Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Among Fig. 1～Fig. 5, comprise nail body 1, nail core 2, kink 3, nail body body 4, nail body head 5, hollow hole 6, nail core head 7, groove 8, fracture portion 9, nail core bar 10, first tabular body 11, second tabular body 12 etc.
As shown in Figure 1, the utility model is a kind of step self-plugging rivet, comprises nail body 1 and inserts the nail core of following closely in the body 12.
As shown in Figure 2, nail body 1 comprises the tubular pin body body 4 with hollow hole 6.One end of nail body body 4 is provided with the nail body head 5 of external diameter greater than nail body body 4 external diameters, and nail body head 5 provides a good location for when riveted joint nail body 1.5 one-tenth sphericals of nail body head, this spherical is good-looking after riveted joint is finished, and especially meeting smoother in surface burr etc. can not occur.The other end of nail body body 4 is provided with the kink 3 of external diameter less than nail body body 4 external diameters.
Form step between kink 3 and the nail body body 4.The outer end of nail body body 4 is provided with fillet.Kink 3 also is provided with fillet with the joint of nail body body 4.
As shown in Figure 3, nail core 2 comprises solid nail core bar 10.One end of nail core bar 10 is provided with the nail core head 7 of external diameter greater than nail core bar 10 external diameters, and nail core head 7 provides a good location for when riveted joint nail core 2.7 one-tenth sphericals of nail core head, the same with nail body head 5, this spherical is good-looking after riveted joint is finished, and especially meeting smoother in surface burr etc. can not occur.Nail core head 7 is positioned at kink 3 one ends of nail body 1, and the diameter of nail core head 7 equates that with the external diameter of kink 3 nail core bar 10 is inserted in the hollow hole 6.Nail core bar 10 is provided with the fracture portion 9 that cross sectional area diminishes, and the nail core bar 10 between fracture portion 9 and the nail core head 7 is provided with annular groove 8, and the external diameter of groove 8 is less than the external diameter of nail core bar 10.Groove 8 is provided with two or more.
