Description

Technical Field

[0001] The utility model relates to the field of metal doors and windows, in particular to a metal door and window with heat insulation and noise reduction. Background Art

[0002] With the improvement of the quality of life, people's requirements for the comfort of living environment are also increasing. Among them, doors and windows are an important part of the building, and their performance is directly related to the quality of the indoor environment. Traditional metal doors and windows, such as aluminum alloy doors and windows, steel doors and windows, etc., have long dominated the construction field. However, traditional metal doors and windows have obvious deficiencies in heat insulation and noise reduction, which is closely related to the large gap when they are closed.

[0003] Specifically, when traditional metal doors and windows are closed, there is often a large gap between the window frame and the window sash due to design, processing accuracy or installation. These gaps not only allow indoor and outdoor air to circulate freely, resulting in increased heat exchange and reduced thermal insulation performance of doors and windows; at the same time, these gaps also become channels for noise transmission, allowing external noise to easily enter the room, affecting people's rest and work. For this reason, we proposed a metal door and window with heat insulation and noise reduction. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a metal door and window with heat insulation and noise reduction, comprising a fixed frame, a movable frame is arranged inside the fixed frame, and glass is arranged inside the movable frame, and also includes:

[0008] A sealing strip is provided on one side of one end of the moving frame to increase the sealing performance;

[0009] A linkage component is arranged inside the movable frame to further increase the sealing performance. The linkage component is provided with multiple groups and are respectively arranged inside the mounting grooves. The multiple groups of linkage components include a movable box, a fixed shaft, a limit plate, a first spring group and a second spring group. The movable boxes are respectively slidably connected inside the mounting grooves, one end of the movable box is fixedly connected to one end of the second spring group, and the other end of the second spring group is fixedly connected to the inner wall of the mounting groove. A groove is provided inside the movable box, and the fixed shaft is fixedly connected to the two ends inside the movable box. One end of the limit plate is vertically arranged, and the other end of the limit plate is obliquely extended. The bending position of the limit plate is rotatably connected to the fixed shaft.

[0012] Preferably, mounting grooves are respectively formed at the top and the bottom of one end of the two movable frames that are away from each other.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a metal door and window with heat insulation and noise reduction, which has the following beneficial effects:

[0015] 1. The metal doors and windows with heat insulation and noise reduction have precise design and synergistic effect of linkage components. When the movable frame approaches the fixed frame to close, the movable box can push the inclined end of the limit plate outward by contacting and squeezing the fixed frame, thereby driving the packaging strip to expand outward, effectively filling the gap between the movable frame and the fixed frame. This design significantly reduces the possibility of indoor and outdoor air circulation and reduces heat exchange, thereby improving the thermal insulation performance of doors and windows. At the same time, the reduction of the gap also effectively blocks the channel for noise propagation, making the indoor environment quieter and helping to improve people's rest and working conditions.

[0016] 2. For the metal door and window with heat insulation and noise reduction, during the opening process of the moving frame, the movable box and the limit plate can quickly return to their initial positions through the reset force of the second spring group and the pulling force of the first spring group, and the packaging strip also shrinks accordingly, avoiding obstruction to the push and pull action of the moving frame. This design ensures smooth operation of the doors and windows when opening and closing, and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A metal door and window with heat insulation and noise reduction, comprising a fixed frame 1, a movable frame 2 is arranged inside the fixed frame 1, a glass 3 is arranged inside the movable frame 2, and further comprising:

[0024] A sealing strip 4 is provided on one side of one end of the moving frame 2 to increase the sealing performance;

