Description

Technical Field

[0001] The utility model relates to the technical field of airtight windows, and particularly refers to a structure of a push-down type casement window frame. Background Art

[0002] With the progress of society and the development of technology, people have gradually realized the importance of the airtightness of building envelope structures for indoor environmental quality and energy efficiency. Traditional window designs often have gaps, resulting in cold air infiltration and heat loss, which not only affect indoor comfort but also increase energy consumption. In the context of increasingly serious energy crises and environmental problems, improving the airtightness of building envelope structures has become one of the important means of energy conservation and emission reduction.

[0003] At present, the deficiencies of airtight windows on the market are as follows: 1. The market generally uses a push-type sub-frame, and it is easy to have problems in production and manufacturing where the contact is not in place; 2. The influence of weather is not considered in the overlap at the opening position, especially in bad weather, which is likely to cause water backflow and water seepage. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a structure of a push-down type casement window frame to solve the technical problem of poor sealing effect of airtight windows.

[0005] In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

[0006] A structure of a push-down type casement window frame includes a bottom frame, the bottom frame is installed on a wall, and a push-down and push-type sub-frame is arranged on the bottom frame;

[0007] The bottom frame includes an outer bottom frame and an inner bottom frame, and the outer bottom frame and the inner bottom frame are connected by two groups of connecting bottom frames;

[0008] The sub-frame includes an outer sub-frame matched with the outer bottom frame and an inner sub-frame matched with the inner bottom frame, and the outer sub-frame and the inner sub-frame are connected by two groups of connecting sub-frames; an outer sash frame is connected to the upper end of the outer sub-frame, and an inner sash frame is connected to the upper end of the inner sub-frame.

[0009] Preferably: Bottom frame support plates connected to the wall are arranged at the lower ends of the outer bottom frame and the inner bottom frame.

[0010] Preferably: An outer connecting plate of the sub-frame for connecting with the outer bottom frame is fixedly arranged on one side of the outer sub-frame away from the connecting sub-frame.

[0011] Preferably: A vertical sub-frame vertical plate is fixedly arranged on one side of the outer sub-frame close to the connecting sub-frame, a vertical plate connecting plate is arranged on the side of the sub-frame vertical plate away from the outer sub-frame, a connecting frame is connected at the sub-frame vertical plate and the vertical plate connecting plate, and the inner sash frame is connected to the connecting frame.

[0012] Preferably: an arc-shaped inner rubber plate is provided in the middle of the side of the inner sub-frame away from the connecting sub-frame, a bottom rubber plate is provided at the lower end of the inner sub-frame close to the connecting sub-frame, and expansion rubber strips are installed on both the inner rubber plate and the bottom rubber plate.

[0013] Preferably, the expansion strip is a water-expandable strip.

[0014] Beneficial effects of the utility model:

[0015] The sub-frame adopts a downward-pressed flat-open structure. By increasing the contact surface between the sub-frame and the bottom frame, a closed loop is formed inside, effectively isolating water from seeping inward, thereby better diverting water to the drainage outlet of the bottom frame.

[0016] The expansion rubber strip is provided to improve the sealing of the connection between the sub-frame and the bottom frame, thereby effectively improving the windproof and waterproof effect of the window sash.

[0017] The expansion strips are water-expandable. Whenever it rains and rainwater enters the window, the strips will expand rapidly to seal the gap between the sub-frame and the bottom frame, effectively solving the problems of water backflow and water seepage caused by insufficient sealing of the sub-frame.
