A connector for flip type front hanging glasses and front hanging glasses

Abstract

The invention discloses a connector of a pair of turnover front glasses and the pair of front glasses, belonging to the field of external glasses. According to the connector, a first magnetic region is arranged in the middle of the bottom surface of the connector; two pins are arranged on two sides of the bottom surface of the connector; two vertical columns are arranged on two sides of the upper part of the connector; a rotary shaft is arranged between the two vertical columns and has a regular polygonal cross section; the connector is in an integrated structure. According to the front glasses, main glasses comprise a main glasses frame, main lenses, glasses legs and nose pads; auxiliary glasses comprise an auxiliary glasses frame and auxiliary lenses; pin holes corresponding to the pins are formed in the nose pads of the main glasses frame; a second magnetic region attracting the first magnetic region is arranged between the pin holes; a clamping piece groove matched with the rotary shaft is formed in the auxiliary glasses frame; a rotary shaft clamping groove for containing the rotary shaft is formed in the clamping piece groove. According to the connector and the front glasses, the structural design of the main glasses cannot be influenced, the main glasses and the auxiliary glasses are reliable to connect and convenient to dismount, the auxiliary glasses are simple in structure and can overturn at different angles, and the problem of excessive tightening or loosening in an assembling process is solved.

Description

technical field [0001] The invention relates to a connector for hanging glasses on the front and the glasses on the front, more specifically, to a connecting piece for hanging glasses on the front and a flip-type connecting piece for hanging glasses on the front. Background technique [0002] People with poor eyesight such as myopia and hyperopia usually use ordinary optical glasses to ensure vision, as well as sunglasses and polarizers to prevent ultraviolet rays and strong light from being irradiated. At present, there are also double-layer glasses on the market, and the use of this kind of glasses is becoming more and more extensive. The double-layer glasses are composed of a main mirror and a secondary mirror, which can realize the dual function of myopia or hyperopia and sunglasses or polarizers on a pair of glasses. Function, after most of these glasses are installed, the main mirror and the secondary mirror are relatively fixed, and the secondary mirror can only be di...

Problems solved by technology

The installation and disassembly of the sleeve mirror in this application is quick and easy, and the bottom mirror only needs to be slightly changed without affecting the overall appearance of the bottom mirror. , there is also the problem that the fit is too tight or too loose; in addition, the bayonet of the nose bridge and the chute of the nose bridge are clamped in the horizontal direction. The bayonet of the frame moves relative to the chute of the nose bridge, or even disengages, causing unnecessary troubles
