The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and/or" used herein includes any and all combinations of one or more related listed items.

The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

As shown in Figures 1-7, a casement window structure with an arc edge in one embodiment of the utility model includes a sash frame 1, a screen frame 2, a window frame 3 and a middle stile 4; the middle stile 4 is vertically connected to the window frame 3, so that the window frame 3 is divided into a first window frame and a second window frame; the first window frame and the second window frame are both fixedly installed with the sash frame 1, and the screen frame 2 is installed on the first window frame; the sash frame 1 is used to install the sash glass, and the screen frame 2 is used to install the screen; the top corners of the sash frame 1 and the screen frame 2 are both arc corners, and the side edge of the sash frame 1 against the sash glass and the side edge of the screen frame 2 against the screen are both arc edges.

In the utility model, the first window frame is the opening position of the casement window structure, and the second window frame is the fixed position of the casement window structure. The window sash glass of the first window frame is a glass sash, which can be opened and closed according to user needs, and a screen frame 2 is set in the first window frame, so that the window sash glass can also play a protective role when it is in an open state. In addition, the window sash glass of the second window frame is fixed glass. In addition, the top corners of the window sash frame 1 and the screen frame 2 are both set as arc angles. When the window sash glass is installed on the window sash frame 1 and the screen is installed on the screen frame 2, the overall aesthetics of the window sash can be guaranteed. The casement window structure with an arc angle can prevent dust from hiding, and is convenient for cleaning the window sash frame 1 and the screen frame 2. In addition, the side edge of the window sash frame 1 and the screen frame 2 that abuts against the window sash glass is set as an arc edge. In rainy weather, rainwater can flow out along the arc edge in time, reducing rainwater on the window sash. The occurrence of accumulation between the frame 1 and the window glass or between the screen frame 2 and the screen protects the window frame 1, the window glass, the screen frame 2 and the screen. At the same time, the arc-shaped edge decomposes the force exerted on the window frame 1 and the screen frame 2 to the surroundings, thereby improving the wind pressure resistance of the casement window structure, and solving the problem in the prior art that the top angle of the window frame 1 is a right-angle structure, which makes the window sash not beautiful, and the right-angle structure easily hides dust, which is not conducive to cleaning.

In one of the embodiments, the window sash frame 1 and the screen window frame 2 both include an inner frame edge 11, an inner baffle 12, an outer frame edge 13 and an outer baffle 14; the cross-sectional structure of the inner baffle 12 is compatible with the cross-sectional structure of the inner frame edge 11, and the cross-sectional structure of the outer baffle 14 is compatible with the cross-sectional structure of the outer frame edge 13; the inner frame edge 11 is connected to the inner baffle 12 to form an inner frame, and the outer frame edge 13 is connected to the outer baffle 14 to form an outer frame; the edges of the inner frame and the outer frame are both set as baffle edges 124; the baffle edges 124 are all arc-shaped edges, and the baffle edges 124 are curved, and when the inner frame edge 11 is connected to the inner baffle 12, and the outer frame edge 13 is connected to the outer baffle 14, the edges of the window sash frame 1 or the screen window frame 2 formed are all arc-shaped edges, and their top angles are all arc angles.

Specifically, the cross-sectional structure of the inner baffle plate 12 is adapted to the cross-sectional structure of the inner frame edge 11, and the cross-sectional structure of the outer baffle plate 14 is adapted to the cross-sectional structure of the outer frame edge 13. Thus, the connection between the inner frame edge 11 and the inner baffle plate 12 and the connection between the outer frame edge 13 and the outer baffle plate 14 can have a smooth transition, thereby ensuring the overall aesthetics of the window sash. At the same time, the arc-shaped edge plays a protective role.
