Abstract:
A hidden connecting structure for a pipe connector adapted to connect a plurality of pipes comprising:pipe connector body with a plurality of externally threaded open ends, and a plurality of ""C"" shaped engaging members, each of said engaging members being associated with a spring and an internally threaded rotation cover; wherein,each said rotation cover is adapted to receive one of the pipes in a central opening in said rotation cover, each said rotation cover is screwed onto a corresponding one of said open ends, said rotation cover being in contact with a corresponding one of said springs, said rotation cover being gradually tightened to compress said corresponding one of said springs which in turn is in contact with and applies pressure to a corresponding one of said engaging members, said corresponding one of said engaging members thereby securing one of the pipes to be connected in said open ends in a manner such that said external threads, said springs and said engaging members are hidden by said rotation covers when said hidden connecting structure is in use; and whereineach of said open ends includes a tapered diameter-reducing interior wall, and an external wall of each of said engaging members each is formed to have a profile matching that of said diameter-reducing interior wall, and an interior wall of said engaging member has a smooth surface with a constant diameter so as to receive one of the pipes therein with maximum contact area, such that when said engaging member is placed into one of said open ends, said external wall of said engaging member contacts said diameter-reducing interior wall of said open end so that a uniform pressure is applied to an end of the pipe.
