Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy doors and windows, and particularly relates to a novel assembled aluminum alloy door and window structure. Background Art

[0002] Aluminum alloy doors and windows are door and window products made of aluminum alloy extrusion profiles as frames, mullions and sash materials. According to different opening methods, aluminum alloy doors and windows can be mainly divided into various types such as casement type, sliding type and folding type. Among them, a pulley group device is usually equipped at the lower end of the sliding aluminum alloy doors and windows to ensure the smoothness of the door and window sliding process.

[0003] According to an assembled aluminum alloy door and window disclosed in the application number: CN202420851486.9, which includes a door and window assembly. Two sliding grooves are opened at both inner ends of the door and window assembly. Two sliding rails are arranged in the sliding grooves. A first sliding door frame and a second sliding door frame are respectively slidably connected to the two sliding rails. Connecting plates are embedded at the bottoms of the first sliding door frame and the second sliding door frame, and a cleaning brush is fixedly connected to the bottom of the connecting plate. Four storage boxes are symmetrically installed at the bottom of the outer side of the door and window assembly. One end of each storage box penetrates through the door and window assembly and communicates with the sliding groove. The utility model can clean a certain amount of dust in the sliding groove of the assembled aluminum alloy door and window, and the cleaning effect can be completed only when the door and window is usually used. At the same time, the dust is directly cleaned and accumulated into the storage box, which not only improves the cleaning effect, but also improves the cleaning convenience and reduces the cost of manual cleaning.

[0004] However, during the use of the existing assembled aluminum alloy doors and windows, with the passage of time, the pulley assembly will inevitably be affected by environmental factors, resulting in a decline in sliding performance. The traditional installation method is to directly fix the pulley on the door and window frame. When the pulley needs to be replaced, usually the entire aluminum alloy door and window needs to be disassembled first before the pulley replacement operation can be carried out. The operation process is cumbersome and affects the maintenance efficiency. Summary of the Invention

By pressing the hinged rods on both sides of the lower end of the sliding door, the limit block is driven to disengage from the limit groove, and the installation baffle can be removed. By pulling the pulley rod to disengage the fixing hole from the fixing pin, the pulley rod can be replaced. During installation, the new pulley rod is connected to the fixing pin through the fixing hole, and the installation baffle is reinstalled to make the fixed block slide into the connecting groove. The limit block is stuck in the limit groove under the action of the reset torsion spring, thereby completing the fixation of the pulley rod and the installation baffle. The operation is simple, which further improves work efficiency and reduces labor intensity.

[0017] In addition, the protective mechanism is provided to prevent the sliding door 4 from pinching the user's hands. If the sliding rubber block encounters resistance during the door closing process, it will slide into the door body under the action of the fixed spring to avoid pinching, thereby significantly improving the safety of use.
