DETAILED DESCRIPTION

[0024] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, this embodiment designs a heat-insulating water-blocking structure for an external casement window. The heat-insulating water-blocking structure is installed between the window sash and the window frame 5 when in use. A movable window installation opening is provided on the external casement window. The window sash is connected to the movable window installation opening of the window frame 5 through a hinge. The heat-insulating water-blocking structure is provided on the front side of the hinge and can block rainwater from flowing to the hinge to reduce the probability of rusting of the hinge. A heat-insulating strip installation groove 51 is provided on the inner wall of the movable window installation opening.

[0027] The window sash comprises a glass panel 1 and a glass sash 2 , wherein the glass sash 2 is installed around the glass panel 1 .

[0028] The heat-insulating water-retaining structure comprises two components: a water-retaining strip 3 and a heat-insulating strip 4 .

[0029] The water retaining strip 3 is generally made of soft rubber or silicone material. When in use, the water retaining strip 3 is installed on the outer peripheral side of the window sash glass 2. A front water retaining edge 31 is provided on the front part of the water retaining strip 3 facing away from the glass sash 2, and a rear water retaining edge 32 is provided on the rear part of the water retaining strip 3 facing away from the glass sash 2; the front water retaining edge 31 is located on the outdoor side of the rear water retaining edge 32.

[0030] The heat insulation strip 4 is installed on the inner wall of the movable window installation opening, and the cross section of the heat insulation strip 4 is T-shaped; the heat insulation strip 4 includes a transverse portion 42 and a longitudinal portion 45, the middle portion of the longitudinal portion 45 is vertically connected to the rear portion of the transverse portion 42, and a tapered portion 43 is provided at the front portion of the transverse portion 42; the thickness of the rear portion of the tapered portion 43 is less than the thickness of the transverse portion 42. A first step portion and a second step portion are respectively provided on opposite sides of the front portion of the heat insulation strip 4, and the first step portion and the second step portion are formed between the tapered portion 43 and the transverse portion 42. The thickness of the front portion of the tapered portion 43 is greater than the thickness of the rear portion. The slopes of the first step portion and the second step portion are both inclined.

[0031] The rear part of the heat insulating strip 4 can be connected to the rear part of the window frame 5 by snapping and being able to be turned forward and backward. Specifically, the rear part of the longitudinal part 45 is provided with a first connecting foot 411 and a second connecting foot 412, and the first connecting foot 411 and the second connecting foot 412 are mirror-symmetrical to each other. The heat insulating strip 4 is connected to the window frame 5 by snapping and being able to be turned forward and backward through the first connecting foot 411 and the second connecting foot 412. When the first connecting foot 411 and the second connecting foot 412 are both in the shape of a trapezoid with a small front and a large back, and are snap-connected to the rear side wall of the heat insulating strip installation groove 51 of the window frame 5, when the heat insulating strip 4 is turned forward, the first connecting foot 411 is located above the second connecting foot 412, and when the heat insulating strip 4 is turned backward, the first connecting foot 411 is located below the second connecting foot 412.

[0032] The front part of the thermal insulation strip 4 is connected with the front part of the window frame 5; a seepage gap is formed between the front part of the thermal insulation strip 4 and the front side wall of the thermal insulation strip installation groove 51, and water can enter the thermal insulation strip installation groove 51 through the seepage gap. A drain port is provided on the front groove wall of the thermal insulation strip installation groove 51, and the water flowing into the thermal insulation strip installation groove 51 can be discharged outward from the drain port. At the same time, since condensation water is easily generated in the thermal insulation strip installation groove 51, the rubber strip installed on the thermal insulation strip on the window frame 5 can separate the indoor and outdoor sides of the window frame 5 to prevent condensation water from flowing into the room, and the condensation water can be discharged outward through the drain port at the thermal insulation strip installation groove 51.

[0033] An angle bracket installation cavity 421 is provided inside the transverse portion 42 . When two mutually perpendicular heat insulation strips 4 are connected by an angle bracket, the angle bracket is inserted into the angle bracket installation cavity 421 to improve the flatness of the corner assembly of the window frame 5 .

[0034] The rear water retaining edge 32 is V-shaped and extends backward. When the glass fan 2 is closed, the front water retaining edge 31 contacts the insulation strip 4 and is sealed by extrusion. The front water retaining edge 31 is inclined forward to reduce the inflow of rainwater into the room.

[0035] When the structure of this embodiment is in use, after the window sash is closed, the rear water retaining edge 32 can abut against the rear edge of the heat insulation strip 4, thereby preventing water from seeping into the indoor direction. The front water retaining edge 31 abuts against the slope of the first step portion or the second step portion; a convex rib 44 is provided at the first step portion; depending on the usage scenario, the heat insulation strip 4 can be installed by forward rotation or reverse rotation; when the heat insulation strip 4 is forwardly rotated and connected to the window frame 5, the convex rib 44 faces away from the window sash, and the water between the water retaining strip 3 and the heat insulation strip 4 can be discharged forward through the gap between the front water retaining edge 31 and the second step portion; when the heat insulation strip 4 is reversely rotated and connected to the window frame 5, the convex rib 44 faces the window sash, and the convex rib 44 can prevent water from passing through the gap between the front water retaining edge 31 and the second step portion. When the convex rib 44 faces upward, it can block the water flow, and when the convex rib 44 faces downward, it can guide the water flow to drip downward.

[0036] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
