Abstract
The utility model discloses an automobile theft-guarded anti-disassembly device, which is characterized in that the device comprises an anti-disassembly fastener and an ant-sawing cover. The anti-sawing cover is covered on the installment screw of the automobile theft-guarded lock. The anti-disassembly fastener fixes the anti-sawing cover on the automobile theft-guarded lock. The anti-disassembly fastener has a good anti-disassembling function, which cannot be disassembled without a special tool. The anti-sawing cover is made from anti-sawing steel with different shapes matched to the installment screws of the automobile theft-guarded locks at the different locations. The anti-sawing cover conceals the installment screws, prohibiting the installment screws from illegal disassembly and greatly increasing the theft-guarded ability of the automobile theft-guarded locks.
Description
Technical field
The utility model relates to the anti-disassembly mechanism of a kind of automobile anti-theft lock.
Background technology
Automobile burglar is the topic that people are concerned about always, existing automobile anti-theft lock generally all will be fixed on the automobile by fasteners such as mounting screws, but because outside these mounting screws are exposed to, be easy to just can illegally be dismantled by the people, thereby automobile anti-theft lock is also disassembled, automobile anti-theft lock has also just lost theft-proof function like this, makes the car owner suffer economic loss.
Summary of the invention
The utility model is at above deficiency, provide a kind of simple in structure, can prevent the anti-disassembly mechanism that the automobile anti-theft lock mounting screw is disassembled.
In order to achieve the above object, the utility model adopts following technical scheme:
Automobile anti-theft lock described in the utility model is prevented disassembly mechanism, comprises tamper fastener and anti-saw lid, and described anti-saw lid covers on the mounting screw of automobile anti-theft lock, and described tamper fastener is fixed on automobile anti-theft lock to anti-saw lid; Described tamper fastener can be the disconnected screw of lock, and the disconnected screw head of lock is divided into upper and lower two parts, and a concave ring groove is arranged between the upper and lower part, the disconnected screw head top of lock can be the socket head cap screw head, also can be the outer-hexagonal screw head, the disconnected screw head bottom of lock is circular, also can be conical; Described tamper fastener also can be that screw bolt and nut is formed, and it is hexagon that an end of nut does not have internal thread profile, and its other end band internal thread profile is circular, and the connection place is a concave ring groove in the middle of the two ends.
Described anti-saw lid is provided with one or above T shape screw perforation, and it can bury disconnected screw head lower part of above-mentioned lock or above-mentioned bolt cap.
The utility model adopts above technical scheme that such beneficial effect is arranged, and described tamper fastener has good tamper effect, and instrument that need not be special can not be dismantled it.Described anti-saw lid is made with anti-sawn timber material, it can make different shapes to cooperate the automobile anti-theft lock mounting screw of different use locations, anti-saw lid covers mounting screw and stashes, can prevent that the automobile anti-theft lock mounting screw from illegally being dismantled, strengthen the anti-theft capability of automobile anti-theft lock greatly.

The specific embodiment
The utility model will be further described below in conjunction with specific embodiment, but be not limited to following example.
Embodiment one
Shown in Fig. 1,4,5 and 6, the utility model comprises disconnected screw 1 of lock and anti-saw lid 7, and the disconnected screw 1 of lock is divided into upper and lower two parts (2,3), and the socket head cap screw head is made on top 2, and lower part 3 is circular, makes a groove shape 4 between top 2 and the lower part 3; Anti-saw lid 7 is provided with a T shape screw perforation 8, it can bury the disconnected screw head lower part 3 of above-mentioned lock, when using, on the mounting screw substrate 10 of automobile anti-theft lock, open a screw hole, the disconnected screw of above-mentioned lock is fixed up anti-saw lid 7 by this screw hole, anti-saw lid 7 covers the automobile anti-theft lock mounting screw, after tightening, the disconnected screw 1 of lock continues it is applied the moment of overload, the disconnected screw 1 of lock disconnects at concave ring groove 4, the disconnected screw head lower part 3 of only remaining lock, because lower part 3 does not have can be for the structure of dismounting, therefore it has good anti-disassembling function, anti-saw lid 7 covers mounting screw, and it is hidden, and can antitheftly play a part protection again.
Embodiment two
The outer-hexagonal screw head is made on the top 2 of disconnected screw 1 head of above-mentioned lock, and other is as described in the enforcement mode one.
Embodiment three
As Fig. 2,3,4, shown in 7 and 8, bolt 5 and nut 6 combinations are fixed to anti-saw lid 7 on the automobile anti-theft lock mounting screw substrate 11, one end, the 62 no internal thread profile of described nut 6 are hexagon, its other end 61 band internal thread profile are circular, the connection place is a concave ring groove 63 in the middle of the two ends, nut 6 tightens the back to be continued it is applied overload torque, nut 6 is disconnected broken at concave ring groove 63 places, taking out no internal thread profile is a hexagonal end 62, a remaining end 61 is hidden in the counterbore of substrate, because a remaining end 61 does not have the detouchable structure, so this device of instrument that need not be special can not be disassembled.
Embodiment four
Shown in Fig. 1 and 9, anti-saw lid 9 can be arranged to bell-type, and other is as described in the embodiment one.
As known from the above, the anti-saw lid 7 in the utility model can be made different shapes, with the anti-dismounting of the automobile anti-theft lock mounting screw needs that cooperate different use locations; The lower part of the disconnected screw head of described lock can also coning be waited by seat.
