The invention relates to the technical field of lightning rods, and discloses a steel tube lightning rod for relieving wind vibration. The steel tube lightning rod comprises a body, a hollow cavity ina circular truncated cone shape is formed in the body, a support disc is arranged in the hollow cavity, and coaxially arranged fan ring grooves are formed in the support disc. The fan ring grooves are internally provided with a plurality of balls which can roll along the fan ring grooves, the balls are connected with ropes, and the bottom ends of the ropes penetrate through the fan ring grooves to be connected with swinging members. The steel tube lightning rod has a reasonable and compact structure and is convenient to use, the balls which can jump or move on the support disc are arranged, the swinging members are connected to the balls, when the lightning rod is subjected to wind vibration, a large amount of damping is generated by the jumping or moving of the single ball, the collisionbetween the multiple balls, the swing of the single swinging member and the collision of the multiple swinging members, the vibration of the entire steel tube lightning rod is reduced, the damage tothe steel tube lightning rod due to the wind vibration is reduced, and the service life is prolonged.
