The invention discloses a rubber threading sleeve. The rubber threading sleeve comprises a vibration screen threading sleeve body made of a rubber material. The threading sleeve body is composed of two parts. A conical vibration reduction sleeve body with the gradually-tapered outer wall is connected to an outer port of a conical threading sleeve body. A clamping groove is formed between the conical threading sleeve body and the conical vibration reduction sleeve body and used for fixing the threading sleeve body to a screening machine bottom barrel. A circle of baffle is fixed to the outer wall of the vibration reduction sleeve body on the outer side of the clamping groove. The rubber threading sleeve with the buffer performance is used for replacing a hollow core screw nut structure made of a rigid material, so that vibration strength of a wire at an inlet/outlet part is greatly reduced, and the service life of the wire can be greatly prolonged.
