Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the embodiment of the present invention: a pair of glasses with rotatable pile head folding glasses legs comprises a glass frame 2, a pile head 3 and a glass leg 1, wherein the glass leg 1 is hinged with one end of the pile head, the end parts of the two sides of the glass frame are provided with convex columns 4, the convex columns 4 are matched and butted with the other end of the pile head, in the embodiment, the profiles of the corresponding matching end surfaces of the mutual butt joint of the convex columns 4 and the pile head 3 are matched and matched, wherein the matching end surfaces of the pile head ends are provided with a circular profile surface which is uniform and concave-convex in shape by taking the center as the center of the circular profile surface, the concave-convex intervals of the profile surface are provided with a plurality of same pile head convex parts 31 and pile head concave parts 32, the pile head convex parts are uniformly distributed on the profile surface at equal angles of the circumference, at least one group of four convex parts which are mutually and vertically arranged at 90 degrees are formed on the profile surface, wherein the matching end surfaces of the 4 ends of the convex columns are provided with corresponding convex column convex, an elastic connecting piece is arranged between the convex column 4 and the pile head 3 for matching and butting so that the corresponding matching end surface forms rebound limit; the matching end parts of the convex columns 4 and the pile heads 3 are arranged to be cylindrical, so that the circular contour surface is conveniently formed, and the matching end surfaces which are arranged to be cylindrical in a matching way are conveniently and externally flush and attractive.
