| Zusammenfassung: | An improved door lock is provided with a brake mechanism which can be driven by a knob or a key to rotate; one end of the brake mechanism is provided with a spring which can provide an elastic storage energy for driving the mechanism to rotate; besides, an elastic element which can provide an elastic force to the brake mechanism is pivoted below the brake mechanism, thus helping an embedding rod to slide on a first locking position, an ejection position and a second locating position on the arc embedded hole of the bolt in turn and driving the mechanism to achieve complete actuation; besides, the improved door lock is provided with a safety mechanism which can limit the rotation of the brake mechanism and is provided with a probing rod which can be pressed to allow the brake mechanism to rotate, thus avoiding the bolt from extruding out in a careless state to cause dangers. |
