Description
Technical field
The present invention relates to a kind of mechanical automatic lock, relate in particular to a kind of automatic anti-theft door lock.
Background technology
Safe-guard door lock is for realizing the locking between door and doorframe, and door lock is mainly to utilize institute's bolt to be plugged in frame hole and the locking that realizes opposite house, realize the unlatching of door, is generally to utilize key to pull tapered end, and tapered end drives locking bolt to move by transmission mechanism. Based on the consideration of safe-guard door lock theftproof performance, on most safe-guard door lock, be provided with master latch, retainer and latch bolt, make lock core drive these locking bolt actions, transmission mechanism need to be set in lock body. In existing safe-guard door lock, set drive mechanism is relatively complicated, and this makes the weight of safe-guard door lock entirety larger, and production cost is high, and in actual use procedure, fault rate is also relatively high.
Chinese patent literature CN202064726U discloses a kind of Simple antitheft door lock, comprise lock body, be located at the master latch supporting plate in lock body, in lock body, be articulated with gear plate, the outer edge of gear plate is provided with moving tooth, the two ends of one supporting plate connecting rod are hinged with master latch supporting plate and gear plate respectively, the pin joint being hinged with supporting plate connecting rod on gear plate is positioned at the eccentric position place of gear plate, in lock body, be hinged with location claw, the outer end of location claw is provided with arc dop, think that at gear plate outward flange corresponding position is provided with the bayonet socket matching with dop shape, between location claw and lock body, be provided with spring, on master latch supporting plate, be connected with master latch, master latch can be followed master latch supporting plate and stretched out or retract in lock body, in lock body, also need to be provided with tapered end, on tapered end, there is gear, the tooth that pulls out that gear is provided with gear plate edge is meshed, gear driven gear plate in the time rotating rotates, gear plate passes to supporting plate by supporting plate connecting rod power, on lock body, be provided with gathering sill, on supporting plate, be provided with the guide finger being plugged in gathering sill, in the effect of supporting plate connecting rod, supporting plate drives master latch reach lock body outside or be locked in lock body, thereby complete locking and the unlatching of door lock. in the Simple antitheft door lock described in above-mentioned patent documentation, to carry out driven gear plate by the gear on tapered end to rotate, gear plate drives master latch supporting plate to stretch out and indentation by supporting plate connecting rod, realizes the locking of stretching out with indentation state by the buckle by gear plate and location claw.
But the Simple antitheft door lock described in above-mentioned patent patent documentation, while making to open the lock with the key, to rotate and realize by rotation tapered end driven wheel plate, and while unblanking by handle, to drive latch bolt driving lever to rotate by handle rotating master lock hyoplastron is retracted, thereby and then rotate and drive universe rod to retract simultaneously by supporting plate connecting rod driven gear plate, therefore, the theft-proof door lock structure more complicated of the prior art, the more important thing is because handle is not that the mode driving gear wheel plate directly engaging by gear rotates, but pass through three intermediate members: latch bolt driving lever, master lock hyoplastron, the linearly operating that the spinning movement of handle is converted to master lock hyoplastron by the supporting plate connecting rod of eccentric setting is converted to that the action of supporting plate connecting rod eccentric rotary realizes again, therefore, processing assembling to each part requires high, slightly error, may just cannot realize successfully and locking out completely, stability is bad, easily be out of order, and use underaction, feel is bad.
