first through hole 31 of the operating part 3, provides additional operational convenience and functional expandability.

[0063] Depending on the characteristics of the application scenario, the accessory rope or pull ring can be made of materials such as TPU, silicone, nylon or polyester fiber.

[0064] In another embodiment, the accessories can be replaced with chains, elastic bands, or metal hooks to expand the application scenarios of snap fasteners. For example, chain accessories are suitable for decorative snap fasteners, elastic band accessories are suitable for scenarios requiring flexible connections, and metal hook accessories are suitable for applications with heavy loads. The structure of the operating part 3 can be adjusted according to the type of accessory; for example, when a metal hook is used, the operating part 3 can be thickened or reinforced to increase tensile strength.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
