Embodiment Construction
[0037] A metal spectacle frame, such as figure 1 with figure 2 As shown, it includes a spectacle frame 1, a nose pad and temples 2 arranged on both sides of the spectacle frame 1. Wherein, the mirror frame 1 includes a steel skin 11, and the steel skin 11 has two frame holes for installing lenses, and the interference fit in the two frame holes is a loop wire 12 that is closely attached to the inner wall of the frame hole, and the loop wire 12 The two opposite sides protrude from the two opposite sides of the steel skin 11, and the side walls of the two loop wires 12 away from the temple 2 are fixedly connected with anti-deformation strips 13, and a middle beam 14 is welded between the two anti-deformation strips 13. A copper wire is wound on the picture frame 1, and the copper wire passes through the frame hole and wraps the steel skin 11, the ring wire 12, the anti-deformation strip 13 and the frame hole to make it integrated, so as to improve the flatness of the outside o...

The invention discloses a metal spectacle frame which comprises a spectacle frame, a nose pad and spectacle legs. The spectacle frame comprises sheet iron, the sheet iron runs through two frame holesfor lens installation, coils are in interference fit with the interior of the two frame holes, the two sides of the coils protrude out of the two sides of the sheet iron, anti-deformation strips are arranged on the side walls, away from the spectacle legs, of the two coils, and a middle beam is welded between the two anti-deformation strips. The coils are in interference fit with the frame holes,the frame holes can be opened, the sheet iron deformation amount is lowered, and the structural strength of the spectacle frame is improved; by arranging the anti-deformation strips, spatial obstruction can be performed on the sheet iron when the sheet iron is bent so as to stop the sheet iron from further deforming, the stability and the structural strength of the spectacle frame are further improved, the two opposite sides of the coils protrude out of the two opposite sides of the sheet iron so that the deformation space can be provided for the sheet iron, and the flexibility of the spectacle frame is improved; by arranging the middle beam, the two anti-deformation strips are fixed, and the structure strength and stability of the spectacle frame are improved while the sheet iron is prevented from deforming.
Description
technical field [0001] The present invention relates to a spectacle frame, more particularly to a metal spectacle frame and a preparation method thereof. Background technique [0002] The spectacle frame is an important part of the glasses, and the most important thing is to support the spectacle lenses. A pair of spectacle frames is usually composed of main parts such as mirror rings, nose pads, pile heads and temples. In addition to the above components, there are foot covers, stipule screws, hinge screws, etc. Among them, the main materials of glasses are metal, plastic or resin, natural materials, etc., and can be divided into full frame, plate frame, frameless and other types according to the style. Among them, the metal spectacle frame has the characteristics of firmness, beauty, good wear resistance and long service life. [0003] The Chinese patent with the notification number CN101414061B discloses a manufacturing method of a spectacle frame, which includes a spec...
