Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment：
A kind of combined rivet, as Figure 1-3, including tubular rivet 1 and solid rivet 2, by by tubular rivet 1 and in fact
Heart rivet 2 is arranged in the mounting hole on two parts, so as to which two parts be interconnected and fixed.
As shown in figure 1, tubular rivet 1 and solid rivet 2 are that stainless steel material is made, offered on tubular rivet 1
For wearing the through hole 3 of solid rivet 2.4 grooves 4 are offered in the top and bottom of tubular rivet 1, groove 4 is around hollow
The center of circle circumference array of rivet 1 is set, and the top and bottom of tubular rivet 1 can be bent with stress.And in the outside of tubular rivet 1
It is connected with integrally formed fastening block 5, the internal diameter of the external diameter of fastening block 5 and the mounting hole of installing component is equal so that hollow riveting
After nail 1 is attached in mounting hole, tubular rivet 1 can not move radially, and avoid causing riveting not because tubular rivet 1 moves radially
Firmly.
As shown in Fig. 2 space 14 between the top and bottom of tubular rivet 1 and the inwall of mounting hole be present, when hollow riveting
When following closely the bending of 1 stress, the space 14 between tubular rivet 1 and mounting hole can cause the top and bottom of tubular rivet 1 curved
When bent will not excessive compression part, avoid the mounting hole of part from being squeezed and become it is big cause to connect it is insecure.
As shown in Figure 1, 2, the opening position in the corresponding top and bottom of tubular rivet 1 of solid rivet 2, which is connected with, is integrally formed
Abutting block 6, abut block 6 size be slightly larger than the through hole 3 of tubular rivet 1 diameter so that when solid rivet 2 is caught in tubular rivet
When in 1, the top and bottom of the meeting extruded hollow of block 6 rivet 1 are abutted so that the top and bottom of tubular rivet 1 are abutted
The extruding of block 6 and bend.
As shown in Figure 1, 2, integrally formed projection 7 is connected with the bottom outside of tubular rivet 1, is provided with projection 7
Chamfering 8, by chamfering 8, when tubular rivet 1 is caught in mounting hole, the inwall of mounting hole abuts chamfering 8, convex so as to extrude
Block 7 so that tubular rivet 1 curves inwardly, convenient to install tubular rivet 1 in mounting hole, and when solid rivet 2 is caught in through hole
After in 3, the extruded hollow rivet 1 of block 6 is abutted so that the top and bottom meeting stress bending of tubular rivet 1, projection 7 is upon bending
It can be abutted with the side wall of part, coordinate with the head of a nail of tubular rivet 1, two parts are interfixed；The head of a nail of solid rivet 2 is set
There is the groove 13 for accommodating projection 7.Inclined-plane 9 is provided with block 6 is abutted, solid rivet 2 is caught in sky by the way that inclined-plane 9 is convenient
In heart rivet 1.
As shown in Figure 1, 2, integrally formed swash plate 10, the one end of swash plate 10 away from fastening block 5 are connected with fastening block 5
Abutted with the inwall of mounting hole, for increasing the frictional force of tubular rivet 1 and part, and one is connected with solid rivet 2
The stripper plate 11 of shaping, and stripper plate 11, when solid rivet 2 is being caught in tubular rivet 1, will can squeeze to be obliquely installed
Pressing plate 11 moves inward along groove 4, and abuts block 6 due to being connected with solid rivet 2 so that solid rivet 2 and hollow riveting
Gap be present between nail 1, stripper plate 11 is squeezed bending in moving process so that from solid rivet 2 and tubular rivet 1 it
Between gap by the way that after the installation of solid rivet 2, stripper plate 11 can be connected on swash plate 10, and solid rivet 2 is pulled outwardly
It is dynamic, the bending extruding swash plate 10 of stripper plate 11 so that solid rivet 2 can not move.
As shown in Figure 1, 2, multiple fixed blocks 12 are provided with the outside of the both ends of tubular rivet 1, when solid rivet 2 is caught in sky
After in heart rivet 1, the meeting deformation bending of tubular rivet 1, so that fixed block 12 abuts with the inner wall of the hole installing of part, increase is empty
Frictional force between heart rivet 1 and part.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, it is all in this practicality
Within new design concept, any modification, equivalent substitution and improvements made etc., protection of the present utility model should be included in
