Description

Technical Field

[0001] This utility model belongs to the field of composite door and window technology, specifically relating to an environmentally friendly composite door and window. Background Technology

[0002] Doors and windows are classified as enclosure components or partition components according to their location, and are an important part of the building envelope system.

[0003] Depending on the different design requirements, they have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing.

[0004] To improve lighting, transparent glass is usually installed inside the window sashes of doors and windows. Because the surface of the glass is smooth, it will produce specular reflection when sunlight shines directly on it, thus creating light pollution. If the reflection point is located on the road, the glare will affect the passage of vehicles and pedestrians, making it inconvenient for users. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly composite door and window with a simple structure and reasonable design in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An environmentally friendly composite door and window includes a rectangular frame profile. A horizontal bar is installed inside the frame profile. A mullion is fixedly installed between the upper surface of the middle section of the horizontal bar and the top wall of the inner cavity of the frame profile. Window sash profiles are rotatably connected to both sides of the mullion within the frame profile. A movable glass pane is installed within each window sash profile. Two ear plates are symmetrically installed at the top of the window sash profile on the exterior side. A retractor is rotatably connected between the two ear plates. A torsion spring is sleeved at the end of the retractor. One end of the torsion spring is fixed to the retractor, and the other end is fixed to the ear plate. A flexible light-shielding plate with a width consistent with the width of the inner cavity of the window sash profile is wound around the middle section of the retractor. Multiple polygonal protrusions are arranged in a matrix on the side of the flexible light-shielding plate away from the movable glass. Two symmetrically arranged hooks are fixedly connected to the end of the flexible light-shielding plate away from the retractor. Two suspension rods aligned with the hooks are installed at the bottom of the window sash profile on the exterior side.

[0008] As a further optimization of this utility model, a fixed glass is installed between the lower surface of the crossbar and the inner wall of the window frame profile, and sealant is applied to the periphery of the fixed glass at the connection between the crossbar and the window frame profile.

[0009] As a further optimization of this utility model, both the window frame profile and the window sash profile have a slot on the indoor side, and a solid wood board is provided inside the slot. The solid wood board is fixed to the window frame profile and the window sash profile through the slot.

[0010] As a further optimization of this utility model, the inner wall of the window sash profile is provided with an installation groove, the periphery of the movable glass is embedded in the installation groove, and a sealing strip is installed at the connection between the periphery of the movable glass and the inner wall of the installation groove.

[0011] As a further optimization of this utility model, an L-shaped handle is installed on one side wall of the window sash profile located indoors, and the horizontal section of the handle is fixed to the outer wall of the window sash profile near the mullion.

[0012] As a further optimization of this utility model, a sealing cover is also fixedly installed between the two ear plates. The sealing cover is located on the outside of the take-up shaft, and a through hole is provided on the bottom wall of the sealing cover for the flexible light-shielding plate to pass through at the end away from the take-up shaft.

[0013] The beneficial effects of this utility model are as follows: When sunlight shines directly on the screen, the flexible light-shielding plate can be unwound by pulling the winding shaft through the hook until the bottom end of the flexible light-shielding plate is fixed to the suspension rod through the hook. Since the flexible light-shielding plate has multiple matrix-distributed polygonal protrusions on the side away from the movable glass, the flatness of the outer surface of the flexible light-shielding plate can be reduced by the polygonal protrusions, and the light shining directly on the flexible light-shielding plate can be diffused and reflected to prevent the reflected light from converging. This minimizes the problem of glare that is easily formed when reflected light converges and shines on the road, affecting the passage of pedestrians and vehicles. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, an environmentally friendly composite door and window includes a rectangular frame profile 1. A horizontal bar 2 is horizontally installed inside the frame profile 1. A fixed glass 3 is installed between the lower surface of the horizontal bar 2 and the inner wall of the frame profile 1. Sealant is applied to the connections between the fixed glass 3 and the horizontal bar 2 and the frame profile 1. The sealant seals the connections between the fixed glass 3 and the horizontal bar 2 and the frame profile 1, improving the thermal insulation performance of the fixed glass 3.

