The utility model relates to a structural improvement for cipher locks with keys, which comprises a lock body, a lock hook, a cipher wheel, a lock hook sleeve, and a lock core, wherein a hole slot for the lock hook to move up and down is arranged on the lock body; a screw thread sleeve is additionally arranged between the lock hook sleeve and the lock core; the lock hook sleeve is connected with the screw thread sleeve by screw threads. The screw thread sleeve which is connected with the lock hook sleeve by the screw threads is additionally arranged between the lock hook sleeve and the lock core by the structural improvement for cipher locks with keys. When a key is used for unlocking, the lock core is driven by the key to rotate and the screw thread sleeve is driven by the lock core to rotate together. Because the lock hook sleeve is connected with the screw thread sleeve by the screw threads, the lock hook sleeve is rotated to descend until the lock hook sleeve is disengaged from the lock hook. Thus, the purpose of unlocking is realized. The lock hook does not need to be depressed by hand for unlocking any more, and the use of the structural improvement for cipher locks with keys is more convenient.
