[0021] In this embodiment: the lower end of the mounting section 3 is inserted into the through hole 4, and the through hole 4 plays a guiding role for the mounting section 3; the spring rod 8 between the lower support sleeve 6 and the upper support sleeve 7 on the outer wall can provide a stable supporting force for the mounting section 3, maintain the stability of the base section 2 and the mounting section 3, and when the base section 2 is subjected to external impact or vibration, the spring rod 8 can absorb and disperse the energy, thereby playing a buffering role; the shock absorber 5 is located between the bottom of the through hole 4 and the mounting section 3. When the base section 2 is vibrated, the shock absorber 5 can reduce and eliminate the vibration force transmitted from the base section 2 to the mounting section 3 and the vibration force transmitted from the mounting section 3 to the base section 2. The vibration of the foundation section 2 is reduced, and the vibration transmission path between the foundation section 2 and the installation section 3 is isolated through the characteristics of the shock-absorbing spring 11 and the rubber lining 12, thereby reducing the transmission of vibration from the foundation section 2 to the installation section 3, and the shock absorber 5 can absorb and disperse vibration energy, and resist external force and torque, to protect the installation section 3 and prevent the installation section 3 from being damaged by vibration; at the same time, the guide rod between the lower support sleeve 6 and the upper support sleeve 7 guides and limits the foundation section 2 and the installation section 3, and strengthens the stability of the connection between the foundation section 2 and the installation section 3, thereby improving the stability of the installation structure of the steel structure.

[0022] As a technical optimization solution of the present invention, grooves 21 are opened on both sides of the lower side of the installation section 3 towards the two ends of the first screw 19, and nuts 22 threadedly connected to the two ends of the first screw 19 and the two ends of the second screw 20 are respectively provided in the two grooves 21 and on both sides of the base section 2.

[0028] Working principle: First, the upper connecting seat 13 is sleeved in the upper positioning groove 15 and fixed with the first screw 19. When the lower end of the mounting section 3 is inserted into the through hole 4, the lower connecting seat 14 at the bottom of the shock absorber 5 is aligned with the lower positioning groove 16, and the lower connecting seat 14 is sleeved in the positioning groove. The lower connecting seat 14 is fixed to the lower positioning groove 16 by the second screw 20; and multiple spring rods 8 are vertically installed between the lower support sleeve 6 and the upper support sleeve 7; when the base section 2 is vibrated, the spring rods 8 and the shock absorber 5 can reduce and eliminate the vibration force transmitted from the foundation section 2 to the installation section 3 and the vibration transmitted from the installation section 3 to the foundation section 2. The characteristics of the shock-absorbing spring 11 and the rubber lining 12 can isolate the vibration transmission path between the foundation section 2 and the installation section 3, thereby reducing the transmission of vibration from the foundation section 2 to the installation section 3. The shock absorber 5 can absorb and disperse vibration energy and resist external forces and torques to protect the installation section 3 from vibration damage, thereby improving the structural stability of the steel structure.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
