Description of drawings
Fig. 1: the utility model section of structure.
Embodiment
Be elaborated below in conjunction with the technological scheme of accompanying drawing to model utility:
As shown in Figure 1, vibration damping frequency-adjustable vibration damper, it is characterized in that comprising cylinder body 1 and be arranged at piston 2 in the cylinder body 1, rubber ring 3, spring 4, seal ring 5, positioning screwn 6, inlet hole 7, needle type valve 8 and rubber membrane valve block 9, uniform through hole on the piston 2 wherein, seal by rubber ring 3 and cylinder body 1 about piston 2, rubber membrane valve block 9 is arranged at the top of described piston 2 and is covered on the described through hole, seal ring 5 is arranged at the bottom of cylinder body 1, positioning screwn 6 passes seal ring 5, spring 4 is set between the top of the bottom of piston 2 and seal ring 5, needle type valve 8 is arranged at the bottom of positioning screwn 6, and inlet hole 7 is arranged on the positioning screwn 6 and with needle type valve 8 and is oppositely arranged.
Described vibration damping frequency-adjustable vibration damper is characterized in that described rubber ring 3 is the cylindrical rubber circle.
Described vibration damping frequency-adjustable vibration damper is characterized in that described cylinder body 1 top also is provided with piston hole, and described piston hole edge also is provided with guard ring 10.
The utility model is applicable to the situation that vibration frequency is lower, and concrete working principle is as follows:
When piston 2 acts on cylinder body 1 when moving downward because of vibration wave, when piston 2 acts on cylinder body 1 when moving downward because of vibration wave, the rubber membrane valve block 9 on piston 2 tops on by piston 2 end faces the air-flow in the uniform aperture back down, the pressure that piston 2 overcomes from spring 4 moves downward downwards fast, when vibration wave is anti-phase, piston 2 moves upward, rubber membrane valve block 9 because of the effect of air pressure difference with little bore closure, piston 2 is owing to there is the seal action of rubber o-ring 3, the air inlet of piston 2 bottoms can only be by the vibration damper bottom the aperture 7 of positioning screwn 6 bottoms enter cylinder body 1 bottom by needle type valve 8, regulate needle type valve 8, be the speed that adjusting piston 2 rises, thus the frequency of okperation of regulating vibration damper.
