Description

Technical Field

[0001] The utility model relates to the technical field of spectacles hinges, in particular to a spectacles hinge structure. Background Art

[0002] Glasses are worn mainly through three points of support formed by the bridge of the nose and the ears on both sides. The existing glasses legs and glasses frames are mainly connected by screws for rotation. This connection method is easy to loosen the screws after long-term wearing. In addition, the screws on the glasses are very small and require special tools to tighten them, which is inconvenient for the wearer to maintain them by themselves.

[0003] The glasses legs connected by screws are mainly worn through the support of the ears. The two glasses legs do not have the clamping effect on both sides of the wearer's head. When the wearer moves with a large amplitude, the glasses are very easy to fall off. This is also a common problem at present. For this reason, we propose a glasses hinge structure. Utility Model Content

[0004] The purpose of the present invention is to provide a hinge structure for glasses in order to solve the above problems, as described below.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a glasses hinge structure, comprising a circular plate, the circular plate is fixed on the head of the glasses frame, a connecting frame is rotatably arranged at the center of the circular plate, and the end of the connecting frame away from the circular plate is connected to the glasses leg;

[0007] A plurality of grooves are evenly distributed on the circumferential surface of the circular plate. A metal spleen is arranged on the connecting frame, and a pin is arranged on the metal spleen. The pin is in clearance fit with the groove.

[0008] By adopting the above-mentioned glasses hinge structure, the glasses legs are rotated, the connecting frame is driven by the glasses legs, and the metal spleen is driven by the connecting frame to move along the circumferential surface of the circular plate. When the metal spleen drives the pin to pass through the convex surface of the circular plate, the metal spleen will deform and generate elastic force. When the pin passes over the convex surface and enters the groove, the metal spleen will automatically expand and restore the original shape. The pin and the groove cooperate to complete the positioning, thereby fixing the connection frame and the glasses legs.

[0009] Each groove corresponds to a different angle of the glasses leg, so that the glasses leg can be adjusted at multiple angles.

[0010] Preferably, the end of the metal spleen away from the temple corresponds to the stump.

[0011] Preferably, the metal spleen consists of two parts, a thick part and a thin part, and the two parts are integrated.

[0012] Preferably, a wear-resistant layer is provided on the circumferential surface of the circular plate.

[0013] Preferably, the circumferential surface of the circular plate is provided with grooves to form a plurality of convex surfaces, and the convex surfaces are arc surfaces.

[0014] Preferably, the junction between the convex surface and the concave surface is designed to be rounded.

[0015] Preferably, the connecting frame and the metal spleen together form a Y shape.

[0016] Preferably, the connecting frame rotates along the width direction of the eyeglass frame.

[0017] The beneficial effects are:

[0018] The metal spleen is driven by the connecting frame to move along the circumference of the circular plate. When the metal spleen drives the pin to pass through the convex surface of the circular plate, the metal spleen will deform and generate elastic force. The pin cooperates with the groove to complete the positioning, thereby fixing the position of the connecting frame and the glasses leg, solving the problem that the connecting screws of traditional glasses legs are easy to loosen. By designing a number of grooves corresponding to different angles of the glasses legs to adapt to wearers with different head circumferences, the deformation effect of the metal spleen enables the glasses legs to be supported by the head and relatively displaced, thereby generating a reaction force applied to both sides of the wearer's head, and the two glasses legs cooperate to clamp the wearer's head, making the glasses more stable after being worn and not easy to fall off.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] See also Figure 1-Figure 3 As shown, the utility model provides a glasses hinge structure, including a circular plate 1, the circular plate 1 is fixed on a stump 3 of a glasses frame 2, a connecting frame 5 is rotatably arranged at the center of the circular plate 1, and a glasses leg 4 is connected to the end of the connecting frame 5 away from the circular plate 1;

[0027] A plurality of grooves 8 are evenly distributed on the circumferential surface of the circular plate 1 , a metal spleen 6 is arranged on the connecting frame 5 , and a pin 7 is arranged on the metal spleen 6 , and the pin 7 is clearance-matched with the groove 8 .

[0028] As an optional embodiment, the end of the metal spleen 6 away from the temple 4 corresponds to the stud 3. This design is to limit the maximum opening angle of the temple 4. When the end of the metal spleen 6 contacts the stud 3, the temple 4 has the maximum opening angle.

[0029] When the metal spleen 6 contacts the stump 3, if the temple 4 is continuously swung outward, the metal spleen 6 will be deformed. This design can leave a certain buffer space for the temple 4, avoiding a rigid connection and causing the temple 4 to break when subjected to external force.

[0030] The metal spleen 6 is composed of two parts, a thick part and a thin part, and the two parts are integrated. The thin part can make the metal spleen 6 easier to deform and improve its elastic effect.

[0031] The deformation effect of the metal spleen 6 enables the temples 4 to be relatively displaced by being supported by the head, thereby generating a reaction force applied to both sides of the wearer's head. The two temples 4 cooperate to clamp the wearer's head, making the glasses more stable after being worn and not easy to fall off. If the head size is too large, the support force for the temples 4 is too great, and the pin 7 will slide into another slot 8 to achieve the effect of automatic force release, thereby protecting the metal spleen 6 and the temples 4.

[0032] A wear-resistant layer is provided on the circumferential surface of the circular plate 1. As the use time increases, the circular plate 1 is continuously worn by the pin 7. Providing the wear-resistant layer can increase the service life of the circular plate 1 and maintain the accuracy of the clearance fit between the pin 7 and the groove 8.

[0033] The circumferential surface of the circular plate 1 is provided with grooves 8 to form a plurality of convex surfaces 10 , and the convex surfaces 10 are arc surfaces, which have a guiding effect and can make the pins 7 slide from the convex surfaces 10 to the grooves 8 more easily.

[0034] The joint between the convex surface 10 and the groove 8 is designed as a rounded corner 9, so that the pin 7 can slide from the groove 8 to the convex surface 10 more smoothly.

[0035] The connecting frame 5 and the metal spleen 6 together form a Y-shape, which has an outward slingshot effect and automatic resilience, and can automatically adjust the width of the two glasses legs 4 according to the face sizes of the glasses wearers.

[0036] The connecting frame 5 rotates along the width direction of the eyeglass frame 2 .

[0037] With the above structure, the temple 4 is rotated, the connecting frame 5 is driven by the temple 4, and the metal spleen 6 is driven by the connecting frame 5 to move along the circumferential surface of the circular plate 1. When the metal spleen 6 drives the pin 7 to pass through the convex surface 10 of the circular plate 1, the metal spleen 6 will deform and generate elastic force. When the pin 7 passes over the convex surface 10 and enters the groove 8, the metal spleen 6 will automatically expand and restore the original shape. The pin 7 cooperates with the groove 8 to complete the positioning, thereby fixing the position of the connecting frame 5 and the temple 4.

[0038] Each groove 8 corresponds to a different angle of the glasses leg 4, so that the glasses leg 4 has multi-angle adjustment.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
