Abstract
A door lock device is provided and includes: a lock assembly having a first lock structure and a second lock structure; an acting assembly interlocked with the first lock structure and the second lock structure; and an operation assembly interlocked with the acting assembly so as to unlock the first lock structure and the second lock structure synchronously. Therefore, when the lock assembly is in the form of top and bottom locks, the top and bottom locks can be unlocked at the same time, so as to allow an escape door to be opened quickly, thereby facilitating emergency escape.
