Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a door and window structure for green buildings. Background Art

[0002] Doors and windows can be roughly divided into wooden doors and windows, steel doors and windows, plastic-steel doors and windows, aluminum alloy doors and windows, fiberglass doors and windows, stainless steel doors and windows, and iron flower doors and windows. Since the reform and opening up, people's living standards have continued to improve, the types of doors and windows and their derivative products have continued to increase, and the grade has gradually risen. Doors and windows, as architectural structures for ventilation and visual observation, are widely used in various buildings.

[0003] For example, a Chinese patent (publication number: CN214403325U) discloses a thermal insulation door and window for green buildings. In order to improve the flexibility of the thermal insulation door and window, a rotating hand wheel is embedded and connected at the middle position of the rear side of the transmission housing, and the interior of the window frame is symmetrically connected with push screws at both sides, and the outer side of the push screws is symmetrically connected with sleeve nuts, and the sleeve nuts are connected to the thermal insulation window through a push connecting rod. The utility model can drive the overall structure of the thermal insulation window to open and close by rotating the rotating hand wheel, replacing the traditional manual hard pushing form, which not only reduces the labor intensity of the staff, but also improves the air permeability and ventilation of the thermal insulation door and window. In the process of assembly and use, the thermal insulation window and the sealing plate are covered to keep the thermal insulation door and window strictly sealed, thereby ensuring that the thermal insulation door and window have good thermal insulation performance under the thermal insulation and sound insulation of the thermal insulation window.

[0004] The above-mentioned thermal insulation doors and windows for green buildings still have certain shortcomings. The worm gear transmission of the transmission worm and the transmission worm wheel drives the rotating rod to rotate, and synchronously drives the bevel gear A to rotate, and then drives the push screw to rotate through the mutual engagement of the teeth of the bevel gear A and the bevel gear B. While the push screw rotates, it drives the sleeve nut to slide symmetrically in the positioning slot through its symmetrically arranged positive and negative threads, and then drives the push connecting rod to rotate symmetrically, and pushes the thermal insulation window out from the inside of the window frame. The thermal insulation window is pushed to move by four pushing connecting rods. Not only is the movement unstable, but the thermal insulation window may also rotate under the blowing of the wind, affecting the installation of the thermal insulation window. Therefore, the present application proposes a door and window structure for green buildings to solve the above problems. Utility Model Content

[0039] Please refer again Figure 2 In order to facilitate the movement of the door and window body 1, the switch mechanism 3 in this embodiment includes a rotating component and a moving component. The rotating component includes a double-axis motor 301 fixed to the lower surface of the inner cavity of the window frame 2, a first rotating rod 302 fixed to the output shaft of the double-axis motor 301, a first bevel gear 303 fixed to the opposite sides of the two first rotating rods 302, two second rotating rods 305 rotatably connected between the upper and lower sides of the inner cavity of the window frame 2 through a bearing seat, a second bevel gear 304 fixed to the outer surface of the second rotating rod 305 and meshing with the first bevel gear 303, and a plurality of third bevel gears 306 fixed to the outer surface of the second rotating rod 305. The double-axis motor 301 drives the first rotating rod 302 and the first bevel gear 303 to rotate together, and drives the second bevel gear 304, the second rotating rod 305 and the two third bevel gears 306 to rotate together through the first bevel gear 303.

[0040] The moving component includes a fourth bevel gear 307 meshed with the outer surface of the third bevel gear 306, a threaded rod 308 fixed to the front face of the fourth bevel gear 307 and penetrating and extending to the outside of the window frame 2, and a rod sleeve 309 threadedly connected to the outer surface of the threaded rod 308.

Four limiting rods are fixed on the front of the window frame 2.

The fireproof layer 404 is glass fiber with good insulation, strong heat resistance, good corrosion resistance and high mechanical strength.

[0046] The protective mechanism 4 in this embodiment is composed of a pressure-resistant layer 401, a heat-insulating layer 402, a sound-insulating layer 403 and a fire-proof layer 404, which improves the pressure-resistant performance, heat-insulating performance, sound-insulating effect and fire-proof performance of the door and window body 1.

