Abstract
The utility model relates to a self-plugging rivet which comprises a core bar and a rivet sleeve sleeved outside the core bar of the rivet; the tail of the rivet sleeve is provided with a cap head used as a rivet cap; the head of the core bar is provided with a tightening section, the diameter of which is larger than that of the core bar and the internal diameter of the rivet sleeve; and the tail of the core bar penetrates the rivet sleeve from the head thereof. By adopting the structure, the riveting fastness is better. The self-plugging rivet is not only used for objects needing to be riveted with lower riveting strength, but also suitable for objects needing to be riveted with higher riveting strength.
Description
(1) technical field
The utility model relates to a kind of rivet, particularly a kind of self-plugging rivet.
(2) background technique
At present, existing rivet is of a great variety on the market, but present people have begun to use self-plugging rivet and have connected fastening, general self-plugging rivet comprises core bar and is set in the outer rivet cover of described rivet core bar, when the riveted joint thing was riveted, by the effect of riveting gun, the plush copper of core bar one end was drawn in the nail body, make the nail body not have nail Gai Yiduan and strut, thereby strut end and follow closely lid and will be clamped together by the riveted joint thing by this.Because core bar one end of this rivet only has plush copper, during riveted joint with the riveted joint thing between the riveted joint fastness not enough, can not be used for the riveted joint thing that the riveting intensity requirement is riveted than higher needs.
(3) summary of the invention
In order to overcome the poor deficiency of self-plugging rivet riveted joint fastness in the prior art, the utility model provides a kind of riveted joint fastness reasonable self-plugging rivet.
The technical scheme in the invention for solving the technical problem is: a kind of self-plugging rivet, comprise core bar and be set in the outer rivet cover of described core bar, the afterbody of described rivet cover is provided with the cap head as the nail lid, the head of described core bar is provided with fastening section, described fastening section diameter is greater than the diameter of described core bar, and described fastening section diameter is greater than the internal diameter of described rivet cover, and the afterbody of described core bar is penetrated by the head of described rivet cover.
Further, described core bar is provided with disconnected bar groove, and the afterbody of described core bar is provided with several grooves.
Further, described core bar is provided with disconnected bar groove, and the afterbody of described core bar is provided with screw thread.
Further, described core bar is provided with disconnected bar groove, and the afterbody of described core bar is provided with dimpled grain.
Further, be connected by a rounding stage body between the described fastening section main body with described core bar.
Adopt technique scheme, the head of described core bar is provided with fastening section, when riveting gun pulling core bar, the fastening section afterbody to the rivet cover moves, like this because fastening section diameter is bigger than the internal diameter of rivet cover, the head end that is the rivet cover expands, the fastening section head end with the rivet cover is close to, and after the riveted joint well, the riveted joint fastness is relatively good like this, be not only applicable on the riveted joint thing of the lower needs riveted joint of riveting intensity, be fit on the riveted joint thing of riveting intensity requirement than higher needs riveted joint yet.
The beneficial effects of the utility model are: adopt such structure, the head of described core bar is provided with fastening section, the riveted joint fastness is relatively good, is not only applicable on the riveted joint thing of the lower needs riveted joint of riveting intensity, also is fit on the riveted joint thing of riveting intensity requirement than higher needs riveted joint.

Fig. 1 is a self-plugging rivet overall structure schematic representation.
Fig. 2 is the core bar structure schematic representation.
Fig. 3 is a rivet nested structure schematic representation.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of self-plugging rivet, comprise core bar 1 and be set in described core bar 1 outer rivet and overlap 2, the afterbody of described rivet cover 2 is provided with the cap head 3 as the nail lid, the head of described core bar 1 is provided with fastening section 4, described fastening section 4 diameter is greater than the diameter of described core bar 1, and described fastening section 4 diameter is greater than the internal diameter of described rivet cover 2, and the afterbody of described core bar 1 is penetrated by the head of described rivet cover 2.In the present embodiment, described core bar 1 is provided with disconnected bar groove 5, and the afterbody of described core bar 1 is provided with several grooves 6.Be provided with disconnected bar groove 5, after riveting gun is riveted self-plugging rivet, the core bar 1 that stretches out cap head 3 can be fractureed core bar 1 more easily by disconnected bar groove 5 places.Several grooves 6 of core bar 1 afterbody can allow more easily riveting gun can fix catches core bar 1.Certainly several grooves 6 not necessarily can also be screw threads, or dimpled grain, can also be other arbitrary structures that are fit to.Be connected 7 by a rounding stage body between described fastening section 4 main body with described core bar 1.Being connected with rounding platform 7 can allow the fastening section 4 more or less freely rivet that is drawn into overlap in 2.
Adopt above-mentioned structure, the riveted joint fastness is relatively good, is not only applicable on the riveted joint thing of the lower needs riveted joint of riveting intensity, also is fit on the riveted joint thing of riveting intensity requirement than higher needs riveted joint.
