Spherical-hinge-type glasses nose pad component convenient to mount and demount

Abstract

The invention relates to a spherical-hinge-type glasses nose pad component convenient to mount and demount. The spherical-hinge-type glasses nose pad component comprises a tobacco pipe and a tobacco leaf, a spherical protrusion is arranged at the end of the tobacco pipe, a spherical socket seat is arranged on the tobacco leaf, a spherical socket cavity holding the spherical protrusion and an embedding port allowing the spherical protrusion to be embedded in the spherical socket cavity are arranged on the spherical socket seat, the spherical protrusion on the tobacco pipe is in movable fit in the spherical socket cavity of the spherical socket seat, the spherical socket seat is provided with a limiting opening groove in a laterally through manner, an opening of the limiting opening groove is correspondingly communicated with the embedding port, an arm rod of the tobacco pipe is embedded in the limiting opening groove in a positioned manner and is in limiting fit with limiting walls on two sides and a bottom wall of the limiting opening groove, a stopping protrusion higher than a spherical surface is arranged on the spherical protrusion, a blade swing adjusting space for the stopping protrusion to move in is formed on the spherical socket seat, and the edge of the blade swing adjusting space is provided with a stopping wall in stopping fit with the stopping protrusion. The spherical-hinge-type glasses nose pad component has the advantages of being reasonable in structural design, simple and compact, convenient to wear, mount and demount.

Description

technical field [0001] The invention relates to glasses accessories, in particular to a glasses nose pad assembly. Background technique [0002] Nose pads (called leaves or tobacco leaves in the industry) are all installed on the existing spectacle frames, and the nose pads are usually connected with one end of the pipe by screws, and the other end of the pipe is fixed on the spectacle frame. This kind of structure needs dismounting screws when installing and changing the nose pads, which is inconvenient to operate and cannot be manually operated without tools; and because the nose pads are small in size, it is inconvenient to operate. [0003] In order to solve the above problems, the existing tobacco leaf and pipe are connected by a ball hinge, omitting screw operation, the installation and disassembly of the tobacco leaf is convenient, and the multi-dimensional rotation of the tobacco leaf within a certain angle range is achieved, which better adapts to the bridge of the ...

AI Technical Summary

Problems solved by technology

However, the tobacco leaves can be rotated in the circumferential direction. When wearing them, the tobacco leaves are turned over, and its edge touches the bridge of the nose. It needs to be straightened in advance, which brings inconvenience to the wearing. The tobacco leaves are easy to be reversed during assembly, which brings inconvenience to the assembly; The mouth of the pipe-shaped groove for the spherical protrusion on the pipe is also the mouth for the pipe to protrude. During assembly, due to the obstruction of the arm bar of the pipe, only the tobacco leaves can be pushed for assembly operation, which is inconvenient to assemble. Rod bending hazard
