Specific implementation mode

[0019] The following further describes in detail the implementation mode of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0020] Please refer to Figures 1-5 , the present utility model: a household high-strength sound-insulating and flame-retardant environmental protection wooden door, including a wooden door body 1, the wooden door body 1 is made of natural wood, which is more environmentally friendly. A middle partition board 2 is fixedly connected inside the wooden door body 1. Strengthening layers 3 are fixedly connected between the two sides of the middle partition board 2 and the opposite inner groove walls of the wooden door body 1. Sound absorption holes 4 are penetrated on the surface of the middle partition board 2. A sound absorption channel 5 is provided in the inner groove of the middle partition board 2. The sound absorption channel 5 is communicated with the sound absorption holes 4. The sound absorption channel 5 and the sound absorption holes 4 guide the sound energy, so that the sound is consumed during the propagation process, thereby completing the high-efficiency sound insulation of the wooden door body 1 and improving the sound insulation effect of the wooden door body 1, enhancing the comfort of the user's residence. A fire extinguishing box 6 is fixedly connected to the outer wall of the middle partition board 2. The fire extinguishing box 6 is filled with a flame retardant. Through the flame retardant gas generated by the flame retardant, the oxygen required for combustion is physically isolated, thereby realizing the fire protection and flame retardant effect of the wooden door body 1 and ensuring the safety of the user. Triangular through holes 9 are penetrated on the surface of the strengthening layer 3. The triangular through holes 9 are arranged in an array and meshed evenly. Utilizing the stable support characteristics of the triangle, the strengthening layer 3 provides more effective help for improving the strength of the wooden door body 1, and improves the use stability and safety of the wooden door body 1.

[0021] A sound absorption strip 7 is fixedly connected to the inner groove wall of the sound absorption channel 5. A sound absorption convex tooth 8 is fixedly connected to the surface of the sound absorption strip 7. Both the sound absorption strip 7 and the sound absorption convex tooth 8 are made of sponge material. The sound absorption convex teeth 8 on the surface of the sound absorption strip 7 reflect and block the sound in the sound absorption channel 5, so that the sound energy is consumed, and the noise is reduced, realizing the high-efficiency sound insulation effect of the wooden door body 1 and ensuring the comfort of the indoor environment after the wooden door body 1 is used.

[0022] A plastic film 10 is fixedly connected to the opening position of the fire extinguishing box 6. A fire ignition column 11 is fixedly connected to the center position of the plastic film 10. The fire ignition column 11 is composed of paper and cotton wool wound around it. After a fire occurs, when the flame burns to the wooden door body 1, the surface of the wooden door body 1 is at a high temperature. When the temperature reaches 120°, it reaches the ignition point of the fire ignition column 11. At this time, the fire ignition column 11 can burn, and burn the plastic film 10, exposing the flame retardant inside the fire extinguishing box 6 for flame retardance. Or when the flame directly burns to the fire ignition column 11 and the plastic film 10, the flame retardant inside the fire extinguishing box 6 can also contact the high temperature and volatilize for flame retardance. The flame retardant filled inside the fire extinguishing box 6 is made by mixing a halogen-free flame retardant and a halogen-containing flame retardant. The flame retardant gasifies when heated, and the gasified gas is a flame retardant gas, which can isolate the oxygen around the wooden door body 1, so that the flame cannot continue to burn the wooden door body 1, thereby achieving flame retardance and ensuring the safety of the people in the room on the side of the wooden door body 1 away from the fire.

[0023] The working principle of the present utility model is: when in use, the wooden door body 1 is installed on the door frame of the room door. During subsequent use, when there is more noise or a louder sound on one side of the wooden door body 1, at this time, the sound passes through the wooden door body 1 and enters the interior. The sound enters the middle partition 2 inside the wooden door body 1, and then the sound passes through the sound absorption holes 4. Then most of the sound enters the sound absorption channel 5. Subsequently, the sound is conducted inside the sound absorption channel 5, and the sound absorption convex teeth 8 on the surface of the sound absorption strip 7 block and reflect the sound, thereby reducing the sound energy, and thus achieving the sound insulation effect, making the sound insulation effect of the wooden door body 1 better;

[0024] A reinforcing layer 3 is arranged between the interior of the wooden door body 1 and the middle partition 2. The reinforcing layer 3 utilizes the principle of the stable triangle support, and is provided with mutually meshing and staggered triangular through openings 9, so that the entire reinforcing layer 3 presents a triangular honeycomb shape, which can strengthen the structural strength of the wooden door body 1, enabling the wooden door body 1 to better resist impact and reduce the damage of the wooden door body 1. When a fire occurs indoors, when the fire spreads to the position of the wooden door body 1 and the flame burns the side of the wooden door body 1 close to the fire, at this time, the fire ignition column 11 burns when heated. At this time, the fire ignition column 11 ignites the plastic film 10. After the plastic film 10 is quickly burned out, at this time, the flame retardant inside the fire extinguishing box 6 gasifies when heated, generating a flame retardant gas that isolates oxygen, so that there is no oxygen for combustion around the wooden door body 1, thereby blocking the combustion and achieving flame retardance, ensuring the safety of the room on the other side of the wooden door body 1.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
