ABSTRACT:
A hidden screw-pressing structure for a pipe connector being comprised of a plurality of "C" shaped engaging members, springs and rotation covers on a plurality of opened ends of the pipe connector; wherein, the opened ends each is formed to have a diameter-reducing wall, the external wall of each engaging member is formed to have the same tapering surface as that of the diameter-reducing wall, an inner screw-pressing wall of the engaging member is formed a straight pipe wall, one of the springs abuts on the top of the engaging member and is subjected to compression of one of the rotation covers, screwing in of the rotation cover compresses the spring to push the engaging member inwardly, the inner screw-pressing wall of the engaging member thereby is given with a function for reducing diameter, in this way the walls of the pipes to be connected are bound by the inner screw-pressing walls, therefore, the pipes to be connected are bound in a hidden mode in the pipe connector without damaging the pipes themselves.
