CN2233094Y - Improved Mirror Frame Bridge - Google Patents

Abstract

The utility model relates to an improved eyeglass frame bridge structure, which mainly utilizes an insert made of white copper for the bridge end pins connecting the eyeglass frame to extend into. Afterwards, the insert and the bridge end pins are first made of white copper for welding, and then the insert and the eyeglass frame made of the same white copper material are welded together, thereby improving the conventional method of directly welding the bridge to the eyeglass frame, because the bridge and the eyeglass frame are made of different materials and have different melting points, so that it is difficult to weld and is easy to break when installing lenses or adjusting the curvature of the eyeglass frame, so that the frame structure of the glasses is more solid.

Description

Improved Mirror Frame Bridge

The utility model relates to a picture frame structure, in particular to a structure related to a picture frame bridge.

Generally speaking, eyeglass frames can be divided into plastic frames and metal frames. Metal frames are more popular with consumers than plastic frames because metal frames can give people a refined and bookish look when worn, and metal frames are more popular than plastic frames. It is made of cupronickel or white iron steel. Moreover, cupronickel and white iron steel have their own characteristics, that is, cupronickel is brittle and has poor toughness, while white iron steel has better toughness and elasticity; as for the bridge connecting the two frames, it is also made of cupronickel, Both white iron and steel are used by the industry, but the use of white copper is relatively thick due to its poor toughness and lacks slender aesthetics. Therefore, white iron steel bridges are mostly used nowadays, as shown in Figure 1, which is the traditional metal eyeglass frame. The structure is to directly weld the bridge (A) to the inner edge of the mirror frame (B), and then assemble the upper nose bracket (C) and tripod (D) to complete the overall structure.

Although metal eyeglass frames are more elegant and fashionable, they have the following disadvantages:

1. Bridge welding is not easy

 Because if the mirror frame is made of cupronickel and the bridge is made of elastic white iron steel, the materials of the mirror frame and the bridge are different, resulting in different melting points, which makes it difficult to weld the bridge.

2. The bridge breakage rate is high

The bridge is directly welded to the inner edge of the frame, the welding range is very small, and the welding force is limited, so it is easy to break from the welded end when the lens is installed or the frame is adjusted to match the curvature of the face, and the ability to withstand impact is not good. , often cause the two frames to break apart, which is not conducive to sales for the industry, and the damage rate of glasses is high for consumers, which increases the economic burden.

The purpose of this utility model is to weld the inserts made of cupronickel into the end legs of the bridge, and then weld the inserts to the side edge of the frame of the same material, so that the structure of the overall spectacle frame can be made firmer and The non-performing rate is reduced and the competitiveness of export sales is improved.

In order to achieve the above purpose, the utility model includes components such as a bridge frame, a mirror frame and an insert, wherein the bridge frame can be made of white iron steel with bent end legs; and the mirror frame can be made of white copper; Made of the same material, it is a relatively large block with a relatively large end leg, and a groove is provided in the center of the top end. The end legs at both ends of the bridge frame can be inserted into the groove and welded. And the bridge frame can utilize inserts at both ends, so that it can be easily welded to the relative inner edges of the two mirror frames.

After adopting the above structure, the utility model can indeed improve the following practical effects compared with the conventional structure:

1. The bridge and frame are stronger.

In this utility model, the two ends of the bridge frame are first embedded into the inserts for welding. Because the materials of the inserts and the mirror frame are the same (both are cupronickel or bronze), so that they have the same melting point, the inserts can be easily welded by cupronickel. On the inner edge of the frame, the combination relationship between the bridge and the frame is stronger.

2. The bridge frame is not easy to break, which increases the competitiveness of export sales.

 Because the bridge is combined with the frame by the insert, and the insert and the frame are made of the same material, it is easy to weld and has good strength, and the bridge itself is not easy to break, which reduces the defect rate and increases the competitiveness of export sales.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Fig. 1 is a combined schematic view of a conventional spectacle frame.

Fig. 2 is an exploded view of the utility model.

Fig. 3 is combination embodiment diagram (1) of the present utility model.

Fig. 4 is combination embodiment figure (two) of the utility model.

Fig. 5 is another feasible embodiment diagram of the insert of the present invention.

Please refer to Fig. 2, the utility model aims at improving the conventional mirror frame (white copper) and the bridge (white iron steel) due to different materials so that welding is not easy to lack, but to design a cupronickel insert 3 made of the same material as the mirror frame as the mirror frame 2 The welding intermediary with the bridge frame 1, wherein: the center of the top of the insert 3 is provided with a groove 31 suitable for the insertion of the bent end pins of the bridge frame 1, and the embedded end is welded with white copper to make the bridge frame 1 and the insert 3 are integrated (as shown in Figure 3), and then the bridge 1 is attached to the inner edge of the second mirror frame 2 with the insert 3 at both ends, and the contact edge between the insert 3 and the mirror frame 2 is welded (as shown in Figure 4), so that the welding strength can be improved by using the same material of the insert 3 and the mirror frame 2, and the bridge frame 1 is embedded in the groove 31 of the insert 3, and is welded with cupronickel, Its welding strength is also better than the strength of the direct welding between the bridge frame 1 and the spectacle frame 2, ensuring the excellent strength of the overall spectacle frame.

In addition, the columnar insert used above is only one of the feasible embodiments of the present utility model, and the shape of other inserts 3 is shown in Figure 5, which can be gourd-shaped, or other special shapes and geometric shapes, such as a coke bottle etc., all of these should be within the protection scope of the present utility model.
