1. A restraining damping noise reduction plate comprises a connecting plate and a restraining plate, wherein convex-concave structures are respectively arranged on the connecting plate and the restraining plate, the convex-concave structure is continuous convex ridges arranged at intervals on the connecting plate or the restraining plate, the convex-concave structures on the connecting plate and the restraining plate are mutually matched in a staggered way to form a damping chamber, a damping material is arranged in the damping chamber to form a damping layer, it is characterized in that the splicing parts of the connecting plate and the restraint plate are respectively provided with a connecting plate splicing convex edge and a restraint plate splicing convex edge which correspond to each other, the matching sides of the connecting plate splicing convex edge and the restraint plate splicing convex edge are respectively provided with a positioning groove, an elastic isolating strip made of elastic material is also arranged between the connecting plate splicing convex edge and the restraint plate splicing convex edge, the elastic isolating strip is partially embedded in the positioning groove, the connecting plate is connected with the restraint plate through the elastic isolating strip in a splicing and buckling mode, and the elastic isolating strip and the damping layer enable the connecting plate to be elastically isolated from the restraint plate;

  • and an elastic isolation strip which enables the connecting plate and the restraint plate to keep elastic isolation in the convex edge splicing direction of the connecting plate or the convex edge splicing direction of the restraint plate is further arranged between the connecting plate and the restraint plate, and the elastic isolation strip is arranged between the front end of the convex edge splicing direction on the connecting plate and the restraint plate or between the front end of the convex edge splicing direction on the restraint plate and the connecting plate.
