Pipe connection consisted on interior of a joint pipe

摘要

A pipe connector constructed in the interior of a joint pipe. In the pipe connector, an O-ring made of a flexible rubber, a stop ring which is in tight contact with and supports the outer circumference of the pipe inserted into the joint pipe, and an elastic stopper are installed in sequence such that the pipe connector can be pressed and fixed to the outer circumference of the pipe, which is inserted into and connected to the joint pipe, in order to provide air tightness and water tightness to the pipe. Consequently, the pipe is inserted into the joint pipe with one touch without being detached or dislodged, is coupled such that water tightness can be maintained, and is separated by pressure in the direction in which the pipe proceeds.

主权项

1. A pipe connector, comprising:
a joint pipe having a hollow round shape with an opening in one or either end; a pipe inserted into the joint pipe; an O-ring contained in the joint pipe, the O-ring being coupled to an outer circumference of one end of the pipe to provide water tightness; a monolithic stop ring in contact with and pressing the outer circumference of the pipe, the stop ring having a plurality of cantilevered pressing pieces that are arranged radially and have an inward incline in order to prevent the pipe from moving by pressing the outer circumference of the pipe, wherein the stop ring is within the joint pipe; a stopper interposed between the stop ring and the O-ring, the stopper including a spring having a predetermined amount of elasticity such that the spring applies a force to the stop ring to force the plurality of pressing pieces into the inserted pipe; a push socket partially contained in the stop ring, the push socket being elastically pressed by the stop ring, wherein the O-ring is pressed to the outer circumference of one end of the pipe and is in contact with an inner circumference of the joint pipe, thereby providing water tightness between the pipe and the joint pipe, wherein the stop ring is a round-ring shape and the plurality of pressing pieces are integrated thereto, wherein each of the plurality of pressing pieces has a cross-section defining a trapezoid shape, wherein the trapezoid shape has a top leg, a first base, a bottom leg, and a second base in an order and the first base is in contact with an inner circumference of the stop ring, and the top leg is smaller than the bottom leg such that the second base defines the inward incline of each of the plurality of pressing pieces, and due to the inward incline, an inner diameter of the stop ring decreases along a direction that the pipe is inserted, and wherein the inward incline is configured to be in contact with the pipe.
