A self-absorption type environmental-protection sound-absorption decorating plate comprises a hollow
pipe, a hollow
elbow bend, a hollow connector, an evenness regulating nut and a
metal jump ring, wherein the hollow
elbow bend and the hollow connector are provided with a movable regulation hole and a socket port, the evenness regulating nut is provided with a nut and a double-screw bolt, a
brute force magnet is imbedded in the nut, and the
metal jump ring is provided with a
metal spring ring and a metal
spring steel wire. The spring ring of the metal jump ring is sleeved in the evenness regulating nut to enable the evenness regulating nut to have a self-absorption type buckle function, an evenness regulating function and a
magnet absorption function, then the evenness regulating nut is connected with the hollow
elbow bend and the hollow connector to form a multifunctional right-angle connection
system and a multifunctional bending connection
system, the multifunctional right-angle connection
system and the multifunctional bending connection system are respectively connected with the hollow
pipe to form a frame, sound-absorption materials are filled in the frame, decorating fabrics are wrapped on the surface of the frame, and the self-absorption type environmental-protection sound-absorption decorating plate with the self-absorption type buckle function, evenness regulating function, the
magnet absorption function and translation adjustment function towards each direction is finally formed.
