[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Combine the following Figures 1 to 3 The utility model is described in detail.

[0022] An environmentally friendly wooden door with sound insulation effect comprises a wooden door 1, a sound insulation layer 2 is arranged inside the wooden door 1, a sound absorption layer 201 is arranged on one side of the sound insulation layer 2, a sound silencing layer 202 is arranged on one side of the sound absorbing layer 201, a reflection cavity 203 is arranged inside the sound insulation layer 2 near the sound silencing layer 202, a reflection component is connected to the middle of the reflection cavity 203, the reflection component is elastically deformed under pressure, the sound silencing layer 202 also comprises a sound silencing hole 2021, the sound silencing hole 2021 is arranged in the middle of the sound silencing layer 202, and the sound silencing hole 2021 is a plurality of holes arranged at a distance from each end of the sound silencing layer 202.

[0023] First, install the wooden door in the door frame of the building to isolate the inside and outside of the building.

[0024] At the same time, when noise is generated outside, the noise will penetrate into the sound insulation layer 2 through the wooden door. The sound will first pass through the reflection cavity 203, and then be dispersed and transmitted to the sound-absorbing layer 202 through the reflection plate 2031 in the reflection cavity 203. Then, the friction and resistance of sound propagation will be increased through the sound-absorbing holes 2021 of the sound-absorbing layer 202, thereby weakening the sound to a certain extent. The weakened sound will then be transmitted to the sound-absorbing layer 201 for further sound-absorbing treatment, so that the wooden door 1 can effectively isolate the external noise.

[0025] Furthermore, the reflection cavity 203 is a cavity connected to the sound insulation layer 2 and the silencer hole 2021. The reflection assembly includes a reflection plate 2031, an elastic telescopic rod 2032 and a support rod 2033. The reflection plate 2031 is arranged in the middle of the reflection cavity 203, the elastic telescopic rod 2032 is arranged between the two reflection plates 2031, and the support rod 2033 is arranged on one side of the elastic telescopic rod 2032. The reflection plates 2031 are plates arranged in an arc shape in groups of two, and one end of the reflection plate 2031 is connected to one side of the sound insulation layer 202, and one end of the reflection plate 2031 is connected to the sound insulation layer 202 near the opening of the sound insulation hole 2021. The elastic telescopic rod 2032 is arranged between the two reflection plates 2031, and one side of the elastic telescopic rod 2032 is connected to one side of the sound insulation layer 202 through the support rod 2033. The support rod 2033 is telescopically arranged, and one end of the support rod 2033 is connected to the elastic telescopic rod 2032 through a ring.

[0026] When the sound is propagated and reflected by the reflecting plate 2031, if the door is impacted from the outside, a certain pressure will be applied to the reflecting plate 2031, thereby forcing the elastic material of the reflecting plate 2031 itself to deform, and at the same time, it will be further bent along the arc bending direction. When the reflecting plate 2031 is further deformed and bent, because the concave and convex parts at its bottom are relative to the other reflecting plate 2031, the concave and convex parts of the two will move closer. When moving closer, the elastic telescopic rod 2032 connected between the two will be contracted, and then the reset elasticity of the elastic telescopic rod 2032 and the reset elasticity of the reflecting plate 2031 itself can buffer and offset the impact force to a certain extent, so that the wooden door 1 can be more stable when it is impacted by external force due to the reflecting cavity 203.

[0027] Finally, the elastic telescopic rod 2032 itself is connected through the support rod 2033 on one side, so that the elastic telescopic rod 2032 is more stable when contracted. At the same time, the elastic telescopic rod 2032 itself is also telescopically set to adapt to the deformation of the reflection plate 2031. At the same time, the support rod 2033 is connected to the elastic telescopic rod 2032 through a ring at one end, so that it will not affect the contraction of the elastic telescopic rod 2032.

[0028] The following is a specific implementation process of the utility model. First, the wooden door is installed in the door frame of the building to isolate the inside and outside of the building. At the same time, when noise is generated outside, the noise will penetrate into the sound insulation layer 2 through the wooden door. The sound will first pass through the reflection cavity 203, and then the reflection plate 2031 in the reflection cavity 203 will disperse the sound and transmit it to the sound-absorbing layer 202. Then, the sound-absorbing holes 2021 of the sound-absorbing layer 202 will increase the friction and resistance of sound propagation, thereby weakening the sound to a certain extent. Then, the weakened sound is transmitted to the sound-absorbing layer 201 for further sound-absorbing treatment, so that the wooden door 1 can well isolate the external noise. When the sound is propagated and reflected through the reflection plate 2031, if the door is impacted from the outside , which will exert a certain pressure on the reflective plate 2031, thereby forcing the elastic material of the reflective plate 2031 itself to deform, and at the same time, it will be further bent along the arc-shaped bending direction. When the reflective plate 2031 is further deformed and bent, because the concave and convex parts at its bottom are relative to the other reflective plate 2031, the concave and convex parts of the two will move closer together, and when moving closer together, the elastic telescopic rod 2032 connected between the two will be contracted, and then the impact force is buffered and offset to a certain extent through the reset elasticity of the elastic telescopic rod 2032 and the reset elasticity of the reflective plate 2031 itself, so that the wooden door 1 can be more stable when it is impacted by external force due to the reflective cavity 203.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
