Among Fig. 1-Figure 16, lock pin driving lever sheet (1), outer lock core (2), internal cylinder (3), jump ring (4), outer lock core (5), draw-in groove (6), lock body (7), hoodle (8), hoodle (9), spring (10), lead sealing (11), hoodle (12), hoodle (13), hoodle (14), key slot (15), key (16), jump ring groove (17), hoodle hole (18), hoodle hole (19), hoodle hole (20), hoodle hole (21), hoodle hole (22), hoodle hole (23), sliding pin stop block (24), outer lock core hoodle hole (25), outer lock core hoodle hole (26), outer lock core hoodle hole (27), sliding pin stop block (29), lock body hoodle hole (30), lock body hoodle hole (31), hoodle hole (32), sliding pin hole (33), dress lock core lock body opening (34).

The specific embodiment

Most preferred embodiment of the present utility model is such, with reference to Fig. 1-Figure 16, mainly combine by internal cylinder (3), outer lock core (2), lock body (7), the three links fixing by sliding pin stop block (24,29) draw-in grooves (6), jump ring (4), lock body (7), outer lock core (2), internal cylinder (3) add three grades of hoodles (interior, in, outer) (8,9,12), spring (10) respectively, carry out the theftproof lock of the multilayer hoodle twin-lock core that lead sealing (11) forms at last in outside, lock body (7) hoodle hole.

The utility model is installed and used principle: enter lockup state when pushing key (16) lock core aside, hoodle (8,9,12) internal cylinder that do not coexist, on the contact surface of outer lock core and lock body, hoodle carries out three's binding and locks, when inserting key, the contact surface of hoodle contact surface and outer lock core (2) lock body (7) coexists always on the money, and the contact surface of interior hoodle is not on the contact surface of internal cylinder (3) and outer lock core (2), rotate in key (16) drive, outer lock core, reach the purpose of unblanking, because two-layer lock core and multilayer hoodle are arranged, thereby confused to utilize and chosen the track (, just can not open) that hoodle is unblanked as long as one group of hoodle difference is arranged on the contact surface of outer lock core and lock body.When destroying hoodle by force and unblank, the moment of internal cylinder and outer lock core contact surface is shorter than the moment of outer lock core and lock body, and according to lever principle, the hoodle between internal cylinder and the outer lock core is fracture earlier, prevents to rotate outer lock core, reaches antitheft purpose.It is such that its concrete structure constitutes, dress outer lock core (2) in the lock body (7), internal cylinder (3), hoodle (12,13,14), spring (10) is contained in outer lock core (2), internal cylinder (3), outer lock core (5) is to the hoodle hole (18 of lock body (7), 19,20) and hoodle hole (21,22,23) lining, and then be spring (10), spring (10) is outer to be lead sealing (11), lock pin driving lever sheet (1) is arranged under the outer lock core (2), key slot (15) is arranged in the middle of the internal cylinder (3), key slot (15) inserts key (16), internal cylinder (3), outer lock core (2), outer lock core (5) is contained in dress lock core lock body opening (34) lining of lock body (7), internal cylinder (3), outer lock core (2), the body body portion direction of lock body (7) has hoodle hole (18,19,20) and hoodle hole (21,22,23) and outer lock core hoodle hole (25,26,27) lock body hoodle hole (30,31,32), draw-in groove (6) is arranged at outer lock core (2) bottom, external diameter has sliding pin stop block (24,29), sliding pin hole (33) dress sliding pin is arranged at lock body (7) bottom, and the centre has interior counterbore dress lock core lock body opening (34) dress lock core to use.Technical pattern of the present utility model install by lock body (7) add inside and outside two lock cores (2,3) and more than three layers pellet shot from a slingshot form, lock pin driving lever sheet (1) is connected on the outer lock core.The outer lock core (5) of just in lock body (7), packing into, the internal cylinder (3) of in outer lock core (2), packing into again, establish hoodle hole (18 with outer lock core (2) to internal cylinder (3) by lock body (7), 19,20,21,22,23,25,26,27,29,30,31), many the hoodles (8 of packing into, 9,12,13,14), in off position down, hoodle locking lock body (7) and outer lock core (2) and internal cylinder (3), make inside and outside two lock cores (2,3) can't rotate, when adaptive key (16) inserts, open the hoodle of lock body (7) and outer lock core (2), continue to close the hoodle of outer lock core (2) and internal cylinder (3) simultaneously, twisting key (16), make inside and outside two lock cores (2,3) rotate simultaneously, reach and open lock.

If the robber inserts lockhole with the hard steel sheet, when thinking to turn on by force lock, because lever principle, the robber also can only twist off the hoodle between outer lock core and the internal cylinder, internal cylinder can be rotated, but lock pin driving lever sheet is connected on the outer lock core, open the lock purpose so can't reach, perhaps the robber wants to unblank with the way of instrument jack-up pellet shot from a slingshot, because the not enough position of lock body shell hole, so can't all push up pellet shot from a slingshot in the lock body, lock body and outer lock core are broken away from and the twisting outer lock core is unblanked, also can't be when the every row's pellet shot from a slingshot of jack-up owing to have multilayer pellet shot from a slingshot and two-layer lock core, specialty to unblank master, feel it is which time pellet shot from a slingshot is beated and is to separate lock body and outer lock core, so that the utility model lock compares all in the market locksets is all antitheft actually, insurance.
