Description
Technical field
The utility model relates to a kind of antitheft door lockset, particularly a kind of lock core.
Background technology
At present, the safe-guard door lock generally using comprises lock core and jam plate, lock core is arranged in the lock core hole arranging on jam plate, lock core comprises lock body, turning wheel, door inner side lock core, outer side of door lock core, two ends at lock body are provided with lock core mounting hole, in door, outside lock core lays respectively in the lock core hole at same lock body two ends, on door inner side lock core and outer side of door lock core, be provided with keyhole, turning wheel is inside door between lock core and outer side of door lock core, existing turning wheel is one, in turning wheel, be placed with shifting shaft core, shifting shaft core comprises back shaft, thumb wheel core, thumb wheel core is two, they are enclosed within on back shaft respectively actively, on two thumb wheel cores, be provided with the shifting block that can drive turning wheel to rotate, at the door inner side lock core near turning wheel, one end of outer side of door lock core is provided with the shifting block draw-in groove corresponding with shifting block, when such theftproof lock is arranged on and uses on security door, door inner side lock core, outer side of door lock core lays respectively at the both sides of security door, by key, insert and in the keyhole on door inner side lock core or outer side of door lock core, promote shifting shaft core and move, the shifting block that makes to insert on the thumb wheel core of key one end is stuck in stirring in groove of turning wheel on one side, be stuck in the shifting block draw-in groove on lock core on one side, under the rotation of key, drive the rotation of door inner side lock core or outer side of door lock core that shifting block is rotated, shifting block rotates and drives turning wheel to rotate, realization is opened the door or door is locked, because current anti-theft door lock cylinder is all by lock core inside door, outer side of door lock core is controlled same turning wheel and is rotated, realization is opened the door or door is locked, in use, on the lock core in security door one side, first insert after key, the key first inserting moves promoting the lock core of shifting shaft core to security door opposite side, make a thumb wheel core that does not insert key end move to stirring outside groove on turning wheel, the key first inserting rotates again, to drive turning wheel to rotate, after turning wheel rotates, the shifting block being positioned on the thumb wheel core outside turning wheel misplaces with the groove of stirring of turning wheel, be positioned at the space that shifting shaft core outside turning wheel has taken the keyhole of the lock core that does not insert key end, shortened the length of the keyhole that does not insert key end lock core, under the state that the key formerly inserting does not take out, to another lock core of security door, insert key again, the key of rear insertion moves the thumb wheel core of stirring groove dislocation that can not promote with turning wheel, in the keyhole of the insertion lock core that the key of rear insertion can not put in place completely, key can not rotate, just can not realize and opening the door or the action of counter-locking a door.
While opening the door as the insertion of lock core inside door key, key can promote shifting shaft core and move to outer side of door lock core direction, make the thumb wheel core matching with outer side of door lock core shift out the groove of stirring on turning wheel, rotating key opens door, people goes out rear and forgets and take out the key being inserted on an inner side lock core, again door has been closed because of carelessness, so now, when people inserts on outer side of door lock core by identical key again, because the key being inserted with on lock core inside door has propped up shifting shaft core, the key that outer side of door lock core inserts can not promote with turning wheel on the thumb wheel core of stirring groove dislocation, shifting block can not enter stirring in groove on turning wheel, key can not insert in the keyhole of outer side of door lock core on request completely, the key inserting on outer side of door lock core just can not rotate, just can not open door.In like manner, while opening the door as inserted key at outer side of door lock core, key can promote shifting shaft core and move to lock core direction inside door, rotating key opens door, people leaves rear and forgets that taking-up is inserted in the key on outer side of door lock core, again door has been closed because of carelessness, so now, when people inserts key on the lock core of door inner side again, because the key being inserted with on outer side of door lock core has propped up the shifting shaft core of door inner side lock core end, shifting shaft core has taken the space of not inserting key end lock core keyhole, shortened the length of the keyhole that does not insert key end lock core, key can not insert in a keyhole of inner side lock core completely on request, the key inserting on the lock core of door inner side just can not rotate, just can not open door, such lock core is used extremely inconvenient, normal giving can people's daily life be brought many troubles.
Existing lock core is in routine use process, when going out, forget and take off the key inserting after indoor opening the door, and don't carefully door is shut, now, outdoor people rethinks and enters house, with identical key, insert outdoor outer side of door lock core upward-acting door, key can not insert in outer side of door lock core keyhole at all completely on request, cause key not rotate and cannot open the door, Chang Yin goes to pivot frame family and falls to death tumble injury, also often cause firefighters to go rescue and wasted manpower and materials (often having this type of event report on TV), using inconvenience.When evening indoor people for the sake of security, with key, after indoor counter-locking a door, forget and take off key, the people who returns from the outside midnight can not open the door from outdoor insertion key turns too, the people who only wakes indoor sleep opens door.Equally, when going out very early, if door is forgotten and taken off key from outdoor locking, indoor people can not open the door from indoor insertion key turns, and when the emergencies such as breaking out of fire, indoor people cannot escape.So traditional security door mechanical lock is used extremely inconvenient, bring many troubles often to people's daily life; When serious, also can cause casualties and property loss beyond thought trouble perhaps, therefore, original mechanical lock can not adapt to the needs of the current life development of people's door.
