NOVELTY - The utility model claims a graphene film, comprising a warming interlayer, fixed board and protective film, the insulating layer is provided with a through hole and a groove, and the groove is provided with a graphite block, the fixing plate is provided with a connection hole; and the connection holes are connected through a bearing and the connection pipe, lower end of the connection pipe is connected with a connecting rod, and the connection lower end of the connecting rod is provided with a limit head, and the connecting rod runs through the interlayer, at the same time, the limiting head is connected with the fixing plate through the limiting hole, the protective film is provided with a groove cover and connection block. The graphene-film can enhance the graphene ground heating strength of the membrane, it is convenient for the interlayer connected with the fixing plate, thereby facilitating the warm forming of film, which can reduce the heating film upper surface area of conductive graphite, so as to avoid the heating film local overheating, at a row circuit failure occurs, it does not affect the use of graphene in other rows, it can make insulating layer and protection film stable connection, avoids using glue connection, to avoid the harmful formaldehyde substance.
