Abstract

The utility model relates to an anti-theft lock core. The technical scheme is as follows: two rows of bullet holes which are mutually staggered to form a right angle are arranged on the lock sleeve, the outer core and the inner core; the outer core is connected with the lock sleeve, the outer core is made into a semi-solid core, the front end of the outer core is provided with a cavity, the solid part is provided with a baffle groove, a key hole and two rows of marble holes which are mutually staggered to form a right angle, and marbles are arranged on the outer core and the lock sleeve at the cavity; an inner core is arranged in the cavity of the outer core, and the wall of the inner core is connected with the inner wall of the outer core; the lock core is provided with a blocking body, a right-angled key hole penetrates through the middle of the inner core, a left-right rotating groove is formed in the outer edge of the inner core along the semi-circumference wall, a front pushing groove and a rear pushing groove are connected to one end of the left-right rotating groove, a marble is movably connected with the left-right rotating groove and the front pushing groove and the rear pushing groove, and when the lock core is in a locking state, the key hole and the key hole are mutually staggered and are 180-degree back to each other. The utility model discloses the key hole of outer core and inner core is staggered each other, has the fender body to block again, so can not carry out the technique and open, increase the theftproof function.

Description

Anti-theft lock

Technical field:

The utility model relates to a kind of lock core, particularly a kind of anti-theft lock.

Background technology:

At present, the anti-theft lock kind is a lot, as the IC-card type, and finger pattern or the like, but price is more expensive, and universal very difficult, and along with development of science and technology is also easily penetrated.Automatic alarm lock is also arranged, also just alarm actuating contact is installed in mechanical lock, when technology opens, will report to the police, but also door can be opened simultaneously in case run into the contact, as on every side nobody the time, also can cause damage to resident family; For mechanical lock, all pellets shot from a slingshot all are visible, make technical opening easy in addition.

Summary of the invention:

In order to address the above problem, the utility model provides a kind of anti-theft lock that has invisible billiards, prevents technical opening.

The technical solution adopted in the utility model is: anti-theft lock is characterized in that comprising that lock tube (1), outer core (2), inner core (3), keyhole (4), block body groove (5), pellet shot from a slingshot hole (6), keyhole (7), left-right rotation groove (8), front and back advance groove (9), pellet shot from a slingshot hole (10) and block body (11); On lock tube (1), outer core (2) and inner core (3), have two to arrange the rectangular pellet shot from a slingshot hole (10) of staggering mutually; Outer core (2) is connected with lock tube (1), outer core (2) is made semisolid, its front end has a cavity, at solid section a block body groove (5), keyhole (4) and the two rows rectangular pellet shot from a slingshot hole (6) of staggering is mutually arranged, and on the outer core (2) at cavity place and lock tube (1) pellet shot from a slingshot (12) is arranged; Inner core (3) is installed in the cavity of core (2) outside, the wall of inner core (3) is connected with outer core (2) inwall, inner core (3) one ends are provided with block body (11), the centre of inner core (3) is penetrated with rectangular keyhole (7), the outer rim of inner core (3) has left-right rotation groove (8) along the semicircle perisporium, before and after being connected with, one end of left-right rotation groove (8) advances groove (9), and left-right rotation groove (8) and front and back advance grooves (9) to have the gradient to be connected, about advance the degree of depth of groove (8) to advance the degree of depth of groove (9) less than front and back; Pellet shot from a slingshot (12) and left-right rotation groove (8) and front and back advance grooves (9) flexible connection, and during the lock core locking state, keyhole (4) and keyhole (7) stagger mutually, become 180 ° opposing.

Operating principle of the present utility model is: when normal unlatching, key inserts in the keyhole, 180 ° of rotation inner cores, it is pellet shot from a slingshot in the left-right rotation groove movable 180 °, when pellet shot from a slingshot arrives the other end of left-right rotation groove, block, block body on the inner core is corresponding with block body groove on the outer core, pellet shot from a slingshot moves in front and back advance groove, when inner core is pushed ahead, in the block body groove on the outer core of block body insertion, keyhole on the while inner core is corresponding with the keyhole on the outer core, in the keyhole on the outer core of key insertion, rotate outer core, door is opened.

The beneficial effects of the utility model are: because keyhole on the inner core and the keyhole on the outer core stagger, become 180 ° opposing, beyond pellet shot from a slingshot on the core be invisible, have only inner core Rotate 180 ° could be inserted key in the keyhole on the outer core, even therefore all be in the pellet shot from a slingshot on the inner core on the active face, inner core can rotate, because the effect of block body still can not be opened door.Stagger mutually and become 90 ° on the inner core two row pellet shot from a slingshot hole in addition, keyhole is blocked, so technology is when opening, and at first solves ° unusual difficulty of inner core Rotate 180, and the increase technology opens difficulty.

The specific embodiment:

Embodiment 1

Anti-theft lock comprises that lock tube 1, outer core 2, inner core 3, keyhole 4, block body groove 5, pellet shot from a slingshot hole 6, keyhole 7, left-right rotation groove 8, front and back advance groove 9, pellet shot from a slingshot hole 10, block body 11 and pellet shot from a slingshot 12;

Shown in Fig. 1～4, on lock tube 1, outer core 2 and inner core 3, have two to arrange the rectangular pellet shot from a slingshot hole 10 of staggering mutually; Outer core 2 is connected with lock tube 1, and outer core 2 is made semisolid, and its front end has a cavity, at solid section a block body groove 5, keyhole 4 and the two rows rectangular pellet shot from a slingshot hole 6 of staggering is mutually arranged, and on the outer core 2 at cavity place and lock tube 1 pellet shot from a slingshot 12 is arranged; Inner core 3 is installed in the cavity of core 2 outside, the wall of inner core 3 is connected with outer core 2 inwalls, inner core 3 one ends are provided with block body 11, the centre of inner core 3 is penetrated with rectangular keyhole 7, the outer rim of inner core 3 has left-right rotation groove 8 along the semicircle perisporium, advance groove 9 before and after one end of left-right rotation groove 8 is connected with, and left-right rotation groove 8 advances groove 9 to have the gradient to be connected with front and back, about advance the degree of depth of the degree of depth of groove 8 less than front and back propelling groove 9; Pellet shot from a slingshot 12 advances groove 9 to flexibly connect with left-right rotation groove 8 and front and back, and during the lock core locking state, keyhole 4 and keyhole 7 stagger mutually, become 180 ° opposing.

During normal the unlatching, key inserts in the keyhole 4, rotates inner core 3, and pellet shot from a slingshot 12 relatively moves in left-right rotation groove 8, when arriving the other end, move forward and backward in front and back advance groove 9, inner core 3 outside cores 2 move, and block body 11 is corresponding with block body groove 5, insert in the block body groove 5, key inserts in the keyhole 7 simultaneously, and 6 pellet shot from a slingshot rotates outer core in the promotion pellet shot from a slingshot hole, and door is opened.

And during improper unlatching,, having block body 5 to stop again because

keyhole

4 and 7 staggers, foreign matters enters in the keyhole 7, thereby door can not be opened.
