[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] like Figs. 1-3 As shown, the snap fastener with a side-sliding positioning structure proposed in this utility model includes a male panel 100, a female panel 200, a positioning spring 300, and a positioning wing 210. The male panel is made of stamped metal sheet, with one side protruding outward along the axial direction to form a insertion post 120. The end of the insertion post has an enlarged end 121 with a gradually expanding diameter. The female panel is also made of stamped metal sheet, and has an obstruction opening 220 and a limiting opening 230 inside. The limiting opening and the obstruction opening are arranged radially along the female panel and are interconnected. The diameter of the obstruction opening is larger than the diameter of the enlarged end, and the diameter of the limiting opening is smaller than the diameter of the enlarged end but larger than the diameter of the insertion post. The enlarged end can be inserted into the obstruction opening and then slide towards the limiting opening. The limiting opening axially positions the enlarged end and the insertion post. The positioning spring is made of bent metal wire. The folded shape extends along the edges of the clearance and limiting openings, with an opening near the limiting opening to allow for switching between open and closed states. A pair of clamping flanges 310 are located inside the positioning spring, positioned on both sides of the limiting opening and at the junction of the limiting and clearance openings. These flanges protrude inwards from the limiting opening. Each clamping flange has a tapered structure, and the distance between them is less than the diameter of the insertion pipe post. When the expanded end extends into the clearance opening and slides towards the limiting opening, the insertion pipe post can push the clamping flanges apart to both sides. After sliding into position, the clamping flanges return to their original position, thus radially limiting the expanded end and the insertion pipe post in the limiting opening. A pair of positioning wings are provided, each formed on the edges of the clearance opening. They fold axially towards the inner side of the mother panel and abut against the side wall of the positioning spring, thus positioning the positioning spring.

[0027] In this embodiment, the snap fastener also includes a female back plate 400, which is located behind the female panel and is formed by stamping metal sheet. Its edge is bent forward and abuts against the back of the female panel. The edge of the female panel is bent backward and wraps around the edge of the female back plate, so that the female back plate and the female panel are connected to each other.

[0028] In this embodiment, an identification notch 410 is provided on the edge of the mother panel. The identification notch corresponds to the position of the limiting port. The orientation of the limiting port can be identified through the identification notch, so as to facilitate the accurate installation of the mother panel and the mother back plate.

[0029] In this embodiment, the snap fastener also includes a female connector plate 500, which is located behind the female back plate and is formed by stamping metal sheet. Its middle part extends outward along the axial direction to form a female connecting tube 510. The female connecting tube passes through the female back plate and extends to the front of the female back plate. Its end is rolled outward to expand the diameter, so that the female connector plate and the female back plate are fixedly connected, and the fabric is sandwiched between the female connector plate and the female back plate.

[0030] In this embodiment, the snap fastener also includes a male connector plate 600, which is located behind the male connector panel. It is formed by stamping a metal sheet, with its middle part extending axially towards the front of the male connector plate to form a male connector connecting tube 610. The male connector connecting tube extends from the rear into the insertion tube and the enlarged end, and its end collapses and expands to fix the male connector plate and the male connector panel together, thus clamping the fabric between the male connector plate and the male connector panel.

[0031] In this embodiment, the edge of the female connector plate is rolled forward to form a female connector flange 520. A female connector mating annular groove is formed between the female connector flange and the female connector post. The middle part of the female back plate protrudes backward to form a female connector mating boss 410. The female connector mating boss is embedded in the female connector mating annular groove to assist in the positioning of the connection between the female connector plate and the female back plate.

[0032] In this embodiment, the male part panel is provided with a male part mating concave ring 110, which is located on the rear side of the male part panel. The male part connecting plate is provided with a male part mating convex ring 620, which protrudes forward toward the front of the male part back plate and is embedded in the male part mating concave ring, thereby assisting in the positioning of the connection between the male part connecting plate and the workpiece panel.
