Described rock bolt head 2 is reverse wedge shape, and rock bolt head 2 maximum gauge is more than the diameter of bore of described bolt expansion sleeve 1.
Described bolt expansion sleeve 1 is that mechanism's self-locking is connected with anchor pole connected mode.
Described bolt expansion sleeve 1 from first to last internal diameter is equal.
Described annular projection 1-b is taper serration along the axial cross sectional shape of anchor pole.
Work process of the present utility model is:
Utilize sleeve pipe 3 that the bolt expansion being contained in rock bolt head 2 is overlapped 1 and together send in the hole being drilled with anchor pole, then tightening nut 5, when anchor pole head produces relative slip with bolt expansion sleeve 1, bolt expansion sleeve 1 is expanded by the expansive force of rock bolt head 2 and produces powerful frictional force with hole wall, formation mechanism self-locking during meanwhile rock bolt head 2 can embed the gap of sleeve lining annular projection 1-b.
The beneficial effects of the utility model are:
1, the expansion sleeve anchor pole of a kind of band auto-lock function is provided, it is achieved while high pre-stress, ensure that the long-acting reliable anchor force of anchor pole；
2, the bolt expansion set processing of band auto-lock function is simple, high financial profit.
