The invention discloses a sliding rail locking and unlocking device of a car seat. A locking and unlocking device body is arranged between an upper sliding rail and a lower siding rail, three independent lock pins are arranged in the locking and unlocking device body, the three lock pins are stirred by a guide plate and a claw plate arranged on the locking and unlocking device body to do vertical pin inserting motion, and a plurality of equidistantly-distributed kidney-shaped lock holes are formed in the groove bottom of the lower sliding rail. According to the technical scheme that when the sliding rails are locked every time, two of the three lock pins are always inserted into the lock holes in the groove bottom of the lower sliding rail for symmetric locking, the problems that in the prior art, the structure is complex, the short-distance adjusting function cannot be achieved, and unlocking out of control is prone to happening are solved. According to the structural characteristics that two lock pins participate in locking, the locking position of the upper sliding rail is prone to being adjusted in short distance through the equidistantly-distributed lock holes in the lower sliding rail, the sliding rail locking and unlocking device of the car seat achieves the aims of being simple in structure, reliable in locking and resistant to out-of-control unlocking, and achieving the short-distance adjusting function.
