Abstract
The utility model discloses a novel anti-theft locking head and a key thereof. The locking head comprises a locking head shell and a lock liner, wherein the locking head shell and the lock liner are provided with main marble holes which correspond to each other; the two sides of the main marble holes are provided with a row of auxiliary marble holes respectively; the inside of the main marble hole on the lock liner is provided with a pressing bead; the inside of the marble hole of the locking head shell is provided with a flat bead and a pressing bead spring; the insides of the auxiliary marble holes are provided with anti-dialing beads; the key matched with the anti-theft locking head is provided with three rows of key teeth matched with the pressing bead and the anti-dialing beads; when the key is inserted, the tail ends of the anti-dialing beads and the pressing bead are flushed with the surface of the lock liner, then a lockset is unlocked; when the lock is open by technology or force, regardless of the rotation direction of the lock liner, the lock liner is relocked in the auxiliary marble holes or the main marble hole by the flat bead or presses the anti-dialing beads into the main marble hole on the locking head shell so as to lock the lock liner and the locking head shell when the auxiliary marble holes are flushed with the main marble hole of the locking head shell; therefore, a second defense line is formed structurally which effectively reduces the possibility of technical unlocking and improves the security of the lockset.
Description
Technical field
The utility model relates to a kind of lockset, particularly a kind of tapered end and key that is applicable to mechanical lock.
Background technology
Present lockset mostly is mechanical cylinder lock greatly.The tapered end of this cylinder lock comprises the tapered end shell and is assembled in the interior lock gall of tapered end shell, on lock gall and tapered end shell, be respectively equipped with the pellet shot from a slingshot hole of mutual correspondence, the pellet shot from a slingshot that can slide along the pellet shot from a slingshot hole is housed in the pellet shot from a slingshot hole, when the key that no key inserts or inserts does not match, pellet shot from a slingshot is being stuck under the thrust of marble spring between lock gall and the tapered end shell, make that lock gall is relative with the tapered end shell to be locked, when the key of coupling inserts lock gall, the pellet shot from a slingshot that spoon tooth on the key will be stuck between lock gall and the tapered end shell pushes in the pellet shot from a slingshot hole of tapered end shell, lock gall and tapered end shell can be relatively rotated open lockset.
Yet, present its lock gall of this mechanical lock and tapered end shell only are provided with the corresponding mutually pellet shot from a slingshot hole of a row, in case master key is unblanked or technology unlocking will be arranged pellet shot from a slingshot and push in the pellet shot from a slingshot hole of tapered end shell or this row's pellet shot from a slingshot of violence damage, just can rotate lock gall, open lockset, and, because keyhole and key on present its lock gall of lockset are the tabular that shape adapts, make insertions such as iron plate easily, rotate lock gall after the insertion by force, make the pellet shot from a slingshot distortion and violence unlatching lockset, security performance is not high.
Summary of the invention
