[0021] like Figure 1-3 As shown, an environmental noise reduction device of this embodiment includes a mounting frame 10 and a laying frame 20. A rotating shaft 11 is provided on one side of the mounting frame 10. A back plate frame 12 is rotatably connected to the surface of the rotating shaft 11. The back plate frame 12 rotates around the rotating shaft 11. A slot 13 is provided on one side of the mounting frame 10. A spring 14 is fixedly installed inside the slot 13. A pull plate 15 is fixedly installed at one end of the spring 14. When the pull plate 15 is pulled, the pull plate 15 stretches the spring 14. A lock tongue 16 is fixedly installed on one side of the pull plate 15, and the lock tongue 16 is driven to move at the same time. A lock tongue hole 17 is fixedly installed on one side of the back panel frame 12. The lock tongue 16 is plugged into the inside of the lock tongue hole 17, so that the lock tongue 16 is pulled out of the lock tongue hole 17, so that the lock tongue 16 releases the restriction on the back panel frame 12. A support rod 18 is fixedly installed on one side of the mounting frame 10, and a noise reduction plate 19 is clamped between the support rod 18 and the back panel frame 12. After rotating the back panel frame 12, the noise reduction plate 19 is taken out and replaced.

[0022] Example 1: A backplane frame 121 is fixedly installed inside the backplane frame 12, and a support frame 122 is fixedly connected to the middle of the backplane frame 121. The support frame 122 is fixedly installed with the backplane frame 121, and a connecting plate 123 is fixedly installed on one side of the support frame 122. A diagonal support rod 124 is fixedly installed on one side of the connecting plate 123, and then the diagonal support rod 124 is supported on the ground, thereby improving the supporting capacity of the installation frame 10.

[0023] Example 2: A connecting frame 21 is fixedly installed on the bottom of the mounting frame 10, and a threaded hole 22 is provided on one side of the laying frame 20 and the connecting frame 21. A screw 23 is fixedly installed inside the threaded hole 22, and an expansion plate 24 is fixedly connected to the bottom of the laying frame 20. The mounting frame 10 is installed by inserting the connecting frame 21 on the top of the laying frame 20 and then screwing the screw 23 into the threaded hole 22, thereby installing the mounting frame 10 and the laying frame 20.

[0024] Example 3: A slot 25 is provided on the top of the laying frame 20, and the bottom of the noise reduction plate 19 is plugged into the inside of the slot 25. The noise reduction plate 19 is inserted into the inside of the slot 25, and the noise reduction plate 19 is fixed by the slot 25, so that the noise reduction plate 19 can be pre-fixed, avoiding manual and continuous fixing of the noise reduction plate 19.

[0025] Example 4: A docking frame 30 is fixedly installed on the side of the mounting frame 10, and a bolt hole 31 is opened on one side of the docking frame 30. Two sets of mounting frames 10 are placed close to each other so that the docking frames 30 on both sides overlap and the bolt holes 31 coincide, and then the two sets of docking frames 30 are installed by bolts.

[0026] The working principle of this utility model is as follows: when in use,

[0027] 1. Pull the pull plate 15, the pull plate 15 stretches the spring 14, and at the same time drives the lock tongue 16 to move, so that the lock tongue 16 is pulled out of the lock tongue hole 17, so that the lock tongue 16 releases the restriction on the back plate frame 12, and then rotates the back plate frame 12 with the rotation axis 11 as the center, and then takes out the noise reduction plate 19 for replacement. In this device, when the noise reduction plate 19 needs to be replaced, it is only necessary to pull the pull plate 15 to drive the lock tongue 16 to disassemble and replace it, making it more convenient to maintain and replace the noise reduction plate 19.

[0028] 2. Fix the support frame 122 and the back frame 121 together, and then support the diagonal support rods 124 on the ground, thereby improving the supporting capacity of the installation frame 10.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Pull the pull plate 15, the pull plate 15 stretches the spring 14, and at the same time drives the lock tongue 16 to move, so that the lock tongue 16 is pulled out of the lock tongue hole 17, so that the lock tongue 16 releases the restriction on the back plate frame 12, and then rotates the back plate frame 12 around the rotating shaft 11, and then takes out the noise reduction plate 19 for replacement. In this device, when the noise reduction plate 19 needs to be replaced, it is only necessary to pull the pull plate 15 to drive the lock tongue 16 to disassemble and replace it, making the maintenance and replacement of the noise reduction plate 19 more convenient.

[0031] 2. Fix the support frame 122 and the back frame 121 and then support the diagonal support rod 124 on the ground, thereby improving the supporting capacity of the installation frame 10 and the structural strength of the device, which is more convenient to use.
