The utility model includes a protective board that can be fastened on handle on the inner side of the automobile door lock. A slender baffle plate is provided on the lower left side of the protective board to defend the connecting rod of the lock and the shifting fork thereof. The upper left side of the baffle plate bends backward by 90 degrees to form the left anti-prying plate. The lower end of the left anti-prying plate is connected to a U-shaped bent plate to prevent poking of the shifting fork. The lower left side of the baffle plate bends forward by 90 degrees to form a protective board to prevent poking of the shifting fork from the top down on the left. The right part of the baffle plate bends backward by 90 degrees to form the right anti-prying plate. The utility model can fully protect the shifting fork on the lock of automobile and the connecting rod thereof.

Description

The automobile door lock anti-picking device

(1) technical field

The utility model relates to a kind of vehicular spare parts, particularly a kind of automobile door lock anti-picking device.

(2) background technology

The stolen phenomenon of automobile is very general in the actual life, shows as social security problem on the one hand, then shows as the automobile burglar measure imperfection of prior art on the other hand.Automobiles such as for example at present commercially available " prosperous river ", " Xiali ", its automobile door lock system comprises lock core and the collision type lock body that an available key is unblanked or locked outside car, have 4 link rods on the lock body, outside Che Nei or car, utilize handle to open the door when wherein two link rods are respectively applied for released state; Its lower end of two other link rod respectively with lock body on be used to shift fork (its left side of unblanking or locking, right arm) links to each other, its upper end then links to each other with the lock core (can close with key outside and buckle/thread off) or the handle of buckleing/threading off that can be used for closing that is located on interior door and window one side position of car respectively, when key left-right rotation or handle are depressed, green phase answers link rod to drive left and right sides shift fork action can to make lock body close button or thread off (when closing the button state when putting on, the car door of no matter outside Che Nei still is car, all not opening, then opposite during trip status) its structure of this automobile door lock system is more cleverly, thereby obtained widespread usage, its shortcoming is that the thing that cartheft passes through thin band iron (as the long saw bar) and so on is down disclosed along sealing band on glass, as long as disclose a shift fork (left side, right arm) or the link rod that is attached thereto, just can be easily as with key or handle, lock body is threaded off and release, can be thereby do not need to destroy car door (breaking glass) with car door opening, and car is stolen safely, or article in the car are stolen.

(3) summary of the invention

Task of the present utility model provides a kind of automobile door lock anti-picking device, and it should be able to carry out comprehensive protection to shift fork and the link rod thereof that being used on the car door lock closed button/dropout, thereby prevents that cartheft under the situation of not destroying car door, committing theft car door opening.

Technical solutions of the utility model are as follows:

A kind of automobile door lock anti-picking device, it is characterized in that having a backplate on the be fixed on automobile door lock that is square the substantially internal handle, below the left side of backplate, be connected with elongated being used for and cover the baffle plate of door lock link rod and its shift fork right arm, the left upper portion of baffle plate is 90 ° of warpages and constitute the anti-skid plate in a left side backward, the lower end of the anti-skid plate in left side is connected with the anti-bent plate of disclosing of shift fork that a section is " U " font, 90 ° of bendings and constitute one and can prevent from its left side or stir the guar plate of shift fork from its left side from top to down that the right side of baffle plate 90 ° of warpages backward constitutes the anti-skid plate in a right side forward in the bottom, left side of baffle plate.

Further improvement of the utility model is in described lower end at described baffle plate that backward 90 ° of warpages have one to be used for preventing that cartheft from stirring the pick-proof base plate of shift fork from its bottom with hook.

Owing to adopted technique scheme, the utility model can carry out comprehensive, multi-angle protection to the automobile door lock shifting fork mechanism of original exposure by upper and lower, left and right, preceding (back is by car door protection itself) several orientation, thereby make the instrument of prizing and stealing of band iron and so on can't touch shift fork and link rod thereof, and then can prevent to steal the generation of car incident effectively.
