[0002] Wooden doors refer to doors made from natural logs or engineered solid wood materials sourced from forests, such as walnut, teak, red oak, ash, and sapele. After processing, the finished doors are characterized by their resistance to deformation, corrosion, and cracks, as well as their heat insulation properties. They are scientifically processed through steps such as drying, cutting, planing, tenoning, drilling, high-speed milling, assembly, sanding, and painting.

[0003] For example, patent CN209687286U discloses a wooden door, including a door body, a processor, a formaldehyde detector, a silent fan, and an activated carbon adsorption plate. The door body has a cavity inside, and the processor, formaldehyde detector, silent fan, and activated carbon adsorption plate are all located inside the cavity. The formaldehyde detector and the silent fan both penetrate the outer wall of the door body and are located on the same plane of the door body. The cavity is used for air circulation, and ventilation holes are provided on the outer surface of the door body.

[0004] The aforementioned wooden door, due to its relatively simple structure, cannot meet the current demand for high sound insulation, resulting in a poor user experience. Furthermore, the door's strength needs improvement, as it may be damaged or deformed under external forces. Therefore, this application provides a high-strength noise-reducing wooden door to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-strength noise-reducing wooden door to address the problems that existing wooden doors, due to their relatively simple structure, cannot meet the current demand for high sound insulation, resulting in a poor user experience in daily use. Furthermore, the strength of these wooden doors needs improvement, as they may be damaged or deformed under external forces.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A high-strength noise-reducing wooden door includes a solid wood base plate, and a sound-insulating mechanism is installed on both sides of the solid wood base plate. The sound-insulating mechanism includes a pair of alloy plates and a pair of solid wood partitions, and a protective mechanism is installed on the outer edge of the pair of solid wood partitions. An anti-deformation mechanism is installed on the outer edge of one of the solid wood partitions, and a sound-insulating component is installed on the outer side of each of the pair of alloy plates.

[0008] Optionally, the alloy plates are symmetrically attached to both sides of the solid wood substrate.

[0009] Optionally, the sound insulation component includes EPS boards, which are disposed on the outer sides of the two alloy plates respectively. Sound insulation felt is glued to the outer sides of the two EPS boards respectively, and a solid wood partition is installed on the other side of the sound insulation felt.

[0010] Optionally, the EPS board and the sound insulation felt are glued together, and the EPS board and the sound insulation felt are symmetrically distributed along the vertical central axis of the solid wood substrate.

[0011] Optionally, the protective mechanism includes melamine paper, which is attached to the outside of the solid wood partition. The outside of the melamine paper is coated with a waterproof paint layer, and a protective film is attached to the outside of the waterproof paint layer.

[0012] Optionally, the melamine paper and the solid wood partition are glued together, and the dimensions of the melamine paper and the solid wood partition are approximately the same.

[0013] Optionally, the protective film is applied to the outer edge of the waterproof paint layer.

[0014] Optionally, the anti-deformation mechanism includes a first screw groove, which is distributed at the outer edge of one of the solid wood partitions. A rubber frame is embedded at the outer edge of the solid wood partition, and a second screw groove is provided around the side of the rubber frame. A positioning bolt is screwed into the middle of the second screw groove, and a decorative patch is attached to the outer side of the rubber frame.

[0015] Optionally, the first and second threaded grooves are of the same size, and both the first and second threaded grooves are threadedly connected to the positioning bolt.

[0016] Optionally, the outer side dimensions of the rubber partition are matched with the dimensions of the decorative patch.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by setting up a sound insulation mechanism, the alloy plate itself has the characteristics of high strength, corrosion resistance and high toughness. In this device, two alloy plates are placed between a pair of solid wood partitions and a solid wood base plate, which can greatly increase the overall strength of the wooden door. Secondly, EPS boards and sound insulation felts are placed adjacent to each other between the alloy plates and the corresponding solid wood partitions. The EPS board is expandable polystyrene board, which has the effects of sound insulation, shock resistance, heat insulation and moisture resistance. Combined with the sound insulation and damping shock absorption effects of the sound insulation felt itself, it can provide good protection for the wooden door.

[0019] By setting up protective mechanisms, the melamine paper on the outside of the solid wood partition has high strength, waterproof and wear-resistant characteristics, which further improves the overall hardness of the door panel. The waterproof paint layer on the outside of the melamine paper can isolate water in the air or in daily life, thereby preventing water from penetrating into the door panel and causing damage. The protective film on the outside of the paint layer mainly provides good scratch and abrasion protection.

[0020] By setting up an anti-deformation mechanism, the rubber frame on the inner edge of the solid wood partition located inside the solid wood base can act as a contact point with the door frame partition when people close the wooden door, avoiding potential damage to the panel caused by direct contact between the solid wood partition and the door frame partition each time the door is closed. The rubber frame is installed with the solid wood partition using positioning bolts and corresponding screw grooves, making it easy for people to disassemble, clean, or replace. The presence of decorative patches can provide a good concealing and aesthetic effect for the aforementioned multiple screw grooves. Attached Figure Description

Reinforcing sound insulation mechanisms 2 are installed on both sides of the solid wood base plate 1. Each reinforcing sound insulation mechanism 2 includes a pair of alloy plates 21 and a pair of solid wood partitions 223. A protective mechanism 3 is installed on the outer edge of each pair of solid wood partitions 223. The alloy plates 21 are symmetrically attached to both sides of the solid wood base plate 1. An anti-deformation mechanism 4 is installed at the outer edge of one of the solid wood partitions 223. Sound insulation components 22 are installed on the outer sides of each of the pair of alloy plates 21. The sound insulation components 22 include EPS boards 221, which are respectively disposed on the outer sides of the two alloy plates 21. Sound insulation felt 222 is glued to the outer sides of each of the two EPS boards 221, and a sound insulation felt 222 is installed on the other side of the sound insulation felt 222. The solid wood partition 223, EPS board 221, and sound insulation felt 222 are glued together, and the EPS board 221 and sound insulation felt 222 are symmetrically distributed along the vertical central axis of the solid wood substrate 1. The alloy board 21 itself has high strength, corrosion resistance, and high toughness. In this device, two alloy boards 21 are respectively placed between a pair of solid wood partitions 223 and solid wood substrate 1, which can greatly increase the overall strength of the wooden door. Secondly, EPS board 221 and sound insulation felt 222 are adjacently placed between the alloy board 21 and the corresponding solid wood partition 223. The EPS board 221 is an expandable polystyrene board, which itself has sound insulation, shock absorption, heat insulation, and moisture-proof effects. Combined with the sound insulation and damping shock absorption effects of the sound insulation felt 222 itself, it can provide good protection for the wooden door.

[0035] The protective mechanism 3 includes melamine paper 31, which is attached to the outside of the solid wood partition 223. The melamine paper 31 and the solid wood partition 223 are glued together, and the dimensions of the melamine paper 31 and the solid wood partition 223 are approximately the same. A waterproof paint layer 32 is coated on the outside of the melamine paper 31, and a protective film 33 is attached to the outside of the waterproof paint layer 32.
