AI Technical Summary

Technical Problem

The existing slide rail press-and-rebound mechanism is prone to deviating from the normal movement trajectory during energy storage, leading to failure. In addition, the protruding edge setting causes shaking and jamming, resulting in poor stability.

Method used

An elastic anti-fall component is added to the energy release groove. Through the linkage of the elastic deformation part and the stop part, the rotating hanging part is ensured to slide along the normal movement trajectory, avoiding reverse falling. Combined with sound-absorbing soft rubber, the stability is improved.

Benefits of technology

It effectively prevents the failure of the press-and-rebound mechanism, ensures the drawer closes and opens normally, improves operational stability and reliability, and reduces noise through sound-absorbing soft rubber.
