The purpose of this utility model is: a kind of secondary lock of anti-theft door lock is provided, and when the unlatching that realizes this secondary lock and locking, easy and simple to handle.
In order to reach described purpose, the technical solution of the utility model: the secondary lock of a kind of safe-guard door lock, comprise lock body and be located at mobilizable locking bolt in the lock body, in lock body, be provided with main sliding bolt, main sliding bolt connects with described locking bolt is movable, under the drive of main sliding bolt, locking bolt is extended to the lock body outside, or is retracted in the lock body; At least one end of lock body is provided with permeable structures.Permeable structures generally refers to open-work or saturating groove, so that see through permeable structures and link with main retainer in the secondary lock with the joining connector of retainer in the master lock, so that when master lock move, the locking bolt in the drive secondary lock moves together.
Described locking bolt comprises cylindric master lock tongue, and the master lock tongue is provided with attachment pegs, and attachment pegs is plugged in the inclined hole set on the main retainer with gap; Be provided with straight hole at lock body, straight hole is along arranging on the direction of motion of master lock tongue, and described attachment pegs is plugged in this straight hole simultaneously with gap.Straight hole provides guide effect for the action of master lock tongue, generally has the angle of 45 degree between the direction of motion of described inclined hole and master lock tongue, provides motion-promotion force by inclined hole for the master lock tongue during main retainer action.
Described master lock tongue is hollow, and described attachment pegs radially runs through the master lock tongue along the master lock tongue, and the two ends of attachment pegs all are projected into the outside of master lock tongue.The master lock tongue is hollow, has saved the making material of master lock tongue, and needed power when having reduced the motion of master lock tongue has improved the portability when utilizing key that safe-guard door lock is operated.
The length of described main dead bolt is greater than the width of lock body.Correspondingly, the space of moving for the master lock tongue need to be set in the corresponding position of antitheft door.Dimensional requirement between the two makes the volume of this pair lock not need very big.
Described locking bolt also comprises hook-shaped secondary lock tongue, and the secondary lock tongue is hinged in the lock body.Hook-shaped secondary dead bolt has further improved the pick-proof performance of this pair lock.
Be provided with secondary retainer in lock body, main retainer and secondary retainer branch are listed in the both sides of locking bolt, and described secondary retainer and locking bolt are actively coupled.Be provided with major and minor sliding bolt simultaneously, improved the stability of locking bolt when action, made things convenient for connecting between other secondary locks on secondary lock and the same security door or main the lock.
Be provided with the counterweight spring between described secondary sliding bolt and the lock body.The counterweight spring that is provided with has improved smoothness and the stability of secondary lock when action.
Therefore, the beneficial effects of the utility model:
In this secondary lock, drive the locking bolt action by main retainer, and the end of lock body is provided with permeable structures, retainer on main retainer and the antitheft door master lock is linked, when the unlatching that realizes antitheft door or locking, only need to operate master lock by key, the locking of antitheft door and open operation are convenient.This secondary lock simple in structure, wherein the resistance during the locking bolt action is little.
