Description

Technical Field

[0001] This utility model relates to a wooden door, and more particularly to a three-dimensional sound-absorbing and noise-reducing wooden door, belonging to the field of wooden door technology. Background Technology

[0002] Solid wood doors are commonly used in home decoration. They are widely accepted by consumers because of their beautiful and elegant appearance, ease of use, and simple processing. However, due to the special nature of the material, solid wood doors have poor sound insulation. A vibration-damping and noise-reducing wooden door disclosed in application CN202022586736.5 utilizes a door body and an adjusting block. The adjusting block replaces the door body and connects to the hinges. Through the cooperation of the adjusting screw and the mounting groove on the adjusting block, if the adjusting block tilts due to reduced connection precision, the user can adjust the connection position between the door body and the adjusting block using the adjusting screw, thus keeping the door body vertical and avoiding interference with the door frame that could cause noise and vibration problems. The cooperation of the fixing plate and the set screw, along with the mounting groove, locks the adjusting block, preventing loosening between the door body and the adjusting block and improving the installation stability of the door. The separate adjusting block design allows for the use of materials with higher hardness and wear resistance, preventing damage to the connecting parts of the adjusting block from external impacts, effectively avoiding vibration and noise problems during use. However, the aforementioned application has poor sound absorption and noise reduction capabilities for the door body during use, failing to reduce the impact of external noise on the interior.

[0003] In view of the problem that the sound absorption and noise reduction capabilities of the door are poor during use and cannot reduce the impact of external noise on the room, this utility model proposes a new solution. Utility Model Content

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A three-dimensional sound-absorbing and noise-reducing wooden door includes a door frame and a door body that is rotatably connected to the door frame via hinges. The door body includes a frame, a first solid wood door panel is movably installed on the front of the frame, a second solid wood door panel is installed on the back of the frame, and a plurality of interlocking sound-absorbing blocks are movably installed inside the frame.

[0007] Preferably, the two sides of the sound-absorbing block are provided with mutually cooperating protrusions and recesses.

[0008] Preferably, a first through hole is provided at each of the four corners of the front of the frame.

[0009] Preferably, the first solid wood door plate is connected with the frame through a plurality of screws and the first through holes.
