In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "secured" are to be construed broadly and can, for example, be connected or detachably connected or integrated; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1 to 6, a screwless hinge frame includes a frame body 100, hinge assemblies 300, and temples 200, the hinge assemblies 300 are welded to both sides of the frame body 100, the temples 200 are hinged to the frame body 100 through the hinge assemblies 300, the temples 200 are provided with a limiting portion 210, and the limiting portion 210 interferes with the hinge assemblies 300 to limit the opening and closing angle of the temples 200. Connect mirror leg 200 and frame main part 100 through hinge assembly 300, left out the screw, avoided glasses in the use the frame main part 100 with the not hard up of the tie point of mirror leg 200, come off, increased the steadiness, simple structure is reliable.

In this embodiment, the hinge assembly 300 includes a connecting rod 310 and a rotating shaft 320.

In this embodiment, the rotating shaft 320 is cylindrical, the surface of the rotating shaft 320 is provided with a ring groove 321 for matching with the connecting rod 310 for hinging, and the rotating shaft 320 is provided with a through hole 322 for the temple 200 to pass through.
