DETONATION DEVICE OF MECHANICAL BLASTER Russian patent published in 2003 - IPC

Abstract RU 2202765 C2

FIELD: blasting operations, blasters activated by mechanical load. SUBSTANCE: body comprising bushing and sleeve fastened together with nut houses firing pin freely mounted in bushing on blasting cap, transmission charge, detonator placed in sequence and axial conduit made in sleeve between blasting cap and transmission charge. Firing pin is anchored in bushing with the help of fixing member in the form of cylindrical cap made of hard metal resting against firing pin and attached to external surface of bushing by means of elastic heat-resistant material. Face surface of blasting cap is fixed with clearance with reference to face surface of sleeve to enhance safety of assembly of detonation device. EFFECT: increased reliability of activation of device, diminished value of energy of impact required for its activation, enhanced safety of assembly of detonation device. 2 cl, 1 dwg
