Detailed description of the invention
Below by combining accompanying drawing, the invention is further described.
The invention structure one embodiment as shown in figures 1 to 6, including:
Core bar 1, one end is provided with afterbody convex body 11, and middle part is provided with cut-off neck slot 12；
Lining 2, is set on described core bar 1, the afterbody convex body 11 of one end (can be considered tail end) and described core bar 1
Contact is the most spacing by described afterbody convex body 11, and the other end (can be considered head end) extends to make institute to the middle part of described core bar 1
Stating cut-off neck slot 12, to be positioned at described lining 2 internal, described lining 2 be positioned at the end of one end (head end) in the middle part of described core bar 1
Locking hole 21 is inwardly offered on face；
Lock ring 3, adjacent with described lining 2 is set on described core bar 1, and described locking is goed deep in one end of described lock ring 3
In hole 21 and spacing by the inwall constituting described locking hole 21；
Rubber sleeve 4, outside being coated on the afterbody convex body 11 of described core bar 1 continuously and at least one of lining 2 periphery
Point.
Wherein, described rubber sleeve 4 uses macromolecular material to make, and has good elasticity and decay resistance, it is possible to
Effective sealing corrosion effect is played after installation.
Wherein, described locking hole 21 is round table-like in successively decrease from the inside internal diameter of end face, beneficially lock ring 3 spacing fixing and
During installation, lock ring 3 deforms into.
Wherein, described lining 2 be positioned at that the one end in the middle part of described core bar 1 has that outer end face the most without leave inwardly successively decreases round table-like
Head 22, described locking hole 21 is positioned at described head 22.
Wherein, the set body 23 except described head 22 of described lining 2 includes middle part set body 231 and afterbody set body
232, described rubber sleeve 4 is coated on outside described afterbody set body 232, and the thickness of described middle part set body 231 is more than
The thickness of described afterbody set body 232, on the one hand, thicker described middle part set body 231 is normally at when mounted to be treated
Inside installing hole, can play good supporting role, on the other hand, relatively thin described afterbody set body 232 is being installed
Shi Suitong rubber sleeve 4 is easy to deform upon together, forms bulge, plays fastening and sealing function.Preferably, in described
The external diameter of portion's set body 231 is equal with the external diameter of described rubber sleeve 4.
Wherein, on described core bar 1, between described afterbody convex body 11 and described cut-off neck slot 12, it is additionally provided with locking slot 13,
Described locking slot 13 has inside closing in, it is possible to coordinate composition to have with the locking hole 21 of described lining 2 round table-like logical
The wedge shape space in road, it is simple to during installation, lock ring 3 deforms into this wedge shape space.Preferably, described locking slot 13 and institute
State cut-off neck slot 12 close or adjacent.
Wherein, on described core bar 1, one end relative with described afterbody convex body 11 is additionally provided with the clamping for gripping
Mechanism 14, described clamping device 14 can be some scrobicular rings as depicted, it is also possible to for screw thread or symmetrically arranged twisting
The structures such as face.
Wherein, the self-plugging rivet of the present invention is also further provided with pushing lining 5, adjacent with described lock ring 3 is set in described core
On bar 1, contacting with each other with the end face of described lining 2 with the end face of one end of described lock ring 3 homonymy, described pushing serves as a contrast
It is additionally provided with the concave station 53 that the part do not goed deep in described locking hole 21 with described lock ring 3 matches, described pushing in set 5
It is spaced by thin ring 54 of cutting between sleeve body portion 51 and the set portion 52 constituting described concave station 53 of lining 5.Enter one
Step, has pushing closing in 511 in the middle part of described pushing lining 5, sleeve body portion 51 is pushed closing in 511 and set head by described
512 compositions, described pushing closing in 511 are divided to be easy to when mounted apply or transmitting forces to lock ring 3, described set head
Divide 512 to have bigger external diameter, be easy to external tools (such as riveting gun) when mounted and apply active force to it.
The brief work process of the invention is, the invention has been assembled according to suit mode as shown in Figure 1
After, insert in the riveted holes of parts to be riveted, make the head 22 of lining 2 push against the riveted holes aperture of parts to be riveted.Make
With auxiliary implement, such as riveting gun, gripping the clamping device 14 of core bar 1, the chuck end face of riveting gun pushes against pushing lining 5
Head segment 512, later on riveting gun is started working.Riveting gun clamping core bar 1 pushes lining 5 relatively to clamping device
The direction motion of 14, the power that the chuck end face of riveting applies passes to lining 2 by pushing lining 5, and lining 2 is pushing
Under squeezing action between the afterbody convex body 11 of lining 5 and core bar 1, there is deformation of cylindrical in position at weak step,
Afterbody set body 232 deforms together with being coated on rubber sleeve 4 thereon, and rubber sleeve 4 is tightly pressed by the deformation bulge of formation
Tightly installing matrix surface, rubber sleeve 4 is therefore, it is possible to by after the liquid (such as fluid etc.) of components interior to be riveted and installation
Self-plugging rivet metal matrix material isolation come, play the effect of sealing corrosion.After bulge finally shapes, core bar 1 nothing
Method continues motion, and now locking slot 13 coordinates composition to have the wedge shape of round table-like passage with the locking hole 21 of described lining 2
Space, riveting gun pulls on and can will push against lining 5 and cut off from the position cutting ring 54, pushes the set body of lining 5 after cutting off
Divide 51 promotion lock rings 3 to move to wedge shape space, and final crimp is completely into wedge shape space.Pulling force on core bar 1
During continuing to increase, when exceeding the force value that the cut-off neck slot 12 of core bar 1 can bear, core bar 1 will rupture from cut-off neck slot 12,
After fracture, nubbin separates with the riveting portion entering riveted holes aperture, thus completes to rivet locking process (Fig. 7).
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all at this
Within the spirit of bright creation and principle, any modification, equivalent substitution and improvement etc. made, should be included in present invention wound
Within the protection domain made.
