[0003] The existing link beam damper is mostly fixed at both ends during use, and the relative position accuracy of the link beam and the damper is extremely high during installation, if there is a slight deviation during installation, the damper will be subjected to additional unreasonable force during work, which may cause hidden dangers to the normal use of the damper, and reduce the service life and reliability of the damper, therefore, a new two-end rotation friction type link beam damper is provided.

[0008] Preferably, the right part of the outer surface of the adjusting seat is fixedly connected with the fixed block, the left end of the connecting block is fixedly connected with the mounting plate, and the width of the connecting block is less than the width of the four grooves.

[0009] By adopting the above technical scheme, the connecting block can be placed inside the four grooves, and the adjusting angle is enlarged.

[0010] Preferably, the right half of the damping ball is located inside the damping cavity, and the outer surface of the damping ball is movably connected with the inner wall of the damping cavity groove.
