Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 3, the present invention mainly comprises rivet nut 1 and blind rivet 2, and rivet nut 1 is tubular structure, and rivet nut 1 is provided with oblate rivet nut 3 towards blind rivet 2 one end, and the diameter of rivet nut 3 is greater than the diameter of rivet nut 1.
Be provided with rivet nut center hole 4 along rivet nut 1 axial direction in rivet nut 1, rivet nut 3 center are provided with ailhead hole 7, and ailhead hole 7 is communicated with rivet nut center hole 4.The diameter in described ailhead hole 7 is greater than the diameter of rivet nut center hole 4, and the setting in ailhead hole 7 produces burr after the first riveted joint plate body A and second riveted joint plate body B riveted joint.
In order to when riveting easily and effectively position, the external peripheral surface of rivet nut 1 is provided with two rivet nut opening slots 5 distributed symmetrically, two rivet nut opening slots are provided with opening slot kink 6 near rivet nut 3 side, opening slot kink 6 is communicated with rivet nut opening slot 5, and the area of opening slot kink 6 is greater than the area of rivet nut opening slot 5.
Be provided with blind rivet 2 in rivet nut 1, blind rivet 2 is solid body structure, and blind rivet 2 is provided with oblate blind rivet 8 towards rivet nut 1 one end, and the diameter of blind rivet 8 is greater than the diameter of blind rivet 2.Blind rivet 2 is provided with draw ring 11 in rivet nut 1 one end dorsad, and the diameter of draw ring 11 is greater than the diameter of blind rivet 2.The oblate structure of blind rivet 8, can have good profile after riveted joint completes, and especially surface can be smooth, there will not be the situations such as burr.The diameter of rivet nut 3 is greater than the diameter of rivet nut 1, and the diameter of blind rivet 8 is greater than the diameter of blind rivet 2, can ensure that, when riveting, blind rivet 2 and rivet nut 1 can obtain good location.
Blind rivet 2 is provided with cone fracture portion 9 near blind rivet 8 one end, blind rivet 2 is provided with blind rivet joint 10 near draw ring 11 one end.The center of described blind rivet 8, cone fracture portion 9, blind rivet joint 10 and draw ring 11 all on the same axis.
Described blind rivet 2 stretches in rivet nut center hole 4 and ailhead hole 7, and blind rivet 8 is stretched out the rivet nut center hole 4 of blind rivet 2 and formed front end with blind rivet 2 end face and locate, and draw ring 11 and blind rivet 2 tail end stretch out ailhead hole 7.
As shown in Fig. 4 ~ 6, during riveted joint, rivet plate body A and second riveted joint plate body B at two boards shape body first to be riveted and beat riveted holes, the end by rivet nut of this product is inserted together two boards shape body first and rivet in the hole of plate body A and second riveted joint plate body B.Pull draw ring, under the effect of pulling force, the opening slot kink of blind rivet head compressing rivet nut, making to be positioned at the outer soldier of the opening slot kink near riveted plating of riveted holes first bending drives opening slot to be bent into cydariform together, tightly two riveted platings first are riveted plate body A and second riveted joint plate body B riveted joint firmly, the cone fracture portion of blind rivet is at ailhead hole Fracture, and riveted joint terminates.Because cone fracture portion is that conical structure is arranged, after having riveted, the cone fracture portion in blind rivet is bumped in rivet nut, and formed and fall structure, thus guarantee the present invention and first rivet plate body A and second rivet to rivet between plate body B two pieces firm, never becoming loose, state after riveted joint, as shown in Figure 6.The present invention rivets easy, need not any Riveting Tool, easily completes connection, is the essential product at home under travelling, particularity condition in fact, energy-conserving and environment-protective.
