A double shrapnel type glasses hinge

Abstract

The invention discloses a double-clip glasses hinge. The double-clip glasses hinge comprises a hinge connector, a hinge tongue and a first clip. The hinge connector comprises a hinging part and a fixing part. The hinge part is provided with a hinge tongue containing groove. The hinge tongue is arranged in the hinge tongue containing groove and is hinged to the hinging part. The fixing part is provided with a first clip containing hole, and the first clip containing hole is communicated with the hinge tongue containing groove. The two ends of the first clip are a rear fixing end and a front outward ejecting end respectively. The rear fixing end of the first clip is arranged in the first clip containing hole. The front outward ejecting end of the first clip is arranged between the hinge tongue and the hinge tongue containing groove. A second clip used for preventing the first clip from being ejected outwards is further arranged on the hinge connector. The second clip comprises a connecting part and a blocking part. The connecting part is fixedly connected with the fixing part. The blocking part is arranged on the outward ejecting side of the first clip in a surrounding mode. The double-clip glasses hinge can limit a glasses arm stably and is long in service life.

Description

technical field [0001] The invention relates to a spectacle accessory, in particular to a double-shrapnel type spectacle hinge. Background technique [0002] Spectacles are simple optical devices made to correct vision or protect eyes. They mainly include spectacle frames and lenses arranged on the spectacle frames. Existing spectacle frames mainly include a frame for carrying lenses and a frame hinged to both sides of the frame. At present, in order to realize the external spring of the frame arm, the structure of the shrapnel type glasses hinge is usually used. The defect is that the elastic force sometimes provided by the shrapnel is not enough, causing the frame arm to easily swing freely, so that the shrapnel loses its support to the frame arm. Limiting effect, and with the long-term use of the glasses, the elastic fatigue of the shrapnel will also occur, which will lose the effect of the shrapnel and shorten the service life of the glasses hinge.

[0002] Spectacles are simple optical devices made to correct vision or protect eyes. They mainly include spectacle frames and lenses arranged on the spectacle frames. Existing spectacle frames mainly include a frame for carrying lenses and a frame hinged to both sides of the frame. At present, in order to realize the external spring of the frame arm, it is usually realized by using the structure of the shrapnel type glasses hinge. The defect is that the elastic force sometimes provided by the shrapnel is not enough, causing the frame arm to easily swing freely, so that the shrapnel loses its support to the frame arm. Limiting effect, and with the long-term use of the glasses, the elastic fatigue of the shrapnel will also occur, which will lose the function of the shrapnel and shorten the service life of the glasses hinge
