The invention provides a third-rail lower pneumatic current collector. Technical problems of the traditional three-rail lower pneumatic current collector for a rail transit vehicle that a plurality of cylinders are used, a plurality of gas circuits are arranged, the operation is complicated, the cost is high and the like are mainly solved. The third-rail lower pneumatic current collector is characterized by comprising a mounting back plate assembly(1), a cylinder crank connecting rod assembly(2), a tension spring assembly (3), a left flexible bearing seat (4), a right flexible bearing seat (7), an insulated swinging arm (5), a current collecting slip shoe (6), an upper insulated protective cover (8), a lower insulated protective cover (9) and the like, wherein the left flexible bearing seat (4) and the right flexible bearing seat (7) are connected with the swinging arm; and the current collecting slip shoe (6) is mounted on the swinging arm (5). As only one cylinder is needed to be connected with a shoe derailing crank assembly, the third-rail lower pneumatic current collector provided by the invention, is simply and reliably structured and convenient to operate and maintain. The third-rail lower pneumatic current collector provided by the invention can be widely applied tovarious three-rail current collectors for the rail transit vehiclesor used for improving the original current collectors.