[0021] A central mullion 4 is fixedly installed between the upper surface of the middle section of the horizontal bar 2 and the top wall of the inner cavity of the window frame profile 1. Window sash profiles 5 are rotatably connected to the window frame profiles 1 on both sides of the central mullion 4. The window frame profiles 1 and window sash profiles 5 are provided with slots on the indoor side. Solid wood boards 6 are provided inside the slots. Solid wood boards 6 are fixed to the window frame profiles 1 and window sash profiles 5 through the slots. This is used to combine the window frame profiles 1 and window sash profiles 5 with the solid wood boards 6 to form an integral structure, making the overall door and window structure more beautiful.

[0022] A movable glass 8 is provided inside the window sash profile 5. An installation groove 7 is provided on the inner side wall of the window sash profile 5. The movable glass 8 is embedded in the installation groove 7, so that the movable glass 8 is snapped and fixed to the window sash profile 5 through the installation groove 7. A sealing strip 9 is installed at the connection between the movable glass 8 and the inner wall of the installation groove 7 to seal the gap between the movable glass 8 and the inner wall of the installation groove 7.

[0023] A handle 10 in an L-shape is installed on one side wall of the window sash 5 located inside the room. The horizontal section of the handle 10 is fixed to the outer wall of the window sash 5 near the mullion 4. The handle 10 allows the user to open or close the window sash 5, making it convenient for the user.

[0024] Two ear plates 11 are symmetrically installed at the top of the window sash profile 5 on the outdoor side. A retractor 12 is rotatably connected between the two ear plates 11. A torsion spring 13 is sleeved at the end of the retractor 12. One end of the torsion spring 13 is fixed to the retractor 12, and the other end of the torsion spring 13 is fixed to the ear plate 11. When the retractor 12 rotates, it can drive the torsion spring 13 to rotate. When the external force disappears, the torsion spring 13 can drive the retractor 12 to rotate in the opposite direction under its own restoring force, so that the retractor 12 returns to its original position.

[0025] A sealing cover 14 is also fixedly installed between the two ear plates 11. The sealing cover 14 covers the outside of the winding shaft 12 and is used to protect the winding shaft 12 and torsion spring 13 inside it.

[0026] The middle section of the winding shaft 12 winds a flexible light-shielding plate 15 with a width consistent with the inner cavity width of the window sash profile 5. The side of the flexible light-shielding plate 15 away from the movable glass 8 is provided with multiple polygonal protrusions arranged in a matrix. The bottom wall of the sealing cover 14 is provided with a through hole for the end of the flexible light-shielding plate 15 away from the winding shaft 12 to pass through. Two symmetrically arranged hooks 16 are fixedly connected to the end of the flexible light-shielding plate 15 away from the winding shaft 12. Two suspension rods 17 are installed at the bottom of the window sash profile 5 on the outdoor side, which are aligned with the hooks 16. This allows the user to pull down the bottom of the flexible light-shielding plate 15 to drive the winding shaft 12 to rotate and unwind the flexible light-shielding plate 15. After unwinding, the flexible light-shielding plate 15 is pulled down to fix the hooks 16 to the suspension rods 17 and fix the flexible light-shielding plate 15.

[0027] It should be noted that when sunlight shines directly onto the movable glass 8 and through it into the room, causing discomfort to the people inside, this type of environmentally friendly composite door and window can be opened by using the handle 10 to open the window sash profile 5. Then, the hook 16 is pulled down, which pulls the retractor 12 to rotate, unrolling the flexible light-blocking panel 15 until the bottom end of the flexible light-blocking panel 15 is suspended and fixed to the hanging rod 17 installed on the bottom outer wall of the window sash profile 5 through the hook 16. Then, the window sash profile 5 can be closed again. Since the flexible light-blocking panel 15 is made of light-blocking material, it can block direct sunlight and reduce the interference of external light on the room.

[0028] Meanwhile, since the flexible light-shielding plate 15 has multiple matrix-distributed polygonal protrusions on the side away from the movable glass 8, the flatness of the outer surface of the flexible light-shielding plate 15 can be reduced by the polygonal protrusions, thus diffusely reflecting the light directly hitting the flexible light-shielding plate 15 and preventing the reflected light from converging. This minimizes the problem of glare that easily forms when reflected light converges onto the road, affecting pedestrian and vehicle traffic. The above-described embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
