Therefore, design one can realize two-sided riveted joint, and riveted joint is firm, is difficult for becoming flexible, and the part that presses that can be widely used in the fastening fields such as various vehicles, boats and ships, aviation, building, bridge is a problem of needing solution badly.
Model utility content
The defect existing for prior art, the utility model provides a kind of ring groove shape rivet, and it can realize two-sided riveted joint, and riveted joint is firm, is difficult for becoming flexible, and can be widely used in the fastening fields such as various vehicles, boats and ships, aviation, building, bridge.
The technical solution of the utility model is:
A kind of ring groove shape rivet, the rivet bar that comprises round end and be connected with round end, the entirety that described round end and rivet bar are formed in one, it is characterized in that: also comprise riveting cover, described rivet bar is divided into bar head, in bar and bar tail, the cylindrical bar head that described rivet bar and round end joint are smooth in appearance, away from one end of round end, it is bar tail, in bar between bar head and bar tail, in described bar and between bar head, be provided with annular locking groove, in described bar and between bar tail, be provided with annular fracture groove, in described bar He on bar tail, be equipped with the compact arranged annular groove of indentation, the riveting cover that is provided with through hole for middle part is overlapped in described riveting, described riveting cover coordinates with rivet bar.
Preferably, the diameter of described rivet bar is 5mm-10mm, and the length of described bar head is 4mm-26mm, and the length in described bar is 6mm-12mm.
Preferably, described round end and rivet bar adopt alloy aluminum one-body molded, and described riveting cover is alloy aluminum riveting cover.
Preferably, described round end and rivet bar adopt copper one-body molded, and described riveting cover is copper riveting cover.
Preferably, described round end and rivet bar are that stainless steel is one-body molded, and described riveting cover is stainless steel riveting cover.
Preferably, described round end is that top is the round end of plane, or described round end is the outwards mushroom head round end of arch of top.
The beneficial effects of the utility model are:
The utility model utilizes Hooke's law principle, after 2 conjunctions of needs riveted joint being clamped with pulling rivet special device, by the extruding metal of the riveting cover being inserted in (for circumferential collar) and be filled to position in the bar of the rivet bar of many annular ditch grooves, make a kind of fastening means of riveting cover and the tight combination of rivet bar.Therefore, every ring-groove-type rivet has the characteristics such as identical fastening force and never becoming loose after assembling completes.Ring-groove-type rivet can be used for generally needing the parts of bolt or riveted joint.The performances such as high fastening force, never becoming loose and the high shearing resistance producing due to ring-groove-type rivet, ring-groove-type rivet also can be used to replace welding.
It can realize two-sided riveted joint the utility model, and riveted joint is firm, is difficult for becoming flexible, and can be widely used in the fastening fields such as various vehicles, boats and ships, aviation, building, bridge.
