The invention provides a fluid viscous damper with a working switch, and belongs to the technical field of structural energy consumption to absorb shock (vibration). The fluid viscous damper of the working switch is characterized in that a fixed connecting rod is arranged between a piston rod end connecting rod and a fixed end on one side of the typical fluid viscous damper, an inner sleeve rod and a cylindrical outer sleeve are relatively sliding, and the fixed connecting rod prevents a damper piston and an outer wall of a hydraulic cylinder from relatively moving; when the displacement of the inner sleeve rod reaches a stated maximum displacement value, a brake switch on a pop-up stopper in the outer sleeve is contacted, and the pop-up stopper pops up and clamps a brake head of an inner sleeve rod end together with a fixed stopper, so that the inner sleeve rod is locked and does not slide relative to the outer sleeve, the fixed connecting rod is stressed and destroyed by an impact force, and the damper begins to consume energy for shock absorption. The fluid viscous damper with the working switch has the effects and advantages that the fluid viscous damper is expected to be applied to structures such as a suspension bridge provided with a central buckle or a cable-stayed bridge provided with a floating system, the service life of the damper can be prolonged, and the damper is enabled to play a role of correspondingly consuming energy for shock absorption when a large shock occurs.

The technical scheme of the reciprocating mechanism is that: the reciprocating mechanism comprises an annular piston and a piston seat, wherein the inner surface of the annular piston is provided with an inner sealing circular groove which is coaxial with the piston; an inner lip-shaped sealing ring is arranged in the inner sealing circular groove; the outer surface of the annular piston is provided with an outer sealing circular groove which is coaxial with the piston; an outer lip-shaped sealing ring is arranged in the outer sealing circular groove; after improvement, the inner surface of the piston is provided with an inner oil guide groove which is communicated with the inner sealing circular groove; the outer surface of the piston is provided with an outer oil guide groove which is communicated with the outer sealing circular groove; and both the inner oil guide groove and the outer oil guide groove are positioned in an annular hydraulic oil cavity which is formed by enclosing the piston, the piston seat, the inner lip-shaped sealing ring and the outer lip-shaped sealing ring. The low-pressure reciprocating mechanism of the engineering machinery chassis can ensure the sealing effect thereof under the high temperature working condition and the low temperature working condition and completely prevent the occurrence of oil leakage phenomenon.
