Description

Door lock lockhole protective cover

Technical field

The utility model belongs to the door lock accessory, is specifically related to a kind of door lock lockhole protective cover.

Background technology

The lock that existing door is installed, the lockhole on its tapered end all is to be in exposed state.This provides the opportunity of burglary crime just for some unprincipled fellows.In the burglary case, having is that the thief utilizes unlocking tool by lockhole door to be opened greatly.Also have the apprentice of something good usually to make mischief, foreign matters such as chewing gum, little batten are filled in the lockhole of exposure, make the house owner can not normal door.

The utility model content

At the shortcoming that prior art exists, the purpose of this utility model provides a kind of door lock lockhole protective cover.Door lock can prevent that the stranger from utilizing lockhole to unblank and the interior plug of past lockhole foreign matter after adopting the lockhole protective cover.

To achieve these goals, the technical solution adopted in the utility model is: door lock lockhole protective cover comprises:

One is used for fixing the turning cylinder on door leaf, and an end of turning cylinder is equipped with Back plate for lock hole, and the other end is equipped with driving lever;

One is used for fixing the driving lever deck on door leaf, and the driving lever deck is provided with projection or recess;

One is used for fixing on door leaf the shell that tapered end and Back plate for lock hole are blocked, and shell is provided with the keyhole corresponding with lockhole.

The door utility model when mounted, turning cylinder is fixedly mounted on the below of door lock, the baffle plate of one end can be sheltered from the lockhole on the tapered end of door leaf outside, the driving lever of the other end is positioned at the door leaf inner face, the driving lever deck is corresponding with driving lever to be installed on the door leaf, again with jacket on the tapered end of door leaf outside and driving lever and be fixed on the door leaf, make keyhole over against the tapered end lockhole.

During use, after in house-owner's inlet chamber, stir driving lever with hand and make baffle plate,, prevent the purpose of stranger by the lockhole crime thereby reach because driving lever can't be stirred baffle plate the exposure lockhole by projection on the driving lever deck or recess location outside door leaf over against the tapered end lockhole.House-owner when house-owner goes out, earlier in the room, driving lever rotated an angle, baffle plate opened from the lockhole rotated position, so that can use key normally to unblank by the keyhole on the shell when going home.

Further technical scheme is: a secondary tapered end is set, the secondary tapered end secondary baffle plate interior with the being located at shell formation switching mechanism that matches on shell.Can cooperate by driving lever and bayonet socket between secondary tapered end and the secondary baffle plate, perhaps cooperate by wheel and rack.

Be provided with the scheme of secondary tapered end, be mainly used in and also can drive secondary baffle plate when daytime, house-owner went out lockhole is blocked by secondary tapered end.

Major advantage of the present utility model is, can utilize the baffle plate of lockhole protective cover that lockhole is blocked, and utilizes lockhole to unblank and fill in foreign matter in lockhole to prevent the stranger, improves the safety of door lock, and simple in structure, easy to use.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

The specific embodiment

Embodiment 1

See Fig. 1 to Fig. 3, door lock lockhole protective cover comprises: be fixed on the turning cylinder 6 on the door leaf 1, an end of turning cylinder 6 is equipped with Back plate for lock hole 5, and the other end is equipped with driving lever 7; Be fixed on the driving lever deck 8 on the door leaf 1, driving lever deck 8 is provided with projection 9 (or recess); Be fixed on the door leaf 1 shell 2 that tapered end 3 and Back plate for lock hole 5 are blocked, shell 2 is provided with the keyhole corresponding with lockhole 4.

Rotating lever 7 can make baffle plate 5 open to expose lockhole, or closes and block lockhole, and the projection 9 on the driving lever deck 8 can prevent from driving lever 7 location from from the outside baffle plate 5 is opened, and the keyhole 4 on the shell 2 can insert key and normally unblank.

Present embodiment is fit to the situation of lockhole being closed in the room evening.

Embodiment 2

Another kind of structure of the present utility model is seen Fig. 4, Fig. 5, it is on the basis of embodiment 1, on shell 2, increase single raise tapered end 10, this pair tapered end 10 formation switching mechanism that matches with secondary baffle plate 12 in being located at shell 2, secondary baffle plate 12 adopt grooves 13 to cooperate with pin 14 on the shell 2 and cooperate activity to be fixed on the shell 2 with secondary apron block 15 on being fixed on shell 2.Cooperate (also can cooperate) by the bayonet socket 16 on driving lever on the lock core 11 17 and the secondary baffle plate 12 between secondary tapered end 10 and the secondary baffle plate 10 by wheel and rack.

Lock core 11 outside the room on the revolute pair tapered end 10 drives secondary baffle plate 10 transverse movements by the driving lever on the lock core 11 17, realizes the function of switch lockhole.Present embodiment is fit to from the room inside and outside situation about all lockhole can be closed, and its function is more, and result of use is better.
