[0023] In the description of the utility model, it needs to explain that, unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "sleeved / connected", "connected" and the like should be understood in a broad sense, for example, "connected" can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0024] The structural characteristics of the utility model will be described in detail in combination with the drawings of the specification.

[0025] Referring to Figures 1-4 A screwless and welding-free metal cutting glasses hinge, comprising a hinge body 3, the hinge body 3 is made of copper pressure casting, the hinge body 3 is used for connecting the temple 2 on the side of the frame 1. The side of the frame 1 is provided with a lug 11, the end of the lug 11 is inwardly bent to form a U-shaped groove 12, wherein the frame 1, the lug 11 and the U-shaped groove 12 are an integral structure formed by laser cutting of a beta titanium metal plate and then bending of sheet metal, and the temple 2 is made of beta titanium and is formed by laser cutting and bending of a metal titanium plate.

[0026] One end of the hinge body 3 is inserted and fixed in the U-shaped groove 12, in order to facilitate the installation of the hinge body 3, a long hole is cut in the middle of the lug 11, the lug 11 is penetrated to form a plug-in groove 14 for the hinge body 3 after being bent at the bottom of the U-shaped groove 12, in order to make the hinge body 3 inserted into one end of the U-shaped groove 12 to be stably fixed, a fixing hole 13 is arranged in the U-shaped groove 12, the fixing hole 13 is provided with a rivet 4 for fixing the hinge body 3, specifically: one end of the hinge body 3 is embedded into the cut plug-in groove 14, and the rivet 4 is sleeved into the fixing hole 13, and finally the rivet 4 is stamped to fix the hinge body 3 and the frame 1, one end of the hinge body 3 can be fixed in the U-shaped groove 12 through the rivet 4, avoiding loosening and disengaging.

[0027] Referring to Figures 1-7The ends of the temple 2 are bent inward to form two circular arc grooves 21, which are distributed on the upper and lower sides of the temple 2, the other end of the hinge body 3 is provided with a rotating shaft 31, which is distributed on the two sides of the hinge body 3, and the rotating shaft 31 serves as a rotating shaft of the temple 2, the circular arc grooves 21 are nested on the rotating shaft 31. The elastic sheet 22 is cut between the two circular arc grooves 21 and is located on the side of the hinge body 3. When the temple 2 is opened or closed, the elastic sheet 22 generates an elastic force on the hinge body 3, so that the rotating shaft 31 rotates with damping, so that the temple 2 is more stable, and the opening and closing feel is better. In order to make the hinge body 3 fit the elastic sheet 22 better, a positioning block 32 is arranged on the side of the hinge body 3 corresponding to the elastic sheet 22, the positioning block 32 is square, and is used for positioning the temple 2. The elastic sheet 22 is in a relaxed state when the temple 2 is in an open state. During the rotation of the temple 2, the elastic sheet 22 is elastically separated from the outer side of the hinge body 3.
