Abstract
The utility model relates to a door and window hinge which comprises a window frame linkage seat, a window sash linkage seat, a connecting rod, a lock seat, a first limiting piece and a second limiting piece, and the connecting rod is provided with a first lock rod and a second lock rod. The path of the second lock rod is controlled through separation / closing of the second limiting piece, in the separation process, the second lock rod slides into the gap of the limiting piece, and the window sash is hung open around the top / bottom shaft; during closing, the limiting piece forms a blocking structure, the second lock rod is blocked, and the window sash is flatly opened around the side edge shaft. The driving rod and the strip-shaped sliding groove are additionally arranged, the second limiting piece is driven to slide through the lever principle, operation is labor-saving, and the track is accurate. The lower end bolt of the second limiting piece is matched with the strip-shaped inserting hole of the driving rod, and interference is avoided. According to the scheme, a complex multi-connecting-rod system is replaced with the single connecting rod and the double locking rods, the structure is simplified, cost is low, operation is convenient, locking is safe, stability is high, and the requirement for opening and closing doors and windows in multiple scenes is met.
