[0055] A guiding component is arranged inside the first support plate 4. The guiding component is used for guiding and limiting the sliding sleeve block 207.

[0056] In one embodiment, as Figures 2-4 shown, the guiding component includes:

[0057] Two fixing blocks 2011 symmetrically and fixedly connected inside the first support plate 4, the two fixing blocks 2011 are respectively located at the upper and lower ends of one end of the moving push plate 204, and are respectively located at the upper and lower ends of the telescopic rod 2010. Both ends of the two fixing blocks 2011 far from the telescopic rod 2010 are fixedly connected with limiting rods 208, the limiting rods 208 are fixedly connected with the first support plate 4, the sliding sleeve block 207 is sleeved on the outer wall of the limiting rod 208 and is slidably connected with the limiting rod 208. The sliding sleeve block 207 can be slidably guided by the limiting rod 208 to prevent the movement of the sliding sleeve block 207 from deviating;

[0058] A reset assembly is arranged on the outer wall of the limiting rod 208, and the reset assembly is used to push the sliding sleeve block 207 to slide back to its original position;

[0059] In one embodiment, as Figures 2-4 shown, the reset assembly is a spring 209 sleeved on the outer wall of the limiting rod 208. One end of the spring 209 is in contact with the outer wall of the sliding sleeve block 207, and the other end of the spring 209 is in contact with the outer wall of the fixing block 2011. The sliding sleeve block 207 is pushed back to its original position by the spring 209. The positioning pressure plate 202 can be used to squeeze the end face of the sound-absorbing assembly 5 through the mutual cooperation of the support rotating plate 203, the moving push plate 204, the second docking plug board 205, and the first fixing plate 206, so as to install and fix the sound-absorbing assembly 5.

[0060] The above embodiment discloses a modular adjustable sound-absorbing performance wall system. Among them, when in use, the connecting plate 3 is fixed on the wall through bolts, and then the second support plate 6 is fixed on the connecting plate 3 through bolts and is in contact with the outer wall of the first support plate 4. Then the positioning pressure plate 202 is moved above the second docking plug board 205, and then the positioning pressure plate 202 is pushed to sleeve the outer walls of the second docking plug board 205 and the first fixing plate 206 through the docking socket groove. Then the positioning pressure plate 202 is pulled to drive the second docking plug board 205 to move. At this time, the second docking plug board 205 synchronously moves through the first fixing plate 206 driven by the second docking plug board 205. At the same time, the support rotating plate 203 drives the sliding sleeve block 207 to slide along the outer wall of the limiting rod 208 through the rotating shaft driven by the moving push plate 204. During this process, the sliding sleeve block 207 squeezes the spring 209 along the outer wall of the limiting rod 208 to contract, so that the moving push plate 204 can be separated from the outer wall of the first support plate 4;

[0061] After that, place the sound-absorbing component 5 between the two second support plates 6 and make it contact with the outer walls of the first support plate 4 and the connecting plate 3, which can realize the preliminary installation of the sound-absorbing component 5. Then loosen the positioning pressing plate 202. At this time, the spring 209 pushes the sliding sleeve block 207 to slide and reset along the outer wall of the limiting rod 208 through rebound. At the same time, the supporting rotating plate 203 drives the moving push plate 204 to reset synchronously through the rotating shaft under the drive of the sliding sleeve block 207. At this time, the second docking plug board 205 drives the positioning pressing plate 202 to squeeze one end face of the sound-absorbing component 5 through the first fixing plate 206 under the drive of the moving push plate 204, so as to realize the installation and fixation of the sound-absorbing component 5.

[0062] Then repeat the above operation, and the multiple sound-absorbing components 5 can be conveniently installed and fixed by multiple positioning pressing plates 202. After that, move the wall panel 1 above one end of the positioning pressing plate 202 away from the first support plate 4, and make the outer wall of the wall panel 1 fit with the outer wall of the positioning pressing plate 202. Then push the wall panel 1 downward. At this time, the first docking plug board 201 and the second fixing plate 2012 contact the upper surface of the positioning pressing plate 202 through bolts under the drive of the wall panel 1. After that, move the wall panel 1 horizontally until the first docking plug board 201 moves to the port of the positioning sleeve groove on the positioning pressing plate 202. Then, due to its own weight, the wall panel 1 can drive the second fixing plate 2012 and the first docking plug board 201 to insert into the interior of the positioning sleeve groove through bolts until the first docking plug board 201 and the second fixing plate 2012 contact the bottom end of the inner wall of the positioning sleeve groove. At the same time, a rubber gasket 7 located below the wall panel 1 sleeves the outer wall of the bottom end of the wall panel 1, so as to realize the efficient installation and fixation of the wall panel 1.

[0063] When multiple horizontally equidistant wall panels 1 are all installed, at this time, another rubber gasket 7 sleeves the outer walls of the tops of the multiple wall panels 1, which can fill the gaps between the multiple wall panels 1 up and down. Then repeat the above operation, so as to install and fix the sound-absorbing components 5 with corresponding thickness according to the on-site requirements for sound absorption performance.

[0064] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
