The invention relates to a pressure plate of an elevator hollow guide rail. The pressure plate comprises a pressure platform, a main plate and a branch block. The pressure plate of the elevator hollow guide rail is formed in a single process by a cold rolled sheet; the wall thickness of the pressure plate is 4mm; the pressure platform is an upwards folded boss, and is perpendicular to the main plate; the height of a folded part of the pressure platform is equal to that of a flange of the hollow guide rail; the branch block is a boss folded in the same direction as that of the pressure platform, and is parallel to the pressure platform; the branch block is higher than the pressure platform and the height of extra part of the branch block is equal to the thickness of the guide rail; the main plate is a plane connecting the pressure platform with the branch block; a through hole is formed in the middle of the main plate; and surface galvanization rust prevention treatment is carried out after the pressure plate is formed integrally. The pressure plate is reasonable in structural design, and is simple and practical; with the adoption of the cold rolled sheet, the pressure plate is easy to form, and low in cost, and can be used repeatedly; and the pressure plate is simple in processing technology, high in efficiency, and easy to popularize and apply, and is suitable for mass production.
