The invention relates to the technical field of railway wagon braking, in particular to a high-reliability pressing type quick coupler for a railway wagon, which comprises a coupler body for connecting two brake pipes, locking nuts are arranged at two ends of the coupler body, each locking nut comprises a screwing part and a pressing part which are coaxially arranged, the screwing part is in threaded connection with the coupler body, and the pressing part is in threaded connection with the coupler body. An elastic gasket is arranged between the inner wall of the pressing part and the brake pipe, the elastic gasket is provided with an opening, the two ends of the opening of the elastic gasket are arranged in a staggered mode, the inner wall of the pressing part is provided with a pressing conical surface, and the pressing conical surface is used for simultaneously extruding the elastic gasket in the axial direction and the circumferential direction. The opening of the elastic washer is contracted to fix the brake pipe, and the elastic washer is axially deformed to rebound to extrude the locking nut. According to the invention, the normal position capability, the anti-loosening capability and the sealing capability of the joint are improved, and the safety of vehicle application is improved.
