Description

Technical Field

[0001] The utility model relates to the technical field of eyeglass frame production, in particular to a wear-resistant eyeglass frame testing device. Background Art

[0002] The eyeglass frame is an important part of glasses, mainly playing the role of supporting the spectacle lenses, and a beautiful-looking eyeglass frame can also play a role in beautification. The materials mainly include metal, plastic or resin, natural materials, etc. According to the style, it can be divided into full-frame, semi-frame, frameless and other types. The eyeglass frame needs to use a wire tensile strength testing device to test the tensile strength of the wire.

[0003] For example, the authorized announcement number "CN114323948B" is a wire tensile strength testing device for eyeglass frames and its usage method. Although through the set fixing component, the wire for the eyeglass frame to be detected is clamped and fixed between the clamping plate with positioning teeth and the tooth groove, and the first positioning plate and the second positioning plate are connected to each other to fix and clamp the wire for the eyeglass frame to prevent it from slipping during the test. At the same time, a groove body is arranged on one side of the first positioning plate and the second positioning plate, and when detecting, the protruding side of the wire for the eyeglass frame is placed inside to increase the stability of the detection of the wire for the eyeglass frame.
