Description

Technical Field

[0001] This utility model relates to the field of soundproof doors, and in particular to a polyester fiber soundproof door with high sound absorption. Background Technology

[0002] Doors are very important in architectural decoration. As the demand for doors increases, the demand for sound insulation of doors is also increasing.

[0003] Existing soundproof doors have certain drawbacks in use. First, most common soundproof doors are filled with wood or rock wool, which has poor sound insulation effect. In addition, some door structures have poor sealing, and sound waves can easily leak from the door gaps, affecting the sound insulation effect and reducing the practicality of the soundproof door. To address this, we propose a high sound absorption polyester fiber soundproof door. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a high-sound-absorbing polyester fiber soundproof door. This is achieved by setting a soundproof component consisting of a polyester fiber sound-absorbing layer and a pair of high-density sound-insulating panels. The polyester fiber sound-absorbing layer is composed of honeycomb-shaped polyester fiber panels, which can form multiple slotted structures. This porous structure can dissipate sound wave energy, reduce reflection, and absorb mid-to-high frequency noise. Furthermore, a pair of high-density sound-insulating panels made of inorganic sound-insulating material are installed externally to increase sound insulation and block low-frequency noise transmission. This allows the inner end of the polyester fiber soundproof door to have a strong sound insulation effect. Additionally, a pair of sealing strips are installed inside the soundproof door, working in conjunction with a pair of sealing rings on the outside, effectively reducing leakage from door gaps and improving the sound insulation effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-sound-absorbing polyester fiber soundproof door includes a door frame body, a soundproof door body, and a soundproof component. The inner end of the door frame body is hinged to the soundproof door body, and the soundproof component is installed inside the soundproof door body.

[0007] The sound insulation component includes a polyester fiber sound-absorbing layer, and a high-density sound insulation board is disposed on the outside of the polyester fiber sound-absorbing layer.

[0008] The sound insulation effect of this polyester fiber soundproof door was improved by installing sound insulation components.

[0009] Furthermore, the high-density sound insulation panels are symmetrically distributed and are located at the inner end of the sound insulation assembly.

[0010] By installing high-density sound insulation panels, the door can achieve sound insulation and sound absorption effects, thus improving the effectiveness of the soundproof door.

[0011] Furthermore, sound-absorbing strips are provided at both ends of the inner end of the sound insulation component.

[0012] The sound insulation effect of the sound insulation component was further improved by installing sound-absorbing strip 2.

[0013] Furthermore, the inner end of the second sound-absorbing strip is provided with a sound-absorbing hole, the sound-absorbing holes are evenly distributed, and a sealing strip is provided at the middle of both ends of the second sound-absorbing strip.

[0014] The sealing and sound insulation effect of the sound insulation components can be improved by installing sealing strips.

[0015] Furthermore, a locking block is fixedly connected to the outer end of the sealing strip, and the locking blocks are symmetrically distributed.

[0016] By installing the clips, a pair of clips can form a connection structure at the outer end of the sealing strip, allowing for easy connection between the sealing strip and the positioning frame.

[0017] Furthermore, the outer end of the card block is connected to a positioning frame, which is symmetrically distributed on the outer end of the sealing strip, and the inner end of the positioning frame is provided with a card groove.

[0018] By installing a positioning bracket, which, together with a locking block, can secure the sealing strip to the inner end of the slot, the sealing strip can be easily installed.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting up a sound insulation component, which consists of a polyester fiber sound-absorbing layer and a pair of high-density sound insulation boards, the polyester fiber sound-absorbing layer is composed of honeycomb-shaped polyester fiber boards. This structure can form multiple slot structures. The porous structure can dissipate sound wave energy, reduce reflection, and absorb mid-to-high frequency noise. In addition, a pair of high-density sound insulation boards made of inorganic sound insulation materials are set on the outside to increase the sound insulation and block the transmission of low-frequency noise. This allows the inner end of the polyester fiber soundproof door to have a strong sound insulation effect. Furthermore, a pair of sealing strips are set inside the soundproof door body, which, together with a pair of sealing rings set on the outside of the soundproof door body, effectively reduce leakage from the door gaps and affect the sound insulation effect, thereby improving the sound insulation effect of the polyester fiber soundproof door.

[0021] 2. By setting up sound-absorbing strip 2, the sound-absorbing strip 2 on both sides of the sound insulation component can serve as a transition buffer, reducing the leakage of sound energy at the edge. In addition, multiple sound-absorbing holes are opened at the inner end of the sound-absorbing strip 2, which can expand the absorption frequency band and further improve the sound insulation effect of the sound insulation component.

[0034] The sound insulation component 3 is formed by installing a polyester fiber sound-absorbing layer 31 and a pair of high-density sound insulation boards 32. The polyester fiber sound-absorbing layer 31 is composed of a honeycomb-shaped polyester fiber board. This structure can form multiple slot structures. The porous structure can dissipate sound wave energy, reduce reflection, and absorb mid-to-high frequency noise. In addition, a pair of high-density sound insulation boards 32 made of inorganic sound insulation material are set on the outside to increase the sound insulation and block the transmission of low-frequency noise. This allows the inner end of the polyester fiber soundproof door to have a strong sound insulation effect. The pair of high-density sound insulation boards 32 can form a multiple sound insulation structure on the outside of the polyester fiber sound-absorbing layer 31, allowing the door to achieve sound insulation and sound absorption effects. The sound-absorbing strips 4 set on both sides of the sound insulation component 3 can act as a transition buffer to reduce the leakage of sound energy at the edges. In addition, multiple sound-absorbing holes 5 are opened at the inner end of the sound-absorbing strips 4 to expand the absorption frequency band.

[0037] By installing a pair of clips 7, a connection structure can be formed at the outer end of the sealing strip 6, allowing the sealing strip 6 to be easily connected to the positioning frame 8. The positioning frame 8, together with the clips 7, can snap the sealing strip 6 into the inner end of the slot 9, thus allowing the sealing strip 6 to be easily installed.

[0038] Specific implementation process: When the door is in use, a pair of high-density sound insulation boards 32 can form a multi-layer sound insulation structure on the outside of the polyester fiber sound-absorbing layer 31. The sound insulation component 3 is formed by the polyester fiber sound-absorbing layer 31 and a pair of high-density sound insulation boards 32. The polyester fiber sound-absorbing layer 31 is composed of a honeycomb-shaped polyester fiber board. This structure can form multiple slot structures. The porous structure can dissipate sound wave energy, reduce reflection, and absorb mid-to-high frequency noise. In addition, a pair of high-density sound insulation boards 32 made of inorganic sound insulation material are set on the outside to increase the sound insulation and block the transmission of low-frequency noise, so that the inner end of the polyester fiber soundproof door has a strong sound insulation effect.

[0039] Furthermore, when in use, the sound-absorbing strips 4 on both sides of the sound insulation component 3 can act as a transition buffer, reducing the leakage of sound energy at the edges. In addition, multiple sound-absorbing holes 5 are opened at the inner end of the sound-absorbing strips 4, which can expand the absorption frequency band and improve the sound insulation effect of the door.
