Problems solved by technology
[0002] Spectacles are simple optical devices made to correct vision or protect eyes. They are composed of lenses and spectacle frames. The spectacle frames also include a lens frame for fixing the lenses and two mirror legs that can be folded inwardly from the specified unfolded state. When in use, the mirror legs are rotated and unfolded and correspondingly clamped to the ears of the person to wear. When not in use, the mirror legs are folded and closed. The mirror legs of the existing spectacle frame and the lens frame are hinged and pressed by screws, so that the mirror legs and the lens There is a certain damping force between the frames, so that the mirror legs can be properly positioned after being unfolded, and the use comfort is good. However, after the mirror legs are rotated many times, the screws are easy to loosen, and the compression effect on the mirror legs and the lens frame is unreliable. The tightening force is unstable, and the screw needs to be tightened frequently to maintain the pressing force, which not only brings inconvenience to the use, but also easily destroys the thread structure and eventually leads to damage to the eye frame

Embodiment Construction
[0015] figure 1 It is a structural schematic diagram of the present invention, figure 2 for figure 1 Partial enlarged view of A in the middle, as shown in the figure: the spectacle frame of this embodiment includes a lens frame 1 and a mirror leg 2 hinged to the lens frame 1 through a hinge shaft 4, and the hinge of the lens frame 1 and the mirror leg 2 Both are provided with hinge ears (11, 21), and also include an elastic member 3 for elastically compressing both the lens frame hinge ear 11 and the mirror leg hinge ear 21 to generate frictional damping force. The elastic member 3 can be supported on the lens The spring, elastic gasket or elastic rubber between the frame hinge ear 11 and the mirror leg hinge ear 21 or supported between the hinge shaft 4 and any hinge ear can realize the purpose of the present invention.
[0016] In this embodiment, the elastic member 3 is sleeved on the outside of the hinge shaft 4 to elastically compress the hinge ear 11 of the lens frame...

The invention discloses a spectacle frame which comprises spectacle lens frames, spectacle legs and elastic sheets, wherein the spectacle legs are articulated to the spectacle lens frames through articulated shafts; the articulated parts of the spectacle lens frames and the spectacle legs are both provided with articulated lugs; and the elastic sheets are used for compressing the spectacle lens frame articulated lugs and the spectacle leg articulated lugs elastically so as to generate the frictional damping force. According to the invention, the elastic sheets are used for compressing the spectacle lens frames and the spectacle legs, so that compressing force between the spectacle lens frames and the spectacle legs can be kept, further, reliable friction damping force can be provided, so that the positioning function of the spectacle legs after unfolding is ensured, and the spectacle frame is convenient to use, and has good comfort.
