Pump comprising vacuum pump assembly can only be isolated simple disadvantage is that the damper of the device is made of rubber material
High-frequency vibration cannot be isolated in low-frequency vibration, and vehicle environment is poor, and usage experience is ineffective, be easy to make vacuum pump and damper
At damage.
Invention content
The present invention is that rubber material is made, simple low frequency can only be isolated shakes to solve damper in the prior art
It is dynamic, high-frequency vibration cannot be isolated, be easy to cause that vehicle environment is poor, usage experience is ineffective, easy to vacuum pump and damper
The deficiency for causing damage, low-frequency vibration and high-frequency vibration can be reduced, improve vehicle environment, usage experience effect by providing one kind
Good, the spiral vacuum pump two stage impact damper good to vacuum pump and damper protecting effect.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of spiral vacuum pump two stage impact damper includes outer skeleton, inner sleeve and the link of hollow form, the outer skeleton
Inner end is equipped with level-one shock-absorbing sleeve and two level shock-absorbing sleeve, and the both ends of the inner sleeve are each passed through the upper and lower ends face of outer skeleton, institute
The upper first both ends and the upper and lower ends face of outer skeleton for stating inner sleeve are rotatablely connected, the level-one shock-absorbing sleeve and two level shock-absorbing sleeve spiral
Between inner sleeve and outer skeleton, the link is pyramidal, the upper surface of the link and outer skeleton for Cross Trade
Lower face links into an integrated entity shape.The damper of the present invention includes outer skeleton, inner sleeve and the several parts of connector, in outer skeleton and
Level-one shock-absorbing sleeve and two level shock-absorbing sleeve are provided between inner sleeve, for high frequency caused by vacuum pump and dynamical system, low
Frequency vibrations carry out damping, and vacuum pump is attached fixation across inner sleeve, and the upper and lower end face of inner sleeve and outer skeleton is rotatablely connected,
Prevent the fine rotation that vacuum pump is occurred when shaking, and caused by loosening between outer skeleton and inner sleeve, make to subtract
It shakes effect to decline, be used for and the connecting pin of vacuum pump is connect with the link into an integrated entity link of shape of the lower face of outer skeleton.
Preferably, the level-one shock-absorbing sleeve is rectangular rubber layer, the two level shock-absorbing sleeve is rectangle PE cotton layers, the rubber
A side of glue-line and PE cotton layers is connected with the side wall of inner sleeve, and rolled formed helical cylindrical.Rectangular rubber layer
Level-one shock-absorbing sleeve can effective damping low-frequency vibration, and more enough effective damping high-frequency vibrations of two level shock-absorbing sleeve of rectangle PE cotton layers,
By rubber layer and PE cotton layer overlappings and rolled formed helical cylindrical, prevent it from occurring to loosen and reduce damping effect, and subtract
Uniform in effect is shaken, if slight rotation occurs when shaking for vacuum pump, the damping device of helical cylindrical can be along
Or it prevents from loosening against rotation direction.
Preferably, the upper surface of the outer skeleton has been connected by screw end cap, one end through end of the inner sleeve
The upper surface of lid.Detachable end is convenient for internal damping device repair and replacement.
Preferably, being equipped with several rollers between the inner sleeve and end cap.Roller realize inner sleeve and end cap it
Between rotation connection, prevent abrasion loosen, reduce damping effect.
Preferably, the lower face of the link is equipped with spring liner, the link, which passes through, bolt, the bolt
Lower end pass through spring liner.The spring liner of link lower end prevents damper from pine occurs with vacuum pump in long-term vibrations
It is dynamic.
Therefore, a kind of spiral vacuum pump two stage impact damper of the invention has the following advantages：Low-frequency vibration can be reduced
And high-frequency vibration, improve vehicle environment, usage experience effect is good, good to vacuum pump and damper protecting effect.
