The invention relates to a locking and unlocking mechanism. The locking and unlocking mechanism comprises horizontally-arranged rotary supports, swig arms rotationally supported in the rotary supports, a pull plate fixedly connected with the swing arms, an unlocking pull rod with one end horizontally rotationally connected to the pull plate, unlocking connecting plates with one ends horizontally rotationally connected to the swing arms and locking supports horizontally rotationally connected to the other ends of the unlocking connecting plates. An included angle is formed between the pull plate and the length directions of the swing arms. The invention further relates to a sliding plug door system. The sliding plug door system comprises the locking and unlocking mechanism, a large bottom plate, two longitudinal sliding assemblies, a bearing optical shaft and a supporting cross beam horizontally connected between the two longitudinal sliding assemblies and two tackles slidingly connected to the bearing optical shaft. The rotary supports are fixed to the supporting cross beams, the locking supports are fixed to the large bottom plate, when a door leaf is in a closed state, the axes of the unlocking connecting plates and the axes of the swing arms are collinear, and the axes of the unlocking connecting plates and the axes of the swing arms are vertical to the length direction of the large bottom plate. When the door leaf is closed, locking is carried out, and the door leaf is more reliably closed.

    本发明涉及一种锁闭解锁机构,其包括水平设置的转动支座、转动支撑于转动支座中的摆臂、与摆臂长度方向存在夹角且与摆臂固接的拉板、一端水平转动连接于拉板上的解锁拉杆、一端水平转动连接于摆臂上的解锁连接板,以及水平转动连接于解锁连接板另一端的锁闭支座。本发明还涉及一种塞拉门系统,其包括锁闭解锁机构、大底板、两个纵向滑动组件、水平连接于两个纵向滑动组件之间的承载光轴和支撑横梁,以及滑动连接于承载光轴上的两个滑车;转动支座固定于支撑横梁上,锁闭支座固定于大底板上,当门扇处于关闭状态时,解锁连接板的轴线与摆臂的轴线共线且与大底板长度方向垂直。本发明可以在门扇关闭时进行锁闭,使门扇的关闭更为可靠。
