Buckle lock assembly

A buckle lock assembly adapted to be mounted on a first locked unit and a second locked unit, and being capable of locking the first locked unit and the second locked unit;

• the buckle lock assembly comprising:
• a hook unit adapted to be securely mounted on the first locked unit;
• a fixing base adapted to be securely mounted on the second locked unit and having
• a locking segment;
• a wrench unit pivotally mounted on the fixing base;
• a buckling ring unit pivotally mounted on the wrench unit and selectively clasping the hook unit;
• and
• a lock securely mounted on the wrench unit;
• the lock being a tubular lock and having:
• a lock base unit fixed on the wrench unit;
• a lock cylinder base mounted in the lock base unit and fixed with the lock base unit;
• an axle segment rotatably mounted in the lock cylinder base;
• the lock cylinder base and the axle segment each form multiple holes corresponding in position with each other;
• a buckling unit mounted on the axle segment and rotating along with the axle segment;
• multiple second lock bolts respectively movably mounted in the holes formed on the lock cylinder base, and pushed by springs to protrude out of the holes formed on the lock cylinder base and to protrude into the holes formed on the axle segment, thereby preventing the axle segment from rotating relative to the lock cylinder base;
• when a corresponding key is inserted, the second lock bolts configured to be pushed by the key such that the second lock bolts detach from the holes formed on the axle segment, thereby allowing the axle segment to rotate relative to the lock cylinder base;
• wherein
• when the lock is in a locked state, the buckling unit of the lock engages with the locking segment of the fixing base to limit the wrench unit pivoting relative to the fixing base to lock the first locked unit and the second locked unit;
• and
• when the lock is in an unlocked state, the buckling unit of the lock disengages from the locking segment of the fixing base to allow the wrench unit to pivot relative to the fixing base.
