Abstract
An electronic door lock with up-pushed locking is provided and includes a housing, a fixed latch assembly assembled in the housing, a linkage member and a first driving member. The first driving member is linked with an outer handle located outside a door. When a user lifts the outer handle, the first driving member is pulled to drive the linkage member, so that the linkage member abuts against a protruding rod located at a rear end of the fixed latch assembly, thereby pushing the fixed latch assembly to actuate, so that a fixed latch head of the fixed latch assembly protrudes out of the housing and the electronic door lock is locked. Accordingly, the problem that the user must use a key to lock the electronic door lock when the user is outside the door can be solved.
