Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a sound-absorbing structure for public spaces in buildings. Background Technology

[0002] In public spaces such as libraries, shopping malls, and conference halls, sound-absorbing structures are key components for optimizing the acoustic environment. With the increase in pedestrian traffic and the normalization of equipment vibration in public spaces, sound-absorbing structures need to withstand external impacts such as personnel collisions and equipment vibrations while maintaining good sealing and sound insulation effects.

[0003] However, traditional sound-absorbing structures mostly use rigid connections for fixing. Rigidly connected sound-absorbing panels are prone to cracking and falling off under external forces. For example, collisions of shopping carts in shopping malls often damage the sound-absorbing panels. Secondly, static sealing methods are difficult to adapt to the slight deformations caused by building settlement and temperature changes. Increased gaps lead to sound wave leakage and reduced sound insulation. At the same time, the repair cost is high and the cycle is long after the structure is damaged. It is difficult to meet the requirements of modern public spaces for acoustic stability and durability. Therefore, there is an urgent need for a sound-absorbing structure for public spaces to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sound-absorbing structure for public spaces in buildings, so as to solve the problem mentioned in the background art that traditional sound-absorbing structures are difficult to buffer when subjected to external force collisions, thus causing the sound-absorbing structure to be easily damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sound-absorbing structure for a building's public space, including a mounting frame, the inner wall of which is provided with a buffer component;

[0006] The buffer assembly includes a sliding frame that is slidably connected to the inner wall of the mounting frame. The side wall of the sliding frame is provided with a sound-absorbing plate. A plurality of first compression springs are fixedly connected to the side wall of the sliding frame. The other end of the plurality of first compression springs is fixedly connected to the same fixing plate. The fixing plate is fixedly connected to the inner wall of the mounting frame.

[0007] Preferably, the top and bottom surfaces of the mounting frame are provided with multiple movable holes, the side wall of the sliding frame is fixedly connected with multiple fixed frames, the inner wall of the fixed frame is slidably connected with a movable frame, the inner walls of two movable frames are rotatably connected with rotating columns, and the surface of the rotating columns is fixedly connected with sound-absorbing rods.

[0008] Preferably, the side wall of the mounting bracket is provided with multiple limiting grooves, and two limiting blocks are fixedly connected to both sides of the sliding bracket, and the limiting blocks are slidably connected to the inner wall of the limiting groove.

[0009] Preferably, a second compression spring is fixedly connected to the bottom surface of the movable frame, and the other end of the second compression spring is fixedly connected to the inner wall of the fixed frame.

[0010] Preferably, the side wall of the sliding frame is provided with an installation groove, and the sound-absorbing plate is fixedly connected to the inner wall of the installation groove.

[0011] Preferably, the size of the movable frame matches that of the movable hole, and the periphery of the movable frame is movably sleeved with the inner wall of the movable hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The buffer components are designed so that when the sound-absorbing panel is pushed by an external force, the mounting groove slides towards the inner wall of the sliding frame under the pressure of the sound-absorbing panel. At the same time, multiple first compression springs in their original state contract and deform, buffering the force on the surface of the sound-absorbing panel and preventing damage when the surface of the sound-absorbing panel comes into rigid contact with the outside. When the external force disappears, the sliding frame moves and drives the sound-absorbing panel to reset. Meanwhile, the second compression spring, the movable frame, and the sound-absorbing rod work together to ensure that the surface of the sound-absorbing rod abuts against the interior ceiling of the building space under the push of the second compression spring, thereby improving the overall sealing and maintaining a good sound insulation effect. Furthermore, when the sliding frame is moved by an external force, the rotating column rotates on the inner wall of the movable frame, so that the surface of the sound-absorbing rod is always in contact with the interior ceiling of the building space, thereby reducing the friction between the surface of the sound-absorbing rod and the interior ceiling of the building space when the mounting groove moves, and improving the service life of the sound-absorbing rod.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a sound-absorbing structure for a public building space, including a mounting frame 1. The inner wall of the mounting frame 1 is provided with a buffer assembly 2. The buffer assembly 2 includes a sliding frame 201, which is slidably connected to the inner wall of the mounting frame 1. The side wall of the sliding frame 201 is provided with a sound-absorbing plate 203. Multiple first compression springs 204 are fixedly connected to the side wall of the sliding frame 201. The other end of the multiple first compression springs 204 is fixedly connected to the same fixed plate 205. The fixed plate 205 is fixedly connected to the inner wall of the mounting frame 1. Through the buffer assembly 2, when the sound-absorbing plate 203 is pushed by an external force, the mounting groove 202 slides towards the inner wall of the sliding frame 201 under the compression of the sound-absorbing plate 203. At the same time, it causes the multiple first compression springs 204 in their original state to contract and deform, thus buffering the force on the surface of the sound-absorbing plate 203 and preventing damage when the surface of the sound-absorbing plate 203 comes into rigid contact with the outside.

