At the same time, when the sound passes through the sound insulation curtain wall panel and the damping telescopic rod, the density of the medium for sound propagation changes, which can consume a part of the sound energy. The sound absorbing cotton layer is made of porous polyester fiber cotton. When the sound wave passes through the sound absorbing cotton layer, the countless channels in the sound absorbing cotton layer will generate friction with the sound wave and heat up, converting the sound energy into heat energy, further consuming the sound wave energy. At the same time, the sound wave is constantly reflected in the sound absorbing cotton layer, which can also consume a large amount of sound wave energy, further improving the sound insulation and sound absorption effect of the device. Through the above structure, the vibration noise of the curtain wall is effectively reduced and the propagation of sound is hindered, which is conducive to improving the shock absorption effect of the device.

[0016] 2. The utility model is provided with a sound insulation curtain wall panel, a damping telescopic rod, a shock absorbing spring, a sound insulation filling layer and a skeleton component.

When an external force squeezes or hits the sound insulation curtain wall panel, the damping telescopic rod and the shock absorbing spring can retract, thereby buffering the impact force and reducing the damage to the sound insulation curtain wall panel or the wall. Through the above structure, when the curtain wall is hit by an external force, the structure can effectively protect the curtain wall and the wall, and reduce the damage to the curtain wall or the wall.

Damping telescopic rods 2 are fixed to both upper and lower ends of one side of the soundproof curtain wall panel 1, and a shock-absorbing spring 3 is arranged outside the damping telescopic rod 2. A mounting member 4 is arranged at one end of the shock-absorbing spring 3, and a mounting bolt 5 is arranged inside the mounting member 4. The mounting bolt 5 is threadedly connected to the damping telescopic rod 2. The mounting member 4 is made of stainless steel, and fixing bolts 6 are fixed to both upper and lower ends of the mounting member 4. The sound-absorbing cotton layer 7 is fixed to one side of the soundproof curtain wall panel 1. The damping telescopic rod 2 and the shock-absorbing spring 3 form a damping elastic connection between the mounting member 4 and the soundproof curtain wall panel 1, thereby reducing the sound insulation of the soundproof curtain wall panel 1 when the sound wave is transmitted to the soundproof curtain wall panel 1. The acoustic vibration phenomenon is avoided to avoid the generation of vibration noise. At the same time, when the sound passes through the sound insulation curtain wall panel 1 and the damping telescopic rod 2, the density of the medium for sound propagation changes, which can consume part of the sound energy. The sound-absorbing cotton layer 7 is made of porous polyester fiber cotton. When the sound wave passes through the sound-absorbing cotton layer 7, the countless channels in the sound-absorbing cotton layer 7 will produce friction with the sound wave and heat up, converting the sound energy into heat energy, further consuming the sound wave energy. At the same time, the sound wave is constantly reflected in the sound-absorbing cotton layer 7, which can also consume a large amount of sound wave energy, further improving the sound insulation and sound absorption effect of the device. Through the above structure, the vibration noise of the curtain wall is effectively reduced and the propagation of sound is hindered, which is beneficial to improving the shock absorption effect of the device.

At the same time, when the sound passes through the soundproof curtain wall panel 1 and the damping telescopic rod 2, the density of the medium for sound propagation changes. , which can consume part of the sound energy. The sound-absorbing cotton layer 7 is made of porous polyester fiber cotton. When the sound wave passes through the sound-absorbing cotton layer 7, the countless holes in the sound-absorbing cotton layer 7 will produce friction with the sound wave and heat up, converting the sound energy into heat energy, further consuming the sound wave energy. At the same time, the sound wave is constantly reflected in the sound-absorbing cotton layer 7, which can also consume a large amount of sound wave energy, further improving the sound insulation and sound absorption effect of the device. The sound insulation curtain wall panel 1 is a hollow plate structure made of aluminum alloy. The metal square tube 901 can be made of galvanized steel or stainless steel. The metal square tube 901 effectively improves the structural strength of the sound insulation curtain wall panel 1.
