Description

Technical Field

[0001] This utility model relates to the technical field of door and window profile components, specifically to a door and window profile component. Background Technology

[0002] A door frame, also known as a door panel, generally consists of two vertical side panels and a top frame. When the door has a transom, there is also a middle horizontal frame; multi-panel doors also have middle vertical frames. The door frame is the connecting component between the door leaf, transom, and the wall. The cross-sectional shape of the door frame is related to the type and number of layers of the door. It should also facilitate door installation and have a certain degree of airtightness. As shown in the figure, the cross-sectional dimensions of the door frame mainly consider the strength of the joints and the type of door, as well as the finishing waste during manufacturing. The rough cross-sectional dimension should be larger than the net cross-sectional dimension.

[0003] Door and window profiles are the basic elements that make up door and window frames and structures. Through combination and installation, they form door and window products with specific functions and appearances. These components are usually made of different materials, such as wood, metals (e.g., aluminum alloys, stainless steel, steel), and plastics (e.g., PVC, uPVC), to meet different performance requirements, such as strength, durability, thermal insulation, sound insulation, and aesthetics.

[0004] In existing aluminum alloy door and window profiles, a thermal break structure is typically used. The thermal insulation effect is achieved by a thermal break strip placed in the middle of the outer frame. However, most existing insulated door and window profiles have the inner frame with the glass installed attached to the thermal break strip. In order to reduce the gap between the inner and outer frames and improve the thermal insulation effect, the inner frame is directly installed on the thermal break strip, and the thermal break strip bears the weight of the inner frame and the glass. This puts greater pressure on the thermal break strip during use, making it prone to cracking and bursting during long-term use, resulting in damage and deformation of the door and window components. Utility Model Content

[0005] The purpose of this application is to provide a door and window profile component to solve the problem that existing thermal insulation strips are prone to cracking and bursting due to excessive pressure during use, which causes damage and deformation of door and window components.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A door and window profile component includes an outer frame, an inner frame installed at the upper end of the outer frame, glass fixedly connected to the inner wall of the inner frame, a connecting strip fixedly connected inside the outer frame, an arc-shaped limiting plate fixedly connected inside the outer frame, the arc-shaped limiting plate being fixedly connected to the connecting strip, a heat insulation strip being provided at the upper end of the connecting strip, an arc-shaped groove being provided inside the sliding strip, a heat insulation groove being provided inside the heat insulation strip, and a thermal insulation structure being provided between the outer frame and the inner frame.

[0008] By adopting the above technical solution, when the device is used for heat insulation, the heat insulation strip will block the cold air when it passes through the aluminum outer frame and inner frame, and conduct the temperature downward. The heat insulation structure slows down the temperature transfer, allowing it to enter the thermal break of the outer frame, making it difficult for cold air to be transferred from outside the window to inside. Furthermore, when the inner frame moves the glass, the heat insulation structure can support the inner frame, preventing the heat insulation strip from bursting and damaging the outer frame. The heat insulation structure can also better block the gap between the inner and outer frames, resulting in better heat insulation performance.

[0009] Furthermore, the thermal insulation structure includes a thermal insulation layer formed inside the outer frame, and a sliding strip is fixedly connected inside the outer frame, with the lower end of the sliding strip abutting against the thermal insulation strip.

[0010] By adopting the above technical solution, when the cold air flows through the aluminum outer frame and inner frame, it will first contact the sliding strip and move towards the thermal insulation strip. Then, the thermal insulation strip will block the cold air and conduct the temperature downwards to the connecting strip. The thermal insulation layers on both sides will block and slow down the temperature transfer, allowing it to enter the thermal break of the outer frame, making it difficult for the cold air to be transferred from outside the window to inside.

[0011] Furthermore, a fixing strip is fixedly connected to the upper end of the outer frame, and an abutment strip is slidably connected to the upper end of the outer frame. Guide strips are fixedly connected to the upper ends of both the fixing strip and the abutment strip. A guide groove is provided at the lower end of the inner frame, and the shape of the guide groove is adapted to the guide strip.

