Abstract
The utility model relates to a single-side riveting pull rivet, pertaining to a novel cold drawn rivet, which consists of a rivet head, a main bar, a pull bar, a separating groove, a rivet bar arranged outside the main-ring groove section and a casing ring sleeved outside the rivet bar; the rivet head and the outer diameter of the front casing ring are all less than the diameter of the holes of two objects which are connected with the rivet, thus realizing to insert single-side pull rivet from one side space . The casing of the casing ring consists of a front casing ring of thin-wall deep-drum type outside the main bar and a post casing ring with a large outer diameter; when riveting, the casing ring can yield and deform into a fastened stable state, so as to ensure to smoothly finish the riveting process; the internal diameter of the casing ring and the outer diameter of the rivet bar employ interference fit, guaranteeing the rivet bar and the casing ring not to fall off. The patent provides 7 optimized casing ring sizes matching with 7 rivet bar specifications, and the patent has been theoretically and practically tested, so as to enable the riveted objects to be tightly connected. The utility model can be broadly used in the situation that the space of the objects to be riveted is limited at one side.
