Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1 to 4, a pair of glasses without screws for connecting the crotch comprises a frame 1, a pair of glasses legs 2 disposed at two ends of the frame 1 and a connecting structure 3 for rotatably connecting the front end of the pair of glasses legs 2 to the frame 1, wherein the connecting structure 3 comprises a plastic grain 31, a first bending strip 11 fixedly disposed at two ends of the frame 1 and a second bending strip 21 fixedly disposed at the front end of the glasses legs 2, the second bending strip 21 is rotatably connected with the first bending strip 11 by using the plastic grain 31 as a shaft, the plastic grain 31 is provided with a first buckling groove 311 and a second buckling groove 312, the first bending strip 11 is formed with a first annular portion 111 cooperating with the first buckling groove 311 for limiting, and the second bending strip 21 is formed with a second annular portion 211 cooperating with the second buckling groove 312 for limiting. The utility model adopts the plastic grain 31 to replace the screw to connect the picture frame 1 and the mirror crotch 2, thereby avoiding the phenomena of slipping, loosening and the like caused by the long-term use of the screw; the first bending strip 11, the second bending strip 21 and the plastic particles 31 are simple in matching structure, high in stability and long in service life of products.
