[0007] Preferably, the connecting cloth piece forms a disassembly structure with the first damping pad via the second Velcro.

[0008] Preferably, the connecting cloth piece forms a rotating structure with the first damping pad by turning the cloth, and the maximum rotation angle of the connecting cloth piece is 180°.

[0009] Preferably, the anti-sticking paper forms a disassembly structure through the second adhesive paper and the shock-absorbing buffer pad, and the top area of ​​the anti-sticking paper is consistent with the bottom area of ​​the second adhesive paper.

[0010] Preferably, the shock-absorbing buffer pad is connected to the second sound insulation layer via a first adhesive tape.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the utility model, two groups of hot-melt damping pads are stacked, and a person separates the connecting cloth pieces on the two groups of hot-melt damping pads from the hot-melt damping pads through the second Velcro, and then rotates the connecting cloth piece on the second damping pad clockwise by turning the cloth over, so that the outer side of the connecting cloth piece is rotated to the second Velcro on the first damping pad, and the first Velcro on the outer side of the connecting cloth piece is adhered to the second Velcro on the first damping pad, thereby fixing the two groups of hot-melt damping pads and facilitating their subsequent transportation.

[0013] 2. In the utility model, when installing the hot-melt damping pad, the anti-sticking paper at the bottom of the shock-absorbing buffer pad can be torn off first. After tearing it off, the second sticking paper at the bottom of the shock-absorbing buffer pad is aligned with the installation position and placed to fix the first damping pad, which is convenient for subsequent installation. The shock-absorbing buffer pad is installed at the bottom of the first damping pad to enhance the shock-absorbing effect of the first damping pad. BRIEF DESCRIPTION OF THE DRAWINGS
