Abstract
A handle-locking mechanism for a door comprises a sliding bar, a locking member and a rotatable member all inside a lock body, wherein the rotary motion of the rotatable member drives an upper latch and a lower latch to a locking position and unlocking position; the sliding bar is slidably arranged inside the lock body and one end of the sliding bar abuts against the bolt, and the sliding bar is provided with a first elastic element, and the sliding bar is pushed against the elastic force from the first elastic element when the bolt retracts; the locking member is coupled with the sliding bar, and when the bolt stretches out, the locking member is brought by the sliding bar to a position to block the rotary motion of the rotatable member.
