Description

Multi-layer composite decorative board structure Technical Field The utility model belongs to the field of plates, and particularly relates to a multi-layer composite decorative plate structure. Background The utility model patent with the bulletin number of CN207405921U and the theme name of a novel multilayer composite aluminum plastic decorative plate, wherein IPC (industrial personal computer) classification number of E04F13/075, the technical scheme of the utility model discloses that a plurality of connecting blocks are connected between plastic base layers, the connecting blocks are fixedly connected through reinforced aluminum strips, a heat insulation layer is arranged between the side plastic base layers of the connecting blocks, an aluminum surface layer is arranged on one side of the plastic base layer far away from the connecting blocks, a plurality of protruding blocks are arranged on one side of the aluminum surface layer, grooves corresponding to the protruding blocks are arranged on the plastic base layer, the protruding blocks are positioned in the grooves, and the aluminum surface layer and the plastic base layer are fixedly bonded through an adhesive. It can be seen that one of the technical solutions of the multi-layer composite decorative plate structure has been disclosed in the above patent. However, the technical solution disclosed in the above patent is focused on fixedly connecting the connection blocks by reinforcing the aluminum strips, so as to achieve a more stable purpose, and the problems of dislocation distribution of the element gaps during lamination, enhancement of the stability and impact resistance of the overall structure and the like are not further solved, and further improvement is needed. Disclosure of utility model The utility model aims at the state of the art, overcomes the defects and provides a multi-layer composite decorative plate structure. The utility model adopts the following technical scheme that the multi-layer composite decorative plate structure comprises a top sheet, a bottom sheet and a decorative plate assembly, wherein: The decorative board assembly is positioned between the top sheet and the bottom sheet and comprises at least two decorative boards; The decorative plates are distributed in a laminated way, two adjacent decorative plates are connected in an adhesive way, the decorative plate is connected with the top piece in an adhesive way, the decorative plate is connected with the bottom plate in an adhesive manner; The decorative board includes the first plate body, the second plate body, third plate body and the fourth plate body that distribute in order and mutually adjoin, and the fourth plate body is equipped with a plurality of mutually adjoin and integrated into one piece's fourth plate body primitive. As a preferable technical scheme of the above technical scheme, the fourth board body element is provided with an element convex portion, an element base portion and two element vertical portions, one end of the element vertical portion is integrally formed with the element convex portion, the other end of the element vertical portion is integrally formed with one end of the element base portion, one end of the element vertical portion is integrally formed with the other end of the element base portion, and the other end of the element vertical portion is integrally formed with the element convex portion of the adjacent fourth board body element. As a preferable technical scheme of the above technical scheme, the hypotenuse length of the element vertical portion of the fourth plate element is sequentially decreased. As a preferable mode of the above technical means, the top sheet is provided with a narrow top sheet portion and a wide top sheet portion fixedly connected to the narrow top sheet portion.
