Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a socket connection device,

The present invention relates to a connection socket device of a stainless steel pipe or a PB pipe for preventing leakage. In general, stainless steel pipe is used as a water supply pipe in a home or an office. When it is used as a water pipe, it is important to prevent water leakage when it is connected to a steel pipe or when it is fastened to another pipe having different diameters. Accordingly, the present invention relates to a stiffened pipe which is capable of preventing a leakage at a fastening point while ensuring stable fastening.

The conventional technique related to the present invention is disclosed in Korean Utility Model Registration No. 20-0246590 (published on October 15, 2001). 1 is a view showing the conventional pipe fitting structure. 1, the conventional pipe fitting has a thread 111 formed on the outside, a connection pipe 110 in which an end of the pipe P1 is tightly inserted and fixed, and a pipe 110 inserted into the pipe 110 A rubber ring 120 and a stopper 140 and a support pipe 130 fitted and fixed by a step 112 formed inside the connection pipe 110. The outer side of the connection pipe 110 is provided with a female screw The assembly cover 160 is assembled. A thin plate 150 in the form of a circular plate which is completely fitted to the projecting step 170 formed inside the assembling cover 160 and completely closes the opening of the assembling cover 160 to prevent the packing member from being separated, Is installed. Since the disk-shaped thin plate 150 is fitted in the protrusion 170 of the assembly cover 160 and fixed in a state of being in close contact with the support pipe 130, the thin plate 150 is not detached from the external impact, The rubber ring 120 and the supporting pipe 130 are securely fixed to the inside of the connecting pipe 110 and the assembling cover 160 Are tightly coupled to each other to form a sealed set, and a packing member is inserted and supported therein. Since the conventional pipe fitting thus configured prevents loss and damage of the inserted packing member and prevents the thread 111 from being exposed to the outside by coupling, it is possible to prevent damage and deformation of the screw thread during storage and movement, will be.

As described above, the conventional technique can prevent the packing member from being lost, but it is difficult to maintain the watertightness at the connection portion in the case of the stainless pipe pipe or the PB pipe water pipe. Further, the conventional pipe fitting having the above-described structure is complicated in structure and requires a separate cover for assembly, which is a problem in that the manufacturing cost is excessively increased. In order to solve the problems of the prior art as described above, the present invention provides a stainless steel pipe connecting socket device for assuring the watertightness of a connecting portion, which is stably fastened, Device.

The present invention relates to a stent pipe connecting socket device for preventing leakage of water, which has a plurality of jaws such as a first step, a second step and a third step, A first socket portion which is spaced apart from the first socket portion and which has a lower thread portion; a stent pipe inserted up to a first end of the first socket portion; A second member inserted into the stent pipe and inserted into the upper portion of the first member, and a second member inserted into the stent pipe and inserted into the upper portion of the first member, A second member inserted into the upper portion of the second O-ring and having an inner groove on the inner side surface and having three slits on an upper surface thereof, and a second member inserted into the first socket portion, the stent pipe, O-ring and second O-ring And a second socket portion fastened to the upper thread of the first socket portion in a state where the second member is fastened.

The stainless steel pipe connection socket device for preventing the leakage of the present invention has the effect of perfecting the watertightness of the connection part. In addition, when the first socket portion and the second socket portion are fastened to each other through a mountain or a mountain, the protruding jaws of the second socket portion function to press the second member inwardly and downwardly The second member also presses the second O-ring so as to completely prevent leakage at the connection portion. Another effect of the present invention is that it is easy to use and easy to maintain because it is easy to fasten and disassemble the connection socket device.
