Description

Eyeglass lens positioning frame

The creation is a spectacle lens positioning frame, which is designed to be in contact with the lens frame and the frame, and is arranged on the outer periphery of the lens by a ring-shaped positioning frame which can be stably fixed, so that the frame does not directly contact the lens, and the positioning frame can be ensured not at the same time. The sliding displacement is generated, which belongs to the technical category of the improved spectacle lens positioning frame.

Conventional common glasses have a basic structure including a lens frame on which a lens is mounted, and a pair of ear frames pivotally disposed on both outer sides of the frame. In the assembly, in order to enable the lens to be stably positioned in the frame, most of the flanges and grooves can be arranged at the contact portion between the lens and the frame. For example, some glasses are provided with grooves on the inner periphery of the frame. The outer periphery of the lens is provided with a flange; depending on the material of the mirror frame, some glasses are provided with a flange on the inner periphery of the frame, and a groove is formed on the outer periphery of the lens.

The above-mentioned lens is fixed to the conventional structure of the lens frame. When the lens is assembled, if the lens flange grinding processing operation is not accurate enough, it is easy to cause a gap between the lens and the frame contact portion, and these gaps have problems of dirt and dirt. It also makes the stability of the lens after assembly worse. In some cases, the lens or the frame may even fall off the frame if it is slightly touched by external force. Because the outer periphery of the lens is in close contact with the inner edge of the frame, it is affected by the material of the frame. If the hardness of the material is higher than the hardness of the lens material, it is easy to wear or deform due to the pressing of the contact part, whether in the lens. When assembling, when using a person to wear and store glasses, lenses or If the frame is touched by external force, it may also cause cracks in the lens due to the extrusion between different hardness materials, and even cause the lens to rupture and cause safety concerns. This disadvantage is especially common with metal frame glasses.

In order to solve this shortcoming, there are also some types of glasses, and an annular pad body part is added between the lens and the frame. In addition to being used to protect the lens from damage, the annular pad part can also hold the lens in a stable position. However, the above-mentioned conventional use of the annular cushion body parts is obviously more labor-intensive in the installation operation, and in actual use, the annular cushion body parts are not effectively fixed, and sliding displacement is easily generated, so that the frame is also caused. The gap between the lens and the lens affects the stability of the lens assembly.

In order to improve the above-mentioned traditional defects, the present invention provides an improved design of the spectacle lens positioning frame.

That is, the main purpose of the present invention is to provide a cam and a concave hole that can be fitted to each other between the positioning frame and the frame, so that the positioning frame assembled between the lens and the frame can be stably fixed. The spectacle lens positioning frame that does not damage the lens frame.

A further object of the present invention is to provide a spectacle lens positioning frame, which can simplify the assembly operation, quickly position the positioning frame and the lens, and prevent the positioning frame from sliding displacement, thereby greatly improving the stability and safety of the lens after the glasses are assembled.

In order to achieve the above objectives, the author uses the following technical means.

The lens positioning frame of the present invention is assembled between the frame of the glasses and the lens, and can be wrapped around the outer periphery of the lens to ensure the lens is firmly fixed and ensure the safety of the glasses.

The glasses include a pair of frames, and the frames are connected by a middle beam, two mirrors A positioning frame and a lens are arranged in the frame, and a pivot seat is respectively arranged on the outer side of the two frames for connecting the ear frame.

The frame comprises an opening on the outer side of the frame, and an upper screw hole and at least one upper ridge on the upper frame of the opening, and a screw hole and at least a lower ridge on the frame at the lower end of the opening Use a screw to lock the upper screw hole and the lower screw hole, even if the opening on the outside of the frame is sealed, to assemble and fix the positioning frame and the lens.

The positioning frame is an annular body, and has an outer groove on the outer edge surface of the positioning frame, an inner groove on the inner edge surface of the positioning frame, and corresponding to the frame on the positioning frame. The opening portion of the opening is also provided with an opening. At least one upper concave hole is disposed on the positioning frame at the upper end of the opening, and at least one lower concave hole is also disposed on the positioning frame at the lower end of the opening.

When the positioning frame and the lens are assembled, the positioning frame is wrapped around the outer periphery of the lens, and the outer frame of the outer edge surface of the positioning frame accommodates the frame, and the inner groove of the inner edge surface of the positioning frame accommodates the lens to make the positioning frame Forming a buffer and protection structure for the contact portion of the lens and the frame.

When the lens and the positioning frame are assembled in the frame, the upper concave hole and the lower concave hole on the positioning frame can be inserted into the upper and lower convex ridges disposed at corresponding positions on the frame.

The positioning frame assembled at the contact portion between the lens and the frame makes the frame not directly contact the lens, effectively eliminating the gap between the lens and the frame, the lens can be stably fixed inside the frame, and the positioning frame and the frame are mutually For the fitting of the convex and concave holes, in addition to greatly simplifying the positioning frame and the lens assembly operation, the positioning frame will never slide and displace, and the lens stability and the safety of use after the glasses are assembled are improved. Creative purpose.

The construction of the specific embodiment of the present invention will be described in detail below with reference to the drawings.
