Abstract: A horizontal locking case lock includes a coupler fastened to a case and a lock with a housing surface latchable horizontally by the coupler for locking. The coupler includes at least a first wedge portion and at least one latch trough. The lock contains a locking mechanism. The locking mechanism drives and controls movement of a first retainer to further drive a second retainer to force a steel ball into or out of the latch trough, thereby control locking or unlocking of the coupler and the lock. Such a structure can safely lock the case at a public location to avert hitting and pilferage.
