AI Technical Summary

Technical Problem

Existing sliding door glass panels are prone to wobbling and instability during the sliding process. After a period of use, they get stuck in the guide rails, causing the sliding to become uneven and easily worn, posing a safety hazard.

Method used

The door uses insulated glass panels. The bottom of the inner frame is equipped with pulleys that support the U-shaped guide rail. The arc grooves of the pulleys match the convex arc surface of the guide rail. The top two sides are equipped with lining strips, and the bottom is equipped with soft pads and nylon strips. Multiple layers of glass are movable and clamped inside the outer frame to limit the swing of the door panels.

Benefits of technology

It effectively prevents door swaying, improves the stability of pushing and pulling, extends service life, and ensures safety and smooth operation.
