A self-locking cable lock comprising:
- a cable;
- a main shell attached to the cable and being tubular;
- an external sleeve mounted rotatably in the main shell, being tubular and having
- a front end;
- a rear end;
- an outer wall;
- an inner wall;
- a stationary protruding rod formed on the front end of the external sleeve, extending out of the main shell and having
- a proximal end;
- a distal end;
- an exterior surface;
- and
- two channels oppositely formed axially in the exterior surface of the stationary protruding rod;
- two through holes formed through the front end of the external sleeve and respectively corresponding to the channels in the stationary protruding rod;
- a slot formed longitudinally in the inner wall of the external sleeve;
- and
- a passing hole formed through the inner and outer walls of the external sleeve and being opposite to the slot;
- an internal sleeve mounted in the external sleeve, moveably with respect to the external sleeve, rotating simultaneously with the external sleeve and having
- a front end;
- a rear end;
- a sidewall;
- two movable protruding rods formed separately on the front end of the internal sleeve, extending out of the through holes in the external sleeve and slidably held respectively in the channels in the stationary protruding rod, and each movable protruding rod having an inclined distal end;
- an annular flange formed around the rear end of the internal sleeve;
- and
- two gaps formed separately in the sidewall of the internal sleeve and respectively corresponding to the slot and the passing hole in the external sleeve;
- a lock shell mounted in the internal sleeve and having
- a sidewall;
- a through hole formed through the sidewall of the lock shell and corresponding to and aligning with the slot in the external sleeve;
- and
- a passing hole formed through the sidewall of the lock shell corresponding to and aligning with the passing hole in the external sleeve;
- a lock cylinder mounted in the lock shell and having
- a stationary segment being tubular, mounted in the lock shell near the front end and having
- a front end;
- a rear end;
- a sidewall;
- a through hole formed through the sidewall of the stationary segment and corresponding to and aligning with the through hole in the lock shell;
- and
- a passing hole formed through the sidewall of the stationary segment and corresponding to and aligning with the passing hole in the lock shell;
- a spring mounted in the internal sleeve and mounted between the front end of the stationary segment of the lock cylinder and the internal sleeve;
- a rotatable segment mounted in the lock shell near the rear end and having
- a front end;
- a rear end;
- and
- an active turning protrusion being semicircular, formed on the front end of the rotatable segment and extending into the stationary segment;
- and
- a locking pin assembly mounted in the stationary and rotatable segments, wherein when the locking pin assembly is locked, the rotatable segment is restricted to be keep from rotatable with respect to the stationary segment and when the locking pin assembly is unlocked, the rotatable segment is allowed to be rotatable with respect to the stationary segment;
- and
- a lock actuating assembly mounted in the stationary segment of the lock cylinder and having
- a guide rod mounted in the stationary segment of the lock cylinder and having
- an outer end extending through the through holes of the stationary segment and the lock cylinder and through one of the gaps of the internal sleeve and extending into the slot in the external sleeve;
- and
- an inner end;
- an actuating rod mounted movably in the stationary segment of the lock cylinder and having
- an outer end extending through the passing holes of the stationary segment and the lock cylinder, selectively extending through one of the gaps of the internal sleeve and selectively extending into the passing hole of the external sleeve;
- an inner end;
- and
- an inactive turning protrusion formed on the inner end of the actuating rod and abutting the active turning protrusion of the rotatable segment of the lock cylinder;
- and
- a spring mounted between the guide rod and the actuating rod and attached respectively to the inner ends of the guide rod and the actuating rod.
