The spring hinge that used the frame of a pair of spectacles

摘要

The present invention relates to eyeglass frames spring hinge, the bottom surface of the conventional spring hinge to occur as the resistance welding is formed with a joint projection of the four places of the adhesion of the melted joining protrusion but to be bonded while the said resistance projection melt by resistance heat the weak to solve the problems such as that might leak out into working joints simple, clean work orders and triangular feldspar which is fixed to the to the spectacle frame developed to so as to have a high bonding strength with the triangular feldspar and hinged to combine in the connector, a conventional spring hinge for spectacle frame to form a housing that is fixed to the temple connector that is involved to the spring action in the housing;; The triangular feldspar first engagement projection formed on the bottom in the center, composed of parts of a first groove formed on the rim adjacent to the outer surface of the bottom surface;; The housing also relates to a spring hinge for spectacle frames, characterized by yirueojim portion a second groove formed on the rim adjacent to the second engagement projections, the outer surface of the bottom surface of the two portions are formed at a predetermined interval on the bottom surface center.
