Description

Technical Field

[0001] The utility model belongs to the technical field of wooden doors, in particular to a sound-insulating wooden door. Background Art

[0002] Wooden doors are made primarily of wood or wood-based materials. Due to their natural texture and warm tones, wooden doors are widely used in a variety of settings, including homes and commercial buildings. Depending on the manufacturing process and materials used, wooden doors can be categorized into several types, including solid wood doors, composite doors, and molded doors.

[0003] Soundproof wooden doors are doors specially designed to reduce noise transmission and are usually used in places that require a quiet environment, such as bedrooms, study rooms, conference rooms, and recording studios. At present, there are some soundproof wooden doors on the market. For example, a soundproof wooden door is disclosed on the China Patent Network, and its publication number is CN207177680U. This soundproof wooden door has a good sound insulation effect and is suitable for home use. However, there are some defects and deficiencies that need to be improved: (1) Although some existing soundproof wooden doors can achieve a certain sound insulation effect by adopting sound insulation materials and sound insulation structures, the sound insulation means are relatively simple. When facing high decibels or continuous noise, the sound insulation effect is still not ideal; (2) Some existing soundproof wooden doors prevent sound from being transmitted through the door gap by setting structures such as sealing strips, but the area of ​​the sealing strips is small and it is difficult to fully cover and wrap the edge of the door body, so that there is still a certain gap between the door body and the door frame, thereby affecting the sealing and sound insulation effect; (3) In order to pursue the sound insulation effect, some existing soundproof wooden doors are relatively monotonous in design and lack corresponding decorative structures, making it difficult to coordinate the door body with the style of interior decoration, thereby affecting the aesthetics of the door body. Therefore, in response to the above problems, the soundproof wooden door provided by the utility model is of great significance. Utility Model Content

The soundproof blocks 3 can block the transmission of sound waves to achieve the effect of sound insulation and noise reduction, thereby effectively preventing sound from penetrating the soundproof board 1. The front and rear sides of the soundproof board 1 are respectively installed with a front sound-absorbing board 4 and a rear sound-absorbing board 5. The front sound-absorbing board 4 and the rear sound-absorbing board 5 can be fixed to the soundproof board 1 by adhesive. A layer of sealing gasket 6 is provided at the edge of the soundproof board 1. The sealing gasket 6 can fill the gap between the soundproof wooden door and the door frame to achieve a sealing effect, thereby effectively preventing sound from transmitting through the door gap. The front sound-absorbing board 4 and the rear sound-absorbing board 5 are away from the edge of one side of the soundproof board 1. A retaining ring 7 is provided at the edge, and a number of slots 8 are provided on the side wall surface of the front sound-absorbing panel 4 and the rear sound-absorbing panel 5 close to the sound insulation panel 1. Sound-absorbing cotton 9 is provided in each slot 8. The sound-absorbing cotton 9 has a strong sound-absorbing and noise-reducing effect, which can effectively prevent noise from penetrating the front sound-absorbing panel 4 and the rear sound-absorbing panel 5, thereby improving the sound insulation effect of the soundproof wooden door. A decorative panel 10 is installed on the front sound-absorbing panel 4. A decorative pattern is designed on the decorative panel 10 to enhance the aesthetics and decorativeness of the soundproof wooden door so that the door body can be coordinated with the style of interior decoration. The surface of the decorative panel 10 is coated with a sound-absorbing coating 11. The sound-absorbing coating 11 is made of fiber sound-absorbing paint, which can effectively absorb medium and high-frequency sounds, not only providing excellent sound absorption performance, but also having a certain decorative effect.

[0030] Among them, the sound insulation cavities 2 are equidistantly linearly distributed along the width direction of the sound insulation board 1, and the sound insulation blocks 3 are long strips with a semicircular cross-section. The length of the sound insulation blocks 3 is equal to the height of the sound insulation cavities 2. After the sound passes through the sound insulation board 1 and enters each sound insulation cavity 2, it will contact the surface of the sound insulation blocks 3. At this time, the sound insulation blocks 3 can effectively disperse the sound waves to prevent the sound from continuing to transmit and spread. The multiple sound insulation cavities 2 and multiple sound insulation blocks 3 can expand the contact area and range with the sound waves, thereby effectively improving the sound insulation effect of the sound insulation board 1.

[0031] Among them, the slots 8 are equidistantly distributed linearly along the height directions of the front sound-absorbing panel 4 and the rear sound-absorbing panel 5, respectively. The sound-absorbing cotton 9 and the slots 8 are both rectangular, and the length and width of the sound-absorbing cotton 9 and the slots 8 are correspondingly equal. The sound-absorbing cotton 9 can be fixed by glue or other means. The fixed sound-absorbing cotton 9 can be attached to the inner wall of the slot 8 to play a positioning role. Through multiple sound-absorbing cottons 9, the contact area and range with the sound waves can be expanded, thereby effectively improving the sound absorption effect of the front sound-absorbing panel 4 and the rear sound-absorbing panel 5.

[0032] Among them, the sealing gasket 6 and the retaining ring 7 are both C-shaped, and the width of the sealing gasket 6 is equal to the inner wall spacing between the retaining rings 7. The sealing gasket 6 can be fixed by glue or other means. When the sealing gasket 6 is fixed at the edge of the sound insulation board 1, it can be attached to the side wall of the retaining ring 7. At this time, the sealing gasket 6 can fully cover and wrap the edge of the soundproof wooden door body, thereby ensuring that there is no gap when the door is closed.

[0033] Among them, the length and width of the front sound-absorbing panel 4 and the rear sound-absorbing panel 5 are equal to the length and width of the sound insulation board 1, and the four corners of the front sound-absorbing panel 4 and the rear sound-absorbing panel 5 close to the sound insulation board 1 are fixedly connected with positioning posts 12. A number of positioning grooves 13 are provided on the two side surfaces of the sound insulation board 1. The cross-sections of the positioning grooves 13 and the positioning posts 12 are circular, the number of them is the same, the diameter is equal, and the center of each positioning groove 13 corresponds to the center of each positioning post 12. When the front sound-absorbing panel 4 and the rear sound-absorbing panel 5 are fixed on the sound insulation board 1, each positioning post 12 can be aligned and inserted into the corresponding positioning groove 13. At this time, the mutual cooperation between the positioning posts 12 and the positioning grooves 13 can play a positioning role, so as to improve the stability of the front sound-absorbing panel 4 and the rear sound-absorbing panel 5 after installation, thereby effectively avoiding loosening and displacement between the front sound-absorbing panel 4 and the rear sound-absorbing panel 5 and the sound insulation board 1.

[0034] Among them, four clamping blocks 14 are fixedly connected to the side of the front sound-absorbing panel 4 away from the sound insulation board 1. The clamping blocks 14 are L-shaped and are respectively located at the four corners of the decorative panel 10. The decorative panel 10 is rectangular, and its length and width are respectively equal to the inner wall spacing between the longitudinal clamping blocks 14 and the inner wall spacing between the transverse clamping blocks 14. The four corners of the decorative panel 10 can be respectively fitted on the inner walls of the four clamping blocks 14. At this time, the decorative panel 10 can be positioned by the clamping blocks 14 so that the decorative panel 10 can be fixed on the front sound-absorbing panel 4. The decorative panel 10 can be removed from between the clamping blocks 14 so that the decorative panel 10 with different decorative patterns can be replaced according to the requirements of different decoration styles.
