TECHNICAL FIELD
[0001] The utility model relates to the field of clip spectacles, especially to a folding chuck structure of clip spectacles. BACKGROUND
[0002] With the increasing prevalence of myopia, hyperopia and other vision problems, people also face the threat of strong light, ultraviolet rays and other eye health when they are outdoors. Although traditional sunglasses can provide effective protection, it is inconvenient and not aesthetically pleasing for users who already wear corrective glasses to wear additional sunglasses. Therefore, clip spectacles have emerged as the times require.
[0003] In the prior art, the original intention of the design of clip spectacles is to facilitate the wearer to quickly switch between myopia glasses and sunglasses in different situations. The sunglasses are fixed on the myopia glasses through the clip, which saves the trouble of carrying multiple pairs of glasses. However, the overall structure of the existing clip spectacles is relatively fixed, and when it is stored, whether it is put into a glasses case or placed in a bag at will, it will occupy a relatively large space. Even when subjected to external pressure or impact, the fixed overall structure has a large stress area, which can easily cause damage such as scratching, deformation or even breaking of the lens. This damage not only affects the aesthetics of the sunglasses, but also can seriously affect their functionality, forcing users to replace or repair them in advance, increasing unnecessary economic burden. Therefore, a folding chuck structure of clip spectacles needs to be improved to solve the above problems. SUMMARY
[0004] In order to overcome the problem of fixed clip spectacles that occupy a large space when stored, and even when subjected to external pressure, the fixed clip structure has a large stress area and is prone to overall structure breakage.
[0005] The technical solution of the utility model is a folding chuck structure of clip spectacles, which includes a main fixed frame, a first rotating rod, a first connecting buckle, a second connecting buckle, a first fixed rod, a connecting bracket, a fastening bolt, and a sunglass lens body.
[0006] As a preferred embodiment, the main fixed frame is provided with a limiting slot at the opposite position of the first rotating rod, and the first rotating rod is rotatably connected in the limiting slot.
[0007] As a preferred embodiment, the first connecting buckle is provided with a rotating slot at the opposite position of the second connecting buckle, and the second connecting buckle is rotatably connected in the rotating slot.
[0008] As preferred, a through groove is formed in the interior of the sunglass lens body, and the fastening bolt is threadedly connected in the interior of the connecting support through the through groove.
[0009] As preferred, the back of the main fixing frame is fixedly connected with a secondary fixing frame, the interior of the secondary fixing frame is rotatably connected with a second rotating rod, the bottom of the second rotating rod is fixedly connected with a first clamping soft pad, the exterior of the secondary fixing frame is fixedly connected with a first connecting rod, the bottom of the first connecting rod is fixedly connected with a second clamping soft pad, the exterior of the second rotating rod is fixedly connected with a fixing shell, the exterior of the fixing shell is fixedly connected with a pressing button, the back of the main fixing frame is fixedly connected with a fixing plate, and the fixing plate and the fixing shell are fixedly connected with a torsion spring.
[0010] As preferred, the secondary fixing frame is formed with a rotating groove at the opposite position of the second rotating rod, and the second rotating rod is rotatably connected in the interior of the rotating groove.
[0011] As preferred, the fixing plate and the torsion spring are both provided with two, the two fixing plates are symmetrically fixedly connected at the back of the main fixing frame, and the torsion spring is fixedly connected between the two fixing plates and the fixing shell.
[0012] The utility model discloses the beneficial effects: relative to the traditional fixed type clamping piece sunglasses, through the rotation second connecting buckle makes connecting support and sunglass lens body can be folded up easily, greatly reduce the volume, convenient for user's carrying while, the clamping piece sunglasses whole after folding makes its own when receiving external force can better dispersion pressure to some extent, reduces the risk of damage, further prolongs the service life of sunglasses, not only promotes the portability, strengthens the adaptability, also improves the durability, thereby avoids the fixed type clamping piece sunglasses, when storage, will occupy the larger space, even when suffering extrusion, the fixed type clamping piece structure stress area is big and is easy to cause the whole structure fracture problem.
