[0032] Please see Figures 1 to 6 This embodiment discloses a sound-absorbing panel fixing device for sound barrier construction, comprising a fixing base plate 1 and a sound-absorbing panel 2. The fixing base plate 1 has a plurality of fixing holes 12 evenly distributed on its surface, facilitating the fixing of the base plate 1 at a designated location. A fixing mechanism is provided between the fixing base plate 1 and the sound-absorbing panel 2. This mechanism includes a connecting column 3 fixedly mounted on the upper surface of the fixing base plate 1. The connecting column 3 has a threaded hole 4 and two limiting cavities 5 inside. Two limiting rods 6, extending to the outside of the connecting column 3, are slidably mounted inside the limiting cavities 5. A limiting ring 11 is fixedly installed inside the limiting cavity 5. The surface of the limiting ring 11 slides in contact with the inner surface of the limiting cavity 5. The limiting ring 11 can prevent the limiting rod 6 from falling out of the limiting cavity 5. A fixing plate 7 is fixedly installed at one end of the limiting rod 6. Fixing pins 8 are fixedly installed on the opposite side surfaces of the two fixing plates 7. A threaded rod 9 that is threaded to the threaded hole 4 is rotatably installed on the surface of the fixing plate 7. Fixing grooves 10 are opened on the opposite side surfaces of the sound-absorbing plate 2. The position of the fixing grooves 10 corresponds to the position of the fixing pins 8. The fixing grooves 10 and the fixing pins 8 are adapted to each other, so that the fixing pins 8 can be inserted into the fixing grooves 10.

[0033] The sound-absorbing panel 2 has a positioning groove 13 at its bottom, and a positioning pin 14 is fixedly installed on the upper surface of the fixed base plate 1. The positioning pin 14 is adapted to the positioning groove 13, which facilitates the insertion of the positioning pin 14 into the positioning groove 13, and facilitates the initial fixation of the position of the sound-absorbing panel 2. The ends of both the fixing pin 8 and the positioning pin 14 are tapered, which facilitates the quick insertion of the fixing pin 8 into the fixing groove 10 and the quick insertion of the positioning pin 14 into the positioning groove 13.

[0034] The surface of the connecting column 3 has a circular hole 15 that communicates with the inside of the limiting cavity 5. The limiting rod 6 is located inside the circular hole 15. The outer surface of the limiting rod 16 slides in contact with the inner surface of the circular hole 15, which facilitates the movement and extension of the limiting rod 6 inside the limiting cavity 5.

[0035] There are multiple fixing pins 8, and the number of fixing grooves 10 is matched with the number of fixing pins 8, which helps to improve the connection stability between the fixing clamp 7 and the sound-absorbing plate 2.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, the fixing hole 12 fixes the fixing base plate 1 in the designated position, and the sound-absorbing plate 2 is placed on the fixing base plate 1 so that the positioning pin 14 is inserted into the positioning groove 13. Then, by rotating the threaded rod 9, the fixing clamp 7 is moved. When the threaded rod 9 is inserted into the threaded hole 4, the fixing clamp 7 approaches the connecting column 3, so that the fixing pin 8 is inserted into the fixing groove 10. At the same time, the fixing clamp 7 can clamp the sound-absorbing plate 2, thereby fixing the sound-absorbing plate 2.
