Novel sound absorption panel structure

Abstract

The invention discloses a novel sound absorption panel structure which comprises an outer plate, a first keel support and a second keel support. A sound insulation plate is fixedly connected with theinner wall of the outer plate. An inner layer plate is fixedly connected with the inner wall of the sound insulation plate. A circular groove is formed in the inner wall of the outer plate. A first limiting groove is formed in one side of the inner wall of the inner layer plate. A second limiting groove parallel to the first limiting groove is formed in the other side of the inner wall of the inner layer plate. The first keel support is connected with the second limiting groove through a key groove. The second keel support is connected with the first limiting groove through a key groove. The exterior of the first keel support and the exterior of the second keel support are filled with silencing cotton. The novel sound absorption panel structure is reasonable in structure; the keel structures for long-lasting fixing are installed in the novel sound absorption panel structure; the upwarp and breakage problems of a panel can not appear after long-term use; due to the dual-layer panel design, the product quality can be greatly improved, and the sound absorption effect is better facilitated.

Description

technical field [0001] The invention relates to the technical field of wall materials, in particular to a novel sound-absorbing board structure. Background technique [0002] There are countless sound-absorbing panels on the market. Although most of the sound-absorbing and silent panels can achieve a certain sound-absorbing effect, they all use the structure of cheap sound-absorbing materials, and the structure is unstable. The material structure of most of the composite panels used is , It is prone to problems such as sheet warping after long-term use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a novel sound-absorbing board structure to solve the above-mentioned problems in the background art. [0004] In order to achieve the above purpose, the present invention provides the following technical solutions: a novel sound-absorbing plate structure, comprising an outer plate, a first keel bracket and a second keel bracket, the inner ...
