Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a rotating beam assembly for eyeglasses. Background Technology

[0002] In the field of eyeglass structure, the bridge is the core component that connects the left and right lens rings or directly fixes the lenses. When the bridge is flipped upwards, the left and right lens rings, along with the eyeglasses, can be flipped upwards, which is suitable for some specific eyeglasses, such as sunglasses.

[0003] The existing upward-flipping structure of the center beam generally uses a hinged connection for rotation and is fixed with screws. Although this structure is simple, it is prone to instability due to loose screws after long-term use. It cannot achieve precise angle adjustment and positioning, resulting in a limited user experience. Exposed hinges or connection gaps also detract from the overall aesthetics of the glasses. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a rotating eyeglass beam assembly that achieves precise rotation and self-positioning of the beam while taking into account the compact structure, convenient assembly and disassembly, and discreet appearance.

[0005] This utility model provides a rotating eyeglass bridge assembly, characterized in that it includes a bridge, one side of which is rotatably provided with an elastic connector, and an eyebrow frame is fixedly provided on the elastic connector.

[0006] The central beam includes a beam body, a bushing fixedly mounted on one side of the beam body, a rotating shaft disposed inside the bushing, and an elastic connector including a connecting part with a first connecting hole. A curved part is provided on one side of the connecting part, and an arc-shaped groove is provided on the inner side of the curved part. The rotating shaft is rotatably disposed inside the arc-shaped groove. A retaining groove is provided on the lower inner side of the eyebrow frame, with the bushing and rotating shaft located inside the retaining groove. The lower side of the retaining groove slides against the outer side of the bushing or rotating shaft. A second connecting hole corresponding to the first connecting hole is provided on the eyebrow frame, and fastening screws are disposed inside the first and second connecting holes.

[0007] In a preferred embodiment, the rotating shaft is detachably located inside the bushing.

[0008] In a preferred embodiment, a first groove is provided on the outer side of the eyebrow frame, and the fastening screw is located inside the first groove.

[0009] In a preferred embodiment, the first connecting hole is a threaded hole, and the second connecting hole is a smooth hole.

[0010] In a preferred embodiment, a second groove is provided on the inner side of the eyebrow frame, and the connecting part of the elastic connector is located inside the second groove.

[0011] In a preferred embodiment, a through groove is provided inside the first groove and below the second connecting hole, and the connecting part of the elastic connector passes through the back side of the through groove to the front side.

[0012] In a preferred embodiment, the first connecting hole is a smooth hole, and the second connecting hole is a threaded hole.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention achieves precise rotational connection between the center beam and the brow frame through the combined design of the rotating shaft and the arc-shaped rotating groove. The elastic pressure of the curved part enables the center beam to have self-positioning ability after rotation, effectively preventing shaking or accidental fall-off. It is especially suitable for scenarios where glasses need to be flipped upwards (such as when used in conjunction with a hat brim).

[0015] The center beam, flexible connectors, and eyebrow frame can be quickly disassembled and assembled using fastening screws and detachable pivots, facilitating parts replacement or maintenance and improving product applicability and service life.

[0016] Compact structure and concealment

[0017] The eyebrow frame has a slot that encloses the bushing and the pivot. The side of the slot slides with the pivot to prevent the parts from falling off while maintaining a compact structure. The fastening screws are hidden in the first groove to avoid being exposed and affecting the aesthetics. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1 to 4 As shown

[0029] A rotating eyeglass bridge assembly includes a bridge 1, an elastic connector 2 rotatably disposed on one side of the bridge 1, and an eyebrow frame 3 fixedly disposed on the elastic connector 2.

[0030] The central beam 1 includes a beam body 11. A bushing 12 is fixedly installed on one side of the beam body 11. A rotating shaft 13 is installed inside the bushing 12. The elastic connector 2 includes a connecting part 21. A first connecting hole 22 is provided on the connecting part 21. A bending part 23 is provided on one side of the connecting part 21. An arc-shaped rotating groove 24 is provided on the inner side of the bending part 23. The rotating shaft 13 is rotatably installed inside the arc-shaped rotating groove 24. A slot 31 is provided on the lower inner side of the eyebrow frame 3. The bushing 12 and the rotating shaft 13 are located inside the slot 31. The lower side of the slot 31 slides with the outer side of the bushing 12 or the rotating shaft 13, so that the rotating shaft 13 will not fall off between the bending part 23 and the eyebrow frame 3. A second connecting hole 32 corresponding to the first connecting hole 22 is provided on the eyebrow frame 3. Fastening screws 4 are provided inside the first connecting hole 22 and the second connecting hole 32.

[0031] The rotating shaft 13 is detachably located inside the bushing 12. A first groove 33 is provided on the outer side of the eyebrow frame 3, and the fastening screw 4 is located inside the first groove 33. The first connecting hole 22 is a threaded hole, and the second connecting hole 32 is a smooth hole. A second groove 34 is provided on the inner side of the eyebrow frame 3, and the connecting part 21 of the elastic connector 2 is located inside the second groove 34.

[0032] The center beam 1 of this invention can rotate on the structure fixed by the elastic connector 2 and the brow frame 3 via the bushing 12 and the rotating shaft 13. The brow frame 3 is fixed to other wearable items, such as the brim of a hat, which can make glasses that can be flipped upwards. The center beam 1, the elastic connector 2, and the brow frame 3 of this invention can all be disassembled for easy replacement of parts. After the elastic connector 2 is fixedly connected to the brow frame 3, the bent part 23 has a certain elastic pressure on the rotating shaft 12 inside the arc-shaped rotating groove 24, which can make the center beam 1 have a certain positioning ability after rotation. The center beam 1 is not easy to shake after it stops flipping upwards, and it is not easy to fall off the flipped-up position under the action of the weight of the center beam and the glasses themselves.

[0033] Example 2

[0034] like Figures 5 to 7 As shown

[0035] A through groove 35 is provided inside the first groove 33 and below the second connecting hole 32. The connecting part 21 of the elastic connector 2 passes through the front side of the through groove 35 from the rear side. The first connecting hole 22 is a smooth hole, and the second connecting hole 32 is a threaded hole. The second groove 34 of Embodiment 1 is not provided, and the other structures are the same as those of Embodiment 1. Compared with Embodiment 1, the first groove 33 of the eyebrow frame 3 in Embodiment 2 is located between the connecting part 21 of the elastic connector 2 and the beam 11.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
