Description

Technical Field

[0001] The utility model relates to the technical field of glasses, and specifically relates to a folding structure of a lens sleeve. Background Art

[0002] The TR material (plastic titanium) lens sleeve has the characteristics of super toughness, impact and abrasion resistance, and low friction coefficient, etc., which can effectively prevent the injuries to the eyes and face caused by the fracture and friction of the spectacle frame during sports. The existing lens sleeves are designed in a foldable form for convenient carrying, but the folding positions of the existing lens sleeve legs usually adopt a screw structure. The frequent rotation actions make the folding positions prone to looseness or detachment, and it is relatively inconvenient to use. Content of the Utility Model

[0003] The purpose of the utility model is to provide a folding structure of a lens sleeve to solve the above problems.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A folding structure of a lens sleeve includes folding temple pieces. The folding temple pieces include a front temple section, a rear temple section, a male connector, a female connector, a connecting spring piece and a folding hook. The male connector and the female connector are respectively arranged at the rear end of the front temple section and the front end of the rear temple section. An elastic interface that penetrates up and down is arranged at the connecting end of the male connector. The front side wall of the connecting spring piece is elastically connected to the inner wall of the front side of the elastic interface. An embedding hole that penetrates up and down is arranged at the connecting end of the female connector and below the position where the male connector is arranged. The folding hook is arranged on the connecting spring piece, and the hooked part of the folding hook is embedded into the embedding hole from the lower end of the embedding hole. The rear temple section is folded below the front temple section by inwards folding the rear temple section.

[0006] Preferably, the connecting spring piece includes a lower cross plate, an inclined plate and an upper cross plate that are sequentially connected from front to back. The front side wall of the lower cross plate is connected to the inner wall of the front side of the elastic interface. The upper cross plate is arranged parallel to the rear upper side of the lower cross plate. Elastic gaps are formed between the left and right side walls and the rear side wall of the connecting spring piece and the inner wall of the elastic interface.

[0007] Preferably, the connecting spring piece is provided with an installation hole that penetrates up and down. The folding hook includes a connected T-shaped part and a hooked part. The vertical rod of the T-shaped part passes through the installation hole and its horizontal rod is fixedly connected to the connecting spring piece.

[0008] Preferably, both the folding hook and the embedding hole include two groups that are arranged adjacent to each other left and right.

[0009] Preferably, a vertically penetrating n-shaped notch is provided on the front side wall of the connecting end of the female connecting member. There is a folding gap between the vertical rod of the T-shaped part and the inner wall of the n-shaped notch. When the folding temple is in the unfolded or folded state, the connecting end of the rear section of the temple is closely attached to the bottom surface of the connecting end of the front section of the temple.

[0010] Preferably, the connecting ends of the front section and the rear section of the temple are respectively provided with a first installation notch and a second installation notch. The male connecting member and the female connecting member are respectively fixed in the first installation notch and the second installation notch by screws.

[0011] Preferably, it further includes a lens frame and a center beam seat. There are two groups of the lens frames, which are respectively hinged on both sides of the center beam seat. An articulated seat is provided on the outer side wall of the lens frame, and the front end of the folding temple is hinged on the articulated seat.

[0012] After adopting the above technical solution, the present utility model has the following beneficial effects:

[0013] The present utility model provides a folding structure for a folding lens. The front section and the rear section of the temple are folded or unfolded through the cooperation of the male connecting member and the female connecting member. When in use, the rear section of the temple is flipped. The female connecting member rotates along the folding hook on the male connecting member through the embedding hole. During the rotation process, the connecting end of the female connecting member presses against the bottom surface of the male connecting member, thereby pulling down the connecting elastic piece, so that the female connecting member can be flipped smoothly. After the folding or unfolding is completed, at this time, the connecting elastic piece rebounds, and the folding hook pulls the female connecting member upward so that the female connecting member tightly fits against the bottom surface of the male connecting member, preventing up and down shaking, ensuring the stability of the connecting position in the folded state or the unfolded state, avoiding the risk of loosening and falling off at the connecting part. There is no screw structure, which can not only quickly complete the installation or disassembly of parts, but also is not easy to loosen and fall off, and has good use effect.
