Description
Technical field
The utility model relates to a kind of fastening piece, specifically a kind of pulling rivet.
Background technique
The installation of existing most of material generally uses bolt to be fixedly connected with, and the bolt that this Placement is deposited after mounting protrudes surface, easily scratches goods, and bolt connects the hidden danger existing and loosen.
Model utility content
The purpose of this utility model is to provide a kind of pulling rivet, this rivet spiral chute and collar squeezed riveting, the mechanical interlock mechanism of formation, and shock-proof check is remarkably productive, and the pressure born by riveting parts is little.
The technical scheme in the invention for solving the technical problem is: a kind of pulling rivet, its structure comprises rivet and the collar, described rivet is made up of ailhead and nail bar, the described collar is made up of flange and sleeve, the arc groove of depression is provided with inside described ailhead, described nail bar is provided with spiral chute, separating vessel and tail tooth section, the pawl lobe clamping in the nail tail tooth section of bar and riveting machine.
Further, described collar endoporus is shoulder hole, and wherein hub internal bore diameter is greater than spiral fluted external diameter, and flange diameter of bore is less than spiral fluted external diameter.
Further, described flange is plane face flange or sink flange.
Further, the nail bar free end of described rivet passes the riveted holes of the first link and the second link successively, the collar is inserted in from the free end of nail bar, and the tail tooth section of described nail bar is inserted in riveting machine pawl lobe, the nail bar of pulling rivet after riveting machine pawl lobe, the riveting gun of riveting machine will be pushed in riveted holes before the collar, the endoporus of sleeve is along the distortion of ailhead arc groove, and rivet continues post-tensioning, and nail bar ruptures at separating vessel place, riveting machine retreats, and riveted joint completes.
The beneficial effects of the utility model are:
1, rivet of the present utility model is by the spiral chute on nail bar and collar squeezed riveting, and the mechanical interlock mechanism of formation, shock-proof check is remarkably productive.
2, because the cover ring flange of design belongs to large flange design and spiral fluted structure, have impacting force little, the pressure born by riveting parts is little, is only had 1/3 of common pulling rivet after riveted joint by the pressure that riveting parts bears.
3, this rivet rear surface is without protrusion, both artistic and practical.

Embodiment
With reference to Figure of description, a kind of pulling rivet of the present utility model is described in detail below.
As Figure 1 and Figure 4, a kind of pulling rivet of the present utility model, its structure comprises rivet 1 and the collar 2, described rivet 1 is made up of ailhead 11 and nail bar 12, the described collar 2 is made up of flange 21 and sleeve 22, be provided with the arc groove 111 of depression inside described ailhead 11, described nail bar 12 is provided with spiral chute 121, separating vessel 122 and tail tooth section 123, pawl lobe 51 clamping in the nail tail tooth section of bar 12 and riveting machine 5.Riveting machine 5 is made up of pawl lobe 51 and riveting gun 52.
The described collar 2 endoporus is shoulder hole, and its middle sleeve 22 diameter of bore is greater than spiral fluted external diameter, and flange diameter of bore is less than spiral fluted external diameter.Hub internal bore is inserted in the arc groove extrusion-deformation by ailhead place after in spiral chute.During riveted joint, hub internal bore one end and spiral chute extrude and lock, and the other end along the plastic deformation of ailhead arc groove, thus can reach riveting quality requirement.Wherein following closely pole length can according to the Thickness of riveting parts, and the value of supporting corresponding collar overall length.
As shown in Figure 2, described flange is plane face flange 211, and as shown in Figure 3, flange also can adopt sink flange 212, adapts to different riveted joint requirements, flexible and convenient to use.
As shown in Figure 4, nail bar 12 free end of described rivet passes the riveted holes 31 of the first link 3 and the second link 4 successively, and the collar is inserted in from the free end of nail bar, the tail tooth section of described nail bar is inserted in riveting machine pawl lobe, as shown in Figure 5, the nail bar of pulling rivet after riveting machine pawl lobe, the riveting gun of riveting machine will be pushed in riveted holes before the collar, the endoporus of sleeve is out of shape along ailhead arc groove, as shown in Figure 6, rivet continues post-tensioning, and nail bar ruptures at separating vessel place, riveting machine retreats, and riveted joint completes.
Rivet of the present utility model is by the spiral chute on nail bar and collar squeezed riveting, and the mechanical interlock mechanism of formation, shock-proof check is remarkably productive.Cover ring flange because of design belongs to large flange design and spiral fluted structure, and have impacting force little, the pressure born by riveting parts is little, is only had 1/3 of common pulling rivet after riveted joint by the pressure that riveting parts bears.
The above, just explain through diagrams principles more of the present utility model, this specification is not the utility model to be confined in shown described concrete structure and Applicable scope, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
Except technical characteristics described in specification, all the other technical characteristicss are those skilled in the art's known technology.
