Description

A kind of indirect control spoon lockset and matched key

Technical field

The utility model relates to a kind of theft-proof door lock structure, particularly a kind of lockset of indirect control key and matched key thereof.

Background technology

At present, general lockset on market can see through keyhole and directly touch lock core, and lock core is the heart of a secondary lock tool, and the keyhole that unlocking technique personnel utilize special tool to see through lockset is holed to lock core or turns round by force, just can to lockset, damage easily, thereby realize, unblank.The leak of these locksets, as accidentally utilized by robber, makes our potential safety hazard increasing at one's side undoubtedly, even can cause economic loss to user.And existing indirect lock-fit-type lock structure is complicated on the market, handling poor, often to user, make troubles.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of lockset and matched key of indirect control key.

The technical scheme that the utility model adopts is:

A kind of indirect control spoon lockset, comprise Protective lock cover, lock core and lock body, it is characterized in that described lock core, lock body front portion is provided with Protective lock cover, in described Protective lock cover, be provided with cylinder, on described cylinder, have key notch, described cylinder can rotate, described cylinder is connected with gear fixture by cylinder fixed axis, described key shank control gear and handgrip driven wheel are meshing to be arranged on gear fixture, on described Protective lock cover, control handgrip is installed, described control handgrip is connected with handgrip driving gear drives by handgrip driving shaft, described key shank control gear offers respectively the intercommunicating pore that can be connected with described lock core with gear fixture, described lock core is arranged in lock body.

Described Protective lock cover offer with described cylinder on the key mouth of key notch conducting, the cambered surface of described cylinder and Protective lock cover leave gap.

The described supporting key of lockset, comprises key shank and the shank of the key, it is characterized in that described key shank is connected by the shank of the key bearing with the shank of the key, and the relative the shank of the key of described key shank can rotation, and one end of described the shank of the key is half arc.

Compared with prior art, the utility model sees through lockhole cannot directly touch lock core, so brute force is unblanked, technology unlocking instrument cannot arrive lock core and carry out work if do not mated key shank, realizes the protection to lock core.During use, only need use matched key to coordinate cylinder to rotate and enter lock core by gear perforate, avoided the destruction of external force to lock core, can be effectively anti-drilling, anti-technical with tinfoil and shake spoon etc. unblank, the method for unlocking such as anti-violence is turned round by force, greatly improve the safety of lockset, and have simple in structure, easy and simple to handle, the advantage such as cost of production is low.
