Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention 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 present invention 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.
Above-mentioned fracture portion 9 is for being arranged on the wedge-shaped indentation on the nail core bar 10.Wedge-shaped indentation preferably is provided with two, is symmetrical arranged.The cross sectional area of fracture portion 9 is less than the cross sectional area of nail core bar 10, and in when riveted joint, the fracture location that can guarantee to follow closely core 2 is just at the position at fracture portion 9 places.
As Fig. 4, shown in Figure 5, when using the present invention to rivet, punching on first tabular body 11 to be riveted and second tabular body 12, punching size on first tabular body 11 is complementary with kink 3 external diameters of nail body 1, and the punching size on second tabular body 12 is complementary with nail body body 4 external diameters of nail body 1.The nail core bar 10 of nail core 2 is followed closely in the hollow hole 6 of body 1 from the kink 3 one ends insertion of nail body 1, and make the nail core head 7 of following closely core 2 be adjacent to the end face of kink 3, will follow closely core head 7 then and insert in the hole of two boards shape body 12,11 from second tabular body, 12 1 sides together with nail body 1.Nail core 2 is under the effect of riveting gun, and the kink 3 of nail core head 7 compressing nail bodies 1 makes kink 3 expanded drums become drum type, and is crooked nail core 2 and 1 compressing of nail body, firmly the step place of first tabular body 11 between kink 3 and nail body body 4 is pinned.And second tabular body 12 is free to rotate owing to the length of its thickness less than nail body body 4.And the end of kink 3 is against two connecting parts with upper groove 8 and nail core head 7 of following closely compacting on the core 2 tightly when being extruded distortion, nail core head 7 is not come off, and guarantees to rivet firmly never becoming loose with first tabular body 11.
The present invention's nail body is provided with the kink of large diameter nail body body and minor diameter, form step between two-part, rivet firmly owing to pressing close to step by half workpiece of kink the riveted joint back, and second half workpiece is owing to press close to follow closely the body head, its thickness is during less than the length of nail body body, can be free movable or freely rotate, be specially adapted to the connection of small electric apparatus, toy and pulley etc.When using the present invention to connect, can keep riveted joint on the one hand firmly, free to rotate on the one hand, adapt to special connection request, the present invention is simple to operate, and noise is low.
