Description

Technical fields:

[0001] This utility model relates to the field of aluminum-clad wood window technology, and in particular to a drainage device for the bottom frame of an aluminum-clad wood window. Background technology:

[0002] Aluminum-clad wood windows are frames made by mechanically combining aluminum alloy profiles and solid wood while retaining the characteristics and functions of pure solid wood windows. Ordinary doors and windows rely mainly on sealing strips for sealing and waterproofing. However, after prolonged use and repeated exposure to external conditions such as freeze-thaw cycles and thermal expansion and contraction, the sealing strips will age and deform, causing water and air leaks. Leaking sealant allows rainwater to seep into the aluminum-clad wood window. If not drained promptly, this will affect the lifespan of the door and window. Therefore, existing technologies typically include drainage holes at the bottom of aluminum-clad wood windows. While this structure allows for timely drainage, it also suffers from air leakage and poor insulation performance in cold seasons. This invention designs a drainage structure for aluminum-clad wood windows that combines effective drainage with good insulation performance. Utility Model Content:

[0003] The purpose of this utility model is to provide a drainage device for the lower frame of an aluminum-clad wood window to solve the technical problems of air leakage and poor thermal insulation performance in the drainage structure of existing aluminum-clad wood windows.

[0004] The present invention relates to a drainage device for the bottom frame of an aluminum-clad wood window, comprising a wooden frame and an aluminum outer frame, the wooden frame and the aluminum outer frame being connected by locking components. A support plate is installed between the wooden frame and the aluminum outer frame, and glass is installed on the support plate. The glass is sealed to the wooden frame and the aluminum outer frame with sealant. A first drainage hole is provided on the support plate. A labyrinth drainage assembly is installed in the connection gap between the wooden frame and the aluminum outer frame. A trigger-type drainage assembly is provided at the bottom end of the aluminum outer frame, and the trigger-type drainage assembly is located directly below the labyrinth drainage assembly.

[0005] Furthermore, the labyrinth drainage assembly includes a sealing gasket, within which a labyrinth flow hole is provided, the flow path of which is a multi-step zigzag shape.

[0006] Furthermore, the trigger-type drainage assembly includes a three-tiered stepped through-hole formed at the bottom of the aluminum outer frame, a movable column slidably inserted into the three-tiered stepped through-hole, a limiting platform connected to the top of the movable column, the limiting platform being located within the connection gap between the wooden frame and the aluminum outer frame, a trigger plate connected to the bottom of the movable column, the trigger plate being slidably connected to the three-tiered stepped through-hole, the trigger plate extending outside the three-tiered stepped through-hole, an inclined hole obliquely formed on the aluminum outer frame, the inclined hole communicating with the three-tiered stepped through-hole, a second drainage through-hole vertically formed on the trigger plate, and a compression spring fitted on the movable column, the compression spring being used to apply a downward elastic force to the trigger plate.

[0007] Furthermore, a sealing ring is installed at the top of the trigger plate, which is used to seal the three-step through hole.

[0008] Furthermore, the bottom of the trigger plate is arc-shaped or wedge-shaped.

[0009] Furthermore, the three-step through hole and the movable column are in clearance fit.

[0010] The beneficial effects of this utility model are as follows: This utility model designs a trigger-type drainage component in the aluminum frame of the aluminum-clad wood window. This allows the trigger-type drainage component to open smoothly when the window is opened after rain, preventing rainwater from accumulating inside the door and window and improving the service life of the door and window. When the window is closed, the trigger-type drainage component closes to ensure that the door and window does not leak air and improves the thermal insulation performance of the door and window. It is worth promoting and using on a large scale. Attached image description:

[0013] In the diagram, 1 is the wooden frame, 2 is the aluminum outer frame, 3 is the sealant, 4 is the support plate, 5 is the first drainage hole, 6 is the sealing gasket, 7 is the labyrinth flow hole, 8 is the locking element, 9 is the compression spring, 10 is the moving column, 11 is the oblique hole, 12 is the trigger plate, 13 is the second drainage hole, 14 is the limiting platform, 15 is the sealing ring, 16 is the glass, and 17 is the three-step through hole. Detailed implementation method:

[0014] like Figure 1As shown, a bottom frame drainage device for an aluminum-clad wood window includes a wooden frame 1 and an aluminum outer frame 2, which are connected by a locking member 8. A support plate 4 is installed between the wooden frame 1 and the aluminum outer frame 2, and a glass 16 is installed on the support plate 4. The glass 16 is sealed to the wooden frame 1 and the aluminum outer frame 2 by a sealant 3. A first drainage hole 5 is provided on the support plate 4. A labyrinth drainage assembly is installed in the connection gap between the wooden frame 1 and the aluminum outer frame 2. A trigger-type drainage assembly is provided at the bottom of the aluminum outer frame 2, and the trigger-type drainage assembly is located directly below the labyrinth drainage assembly. The labyrinth drainage assembly includes a sealing gasket 6, and a labyrinth flow hole 7 is provided in the sealing gasket 6. The flow path of the labyrinth flow hole 7 is a multi-step zigzag shape. The multi-step zigzag shape of the labyrinth flow hole 7 can better prevent cold air backflow and improve the thermal insulation performance of the door and window.

[0015] like Figure 1 and Figure 2 As shown, the trigger-type drainage assembly includes a three-tiered stepped through-hole 17 formed at the bottom of the aluminum outer frame 2. A movable column 10 is slidably inserted into the three-tiered stepped through-hole 17. A limiting platform 14 is connected to the top of the movable column 10, and the limiting platform 14 is located within the connection gap between the wooden frame 1 and the aluminum outer frame 2. A trigger plate 12 is connected to the bottom of the movable column 10. The trigger plate 12 is slidably connected to the three-tiered stepped through-hole 17 and extends beyond the three-tiered stepped through-hole 17. An inclined hole 11 is provided, which communicates with the three-step through hole 17. A second drainage through hole 13 is provided vertically on the trigger plate 12. A compression spring 9 is fitted on the moving column 10, which applies a downward elastic force to the trigger plate 12. A sealing ring 15 is installed at the top of the trigger plate 12, which seals the three-step through hole 17. The bottom of the trigger plate 12 is arc-shaped or wedge-shaped. The three-step through hole 17 and the moving column 10 are in clearance fit.

[0016] In specific work, such as Figures 1 to 2 As shown, when it rains or the weather is cold, people habitually close the windows. At this time, the trigger plate 12 on the aluminum outer frame 2 is squeezed by the window frame and retracts, so that the sealing ring 15 seals the three-step through hole 17. At this time, the window does not have a drainage function, but has good heat preservation performance. When the window is opened for ventilation after the rain stops, the rainwater is discharged in sequence through the first drainage through hole 5, the labyrinth flow hole 7, the inclined hole 11, the three-step through hole 17, and the second drainage through hole 13.

[0017] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
