Abstract

The invention provides a bolt locking mechanism and a door lock with the same. The bolt locking mechanism comprises a safety rotary knob and at least two locking structures linked with the safety rotary knob; and at least one locking structure is arranged on each of the two sides of the center line of a bolt driving mechanism in the bolt in-out direction, after a bolt retracts into a lock shell, the locking structures can act by screwing the safety rotary knob, and the two ends of a bolt fixing plate used for being connected with the bolt are locked at the same time. The bolt locking mechanismis provided with the safety rotary knob in linkage with the at least two locking structures, at least one locking structure is arranged on each of the two sides of the bolt driving mechanism correspondingly, the locking structures can act by screwing the safety rotary knobs, and the two ends of the bolt fixing plate used for being connected with the bolt are locked at the same time by the lockingstructures; and after the bolt retracts into the lock shell, the structure is adopted for locking the bolt, the bolt cannot be inclined, and the bolt can be completely hidden in a lock shell face plate.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a bolt locking mechanism and a door lock having the same. Background technique [0002] The self-spring lock body is to automatically pop out when the door is closed when the bolt hits the door frame, realizing automatic locking. When there are many guests coming in and out at home, it is necessary to turn the safety knob to catch the bolt to realize the normal open mode. The door is closed but the bolt does not pop out. locked. [0003] In the door locks in the prior art, in order to ensure that the lock-in and lock-out actions of the deadbolt can be carried out stably and smoothly, a deadbolt driving mechanism is usually set in the middle of the lock housing, so that the safety knob and its supporting holding mechanism are It will be set at a position deviated from the middle part of the lock housing. The safety knob is used to withstand the lock tongue so that it does not ...
