PD door and window damping buffer structure

Abstract

This invention relates to the field of door and window hardware, specifically disclosing a PD door and window damping buffer structure, including an upper frame hinge rail, an upper frame hanging rail, a hinge sash, and a movable sash. The movable sash has a movable sash hanging rail at its top. The movable sash, through the sliding sash hanging rail and rollers, engages with the upper frame hanging rail and the upper frame hinge rail respectively. The upper frame hinge rail or upper frame hanging rail has a buffer cavity, within which a damping buffer is embedded. The damping buffer has a contact switch. A positioning control block is fixed on the movable sash hanging rail. During the movable sash's engagement with the upper frame hanging rail and upper frame hinge rail, the positioning control block abuts against the contact switch, achieving on / off control of the damping buffer. This invention, by embedding a damping buffer within the upper frame hinge rail and upper frame hanging rail of a narrow PD door and window, in conjunction with the positioning control block at the top of the movable sash, effectively achieves a damping buffer effect when closed. Simultaneously, the overall structure is simplified, does not increase the width of the overall profile, and is aesthetically pleasing and easy to install.
