Fixing device of glasses lens

Abstract

The invention discloses a fixing device of a glasses lens, which comprises a lens and a drawn wire, wherein a drawn wire groove is formed in the lens; a drawn wire supporting rack is arranged in the drawn wire groove, and comprises a positioning inserter and an arc supporting piece which are matched with the drawn wire groove; the inner end of the arc supporting piece and the outer end of the positioning inserter are integrally arranged; a limiting groove is formed in the middle of the outer end of the arc supporting piece, and is a semicircular groove; the drawn wire is arranged in the limiting groove in an embedded manner; and the drawn wire supporting rack is compressed on the lens by tightening the drawn wire. With the adoption of the technical scheme, the fixing device is reasonable in structural design, simple in structure, convenient to mount and dismount, reliable in fixation, high in mounting efficiency and good in practicability; and the possibility of lens rupture is low.

Description

technical field [0001] The invention relates to the technical field of spectacles, in particular to a spectacle lens fixing device. Background technique [0002] At present, fashionable, light, elegant non-drilling type rimless glasses or half-rim glasses are favored by consumers, and non-drilling type rimless glasses or half-rim glasses have become an important part of the glasses fitting market. The unique charm of rimless glasses or half-rim glasses, personalized lens shape, simple design, and high-grade materials have attracted the attention of many consumers; however, non-drilled rimless glasses or half-rim glasses still have shortcomings: production standards Not uniform, the assembly process is immature, the lens groove is not standard, which affects the levelness, and is easy to cause fragments; especially for some relatively thin lenses, the groove is very difficult, easy to break, the installation efficiency is low, and the wire drawing cannot be used Thick ones c...
