Description

Technical Field

[0001] This utility model relates to the field of sound absorption, specifically a sound-absorbing microporous decorative round tube. Background Technology

[0002] Sound-absorbing mechanisms play a vital role in large public spaces, effectively reducing noise reflection and reverberation time, thereby improving the acoustic environment quality of the space, enhancing speech clarity, avoiding noise interference, and providing people with a more comfortable environment for communication and activities.

[0003] In the existing technology, traditional sound absorption mechanisms are mainly composed of porous materials, such as foam and fiber fabrics, and frame structures. The porous materials convert sound waves into heat energy for absorption, while the frame is used to fix and support these materials, thereby achieving the sound absorption effect.

[0004] However, traditional sound-absorbing mechanisms, due to their reliance on the physical properties of organic materials, are prone to deformation or aging under high temperatures and compression under high pressure, leading to a decline in sound absorption performance. Furthermore, foam materials are sensitive to moisture, and prolonged exposure to humid environments reduces their lifespan. Consequently, the overall structure performs poorly in terms of temperature resistance, pressure resistance, and moisture resistance, making it difficult to meet the long-term use requirements of harsh environments and resulting in a lack of durability. To address these issues, this invention proposes a sound-absorbing microporous decorative circular tube to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a sound-absorbing microporous decorative round tube to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sound-absorbing microporous decorative round tube with a hole diameter of 0.2-0.5mm and a plate thickness of 0.5-1.5mm. The sound-absorbing microporous decorative round tube includes: a mounting screw, which is installed in a plurality of units at both ends of a fixed top plate surface, and a connecting frame is installed at the lower end of the mounting screw.

[0007] The snap-fit ​​keel has a connecting screw fixedly installed on its upper surface. One end of the snap-fit ​​keel has an L-shaped hole, and the bottom surface of the snap-fit ​​keel has several slots into which a sound-absorbing round tube is inserted.

[0008] Preferably, the mounting screws are installed in a plurality of units below the fixed top plate, and a fixing screw tube is screwed onto the mounting screw. The fixing screw tube is installed in a plurality of linear equidistant array symmetrical structures at both ends of the fixed top plate surface. A first fixing block is fixedly installed at the end of the mounting screw near the fixing screw tube, and a first anti-slip plate is inserted between the first fixing block and the fixing screw tube.

[0009] Preferably, the connecting frame is a rectangular parallelepiped structure, with connecting holes on both the upper and lower surfaces. A mounting screw passes through the connecting hole at the end away from the fixing screw tube. A second fixing block is fixedly installed at the end of the mounting screw away from the fixing screw tube. A first mounting nut is screwed onto the lower end of the mounting screw, and a second anti-slip plate is engaged between the first mounting nut and the connecting frame.

[0010] Preferably, the connecting screw is fixedly installed on both ends of the buckle keel, one end of the connecting screw passes through the connecting hole opened on the lower end surface of the connecting frame, and a second mounting nut is screwed onto the upper end of the connecting screw.

[0011] Preferably, the snap-fit ​​keel has a rectangular parallelepiped structure, and multiple snap-fit ​​keels are fixedly installed at the lower end of the connecting frame. One end of the snap-fit ​​keel has several L-shaped holes arranged linearly and equidistantly, with one end of the L-shaped holes located on the bottom surface of the snap-fit ​​keel. The bottom surface of the snap-fit ​​keel has several slots arranged linearly and equidistantly, and the outermost end of the snap-fit ​​keel has several mounting screw holes arranged linearly and equidistantly.

[0012] Preferably, the sound-absorbing round tubes are installed in multiple units on the lower surface of the snap-fit ​​keel. A limiting groove is formed on the upper surface of the snap-fit ​​keel, and several linearly equidistant sound-absorbing holes are formed on the surface of the limiting groove. The sound-absorbing holes fit into the L-shaped fine holes on the bottom surface of the snap-fit ​​keel. A locking block is fixedly installed on the side wall of the limiting groove, and the locking block can be locked into the locking groove. A mounting plate is fixedly installed on the end of the sound-absorbing round tube near the mounting screw hole. Several holes are formed on the surface of the mounting plate, and threaded rods are set in the holes. The threaded rods are screwed to the outside of the mounting screw holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The sound-absorbing microporous decorative round tube proposed in this utility model is used by installing one end of the mounting screw on the surface of the fixed top plate and fixing the connecting frame on the other end of the mounting screw. Then, the snap-fit ​​keel is installed on the lower end of the connecting frame through the connecting screw, and the sound-absorbing round tube is snapped into the slot and fixed.

The hole diameter is 0.2-0.5mm and the plate thickness is 0.5-1.5mm, which can achieve quick installation. The sound wave in the inner cavity will resonate with the internal air molecules, so that the sound wave energy is gradually consumed. After the sound wave energy is consumed in the inner cavity, it will not be repeatedly reflected in the space, forming a long-term reverberation. Thus, it achieves better sound absorption effect and is more durable, thus avoiding the problem of the sound absorption mechanism being not durable. Attached Figure Description

[0023] The snap-fit ​​keel 3 has a connecting screw 4 fixedly installed on its upper surface. One end of the snap-fit ​​keel 3 has an L-shaped fine hole 7. The bottom surface of the snap-fit ​​keel 3 has several slots 5. A sound-absorbing round tube 6 is inserted into the slots 5.

