Automatically-opened elastic earpiece

Abstract

The invention discloses an automatically-opened elastic earpiece which comprises a front hinge head and an earpiece body, wherein the front hinge head is movably connected with the earpiece body; an inner hole is formed in the earpiece body; a long spring and a piston are sequentially arranged in the inner hole from inside to outside; one end of the piston is connected with the long spring in a leaning way, and the other end of the piston is an arc-shaped end and is connected with the front hinge head in a leaning way; the surface, connected with the piston in a leaning way, of the front hinge head is an arc-shaped surface protruding towards the earpiece body. A through hole is formed in the front hinge head; a screw hole is formed in the earpiece body; the front hinge head and the earpiece body are movably connected with each other by enabling a screw to pass through the through hole and the screw hole; a counter bore is formed at the side close to the head of the screw, of the front hinge head; a short spring is arranged in the counter bore; the short spring is compressed between the head of the screw and the front hinge head. According to the automatically-opened elastic earpiece, the effect of automatically opening is achieved by carrying out action on a circular arc by the force transmitted by using the long spring to act on the piston; the automatically-opened elastic earpiece is simple in assembly and practical; due to the action of the short spring, the opening speed can be freely adjusted.

Description

technical field [0001] The invention belongs to the technical field of spectacles, and in particular relates to an elastic spectacle foot with an automatic opening function. Background technique [0002] Glasses are usually composed of spectacle frames, spectacle temples and spectacle lenses, which have the function of correcting vision or protecting eyes. With the rise of the number of myopia and the popularity of various decorative glasses, glasses have become more and more necessary for people's life. The requirements for aesthetics, convenience and wearing comfort are also getting higher and higher. [0003] Spectacles on the existing market are generally connected by hinge screws between the spectacle frame and the spectacle legs. Spectacle feet are generally rod-shaped, mostly made of plastic materials, metal materials or plate materials, and the function of the glasses feet is generally to cooperate with the nose pads to fix the glasses. [0004] With the current sp...

Problems solved by technology

[0004] With the current spectacle temple structure, in the normal process of wearing glasses, the user must first open the left and right temples by hand before wearing them. When taking off the glasses, it is also necessary to artificially close the temples first Only then can the glasses be put into the glasses case. This operation method makes the opening and closing of the glasses cumbersome and inconvenient

Especially when the user is operating other actions and cannot free his hands to open the temples, the use of glasses becomes very inconvenient
