The utility model aims at providing a stable in structure, give sound insulation effectual, long service life's novel metal door.

The purpose of the utility model is realized like this: a novel metal door comprises an outer door plate, an inner door plate and an outer wrapping edge, wherein an installation cavity is formed among the outer door plate, the inner door plate and the outer wrapping edge, a sound insulation layer is filled in the installation cavity and comprises a first sound absorption sponge layer, a micropore layer and a second sound absorption sponge layer, and a protection wrapping edge is arranged on the outer wall of the sound insulation layer; the outer door plant all is equipped with a plurality of sound absorbing cover with interior door plant outside, sound absorbing cover includes frame, upper end cover and lower extreme cover, and the frame is inside to be equipped with and to hold the chamber, and frame upper portion is located to the upper end cover, and the lower extreme cover is located the frame lower part, is equipped with the through-hole on upper end cover and the lower extreme cover respectively, holds the intracavity and is equipped with a plurality of sound particles of inhaling.

Preferably, the sound-absorbing particles have a diameter of 0.2 to 0.5 mm.

Preferably, the number of the through holes arranged on the upper end cover and the lower end cover is 180-480 meshes respectively.

Preferably, the sound-absorbing cover is rectangular, circular or triangular in shape.

Preferably, the frame is made of sponge.

Preferably, the upper end cover and the lower end cover are made of gauze.

Preferably, the material of the microporous layer adopts superfine glass wool or mineral wool.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses a sound-absorbing cover double sound insulation that the puigging and outer door plant and the interior door plant outside of metal door through installation intracavity installation set up reaches best syllable-dividing effect, avoids the user to receive noise disturbance.

Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1-4, a novel metal door comprises an outer door panel 1, an inner door panel 2 and an outer wrapping edge 3, wherein an installation cavity is formed between the outer door panel 1, the inner door panel 2 and the outer wrapping edge 3, a sound insulation layer 5 is filled in the installation cavity, the sound insulation layer 5 comprises a first sound absorption sponge layer 6, a micro-porous layer 7 and a second sound absorption sponge layer 8, and a protective wrapping edge 9 is arranged on the outer wall of the sound insulation layer 5; the outer door plant 1 and the interior door plant 2 outside all are equipped with a plurality of sound-absorbing cover 10, sound-absorbing cover 10 includes frame 11, upper end cover 12 and lower end cover 13, and frame 11 is inside to be equipped with and to hold chamber 14, and upper end cover 12 locates frame 11 upper portion, and frame 11 lower part is located to lower end cover 13, is equipped with the through-hole on upper end cover 12 and the lower end cover 13 respectively, holds the intracavity and is equipped with a plurality of sound particles 15 of inhaling.

The sound-absorbing cover 10 that this technical scheme's metal door installed through the puigging 5 of installation intracavity and outer door plant 1 and the interior door plant 2 outside setting gives sound, reaches the best syllable-dividing effect, avoids the user to receive noise interference. When the noise penetrates into the second sound absorption sponge layer 8 through the first sound absorption sponge layer 6, the air vibration in the gap of the second sound absorption sponge layer 8 can be caused, and due to the viscous resistance of the air and the friction between the air and the hole wall, a part of sound energy is converted into heat energy and is consumed, and meanwhile, the outer door plate 1 or the inner door plate 2 can separate part of sound energy, so that a good sound insulation effect is guaranteed. Through adopting the sound sponge material of inhaling with frame 11, upper end cover 12 and lower end cover 13 adopt the gauze material, make the cross cutting that the whole cover body can be accurate go out arbitrary shape to through set up a plurality of sound granule 15 of inhaling in inhaling sound sponge frame 11, make it have better sound effect of inhaling, and its simple structure, application scope is wide, and sound effect of inhaling is good.

Preferably, the sound-absorbing particles 15 have a diameter of 0.2 to 0.5 mm.

Preferably, the number of the through holes formed in the upper end cap 12 and the lower end cap 13 is 180 to 480.

Preferably, the sound-absorbing cover 10 is rectangular, circular, or triangular in shape.

Preferably, the frame 11 is made of sponge.

Preferably, the upper end cap 12 and the lower end cap 13 are made of gauze.

Preferably, the material of the microporous layer 7 is ultra-fine glass wool or mineral wool.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
