The utility model discloses an anti-slip stopper mechanism, and relates to the technical field of
continuous casting of
ferrous metallurgy. The stopper rod comprises a mounting arm, a stopper rod body and an anti-falling piece, a U-shaped groove is formed in one end of the mounting arm, the stopper rod body is arranged in the U-shaped groove, an annular through opening is formed in one side edge of the U-shaped groove, a T-shaped through opening is formed in the other side edge of the U-shaped groove, the large opening end of the T-shaped through opening faces inwards, the anti-falling piece comprises a sleeve and a screw, one end of the sleeve is arranged in the large opening end of the T-shaped through opening in a clearance mode, and the other end of the sleeve is connected with the screw. The other end of the sleeve penetrates through the annular through opening and is fixedly provided with a nut, the sleeve is movably connected with the T-shaped through opening and the annular through opening, and a
screw head is arranged at one end of the screw rod. Through the design that the hole is formed in the U-shaped groove and the anti-falling piece is matched, the outer wall of the sleeve is in contact with the circumferential side face of the stopper rod, anti-falling protection can be conducted on the stopper rod, the purpose of stable production is achieved, production safety is improved, meanwhile, self-
assembly and disassembly are convenient and fast, and normal use and replacement of the stopper rod are not affected.
