External member 2 is in substantially circular ring shape, is used to be riveted part 4 and is connected to rivet, is riveted part 4 and mother to realize
The connection of material 3, external member 2 can prevent from being riveted part 4 to fall off from rivet.In the present invention, rivet passes through rivet head 11
It is welded in base material 3, part 4 is riveted and is set in nail rod portion 13 and by 2 contact of external member in tension portion 12.Rivet is welded in base material
When 3, the fusing of rivet head 11 is in holding tank 121, and tension portion 12 is abutted with base material 3；It is supported being riveted part 4 by external member 2
It is connected in the state of tension portion 12, nail rod portion 13 is fractureed by the end of annular groove 131 from external member 2.
Part 4, which will be riveted, by the rivet of the utility model is connected on base material 3 that detailed process is as follows:
Firstly, rivet ontology 1 to be welded on to the surface of base material 3 using arc welder, in the present invention, base material 3 can
For plate or square tube, the material that can be welded is used to be made.As shown in figure 4, after rivet head 11 is welded by arc welder,
It melts and is filled in holding tank 121, and form fusion welding region 15.The surface in fusion welding region 15 just with tension portion
12 flush so that the holding tank 121 in tension portion 12 is completely filled, and is bonded with the surface of base material 3, is realized solid
Fixed connection.In the present embodiment, the outside diameter d 3 in fusion welding region 15 is greater than the outside diameter d of rivet head 11, and is slightly less than receiving
The outside diameter d 1 of slot 121.
Later, it is successively covered from the free end in nail rod portion 13 and is riveted part 4 and external member 2.In the present invention, it is riveted
The material of part 4 can be identical or different with the material of rivet ontology 1 and base material 3.Before riveting, external member 2 and nail rod portion 13 are gap
Cooperation.When riveting, nail rod portion 13 is connected with hand riveter, and under the unidirectional pulling force effect of hand riveter, external member 2 is deformed and embedding
It closes in multiple annular grooves 131 in nail rod portion 13, is engaged so that external member 2 is formed with nail rod portion 13, generates permanent fastening force.Nail rod
The annular groove 131 of external member 2 and hand riveter junction in portion 13 generates necking deformation until fracture, open position under a stretching force
It is concordant with the end of external member 2, riveting is completed, as shown in Figure 5.Riveting process only needs 5~6 seconds, easy to operate, and connects reliable.
In a specific embodiment of the utility model, as shown in figures 1 and 3, with the nail rod portion 13 of rivet ontology 1
Outside diameter d=4.8mm is illustrated for length L=60mm.Certainly, in other examples, the outside diameter d in nail rod portion 13 and
Length L is without being limited thereto.As the outside diameter d=4.8mm in nail rod portion 13, the outer diameter of rivet head 11 and the outer diameter in polished rod portion 14 are
4.8mm, the outside diameter d 1=6mm of the holding tank 121 in tension portion 12, the groove depth L1=0.65mm of holding tank 121, the thickness in tension portion 12
Spend L2=2mm, the outside diameter d 2=9.5mm in tension portion 12, the thickness L3=1mm in polished rod portion 14, the width z=of annular groove 131
0.2mm, opening angle β=74 ° of annular groove 131, two-by-two the interval z1=0.2mm between adjacent annular groove 131.
The fracture position of the rivet of the utility model, nail rod portion 13 can be adjusted according to the thickness for being riveted part 4, and with
Matched external member 2 is concordant.The rivet of the utility model is easy to weld the welding, it can be achieved that high-intensitive, and can effectively improve welding
The flatness on base material surface afterwards.Simultaneously when riveting, riveting operation is not limited by the thickness for being riveted part 4, can be realized high quality,
High-intensitive riveting.After connection, ailhead is not revealed on 3 surface of base material, and smooth beauty is fixed well, easy to operate, low noise, connection
Reliably, especially suitable for the connection structure in the higher related fields of surface requirements, as aerospace field, military industry field,
Special dimensions such as rail traffic etc..In addition, the rivet of the utility model compares traditional rivet, then no longer need in riveting process to mother
The operation such as is punched, is polished in the outer surface of material 3, easy to operate, high-efficient；Compared to tradition weldering nail, without it is additional increase nut,
Spring washer etc. realizes the loss of weight requirement of structure, and high reliablity.Therefore there is the unrivaled advantage of conventional coupling arrangement.
The foregoing is merely several embodiments of the utility model, and those skilled in the art is according to disclosed in application documents
Content can carry out various changes or modifications without departing from the spirit and scope of the utility model to the utility model embodiment.
