[0020] Working Principle: When using this utility model, the damper is first transported to the installation position, and all components are checked for loosening or damage during transportation. Based on the design requirements and actual dimensions of the frame shear wall, the installation position of the damper is determined. The lower support 1 is placed in the predetermined lower installation position. By rotating the threaded sleeve 14, its position on the threaded post 12 is adjusted so that the lower support 1 reaches a suitable height. Then, the locking nut 13 is tightened to fix the lower support 1. Next, the upper support 2 is connected using a connecting mechanism. The first connecting block 6 and the second connecting block 8 are connected by passing the smooth bolt 3 through the first connecting hole 7 and the second connecting hole 9. The smooth bolt 3 is tightened to ensure a tight connection between the connecting blocks, completing the assembly of the connecting mechanism and further enhancing the connection strength between the upper and lower supports. When the frame shear wall is subjected to external force, the force is transmitted to the damper through the upper and lower supports. The spring 5 in the connecting mechanism first undergoes elastic deformation, absorbing some energy and mitigating the impact of the external force on the structure. Simultaneously, the damping telescopic rod 4... It can further consume energy and buffer external forces, thereby reducing the vibration amplitude of the structure. During the vibration process, the threaded sleeve 14 of the support mechanism remains stable under the action of the anti-slip pad 15 and will not be displaced due to vibration, ensuring that the damper is always in the correct working position and ensuring the stability of the entire structure.
