Description

Technical Field

[0001] The utility model relates to the technical field of spectacle frame hinges, in particular to a spectacle frame hinge with adjustable tightness. Background Technique

[0002] A pair of spectacle frames generally consists of main parts such as a lens ring, a nose pad, a hinge end, and temple arms. In addition to the above components, there are also temple tips, nose pad screws, hinge screws, etc. Lens ring (frame): The assembly position of the lens, which uses metal wires, nylon wires, and screws to fix the lens by means of grooves or drill holes. It affects the cutting of the lens and the shape of the spectacle. Nose bridge: Connects the left and right lens rings or is directly fixedly connected to the lens. The nose bridge can be directly placed on the nose or supported on the nose through the nose pads. Nose pad: Includes a nose pad stem, a nose pad box, and a nose pad. The nose pad is in direct contact with the nose and plays a role in supporting and stabilizing the spectacle frame. Some plastic frames formed by casting may not have a nose pad stem and a nose pad box, and the nose pad is connected to the lens ring. Hinge end: The connection part between the lens ring and the temple arm, generally bent. Temple arm: Hooks on the ears and can move. It is connected to the hinge end and plays a role in fixing the lens ring. Hinge: A joint connecting the hinge end and the temple arm. Spectacle frame locking block: Tightens the screws to fasten the locking blocks on both sides of the lens ring opening, thereby fixing the lens. The spectacle frame is made of a mixture of metal and plastic. Some of these spectacle frames wrap the plastic with metal, that is, partially or completely wrap it with celluloid; some use different materials in different parts of the spectacle frame, that is, the front frame is plastic and the temple arms are metal, or the front frame is metal and the temple arms are plastic; some use a combination of the above two methods, such as the brow bar and the nose bridge use plastic, the frame uses stainless steel material, and the temple arms use plastic wrapped with metal material. The hybrid frame has a delicate and beautiful shape, giving people a sense of elegance. Because the outer layer of plastic is in close contact with the inner layer of metal material, it is not easy to burn, increasing the strength of the spectacle frame.

[0003] The application number is 201710200453.2, which discloses a combined structure of a spectacle frame, a hinge, and temple arms. It can simply assemble the spectacle frame and the hinge and the hinge and the temple arms, and the temple arms that rotate around the hinge and fold and unfold can stably maintain the folded and unfolded states. An insertion part is formed inside the spectacle frame, and an insertion groove for inserting the insertion part is formed in the fixing part of the hinge, so that the fixing part of the hinge can be simply inserted inside the spectacle frame, and the hinge can be fixed inside the spectacle frame through the insertion part and the insertion groove, enabling the operator to conveniently assemble and maintain the spectacle frame and the hinge. And an extension part extending to one side is formed on the protruding part inside the temple arm, and a first card slot and a second card slot are formed on the rotating part of the hinge for connecting the temple arm. Thus, the extension part is limited respectively based on the folding and unfolding of the temple arm, so that the temple arm stably maintains the folded and unfolded states.

[0004] The combined structure of the spectacle frame, hinge and temple disclosed in the above-mentioned public document has the following defects: This combined structure of the spectacle frame, hinge and temple cannot adjust the tightness according to the user's own situation during operation.

[0005] It can be seen from this that the existing combined structure of the spectacle frame, hinge and temple does not have a direct device for adjusting the tightness of the hinge of the spectacle frame, and it is necessary to improve the existing deficiencies to provide a spectacle frame hinge with adjustable tightness.
