The invention relates to the field of inspection doors of bullet trains, in particular to an inspection door device and a bullet train, which are used for solving the problem that the inspection door is automatically opened in the running process of the bullet train. The inspection door device comprises a door frame and a door plate slidably arranged on the door frame, slideways are arranged on the two sides of the door frame, a sliding assembly is arranged on the door plate, and the sliding assembly can slide along the slideways to drive the door plate to move between an opening position and a closing position. A first locking structure is arranged on the door frame, and a second locking structure is arranged on the door plate. When the sliding assembly is located at the closing position along the sliding way, the first locking structure and the second locking structure are matched to lock the door plate at the closing position, and the inspection door is prevented from being automatically opened when closed. The limiting supporting structure is located between the sliding way and the first locking structure, when the first locking structure is matched with the second locking structure, the limiting supporting structure abuts against the inner side face of the door plate, the door plate can be effectively prevented from being concaved inwards, and a gap is prevented from being generated between the door plate and the door frame.

    本发明涉及动车的检查门领域,尤其涉及一种检查门装置及动车,用于解决动车行驶中检查门自行打开的问题。检查门装置包括门框和可滑动地设置在门框上的门板,门框两侧设置有滑道,门板上设置滑动组件,滑动组件能够沿滑道滑动,以带动门板在打开位置和关闭位置之间运动;门框上设置有第一锁紧结构,门板上设置有第二锁紧结构。当滑动组件沿滑道在关闭位置时,第一锁紧结构与第二锁紧结构配合将门板锁紧在关闭位置,防止检查门在关闭时自行打开。限位支撑结构位于滑道和第一锁紧结构之间,在第一锁紧结构和第二锁紧结构配合时,限位支撑结构抵靠在门板内侧面,可以有效防止门板内凹,并且防止门板与门框之间产生缝隙。
