Description
Technical field
The utility model relates to the password matching mechanism for seedlings of a kind of key, lock core.
Background technology
Traditional key, its side is arranged protruding continuous sheet to unblank close tooth, or in the surperficial code groove arranged on some same axis of key body, when key inserts lock core, one group of password pellet in lockset mates with unblank close tooth phase or code groove on the key, and its cooperation is comparatively coarse, password combination is few, theftproof performance is weak, and stability is not high, and feel of unblanking is poor.
Summary of the invention
In order to the cooperation overcome between traditional keys in prior art, lock core is coarse, password combination is few, theftproof performance is more weak, the problem that feel of unblanking is poor, the utility model provides the password matching mechanism for seedlings of a kind of key, lock core, and the cooperation of the password matching mechanism for seedlings of this key, lock core is compact, and stability is high, the change of password combination is many, and theftproof performance is strong.
The utility model solves the technical scheme that its technical problem adopts: comprise key body and lock core, key body is provided with some settings code groove on the same axis, the password pellet matched with code groove is set in lock core, the flexure strip of fixed lobe on key body, flexure strip is fixed on key body by keeper, the key body relative with flexure strip offers travel grooves, the insurance pellet matched with flexure strip is set in lock core.
Travel grooves and code groove are arranged on the same axis.
Flexure strip is arranged on the rear end of key body, and flexure strip and travel grooves are symmetrical arranged in the two sides of key body, and it is convex that flexure strip is provided with top.
The two sides of key body arrange password elongated slot adjacent to code groove.
The utility model is by above-mentioned specific design, and flexure strip can match with the insurance pellet in lock core, considerably increases the combination change of key cipher, improves theftproof performance, have compact conformation, the unlatching of lock core is stablized, operating handle is good advantage.
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 structure sectional view of the utility model when not inserting key.
Fig. 3 is the structure sectional view after the utility model inserts key.
Detailed description of the invention
As shown in the figure, the utility model comprises key body 1 and lock core 2, key body 1 is provided with some settings code groove 3 on the same axis, the password pellet 4 matched with code groove 3 is set in lock core 2, at the flexure strip 5 of the rear end fixed lobe of key body 1, flexure strip 5 is fixed on key body 1 by keeper 6, keeper 6 can be the securing member of rivet and so on, the key body 1 relative with flexure strip 5 offers travel grooves 7, and travel grooves 7 provides stroke space during flexure strip 5 pressurized.Arrange the insurance pellet 8 matched with flexure strip 5 in lock core 2, insurance pellet 8 is also the part forming key in lock core 2.The optimum design position of travel grooves 7 arranges on the same axis with code groove 3, the technology difficulty of key and lock core manufacture can be reduced, certainly, travel grooves 7 and code groove 3 also can be arranged on different axis, and this can design according to the concrete structure of lock core.Flexure strip 5 and travel grooves 7 are symmetrical arranged in the two sides of key body 1, and flexure strip 5 is provided with top convex 9 like this, and key need not distinguish positive and negative when inserting, and can open, and push up convex 9 be designed with the propelling being beneficial to relative insurance pellet 8.The two sides of key body 1 arrange password elongated slot 10 adjacent to code groove 3, and the design of password elongated slot 10 is the combination changes in order to increase key cipher further, improves theftproof performance.After key inserts lock core, the password pellet that code groove 3, password elongated slot 10 are all relative with in lock core matches, insurance pellet 8 in flexure strip 5 pushing lock cylinder, mating face between the insurance bullet 8 that matches in lock core and tack pellet 11 is flushed with the mating face between lock core 2, lock core sleeve 12, and lock core 2 can be opened by key driven rotary.Above-described embodiment is only be described the preferred embodiment of the password matching mechanism for seedlings of a kind of key of the utility model, lock core; not the design of utility model and scope are limited; under the prerequisite not departing from the utility model scheme; the various external form modification that those skilled in the art make the technical solution of the utility model and improvement, all should fall into the protection domain of password matching mechanism for seedlings of a kind of key of the utility model, lock core.
