Description

TECHNICAL FIELD The present invention belongs to the technical field of eyeglasses, and specifically is an improved double-rim eyeglass with multiple benefits.

Glasses are used to improve vision, protect the eyes, and for decorative purposes, and they can correct various vision problems such as nearsightedness, farsightedness, astigmatism, presbyopia, strabismus, and amblyopia.
Glasses consist of lenses and frames.
Depending on the role of the glasses, there are nearsighted glasses, farsighted glasses, presbyopic glasses/astigmatic glasses, plano glasses, computer goggles, goggles, swimming goggles, night vision goggles, gaming goggles, wind goggles, sunglasses, black glasses, Divided into toy glasses and sunglasses.
Conventional eyeglasses usually have a nose pad in the middle of the lens, and tip cells on the left and right arms where they touch the ears.

The double-rim glasses with multiple effects in the existing Chinese Patent Document Disclosure No. CN216979463U are supported by the first nose pad through the hanging part of the second nose pad, and then the first hinge and the second endpiece are connected to the first magnet. The connection is made quickly by the adsorption action of the second magnet, and the overall connection structure is simple and assembly is quick.

However, in the process of realizing the above technical proposal, it was found that the above technical proposal had the following technical problems.

The magnet in the conventional first rim endpiece is fitted inside the endpiece from the top to the bottom, and after being attracted to the magnet at the bottom of the second rim endpiece, the second frame and first frame are connected and fixed. However, when the magnet fitted in the bottom endpiece is attracted to the top magnet, the two magnets can loosen in the groove and move closer to each other, so the second frame can move closer to the first frame. A situation where the second rim is easily lost because it separates from the top is likely to occur.
