Description
Technical field
The utility model belongs to the improvement of door lock core structure, relates to a kind of Three-protecting lock core that can prevent technical opening, anti-drilling, Break preventing key.
Background technology
At present, in the door-plate of every household various door locks are installed all.Common door lock comprises all that generally lock core fixed body, level are installed in lock core and the upper and lower spring marble in the lock core fixed body bottom, and upper and lower spring marble is installed in the through hole in lock core fixed body and the lock core, and keyhole is being set in lock core.Insert corresponding key in keyhole, key promotes the lower spring pellet shot from a slingshot upper spring pellet shot from a slingshot is upwards pushed up, and can drive the lock core rotation by key.Its weak point is this door lock because keyhole is to expose, and is stretched into the technical door lock of opening of lock core by the lawless person by corresponding instrument easily, makes antitheft, the anti-drilling poor performance of door lock.In addition, turn to open, so key also broken off with the fingers and thumb disconnectedly easily, cause door lock to open difficulty owing to drive lock core by screw key when unblanking.
The utility model content
The purpose of this utility model is to provide a kind of Three-protecting lock core, and it is simple in structure, and is easy to manufacture, can prevent technical opening, anti-drilling, Break preventing key, and is easy to use, and low production cost is easy to promote.
The purpose of this utility model is achieved in that a kind of Three-protecting lock core, comprise the lock core fixed body, level be installed in the lock core fixed body bottom lock core and on, the lower spring pellet shot from a slingshot, horizontally set the keyhole of vertically arranging in the lock core fixed body top, on vertical spacing is being provided with from front to back in the lock core fixed body between keyhole and lock core end face, the last through hole of following perforation, said upper spring pellet shot from a slingshot is and is slidingly installed on each in the through hole, vertically be provided with in the lock core and the said lower through-hole that through hole is coaxial and the aperture is identical on each, said lower spring pellet shot from a slingshot is and is slidingly installed in each lower through-hole that the compression spring is housed respectively, and the upper end of lower spring pellet shot from a slingshot is stretched in the last through hole in the lock core fixed body and contacted with upper spring pellet shot from a slingshot bottom surface; The lock core free end that is positioned at keyhole opening below stretches out a horizontal fixed axle is being set, suit a rotation block plate on the horizontal fixed axle, width between rotation block plate inner face and the relative lock core fixed body outer face is greater than the width that is inserted in the key tail exposed junction in the keyhole, the radius of rotation block plate is greater than the distance between horizontal fixed axle center and the lock core fixed body end face, on the radially card of rotation block plate the slit of a width greater than said keyhole width is being set, the stop positioner is being set on the horizontal fixed axle, on the rotation block plate, the stop locating hole is being set, the stop locating hole matches with the stop positioner, constitutes angle between slit and the keyhole.
Because the stop locating hole on the rotation block plate matches with the stop positioner on the lock core horizontal fixed axle, constitutes angle between slit on the rotation block plate and the keyhole; The radius that in addition rotates block plate is greater than the distance between horizontal fixed axle center and the lock core fixed body end face, and the rotation block plate just can block keyhole, carries out skilled unlocking in the keyhole thereby stop the lawless person to stretch into special tool(s) effectively.Rotate the rotation block plate, the two disengaging of stop locating hole and stop positioner cooperated, rotate slit on the block plate just can forward to keyhole in same perpendicular, thereby can key be inserted in the keyhole by slit.After inserting key, key promotes the motion downwards in upper and lower through hole of upper and lower spring marble and makes length of spring compressed in the lower through-hole; At this moment, because the width between rotation block plate inner face and the relative lock core fixed body outer face is greater than the width that is inserted in the key tail exposed junction in the keyhole, so just can rotate the rotation block plate swimmingly again, turn to stop locating hole and stop positioner the two when being combined together, just can be further rotated lock core, open door lock then and open the door.After opening door lock, rotate the rotation block plate again, make the slit aligning keyhole on it extract key for the user.After extracting key, rotate the rotation block plate again, the two matches to make stop locating hole and stop positioner, then rotational lock core enters in the through hole lower spring pellet shot from a slingshot, at this moment, constitute angle between slit on the rotation block plate and the keyhole, thereby realize blocking effectively keyhole.Therefore because the utility model in use, used key does not need rotation, can prevent from that key from twisting off to be stuck in the lock core.The coverage of rotation block plate is arranged in addition and stop keyhole, can also prevent technical opening, anti-drilling effectively.The utility model is simple in structure, is easy to make, and low production cost, easy to use, be easy to promote.
