Portable folding glasses

Abstract

The invention relates to portable folding glasses. The portable folding glasses comprise a pair of glasses frames, lenses and a pair of glasses feet, a first connector is hinged between the glasses frames horizontally, and each glasses foot comprises a front section and a rear section which are hinged through a second hinge shaft which is vertically arranged. Second positioning notches and elasticretractable push blocks are respectively arranged on the first connector and the glasses frames, the push blocks are elastically abutted in the corresponding second positioning notches or second positioning pits under the folding state of the glasses, and the glasses frames can be sustained in the folding state; in addition, the front sections and the rear sections of the glasses feet are partially overlapped, third hinge shafts used for hinging the front sections and the rear sections are arranged in the overlapping parts, contact surfaces of rear ends of the front sections and front ends ofthe rear sections are always contacted with each other through the third hinge shafts, the front sections and the rear sections of the glasses feet can be sustained in the folding state through friction force between the contact surfaces of the front sections and the rear sections, and problems existing in existing folding glasses are solved.

Description

technical field [0001] The invention relates to spectacles, in particular to portable foldable spectacles which are easy to carry and not easy to damage the lenses. Background technique [0002] Due to congenital reasons, unhygienic use of the acquired eyes and the growth of age, the refractive system of the eyes cannot focus the external objects on the retina well, resulting in blurred vision. For this reason, they need to wear glasses for correction. Therefore, glasses are an inseparable reading aid that many people often use in their daily lives. Glasses generally include a frame, a beam, a nose pad, mirror feet and a pile head hinge mechanism. But the existing glasses are bulky and inconvenient to carry because the frames and feet cannot be folded or stretched. In order to solve the problem of portability, people subsequently developed foldable portable glasses. For example, the publication number is CN102262304, and the publication date is 2011.11.30. The middle and ...

AI Technical Summary

Problems solved by technology

However, due to defects in the hinged structure of the existing portable folding glasses, they cannot be well kept in the folded state after being folded, such as the front section and the rear section of the mirror feet and the loose opening between the two frames, which affects carrying