[0012] By adopting the above technical solution, when the inner frame moves the glass, the sliding strip at the lower end of the inner frame will move in conjunction with the moving strip, and the inner frame will be guided by the guide strip to make its movement more stable.

[0013] Furthermore, an inclined strip is fixedly connected to one side of the sliding strip, and a movable strip is fixedly connected to the lower end of the inner frame. An inclined groove is provided in the movable strip, and the shape of the inclined groove is adapted to the inclined strip. Diamond-shaped limiting strips are fixedly connected to both ends of the heat insulation strip, and the diamond-shaped limiting strips are slidably connected to the outer frame.

[0014] By adopting the above technical solution, the inclined strip will move in the inclined groove and fill the gap between the contact strip and the inner frame.

[0015] Furthermore, a lifting spring is fixedly connected inside the outer frame, and the upper end of the lifting spring is fixedly connected to the abutment strip.

[0016] By adopting the above technical solution, the lifting spring continuously pushes the contact strip upward, keeping the contact strip constantly pushing the inner frame upward, making it less likely for the heat insulation strip to burst and damage the outer frame.

[0017] Furthermore, a guide strip is fixedly connected inside the outer frame, and the guide strip is slidably connected to the abutment strip.

[0018] By adopting the above technical solution, the contact strip always pushes the inner frame upward, allowing the contact strip to move along the guide strip to make its support of the inner frame more stable.

[0019] Furthermore, an installation strip is slidably provided on the outer surface of the outer frame, one side of the installation strip abuts against the inner frame, and one end of the installation strip is threadedly connected to a bolt, which is threadedly connected to the outer frame.

[0020] By adopting the above technical solution, the bolt is rotated so that its end is no longer connected to the outer frame, and then the mounting strip is removed, leaving a larger installation space on one side of the outer frame. Next, the inner frame is installed inside the outer frame. After the inner frame is installed, the mounting strip is attached to the inner frame, and the bolt is rotated to fix the mounting strip to the outer frame.

[0021] Furthermore, a filler sleeve is slidably connected to the outer surface of the mounting strip. The filler sleeve is a flexible rubber sleeve. A sliding post is fixedly connected inside the filler sleeve. The end of the sliding post is fixedly connected to the mounting strip. An anti-collision spring is fixedly connected inside the mounting strip. The end of the anti-collision spring is fixedly connected to the flexible rubber sleeve.

[0022] By adopting the above technical solution, as the spring returns to its original position, it pushes the filling sleeve to fill the gap between the inner frame and the fixing strip, allowing the filling sleeve to move along the sliding post towards the gap, thus making the gap filling more compact.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when cold air flows through the aluminum outer and inner frame components, it first contacts the sliding strip and moves towards the thermal insulation strip. The thermal insulation strip then blocks the cold air, conducting the heat downwards to the connecting strip. The heat is then slowed down by the thermal insulation layers on both sides, allowing the air to enter the thermal break of the outer frame component, preventing cold air from easily transferring from outside to inside the window. When the inner frame component moves the glass, the sliding strip at the lower end of the inner frame component moves in conjunction with the moving strip. The inner frame component is guided by the guide strip to move. More stable, the inner frame is supported and supported by the abutment strip and the fixing strip on both sides. As the lifting spring continues to push the abutment strip upward, it pushes the inner frame upward, allowing the abutment strip to move along the guide strip to make its support of the inner frame more stable. At the same time, the tilting strip will move in the tilting groove and fill the gap between the abutment strip and the inner frame, making it less likely for the heat insulation strip to burst and damage the outer frame. It can also better cover the gap between the inner and outer frames, making the heat insulation effect of the device better.