[0025] A linkage component is arranged inside the movable frame 2 to further increase the sealing performance. A plurality of linkage components are provided and are respectively arranged inside the mounting grooves. The plurality of linkage components include a movable box 5, a fixed shaft 6, a limit plate 7, a first spring group 8 and a second spring group 10. The movable box 5 is respectively slidably connected inside the mounting grooves. One end of the movable box 5 is fixedly connected to one end of the second spring group 10. The other end of the second spring group 10 is fixedly connected to the inner wall of the mounting groove. A groove is provided inside the movable box 5. The fixed shaft 6 is fixedly connected to both ends of the inner part of the movable box 5. One end of the limit plate 7 is vertically arranged, and the other end of the limit plate 7 is inclined and extended. 7 is rotatably connected to the fixed shaft 6, the two ends of the first spring group 8 are fixedly connected between the vertical ends of the limit plate 7, and the outer wall of the inclined end of the limit plate 7 is fixedly connected with a packaging strip 9. This improvement significantly reduces the free circulation of indoor and outdoor air, thereby reducing heat exchange and greatly improving the thermal insulation performance of doors and windows. At the same time, the reduction in gaps also effectively blocks the channel for noise propagation. When the moving frame 2 needs to be opened, the reset force of the second spring group 10 will help the movable box 5 return to its initial position. At the same time, the pulling force of the first spring group 8 causes the inclined end of the limit plate 7 to shrink inward, and the packaging strip 9 also shrinks accordingly, avoiding obstruction to the push-pull action of the moving frame 2.

[0026] Furthermore, a slide groove is provided inside the fixed frame 1 , and the movable frame 2 is provided with two slide grooves respectively slidably connected to the inside of the fixed frame 1 , and the sealing strip 4 is fixedly connected to one side adjacent to the two movable frames 2 .

[0027] Furthermore, the length of the sealing strip 4 is equal to the length of the glass 3 , and the sealing strip 4 is made of fluororubber, which is a high-temperature-resistant and corrosion-resistant material with excellent performance.

[0028] Furthermore, installation grooves are respectively provided at the top and bottom of the ends of the two movable frames 2 that are away from each other. When the movable frame 2 approaches the fixed frame 1 to close, the movable box 5 slides along the installation groove under the push of the movable frame 2. During the sliding process of the movable box 5, due to the action of the fixed shaft 6, the vertical end of the limit plate 7 will be squeezed with the two ends of the first spring group 8. This squeezing will cause the inclined end of the limit plate 7 to open outward and drive the packaging strip 9 fixedly connected thereto to expand outward. The expansion of the packaging strip 9 effectively fills the gap between the movable frame 2 and the fixed frame 1, thereby enhancing the sealing effect. After filling, the limit plate 7 is squeezed by the packaging strip 9, the limit plate 7 squeezes the movable box 5, and then the movable box 5 squeezes the second spring group 10 to shrink into the installation groove, thereby increasing its sealing effect.

[0029] Working principle: When the moving frame 2 approaches the fixed frame 1 to close, the movable box 5 slides along the installation slot under the push of the moving frame 2. During the sliding process of the movable box 5, due to the action of the fixed shaft 6, the vertical end of the limit plate 7 will be squeezed with the two ends of the first spring group 8. This squeezing will cause the inclined end of the limit plate 7 to open outward and drive the packaging strip 9 fixedly connected to it to expand outward. The expansion of the packaging strip 9 effectively fills the gap between the moving frame 2 and the fixed frame 1, thereby enhancing the sealing effect. After filling, the packaging strip 9 squeezes the limit plate 7, the limit plate 7 squeezes the movable box 5, and then the movable box 5 The second spring group 10 is squeezed and shrunk into the installation groove to increase its sealing effect. In this process, the second spring group 10 provides a reset force for the movable box 5. When the movable frame 2 needs to be opened, the reset force of the second spring group 10 will help the movable box 5 return to its initial position. At the same time, the inclined end of the limit plate 7 is retracted inwardly through the pulling force of the first spring group 8, and the packaging strip 9 is also retracted, avoiding obstruction to the push-pull action of the movable frame 2. This improvement significantly reduces the free circulation of indoor and outdoor air, thereby reducing heat exchange and greatly improving the thermal insulation performance of doors and windows. At the same time, the reduction in gaps also effectively blocks the channel for noise propagation.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
