Abstract
The utility model discloses an opening and closing lock cylinder which comprises a lock cylinder casing, a keyway, a turning wheel, a key, driver pins and key pins. Springs abut against the key pins, and sealing steel balls abut against the springs. At least one of the driver pins is equal to the distance from the top of the key back to the separation position of the keyway and the lock cylinder casing in length, and key teeth corresponding to the pins are in a punched structure. The opening and closing lock cylinder has the advantages that the anti-theft performance is good, a lock cannot be opened without an original key in the prior art, and the anti-theft level is high.
Description
Technical field
The utility model relates to a kind of lock core, particularly a kind of anti-theft lock core.
Background technology
The existing market upper lock core is prevented technical opening, common two kinds of methods: 1, manually dial pellet shot from a slingshot, add that tin platinum soft durometer is moderate can open, and like the computer lock pin, single double; 2, electronicly unblank, design the identical key instrument of various grooveds, with the method last 90% lock (comprise most of blade lock) of can opening up markets.
The utility model content
To the deficiency of existing anti-technology unlocking, the utility model provides a kind of keying lock core, solves manually with electronic according to the present method problem of unblanking.
To achieve these goals, the technical scheme taked of the utility model is:
The keying lock core comprises lock core shell, lock core shaft, and thumb wheel, key, last pellet shot from a slingshot and following pellet shot from a slingshot, there is spring on the outer top of following pellet shot from a slingshot, and spring pushes up the steel ball of sealing up a door down.At least one length overall equals in the last pellet shot from a slingshot: the place is separated at key back of the body top with lock core shell to lock core shaft distance.The key tooth flower that said pellet shot from a slingshot is corresponding is the perforated structure.
The beneficial effect of the utility model: theftproof performance is better, does not have first wife's the present technology of key can't open lock, and higher grade of antitheft.
Description of drawings
The state diagram that Fig. 1, the utility model lock core are not opened;
The state diagram that Fig. 2, the utility model lock core are opened;
The Key structure figure of Fig. 3, the utility model.
The specific embodiment
Open and close lock core; Comprise lock core shell 1, lock core shaft 2, thumb wheel 5, key 3, last pellet shot from a slingshot 4 and following pellet shot from a slingshot 6, there is spring 7 on following pellet shot from a slingshot top; Spring pushes up the steel ball 8 of sealing up a door 7 times, and at least one length overall equals the place is separated in key back of the body relevant position, top to lock core shaft 2 and lock core shell 1 distance in the last pellet shot from a slingshot.This pellet shot from a slingshot is called as pellet shot from a slingshot 9 No. 0.No. 0 pellet shot from a slingshot 9 can be arranged on optional position in the pellet shot from a slingshot arrangement.As shown in Figure 1, when not unblanking, No. 0 pellet shot from a slingshot 9 when static, is in opening and other pellet shot from a slingshot is in card when static closes state.
When unblanking with first wife's key, because perforation relation lets pellet shot from a slingshot 9 openings No. 0, other pellet shot from a slingshot is also opened simultaneously.
Could open other pellet shot from a slingshot if must pass No. 0 pellet shot from a slingshot 9 with technical opening, No. 0 pellet shot from a slingshot 9 snaps in lock core shell 1 so, so can not open.
To the special-purpose original key of above-mentioned lock, key 3 is provided with and the corresponding tartar through hole of No. 0 pellet shot from a slingshot that opens and closes lock core.
The above embodiment is a kind of of the more preferably concrete embodiment of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
