Description

Technical Field

[0001] The utility model belongs to the technical field of building doors and windows, and in particular relates to an inner-hinged outer casement window structure. Background Art

[0002] In order to increase the service life of hinges, some outward-opening window structures adopt the method of installing hinges on the indoor side of doors and windows to increase the service life of hinges. In order to achieve waterproof sealing of windows, it is often necessary to install the central rubber strip on the window sash of casement sashes. Since the central rubber strip is often installed after the door and window sashes are installed, due to factors such as the obstruction of hinges and the position of the window sash after opening, the installation of some rubber strips on the window sash is difficult and inefficient.

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 an internally hinged external casement window structure, including components such as a window sash, a hinge 5, a window frame, a window sash insulation strip 3, a front rubber strip 4, a rear rubber strip 6 and a window frame insulation strip 7.

[0027] The window sash includes a glass sash and an outer frame, and the outer frame is installed around the glass sash. The window rear side of the window frame is connected to the window sash through a hinge 5. The front side of the window frame or the front side of the window sash in this embodiment is the left side in the figure, which is also the outdoor side after the external casement window is installed; the rear side of the window frame or the rear side of the window sash in this embodiment is the right side in the figure, which is also the indoor side after the external casement window is installed. The inner side in this embodiment refers to the side close to the glass sash, and the outer side refers to the side away from the glass sash.

[0028] The outer periphery of the window sash is provided with a window sash heat insulation strip 3, and the front and rear parts of the inner side of the window sash heat insulation strip 3 are respectively engaged with different parts of the window sash outer frame, and the outer periphery of the window sash heat insulation strip 3 is provided with an external extension convex portion 31. A T-shaped window frame heat insulation strip 7 is installed around the front side of the window, and a rear step portion 71 is formed at the rear of the window frame heat insulation strip 7, and a rear rubber strip 6 is installed on the front side of the rear step portion 71, and a rubber strip installation groove 76 is provided on the front side of the rear step portion 71, and the rear rubber strip 6 is embedded in the rubber strip installation groove 76. When the window sash is in a closed state, the inner side of the rear rubber strip 6 can overlap with the external extension convex portion 31 to prevent water from flowing backwards.

[0029] In the above structure, since the rear rubber strip 6 only needs to be installed on the window frame insulation strip 7, and does not need to be installed on the window sash, the difficulty of installing the rear rubber strip 6 can be reduced, the installation efficiency can be improved, and the labor cost can be reduced. The inner and outer sides of the T-shaped window sash insulation strip 3 can form a continuous stepped structure, so that the surface of the window frame insulation strip 7 is smooth, the drainage performance and easy cleaning performance are greatly improved, and the drainage and easy cleaning performance are effectively improved.

[0030] The inner and outer sides of the rear part of the window frame heat insulation strip 7 are symmetrical to each other, and a connecting foot is provided on the rear side of the rear step portion 71, and the rear part of the window frame heat insulation strip 7 is connected to the window frame by the connecting foot. Therefore, when the window frame heat insulation strip 7 is installed by rotating it forward and backward (i.e., rotating it inside and outside), the installation of the rear rubber strip 6 can be met, and the sealing requirements when the window sash is closed can also be met, avoiding the rework caused by the construction workers installing the window frame heat insulation strip 7 upside down. The rubber strip installation grooves 76 of two adjacent and perpendicular window frame heat insulation strips 7 are connected, and when the rear rubber strip 6 is installed, the rear rubber strip 6 can be directly bent at the corner position to achieve installation.

[0031] A front rubber strip 4 is provided on the outer periphery of the front side of the window sash, and a front step portion 72 is provided on the front part of the window frame heat insulation strip 7. The front step portion 72 overlaps with the vertical surface of the front rubber strip 4 to prevent water from flowing backward. The inner and outer sides of the front part of the window frame heat insulation strip 7 are symmetrical to each other. When the window frame heat insulation strip 7 is installed forward and reversely, the installation of the rear rubber strip 6 can be met, and the sealing requirement when the window sash is closed can also be met. The front rubber strip 4 and the front step portion 72 form an overlapping structure, which can effectively prevent rainwater from flowing to the inner side of the room and better protect the hinge 5.

[0032] The step surface on the front side of the front step portion 72 is located outside the step surface on the rear side thereof, and a ridge 75 perpendicular to the step surface is provided at the front step portion 72. The ridge 75 close to the window sash is used to block the water flow forward, and the ridge 75 away from the window sash is used to guide the water flow. When rainwater flows to a ridge 75 below the lowermost window frame insulation strip 7, water droplets can flow downward along the ridge 75 without seeping into the indoor side, thereby improving the water-isolating effect between the indoor side and the outdoor side of the casement window.

[0033] The front end surface of the window frame heat insulation strip 7 is provided with an overlapping protrusion 73 protruding forward, and the overlapping protrusion 73 overlaps the front side of the fixed window frame 2.

[0034] An angle code installation cavity 74 is provided in the window frame heat insulation strip 7, and the angle code installation cavity 74 is used for plugging and connecting angle codes to achieve the connection of two adjacent and perpendicular window frame heat insulation strips 7 to improve the flatness of the splicing of the window frame.

[0035] In addition, since the present embodiment adopts the window sash insulation strip 3 and the window frame insulation strip 7, it can not only achieve heat insulation between the indoor and outdoor sides of the window sash, but also achieve heat insulation between the indoor and outdoor sides of the window frame, thereby improving the heat insulation effect.

[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.
