Abstract
The invention relates to a lock cylinder mechanism with a safety protecting function, which comprises a lock cylinder shaft outer sleeve, a lock cylinder shaft, and a central latch component, wherein a safety protecting part is arranged at one end at a side part of a key slot in the lock cylinder shaft; the safety protecting part comprises a connecter fixed with the lock cylinder shaft and a safety protecting sliding block matched with the connecter in a sliding manner; communicated safety protecting latch holes are oppositely formed in the connecter and the safety protecting sliding block; springs, flat-end latches, and pointed-end latches are mounted in the safety protecting latch holes in sequence; the pointed-end latches and a pushing part extended on the safety protecting sliding block enter into the key slot; the safety protecting sliding block is also provided with an extended locking convex; the locking convex is matched with an axial groove and a ring groove, which are crossed and formed in an inner wall of the lock cylinder shaft outer sleeve; a return spring is arranged at one end of the safety protecting sliding block. The safety protecting cylinder mechanism overcomes the defect that a conventional lock cylinder mechanism has a weaker anti-theft property, greatly improves the anti-theft property of the lock cylinder, and has the advantages of strong anti-pull property, convenience in unlocking, low failure rate, and high reliability.
Description
Technical field
The present invention relates to a kind of lock core mechanism with insurance function.
Background technology
Traditional lock core mechanism of door lock, Cipher mechanism in lock core generally adopts upper and lower pellet or blade, wherein the structure design of upper and lower pellet is simpler and cruder, theftproof performance is more weak, and adopt blade as the lock core of Cipher mechanism, be all that the groove fit of blade and the lock core shaft's overcoat arranged by difference is locked, the theftproof performance of its structure design is also strong, and in use procedure, fault rate is higher.
Summary of the invention
The problem that fault rate is higher in order to the theftproof performance overcoming common lock core mechanism of door lock in prior art is more weak, in use procedure, the invention provides a kind of lock core mechanism with insurance function, the antitheft anti-dial performance of the lock core mechanism of this band insurance function is strong, unlock operation is convenient, reliability is strong.
The technical solution adopted for the present invention to solve the technical problems is: comprise lock core shaft's overcoat and be actively socketed on the lock core shaft in lock core shaft's overcoat, center pellet component is provided with in lock core shaft's overcoat and lock core shaft, in lock core shaft, sidepiece one end of key hole arranges insurance division, insurance division comprises the conjugant being fixed on lock core shaft and the safe sliding block be slidably matched with conjugant, relatively in conjugant with safe sliding block offer through insurance marble hole, spring is installed successively in insurance marble hole, tack pellet and tip pellet, the promotion part that tip pellet and safe sliding block extend enters key hole, safe sliding block also has the lock tab of extension, lock tab be arranged on axial groove crossing on lock core shaft's outer casing inner wall and annular groove matches, one end of safe sliding block is provided with back-moving spring.
Fixed by jump ring outside lock core shaft's overcoat between lock core shaft and conjugant, back-moving spring top is pressed between safe sliding block and jump ring.
The present invention, by the design of above-mentioned safe sliding block, substantially increases the theftproof performance of lock core, have that anti-dial performance is strong, unlock operation convenience, failure rate is low, advantage that reliability is strong.

Detailed description of the invention
As shown in the figure, the lock core shaft 2 that the present invention includes lock core shaft's overcoat 1 and be actively socketed in lock core shaft's overcoat 1, center pellet component 17 is provided with in lock core shaft's overcoat 1 and lock core shaft 2, in lock core shaft 2, sidepiece one end of key hole 3 arranges insurance division 4, insurance division 4 comprises the conjugant 5 being fixed on lock core shaft 2 and the safe sliding block 6 be slidably matched with conjugant 5, relatively in conjugant 5 with safe sliding block 6 offer through insurance marble hole 7, spring 8 is installed successively in insurance marble hole 7, tack pellet 9 and tip pellet 10, the promotion part 11 that tip pellet 10 and safe sliding block 6 extend enters key hole 3, safe sliding block 6 also has the lock tab 12 of extension, lock tab 12 be arranged on axial groove 13 crossing on lock core shaft's overcoat 1 inwall and annular groove 14 matches, one end of safe sliding block 6 is provided with back-moving spring 15, fixed by jump ring 16 outside lock core shaft's overcoat 1 between lock core shaft 2 and conjugant 5, back-moving spring 15 top is pressed between safe sliding block 6 and jump ring 16.Under the state not inserting key 18, center pellet component 17 misplaces, simultaneously, mating face between the mating face between tack pellet 9 and tip pellet 10 and conjugant 5, safe sliding block 6 misplaces, the lock tab 12 that safe sliding block 6 extends is in the axial groove 13 on lock core shaft's overcoat 1 inwall, and lock core shaft 2 can not rotate and be in the lock state.When inserting key 18, first center pellet component 17 unlocks, then tip pellet 10 slippage makes the mating face between tack pellet 9 and tip pellet 10 flush with the mating face between conjugant 5, safe sliding block 6, then key promotes by the promotion part 11 that safe sliding block 6 extends the resistance slippage that safe sliding block 6 overcomes back-moving spring 15 again, lock tab 12 on safe sliding block 6 vertically groove 13 enters annular groove 14, and key can drive lock core shaft 2 to rotarily open.Above-described embodiment is only be described the preferred embodiment of a kind of lock core mechanism with insurance function of the present invention; not the design of inventing and scope are limited; under the prerequisite not departing from the present invention program; the various external form modification that those skilled in the art make technical scheme of the present invention and improvement, all should fall into the protection domain of a kind of lock core mechanism with insurance function of the present invention.
