Description

Technical Field

[0001] The utility model relates to the technical field of glasses, and more particularly to a hinge structure with a spring sheet and a hinge structure combination to which accessories can be attached. Background Art

[0002] The connection structure between the frame and the temples is the core element to ensure the overall stability and comfort of the glasses. The connection structure between the frame and the temples of traditional glasses usually adopts a rigid design, that is, after the temples of the glasses are opened, the angle between the temples and the frame is basically in a vertical state, and the temples cannot continue to rotate outward relative to the frame, and do not have the function of elastic outward expansion. Although this type of hinge has a simple structure, it is not suitable for users with large head circumferences. When users with large head circumferences wear glasses, the wearing comfort is affected because they are clamped too tightly. If they are worn continuously, the two temples will be forced to expand outward, which can easily cause damage to the hinge part and affect the service life of the glasses.

[0003] For example, the Chinese patent with the authorization announcement number CN 219609370 U and the patent name is "An elastic hinge for glasses". It solves the technical problem of being able to adapt to different face shapes to a certain extent, but there are still certain limitations on different appearances, material usage and functional compatibility in the structural setting. At the same time, this structure and the traditional hinge structure cannot be matched with other different accessories, have a single function, and cannot meet the actual needs of different users at the same time.

[0004] Therefore, how to provide a hinge structure combination with a simple structure that can be worn by people with different head circumferences, improve wearing comfort and durability, increase diversified appearance and material applications, and can use the minimum space to match different accessories is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides a hinge structure with a spring sheet and a hinge structure combination with additional accessories, aiming to solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] One end of the second connecting member is connected to the mirror frame, and the other end has a second connecting ear; the second connecting ear and the first connecting ear are both provided with an axial hole;

[0010] The spring sheet is an annular structure, and a compensating fracture is formed on its circumferential surface. Both ends of the compensating fracture have limiting protrusions. The spring sheet is clamped between the first connecting ear and the second connecting ear, and the limiting protrusion on the spring sheet close to the first connecting member abuts against the limiting column.

[0011] The fastener is installed on the inner side of the shaft hole and the spring sheet to connect the first connecting member and the second connecting member.

During the opening and closing process of the temple, the spring piece can be pushed to rotate, thereby realizing the elastic expansion of the temple to the outside. When it expands to a certain extent, the limiting protrusion at one end close to the second connecting member abuts against the abutting surface of the second connecting member, effectively preventing the spring piece from continuing to rotate. The utility model has a simple structure and can be applied to frames and temples of different types and materials, with a wider range of applications. At the same time, it can be applied to people with different head circumferences, thereby improving wearing comfort.

[0013] Preferably, in the above-mentioned hinge structure with a spring sheet, the number of the first connecting ears and the number of the second connecting ears are both two. The spring sheet is clamped between the two first connecting ears, and the two second connecting ears are respectively clamped on the outsides of the two first connecting ears, and the first connecting member and the second connecting member can be connected by the setting of the fastener to achieve relative rotation between the first connecting member and the second connecting member.

[0014] Preferably, in the above hinge structure with a spring sheet, the fastener comprises a bolt and a nut, one end of the bolt coaxially passes through the shaft hole and the inner side of the spring sheet, and the other end abuts against the end face of the second connecting ear at the bottom end, and one end of the nut is threadedly connected to the outer side of the bolt, and the other end abuts against the end face of the second connecting ear at the top end. The structure is simple and stable.

[0015] Preferably, in the above-mentioned hinge structure with a spring sheet, the bolt and the nut are both hollow structures with through holes.

[0016] Preferably, in the above-mentioned hinge structure with a spring sheet, a gasket is provided between the first connecting ear, the spring sheet and the second connecting ear.

[0017] The utility model also provides a hinge structure combination to which accessories can be attached, comprising the above-mentioned hinge with a spring sheet, a third connecting member and a fourth connecting member, wherein the third connecting member and the fourth connecting member respectively extend from both ends of the fastener into the center hole of the fastener and are threadedly connected, and the third connecting member and the fourth connecting member both have magnetic suction members to which different accessories can be attached.

[0018] Through the above technical scheme, the utility model provides a hinge structure combination to which accessories can be attached. By setting the magnetic parts on the third connecting part and the fourth connecting part, the structure has a magnetic function. Different accessories can be attached through the magnetic parts according to different needs of users, thereby solving the technical problem of single function in the prior art and achieving diversification.

[0019] Preferably, in the above-mentioned hinge structure combination with additional accessories, it also includes a lens hanger, and the lens hanger has a first magnet corresponding to the magnetic attraction member of the third connecting member. The magnetic attraction between the first magnet and the magnetic attraction member can replace different lens frames to meet different needs.
