Abstract

The utility model relates to a theftproof ball lock and a key, which comprises a lock core casing (1), a lock core body (2) and a locking mechanism. The interior of the high performance theftproof ball lock is provided with two ranks of ball holes (5) which are arranged in parallel and balls (6) with annular grooves (7). The middle position of at one ball (6) of the two ranks of balls (6) is also provided with a theftproof fake groove (8) of which the structure is the same to the structure of each annular groove (7) except being provided with the annular groove (7) for unlocking the lock and at least one ball (6) is made into a conducting magnet ball (9) with conducting magnet materials. The position of a key (10) corresponding to the conducting magnet ball (9) is provided with a magnetic body (11). Because each ball (6) is provided with more than two grooves, the thief does not know which groove is the groove for unlocking the lock or whether the lock is provided with the fake groove (8). In addition, because the ball hole (5) provided with the conducting magnet ball (9) is not communicated with a key jack, the thief can not prize the lock by means of the traditional ball poking mode. The theftproof ball lock and the key have the advantage of high theftproof performance.

Description

A kind of high-performance anti-theft billiards tapered end and key

Technical field: the utility model relates to a kind of anti-theft billiards tapered end and key.

Background technology: in order to improve the theftproof performance of ball lock head, increase opening difficulty, people have designed various anti-theft billiards tapered ends and key, as applying on September 29th, 1999 by Lei Xianming, the patent No. is 99234143.4, name is called the locking device that discloses a kind of ball lock head in " a kind of locking device of cylinder lock ", its architectural feature is that a circle V-type groove is arranged in the middle part of pellet shot from a slingshot, also has locking side column, its inboard is a V-type, can match with the V-type groove on the pellet shot from a slingshot, when the cylinder lock locking, the both sides of locking side column lay respectively in lock core and the lock body, V-type groove and locking side column on the pellet shot from a slingshot stagger, and pellet shot from a slingshot outer wall compressing locking side column makes in its lock core of can not withdrawing, and makes lock core and lock body not to relatively rotate.When unblanking, tartar on the key forces the V-type groove of shift in position on pellet shot from a slingshot of each pellet shot from a slingshot all to overlap, and is on the straight line, at this moment, the V-type inboard of locking side column is slipped in the V-type groove on the pellet shot from a slingshot, and locking side column is withdrawn from lock core shell, and lock core body can rotate relative to lock body.The utility model is owing to adopted the pellet shot from a slingshot of band V-type groove and the locking device that locking side column matches in the cylinder lock, unlocking tool with non-matching key can't make each pellet shot from a slingshot locate simultaneously, and the V-type groove on it is all overlapped, the V-type inboard of locking side column can't be slipped in the V-type groove on the pellet shot from a slingshot, locking side column can not be withdrawn in lock body, event can not be opened lock, thereby has guaranteed the safety and the theftproof of cylinder lock.

Summary of the invention: the purpose of this utility model is to overcoming above-mentioned the deficiencies in the prior art, a kind of high-performance anti-theft billiards tapered end and key are provided, this tapered end relies on sound or feel when stirring pellet shot from a slingshot and the mode that pirate of the open is carried out in the pellet shot from a slingshot location has been increased very big difficulty, or even can't pirate of the open.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of high-performance anti-theft billiards tapered end and key, comprise lock core shell, be arranged at lock core body and locking mechanism in the lock core shell movingly rotationally, described locking mechanism comprises paralleling to the axis and is arranged on the lock core body line of rabbet joint vertical with the pellet shot from a slingshot hole and that be communicated with, the latch recess that is provided with on lock core shell inwall and the described line of rabbet joint opposite position, being arranged at the pellet shot from a slingshot that has annular groove in the pellet shot from a slingshot hole reaches and a sheet locking side column composition that can slide in the passage of the described line of rabbet joint and latch recess formation, annular groove matches on locking side column inboard and the pellet shot from a slingshot, it is characterized in that: be provided with two row pellet shot from a slingshot hole that be arranged in parallel and the pellet shot from a slingshot that has annular groove in described high-performance anti-theft billiards tapered end and the key, have at least in the two row pellets shot from a slingshot on one the middle part of pellet shot from a slingshot except the annular groove that is provided with the usefulness of unblanking, also be provided with the identical antitheft false groove of structure, have at least a pellet shot from a slingshot to make the magnetic conduction pellet shot from a slingshot in the two row pellets shot from a slingshot by permeability magnetic material, the pellet shot from a slingshot hole at described magnetic conduction pellet shot from a slingshot place is not communicated with key hole, and corresponding on the key magnetic conduction pellet shot from a slingshot place is provided with magnetic.

Further setting of the present utility model: except the annular groove that is provided with the usefulness of unblanking, also be provided with the identical antitheft false groove of structure on the described magnetic conduction pellet shot from a slingshot.

Of the present utility modelly further be provided with again: also be provided with one in the described locking mechanism and make locking side column slide to the oblique mechanism of annular groove when making bias force mechanism that locking side column slides to latch recess and a rotation lock core body; Described annular groove sidewall is straight and with the locking side column plane parallel.

Of the present utility modelly further be provided with: described latch recess cross sectional shape is at the bottom of the semi arch or is slightly less than the arcuate bottom groove of semi arch, be provided with cross section and latch recess suitable roller or ball on the locking edge of locking side column rotationally, constitute described oblique mechanism thus; Described bias force mechanism is by the back-moving spring storage chamber that is arranged on line of rabbet joint two ends and be placed in one and the back-moving spring that is in the locking side column below is formed.

Owing on pellet shot from a slingshot, be provided with plural groove, theft does not also know which groove is the real groove or have or not other false groove of unblanking, and has greatly increased opening difficulty, if false groove number reaches a certain amount of, add that true and false groove is crisscross arranged at random, almost can not pirate of the open; In addition, because the pellet shot from a slingshot hole at the pellet shot from a slingshot place of being made by permeability magnetic material is not communicated with key hole, unblank but lean on corresponding on the key pellet shot from a slingshot place of making to be provided with magnetic by permeability magnetic material, can't carry out pirate of the open by traditional mode of stirring pellet shot from a slingshot fully, therefore have higher theftproof performance.

The utility model is described in further detail below in conjunction with accompanying drawing, provides embodiment simultaneously.
