Retractable structure of sliding door and window

Abstract

The invention relates to the technical field of doors and windows, in particular to a retractable structure of a sliding door and window. The retractable structure of the sliding door and window includes a frame body and a sliding door and window; at least two upper retaining sliding blocks are arranged at the upper end of the sliding door and window, and at least two lower retaining sliding blocks are arranged at the bottom end; an upper sliding groove is formed in an upper beam of the frame body, and a lower sliding groove is formed in a bottom beam; all upper retaining sliding blocks extendinto the upper sliding groove, and all lower retaining sliding blocks extend into the lower sliding groove; at least two upper curve retaining sliding sections are arranged in the upper sliding groove; at least two lower curve retaining sliding sections are arranged in the lower sliding groove; and a supporting sliding mechanism slidably supported on the bottom beam is arranged at the bottom endof the sliding door and window; so that the position of the sliding door and window is limited, the sliding door and window is prevented from being pushed away from the frame body due to the recoveryeffect of elastic seals after the elastic seals are installed between the side edges of the sliding door and window and the frame body, and therefore the air tightness between the sliding door and window and the frame body is affected; and the improvement of the air tightness, water tightness, sound insulation and thermal insulation of the sliding door and window is facilitated.
