[0002] A viscous damper is a common energy dissipation device. Currently, the internal structure of the fluid damper commonly used in the field of civil engineering basically belongs to the jet type. Its working principle is that through the reciprocating movement of the piston, the viscous liquid in the cylinder is squeezed to flow through the small holes on the piston head, thereby providing damping force for the engineering structure. Application No. CN202310759633.X discloses a displacement adaptive staged circular viscous damper, including an outer cylinder. One end of the outer cylinder is fixedly connected with a first connecting earring, and the other end of the outer cylinder is provided with a second connecting earring... The piston rod in this patent is exposed. Due to the relatively dusty use environment, the exposed piston rod will accumulate dust, resulting in damage to components such as the damper and the sealing ring when the piston rod expands and contracts, affecting the service life of the damper. Therefore, we introduce an adaptive viscous damper. Content of the Utility Model

[0026] An adaptive viscous damper, including a damper body 1, a first connecting block 2 is fixedly connected to the rear end of the damper body 1, a piston rod 3 is installed and connected to the front end of the damper body 1, a round block 5 is fixedly connected to the front end of the piston rod 3, a second connecting block 4 is fixedly connected to the front end of the round block 5, the front end of the second connecting block 4 and the rear end of the first connecting block 2 are both arc-shaped structures, the diameter of the round block 5 is the same as the diameter of the damper body 1, the second connecting block 4 is movably connected to a second mounting mechanism 8 through a rotating shaft, the first connecting block 2 is movably connected to a first mounting mechanism 6 through a rotating shaft, the first mounting mechanism 6 and the second mounting mechanism 8 have the same structure, and the outer surface of the damper body 1 and the outer surface of the round block 5 are jointly movably connected to a dust-proof mechanism 7.
[0027] In this embodiment, the dust-proof mechanism 7 includes a rubber sleeve 71. A second hoop 74 is sleeved on the front part of the outer surface of the rubber sleeve 71, and a first hoop 72 is sleeved on the rear part of the outer surface of the rubber sleeve 71. The second hoop 74 and the first hoop 72 have the same structure, and bolts 73 are installed and connected on both the first hoop 72 and the second hoop 74; the rubber sleeve 71 is located on the outer surfaces of the damper body 1 and the round block 5; the second hoop 74 is sleeved on the outer surface of the round block 5, and the first hoop 72 is sleeved on the outer surface of the damper body 1.
[0028] Through the above scheme: The rubber sleeve 71 is sleeved and tightened on the outer surfaces of the damper body 1 and the round block 5 by the action of the second hoop 74 and the first hoop 72, so that the rubber sleeve 71 shields the piston rod 3, thereby preventing dust from contacting the outer surface of the piston rod 3.
[0029] In this embodiment, the second mounting mechanism 8 includes a base 81. Two connecting plates 83 are fixedly connected to the upper end of the base 81. Both of the two connecting plates 83 have a structure that is narrower at the top and wider at the bottom. A connecting shaft 84 is installed and connected by the two connecting plates 83. A reinforcing plate 85 is commonly connected to the front ends of the two connecting plates 83.
