Description

Technical Field

[0001] This utility model relates to the technical field of anti-derailment devices combining flat mesh and plastic steel, specifically anti-derailment devices combining flat mesh and plastic steel. Background Technology

[0002] Sliding windows offer advantages such as not taking up interior space, attractive appearance, economical price, and good sealing. They utilize high-grade sliding tracks, allowing for smooth and easy opening with a gentle push. Combined with large panes of glass, they increase indoor lighting and improve the overall appearance of the building. The window sashes have good structural integrity and are not easily damaged, but their ventilation area is somewhat limited.

[0003] Existing folding sliding windows use stainless steel for their bottom anti-derailment fittings. Stainless steel is expensive to manufacture, and folding sliding windows are noisy when sliding and folding. Therefore, we invented a flat mesh and plastic steel combined anti-derailment device.
