The invention provides an anti-loosening tangential pin and an oil pipe assembly, and belongs to the technical field of controllable-pitch propellers. The anti-loosening tangential pin comprises a pin rod, an elastic piece and a locking cylinder, limiting protrusions are arranged on the outer circumferential wall of one end of the pin rod, the locking cylinder is provided with an open end and a closed end which are opposite, the inner circumferential wall, close to the open end, of the locking cylinder is provided with an inner flange, the inner flange is provided with mounting grooves in one-to-one correspondence with the limiting protrusions, and the elastic piece is arranged in the mounting grooves. The installation groove extends from one end of the inner flange to the other end of the inner flange, the inner diameter of the inner flange is the same as the outer diameter of the end, provided with the limiting protrusion, of the pin rod, and the distance between the inner flange and the closed end is larger than or equal to the length of the limiting protrusion in the axial direction of the locking cylinder. The elastic piece is located in the locking cylinder, and the two ends of the elastic piece abut against the end, provided with the limiting protrusion, of the pin rod and the closed end respectively. The problem that the pin hole is prone to damage when the oil pipe assembly is repaired can be solved.
