Description

Technical Field

[0001] This utility model relates to the field of door technology, specifically to a soundproof door. Background Technology

[0002] In the currently recommended soundproof door design, a 4cm thick steel plate is generally used as the door panel or cement is poured into the door panel to improve the quality and achieve a higher sound insulation effect. However, although the sound insulation effect is achieved, the weight of the door panel will increase the burden on the door hinges. If the hinges cannot fully bear the weight, the door will not be able to open and close easily or even damage the hinges. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a soundproof door that has good sound insulation effect, is lightweight, easy to open and close, and effectively extends its service life.

[0004] Specifically, this utility model discloses a soundproof door, including a door frame and a door panel. The door panel is rotatably connected to the door frame. The door panel has a composite layer structure, consisting of, from the outside to the inside: a panel, a sound insulation and heat insulation pad, a medium-density fiberboard, and a fiber sound-absorbing board. The panel, the sound insulation and heat insulation pad, and the medium-density fiberboard are symmetrically arranged on both sides of the fiber sound-absorbing board. The door panel also includes multiple layers of damping adhesive for connecting the various material layers.

[0005] The advantages of adopting the above technical solution are that by setting the door panel as a composite layer structure, it has good sound insulation performance, is lightweight, and is easy to open and close.

[0006] Furthermore, the fiber sound-absorbing board is a finely spun fiber sound-absorbing board with a thickness between 26 and 30 mm.

[0007] The advantage of adopting the above technical solution is that by setting up finely spun fiber sound-absorbing panels (usually referring to polyester fiber sound-absorbing panels), the sound insulation and sound absorption performance can be improved, while also taking into account environmental protection and decoration functions.

[0008] Furthermore, the thickness of the medium-density fiberboard is between 7 and 10 millimeters.

[0009] The advantages of adopting the above technical solution are that medium-density fiberboard has good resistance to deformation and cracking, which greatly improves the strength of the door. At the same time, the large number of tiny pores inside can effectively absorb sound energy and achieve a good noise reduction effect.

[0010] Furthermore, mounting grooves are provided on both sides and the top of the door panel, and sealing strips are provided in the mounting grooves.

[0011] The advantage of adopting the above technical solution is that the sealing strip plays a role in sealing and sound insulation.

[0012] Furthermore, the door frame includes: a door frame body, two side decorative panels, and an internal filling layer, wherein the internal filling layer includes LVL board and MDF board.

[0013] The advantage of using the above technical solution is that LVL boards and MDF boards have excellent sound insulation and support properties.

[0014] Furthermore, the door frame body has a strip groove, and a sealing strip is installed in the strip groove.

[0015] The advantage of adopting the above technical solution is that the sealing strip on the door frame comes into contact with the door panel, which plays a role in sound insulation.

[0016] Furthermore, the door panel is equipped with a handle and a peephole.

[0017] Furthermore, a dustproof strip groove is provided at the bottom of the door panel, and a soundproof and dustproof strip is installed in the dustproof strip groove.

[0018] The advantage of adopting the above technical solution is that the soundproof and dustproof strips also play the role of soundproofing and dustproofing, ensuring the soundproofing performance of the soundproof door. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] like Figure 1-7 As shown, this utility model discloses a soundproof door, including a door frame 5 and a door panel 6. The door panel 6 is rotatably connected to the door frame 5, specifically by a hinge. The door panel 6 has a composite layer structure, consisting of, from the outside to the inside: a panel 1, a sound insulation and heat insulation pad 2, a medium-density fiberboard 3, and a fiber sound-absorbing board 4. The panel 1, the sound insulation and heat insulation pad 2, and the medium-density fiberboard 3 are symmetrically arranged on both sides of the fiber sound-absorbing board 4. The door panel 6 also includes multiple layers of damping adhesive 7 for connecting the various material layers. The damping adhesive 7 is a high-molecular-weight damping adhesive 7.

[0031] The advantage of adopting the above technical solution is that by setting the door panel 6 as a composite layer structure, it has good sound insulation performance, is lightweight, and is easy to open and close.

[0032] Furthermore, the fiber sound-absorbing panel 4 is a finely spun fiber sound-absorbing panel with a thickness between 26 and 30 mm. It is preferable to use a fiber sound-absorbing panel 4 with a thickness of 28 mm, which is located in the middle of the entire door panel 6 to improve sound insulation and sound absorption performance.

[0033] Furthermore, the two side panels 1 are made of MDF melamine board with a thickness of 2.7 mm, serving a decorative purpose.

[0034] Furthermore, the sound insulation and heat insulation pad 2 can be a 4mm nano high viscoelastic sound insulation and heat insulation pad 2 to ensure its sound insulation effect.

[0035] Furthermore, the thickness of the medium-density fiberboard 3 is between 7-10 mm, and a 9 mm medium-density fiberboard 3 can be used. The medium-density fiberboard 3 has good resistance to deformation and cracking, which greatly improves the strength of the door. At the same time, it has a large number of tiny pores inside, which can effectively absorb sound energy and achieve a good noise reduction effect.

[0036] Furthermore, mounting grooves 61 are provided on both sides and the top of the door panel 6, and sealing strips 62 are provided in the mounting grooves 61.

[0037] Furthermore, the door frame 5 includes: a door frame body 51, two side decorative panels 52, and an internal filling layer. The filling layer includes LVL board 53 and MDF board 54. The LVL board 53 can be 20 mm thick, and the MDF board 54 is 4 mm thick. Both are fixed to the sides of the door frame body 51 using damping adhesive 7. The door frame body 51 also has grooves on both sides for installing the side decorative panels 52, facilitating installation by adhesive or other methods. The LVL board is a multi-layer engineered wood product with high strength and good stability; the MDF board is a medium-density fiberboard.

[0038] Furthermore, the door frame body 51 has a strip groove 55, and a sealing strip is installed in the strip groove 55. When the door is closed, the sealing strip contacts the door panel 6 to achieve a seal.

[0039] In some implementations, door panel 6 is equipped with handle 63 and peephole.

[0040] In some implementation schemes, a dustproof strip groove 64 is provided at the bottom of the door panel 6, and a soundproof and dustproof strip is installed inside the dustproof strip groove 64. The soundproof and dustproof strip also serves the functions of sound insulation and dust prevention, ensuring the sound insulation performance of the soundproof door.

[0041] The entire door panel 6 uses a composite layer structure to achieve multiple layers of sound insulation, ensuring the door's sound insulation effect.

[0042] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
