Description

A kind of anti-bump key lock core
Technical field
The present invention relates to field of lockset, specifically relate to a kind of lock core that prevents and hit the stolen lock core of opening of spoon bump back lock.
Background technology
Popular in the world now method for unlocking is a lot, has: drill bit unblanks, pulls out that the zip core is unblanked, picklock is unblanked etc. is a variety of.And anti-unlocking technique is also a variety of along with having occurred: pick-proof lock core, Anti-drilling lockwork, anti-lock core and the shatter-resistant lock core etc. of pulling out.The patent No. is, 200720106992.1, and name is called, and " the anti-lock core that pulls out of a kind of Prying-resistant and drilling-resistant " patented technology is set up defences at head place, lock core two ends on the basis of establishing I-shaped pick-proof pellet shot from a slingshot and anti-drilling pellet shot from a slingshot, this Prying-resistant and drilling-resistant of anti-drill pin and is bored the anti-iron plate that pulls out.Anti-drilling anti-pull out iron plate with brill, the instrument of pulling out of stealer refuse outside lock core keyhole, further strengthened anti-drilling function, guaranteed anti-realization of pulling out function, really become the Three-protecting lock core.
In recent years popular in the world usefulness is hit spoon (English is Bump key) and is unblanked, and claims " 999 " key unlocking again.Its principle is that the teeth with key reach maximum, and after hitting spoon and inserting keyhole, the following pellet shot from a slingshot in the lock core inner core all can be run into the root that hits the key bit tooth.Thereafter, hit a spoon rear portion.At this moment, because the principle of active force and reaction force is hit spoon with the pellet shot from a slingshot hole in the knocking-on lock core inner core of the last pellet shot from a slingshot in the lock core inner core pellet shot from a slingshot, and then rotational lock core, reach the purpose of opening mechanical cylinder lock.This key has is called MASTERKRY.For preventing to have things stolen, people have noted studying how to tackle the way that MASTERKRY is surreptitiously opened.The patent No. is, 200720192213.4 are called, and the patented technology of " anti-bump key lock core " has at least in every row's lock core inner core pellet shot from a slingshot hole and places a crashproof spoon pellet shot from a slingshot in the row lock core inner core pellet shot from a slingshot hole.Crashproof spoon pellet shot from a slingshot is suspended in the lock core inner core pellet shot from a slingshot hole, and the upper edge of crashproof spoon pellet shot from a slingshot is lower than lock core inner core plane, and its lower edge is higher than bottom, lock core inner core pellet shot from a slingshot hole.When bump hits spoon, the teeth of hitting spoon can only strike the common down pellet shot from a slingshot in the lock core inner core, and bump is less than crashproof spoon pellet shot from a slingshot, crashproof spoon pellet shot from a slingshot relative last pellet shot from a slingshot can not eject lock core inner core pellet shot from a slingshot hole and still be stuck between lock core inner core pellet shot from a slingshot hole and the lock core body pellet shot from a slingshot hole, whole lock core still can not opened, played preventing to hit the effect that spoon is surreptitiously opened, guaranteed safety.And patent No. application is, 200910101596.3 (open) name is called, the technology of " a kind of crashproof strong knocking lock pin ", on the basis of above-mentioned patent, in the lock core inner core pellet shot from a slingshot hole in pellet shot from a slingshot hole, be provided with in that row lock core body pellet shot from a slingshot hole of crashproof spoon pellet shot from a slingshot, under spring, be provided with a cylindrical thin type pellet shot from a slingshot again.When hitting with sudden force spoon, the teeth of hitting spoon only strike common pellet shot from a slingshot down, hit less than crashproof spoon pellet shot from a slingshot.Again because of the effect of cylindrical thin type pellet shot from a slingshot, crashproof spoon pellet shot from a slingshot relative last pellet shot from a slingshot more can not eject lock core inner core pellet shot from a slingshot hole and make pellet shot from a slingshot still be stuck in (between lock core inner core pellet shot from a slingshot hole and the lock core body pellet shot from a slingshot hole) between the upper and lower pellet shot from a slingshot hole, make lock core be not easy more to be opened and guaranteed safety.
But also there are some defectives in existing anti-bump key lock core, as: crashproof spoon pellet shot from a slingshot and cylindrical thin type pellet shot from a slingshot are set, make the product structure more complicated, assemble also more time-consuming.It is higher in addition the component of product to be made required precision, causes cost also to increase thereupon.
