Preferably, a plurality of groups of reinforcing components are further arranged between the wood panels, and each reinforcing component comprises a screw, a top disc and a nut; the screw rod penetrates through the multilayer partition sheets along the front-back direction, and two ends of the screw rod are fixedly connected with the top disc and are in contact with the wood panel through the top disc; and a pair of nuts are respectively matched on the screw rods on the two sides of each layer of the separation thin plate.

Preferably, the core sheet layer is a PVC sheet layer.

Preferably, the number of the separator sheets is at least three.

The beneficial effects of the utility model are concentrated and are embodied in: the noise can be effectively blocked and consumed. Particularly, the utility model is provided with a plurality of layers of partition sheets, the closed air sound-proof cavity formed between two adjacent layers of partition sheets can effectively prevent the sound from spreading, and the long felt layer arranged on the surface of the partition sheet can consume the energy carried in the sound by the swinging of the long fiber; the sound absorption sponge layer can effectively absorb noise. Therefore, the utility model discloses a block, consume, absorb multiple mode and combine together and get rid of the noise, have fabulous syllable-dividing noise reduction effect.

fig. 2 is an enlarged view of a portion a in fig. 1.

Detailed Description

A soundproof door panel as shown in fig. 1-2 includes two wood panels 1 parallel to each other and a rectangular frame 2 interposed between the wood panels 1, and the wood panels 1 are designed to have a specific shape according to specific needs, but are generally rectangular. The wood panel 1 is bonded with the frame body 2, of course, bolt connection, rivet connection and the like are available, the inner surface of the wood panel 1 is provided with the sound-absorbing sponge layer 3, the sound-absorbing sponge layer 3 is generally a rubber-plastic sponge plate, the thickness of the sound-absorbing sponge layer is about 1-1.5cm, and the sound-absorbing sponge layer is directly bonded on the wood panel 1.

As shown in fig. 2, a plurality of layers of parallel partition sheets 4 are disposed in the frame 2 along the front-back direction, i.e., the left-right direction in fig. 1. Generally, the number of the separation sheets 4 is at least three, but more layers may be provided, and the number of the separation sheets 4 is designed according to the required sound insulation level, and the greater the number of the separation sheets 4, the better the sound insulation effect.

The partition sheets 4 form air sound-insulating chambers 5 therebetween, and in fig. 2, if the number of the partition sheets 4 is three, the number of the air sound-insulating chambers 5 is 2. The separating sheet 4 is composed of a core layer and a long felt layer adhered to the surface of the core layer, and the longer the long fiber of the long felt layer is, the more obvious the energy consumption in the sound is in the vibration process, and usually not less than 0.5 cm. The felt layer is also attached to the core layer by bonding, riveting, or the like. The core board layer is a PVC board layer or a thin wood board layer and the like.

In order to improve the stability of the installation of the separation thin plates 4, a circle of installation strip 6 is arranged on the inner wall of the frame body 2, and a plurality of circles of annular grooves are formed in the inner wall of the installation strip 6 corresponding to the number of the separation thin plates 4. The groove is matched with the separating thin plate 4, and the edge of the separating thin plate 4 is clamped in the groove.

The utility model is provided with a plurality of layers of separating thin plates 4, the closed air sound-proof cavity 5 formed between two adjacent layers of separating thin plates 4 can effectively prevent the sound from spreading, and the long felt layer arranged on the surface of the separating thin plate 4 can consume the energy carried in the sound by the swinging of long fiber; the sound-absorbing sponge layer 3 can effectively absorb noise. Therefore, the utility model discloses a block, consume, absorb multiple mode and combine together and get rid of the noise, compare with traditional single mode, have fabulous syllable-dividing noise reduction effect.

As for the raw wood panel 1, since the price of the wood panel 1 is relatively expensive, the thickness of the wood panel 1 may be reduced in order to reduce the cost, and the wood panel 1 should be supported to some extent in order to maintain the strength of the whole. As shown in fig. 2, a plurality of groups of reinforcing components are further arranged between the wood panels 1, and each reinforcing component comprises a screw 7, a top disc 8 and a nut 9. The screw 7 penetrates through the multilayer partition thin plate 4 along the front-back direction, and two ends of the screw 7 are fixedly connected with the top disc 8 and are in contact with the wood panel 1 through the top disc 8. A pair of nuts 9 are respectively matched on the screw rods 7 on the two sides of each layer of the separation thin plate 4. The reinforcing component can support the wood panel 1, and the anti-collision performance of the wood panel is improved. At the same time, the reinforcing assembly also maintains the stability of the separator sheets 4 against deformation.
