Description
Affiliated technical field
The utility model relates to a kind of lockset and key, particularly relevant for a kind of lockset and key thereof with key of spirality push rod.
Background technology
The patent No. is 200410087826.2 to disclose a kind of spiral key mechanical cylinder lock with balls, comprise that core, key, dead bolt, bolt move piece, handle base etc. opens the door, it is characterized in that: be provided with at least two spiral bar on the key, spiral bar is provided with hoodle position key bit, be provided with the helicla flute that matches with spiral bar in the keyhole of core, helicla flute is provided with the hoodle hole of matching with hoodle position key bit.The handle place that is subjected at key is provided with a kink.Hoodle places in the hoodle hole, and core places in the lock core base, and the core drive link places and revolves in the driving lever, revolves driving lever and is installed in off-centre and hits and move by the bar, and bolt moves the piece front end and places by the dead bolt, and the rear end places by the bolt, and the oblique cone collision block of locking is installed and liked that bolt moves the piece rear end.When locking, at the outdoor button of locking of pressing, or indoor draw on locking bar, then drive the oblique cone collision block of locking and return bolt and move the piece rear end, make bolt move the piece front end and replace the bolt tongue, door lock is locked.When unblanking, hand is grabbed on kink, at outdoor insertion key, because key is spirality, must rotate and insert, kink is caught by hand and motionless, after inserting key, screw key, core drive link drive and to revolve driving lever and press to off-centre and hit and move bar, and off-centre is hit and moved bar and press to bolt and move piece, bolt moves fast front end and leaves dead bolt, rotate outer handle, drive the handle base shifting block dead bolt is departed from, lock leaves.This utility model need be processed helicla flute in the keyhole of core, complex process also makes cost improve simultaneously.
Summary of the invention
In order to overcome the shortcoming of above-mentioned patent, the purpose of this utility model provides a kind of lockset with spiral key, can make the lockset saboteur can't see key channel.In addition, another purpose of the present utility model is not need to process helicla flute, so cost is cheap relatively.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spiral key theftproof lock, comprise pin housing, lockhole cap, attachment pegs, fairlead and key, described lockhole cap links up by several attachment pegs and movable core, with the common annular space that forms a sealing of the fairlead of centre, described key comprises a spiral pellet shot from a slingshot push rod at least, and the circumference of described movable core is provided with at least one cover pellet shot from a slingshot system.
For better antitheft, the pellet shot from a slingshot system that distributes twist that a plurality of and above-mentioned spiral pellet shot from a slingshot push rod matches also can be set on the circumference of described movable core, corresponding described spiral pellet shot from a slingshot push rod is provided with some hoodle holes of matching with this pellet shot from a slingshot system.Described pellet shot from a slingshot system comprises spring, several pellets shot from a slingshot and lead sealing.Described lockhole cap is provided with the tangential entrance hole of at least one spiral.Under nondestructive condition, because pellet shot from a slingshot is lived by the lockhole cap protection, the spirality key of non-special use can't touch, so can prevent the unlatching of omnipotent key effectively.If lockhole cap Mining alloy steel material can also pick-proof.
In order to strengthen the intensity of key, also can establish a lead in the centre of described key, the next door is a spiral pellet shot from a slingshot push rod, simultaneously the middle corresponding circular pilot hole of establishing on described lockhole cap.Described spiral pellet shot from a slingshot push rod has rectangle, circle or polygonal different section shape with the axis of guide.Described lockhole cap can be made of one with described movable core.
Operating principle of the present utility model is: lockhole cap links up by several attachment pegs and movable core, with the common annular space that forms a sealing of the fairlead of centre, after locking lockset, movable core (comprises lead sealing by the pellet shot from a slingshot system, spring and several pellets shot from a slingshot) link up with the pin housing, when key by lockhole cap on rotation when inserting, the spiral handspike of key enters the annular space of above-mentioned sealing along the spiral tangential hole, thereby the pellet shot from a slingshot of the pellet shot from a slingshot system of arranging twist on the circumference of movable core is ejected rotation activity core, and drive drive link lock is opened.
The beneficial effects of the utility model are: compare with other spirality lockset, this patent is provided with the hoodle hole cleverly on the spiral handspike of key, on the circumference of movable core, be provided with simultaneously the pellet shot from a slingshot system of distribution twist that several match with the hoodle hole of above-mentioned spiral pellet shot from a slingshot push rod, saved processing spiral fluted trouble, reached and have the spiral fluted effect.It is simple to have processing, advantage with low cost.
