The invention provides a telescopic locking device for a railway container flatcar, which comprises a connecting seat, a sliding mortise lock piece, a sliding positioning piece and a sliding pushing piece, and the connecting seat penetrates through the flatcar along the vertical direction; the sliding mortise lock part axially penetrates through the connecting seat and is in sliding fit with the connecting seat, the sliding mortise lock part can be in insertion fit with the insertion groove, a first moving cavity is formed in the lower portion of the sliding mortise lock part, a second moving cavity is formed in the sliding mortise lock part, and the sliding mortise lock part is locked through a first movement stopping part; the sliding positioning piece is slidably connected into the second moving cavity and is used for being matched with the limiting groove in an inserted mode, and a guide inclined face is arranged at the inner end of the sliding positioning piece; and the sliding pushing piece is connected into the first moving cavity in a sliding mode, the sliding pushing piece can push the sliding positioning piece to be inserted into the limiting groove, and the sliding pushing piece is locked through the second movement stopping piece. According to the telescopic locking device for the railway container flatcar, the container can be locked on the flatcar, the container is prevented from inclining laterally, and potential safety hazards are eliminated.

    本发明提供了一种铁路集装箱平车用伸缩式锁闭装置,包括连接座、滑移插锁件、滑移定位件以及滑移顶推件,连接座沿上下方向贯穿平车设置;滑移插锁件轴向贯穿连接座设置、且与连接座滑动配合,滑移插锁件能够与插接槽插接配合,滑移插锁件的下部设有第一移动腔,滑移插锁件上设有第二移动腔,滑移插锁件通过第一止移件锁定;滑移定位件滑动连接于第二移动腔内、且用于与限位槽插接配合,滑移定位件的内端设有导向斜面;滑移顶推件滑动连接于第一移动腔内,滑移顶推件能够顶推滑移定位件插接于限位槽内,滑移顶推件通过第二止移件锁定。本发明提供的铁路集装箱平车用伸缩式锁闭装置,能够将集装箱锁定于平车上,避免集装箱侧倾,消除安全隐患。
