Automatic timing coded lock

An automatic timing coded lock relates to a lockset. The automatic timing coded lock comprises a spring bolt (1), a locking spring (2), an axle (3), a deflector rod (4), a timing device (5), a tapered end (6), a code inputting device (7) and a lock rod (8). The spring bolt (1) is connected with the locking spring (2) and is placed on one side of the tapered end (6) interior; the axle (3) is connected with the deflector rod (4) and is arranged on a lateral lower part of the spring bolt (1); the timing device (5) is connected with the deflector rod (4); the code inputting device (7) is arranged on the outer of the other side of the tapered end (6); one end of the lock rod (8) is rotationally and fixedly connected with the tapered end (6); and the other end of the lock rod (8) is snapped with the spring bolt (1). A code is needed to be set when the automatic timing coded lock is to be locked, so that a vehicle lock can only be opened with the code within the timing time.
