Abstract
A tumbler lock head and a key thereof comprise a lock shell, a lock core and the key. A key groove is formed in the lock core. A plurality of blade grooves which are arranged perpendicular to the key groove are formed inside the lock core. Blades are arranged in the blade grooves. A locating groove is arranged above the blade grooves in the blade grooves. A locating piece is arranged in the locating groove. A second tumbler groove is arranged at the lower end of the locating piece. A second blocking tumbler is arranged on the corresponding position of the lock core. The width of the second tumbler groove is larger than the diameter of the second blocking tumbler which can be freely arranged on any position below the second tumbler groove. According to the tumbler lock head and the key thereof, the second blocking tumbler which can be freely arranged on any position below the second tumbler groove is arranged in the lock core, the position randomness of the second blocking tumbler during mounting can enable secret key quantity of the lock core to be increased greatly, and time needed by technical opening is greatly prolonged.
Description
Technical field
The utility model relates to a kind of cylinder lock head and key thereof, relates to the lock field.
Background technology
All kinds of blades and billiards lock structure are too single on the existing market, and blade construction is simple, is difficult to watch out for skilled unlocking; The tapered end of commonly using in the market mainly contains two kinds of anti-technology unlocking modes: a kind of S of being groove tapered end, principle are crooked by the S shape of key, hinder unlocking tool and stir pellet, and another kind is to realize the anti-function of dialling by various Special-shaped marbles.S groove tapered end is for the unlocking tool of today, far from technical difficulty; Although Special-shaped marble structure unlocking difficulty has increased, fault rate also increases on year-on-year basis.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned shortcoming that exists for existing tapered end, provide a kind of good anti-theft effect cylinder lock head and key thereof.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of cylinder lock head and key thereof, include lock housing, lock core and key, described lock core is provided with key, described lock core is provided with and vertically arranged the first bullet groove of described key, be provided with the shutoff pellet in described the first bullet groove, also be provided with the vertically arranged blade groove of some and described key in the described lock core, be furnished with blade in the described blade groove, be provided with blade top spring between blade and the blade groove, have the through hole that runs through for key on the described blade, described through hole is provided with towards the inboard projection of extending of through hole, be positioned at the blade groove top in the described lock core and be provided with locating slot, be furnished with a spacer in the locating slot, be provided with the top spring between described spacer and the locating slot, the corresponding spacer of described lock housing position is provided with the first groove that extends for spacer; Described vane tip has the second groove that cooperates with spacer, and the groove depth of described the second groove is greater than the groove depth of the first groove; The lower end of described spacer is provided with the second bullet groove, described lock core correspondence position is provided with the second shutoff pellet, the groove width of described the second bullet groove is greater than the diameter of the second shutoff pellet, described the second shutoff pellet can be arranged in arbitrarily arbitrary position, below of the second bullet groove, the described tartar that cooperates with the second shutoff pellet that is provided with on the key, the described tartar that cooperates with the shutoff pellet is through-hole structure.
Described projection includes projection and lower convexity, and the raised position on each blade is different, and the blade alternative is arranged in the different blade grooves; The described tartar that cooperates with shutoff pellet and blade projection that is provided with on the key, the described tartar that cooperates with the shutoff pellet is through-hole structure.
Described the second bullet groove is between some blade grooves.
Can arrange as required a plurality of blades in the described blade groove.
Operating principle of the present utility model is: no matter unblank or blocking, front end shutoff pellet cooperates with the lock housing gapless, next the second shutoff pellet withstands spacer, stir slightly that lock housing and lock core are automatically locked and the second shutoff pellet withstands spacer, spacer is not able to come under just, double locking, lock core just can't be opened; Key cooperates with blade, and when the second groove of blade was positioned at spacer below one straight line, spacer fell into the second groove of blade, and the unlatching lockset unlocks.During original state, spacer is withstood on by the spacer spring in the first groove of lock housing, the lock core spline; Shutoff pellet and the second shutoff pellet automatically locked when foreign matter inserted.
Compared with prior art, the utlity model has following beneficial effect: 1, the raised position on each blade is different, adopt a plurality of blades to be used in combination, and second a shutoff pellet that can be arranged in arbitrarily arbitrary position below the second bullet groove is set in lock core, the uncertainty of blade during installation, and the randomness of the second shutoff pellet position, the size of key of this lock core is significantly promoted, increased greatly the technical opening required time; 2, the second shutoff pellet double locking structure that arranges in the lock core has fundamentally been stopped the possibility of technical opening and violence unlatching, causes the security performance of lock core to reach ultimate attainment; 3, project organization is scientific and reasonable, unblanks with short-cut method control tinfoil, and Nover practical has greatly been strengthened the theftproof performance of lockset, is fit to promote the use of on all types of security doors.
