Recyclable sound insulation unit convenient to disassemble

Abstract

The invention discloses a recyclable sound insulation unit convenient to disassemble. The sound insulation unit comprises a square outer frame and a sound insulation material arranged inside the square outer frame. The upper and lower frames of the square outer frame are provided with connecting structure A and a connecting structure B respectively. The left and right frames of the square outer frame are provided with a connecting structure A and a connecting structure B respectively. The connecting structures A and the connecting structures B on the square outer frame of the sound insulationunit are used for being correspondingly connected with the connecting structures B and the connecting structures A of another sound insulation unit. Each connecting structure A comprises a limiting boss and a rotating locking mechanism, wherein the rotating locking mechanism comprises a rotating arm, a rotating shaft and a locking plate, the limiting boss is of a hollow structure with the open top, the rotating shaft is rotationally arranged between the inner side walls of the limiting bosses, one end of the rotating shaft stretches out of the corresponding limiting boss to be fixedly connected with the rotating arm, and the rotating shaft is sleeved with the corresponding locking plate. Each connecting structure B comprises a limiting groove and a locking groove, wherein the notch of thelocking groove communicates with the groove bottom of the limiting groove, and a locking table is formed at the joint of the locking groove and the limiting groove.

Description

technical field [0001] The invention relates to a sound insulation unit, in particular to a reusable sound insulation unit which is easy to disassemble. Background technique [0002] A soundproof wall or soundproof room is generally made up of multiple soundproof units. Most of the existing sound insulation units are assembled side by side by mortise joints, and then two adjacent sound insulation units are fixed by bolts or glue to increase the strength. Such a structure is inconvenient to disassemble and is not conducive to reuse. [0003] Further, the mortise joint form of the existing sound insulation units is generally through the tenon joint block and the tenon joint groove, and its side is perpendicular to the front of the sound insulation unit, so that after several sound insulation units are spliced ​​together, if a single sound insulation unit The damaged sound insulation unit can only be replaced after the surrounding sound insulation unit is removed. That is, in...