[0025] 2. In this application, when installing the inner frame, first rotate the bolts so that their ends are no longer connected to the outer frame, then remove the mounting strip to leave a larger installation space on one side of the outer frame. Next, install the inner frame inside the outer frame. After installing the inner frame, attach the mounting strip to the inner frame and rotate the bolts to fix the mounting strip to the outer frame. As the mounting strip moves towards the inner frame, the filling sleeve is squeezed by the inner frame and the fixing strip, causing the contact spring to extend and retract. As the spring returns to its original position, it pushes the filling sleeve to fill the gap between the inner frame and the fixing strip, allowing the filling sleeve to move along the sliding post towards the gap, making the filling of the gap more compact. This makes the installation of the inner and outer frame components more convenient and further improves the thermal insulation effect of the device. Attached Figure Description

[0033] The following will be based on the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Reference Figure 1 and Figure 3 This utility model provides a technical solution: a door and window profile component, including an outer frame 1, an inner frame 2 installed on the upper end of the outer frame 1, glass 3 fixedly connected to the inner wall of the inner frame 2, a connecting strip 8 fixedly connected inside the outer frame 1, an arc-shaped limiting plate 9 fixedly connected inside the outer frame 1, the arc-shaped limiting plate 9 and the connecting strip 8 fixedly connected, a heat insulation strip 10 provided at the upper end of the connecting strip 8, an arc-shaped groove opened inside the sliding strip 12, a heat insulation groove opened inside the heat insulation strip 10, and a heat insulation structure provided between the outer frame 1 and the inner frame 2.

[0035] When this device is used for heat insulation, the heat insulation strip 10 blocks the cold air as it passes through the aluminum outer frame 1 and inner frame 2, transferring the temperature downwards. The heat insulation structure slows down the temperature transfer, allowing it to enter the thermal break of the outer frame 1, making it difficult for cold air to transfer from outside to inside the window. Furthermore, when the inner frame 2 moves the glass 3, the heat insulation structure supports the inner frame 2, preventing the heat insulation strip 10 from bursting and damaging the outer frame 1. The heat insulation structure also better blocks the gap between the inner frame 2 and the outer frame 1, resulting in better heat insulation performance.

[0036] Reference Figure 2 and Figure 3 , Figure 5 The thermal insulation structure includes a thermal insulation layer 7 formed inside the outer frame 1. A sliding strip 12 is fixedly connected inside the outer frame 1, and the lower end of the sliding strip 12 is in contact with the thermal insulation strip 10. A fixing strip 14 is fixedly connected to the upper end of the outer frame 1, and an abutment strip 15 is slidably connected to the upper end of the outer frame 1. Guide strips 19 are fixedly connected to the upper ends of both the fixing strip 14 and the abutment strip 15. A guide groove is formed at the lower end of the inner frame 2, and the shape of the guide groove is adapted to the guide strip 19. An inclined strip 13 is fixedly connected to one side of the sliding strip 12, and a moving strip 16 is fixedly connected to the lower end of the inner frame 2. An inclined groove is formed inside the moving strip 16, and the shape of the inclined groove is adapted to the inclined strip 13. Diamond-shaped limiting strips 11 are fixedly connected to both ends of the thermal insulation strip 10, and the diamond-shaped limiting strips 11 are slidably connected to the outer frame 1. A lifting spring 17 is fixedly connected inside the outer frame 1, and the upper end of the lifting spring 17 is fixedly connected to the abutment strip 15. The outer frame 1 has a guide bar 18 fixedly connected inside, and the guide bar 18 is slidably connected to the abutment bar 15.

[0037] When the cold air flows through the aluminum outer frame 1 and inner frame 2, it first contacts the sliding strip 12 and moves towards the thermal insulation strip 10. The thermal insulation strip 10 then blocks the cold air, conducting the heat downwards to the connecting strip 8. The thermal insulation layers 7 on both sides further slow down the heat transfer, allowing it to enter the thermal break of the outer frame 1, preventing cold air from easily transferring from outside to inside the window. When the inner frame 2 moves the glass 3, the sliding strip 12 at the lower end of the inner frame 2 moves in conjunction with the moving strip 16. Simultaneously, one end of the inner frame 2 is guided by the guide strip 19. The movement is more stable. At the same time, the two sides of the inner frame 2 are resisted and supported by the abutment strip 15 and the fixing strip 14 respectively. As the lifting spring 17 continues to push the abutment strip 15 upward, the abutment strip 15 will always push the inner frame 2 upward, so that the abutment strip 15 moves along the guide strip 18 to make its support of the inner frame 2 more stable. At the same time, the tilting strip 13 will move in the tilting groove and fill the gap between the abutment strip 15 and the inner frame 2, so that the heat insulation strip 10 is less likely to burst and cause damage to the outer frame 1. It can also better block the gap between the inner frame 2 and the outer frame 1, so that the heat insulation effect of the device is better.

