Description

Idle running anti-theft lock core and idle running anti-theft lock thereof

Technical field

The utility model relates to a kind of mechanical lock and mechanical lock, especially a kind of idle running anti-theft lock core and idle running anti-theft lock thereof.

Background technology

Existing lockset; No matter it is to use in bicycle, motorcycle or electric motor car, and all kinds of padlock, the handle lock that automobile is used etc.; What use because of it is most is lock cylinder; Use hard instrument brute force to turn round sled so lock core is difficult to keep out the thief, this also is why to steal bicycle, motorcycle or electric motor car at present, even the reason that takes place frequently of vehicle event.In order to address this problem, people have invented the idle running lock, and this lock core is made up of inner core and outer core; Be connected with spring through pellet shot from a slingshot between inner core and the outer core; When the people used correct key unlocking, inner core can advance or retreats to axial direction along outer core, reaches the purpose of normally unblanking; When the people used incorrect key or reverses with other hard instrument brute force, inner core will integral body rotate with outer core, and inner core can not done axially-movable with respect to outer core, thereby just can not unblank.Like the disclosed idle running lock of Chinese patent document CN201460525, be exactly this type, when locking, inner core in axial direction stretches out, and withstands dead bolt, thereby lock is locked; When unblanking, the rotation inner core, inner core is retreated, and under the effect of spring, dead bolt is retreated, thereby unblanks.This idle running lock, though can prevent that the thief from rotating destructiveness and unblanking,, it can not prevent that the thief from axial direction vibrating inner core with other instrument and unblank or inner core is destroyed afterwards and unblanks.

The utility model content

In order to overcome the problems referred to above, the utility model provides a kind of theftproof performance better to society, as long as the lock core of lock dallies, just is difficult to open the idle running anti-theft lock core of this lock again.

The utility model also provides a kind of theftproof performance better idle running anti-theft lock.

The technical scheme of the utility model provides a kind of idle running anti-theft lock core; Comprise lock body, inner core and outer core, said inner core is coaxial to be located at outer in-core, and through axle core perpendicular to inner core in a row be positioned at pellet shot from a slingshot hole pellet shot from a slingshot and spring interconnects; Said outer core is located in the blind hole of said lock body; Outside said, be provided with the segment connected in star on the outer wall of core, in said segment connected in star, be provided with the resistance steel ball, on said resistance steel ball, be provided with the resistance steel ball and spring; One end of resistance steel ball and spring is pressed on the resistance steel ball, and the other end of steel ball and spring is against on the lock body; Outside said on the outer wall of core; Axle core perpendicular to inner core is provided with first and moves steel ball hole; Move said first and to be provided with first in the steel ball hole and to move steel ball; In lock body, be provided with first dead bolt perpendicular to the axle core of inner core, an end of first dead bolt withstands on said first and moves on the steel ball, and the other end of dead bolt is stretched and is being positioned at the latch bolt spring positioning sleeve of lock body; On said first dead bolt, be provided with the first latch bolt spring locating ring, between the said first latch bolt spring positioning sleeve and the first latch bolt spring locating ring, be provided with first latch bolt spring that is enclosed within on first dead bolt; The position that said inner core and said first moves steel ball is provided with first and moves steel ball yielding portion; When locking, first moves steel ball under the effect of inner core, and first moves steel ball is positioned at first fully and moves steel ball hole, and first to move the external surface of steel ball concordant with said outer core outer surface, and said first latch bolt spring is in compressive state; When unblanking, the rotation inner core is right against first when moving steel ball when first of said inner core moves steel ball yielding portion, and under the effect of first latch bolt spring, first moves steel ball and first dead bolt all moves to the shaft core direction of inner core.

As improvement to the utility model, be provided with Lock cylinder cover at the openend of said blind hole, on Lock cylinder cover, be provided with keyhole.

As the improvement to the utility model, the cross section of the key of said inner core is a triangle, and pairing limit, leg-of-mutton each angle is provided with pellet shot from a slingshot hole in a row, in said pellet shot from a slingshot hole, is provided with pellet shot from a slingshot and spring.

As improvement to the utility model; On the outer wall of said inner core near the outer end, be provided with draw-in groove, draw-in groove is over against pairing limit, a leg-of-mutton angle, and communicates with key; Be provided with elastic component at said draw-in groove; On said elastic component, be provided with a protuberance, said protuberance stretches out in key, and the top of protuberance protrudes in the plane at pellet shot from a slingshot place.

As improvement to the utility model; Outside said, on the outer wall of core, be symmetrical in said first and move steel ball hole, also be provided with and second move steel ball hole perpendicular to the axle core of inner core; Move said second and to be provided with second in the steel ball hole and to move steel ball; In lock body 1, be provided with second dead bolt perpendicular to the axle core of inner core, an end of second dead bolt withstands on said second and moves on the steel ball, and the other end of second dead bolt is stretched and is being positioned at the second latch bolt spring positioning sleeve of lock body; On said second dead bolt, be provided with the second latch bolt spring locating ring, between the said second latch bolt spring positioning sleeve and the second latch bolt spring locating ring, be provided with second latch bolt spring that is enclosed within on second dead bolt; The position that said inner core and said second moves steel ball is provided with second and moves steel ball yielding portion; When locking, second moves steel ball under the effect of inner core, and second moves steel ball is positioned at second fully and moves steel ball hole, and second to move the external surface of steel ball concordant with said outer core outer surface, and said second latch bolt spring is in compressive state; When unblanking, the rotation inner core is right against second when moving steel ball when second of said inner core moves steel ball yielding portion, and under the effect of second latch bolt spring, second moves steel ball and second dead bolt all moves to the shaft core direction of inner core.

The utility model also provides a kind of idle running anti-theft lock, includes above-mentioned idle running anti-theft lock core.

The utility model is owing to adopted the bottom surface of lock core to be shut, and promptly lock core (comprising inner core and outer core) is located in the blind hole, and the direction of dead bolt is perpendicular to the axle core of lock core; And when locking; Dead bolt withstands on and moves on the steel ball, and the outside wall surface inner face of the contact surface of dead bolt and mobile steel ball and outer core, like this; The utlity model has following advantage with regard to making: the one, the thief can't unblank from the axial direction of lock core; Because lock core is located in the blind hole, its lock core bottom surface does not have mobile space on axial direction; The 2nd, if lock core produces idle running, as long as promptly one commentaries on classics of outer core, dead bolt will break away from contacted with mobile steel ball; And directly withstand on the external surface of outer core, at this moment, even the thief reaches the pellet shot from a slingshot that is connected with outer core with inner core and destroys fully; Dead bolt also cannot bounce back; Lock is not still opened, and so, has just further improved the theftproof performance of idle running lock.
