As a kind of preferred structure, described damper regulator comprises motionless body and the rotor that turns 90 °, has a through hole in the rotor, and rotor is provided with a handle outward.
As a kind of preferred structure, there is the circulation gap in the bottom surface that described piston lower end has surface area to strengthen between the bottom surface of piston and the inwall of damped cylinder.
As a kind of preferred structure, an end of described pipeline is positioned at the top of the bottom surface of piston, and the other end of pipeline is positioned at the below of the bottom surface of piston.
As a kind of preferred structure, when moving down into, described top board touches damped cylinder, and the bottom surface of piston does not contact base plate.
As a kind of preferred structure, described base plate and top board are rectangle, and vibration-isolating spring is four and is distributed in base plate and four angles of top board.
The utility model has following advantage with respect to prior art: this variable-damping shock solves prior oscillating damper and vibration isolator, and under the certain situation of resisting medium, the damping function effect is constant, the constant problem of damping function during the vibration frequency working conditions change.The utility model is under the certain situation of resisting medium, and damping function is variable, can meticulous continuous adjusting, satisfy the frequent occasion demand of various vibration working conditions change.
Flow in circulation gap between the bottom surface that resisting medium of the present utility model can be by piston and the inwall of damped cylinder, also can flow by the pipeline of damped cylinder side, and damper regulator can regulate opening and cutting out of pipeline, have a through hole in the rotor of damper regulator, when rotor rotates 90 °, can close through hole and pipeline, 90 ° of backward rotation can be opened through hole and pipeline.Therefore, by regulating the angle of swing of rotor, the size of the latus rectum that can meticulous continuous adjusting resisting medium flows changes damping function, changes the natural frequency of whole vibration damper, avoids the excited frequency of vibration source, avoids occurring resonance phenomenon.Vibration source has different vibration frequencies usually in the different time, adopts manually or the size of the mobile latus rectum of mechanical adjustment damper regulator, accurately controls damping function.
When damper regulator was opened, resisting medium both can flow in the circulation gap, also can flow by pipeline, and damping function this moment (damping force) is less;
When damper regulator cut out, resisting medium only can flow in the circulation gap, and damping function this moment (damping force) is bigger.
When machine startup, vibration frequency is lower, and Oscillation Amplitude is bigger, and the latus rectum that can adjust damper regulator is less, produces bigger damping function, makes the machine smooth starting; After the machine full speed running, vibration frequency is higher, and amplitude is less, and the latus rectum that then can adjust damper regulator is bigger, reduces damping function, obtains the favorable damping effect; When machine was prepared to shut down, the latus rectum that can adjust damper regulator in advance reduced, and produces bigger damping function, and the realization machine is steadily shut down.
Variable-damping shock of the present utility model can meticulous adjusting damping function, satisfies the frequent demand of various vibration working conditions change, and weakening vibration damping and vibration isolation effect is obvious, helps prolonging machine working life, reduces bad loss, improves ambient vibration and noise reduction environmental protection.
