Description

Technical Field

[0001] The utility model relates to the technical field of door and window manufacturing, and in particular to a hinge and screen window structure. Background Art

[0002] The existing door and window systems are mainly divided into casement windows and sliding windows. Casement windows are widely used in building decoration due to their large opening area, good ventilation, good sealing, sound insulation, heat preservation and excellent anti-seepage performance. Casement windows are divided into inward opening and outward opening according to the opening method: the advantage of inward opening is that it is convenient to clean the window; the advantage of outward opening is that it does not take up space when opened, but the disadvantage is that the field of vision is not wide. In order to have a wide field of vision, the inward opening structure is often used.

[0003] The screen fan is divided into invisible screen fan and non-invisible screen fan. The invisible screen fan is widely used because the screen fan hinge connecting the screen fan and the window frame is hidden at the connection between the screen fan and the window frame when it is closed, which looks more beautiful from the outside. The screen fan hinge is generally installed at the corner of the window frame. Therefore, the widely used aluminum profile window frame has a corresponding part with a reserved installation slot as the screen fan hinge fixing part. The screen fan hinge is specially used for the opening and closing control of the screen fan and the window frame. Generally, when it is opened, an opening and closing angle is formed between the screen fan and the window frame.

[0004] However, existing double-leaf inward-opening windows generally have window sashes and screen sashes arranged in sequence from the inside to the outside. Since the window sashes and the screen sashes are fixed on the same side of the window frame at the same time, when the window sashes are opened, the screen sashes are difficult to fully open inwards due to the thickness of the window sashes, and the maximum opening and closing angle of the screen sash is about 60°, which affects the user experience.

[0036] like Figure 1 and Figure 2 As shown, a hinge in one embodiment of the utility model includes a mounting base 1, a first connecting rod 2 and a second connecting rod 3: the mounting base 1 is provided with a mounting hinge position 11 and a sliding long groove 12, the first connecting rod 2 is provided with a sliding end 21, a hinge portion 22 and a mounting portion 23, the sliding end 21 is slidably connected to the sliding long groove 12, and the mounting portion 23 is used to install a screen window; the second connecting rod 3 is provided with a hinge end 31 hinged to the mounting hinge position 11, and a connecting end 32 hinged to the hinge portion 22.

[0037] The above-mentioned hinge is arranged to fix the mounting base 1 of the hinge on the window frame, and the screen fan is installed on the mounting part 23. When the screen fan is swung toward the room, the sliding end 21 of the first connecting rod 2 is slidably connected on the sliding long groove 12. The maximum opening angle of the screen fan relative to the mounting plane of the window frame can reach 90°, thereby reducing the space occupied by the screen fan, facilitating a wide field of vision, and improving the user experience.

[0038] In one embodiment, the sliding end 21 is slidably connected to the sliding long slot 12 through the connecting structure 4; the connecting structure 4 includes a limiting shaft head 41 rotatably connected to the sliding end 21, and a limiting groove 42 arranged in the sliding long slot 12, and the limiting shaft head 41 is provided with a connecting shaft rod 43 passing through the sliding long slot 12, and a limiting shoulder end 44 adapted to the width of the limiting groove 42. In this way, the thickness of the hinge is reduced by the connecting structure 4, which is conducive to reducing the installation size and ensuring a wide field of view of the inner frame of the double-leaf inward-opening window.

[0039] In one embodiment, the first connecting rod 2 includes a connecting rod body 201 and a mounting plate 202 disposed on the connecting rod body 201; the mounting plate 202 is an L-shaped bent plate as a whole, including a horizontal plate and a vertical plate; the mounting portion 23 includes a connecting position 231 disposed on the vertical plate, and a top position 232 disposed on the horizontal plate. In this way, by splitting the first connecting rod 2 into the connecting rod body 201 and the mounting plate 202 connected together, it is convenient to strengthen the structural strength of the first connecting rod 2; at the same time, according to the different structures of the connecting rod body 201 and the mounting plate 202, different processing techniques are performed to reduce production costs.
