Description

Technical Field

[0001] This utility model belongs to the field of window frame technology, and in particular relates to a window frame drainage mechanism. Background Technology

[0002] A window frame is a structural element installed around a door or window opening to support and secure the window sash. It is a crucial component of a window and plays a key role in its performance and aesthetics.

[0003] Window frames typically have drainage outlets on the lower side facing outwards. These outlets are designed to drain rainwater that flows into the window frame during rainy weather. However, in extreme storms, these outlets can backflow, failing to drain internal water and instead allowing more rainwater to enter the window frame. This can then seep into the room through gaps in the window sash. Current technology often uses drain plugs for protection, but these plugs can easily become clogged over time, hindering drainage and impeding effective drainage from the window tracks. Utility Model Content

[0004] This utility model provides a window frame drainage mechanism, which is implemented as follows: A window frame drainage mechanism includes: An outer cover assembled on the outside of the window frame, the outer cover having a collection chamber inside and a drain outlet at the bottom communicating with the outside; The inner shielding component includes a collection chamber with an open structure at one end and a retaining plate located on the outside of the collection chamber. An assembly guide rail is also provided inside the collection chamber. The collection chamber is engaged with the assembly guide rail by the retaining plate. An open receiving interface is provided on the end face of the collection chamber. The collection chamber is covered with the outside of the window drain outlet provided on the window frame through the receiving interface.

[0005] Preferably, the side wall of the collection chamber is provided with a drainage hole, and the water accumulated in the window frame is discharged into the collection chamber from the drain outlet and the receiving interface. The water accumulated in the collection chamber is released into the collection chamber through the drainage hole connected to the collection chamber.

[0006] Preferably, the outer protective cover includes a top plate, a back plate, a lower cutting plate, a base, and an end plate. The top plate, back plate, lower cutting plate, and base are respectively closed at both ends by the end plates to form a semi-open cavity. The base and the top plate are spaced apart to form a port connecting the collection cavity to the outside. The lower cutting plate and the base are also spaced apart to form a drain outlet.

[0007] Preferably, the assembly guide rail is located on the end face of the back plate at the collection chamber.

[0008] Preferably, the number of the card plates is two sets arranged in parallel, and the assembly guide rail is provided with a slot for accommodating the insertion of the card plates.
