Description

Technical Field

[0001] This utility model relates to the field of wooden door technology, specifically to a damping noise reduction wooden door. Background Technology

[0002] Wooden doors, also known as doors made of wood, can be categorized into many types based on their material, craftsmanship, and purpose. They are widely used in residential and commercial buildings, and come in various styles, including European retro, minimalist modern, American, Mediterranean, Chinese, French romantic, and Italian. The process of manufacturing wooden doors involves first shaping the door frame, then fixing the internal support beams into the frame, and finally installing the wooden door panels onto the door frame.

[0003] Chinese patent CN213869593U discloses a noise-reducing wooden door that reduces the volume transmitted on both sides of the door by setting a noise-reducing layer. The noise-reducing layer of this utility model achieves a seamless connection between the front and back of the noise-reducing layer by setting a quadrangular prism and a noise-reducing supplement. In addition, the reflective hole adopts a conical structure, which better realizes the sound reflection effect and better hinders the transmission of sound, resulting in good noise reduction effect.

[0004] In the above solution, a noise reduction layer is formed by using a noise reduction prism and a noise reduction supplement to achieve effective noise reduction and sound insulation. However, relying solely on the noise reduction layer to support the interior of the door frame will result in relatively weak structural strength and poor impact resistance of the entire wooden door, making it very easy to damage the door panel when subjected to external force.

[0005] Therefore, this utility model provides a damping noise reduction wooden door to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a damping noise reduction wooden door to solve the problem that relying solely on the noise reduction layer to support the inside of the door frame will result in relatively weak structural strength and poor impact resistance of the entire wooden door, making it easy to damage the door panel when subjected to external force collisions.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A damping noise reduction wooden door includes a carbon crystal plate and a door frame. The carbon crystal plate is wrapped around the outer surface of the door frame, and elastic elements for elastic protection are provided on both sides of the carbon crystal plate.

[0009] The door frame is equipped with a first rubber sound insulation board and a second rubber sound insulation board. A solid wood board is also provided inside the door frame, and the solid wood board is located between the first rubber sound insulation board and the second rubber sound insulation board. Sound-absorbing components are provided on both sides of the solid wood board.

[0010] Preferably, the elastic element includes a leather wrapping surface and a cushioning pad, one side of the cushioning pad is bonded to the carbon crystal plate, the leather wrapping surface is fixed to the carbon crystal plate by a needle, and the cushioning pad is located inside the leather wrapping surface.

[0011] Preferably, both the leather wrapping surface and the cushioning pad are provided with fitting grooves.

[0012] Preferably, the solid wood board component comprises solid wood strips arranged at equal intervals, and adjacent solid wood strips are bonded together with glue.

[0013] Preferably, the sound-absorbing component includes first positioning blocks that are fixedly connected to the door frame and arranged at equal intervals, and the solid wood strip has a first positioning groove that matches the first positioning block, and a first sound-absorbing cotton is provided between adjacent first positioning blocks.

[0014] Preferably, the sound-absorbing component further includes a second positioning block fixedly connected to the door frame and arranged at equal intervals, a second positioning groove matching the second positioning block is provided on the solid wood strip, and a second sound-absorbing cotton is provided between adjacent second positioning blocks.

[0015] Preferably, the first positioning groove and the second positioning groove are arranged alternately on the solid wood strip, and the first sound-absorbing cotton and the second sound-absorbing cotton both cover the overlapping surface of the adjacent solid wood strip.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By setting solid wood panels composed of equally spaced solid wood strips inside the door frame, and gluing adjacent solid wood strips together, the overall structural strength of the door frame and carbon crystal board can be effectively enhanced. The elastic elements set on both sides of the carbon crystal board can form an elastic protective layer to prevent external impact from acting directly on the carbon crystal board, significantly improving the impact resistance of the wooden door and reducing damage to the door panel from external collisions.

[0018] 2. The first and second rubber sound insulation boards installed inside the door frame form a two-layer rubber sound insulation structure, which can effectively block sound transmission. In addition, multiple first and second sound-absorbing cottons in the sound-absorbing components on both sides of the solid wood board form sound-absorbing layers and cover the overlapping surfaces of adjacent solid wood strips, which can further absorb noise. Furthermore, the sponge cushioning pad can also play a certain role in sound insulation. Through the synergy of multiple sound insulation and sound absorption structures, the noise reduction effect of the wooden door is greatly improved. Attached Figure Description

One side of the buffer pad 4 is bonded to the carbon crystal plate 1, the leather-wrapped surface 2 is fixed to the carbon crystal plate 1 by a gun needle, and the buffer pad 4 is located inside the leather-wrapped surface 2.

[0028] The cushioning pad 4 is wrapped and protected by the leather wrapping surface 2. The elastic element formed by the cushioning pad 4 and the leather wrapping surface 2 can form an elastic protective layer on both sides of the carbon crystal plate 1, preventing external impact from directly hitting the carbon crystal plate 1. In addition, the sponge material cushioning pad 4 can also play a certain role in sound insulation.

[0029] Both the leather-covered surface 2 and the cushioning pad 4 are provided with adapter grooves 3. The door lock structure will be installed in the adapter grooves 3. The adapter grooves 3 are used to avoid the leather-covered surface 2 and the cushioning pad 4 from obstructing the door lock structure.

[0034] The stability of the solid wood strip 8 within the door frame 5 is improved by the cooperation of the first positioning block 9 and the first positioning groove 11, while the sound-absorbing layer formed by multiple first sound-absorbing cottons 13 further blocks noise.

[0035] The sound-absorbing component also includes a second positioning block 10 that is fixedly connected to the door frame 5 and arranged at equal intervals. A second positioning groove 12 that matches the second positioning block 10 is opened on the solid wood strip 8, and a second sound-absorbing cotton 14 is provided between adjacent second positioning blocks 10.

[0036] The stability of the solid wood strip 8 within the door frame 5 is enhanced by the cooperation of the second positioning block 10 and the second positioning groove 12, while the sound-absorbing layer formed by multiple second sound-absorbing cotton 14 further blocks noise.

[0037] The first positioning groove 11 and the second positioning groove 12 are arranged alternately on the solid wood strip 8, and the first sound-absorbing cotton 13 and the second sound-absorbing cotton 14 both cover the overlapping surface of the adjacent solid wood strip 8.

[0038] The noise reduction effect of the door is improved by forming two sound-absorbing layers on both sides of the solid wood strip 8 using the first sound-absorbing cotton 13 and the second sound-absorbing cotton 14.
