Technical Field

The invention relates to the field of locks, in particular to a door lock device.

Background

The door lock generally has a front handle and a rear handle, and for partial door locks, when an electronic lock body is adopted, a lock head is arranged on the front handle, and can be unlocked through a clutch structure or the lock head, and then the front handle is rotated to achieve the purpose of unlocking. The rear handle is linked with the lock tongue device on the lock body, and the lock tongue device can be directly driven to act by rotating the rear handle, so that the aim of unlocking can be fulfilled.

To the door lock of above-mentioned structure, when needs utilize the tapered end that is located on hand to unblock, all insert the tapered end with the key, promote the square bar and remove one end distance, lead to separation and reunion structure inefficacy, rotate the preceding handle this moment and can directly unblank.
