Energy-saving sealing structure for window sash

The utility model provides an energy-saving sealing structure of a window sash, a heat insulation pad is arranged between a connecting piece close to glass and a metal plate, and the heat insulation pad is used for filling and/or separating a cavity at the position of the metal plate. According to the utility model, the cavity between the sash outer frame and the glass and the cavity at the metal plate are effectively filled and separated, so that the loss of heat in conduction and radiation modes at the position is reduced; meanwhile, the heat insulation strips in the cavities between the connecting pieces and the glass fiber reinforced plastic reinforcing ribs and the protruding parts between the sash inner frames also fill and divide the aligned cavities, and the loss of heat in the positions in a conduction and radiation mode is reduced; through the added structure and mutual cooperation, the heat loss of the window sash is reduced, and the heat insulation capacity is improved. 本实用新型提供了一种窗扇节能密封结构，靠近玻璃的连接件
