AI Technical Summary
Existing two-way hinges have a problem with mismatched hole spacing in the design, manufacturing and installation stages, resulting in uneven installation, causing safety hazards such as loose screws, component wear and door jamming, affecting traffic efficiency and user experience.
The device employs a toothed plate and toothed block meshing structure. The height of the mounting bolts is adjusted by sliding the toothed plate up and down inside the mounting bracket. This, together with the limiting plate and sealing plate, forms a double sealing structure, ensuring that the mounting bolts are aligned with the external holes and form a rigid lock, preventing uneven force distribution and insufficient sealing performance.
It effectively compensates for hole position deviations, improves installation stability and sealing, reduces screw loosening and component wear, ensures smooth operation of the bidirectional opening and closing function, reduces safety hazards, and extends service life.
