Abstract: A self-locking cable lock has a main shell, an external sleeve, an internal sleeve, a lock shell, a lock cylinder and a lock actuating assembly. The external sleeve is mounted in the main shell and has a stationary protruding rod extending out of the main shell. The internal sleeve is mounted in the external sleeve, is allowed to move axially relative to the external sleeve and has two movable protruding rods. The movable protruding rods extend out of the external sleeve and have inclined distal ends. The lock cylinder is mounted in the lock shell. The lock actuating assembly is mounted in the lock cylinder. The stationary protruding rod is pushed into a keyhole of a desired appliance and the movable protruding rods can be pressed to move axially. Then the cable lock is able to be self-locking.

Abstract: A cylinder lock includes a locking core rotatably received in a lock housing. A first disk is integrally formed outside the locking core, and a second disk is rotatably provided on the locking core. A channel is longitudinally defined at a center of the locking core, and a shaft with stepped slots is movably received in the channel. A latching member is radially received in the first disk, and has a spherical head partially positioned in the lock housing, and a shank extending in the stepped slots. A correct key has a finger for pushing the shaft inwards, so the latching member can be released from the lock housing to enable the locking core to turn about the lock housing. Whereby, the cylinder core has a high level of security.
