Sealing device for rail transit vehicle connector

The utility model belongs to the technical field of coupler connectors of rail transit vehicles, and particularly relates to a sealing device for a connector of a rail transit vehicle. The whole sealing piece is cylindrical and hollow, and one end face of the sealing piece is a sealing contact face. The sealing piece comprises at least one deformation part; the deformation part is an annular groove with an opening inward or outward in the radial direction of the sealing piece or an internal groove formed in the sealing piece; the deformation part is arranged close to the sealing contact surface; the sealing contact face is an annular plane and is perpendicular to the axis of the sealing piece. According to the utility model, a mode of combining compression deformation and distortion deformation is adopted, so that a large axial and radial working range can be met, and the stability and reliability of the connector after insertion are ensured. 本实用新型属于轨道交通车辆车钩连接器技术领域，具体涉及一种用于轨道交通车辆连接器的密封装置，包括密封件；密封件整体呈柱形，内部中空，一
