Description
Technical field
The utility model relates to a kind of tapered end of theftproof lock, particularly a kind of pick-proof, the tapered end of anti-pirate of the open and the key that matches with it.
Background technology
Present existing theftproof lock tapered end does not have anything to improve basically, and main improved place is aspect dead bolt, and as increasing the lock point of dead bolt, or the composition that increases some coded locks therein.The tapered end of these theftproof locks all is made up of lock core cover and lock core basically, is provided with 1 group or 4 groups of pellets shot from a slingshot between lock core and the lock core cover.Being provided with 1 group of pellet shot from a slingshot is exactly present more common theftproof lock tapered end, is exactly present Cross lock all the fashion and be provided with 4 groups of pellets shot from a slingshot.No matter be common tapered end, or Cross lock, in use all have some problems like this: 1, the pellet shot from a slingshot in the lock core is squeezed by software materials such as chewing gums easily and opens, and squeezes and opens rear lock core just easily by turn-off, and lock is opened.2, hard thing is inserted in the lock core, firmly rotate, pellet shot from a slingshot is twisted off easily, and is ineffective.3, lock core hole is bored greatly by electric drill easily, and pellet shot from a slingshot drops out, and makes lock core ineffective.4, lock core hole is plugged easily, makes troubles to owner.
Summary of the invention
One of goal of the invention of the present utility model provides a kind of have antitheft, pick-proof, anti-blocking, the pick-proof of anti-drilling function, the tapered end of anti-pirate of the open, to solve many weak points that existing theftproof lock tapered end exists.
One of foregoing invention purpose realizes by following technical measures: the tapered end of a kind of pick-proof, anti-pirate of the open comprises lock core cover, lock core, dead bolt actuator and is installed in pellet shot from a slingshot group between lock core cover and the lock core; It is characterized in that also comprising spacer spring; Lock core, spacer spring and dead bolt driving member from top to bottom are stuck in lock core cover jump ring bottom by one successively and are installed in the lock core cover; Described lock core is made of the lock core piece more than two at least, and there is a pin hole at the center that crosses between the lock core piece; Be provided with a key pin-and-hole on every lock core piece, the bottom is provided with a bolt; Between the hole wall of the key pin-and-hole of every lock core piece and lock core cover, be provided with the pellet shot from a slingshot group; On the dead bolt driving member, have the corresponding bolt of the bolt hole of at least more than one and every lock core piece bottom.
Cover is housed in described key pin-and-hole in one, has one at a side of interior cover and hold the pellet shot from a slingshot group and stretch into rectangular breach in the key pin-and-hole.
One of foregoing invention purpose can also realize by following prioritization scheme: the lock core piece that described lock core is a semicircle type by two cross sections is formed.
Every pellet shot from a slingshot of described pellet shot from a slingshot group can adopt trapezoidal garden pin pellet shot from a slingshot, and the lock core piece is opened the pellet shot from a slingshot hole and also is post hole, trapezoidal garden.
The bolt of every lock core piece bottom can be distributed on the same circumference; Also can stragglyly arrange; Decide according to the quantity and the position of bolt the quantity in bolt hole and position on the dead bolt driving member.
Key pin-and-hole on every lock core piece can be distributed on the same circumference, also can stragglyly arrange.
Two of the present utility model purpose provides the key that a kind of and above-mentioned tapered end matches and uses.
Two of foregoing invention purpose realizes by following technical measures: a kind of key, it is characterized in that comprising the shank of the key, and be provided with the latch that is connected as a single entity with the shank of the key and the key pin more than at least two in the lower central of the shank of the key.
Key pin more than two can be distributed on the same circumference, also can stragglyly arrange.
Owing to adopted design scheme as above, have only to open to press down, and when making the bolt of lock core bottom be inserted in the bolt hole on the dead bolt driving member, lock core could drive dead bolt driving member rotating opening and lock when lock core.If the bolt of lock core bottom is not inserted in the bolt hole on the dead bolt driving member, lock core can only dally, and lock can not be opened.When robber's picking lock, because lock core is to adopt sectional type, if therefrom prize on the mind-set both sides, the lock core piece can squeeze to the outside and hold, and the power of sled is big more, will be tight more between lock core piece and the lock core cover, and make lock core be difficult to more rotate.If prize to the center from the outside, the lock core piece can staple together, and also is not easy to unblank.If hand one pine, spacer spring will be with on the lock core piece jack-up automatic locking.Even top lock core is pried open, the dead bolt tumbler below yet being difficult to rotate is not driven lock too.Pellet shot from a slingshot of the present utility model adopts trapezoidal garden pin pellet shot from a slingshot.Even be positioned at like this pellet shot from a slingshot of key pin-and-hole drilled disconnected after, one section of the back can not drop out yet, make lock core be in the state of locking equally.Adopt at least two key pin-and-holes, the pirate of the open rate is reduced greatly.The utility model is equipped with cover in the key pin-and-hole, if there is foreign matter to enter in the key pin-and-hole, interior cover can be taken out, and outwells foreign matter, has avoided changing the trouble of lock.The utility model is compared with the tapered end of existing theftproof lock in a word, has that anti-pirate of the open rate is low, a pick-proof, anti-blocking, anti-drilling advantage, and simple in structure, low cost of manufacture.
