Several cavitys are offered in first shock ring and the second shock ring, and spring is placed in the cavity.
Further, the outer end face of the inner face fitting damping round platform of first shock ring, second shock ring
Inner face is bonded the outer end face of the first shock ring.
Further, the peripheral surface of the damping round platform, the first shock ring and the second shock ring is equipped with form friction pattern.
Further, one end of the lower panel is connected with the first connecting plate, the top panel far from the first connecting plate one
End is equipped with the second connecting plate, and first connecting plate is equal with the width of the second connecting plate.
Further, the thickness of second connecting plate is equal to the thickness of top panel, second connecting plate and top panel
It is integrally formed.
Further, the thickness of first connecting plate is equal to the thickness of lower panel, first connecting plate and lower panel
It is integrally formed.
With the above structure, the utility model is compared to the prior art advantageously：The rubber face of the application
Elastic supporting bar on plate can not only play a supportive role and can carry out first time noise reduction damping, and the second shock ring can carry out
Second of damping, the first shock ring can carry out third time damping, and damping round platform can carry out the 4th damping, while in damping
The cavity for placing spring is offered in round platform, the first shock ring and the second shock ring, can further function as damping noise reduction in this way
It acts on and its damping effect is more preferable, while the abrasion that can effectively slow down damping round platform increases service life, prolongs the service life；
The peripheral surface of damping round platform, the first shock ring and the second shock ring be equipped with form friction pattern in this way and can increase friction avoid because by
