Abstract
The utility model relates to a foamed plastic damping block which comprises a damping rubber block. The utility model is characterized in that a layer of sound absorbing sponge is stuck to one face of the flat damping rubber block, each air chamber of the sound absorbing sponge is provided with at least one hole connected with other air chambers and each air chamber of the sound absorbing sponge is in the shape of a honeycomb. The utility model has the advantages that the foamed plastic damping block performs a damping function and absorbs and reduces noise sent out by vibration.
Description
Technical field
The utility model relates to a kind of Vibration damping block, particularly a kind of foamed plastics Vibration damping block.
Background technique
Main frame at air-conditioning equipment causes the casing vibration because of the operation of compressor at present, and vibration will be sent bigger low frequency noise, therefore on casing, be pasted with vibration isolation rubber for vibration damping, but send bigger low frequency noise owing to the casing of air conditioner and pipeline always can vibrate, therefore be pasted with vibration isolation rubber merely and carry out vibration damping and can't reduce noise.
Summary of the invention
The purpose of this utility model is that the main frame that solves air-conditioning equipment in the prior art causes the casing vibration because of the operation of compressor, and vibration will be sent bigger low frequency noise, therefore on casing, be pasted with vibration isolation rubber for vibration damping, but send bigger low frequency noise owing to the casing of air conditioner and pipeline always can vibrate, therefore being pasted with vibration isolation rubber merely carries out the problem that vibration damping can't reduce noise.The utility model design foamed plastics Vibration damping block, comprise the vibration isolation rubber piece, it is characterized in that: be pasted with one deck sound-absorbing sponge on smooth vibration isolation rubber piece one side, each air chamber of sound-absorbing sponge has at least a hole to link to each other with other air chamber, and the air chamber of sound-absorbing sponge is a honeycombed.The utility model has the advantages that and on the basis of vibration damping, to absorb and to reduce the noise that vibration is sent.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is an air chamber structure schematic representation of the present utility model,
Comprise vibration isolation rubber piece 1 among the embodiment figure, it is characterized in that: on smooth vibration isolation rubber piece 1 one side, be pasted with one deck sound-absorbing sponge 2, each air chamber 3 of sound-absorbing sponge 2 has at least a hole 4 to link to each other with other air chamber 3, and the air chamber 3 of sound-absorbing sponge 2 is a honeycombed.During use vibration damping sound-absorbing rubber damping piece is sticked on the casing, can reduce shell vibration, can also absorb the noise that vibration is sent by the air chamber 3 of the mutual perforation on the sound-absorbing sponge 2 in addition.
Claims (3)
