Embodiment
Below in conjunction with accompanying drawing and the technical scheme of the present invention is described further by embodiment.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of two ailhead step self-plugging rivet comprises rivet nut 1 and blind rivet 2, described rivet nut 1 comprises the tubulose rivet nut body 4 with hollow hole 3, described blind rivet 2 comprises solid blind rivet bar 5, described blind rivet bar 5 is inserted in the hollow hole 3 of described rivet nut body 4, one end of described rivet nut body 4 is provided with the first rivet nut head 6 that external diameter is greater than described rivet nut body 4 external diameter, described first rivet nut head 6 is oblate shape, and it provides a good location when riveting to rivet nut 1. And described first rivet nut head 6 arranges, relative to the other end arranging rivet nut body 4, the stage portion 7 that external diameter is less than the first ailhead head, the external diameter of described stage portion 7 is equal with the external diameter size of described rivet nut body 4, and described stage portion 7 connecting external diameter is greater than the 2nd rivet nut head 8 of described stage portion 7; Described 2nd rivet nut head 8 is spherical in shape, is designed to spherical relatively more firm after riveted joint completes, and especially surface meeting smoother, there will not be burr etc., be conducive to the connection of another workpiece.
Described blind rivet bar 5 afterwards and stretches out through described rivet nut body 4, first rivet nut head 6, stage portion 7 and the 2nd rivet nut head 8 successively, one end of described blind rivet bar 5 is provided with the blind rivet head 9 that external diameter is greater than described blind rivet bar 5 external diameter, described blind rivet head 9 is positioned at one end of described rivet nut body 4, and described blind rivet head 9 is that its diameter semicircle is equal with the external diameter of described rivet nut body 4, described blind rivet head 9 is designed to semicircle good-looking after riveted joint completes, especially surface meeting smoother, there will not be burr etc.
