Description

Technical Field

[0001] The utility model relates to the field of glasses hinges, in particular to a V-shaped glasses hinge structure. Background Art

[0002] Glasses hinges are divided into several types including spring hinges, screw hinges, plate hinges and snap hinges.

[0003] 1. Spring hinge: The spring hinge is composed of an internal screw and an external spring. Its characteristic is that the temples can be bent outward or inward, because the spring in the hinge has a certain elasticity, which can bring a certain comfort to the glasses.

[0004] 2. Screw hinge: Screw hinge is the most common type of eyeglass hinge, which uses screws to tightly connect the two temples together, and the tightness of the temples can be adjusted. The disadvantage is that you need to check whether the screws are loose from time to time.

[0005] 3. Plate hinge: The plate hinge is mainly used for steel wire frames or alloy frames. It connects the plate to the two temples to form a certain elasticity to adapt to different face and head shapes.

[0006] 4. Buckle hinge: Buckle hinge is more suitable for frames with large diopters and thick lenses. Its characteristic is that the accessories use buckle to improve the stability and tightness of the temples.

[0007] For example, a Chinese patent with publication number CN217718302U discloses a pair of glasses that are convenient for replacing spectacle lenses, which relates to the technical field of glasses, specifically a pair of glasses that are convenient for replacing spectacle lenses, including a crossbeam, a frame, a lens, a first protrusion, a stud, a first hinge, a temple, and an anti-slip cover. The frame is welded to the left and right ends of the crossbeam, and the lens is installed inside the frame. The first protrusion is welded to the upper side of the left end of the frame, and a stud is welded on the back of the first protrusion, and a movable groove is opened in the middle of the stud. The present application can release the tight connection between the first protrusion and the second protrusion by loosening the fastening bolts, and can make a gap between the first protrusion and the second protrusion by bending the frame, thereby increasing the clamping area of ​​the frame, and then releasing the fixation of the lens, which can facilitate the disassembly and assembly of the lens, and can effectively avoid the problem of directly limiting the lens with screws and causing damage to the lens.

[0008] In summary, there are many disadvantages for the most common screw hinges, which are summarized as follows:

[0009] ① When using screw hinges, foreign matter, sweat stains, and water droplets often enter the hinge joints, which can easily cause the screws in the hinges to rust, causing the hinges to get stuck;

[0010] ② When taking off or wearing glasses, the user will cause the screw hinge to move over time due to the incorrect gripping posture. After a long time, the screw hinge will loosen in the upper and lower directions, which will shorten the service life of the hinge. Utility Model Content
