Abstract

The present disclosure discloses a locking device and a hopper car. A first end of a driving handle of the locking device is fixedly sleeved on a driving shaft (9); a driving fork (17) is fixedly arranged on an output end of a driving piece (16), and a second end of the driving handle (15) is rotatably arranged in a kidney-shaped hole (24) on the driving fork (17); a first guide plate (19) is arranged on the driving fork (17), and one end of a lock block (18) is arranged in a rotatable manner; a bulge (20) and a stop (21) are sequentially arranged on the lock block (18), and the end of the bulge (20) facing the first guide plate (19) is connected with the lock block (18) through a second guide plate (22); a second side surface of the first guide plate (19) can be arranged in a sliding manner with the second guide plate (22), and at least one of the second side surface of the first guide plate (19) and the second guide plate (22) is an inclined surface; the other end of the lock block (18) is provided with a third guide plate (23), and a first side surface of the first guide plate (19) and the third guide plate (23) are arranged in a sliding manner; at least one of the first side surface of the first guide plate (19) and the third guide plate (23) is an inclined surface. The present disclosure can reduce the manufacturing difficulty and manufacturing cost under the premise of ensuring the reliability of the opening/closing mechanism when the opening/closing mechanism is in a closed state.
