Problems solved by technology

[0003] In the current snap button structure, the face buckle used to connect with the male and female snaps mostly adopts an integrated structure, and the shape and pattern of the face buckle often have various changes according to the design requirements. The integrally formed structure makes the face buckle The feet must be made of the same material, which limits the selection of materials; even if the pattern or shape of the surface of the buckle is only slightly changed, the entire buckle can only be remade, and it cannot be stocked as a general product in batches. It is easy to produce different types of snap buttons every time. Delays due to heavy workload

Embodiment 1

[0045] Embodiment 1: Reference Figure 1 to Figure 10 .

[0046] figure 1 It shows the snap button provided by the first preferred embodiment of the present invention, which includes a face button 1 and a positioning button 2 that are fastened to each other. The positioning button 2 can be configured as a male button with a convex column structure as required, or as a The female buckle with the groove structure is not specifically limited here.

[0047]In this embodiment, the face buckle 1 includes a detachable face shell 11 and positioning spikes 12, one end of the positioning spike 12 is connected with the face shell 11, and the other end passes through the base material 3 and is connected with the positioning buckle 2, so that the face The buckle 1 and the positioning buckle 2 are respectively clamped and fixed on the base material 3 from both sides. The base material 3 can be cloth, plastic, leather, artificial leather, non-woven fabric, etc., and is often used in the m...

Embodiment 2

[0071] Embodiment two: reference Figure 11 and Figure 12 .

[0072] The face shell 11 in this embodiment is made of plastic, which is different from the first embodiment in that the face shell 11 and the positioning feet 12 in this embodiment are pressed by hot pressing. Figure 11 and Figure 12 Assemble to obtain face buckle 1's.

[0073] When installing, insert the base 121 of the positioning spike 12 downwards into the installation chamber 111 and press it against the bottom of the installation chamber 111; then, use hot pressing to deform the fixed lip 112 by heat, and move it toward the shaft 122 is bent in the direction to completely cover the anti-rotation protrusion 125, and the inner surface of the fixed lip 112 is embedded around the anti-rotation protrusion 125 to engage the concave and convex, so that the fixed lip 112 is disc-shaped and pressed against the base of the positioning foot nail 12 121. The surface of the fixed lip 112 and the anti-rotation prot...

Embodiment 3

[0076] Embodiment three: reference Figure 13 and Figure 14 .

[0077] The difference between this embodiment and the previous embodiments is that the face shell 11 in this embodiment is directly molded on the outside of the positioning spike 12 by means of injection molding.

[0078] When assembling, the produced positioning spikes 12 are placed in the injection mold, and the face shell 11 is directly covered and fixed on the base 121 of the positioning spikes 12 through injection molding. The face shell 11 after injection molding completely covers the anti-rotation protrusion 125 and engages with it, thereby preventing the positioning feet 12 from shaking or rotating in the face shell 11; The chamber 111 is exposed to prevent the surface button 1 from sliding relative to the base material 3 .

[0079] Since the face shell 11 is molded directly to form a concavo-convex structure engaging with the positioning pin 12 , the fixed lip 112 for bending to cover the anti-rotatio...

Abstract

The invention discloses a snap fastener. The snap fastener comprises a face fastener and a locating fastener which are fastened with each other. The face fastener comprises a face shell and a locating pin, wherein the face shell is provided with an installation chamber and the locating pin is made of plastic and integrally formed. The locating pin comprises a base, a rod body and anti-rotation protrusions, wherein the base is contained in the installation chamber and anti-skidding structures are arranged on the end face, exposed out of the installation chamber, of the base; the rod body stands exactly on the end face of the base and the end, away from the base, of the rod body is used for being connected with the locating fastener; the anti-rotation protrusions are arranged on the outer edge of the end face, connected with the rod body, of the base in a protruding mode and the ends, away from the base, on the anti-rotation protrusions shrink. When the locating pin and the face shell are assembled, the anti-rotation protrusions are completely covered with the face shell and meshed with the face shell. By the adoption of the snap fastener, the face fastener can be divided into the face shell and the locating pin, the locating pin can be manufactured into a standard piece for batch production and storage so as to be suitable for the face shell with continuous updated design, delivery time is shortened, and cost is reduced.

Description

technical field [0001] The invention relates to the field of daily life, in particular to a snap button. Background technique [0002] The existing snap button structure includes a male button and a female button that are fastened to each other, wherein the base end surface of the male button is provided with a convex column extending vertically outwards with a concave edge, and the end surface of the female button is provided with a The groove is matched with the boss, and the groove is distributed with a lip at the opening. When in use, fix the male button and the female button on the sheets to be connected with through holes, and use the inherent elasticity of the snap button material to press the male button into the groove of the female button, and the convex lip snaps into place. Into the concave edge, the two connected bodies can be connected into one. [0003] In the current snap button structure, the face buckle used to connect with the male and female snaps mostl...
