Description

Technical Field

[0001] This utility model relates to the field of door and window frame technology, specifically to a heat-insulating aluminum alloy door and window frame. Background Technology

[0002] In the construction industry, doors and windows, as an important component of buildings, not only fulfill basic functions such as ventilation and lighting, but also have a crucial impact on the building's thermal insulation performance. With the improvement of people's living standards and the increasing prominence of energy issues, the requirements for the thermal insulation performance of doors and windows are also becoming increasingly stringent. While traditional aluminum alloy door and window frames have advantages such as light weight, high strength, and corrosion resistance, they have certain shortcomings in terms of thermal insulation performance.

[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: The sealing method of existing aluminum alloy door and window frames typically relies on the simple contact and compression between the sealing strip and the door / window frame. However, during use, because the contact pressure between the sealing strip and the door / window frame is difficult to control precisely, as the doors and windows are used for a longer period, the sealing strip may age or deform, leading to reduced contact pressure and a poorer sealing effect. This allows indoor and outdoor air to exchange through the gaps in the doors and windows, causing heat loss and affecting the building's thermal insulation performance.

[0004] Therefore, we propose an insulated aluminum alloy door and window frame that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a heat-insulating aluminum alloy door and window frame, which solves the problems mentioned in the background art.

The groove 2 and the connecting frame 21 are inverted U-shaped and are horizontally placed inside the groove 2. An adjusting rod 22 is horizontally fixedly installed in the middle of the connecting frame 21. The end of the adjusting rod 22 away from the connecting frame 21 passes through the groove 2 and is fixedly connected to the middle of the adjusting plate 15. The two ends of the connecting frame 21 are respectively fixedly connected to two sets of first wedge blocks 24. The two sets of first wedge blocks 24 are symmetrically arranged. A fixing rod 26 is horizontally fixedly installed in the middle of the side of the sealing strip 14 away from the slide groove 11. The end of the fixing rod 26 away from the sealing strip 14 passes through the inner wall of the groove 2 and is fixedly installed with a second wedge block 25. The first wedge block 24 and the second wedge block 25 are slidably connected, and the dimensions of the first wedge block 24 and the second wedge block 25 are matched.

[0019] In this technical solution, the sliding connection between the slide groove 11 and the door / window frame 12 allows the door / window frame 12 to move left and right, facilitating the opening and closing of the door / window.
