Three, summary of the invention

The purpose of this utility model provide a kind of safety good, be difficult for stolen anti-theft device for vehicle.

The purpose of this utility model is achieved like this: a kind of anti-theft device for vehicle, comprise jaw that is arranged on the handlebar and the sleeve pipe that is arranged on the vehicle body, described jaw inserts in the sleeve pipe, it is characterized in that: on the corresponding wall of jaw and sleeve pipe, be provided with the through hole that runs through mutually, be provided with pin in the through hole and make pin extend into lock in the through hole.For guaranteeing that lock can be connected on the vehicle securely, described lock can be welded on the sleeve pipe.

For preventing that lock from being pried open, described lock comprises lock housing and lock core, and an end inwall of tubulose lock housing is provided with screw thread, and the other end is fixed with lock core; Pin is fixed on screwed base one end, and this base other end is provided with the notch that matches with the inserted sheet of lock core, and base is installed on the lock-shell lining screw thread.For keeping lock core to be fixedly mounted in for a long time in the lock housing, can adopt the criss-cross lock core.

The utility model will be locked and be welded on jaw and sleeve pipe junction securely, and jaw and sleeve pipe are fixed together by pin during pinning, and handlebar can not be rotated, thereby car can't travel at this moment, if by force lock is damaged, then destroyed the structure of whole vehicle, car also can't have been ridden again.Compared with prior art, adopt anti-theft device for vehicle described in the utility model after, realized ruining lock and must ruin car earlier, its advantage is: safety is good, even also can't further dispose of stolen goods after car is stolen.
