Abstract

An anti-theft lock head includes a lock cylinder sleeve, a lock cylinder and a return device. The lock cylinder is provided with a key slot, an inner pinhole, a left inner installation hole and a right inner installation hole. The key slot includes an upper slot, an arc-shaped bevel contraction slot and a lower slot. The arc-shaped inclined-plane contraction slot is located between the upper slot and the lower slot. Between them, the lock cylinder sleeve is provided with a lock cylinder hole, an outer marble hole, a left outer installation hole and a right outer installation hole. The bilateral clearance s, the bilateral clearance t and the bilateral clearance u are not equal to each other. In the lock cylinder hole, an upper spring, an upper flat pin and an upper semi-round pin are successively installed in the outer pin hole and the inner pin hole, and the outer pin hole is closed by a plug. The return device includes a left spring, a left flat pin and a left semi-round pin which are sequentially installed in the left inner mounting hole and the left outer mounting hole, and a right spring and a right flat pin which are symmetrically installed in the right inner mounting hole and the right outer mounting hole. The marble and the right semi-round-headed marble, and the left outer mounting hole and the right outer mounting hole are closed by a plug.

Description

Technical field [0001] The invention relates to a lock head component of a pin lock, in particular to a lock head of an anti-theft lock.