[0024] In use, one end of the mounting screw 1 is installed on the surface of the fixed top plate, and the connecting frame 2 is fixedly installed on the other end of the mounting screw 1. Then, the snap-fit ​​keel 3 is installed on the lower end of the connecting frame 2 through the connecting screw 4, and the sound-absorbing round tube 6 is snapped into the slot 5 and fixed. When sound propagates in the air, the sound wave will pass through the L-shaped fine hole 7. When the sound wave passes through the L-shaped fine hole 7, the sound wave will enter the inner cavity of the sound-absorbing round tube 6. The hole diameter is 0.2-0.5mm and the plate thickness is 0.5-1.5mm, which can achieve quick installation. The sound wave in the inner cavity will resonate with the internal air molecules, so that the sound wave energy is gradually consumed. After the sound wave energy is consumed in the inner cavity, it will not be repeatedly reflected in the space, forming a long-term reverberation, thus achieving better sound absorption effect and greater durability, thus avoiding the problem of the sound absorption mechanism being not durable.

[0025] Example 2: Based on Example 1, a sound-absorbing circular tube 6 is provided for better sound absorption. Multiple sound-absorbing circular tubes 6 are installed on the lower surface of the snap-fit ​​keel 3. A limiting groove 15 is formed on the upper surface of the snap-fit ​​keel 3, and several linearly equidistant sound-absorbing holes 16 are formed on the surface of the limiting groove 15. The sound-absorbing holes 16 fit into the L-shaped fine holes 7 on the bottom surface of the snap-fit ​​keel 3. A locking block 17 is fixedly installed on the side wall of the limiting groove 15, and the locking block 17 can be inserted into the locking slot 5. A mounting plate 14 is fixedly installed on the end of the sound-absorbing circular tube 6 near the mounting screw hole 13. Several holes are formed on the surface of the mounting plate 14, and threaded rods are provided in the holes. The threaded rods are screwed to the mounting screw holes 13. The snap-fit ​​keel 3 has a rectangular structure, and multiple snap-fit ​​keels 3 are fixedly installed on the connecting frame 2. At the lower end, the surface of one end of the snap-fit ​​keel 3 is provided with several linearly equidistant L-shaped fine holes 7. One end of the L-shaped fine holes 7 is located on the bottom surface of the snap-fit ​​keel 3. The bottom surface of the snap-fit ​​keel 3 is provided with several linearly equidistant slots 5. The outermost end of the snap-fit ​​keel 3 is provided with several linearly equidistant mounting screw holes 13. When sound propagates in the air, the sound waves will enter the L-shaped fine holes 7 in the snap-fit ​​keel 3 and enter the sound-absorbing round tube 6 through the L-shaped fine holes 7. When the sound waves enter the sound-absorbing round tube 6, the sound waves will resonate with the air molecules in the sound-absorbing round tube 6. During the resonance process, the energy of the sound waves will be continuously consumed. After the energy of the sound waves is consumed, they will not be repeatedly reflected in the space, thus forming a long reverberation, thereby achieving a better sound absorption effect.

[0026] Example 3: Based on Example 2, to improve the overall aesthetics and durability, mounting screws 1 are provided. Multiple mounting screws 1 are installed below the fixed top plate. A fixing screw tube 8 is screwed onto the mounting screw 1. Multiple fixing screw tubes 8 are arranged in a linear, equidistant, symmetrical array at both ends of the fixed top plate surface. A first fixing block is fixedly installed at the end of the mounting screw 1 closest to the fixing screw tube 8. A first anti-slip plate 10 is inserted between the first fixing block and the fixing screw tube 8. The connecting frame 2 has a rectangular structure. Connecting holes are provided on both the upper and lower surfaces of the connecting frame 2. The end of the mounting screw 1 furthest from the fixing screw tube 8 passes through the connecting holes. A second fixing block is fixedly installed, and a first mounting nut 9 is screwed onto the lower end of the mounting screw 1. A second anti-slip plate 11 is inserted between the first mounting nut 9 and the connecting frame 2. The connecting screw 4 is fixedly installed on both ends of the buckle keel 3. One end of the connecting screw 4 passes through the connecting hole opened on the lower end surface of the connecting frame 2, and a second mounting nut 12 is screwed onto the upper end of the connecting screw 4. During installation, the buckle keel 3 is installed on the lower end of the connecting frame 2 through the connecting screw 4. The buckle keel 3 is arranged in a linear array, making the overall structure more beautiful. The whole is made of fireproof, moisture-proof and corrosion-resistant materials, which makes the whole more durable, thus achieving both greater durability and better installation.

[0027] In actual use, one end of the mounting screw 1 is installed on the surface of the fixed top plate, and the connecting frame 2 is fixedly installed on the other end of the mounting screw 1. Then, the snap-fit ​​keel 3 is installed on the lower end of the connecting frame 2 through the connecting screw 4, and the sound-absorbing round tube 6 is snapped into the slot 5 and fixed. When sound propagates in the air, the sound wave will pass through the L-shaped fine hole 7. When the sound wave passes through the L-shaped fine hole 7, the sound wave will enter the inner cavity of the sound-absorbing round tube 6. The hole diameter is 0.2-0.5mm and the plate thickness is 0.5-1.5mm, which can achieve quick installation. The sound wave in the inner cavity will resonate with the internal air molecules, so that the sound wave energy is gradually consumed. After the sound wave energy is consumed in the inner cavity, it will not be repeatedly reflected in the space, forming a long-term reverberation, thus achieving better sound absorption effect and greater durability, thus avoiding the problem of the sound absorption mechanism being not durable.