[0047] Please see Figure 5In order to improve the sealing performance, the sealing mechanism 7 in this embodiment includes a box body 701 fixed to the back of the door and window body 1, an electric push rod 702 fixed to the upper surface of the inner cavity of the box body 701, a moving block 703 fixed to the output end of the electric push rod 702, a plurality of hinged rods 704 hinged on the left and right sides of the moving block 703, a moving plate 705 hinged on the opposite sides of the left and right groups of hinged rods 704, a plurality of clamping rods 706 fixed to the opposite sides of the two moving plates 705, and a plurality of clamping grooves 707 opened on the left and right sides of the inner cavity of the fixed plate 6.

Two sliding rods are fixed between the left and right sides of the inner cavity of the box body 701, and the movable plate 705 is slidably connected to the outer surface of the sliding rod to increase the stability of the movable plate 705 when moving.

[0049] In the sealing mechanism 7 of this embodiment, the electric push rod 702 drives the moving block 703 to move, and the moving block 703 pushes the two moving plates 705 to move in opposite directions at the same time through the hinge rod 704. The moving plate 705 drives the clamping rod 706 to clamp into the inside of the clamping groove 707, thereby sealing and fixing the door and window body 1, and further improving the sealing and thermal insulation performance.

[0050] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power (provided by the battery) is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0051] The working principle of the above embodiment is:

[0052] (1) When the door and window body 1 needs to be opened, the dual-axis motor 301 is started. The dual-axis motor 301 drives the first rotating rod 302 to rotate, and drives the first bevel gear 303 to rotate through the first rotating rod 302. Through the rotation of the two first bevel gears 303, the two second bevel gears 304 are driven to rotate in the opposite direction at the same time, and the second rotating rod 305 is driven to rotate through the second bevel gear 304. Through the rotation of the second rotating rod 305, the two third bevel gears 306 are driven to rotate together, and through the third bevel gear 306, the fourth bevel gear 307 is driven to rotate together, and through the fourth bevel gear 307, the threaded rod 308 is driven to rotate. Since the left and right threaded rods 308 rotate in opposite directions and the thread directions are opposite, through the rotation of the threaded rod 308, the rod sleeve 309 and the door and window body 1 are driven to move together, so that the door and window body 1 is away from the window frame 2, which is convenient for opening the window for ventilation. On the contrary, the door and window body 1 can be closed to improve the thermal insulation.

[0053] (2) The protection mechanism 4 is composed of a pressure-resistant layer 401, a thermal insulation layer 402, a sound insulation layer 403 and a fireproof layer 404. The pressure-resistant layer 401 is made of polypropylene, which has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear resistance processing properties, and excellent mechanical properties, including tensile strength, compressive strength and hardness. The thermal insulation layer 402 is made of polyurethane, which has better stability, chemical resistance, resilience and mechanical properties, smaller compression deformation, good heat insulation, sound insulation, earthquake resistance and anti-toxic properties. The sound insulation layer 403 is a honeycomb sound-absorbing board, which has high flatness, high board strength, light weight, good sound absorption effect, fire resistance, waterproofness and easy installation. The fireproof layer 404 is made of glass fiber, which has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, thereby improving the pressure resistance, thermal insulation, sound insulation and fire resistance of the door and window body 1.

[0054] (3) When the door and window body 1 is fitted with the fixed plate 6, the electric push rod 702 is started, and the electric push rod 702 drives the moving block 703 to move, and the moving block 703 drives the hinge rod 704 to rotate. The moving block 703 pushes the two moving plates 705 to move in opposite directions at the same time through the hinge rod 704. The moving plate 705 slides on the outer surface of the sliding rod to increase the stability of the moving plate 705 when it moves. When the moving plate 705 moves, it drives the clamping rod 706 to be clamped into the inside of the clamping groove 707, thereby sealing and fixing the door and window body 1, and further improving the sealing and thermal insulation performance.
