Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

1-3, a plug comprises a main body, wherein the main body comprises a fixing part 1 used for being fixed with a decorative strip and a protruding part 2 arranged on the outer side of the fixing part 1; the fixing part 1 is provided with a channel 11, the fixing part 1 is provided with a screw 3 for fixing the main body on the decorative strip, the main body is placed at a determined position in actual use, the screw 3 penetrates through the fixing part 1 to fix the main body on the decorative strip, the other decorative strip is sleeved outside the main body, and finally the fixing connection of the decorative strip and the decorative strip is completed. The screw 3 comprises a nail head 31 and a nail barrel 32; the boss 2 includes an outer layer 21 and a rubber inner layer 22, and a sound absorbing unit 23 is provided between the outer layer 21 and the rubber inner layer 22. Double glazing used on high floors generally withstands stronger wind than the lower floors and generates more noise, and the decorative strip sandwiched between the double glazing and its connection members impose higher demands on absorbing and attenuating noise, and by providing the sound-absorbing unit 23, and by the cooperation between the sound-absorbing unit 23 and the outer layer 21 and the rubber inner layer 22, the ability to absorb and attenuate noise is improved.

The sound absorbing unit 23 comprises a first sound absorbing opening 231 connected with the outer layer 21, a second sound absorbing opening 232 connected with the rubber inner layer 22, and a hollow air column 233 connected with the first sound absorbing opening 231 and the second sound absorbing opening 232, wherein the hollow air column 233 has the functions of enhancing absorption and weakening noise, the hollow air column 233 also has the functions of vibration prevention and shock resistance, and the upper surface and the lower surface of the circular arc-shaped air column of the hollow air column 233 can effectively decompose the received extrusion force.
