Abstract: The present invention relates to a landing-door door lock device. The following problem is solved: the position of a lock ball of a general landing-door door lock device is not adjustable, and adjustment is complicated when there is a deviation between positions of the lock ball and a door knife. The device includes a primary lock and a secondary lock, the primary lock includes a bottom plate and a locking arm, a counter weight is mounted on the locking arm, a moving ball is fixed onto the counter weight, a fixed ball is mounted on the bottom plate, the secondary lock includes a buckle plate, the locking arm is connected onto the bottom plate through a rotary shaft, an arc-shaped hole is opened on the counter weight, a shaft sleeve is sheathed on a shaft of the fixed ball, the shaft sleeve penetrates into the arc-shaped hole, a front end of the buckle plate is provided with a first lock hook, the locking arm is correspondingly provided thereon with a lock column, and the first lock hook is buckled on the lock column. The present invention has the following advantages: the rotary shaft and the fixed ball are disposed separately, the positions of the fixed ball and the moving ball can be adjusted left and right, when there is a deviation between positions of the lock ball and the door knife of the landing-door door lock device on different floors, it is not necessary to adjust the position of the door lock of the whole floor, so adjustment is simple, and a problem of poor contact occurring in electrical contacts on the door lock is also avoided.
