The invention discloses a double-opening sliding plug door system which comprises a bearing driving mechanism, a door leaf, a lower swing guiding device, a vertical synchronous rod assembly and a middle restraining lock hook, and the door leaf, the lower swing guiding device, the vertical synchronous rod assembly and the middle restraining lock hook are arranged in a bilateral symmetry mode relative to the center of the door system. An end restraint device on the bearing driving mechanism is used for restraining the two ends of the cross beam, and a cross beam multi-point restraint device of the cross beam assembly is constructed by combining a middle nut assembly over-dead-point locking device; a rotating arm on the vertical synchronous rod assembly reliably restrains the upper part of the door leaf rear stop; the vertical synchronous rod assembly drives the lower swing guide device to lock the lower portion of the door leaf rear stop in the X direction and the Y direction, the lower portion of the door leaf can be inserted in the direction of about 35 degrees, and the stop pin can restrain the lower portion of the door leaf front stop. A reliable multi-point restraint system of the door system is constructed by combining the mutual coupling effect of the restraint lock hook and the lock catch in the middle of the rear stop, and the bearing strength of the door system is high; the door system has good static and dynamic sealing performance.
