Description

A dual soundproof structure

The present invention relates to a double soundproof structure, and more particularly, a soundproof frame having a matrix-arrayed exhaust chamber is mounted on a sound insulation frame to form a exhaust space at the rear, thereby canceling sound absorption in the exhaust chamber and noise in the exhaust chamber. It is a double soundproof structure that can completely block noise.

In general, the soundproof structure is formed in the sound-absorbing material of the sound-absorbing material is attached to the wall formed by a plurality of grooves, was a simple primary soundproof structure that the sound-absorbing sound absorbing or sound-proofing.

However, the soundproof structure as described above is designed to block noise only in the soundproofing body, so that residual noise that is not extinguished by the soundproofing body is formed according to the degree of noise, and the residual noise cannot be removed, thereby causing resonance. There was a problem that can not be expected to shorten the life or effects over a certain value due to the phenomenon that may occur secondary.

The present invention has been devised in view of the above problems, so that the soundproof frame having an exhaust chamber for absorbing noise is arranged in a matrix so as to form an exhausting space capable of again extinguishing the residual noise induced by the exhaust chamber. Due to the double soundproof structure mounted on the sound insulation frame, the residual noise can be completely extinguished, and the secondary phenomenon caused by the residual noise is blocked in advance, and the purpose of the present invention is to provide a double soundproof structure that can effectively expect soundproofing.

In addition, the soundproof frame is provided with a rotating means to be rotated from the soundproof frame to the lower axis to provide a double soundproof structure that can be easily and efficiently cleaning the soundproof frame and sound insulation frame. .

The rotation means is positioned between each of the soundproof frames and the upper horizontal width is formed on the lower surface of the sound insulation frame is smaller than the lower horizontal width of the fastening groove formed in the thickness direction, the upper end of the body formed to be inserted into the fastening groove sound insulation Rotating body formed with a fastening protrusion on the side while protruding into the inner space of the frame, it comprises a fastening cavity formed in the front lower side of the side of the soundproof frame to fit the fastening projection of the rotating body.

The upper surface of the soundproof frame is inclined downward from the front surface so as to gradually widen the upper surface of the soundproof frame so as to smoothly rotate the soundproof frame by the pivoting means.

The coupling of the sound insulation frame and the sound insulation frame regulates the rotation of the sound insulation frame by engaging the slot formed in the longitudinal direction on the upper inner surface of the sound insulation frame with a plurality of coupling protrusions formed on the upper outer surface of the sound insulation frame.

In order to secure the coupling between the sound insulation frame and the sound insulation frame, the sound insulation frame further includes a plurality of coupling grooves formed in a thickness direction between exhaust chambers at rear ends, and the sound insulation frame further includes a plurality of coupling plates attached to the coupling grooves. do.

The exhaust chambers are arranged so as to have mutual stages on a horizontal line.

Hereinafter, a double soundproof structure according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view schematically illustrating a double soundproof structure according to a preferred embodiment of the present invention, FIG. 2 is a front view of the combined portion of FIG. 1, and FIG. 3 is a partial cross-sectional view taken along line II-II of FIG. 2. 4 is a partial cross-sectional view taken along the line IV-IV of FIG. 2.

As shown in Figures 1 to 4, the double soundproof structure 10 according to the present invention is the exhaust chamber 22, which is absorbed by noise is formed in the soundproof frame 30 in a matrix arrangement, the soundproof frame 30 is rotatably mounted to the sound insulation frame 40 by the rotation means 50 while the exhaust space 36 is formed in the rear.

The soundproof frame 30 has a plurality of coupling protrusions 34 formed on an upper outer surface, and the soundproof frame 40 has a slot 44 in a lengthwise direction on an upper inner surface thereof so that the coupling protrusion 34 is engaged. The combination of these (34, 44) is used as an auxiliary coupling of the sound insulation frame 30 and the sound insulation frame 40 also serves to regulate the rotation of the sound insulation frame (30).

The exhaust chamber 22 is discharged to the rear side while the front and rear through the rectangular shape of the front through the largest cross-section and the rear surface with the smallest cross-section along the inclined inclined surface is gradually eliminated, the noise introduced to the front gradually disappears, Residual noise passing through the exhaust chamber 22 is mutually canceled in the exhaust chamber 36 and completely disappears.

On the other hand, the rotation means 50 is for causing the sound-proof frame 30 is rotated downward from the sound-proof frame 40 in order to wash the sound-proof frame 30.

The rotation means 50 is positioned between each of the soundproof frames 30 mounted on the sound insulation frame 40 in a horizontal arrangement, and the upper horizontal width is smaller than the lower horizontal width on the lower surface of the sound insulation frame 40. While forming the fastening groove 52 formed in the thickness direction, and the upper end of the body 54a formed to be inserted into the fastening groove 52 protrudes into the sound insulation frame 40 internal space, the fastening protrusion 54b is formed on the side surface. It includes a rotating body 54, and a fastening cavity 56 formed in the lower front side of the side of the sound-proof frame 30 so that the fastening protrusion 54b of the rotating body 54 is fitted.
