Abstract
The utility model discloses an instrument bumper shock absorber, its characterized in that: including platform structure (6), platform structure (6) include rubber base (1), concave part (3), go up rubber pad (4) and spring (5), be equipped with rubber base (1) on platform structure (6), be equipped with convex part (3) on rubber base (1), be equipped with rubber pad (4) on convex part (3), be equipped with spring (5) in the platform structure, spring (5) fixed mounting is under screw thread through -hole (2), and screw thread through -hole (2) fixed mounting is on platform structure (6).
Description
Technical field
The utility model discloses a kind of vibration damper, refer more particularly to a kind of instrument vibration damper.
Background technique
Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump.Vibration damper is too soft, and vehicle body will vertical bounce, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.Be mainly used in the impact from vibration of main frame, subsidiary engine, various dynamic power machine and instrument and apparatus, play the effect reducing vibration, noise and prevent from impacting.Owing to there is the existing picture of self-vibration, frequency vibration during sky easily transmits in existing vibration damper, critical damping ratio generally only has 0.005, therefore poor for the isolating technique ability near resonant frequency; Noise is large, complex structure, and damping effect is poor, and installing/dismounting is complicated, the problems such as the life-span is short.
Model utility content
It is large that the technical problems to be solved in the utility model there is provided a kind of internal friction, and good damping effect, is conducive to crossing resonance region, attenuate high frequency vibration & noise, structure is simple, and damping effect is excellent, quality is little, and installation and removal are convenient, the instrument vibration damper that the life-span is long.
In order to solve the problems of the technologies described above, the utility model provides a kind of instrument vibration damper, it is characterized in that: comprise platform structure; Described platform structure comprises rubber base plate, recess, upper rubber pad and spring; Described platform structure is provided with rubber base plate, and rubber base plate is provided with protuberance, and protuberance is provided with rubber pad; Be provided with spring in described platform structure, under spring is fixedly installed in tapped through hole, tapped through hole is fixedly installed on platform structure.
As further improvement of the utility model, the long 70mm of described instrument vibration damper, high 40mm.
As further improvement of the utility model, described instrument vibration damper adopts rubber as material.
Adopt said structure, its beneficial effect is: the utility model adopts rubber as material, and internal friction is large, good damping effect, be conducive to crossing resonance region, attenuate high frequency vibration & noise, structure is simple, and damping effect is excellent, the plurality of advantages such as quality is little, and installation and removal are convenient, and the life-span is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of instrument vibration damper of the utility model.
In figure: 1-rubber base plate, 2-tapped through hole, 3-recess, the upper rubber pad of 4-, 5-spring, 6-platform structure.
Embodiment
Below in conjunction with drawings and Examples, explanation is further explained to the utility model.
As shown in Figure 1, a kind of instrument vibration damper, is characterized in that: comprise platform structure 6; Described platform structure 6 comprises rubber base plate 1, recess 3, upper rubber pad 4 and spring 5; Described platform structure 6 is provided with rubber base plate 1, and rubber base plate 1 is provided with protuberance 3, and protuberance 3 is provided with rubber pad 4; Be provided with spring 5 in described platform structure, spring 5 is fixedly installed in tapped through hole 2 times, and tapped through hole 2 is fixedly installed on platform structure 6; The long 70mm of described instrument vibration damper, high 40mm; Described instrument vibration damper adopts rubber as material.
The utility model adopts rubber as material, the feature of rubber is that existing elastomeric state has again high glutinous state, the elasticity of rubber likes that the change that you cross produces by its coiled molecule conformation, between rubber molecule, interaction can hinder the motion of molecular chain, show stickiness feature, so that stress and strain is often in non-equilibrium state.This curling long-chain molecule structure of rubber and the more weak secondary power of intermolecular existence, make rubber material present unique viscoelasticity energy, thus have good damping, sound insulation and shock-absorbing capacity.
The plurality of advantages such as the utility model internal friction is large, and good damping effect, is conducive to crossing resonance region, attenuate high frequency vibration & noise, and structure is simple, and damping effect is excellent, and quality is little, and installation and removal are convenient, and the life-span is long.
Any employing and the similar vibration damper designed by technical characteristics of the utility model will fall within protection domain of the present utility model.
