Description

Technical Field

[0001] This utility model relates to the field of wooden door technology, specifically to a soundproof wooden door based on a multi-layer composite structure. Background Technology

[0002] As people's living standards improve, their requirements for the comfort of their living and working environments are also increasing. The sound insulation performance of interior doors has become an important consideration. However, current wooden doors do not perform well in terms of sound insulation and are unable to effectively block external noise interference, affecting people's quality of life and work. At the same time, some wooden doors also have shortcomings in strength and heat insulation performance. Therefore, we propose a soundproof wooden door based on a multi-layer composite structure. Utility Model Content

[0003] The purpose of this utility model is to provide a soundproof wooden door based on a multi-layer composite structure, which has the advantages of good sound insulation, strength and heat preservation performance. It solves the problem that current wooden doors are not good at sound insulation and cannot effectively block external noise interference, which affects people's quality of life and work. At the same time, some wooden doors also have insufficient strength and heat preservation performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a soundproof wooden door based on a multi-layer composite structure, comprising a door body, with edge banding strips on both the left and right sides of the door body. The door body includes an outer skin layer and a functional layer. The functional layer includes a first high-strength layer, a first sound insulation layer, a heat insulation layer, a second sound insulation layer, and a second high-strength layer. The first high-strength layer is a high-density fiberboard, the first sound insulation layer is sound-absorbing cotton, the heat insulation layer is a polyurethane foam board, the second sound insulation layer is a polyester fiber sound-absorbing board, and the second high-strength layer is plywood. A horizontal groove is formed on the outer skin layer, and a vertical groove is formed on the horizontal groove. A horizontal plate is fixedly connected to the functional layer, and the other end of the horizontal plate is fixedly connected to the vertical plate. The horizontal plate is movably connected to the inner cavity of the horizontal groove, and the vertical plate is slidably connected to the inner cavity of the vertical groove.

[0005] Preferably, the edge banding strip is made of rubber, and the outer skin layer is made of natural solid wood.

[0006] Preferably, the first high-strength layer is located on the front side of the first sound insulation layer, and the first sound insulation layer is located on the front side of the thermal insulation layer.

[0007] Preferably, the thermal insulation layer is located on the front of the second sound insulation layer, and the second sound insulation layer is located on the front of the second high-strength layer.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes two high-strength materials in the first and second high-strength layers to effectively improve the strength of the wooden door body, enabling it to withstand certain external impacts, preventing deformation and damage, and ensuring the structural stability of the wooden door body. The first and second sound insulation layers absorb and block sound waves, reducing the transmission of external noise into the room and improving the sound insulation performance of the wooden door body. The heat insulation layer reduces the transfer of heat between the indoor and outdoor areas, providing heat insulation and helping to maintain a stable indoor temperature and reduce energy consumption.

[0009] 2. This utility model uses edge banding strips to protect the edges of the wooden door body, preventing damage from collisions and scratches. It also prevents moisture from entering the interior of the wooden door body, extending its service life. The outer skin layer enhances the appearance of the wooden door body, giving it the natural texture of wood, while also protecting the internal structure to a certain extent.

The outer skin layer 3 enhances the appearance of the wooden door body 1, giving it the natural texture of wood, while also protecting the internal structure to some extent.

[0018] The working principle of this utility model is as follows: By using two high-strength materials, the first high-strength layer 401 and the second high-strength layer 405, the strength of the wooden door body 1 can be effectively improved, enabling the wooden door body 1 to withstand certain external impacts, making it less prone to deformation and damage, and ensuring the structural stability of the wooden door body 1. The first sound insulation layer 402 and the second sound insulation layer 404 can absorb and block sound waves, reduce the transmission of external noise into the room, and improve the sound insulation performance of the wooden door body 1. The heat insulation layer 403 can reduce the transfer of heat between the indoor and outdoor areas, playing a role in heat insulation and heat preservation, which helps to maintain the stability of the indoor temperature and reduce energy consumption. The edge sealing strip 2 can protect the edges of the wooden door body 1, preventing the edges from being damaged by collisions and scratches, and at the same time preventing moisture from entering the interior of the wooden door body 1, extending the service life of the wooden door body 1.
