The piston, the rubber ring, the spring, the sealing ring, the positioning screw, the air inlet, the needle valve and the rubber diaphragm valve plate are disposed inside the cylinder body, through holes are uniformly distributed on the piston, the periphery of the piston is sealed with the cylinder body through an O-shaped rubber ring, the rubber diaphragm valve plate is disposed on the upper portion of the piston and covered on the through holes, the sealing ring is arranged on the bottom portion of the cylinder body, the positioning screw penetrates through the sealing ring, the spring is disposed between the bottom portion of the piston and the upper portion of the sealing ring, the needle valve is disposed on the bottom portion of the positioning screw, and the air inlet is disposed on the positioning screw and arranged opposite to the needle valve. The damping frequency adjustable vibration absorber is simple in structure and high in stability.

Description

Vibration damping frequency-adjustable vibration damper
Technical field
The utility model relates to and a kind ofly is used to make a video recording or the adjustable shock of instrument system vibration damping, is specially a kind of vibration damping frequency-adjustable vibration damper.
Background technique
The vibration damping frequency of general vibration damper customizes according to the known environment vibration frequency range, the intensity of its load is to rely on the elastic strength of pressure spring to mate, or other elasticity original paper is realized: as rubber, compressed liquid, pressurized air etc.More than various vibration damper mechanism complexity, regulate difficulty, poor stability.
The model utility content
The utility model purpose is to provide a kind of vibration damping frequency-adjustable vibration damper at the defective that prior art exists.
The utility model adopts following technological scheme for achieving the above object:
The utility model vibration damping frequency-adjustable vibration damper, it is characterized in that comprising cylinder body and be arranged at the interior piston of cylinder body, rubber ring, spring, seal ring, positioning screwn, inlet hole, needle type valve and rubber membrane valve block, uniform through hole on the piston wherein, seal by rubber ring and cylinder body about piston, the rubber membrane valve block is arranged at the top of described piston and is covered on the described through hole, seal ring is arranged at the bottom of cylinder body, positioning screwn passes seal ring, between the bottom of piston and the top of seal ring spring is set, needle type valve is arranged at the bottom of positioning screwn, and inlet hole is arranged on the positioning screwn and with needle type valve and is oppositely arranged.
Described vibration damping frequency-adjustable vibration damper is characterized in that described rubber ring is the cylindrical rubber circle.
Described vibration damping frequency-adjustable vibration damper is characterized in that described cylinder body top also is provided with piston hole, and described piston hole edge also is provided with guard ring.
The utility model reaches by the stability of shock absorber part in vibration environment by the ratio of adjusting the upper and lower motion air mass flow of damper piston.Simple in structure, stability height.
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.
