HINGE STRUCTURE OF CELLULAR PHONE

摘要

PURPOSE: A hinge structure of a cellular phone is provided to integrate a fixing cam and a shaft and to improve a coupling structure, so as to reduce the number of necessary components and improve assembly. CONSTITUTION: A fixing cam(20) is integrated with an oblong shaft(26) in which a fixing plane(22) is arranged in one side and a hooking member(27) is arranged at an edge in the center of the other side. A rotation cam(30) is inserted and installed on the shaft(26) and includes a concave part(32) rotated through the interlinking with a protuberance part(24) of the fixing cam(20). A sleeve(40) facing with the rotation cam(30) includes a hooking protuberance(42) coupled with the hooking member(27) of the shaft(26). A spring(50) is elastically installed between the fixing cam(20) and the sleeve(40). And the fixing cam(20) is integrated through plastic injection molding.
