Double anti-theft lock for vehicle

The utility model relates to a doubly-linked anti-theft lock for a vehicle. The utility model is composed of two independent half locks which are respectively provided with a lock body (1) and a lock body (7), wherein one side of the lock body (1) is provided with an inserting rod (4), and the other side is provided with an inserting rod slot; one side of the lock body (7) is provided with an inserting rod (3), and the other side is provided with an inserting rod slot; the lock bodies (1) and (7) are respectively provided with a lock core (2) and a lock core (5). The two half locks can adopt the different lock cores (2) and (5) to enhance the anti-theft performance; when locking, the inserting rod (4) of the lock body (1) is inserted into the inserting rod slot on the lock body (7), simultaneously, the inserting rod (3) of the lock body (7) is also inserted into the inserting rod slot on the lock body (1), the inserting rods (4) and (3) are respectively clamped by a lock tongue (6) of the opposite party to be mutually locked. Due to the adoption of the scheme of mutual paired lock and simultaneous unlocking, the doubly-linked anti-theft lock causes a robber to respectively take a lock picking tool in both hands to simultaneously pick the lock from both sides, because a man can not whistle and drink at he same time, the difficulty is obvious and the lock is almost impossible to pry open. Thereby, the anti-theft performance of the utility model is superior.
