The invention relates to 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; a driving fork is fixedly arranged at an outputend of a driving piece; the second end of the driving handle is rotatably arranged in a waist-shaped hole in the driving fork; a first guide plate is arranged on the driving fork; one end of the locking block is rotatably arranged, a protrusion and a spigot are sequentially arranged on the locking block, the end, facing the first guide plate, of the protrusion is connected with the locking blockthrough a second guide plate, the second side face of the first guide plate and the second guide plate can be arranged in a sliding mode, and at least one of the second side face of the first guide plate and the second guide plate is an inclined face; a third guide plate is arranged at the other end of the locking block, the first side face of the first guide plate and the third guide plate are arranged in a sliding mode, and at least one of the first side face of the first guide plate and the third guide plate is a slope. On the premise that the reliability of an opening and closing mechanismin the closed state is guaranteed, the production and manufacturing difficulty and the manufacturing cost can be reduced.

    本发明涉及一种锁闭装置以及漏斗车。锁闭装置的驱动柄的第一端固定套装在主动轴上;驱动叉固定设置在驱动件的输出端上,驱动柄的第二端可转动地设置在驱动叉上的腰形孔中,驱动叉上设置有第一导向板,锁块的一端可转动设置,锁块上依次设置有凸起和止口,凸起朝向第一导向板的一端和锁块之间通过第二导向板连接,第一导向板的第二侧面可和第二导向板滑动设置,第一导向板的第二侧面和第二导向板中至少一个为斜面;锁块的另一端设置有第三导向板,第一导向板的第一侧面和第三导向板滑动设置,第一导向板的第一侧面和第三导向板中至少一个为斜面。本发明在保证开闭机构关闭状态下的可靠性的前提下,可降低生产制造难度以及制造成本。
