AI Technical Summary
Technical Problem
During the installation of aluminum alloy doors and windows, the pulleys are prone to falling off the slots due to impact or excessive pulling force, causing the doors and windows to derail, affecting the stability of use and causing noise problems.
Method used
The guide rail body adopts a fixed frame and damping spring structure. The damping spring compression absorbs the impact force and ensures that the rollers are in close contact with the inner wall of the slide. Combined with the limit slider and sealing strip design, it prevents derailment and noise generation.
Benefits of technology
It effectively prevents doors and windows from derailing, reduces noise, improves stability and smoothness of use, and enhances impact resistance.

Abstract
This application relates to the field of aluminum alloy door and window technology, and discloses an anti-derailment structure for aluminum alloy doors and windows, including a guide rail body. The guide rail body has an internal mounting cavity, and a through-groove is formed in the center of the mounting cavity. A fixed frame is installed inside the mounting cavity, and two sets of first sliding grooves are symmetrically formed on both side walls. A glass door is installed inside the fixed frame, with one end of the glass door extending through the groove to the outside of the guide rail body. Two sets of sleeves are symmetrically installed on both sides of the fixed frame. A connecting shaft is slidably installed inside the sleeve at the end away from the fixed frame. One end of the connecting shaft is fixed to the inner wall of the sleeve with a damping spring, and the other end extends into the first sliding groove where a first roller is installed. Because the width of the fixed frame is greater than the width of the outer through-groove, it will not detach from the guide rail body. Since the first roller is always in close contact with the inner wall of the first sliding groove, it will not generate significant noise.
