System frequency, the noise inside its pipe and resonance noise is set to reduce or disappear, so as to realizing vibration and noise reducing.Further,
Due to setting multiple fins on the inwall of rubber sleeve so that the inwall of rubber sleeve forms laciniation, so, when clip is held tightly
Afterwards, the fin of the inwall of rubber sleeve is in contact with air-conditioning duct, and is squeezed and is deformed, the crushed element filling of fin
Into the gap between two fins, so as to avoid excessive compression of the rubber sleeve to air-conditioning duct, air-conditioner pipe will not be caused
Road deforms.Simultaneously as between adjacent lugs there is gap can absorb the deformation of fin, so as to so that fin have it is larger
Deflection, so, in air-conditioning work, no matter air-conditioning duct is cooled and diameter diminishes, or heated diameter becomes big, can
Made up by the deflection of rubber sleeve inwall fin, ensure that fin is in contact with pipeline all the time, avoid rubber sleeve from air-conditioning
Come off on pipeline, improve the reliability and stability used.
Further, there is circumferentially arranged annular groove, the annular groove is located on the outer wall of the rubber sleeve
The middle part of the rubber sleeve axial direction；The width of the annular groove is consistent with the width of the clip.
Using said structure, using the annular groove clip can be made to be fixed on the middle part of rubber sleeve all the time, avoided long-term
During use, vibrated by air-conditioning duct, clip is relatively moved or even is come off with rubber sleeve, be advantageous to improve what is used
Reliability.
Further, there are multiple axially disposed accommodating holes, the accommodating hole is evenly distributed on the rubber sleeve
Set；The balancing weight is in the form of a column, and is removably inserted into the accommodating hole.
So, the counterweight number of blocks inserted by adjusting in accommodating hole, thus it is possible to vary the overall weight of vibration absorber, so as to
Specific aim adjustment can be carried out according to the requirement of different pipelines, be advantageous to improve the effect of vibration damping.
Further, the one end of the accommodating hole outwardly is horn-like.
So, the inserting of balancing weight can be facilitated.
Further, the accommodating hole along the rubber sleeve axially through setting.
After inserting accommodating hole due to balancing weight, in the presence of clip, the frictional force of the two is larger, it is not easy to by balancing weight
Pulled from accommodating hole.It is in through hole that accommodating hole, which is set, then can using other instruments by balancing weight from the another of accommodating hole
End ejection.It is easy to the dismounting of balancing weight.
Further, there is the groove that radially breach described in face is set, the groove on the inwall of the rubber sleeve
Along the rubber sleeve axially through setting；Small 3~the 5mm of the thickness of rubber sleeve described in the depth ratio of the groove.
So, the wall thickness that rubber sleeve is located at groove is 3~5mm, and it is an entirety that can either ensure rubber sleeve, can be with
Bend in this place, rubber sleeve is opened from indentation, there.So, vibration damping can be installed or removed in the case of not detaching pipelines
Device, dismounting are more convenient.
Further, the material of the balancing weight is iron.
In summary, the utility model have it is simple in construction, be easy to dismount, can effectively reduce air-conditioning system operation when produce
Resonance and pipeline inner refrigerant caused by NVH noises, the advantages that reliability and stability are higher.
