The invention discloses a locking system for a door, a reinforced protective door comprising the locking system and a ship, the locking system comprises a first-stage locking device, the first-stage locking device comprises two mounting seats, the mounting seats are arranged on a door frame or a vertical wall adjacent to the door frame, and the first-stage locking device comprises a first-stage locking device and a second-stage locking device, the two mounting seats are symmetrically arranged on the door frame or the vertical wall on the left side and the right side of the door; and at least one end of the blocking piece is detachably connected with the corresponding mounting seats, and when the door is in a closed locking state, the two ends of the blocking piece are located in the two mounting seats correspondingly, so that the blocking piece is located on the back of the door, and the door is prevented from moving in the opening direction. According to the door locking system, when the door is in the closed locking state, the blocking piece and the mounting base are matched to form two blocking positions on the left side and the right side of the door in a symmetrical mode, the resultant force formed by the two blocking positions blocks external force of the door in the opening direction, and by means of the strength of the blocking piece and the mounting base, the strength of the door locking system is remarkably improved.

    本发明公开了一种用于门的锁止系统、含其的加强型防护门及船舶,所述锁止系统包括一级锁止装置,所述一级锁止装置包括有:两个安装座,所述安装座设置在门框或与所述门框邻接的立壁上,两个所述安装座在门左右两边的所述门框或所述立壁上对称设置;阻挡件,所述阻挡件的至少一端与对应的所述安装座可拆卸连接,在门处于关闭锁止状态时,所述阻挡件的两端分别位于两个所述安装座内,使得所述阻挡件位于门的背部,以阻止门在打开方向的运动。在本发明中,在门处于关闭锁止状态时,阻挡件与安装座的配合在门的左右对称形成两个阻挡位,两个阻挡位形成的合力阻挡门在打开方向的外力,借助阻挡件与安装座的强度,门的锁止系统的强度显著提升。
