The invention discloses a false-locking prevention door lock structure comprising a housing. A lock tongue, and a push plate provided with a stirring block and capable of sliding leftward and rightward are disposed inside the housing. A clamp pole is arranged on the bottom end surface of the stirring block, and is located at the clamping position of the push plate. A movable door strip having a U-shaped structure is fixedly connected to the front end of the housing. A connecting rod located in a U-shaped groove of the movable door strip is mounted on the front end surface of the push plate. The connecting rod is provided with a lock slot matching the lock tongue. A lock hook is arranged on the front end surface of the connecting rod. The movable door strip is provided with a strip groove used for making room for the lock hook. A safety block capable of sliding back and forth is amounted in the housing. A circle portion and a square portion are sequentially arranged on the front end surface of the safety block from back to front. The connecting rod is provided with a sliding groove matching the square portion. The sliding groove is provided with a through hole which the circle portion of the safety block can penetrate, so that the square portion can extend from the front end of the movable door strip. The door lock structure is simple and compact, can effectively prevent false-locking phenomena, and has good antitheft effects.
