Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a multi-locking point structure for doors and windows. Background Technology

[0002] Doors and windows are opening structures used to connect different spaces in a building. They are an indispensable part of a building, combining functionality and decoration. Their design directly affects the user experience, energy efficiency, safety, and aesthetics of a building. Among them, sliding windows are a type of window that opens and closes by sliding. Their core feature is that the window sash slides horizontally or vertically along the sliding track of the window frame, rather than opening outward or inward like a casement window.

[0003] Sliding windows mainly consist of a window frame, movable window sash, fixed window sash, and sliding rails. The sliding rails are usually installed on the upper and lower edges of the window frame. The movable window sash is equipped with pulleys at the bottom or top. The window is opened or closed by pushing the window sash along the sliding rail. Most sliding windows are horizontal sliding, a few are vertical sliding, but horizontal design is more common. Due to their space-saving characteristics, sliding windows are widely used in areas with high space utilization requirements, such as balconies, kitchens, and bathrooms.

[0004] Existing multi-point locking sliding windows are a type of door and window hardware system that significantly improves sealing, security, and wind pressure resistance by locking simultaneously at multiple contact points between the window sash and the window frame. Its core lies in breaking through the limitations of traditional single-point locking and achieving more balanced force and tighter fit through distributed locking points. However, when two sets of window sashes are fitted together, and there are no vertical beams in the window frame, most sliding windows ensure the sealing between the sliding windows by fitting the window sashes together. If there are gaps between the window sashes, the sealing performance of the sliding window will be reduced. Utility Model Content
