Abstract

The utility model discloses a steel ball atomic lock, which comprises a lock core sleeve 2, a lock core 6, a marble 5 with positioning, and a spring 7, wherein the marble 5 with positioning and the spring 7 are arranged in a positioning slot of the lock core 6. The utility model is characterized in that on an inner radial plane, the lock core 6 is provided with a card 4 of which both ends are respectively provided with a card spring 9 which can enable the card 4 to move towards the outside of the lock core 6; a locking steel ball 3 is inlaid between the lock core sleeve 2 and the lock core 6 and is positioned in the outer margin of the card 4; the marble 5 with positioning is provided with a card slot 12 which can enable the card 4 to enter the marble 5 with positioning. The steel ball atomic lock of the utility model has the advantages of favorable reliability, high strength, safety and practicality.

Description

The steel ball Atom lock

Technical field

The utility model relates to a kind of tapered end, particularly relates to a kind of steel ball Atom lock.

Background technology

The existing pellet shot from a slingshot class lock that generally uses, its structure adopts the diverse location state of cylindrical billiard in the pellet shot from a slingshot hole of length different designs to reach locking and purpose of opening.Under normal condition, when unblanking with original key, key inserts lock core pushing tow pellet shot from a slingshot, make down the upper end face of row's pellet shot from a slingshot all equal with the lock core cylindrical outer surface, the rotation of key just can make lock core in the lock core hole of lock body, drive under row's pellet shot from a slingshot rotate synchronously about doing, and stir dead bolt by driver blade and open lock (also can directly drive simultaneously and open lock) by lock core.But the words that this lock is opened as if the universal inserted sheet spoon of being made up of last inserted sheet and following inserted sheet with a group, energy pushing tow pellet shot from a slingshot and energy will be arranged pellet shot from a slingshot down and all eject lock core equally, make down the lower end external surface of row's pellet shot from a slingshot equal with the lock core cylindrical outer surface, lock core can be opened lock relative to arbitrarily rotating about row's pellet shot from a slingshot work down equally so, such lock, concerning omnipotent inserted sheet spoon,, brought serious potential safety hazard to unit and personal property as illusory.

The utility model content

For the defective that overcomes prior art provides a kind of anti-theft lock end that can prevent the high security that omnipotent inserted sheet spoon is opened, the utility model by the following technical solutions:

The steel ball Atom lock, comprise the lock core cover, lock core, the pellet shot from a slingshot and the spring that have the location, have in the pellet shot from a slingshot of location and the locating slot that spring is installed in lock core, lock core inner radial plane is provided with a card, the card spring is equipped with at the card two ends, the card spring promotes card outside lock core, be embedded with locking steelball between lock core cover and the lock core, locking steelball is in the card outer, can be installed in the card outer on, half falls within locking steelball in the lock core, half is in the lock core cover, but have the card slot that has to allow card enter to have the pellet shot from a slingshot of location on the pellet shot from a slingshot of location, the degree of depth of card slot guarantees that locking steelball can all enter in the lock core when card enters card slot.

One or more false grooves also can be arranged having on the pellet shot from a slingshot of location, false groove depth is less than the degree of depth of card slot, when card enters false groove, locking steelball can not all enter lock core and have part to be positioned at the lock core cover, thereby blocking lock core can not do relative motion with the lock core cover, can mislead unnormal unlocking and technical unlocking, improve security protection.

The utility model steel ball Atom lock good reliability, intensity height, safer practicality.

The specific embodiment

Further specify the utility model below in conjunction with accompanying drawing, but be not used for limiting protection domain of the present utility model.

The steel ball Atom lock, comprise lock core cover 2, lock core 6, the pellet shot from a slingshot 5 and the spring 7 that have the location, the pellet shot from a slingshot 5 and the spring 7 that have the location are installed in the locating slot of lock core 6, lock core 6 inner radial planes are provided with a card 4, card spring 9 is equipped with at card 4 two ends, card spring 9 promotes card 4 outside lock core 6, be embedded with locking steelball 3 between lock core cover 2 and the lock core 6, locking steelball 3 is installed on the card 4, half falls within locking steelball 3 in the lock core 6, half is in the lock core cover 2, but have the card slot 12 that a pellet shot from a slingshot 5 that allows card 4 enter to have the location is arranged on the pellet shot from a slingshot 5 of location, the degree of depth of card slot 12 guarantees that locking steelball 3 can all enter in the lock core 6 when card 4 enters card slot 12.

On the pellet shot from a slingshot 5 that has the location, also be provided with more than one false groove 13, can mislead unnormal unlocking and technical unlocking, improve security protection.
