Abstract
The utility model relates to a lock cylinder mechanism with a safety function. The key cylinder mechanism comprises a lock cylinder shaft outer sleeve, a lock cylinder shaft and a center pin member, wherein a safety part is arranged at one end of the side of a key insertion hole in the lock cylinder shaft and comprises a joint body fixed on the lock cylinder shaft and a safety sliding block matched with the joint body in a sliding manner, cut-through safety pin holes are formed oppositely in the joint body and the safety sliding block, a spring, a flat-end pin and a pointed-end pin are sequentially arranged in the cut-through safety pin holes, the pointed-end pin and a propulsion part extending from the safety sliding block enter the key insertion hole, an extended locking bulge is arranged on the safety sliding block and matched with an axial groove and a circular groove which are intersected on the inner wall of the lock cylinder shaft outer sleeve, and a reset spring is arranged at one end of the safety sliding block. The lock cylinder mechanism with the safety function overcomes the defect that the conventional lock cylinder mechanism is poorer in anti-theft performance, and has the advantages of strong anti-dialing property, easy unlocking operation, low fault rate and high reliability, and the anti-theft performance of the conventional lock cylinder mechanism is greatly improved.
Description
Technical field
The utility model relates to a kind of lock core mechanism with insurance function.
Background technology
Traditional lock core mechanism of door lock, general upper and lower pellet or the blade of adopting of Cipher mechanism in lock core, wherein the structure design of upper and lower pellet is simpler and cruder, theftproof performance a little less than, and the employing blade is as the lock core of Cipher mechanism, be all that the blade arranged by difference and the groove fit of lock core shaft's overcoat are locked, the theftproof performance of its structure design is not strong yet, and in use procedure, fault rate is higher.
Summary of the invention
The higher problem of fault rate for the theftproof performance that overcomes common lock core mechanism of door lock in prior art is weak, in use procedure, the utility model provides a kind of lock core mechanism with insurance function, and the antitheft anti-dial performance of this lock core mechanism with insurance function is strong, unlock operation convenient, reliability is strong.
The utility model solves the technical scheme that its technical problem adopts: comprise lock core shaft's overcoat and be actively socketed on the lock core shaft in lock core shaft's overcoat, be provided with center pellet member 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 that is fixed in lock core shaft and the safe sliding block be slidably matched with conjugant, at conjugant and the relative insurance marble hole of offering perforation in safe sliding block, install successively spring in the insurance marble hole, tack pellet and tip pellet, the promotion part of extending on tip pellet and safe sliding block enters key hole, also there is the lock tab of extension on safe sliding block, lock tab be arranged on lock core shaft's outer casing inner wall on crossing axial groove and annular groove match, one end of safe sliding block is provided with back-moving spring.
Between lock core shaft and conjugant, outside lock core shaft's overcoat, by jump ring, fixed, the back-moving spring top is pressed between safe sliding block and jump ring.
The utility model, by the design of above-mentioned safe sliding block, has improved the theftproof performance of lock core greatly, has advantages of that anti-dial performance is strong, unlock operation convenience, failure rate is low, reliability be strong.

The specific embodiment
As shown in the figure, the utility model comprises lock core shaft's overcoat 1 and is actively socketed on the lock core shaft 2 in lock core shaft's overcoat 1, be provided with center pellet member 17 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 that is fixed in lock core shaft 2 and the safe sliding block 6 be slidably matched with conjugant 5, at conjugant 5 and the relative insurance marble hole 7 of offering perforation in safe sliding block 6, install successively spring 8 in insurance marble hole 7, tack pellet 9 and tip pellet 10, the promotion part 11 of extending on tip pellet 10 and safe sliding block 6 enters key hole 3, the lock tab 12 that also there is extension on safe sliding block 6, lock tab 12 be arranged on lock core shaft's overcoat 1 inwall on crossing axial groove 13 and annular groove 14 match, one end of safe sliding block 6 is provided with back-moving spring 15, fixing by jump ring 16 outside lock core shaft's overcoat 1 between lock core shaft 2 and conjugant 5, back-moving spring 15 tops are pressed between safe sliding block 6 and jump ring 16.Under the state that does not insert key 18,17 dislocation of center pellet member, simultaneously, the mating face dislocation that the mating face that tack pellet 9 and tip pellet are 10 and conjugant 5, safe sliding block are 6, in the axial groove 13 of lock tab 12 on lock core shaft's overcoat 1 inwall extended on safe sliding block 6, lock core shaft 2 can not rotate and be in the lock state.While inserting key 18, at first center pellet member 17 releases, the mating face that the mating face that then 10 slippages of tip pellet make 10 of tack pellet 9 and tip pellets and conjugant 5, safe sliding block are 6 flushes, then key promotes by the promotion part 11 of extending on safe sliding block 6 the resistance slippage that safe sliding block 6 overcomes back-moving spring 15 again, lock tab 12 on safe sliding block 6 groove 13 vertically enters annular groove 14, and key can drive lock core shaft 2 and rotarily open.Above-described embodiment is only that the preferred embodiment to a kind of lock core mechanism with insurance function of the utility model is described; not design and the scope of utility model are limited; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model, all should fall into the protection domain of a kind of lock core mechanism with insurance function of the utility model.
