Abstract
This utility model relates to the technical field of sliding door accessories, specifically a sliding door anti-sway device. It includes a base plate and rollers mounted on the base plate. A horizontally arranged swing arm is mounted on the base plate via a pivot located in the middle of the swing arm. Both ends of the swing arm have longitudinally arranged axles, on which a first roller and a second roller are respectively mounted. A torsion spring is fitted onto the pivot to drive the swing arm to rotate. The first and second rollers of this anti-sway device are respectively in close contact with the side walls of the groove at the lower end of the door leaf, eliminating any swing clearance at the lower end of the door leaf, thus reducing noise during door sliding and improving the user experience.
