Abstract
The utility model relates to an improved lock cylinder mechanism. The improved lock cylinder mechanism comprises a lock cylinder shaft outer sleeve and a lock cylinder shaft, wherein the lock cylinder shaft is movably connected into the lock cylinder shaft outer sleeve in a sleeved mode. A central marble component is arranged in the lock cylinder shaft outer sleeve and the lock cylinder shaft. A security sliding block is arranged at one end of the side portion of the key hole plane of the lock cylinder shaft in a sliding mode. The security sliding block is provided with an extending portion relative to a key hole, and the extending portion forms a pushing portion and enters the key hole. The security sliding block is further provided with an extending portion relative to the inner wall of the lock cylinder shaft outer sleeve, the extending portion forms a locking protrusion, the locking protrusion is matched with an axial groove and an annular groove, and the axial groove and the annular groove cross each other in the inner wall of the lock cylinder shaft outer sleeve. One end of the security sliding block is provided with a reset spring. By means of the improved lock cylinder mechanism, the defect that an existing lock cylinder mechanism is poor in thievery prevention performance is overcome; through the design of the security sliding block, the thievery prevention performance of a lock cylinder is greatly improved; the improved lock cylinder mechanism has the advantages of being high in thumbing resistance, convenient to unlock and operate, low in failure rate and high in reliability.
Description
Technical field
The utility model relates to a kind of improved lock core mechanism.
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 adopt blade 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 lock, 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 improved lock core mechanism, and the antitheft anti-dial performance of this lock core mechanism 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, in lock core shaft's overcoat and lock core shaft, be provided with center pellet member, in lock core shaft, slide safe sliding block be set in sidepiece one end of key hole plane, on safe sliding block, there is the extension with respect to key hole, this extends to form as promotion part and enters in key hole, on safe sliding block, also there is the extension with respect to lock core shaft's outer casing inner wall, this extend to form into lock tab, 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 lock core shaft's overcoat, by jump ring, located, jump ring is provided with spring confinement block, and back-moving spring top is pressed between safe sliding block and spring confinement block.
On safe sliding block, be provided with spring eye, one end of back-moving spring is inserted and is pushed up and is pressed in spring eye.
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.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, detailed content of the present utility model is described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the assembling drawing that the utility model does not insert key state.
Fig. 3 is the assembling drawing that the utility model inserts key state.
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, in lock core shaft's overcoat 1 and lock core shaft 2, be provided with center pellet member, in lock core shaft 2, slide safe sliding block 4 be set in sidepiece one end of key hole 3 planes, on safe sliding block 4, there is the extension with respect to key hole 3, this extends to form as promotion part 5 and enters in key hole 3, on safe sliding block 4, also there is the extension with respect to lock core shaft's overcoat 1 inwall, this extend to form into lock tab 6, lock tab 6 be arranged on lock core shaft's overcoat 1 inwall on crossing axial groove 7 and annular groove 8 match, one end of safe sliding block 4 is provided with back-moving spring 9.Between lock core shaft 2 and lock core shaft's overcoat 1, by jump ring 10, located, jump ring 10 is provided with spring confinement block 11, and back-moving spring 9 tops are pressed between safe sliding block 4 and spring confinement block 11.On safe sliding block 4, be provided with spring eye 12, one end of back-moving spring 9 is inserted and is pushed up and is pressed in spring eye 12.Under the state of the anti-dial tartar mistake of the key 13 inserting, even correct with the close tooth of master that center pellet member matches, safe sliding block 6 still can not be promoted by key, the lock tab 6 of extending on safe sliding block 6 is still in the axial groove 7 on lock core shaft's overcoat 1 inwall, and lock core shaft 2 can not rotate and be in the lock state.When inserting main close tooth and anti-dial tartar all after correct key 13, key 13 promotes by the promotion part 5 of extending on safe sliding block 6 the resistance slippage that safe sliding block 4 overcomes back-moving spring 9, lock tab 6 on safe sliding block 4 vertically groove 7 enters annular groove 8, and key 13 can drive lock core shaft 2 to rotarily open.Above-described embodiment is described the preferred embodiment of a kind of improved lock core mechanism of the utility model; not the design of utility model and scope are limited; do not departing under the prerequisite of 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 improved lock core mechanism of the utility model.
