Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane doors and windows, in particular to a composite frame for polyurethane doors and windows. Background Art

[0002] Door and window frames are the most basic and important part of the door and window structure. They are usually made of metal materials or high-strength alloys to ensure the stability and durability of doors and windows. Door and window frames are made of a variety of materials, including aluminum alloy, plastic steel, wood, thermally-insulated aluminum, etc. The frame structure usually includes the frames, crossbeams and longitudinal beams of doors and windows. These components are closely connected to form an integral structure, which provides basic support and protection for doors and windows. In general, door and window frames are an indispensable part of the door and window system. Their materials, structures, functions and designs will directly affect the performance and use of doors and windows.

[0003] For example, the Chinese patent "Aluminum Alloy Composite Door and Window Frame" with announcement number CN208089111U includes an inner frame, an outer frame and an insulation component assembled between the two, the insulation component includes a male insulation strip and a female insulation strip, both insulation strips are integral parts, including an insulation body at the bottom and a plurality of insulation arms arranged on one side of the insulation body, a plurality of independent cavities are provided in the middle of the insulation body, and profile clamps for connecting with the inner frame and the outer frame are provided at both ends, the two insulation strips are arranged with their insulation arm sides facing each other, and the area between the inner frame and the outer frame is divided into a plurality of insulation cavities by the insulation arms, the outer side of the inner frame and the inner side of the outer frame are provided with a pair of strip clamps, the two insulation strips are respectively inserted into the strip clamps with the profile clamps at both ends, and the length of the insulation arm is greater than half of the distance between the pair of strip clamps.

[0004] Although the above-mentioned prior art can realize the installation and use of door and window frames, in actual use, on the one hand, the stability of the doors and windows when moving on the frames is not good enough. When the doors and windows are moving, the doors and windows on both sides move in a slide groove, which leads to a reduction in the support points of the doors and windows, thereby reducing the stability of the doors and windows. On the other hand, the accumulated water in the frame is difficult to drain. After rainfall, the rainwater will be retained in the slide groove, resulting in the rainwater soaking the slide groove for a long time, causing the frame to deform, thereby shortening the service life of the frame. Therefore, it does not meet the existing needs. In this regard, we propose a composite frame for polyurethane doors and windows. Utility Model Content