[0038] Reference Figure 2 and Figure 3 , Figure 4 An installation strip 4 is slidably mounted on the outer surface of the outer frame 1. One side of the installation strip 4 abuts against the inner frame 2. A bolt 5 is threadedly connected to one end of the installation strip 4, and the bolt 5 is threadedly connected to the outer frame 1. A filler sleeve 6, which is a flexible rubber sleeve, is slidably connected to the outer surface of the installation strip 4. A sliding post 20 is fixedly connected inside the filler sleeve 6, and the end of the sliding post 20 is fixedly connected to the installation strip 4. An abutment spring 21 is fixedly connected inside the installation strip 4, and the end of the abutment spring 21 is fixedly connected to the flexible rubber sleeve.

[0039] When installing the inner frame 2, first rotate the bolt 5 so that its end is no longer connected to the outer frame 1. Then remove the mounting strip 4 to leave more installation space on one side of the outer frame 1. Next, install the inner frame 2 inside the outer frame 1. After installing the inner frame 2, attach the mounting strip 4 to the inner frame 2 and rotate the bolt 5 to fix the mounting strip 4 to the outer frame 1. As the mounting strip 4 moves towards the inner frame 2, the filling sleeve 6 is squeezed by the inner frame 2 and the fixing strip 14, causing the contact spring 21 to extend and retract. As the spring returns to its original position, it pushes the filling sleeve 6 to fill the gap between the inner frame 2 and the fixing strip 14. The filling sleeve 6 moves along the sliding column 20 towards the gap, making the filling of the gap more compact. This makes it easier to install the inner frame 2 and the outer frame 1 and further improves the thermal insulation effect of the device.

[0040] Working principle: When cold air flows through the aluminum outer frame 1 and inner frame 2, it first contacts the sliding strip 12 and moves towards the thermal insulation strip 10. The thermal insulation strip 10 then blocks the cold air, isolating it at the connecting strip 8. The thermal insulation layers 7 on both sides further slow down the heat transfer, allowing it to enter the thermal break of the outer frame 1, preventing cold air from easily transferring from outside to inside the window. When the inner frame 2 moves the glass 3, the sliding strip 12 at the lower end of the inner frame 2 moves in conjunction with the moving strip 16. Simultaneously, one end of the inner frame 2 is guided by the guide strip 19, making its movement more precise. The inner frame 2 is stabilized, and its two sides are supported and supported by the abutment strip 15 and the fixing strip 14 respectively. As the lifting spring 17 continues to push the abutment strip 15 upward, the abutment strip 15 will always push the inner frame 2 upward, so that the abutment strip 15 moves along the guide strip 18 to make its support of the inner frame 2 more stable. At the same time, the tilting strip 13 will move in the tilting groove and fill the gap between the abutment strip 15 and the inner frame 2, so that the heat insulation strip 10 is less likely to burst and cause damage to the outer frame 1, and can better block the gap between the inner frame 2 and the outer frame 1, so that the heat insulation effect of the device is better.

[0041] When installing the inner frame 2, first rotate the bolt 5 so that its end is no longer connected to the outer frame 1. Then remove the mounting strip 4 to leave more installation space on one side of the outer frame 1. Next, install the inner frame 2 inside the outer frame 1. After installing the inner frame 2, attach the mounting strip 4 to the inner frame 2 and rotate the bolt 5 to fix the mounting strip 4 to the outer frame 1. As the mounting strip 4 moves towards the inner frame 2, the filling sleeve 6 is squeezed by the inner frame 2 and the fixing strip 14, causing the contact spring 21 to extend and retract. As the spring returns to its original position, it pushes the filling sleeve 6 to fill the gap between the inner frame 2 and the fixing strip 14. The filling sleeve 6 moves along the sliding column 20 towards the gap, making the filling of the gap more compact. This makes it easier to install the inner frame 2 and the outer frame 1 and further improves the thermal insulation effect of the device.
