Abstract
The utility model relates to a lock core of a spiral key hole and a spiral key, which is provided with the columnar lock core which is composed of a columnar inner core body and a circle sleeve-shaped outer core body which is fixedly assembled with the columnar inner core body. The spiral key hole is arranged along a matching surface of the inner and the outer core bodies. The spiral key is arranged to be matched with the key hole. A key tooth fossa is arranged on the key and is corresponding to a pin tumbler which is configured on the outer core body. The utility model adopts the lock core with the spiral key hole and the spiral key, and alters a traditional straight channel key hole structure of a mechanical pin tumbler lock thoroughly to make lock prizers difficult to use non key tool to turn and prize the pin tumbler from the key hole to carry out unlocking, or use strong and hard object to carry out destructive unlocking through the key hole. Therefore, the safety of the lock is enhanced.
Description
Technical field
The utility model relates to mechanical cylinder lock and key, is a kind of lock core and spiral key with spiral key hole specifically, is the technological improvement of doing for the security reliability that improves existing mechanical cylinder lock.
Background technology
Traditional mechanical cylinder lock, generally the through hole of confession key insertion and the lock core structure that corresponding keyhole radially assembles pellet shot from a slingshot are offered in the employing center, and the key of Pei Heing is toothed straight cylinder structure with it.Because keyhole is straight way shape hole, and pellet shot from a slingshot is a straight line and distributes, thus touched pellet shot from a slingshot by non-key-shaped tool easily, and easily lock is opened.In addition, the keyhole of the straight way shape person of also being convenient to the picking lock uses strong thing to insert to implement destructiveness in the keyhole and unblanks.The anti-pick-proof poor performance of dialling of therefore locking, security reliability is low.For improving the safety and reliability of traditional straight way pass cylinder lock, prior art discloses several be key that reverses column type and the lock bodies that spirality hole wall lockhole is set, because a non-straight line of the non-straight wall construction of lockhole and pellet shot from a slingshot is arranged, increased group difficulty of prying open lock, but its agent structure remains the central through hole form, therefore use non-key-shaped tool still can contact pellet shot from a slingshot and dial and pry open lock, and still exist the strong thing of easy use and insert keyhole and implement the problem that destructiveness is unblanked.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of lock core and spiral key with spiral key hole is provided, the configuration of this lock core and key can effectively limit to be used non-key-shaped tool to dial to pry open key and uses strong thing to insert keyhole to implement destructiveness and unblank, thereby improves the safety and reliability of mechanical cylinder lock greatly.
The technical scheme that realizes above-mentioned purpose is: the lock core and the spiral key in a kind of spiral key hole, it comprises the column type lock core that is provided with pellet shot from a slingshot hole radially and disposes pellet shot from a slingshot, described lock core is made up of the round casing external core of cylinder core body and fixing assembling with it, and is provided with spiral keyhole along the fitting face of inside and outside core body; Matching with keyhole is provided with spiral key, its on the key be disposed at external core on the corresponding key bit nest that is provided with of pellet shot from a slingshot.
The utility model adopts lock core and the spiral key with spiral key hole, thoroughly changed traditional straight way type keyhole, the person that makes the picking lock is difficult to dial the sled pellet shot from a slingshot with non-key-shaped tool from keyhole and unblanks and use strong thing to unblank by keyhole enforcement destructiveness, and the security reliability of lock is improved greatly.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Embodiment describes the specific embodiment of the present utility model in conjunction with the accompanying drawings.
Provide as accompanying drawing, the utlity model has, on external core, be furnished with radially the pellet shot from a slingshot hole twist and also assemble pellet shot from a slingshot 4 respectively by cylinder core body 1 and the column type lock core formed with round casing external core 2 of its fixing assembling.Be processed with spiral groove respectively on the face of cylinder of inner core-body and on the cover inwall of external core, external core assembling back forms the spiral key hole along inside and outside core body fitting face in it.Matching with keyhole is provided with spiral key 3, and the outside of its helical structure is respectively arranged with key bit nest 5 corresponding to the pellet shot from a slingshot on the external core on key 3.During concrete enforcement, tooth nest 5 can be arc, circular arc pit, also can be arc, circular groove; The spire of key is fit to be arranged to circular cross-section or elliptic cross-section.
The utility model is suitable for various mechanical cylinder locks with circular lock core hole.
Claims (1)
1, the lock core and the spiral key in a kind of spiral key hole, comprise the column type lock core that is provided with pellet shot from a slingshot hole radially and disposes pellet shot from a slingshot, it is characterized in that: described lock core is made up of the round casing external core (2) of cylinder core body (1) and fixing assembling with it, and is provided with spiral keyhole along the fitting face of inside and outside core body; Matching with keyhole is provided with spiral key (3), its key (3) go up be disposed at external core (2) on the corresponding key bit nest (5) that is provided with of pellet shot from a slingshot (4).
