Small size inlay hinge

By using a small-sized embedded hinge design, stress is dispersed through connecting frames, support cylinders, and X-shaped support frames. Combined with lubrication and sealing measures, the problem of local deformation of the sub-hinge under axial load is solved, improving the stability and lifespan of the hinge.

AI Technical Summary

Technical Problem

In the prior art, when the sub-hinge is subjected to axial load, the mechanical stress cannot be effectively dispersed, which makes the second sleeve prone to bending and deformation.

Method used

It adopts a small-sized embedded hinge design, and through the cooperation of the connecting frame, support cylinder and X-shaped support frame, it uses the triangular truss principle to disperse stress, and uses oil storage tank and lubricating oil to lubricate the central shaft to reduce dry friction. It uses support bearing to convert sliding friction into rolling friction, increases sealing performance, and uses the receiving groove to share the force.

Benefits of technology

It effectively prevents bending and torsional deformation of the sub-hinge and connecting cylinder, improves the stability and lifespan of the mother hinge and sub-hinge, reduces wear, and enhances sealing and installation stability.

Abstract

The utility model relates to the field of hinge discloses a small size embedded hinge, including two sleeves, two sleeve all weld in the right side of female hinge, the inner wall of sleeve inserts with central axis, the right side of female hinge sets up sub hinge, the left side of sub hinge is welded with a plurality of connecting barrels, the connecting barrel corresponds with sleeve, the connecting barrel is equipped in the outer wall of central axis, two connecting frames are welded on the sub hinge, one end of connecting frame is welded with support cylinder, the support cylinder corresponds with connecting barrel, the support cylinder is equipped in the outer wall of central axis, in the utility model, through the cooperation of connecting frame, support cylinder and X-shaped support frame, can disperse stress through the principle of triangular truss when sub hinge bears axial load, forms multidirectional constraint when sub hinge is loaded, effectively prevents the bending and torsional deformation of sub hinge and connecting barrel under stress, and simultaneously spreads local stress to the whole of connecting frame.
