Hinged structure of mirror legs and glasses

Abstract

The invention discloses a hinging structure of glasses legs. The hinging structure comprises a hinging seat and a hinging arm hinged to the hinging seat, wherein the hinging seat is provided with a hinging shaft; the hinging arm is provided with an elastic sheet capable of extending along the length direction of the hinging arm; one end of the elastic sheet is fixedly arranged on the hinging arm far away from the hinging seat; the other end of the elastic sheet is a free end, is located between the hinging arm and the hinging seat and is adjacent to the hinging seat; the free end can swing along the rotary direction of the hinging shaft; the free end has three matching relations with the hinging seat, such as a utilization matching relation, a closing matching relation and an outward turning matching relation.

Description

technical field [0001] The invention relates to a structural part of glasses, in particular to a hinged structure of a mirror leg and glasses with the hinged structure. Background technique [0002] At present, the spectacle frame generally includes a picture frame and a mirror leg, and the mirror leg generally includes a connection part that is hinged together with the picture frame and a hanging ear part that is hung on the ear. One end of the connection part forms a movable hinge with the picture frame. The other end is connected to the hanging ear. In the prior art, the mirror legs are generally made of hard materials or elastic soft materials. When using hard materials, the size of the spectacle frame has been determined, and the mirror legs are weak in deformation , some wearers with larger faces will feel too tight and uncomfortable. If the temples are turned out, they are easy to break and the service life is short. When using soft materials, although the elastic cla...

Problems solved by technology

[0006] In the above structure, because the mirror legs are generally used in conjunction with the mirror frame, the hinged seat can be arranged on the mirror frame to realize the hinged fit between the mirror frame and the mirror leg, and the hinge arm can be directly a part of the mirror leg, or an independent part connected with the mirror leg , the three kinds of matching relationship between the free end and the hinged seat correspond to the use state of the mirror leg one by one. When the legs are not in use, the mirror legs need to be closed and placed, that is, the closed fit relationship between the free end and the hinged seat, and when the angle between the valgus and the hinged seat after the mirror legs are unfolded is greater than 180 degrees, that is, the free end and the hinged seat are valgus Coordination relationship, and the 180 degrees mentioned above are not absolute 180 degrees, they are all approximate values, because the angle between the mirror legs and the hinged seat may be slightly smaller than 180 degrees or slightly larger than 180 degrees when in use, at this time the elastic piece is in a natural state , basically no deformation, the free end and the two sides opposite to the hinged seat may be in contact with each other or there is a gap, the hinged arm can drive the elastic sheet to rotate along the axis of the hinged shaft, when the angle between the hinged seat and the hinged arm is greater than 180 degrees Or less than 180 degrees, the free end of the elastic piece abuts on the hinge seat and receives the abutment force perpendicular to the axis of the elastic piece, and bends and deforms in the direction of the hinge arm. The length direction of the elastic piece is the axial direction, which solves the problem of traditional mirror legs The problem of not being able to evert
