[0026] The multiple reinforcement plates 602 are slidably inserted into the multiple limit grooves 601 of the bottom plate 1 respectively. At this time, the positions of the multiple reinforcement plates 602 will be fixed, and it will be more convenient to weld the reinforcement plates 602. The multiple connecting plates 604 are slidably inserted into the two relatively limit grooves 603 respectively. At this time, the positions of the connecting plates 604 will also be fixed, making the subsequent welding work more convenient. At this time, the entire support assembly 6 will also form an overall frame, thereby ensuring that its overall strength is high enough while also making the sound insulation effect of the device good enough.

[0027] like Figure 2 As shown, a plurality of foam bricks 5 are placed between the two reinforcement plates 602 , and the plurality of foam bricks 5 are distributed between the two reinforcement plates 602 at equal distances.

[0028] It can provide a certain support to the connecting plate 604, further improve the stability of the sound insulation structure, and will not affect the sound insulation effect of the device.

[0030] Place a plurality of glass fiber wool 4 between two foam bricks 5, and finally fill the area around the glass fiber wool 4 with polyurethane foam 3. After solidification, the plurality of foam bricks 5 and the glass fiber wool 4 are bonded into a whole, and the foam pores of the polyurethane foam 3 are closed with a closing rate of 95%, thereby preventing the internal glass fiber wool 4 from getting damp and reducing the sound insulation effect.

After placement, slide and insert multiple connecting plates 604 into the two relatively limiting grooves 2 603 respectively. At this time, the positions of the connecting plates 604 will also be fixed, making the subsequent welding work more convenient. At this time, the entire support assembly 6 will also form an overall frame, thereby ensuring that its overall strength is high enough and the sound insulation effect of the device is good enough.
