Abstract
The utility model discloses an anti-technology opening zigzag groove pin tumbler lock core. The lock core is connected with a transmission part and a thumb wheel. Steel nails are separately inserted in two ends of the lock. The positions of the steel nails are corresponding to the positions of pins. The inside of the lock core is additionally provided with a pin with a T-shaped lateral surface and additionally provided with an anti-rotary transverse sheath. The arrangement of the steel nails has anti-drill function, and therefore, the pin in the lock core can be protected. The added T-shaped lateral surface pin can lead to the failure of the technology opening, and at the same time, because of the increase of the pin number, the mutual opening rate is decreased in geometric series. The cryptographic-key amount can reach above 15,000,000, and the anti-theft performance has reached to the B-level standard of public security department. The zigzag groove on the lock is randomly generated by a computer, and the possibility of the copying of the lock on the street is prevented. The anti-rotary transverse sheath in the lock core is a steel flat key. When the lock core is enforced to be rotated, the lock core and the lock casing can be deadly locked, preventing violent unlocking. In order to prevent the breakdown of the key, 2.8mm copper plate is used to increase the bearing capacity of the key.
Description
Technical field
The utility model relates to a kind of lock core, specifically a kind of anti-technical opening snakelike tank lock cylinder.
Background technology
Existing lock, family expenses door lock particularly, more and more has safety, because all descended the very big time on the problem that its mutual unlocking rate and anti-violence are unblanked, but at present on the structure with regard to lock core, still there is unsafe defective, such as destroying inner pellet shot from a slingshot with the saturating lock core of bit drills, use skilled unlocking for another example, unlocking rate is still bigger, also unblanks such as enforceable rotational lock core realization violence, and the key of corresponding lock core is because the groove of offering above is simple linear pattern, the imitation bitting of stall with goods spread out on the ground for sale, curbside is easy to, and also is a potential safety hazard.On the problem that key ruptures easily, also need to improve simultaneously.The utility model all improves at above-mentioned defective.
The utility model content
Technical problem to be solved of the present utility model is at the prior art weak point, and a kind of anti-technical opening snakelike tank lock cylinder is provided, and mutual opening rate is low, prevented that effectively violence from unblanking.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-technical opening snakelike tank lock cylinder, and described lock core is connected with thumb wheel with driving member, and the lock housing two ends respectively are bumped into a steel nail; What described lock core one side was used is double reinforcement pellet shot from a slingshot; The position of its steel nail and the position of pellet shot from a slingshot adapt; Be equipped with T shape side tumbler in the described lock core, described T shape side tumbler is arranged on a side of original round sides pellet shot from a slingshot.
One side of the T shape side tumbler in the described lock core is provided with the anti-rotation lateral pin.
Described anti-rotation lateral pin is the steel flat key.
T shape side tumbler in the described lock core is complementary with the snakelike tank that matches on the key, drives the action of T shape side tumbler during the plug key.
A kind of anti-technical opening snakelike tank lock cylinder of the present utility model is compared with prior art, has following beneficial effect:
The utility model lock housing two ends respectively are bumped into steel nail, make sharp devices such as drill bit be difficult for piercing, thus protection lock in-core portion pellet shot from a slingshot.Increasing T shape side tumbler newly has a certain degree with original circular pellet shot from a slingshot, technical unlocking almost can not be realized, simultaneously because the increase of marble amount, make mutual opening rate become geometric progression to reduce, this lock core is broken the primitive technology door lock, and this lock core has used double reinforcement pellet shot from a slingshot, thereby has increased its size of key, to have reached more than 1,500 ten thousand, theftproof performance has reached the B of public security department grade standard.The flute profile of snake shape generates at random by computer on the key, has stopped the possibility of stall with goods spread out on the ground for sale, curbside imitation bitting.The both sides of the side tumbler in the described lock core are provided with the anti-rotation lateral pin, and the anti-rotation lateral pin is the steel flat key, when forcing the rotation lock inner core, make inner core and lock housing stuck, thereby prevent that violence from unblanking.For preventing the key fracture, use 2.8mm copper, increased its holding capacity, can be used for any inside door and security door.
Description of drawings
Accompanying drawing is a kind of structural representation of anti-technical opening snakelike tank lock cylinder.
Among the figure: 1, lock core; 2, steel nail; 3, anti-rotation lateral pin; 4, T shape side tumbler; 5, driving member; 6, thumb wheel; 7, double reinforcement pellet shot from a slingshot.
The specific embodiment
Next with reference to Figure of description to a kind of anti-technical opening snakelike tank lock cylinder of the present utility model, explain below the work.
A kind of anti-technical opening snakelike tank lock cylinder of the present utility model, described inner key cylinder 1 is connected with thumb wheel 6 with driving member 5, and the lock housing two ends respectively are bumped into a steel nail 2; Drill bit can't be pierced, thus protection lock in-core portion pellet shot from a slingshot.The position of its steel nail and the position of pellet shot from a slingshot adapt; What described lock core one side was used is double reinforcement pellet shot from a slingshot 7; Be equipped with T shape side tumbler 4 in the described lock core, described side tumbler is arranged on a side of original pellet shot from a slingshot.Increase side tumbler newly and have a certain degree with original circular pellet shot from a slingshot, technical unlocking almost can not be realized, because the increase of marble amount makes mutual opening rate become geometric progression to reduce, this product key amount can reach more than 1,500 ten thousand simultaneously.The flute profile of snake shape generates at random by computer on the key, has stopped the possibility of stall with goods spread out on the ground for sale, curbside imitation bitting.
The both sides of the side tumbler in the described lock core are provided with anti-rotation lateral pin 3.Described anti-rotation lateral pin is the steel flat key.When forcing the rotation lock inner core, make inner core and lock housing stuck, thereby prevent that violence from unblanking.
For preventing the key fracture, use the 2.8mm copper coin, increased its holding capacity, can be used for any inside door and security door.T shape side tumbler in the described lock core is complementary with the snakelike tank that matches on the key, drives the action of T shape side tumbler during the plug key.This product main feature is exactly that the interior pellet shot from a slingshot of lock core moves snakelike tank on the valid key mutually.
