The utility model relates to the technical field of elevator guide rails, and discloses an oil injection type T-shaped guide rail for an elevator, according to the scheme, the oil injection type T-shaped guide rail comprises a T-shaped guide rail body, a mounting plate is fixedly connected to the top end of the T-shaped guide rail body, and an oil tank is fixedly connected to the top side of the mounting plate. When the friction force on the surface of the T-shaped guide rail body is not increased, the motor is in an idling state, once the friction force is increased, a friction plate can extrude an extrusion switch along with up-down movement of an elevator car, after the extrusion switch is extruded, an electrified spring is electrified and contracts, and a clamping block is clamped into a clamping groove; meanwhile, due to the arrangement of the two electrified springs, when the friction force of one side of the T-shaped guide rail body is increased and the friction force of the other side of the T-shaped
