Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, specifically to a sound-absorbing structure for interior decoration. Background Technology

[0002] Traditional wooden sound-absorbing panels are made of natural wood or artificial boards. By opening holes of different shapes and sizes in the board, sound-absorbing cavities are formed. When sound waves enter, they cause the air inside the holes to vibrate, converting sound energy into heat energy and dissipating it.

[0003] The pore shape parameters of a sound-absorbing panel directly affect the efficiency of sound waves entering the panel, the resonant frequency, and the energy conversion path, thus producing differentiated absorption effects for noise in different frequency bands. In daily use, large-diameter surfaces can absorb mid-to-high frequency noise from televisions and conversations, while micro-diameter surfaces can absorb low-frequency vibration noise from downstairs at night. Traditional sound-absorbing panels have fixed pore sizes on their surfaces, making it impossible to customize them according to usage conditions. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a sound-absorbing structure for interior decoration, including a mounting frame 1. Several sets of mounting blocks 2 are slidably installed inside the mounting frames 1 on both sides of the upper side. A first rotating shaft 3 is rotatably installed on one side of the mounting blocks 2 facing each other. A rotating plate 4 is fixedly welded to the other end of the first rotating shaft 3. A second rotating shaft 5 is rotatably installed on the other side of the rotating plate 4. A sound-absorbing plate 6 is fixedly welded between the other ends of the second rotating shaft 5. Different types of sound-absorbing grooves 18 are opened on the front and back of the sound-absorbing plate 6. The installation between the sound-absorbing plate 6 and the mounting frame 1 is realized by inserting the mounting blocks 2 between the mounting frames 1. By rotating the first rotating shaft 3, the rotating plate 4 can be rotated out. By rotating the second rotating shaft 5, the sound-absorbing plate 6 can be flipped over, thereby changing the type of sound-absorbing grooves 18 on the surface of the sound-absorbing plate 6 according to different noise types.

[0021] Positioning rods 7 are slidably installed inside the lower two sides of the sound-absorbing panel 6. The left positioning rod 7 is slidably connected to the mounting block 2 and the mounting frame 1, and the right positioning rod 7 is slidably installed inside the rotating plate 4, the mounting block 2 and the mounting frame 1. Lifting plates 8 are fixedly welded to the lower part of the positioning rods 7 on both sides. A threaded rod 9 is rotatably connected to the middle of the lifting plate 8. The upper part of the threaded rod 9 is rotatably connected to the lower part of the mounting frame 1. By rotating the threaded rod 9, the lifting plate 8 drives the positioning rod 7 to move upward, so that the positioning rod 7 penetrates the mounting block 2, thereby fixing the mounting block 2. After the sound-absorbing panel 6 is set facing outward, the threaded rod 9 is rotated again, so that the positioning rod 7 penetrates the rotating plate 4 and the lower part of the sound-absorbing panel 6, thereby fixing the rotation of the sound-absorbing panel 6. At the same time, the position of the nut on the threaded rod 9 ensures that the positioning rod 7 does not detach from the mounting frame 1 when moving downward, preventing the lifting plate 8 from rotating arbitrarily.

[0022] A protective shell 11 is fixedly welded to the lower part of the mounting bracket 1 to cover the threaded rod 9 and prevent the threaded rod 9 from being exposed and affecting the appearance. A control door 12 is opened on the front of the protective shell 11, which faces the lower part of the threaded rod 9 for easy control of the threaded rod 9.

[0023] The protective shell 11 has a positioning line 10 inside, which can determine the downward movement distance of the lifting plate 8 based on the position of the positioning line 10, thereby ensuring that the positioning rod 7 just disengages from the rotating plate 4.

[0024] The mounting bracket 1 has a rotating groove 14 on the front side. A third rotating shaft 15 is rotatably mounted inside both sides of the rotating groove 14. A baffle 17 is fixedly welded between the third rotating shafts 15. A torsion spring 16 is fixedly welded between the baffle 17 and the rotating groove 14. The torsion spring 16 is sleeved on the outside of the third rotating shaft 15. The torsion spring 16 pulls the baffle 17 to ensure that the baffle 17 is in the vertical direction, thus blocking the rotating plate 4 and ensuring the overall aesthetics.

[0025] Mounting plates 13 are fixedly welded to the outer sides of the mounting brackets 1 on both sides, so that the mounting brackets 1 are connected to the wall.

[0026] Working principle: In use, the mounting block 2 is inserted between the mounting brackets 1. By rotating the threaded rod 9, the lifting plate 8 drives the positioning rod 7 to move upward, thereby allowing the positioning rod 7 to penetrate the mounting block 2 and fix the mounting block 2, thus realizing the installation between the sound-absorbing panel 6 and the mounting bracket 1. By rotating the first rotating shaft 3, the rotating plate 4 is rotated out. By rotating the second rotating shaft 5, the sound-absorbing panel 6 can be flipped over, thereby changing the type of sound-absorbing groove 18 on the surface of the sound-absorbing panel 6 according to different noise types. Continuing to rotate the threaded rod 9, the positioning rod 7 penetrates the rotating plate 4 and the lower part of the sound-absorbing panel 6, thereby fixing the rotation of the sound-absorbing panel 6.
