AI Technical Summary

Technical Problem

Traditional sliding door dampers are inconvenient to install and remove, cannot automatically adjust the angle, and do not have a self-lubricating function, resulting in poor sliding or jamming. Furthermore, it is difficult to combine split-type hanging wheels with self-balancing hanging wheels.

Method used

A split-type self-balancing sliding door hanging pulley was designed, which adopts a structure of middle seat, wheel assembly and positioning screw, and achieves automatic positioning by combining magnetic adsorption and positioning groove. It is equipped with a lubrication box for automatic lubrication, and the roller angle is adjustable.

Benefits of technology

It achieves automatic positioning and lubrication of the wheelset, simplifies the assembly process, and combines a split and self-balancing structure to ensure smooth sliding and adjustable angle, improving ease of use and reliability.
