Composite sealing strip

The utility model relates to the field of rubber sealing structures, in particular to a composite sealing strip, which comprises a mounting body and a sealing body, and is characterized in that the mounting body is U-shaped and is provided with a lateral opening, a U-shaped metal elastic sheet is embedded in the mounting body along the center of the thickness, and one side of the U-shaped part ofthe mounting body is connected with an annular sealing body. According to the composite sealing strip, the U-shaped metal elastic piece is embedded in the installation body and used for being matchedand clamped with the installation portion of a door and window, clamping firmness is improved, and clamping is convenient due to the installation body structure with the U-shaped opening. The annularsealing body structure can be conveniently extruded and deformed to form a contact sealing surface after being propped against a contacted hard piece, so that the sealing reliability is improved. Therefore, according to the com
