Sealing structure for sash window

Abstract

The invention discloses a sealing structure for a sash window. The sealing structure comprises a window sash and a window frame, wherein the window sash is arranged in the window frame; one side face, in perpendicular contact with the window frame, of a frame of the window sash is provided with a groove; the window sash is provided with a protrusion part matched with the groove; a first elastic piece and a second elastic piece, which extend along the perpendicular direction are arranged in the groove; the first elastic piece is arranged on the top surface of the groove and is positioned between contact surfaces of the frame and the window frame; the second elastic piece is arranged on the inner side wall of the groove; after the window sash and the window frame are closed, the second elastic piece is pressed to the outer side wall of the protrusion part. The sealing structure has the beneficial effects that the first elastic piece realizes a basic blocking function to realize a horizontal seal of the window frame and the window sash; the sealing direction of the second elastic piece is perpendicular to the sealing direction of the first elastic piece, so that a longitudinal seal of the window frame and the window sash is realized; the two seals are matched for use to achieve better sealing effect and realize more thorough soundproof, thermal insulating, waterproof and dustproof functions.

Description

technical field [0001] The invention relates to the field of structural design of sliding windows, in particular to the sealing structure of sliding windows. Background technique [0002] The sealing structure of the existing sliding window usually only adopts wool tops, that is, wool tops are installed on the two opposite sides of the window frame to accommodate the sash. After the sash is tightly closed on the window frame, the wool strips contact the frame of the sash. This kind of sealing structure can only play the role of dust prevention, and there is a gap between the window sash and the window frame. When the wind blows, the window sash will shake in the window frame, causing noise and giving people a weak impression. In addition, due to the direct contact between the two sides of the sash and the window frame, once the window is closed with too much force, the sash will have a rigid and violent impact with the window frame, which is easy to damage the overall struct...
