Abstract
Disclosed is a snap fastener, comprising a face fastener (1) and a locating fastener (2) which are snapped with each other, wherein the face fastener (1) comprises a face shell (11) provided with an installation chamber (111), and a locating pin (12) made of plastic and integrally formed; and the locating pin (12) comprises a base (121), a rod body (122) and anti-rotation protrusions (125). In the implementation of the snap fastener of the present invention, the face fastener (1) can be separated into the face shell (11) and the locating pin (12), and the locating pin (12) is manufactured into a standard part for batch production and storage, thereby adapting face shells (11) with continuously updated designs, shortening delivery time, and reducing costs.
Claims6
A snap fastener comprising a face fastener (1) and a locating fastener (2) which are snapped with each other, wherein, the face fastener (1) comprises:
- a face shell (11), wherein the face shell (11) is provided with an installation chamber (111);
- and a locating pin (12);
- and the locating pin (12) is made of plastic and integrally formed, and includes:
- a base (121), wherein the base (121) is accommodated in the installation chamber (111);
- and anti-skidding structures (124) are arranged on an end face exposed out of the installation chamber (111) of the base (121);
- a rod body (122), wherein the rod body (122) stands exactly on an end face of the base (121), and an end away from the base (121) of the rod body (122) is used to be connected to the locating fastener (2);
- and anti-rotation protrusions (125), wherein the anti-rotation protrusions (125) are arranged at an outer edge of the end face in connection with the rod body (122) of the base (121) in a protruding manner, and ends away from the base (121) of the anti-rotation protrusions (125) shrink;
- and when the base (121) is accommodated in the installation chamber (111), so that the locating pin (12) and the face shell (11) are assembled;
- a fixing flange (112) is formed at an edge of an opening around the installation chamber (111) in an end face of the face shell (11), so that when the locating pin (12) and the face shell (11) are assembled, the face shell (11) completely covers the anti-rotation protrusions (125) and is meshed therewith;
- when the locating pin (12) and the face shell (11) are assembled, the fixing flange (112) is bent by way of riveting, heat-pressing or cold-pressing to completely cover the anti-rotation protrusions (125) and be meshed therewith;
- and inner surfaces of the fixing flange (112) are respectively arranged around the anti-rotation protrusions (125) to form concavo-convex occlusion.
