Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a composite sound insulation pad based on foamed PVC and sponge comprises a polished PVC plate 1, the polished PVC plate 1 is used for supporting an internal structure and facilitating installation of a device, an outer foamed PVC plate 2 is fixedly connected to the top of the polished PVC plate 1, the outer foamed PVC plate 2 is used for performing final sound insulation on noise to reduce transmission of sound volume, a sound insulation sponge 3 is fixedly connected to the top of the outer foamed PVC plate 2, the sound insulation sponge 3 has a main sound insulation and absorption effect due to a fluffy structure therein and also has a damping effect, an inner foamed PVC plate 4 is fixedly connected to the top of the sound insulation sponge 3, the inner foamed PVC plate 4 is used for primarily absorbing noise, an inner baffle 5 is fixedly connected to the top of the inner foamed PVC plate 4, the inner baffle 5 is used for supporting an internal structure and simultaneously can be in contact with an outer surface of a compressor, thereby the noise that makes the compressor can be transmitted to the syllable-dividing pad on, sound absorption groove 6 has been seted up on the surface of interior baffle 5, sound absorption groove 6 is used for making the noise can transmit to 3 inside messenger's noises of giving sound insulation and is absorbed to soundproof effect has been reached.

Specifically, the one side that outer foaming PVC board 2 was kept away from to polishing PVC board 1 is the smooth surface, and the one side that polishing PVC board 1 is close to outer foaming PVC board 2 is the mat surface.

Through above-mentioned technical scheme, the messenger that polishing PVC board 1's rough surface can be fine is fixed on outer foaming PVC board 2, and smooth surface can be fine installs with the oxygen-absorbing machine is inside.

Specifically, outer foaming PVC board 2 and inlayer foaming PVC board 4 are the foam particle and constitute, and the surface of outer foaming PVC board 2 and inlayer foaming PVC board 4 is the mat surface, and the structure is fluffy.

Through above-mentioned technical scheme, outer foaming PVC board 2 that the foam particle is constituteed can make and have the clearance between the outer foaming PVC board 2 to through the transmission direction of clearance absorbed noise and change noise, thereby reach preliminary syllable-dividing effect.

Specifically, the outer surface of the inner layer foamed PVC plate 4 is provided with a through hole, and the through hole extends to the outer surface of the sound insulation sponge 3.

Through above-mentioned technical scheme, the through hole on 4 surfaces of inlayer foaming PVC board can make the noise transmit to the inside of the sponge 3 that gives sound insulation to the fluffy structure in the middle of the sponge 3 that makes sound insulation can absorb the noise.

Specifically, the inner partition 5 is made of PVC, and the thickness of the inner partition 5 is equal to the thickness of the polished PVC plate 1.

Through the technical scheme, the material of the inner baffle plate 5 can lighten the whole weight, meanwhile, the thickness of the inner baffle plate 5 is equal to that of the polishing PVC plate 1, so that the stress on two sides of the device is uniform, and the device is prevented from deforming due to the fact that the thickness of one side of the device is different after the device is used for a long time.

Specifically, the number of the sound absorption grooves 6 is several, and the sound absorption grooves 6 all penetrate through the surface of the inner partition plate 5 and extend to the surface of the inner foamed PVC plate 4.

Through above-mentioned technical scheme, inhale the reflection direction that sound groove 6 can change the noise propagation, make the mixed and disorderly echo of avoiding producing of propagation direction of noise, also enable the surface that the noise direct transmission reaches inlayer foaming PVC board 4 simultaneously by preliminary syllable-dividing, and carry out complete syllable-dividing through sound-insulating sponge 3 at last.

When using, place the inside at the oxygen uptake machine with whole compound sound insulating pad, be used for around the compressor with fill up the bottom at the compressor, produced noise when the compressor work is earlier through the propagation direction that inhales 6 changes the noise of sound absorption groove simultaneously with the noise transmission to the position of the inner layer foaming PVC board 4 of inner baffle 5 bottom by preliminary absorption, the noise is carried out a large amount of absorptions by sound insulation sponge 3 afterwards, remaining noise is carried out ultimate absorption by outer foaming PVC board 2, thereby realize the sound insulation effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
