The sliding plug door restraining assembly comprises a stop pin support, a cam and a fixing piece, one end of the stop pin support is hinged to the end of a bearing beam for supporting a door leaf to slide, the other end of the stop pin support is connected with the fixing piece, the cam is connected with the end of a lead screw for driving the door leaf to move, the cam rotates along with the lead screw, and the door leaf is closed. The stop pin support is driven by the bearing beam to be close to the lead screw, the cam pushes the stop pin support from the lower side of the stop pin support, and the upper side of the stop pin support abuts against the fixing piece. In the invention, the lead screw and the mounting frame are simultaneously introduced as constraint components of the bearing beam, so that the stable constraint of the bearing beam is realized.
