The invention relates to a lock body component of a door lock, and provides a silencing mechanism of a lock tongue component. The silencing mechanism is provided with a lining plate component, a box bottom component, a lock tongue, a lock tongue return spring, a lock tongue guide piece, a lock tongue pull rod and a handle dial, wherein the lock tongue pull rod is arranged at the rear end of the lock tongue; the middle part of the lock tongue pull rod is embedded into a lock tongue pull rod fixing frame; the lock tongue return spring and the lock tongue guide piece are both arranged on the lock tongue pull rod in a penetrating manner; the lock tongue pull rod is also provided with a silencing fixing sleeve in a penetrating manner; the silencing fixing sleeve consists of a silencing fixing sleeve front cover, two O-shaped rings and a silencing fixing sleeve rear cover; a damping cavity is arranged in the center of the silencing fixing sleeve front cover; damping resin is filled into the damping cavity; the two O-shaped rings seal the damping resin in the damping cavity. Through the technical scheme, the collision noise between door lock parts is further reduced, and the silencing fixing sleeve has an exquisite structure, high applicability and quite stable performance.
