Description

Technical Field

[0001] The utility model relates to the technical field of inward-opening doors and windows, in particular to a door and window which can effectively increase the tightness of a frame and leaf. Background Art

[0002] Doors and windows are divided into enclosure components or partition components according to their location. They have different design requirements and should have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fire prevention. The new requirements are energy saving. In cold areas, the heat lost through the gaps in doors and windows accounts for about 25% of the total heating heat consumption. The airtightness requirements of doors and windows are an important part of energy-saving design.

[0003] In the prior art, the sealing of inward-opening doors and windows is generally achieved by utilizing flexible rubber strips to achieve a tight contact between the window frame and the inward-opening sash, but since the inward-opening sash and window frame of the inward-opening doors and windows are generally installed through hinges, the inward-opening sash and the window frame generally have an angle. During the closing process of the doors and windows, the force applied to the rubber strips at both ends is uneven. Specifically, the force applied to the rubber strips close to the hinges is greater, while the force applied to the rubber strips away from the hinges is less. Therefore, it is easy for the rubber strip at the end away from the hinges to not be in contact with the window frame, resulting in air leakage in the doors and windows, and causing poor sealing of the doors and windows. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a door and window that can effectively increase the tightness of the frame and sash, so as to solve the technical problems mentioned in the above background technology.

[0007] Furthermore, a sealing piston is arranged inside the cavity and fixedly connected to the push-pull rod. A side of the sealing piston away from the push-pull rod is provided with a plurality of elastic plates fixedly connected to the inner wall of the cavity.

[0008] Furthermore, a first rubber strip is fixedly connected to a side of the upper end of the window cross beam away from the support frame, and a second rubber strip is fixedly connected to a side of the bottom end of the movable beam away from the extension frame.

[0009] Furthermore, the hinge is composed of two connecting pieces and a connecting shaft connected to each other, and one of the connecting pieces is fixedly connected to the inward opening sash, and the other connecting piece is slidably connected to the window frame.

[0010] Furthermore, sealing strips are fixedly installed on opposite sides of the support frame and the extension frame.

[0011] Furthermore, one end of the push-pull rod away from the sealing piston passes through the movable beam, and a positioning plate is provided at one end of the push-pull rod passing through the movable beam.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1 - Figure 5 The utility model discloses a door and window which can effectively increase the tightness of the frame and sash, comprising a window frame 1 and an inner opening sash 2, wherein the window frame 1 is a rectangular frame formed by connecting four window cross beams 3 in sequence, and the inner opening sash 2 is a rectangular frame formed by connecting four movable beams 4 in sequence, a hinge 5 is arranged at one end of the inner opening sash 2, and one end of the hinge 5 is fixedly connected to the window frame 1, an extension frame 6 is arranged at the bottom end of one side of the movable beam 4, a support frame 7 is arranged at the side of the upper end of the window cross beam 3 away from the extension frame 6, a cavity 8 is arranged inside the movable beam 4, a plurality of evenly distributed push-pull rods 9 are arranged at one end of the cavity 8 close to the support frame 7, and an exhaust hole 10 penetrating the movable beam 4 is arranged at the bottom end of the side of the cavity 8 away from the push-pull rod 9.

[0025] In this embodiment, when in use, the window frame 1 is fixed at the position of the reserved hole, and the inner opening fan 2 is fixed to one side of the window frame 1 by the hinge 5. When the inner opening fan 2 and the window frame 1 are closed, the inner opening fan 2 is pushed to rotate so that the inner opening fan 2 gradually contacts with the window frame 1 and the inner opening fan 2 gradually fits closely with the support frame 7. At this time, the extension frame 6 and the window cross beam 3 fit closely with each other. Through the setting of the push-pull rod 9, when the inner opening fan 2 gradually fits closely with the support frame 7 (that is, the movable frame gradually fits closely with the support frame 7), the support frame 7 will push the push-pull rod 9 to move the push-pull rod 9 toward the inside of the cavity 8 to compress the air inside the cavity 8, so that the air enters the gap between the window cross beam 3 and the movable beam 4 through the exhaust hole 10, thereby increasing the air pressure in the gap and making it difficult for outside air to enter the gap between the window cross beam 3 and the movable beam 4, thereby achieving the effect of improving the sealing between the window frame 1 and the inner opening fan 2.

[0026] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a sealing piston 11 is arranged inside the cavity 8 and the sealing piston 11 is fixedly connected to the push-pull rod 9 . A plurality of elastic plates 12 fixedly connected to the inner wall of the cavity 8 are arranged on the side of the sealing piston 11 away from the push-pull rod 9 .

[0027] In this embodiment, the sealing piston 11 is provided to facilitate the movement of the air inside the cavity 8, thereby achieving the effect of facilitating the exhaust of air, and the elastic plate 12 is provided to facilitate the reset of the sealing piston 11 when the door or window is opened.

[0028] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a first rubber strip 13 is fixedly connected to a side of the upper end of the window cross beam 3 away from the support frame 7 , and a second rubber strip 14 is fixedly connected to a side of the bottom end of the movable beam 4 away from the extension frame 6 .

[0029] In this embodiment, the first rubber strip 13 is trapezoidal in shape and hollow inside and is made of a relatively soft colloid material. The second rubber strip 14 is of the same shape and material as the first rubber strip 13. When the air inside the cavity 8 enters the gap between the movable beam 4 and the window cross beam 3, the air pressure squeezes the first rubber strip 13 and the second rubber strip 14 at the same time, causing the first rubber strip 13 and the second rubber strip 14 to deform, thereby blocking the contact portion between the movable beam 4 and the window cross beam 3, thereby achieving the effect of improving the sealing performance.

[0030] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the hinge 5 is composed of two connecting pieces 51 and a connecting shaft 52 connected to each other, and one of the connecting pieces 51 is fixedly connected to the inner opening fan 2, and the other connecting piece 51 is inserted into the interior of the window frame 1 and is slidably connected to the window frame 1.

[0031] In this embodiment, when opening the inner sash 2, the inner sash 2 is pulled out vertically from the inside of the window frame 1, and the hinge 5 is rotated to complete the opening of the door and window. When closing the door and window, the hinge 5 is rotated to make the inner sash 2 correspond to the window frame 1, and the inner sash 2 is pushed to make the hinge 5 inserted into the inside of the window frame 1, so as to achieve the effect of closing the window frame 1, and effectively enable the inner sash 2 to be vertically inserted into the inside of the window frame 1, thereby achieving the effect of improving the airtightness.

[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a sealing strip 15 is fixedly mounted on the opposite sides of the support frame 7 and the extension frame 6 .

[0033] In this embodiment, by providing the sealing strip 15, the contact between the window frame 1 and the inner opening sash 2 is made closer, thereby achieving the effect of improving the sealing performance of the door and window.

[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, one end of the push-pull rod 9 away from the sealing piston 11 passes through the movable beam 4 , and a positioning plate 16 is provided at one end of the push-pull rod 9 passing through the movable beam 4 .

[0035] In this embodiment, the positioning plate 16 is provided to achieve the purpose of positioning the moving distance of the push-pull rod 9, thereby avoiding the problem of the push-pull rod 9 being embedded in the cavity 8 and getting stuck.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
