Level 10.9 short-tail tension rivet

A level 10.9 short-tail tension rivet comprises a rivet body and a sleeving ring, the rivet body comprises a rivet head, a disassembling groove, a polish rod, an annular locking groove section, a threaded section and a tail thin short annular groove section from front to rear, the disassembling groove is arranged at the rear end of the rivet head, the annular locking groove section is matched with the sleeving ring in an extrusion manner, the threaded section is in clamping connection with a sleeving ring latch, and the tail thin short annular groove section is in internal clamping connection with a low riveting force hydraulic riveting device. The curved surface radiuses of annular grooves of each annular locking groove section satisfy the relation that R1>R4, and R2>R3. The inner front end slope angle a of each angular groove of the thin short annular groove section is larger than the inner rear end slope angle b. A sleeving ring flange is provided with projecting points, the latch is arranged at the front end of an inner hole of the sleeving ring, the disassembling groove can eliminate stress concentration in riveting and use. Design of the shape of locking grooves can promote flowing of metal in the sleeving ring during riveting and vibration or pull-apart after riveting is hindered, so that fastening and looseness prevention are improved. Design of the shape of tail grooves enables a clamping claw and the tail to be engaged without tripping, so that riveting with lower riveting force is promoted. The latch of the sleeving ring is used for hooking, and accordingly mounting is convenient. The level 10.9 short-tail tension rivet is used for railway vehicles and heavy trucks which are high in requirements on fastening and reliability.