[0020] Furthermore, the top and bottom surfaces of the mounting frame 1 are provided with multiple movable holes 206. Multiple fixed frames 207 are fixedly connected to the side wall of the sliding frame 201. Movable frames 208 are slidably connected to the inner wall of the fixed frames 207. Rotating columns 209 are rotatably connected to the inner walls of two movable frames 208. Sound-absorbing rods 210 are fixedly connected to the surface of the rotating columns 209. The sound-absorbing rods 210, movable frames 208 and rotating columns 209 work together so that when the sliding frame 201 is moved by external force, the rotating columns 209 rotate on the inner wall of the movable frames 208. This reduces the friction between the surface of the sound-absorbing rods 210 and the ceiling of the building space when the mounting groove 202 moves, and improves the service life of the sound-absorbing rods 210.

[0021] Furthermore, the side wall of the mounting frame 1 is provided with multiple limiting grooves 212, and two limiting blocks 213 are fixedly connected to both sides of the sliding frame 201. The limiting blocks 213 are slidably connected to the inner wall of the limiting grooves 212. The limiting grooves 212 and the limiting blocks 213 cooperate with each other to facilitate the limiting of the sliding frame 201 and facilitate the parallel movement of the sliding frame 201.

[0022] Furthermore, a second compression spring 211 is fixedly connected to the bottom surface of the movable frame 208, and the other end of the second compression spring 211 is fixedly connected to the inner wall of the fixed frame 207. Through the second compression spring 211, the surface of the sound-absorbing rod 210 abuts against the inner ceiling of the building space under the push of the second compression spring 211, thereby improving the overall sealing and maintaining a good sound insulation effect.

[0023] Furthermore, the side wall of the sliding frame 201 is provided with an installation groove 202, and the sound-absorbing plate 203 is fixedly connected to the inner wall of the installation groove 202. The installation groove 202 facilitates the embedding of the sound-absorbing plate 203 into the interior of the sliding frame 201, thereby improving the overall smoothness.

[0024] Furthermore, the dimensions of the movable frame 208 and the movable hole 206 are matched, and the periphery of the movable frame 208 is movably sleeved with the inner wall of the movable hole 206. The movable hole 206 facilitates the limitation of the movable frame 208, thereby limiting the sliding frame 201.

[0025] Working principle: During use, the buffer component 2 ensures that when the sound-absorbing plate 203 is pushed by an external force, the mounting groove 202 slides towards the inner wall of the sliding frame 201 under the pressure of the sound-absorbing plate 203. At the same time, it causes multiple first compression springs 204 in their original state to contract and deform, thus buffering the force on the surface of the sound-absorbing plate 203 and preventing damage when the surface of the sound-absorbing plate 203 comes into rigid contact with the outside. When the external force disappears, the multiple first compression springs 204 extend and push the sliding frame 201 to move. The movement of the sliding frame 201 causes the sound-absorbing plate 203 to reset.

[0026] Meanwhile, the second compression spring 211, the movable frame 208, and the sound-absorbing rod 210 work together to ensure that the surface of the sound-absorbing rod 210 abuts against the interior ceiling of the building space under the push of the second compression spring 211, thereby improving the overall sealing and maintaining a good sound insulation effect.

[0027] Secondly, when the sliding frame 201 is moved by an external force, the rotating column 209 rotates on the inner wall of the movable frame 208, so that the surface of the sound-absorbing rod 210 is always in contact with the interior ceiling of the building space, thereby reducing the friction between the surface of the sound-absorbing rod 210 and the interior ceiling of the building space when the mounting groove 202 moves, and improving the service life of the sound-absorbing rod 210.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
