The present invention relates to a leak prevention device for a joint pipe, and more particularly, a leak prevention device for a joint pipe which allows a simple structure and a simple fastening to be easily made so as to minimize leakage caused by pressure applied from the ground. It is about.

In general, a joint pipe is installed at a connection portion of a water supply pipe or a drain pipe that is buried underground, and a conventional pipe pipe 110 is screwed to an outer surface as shown in FIG. 4. On one side of the inner circumferential surface of the support, a water supply pipe or a drain pipe is inserted at a position that is introduced by a predetermined distance from one end, and a locking jaw 122 is formed to catch the front end thereof. 120 and a packing 130 including a rubber ring 132, a stopper 134, and a back stopper 136 is inserted into the inclined surface 124.

In the above, the general water-expandable rubber ring is embedded in the rubber ring 130 to maintain more tightness after the fastening.

In addition, the fitting pipe main body 120 is formed in various forms such as L-type, T-type, --type and flange-type according to the portion used.

In addition, the portion of the inclined surface 124 in which the rubber ring 132, the stopper 134, and the back stopper 136, which are the packing part 130 of the fitting pipe body 120, is built, is thinly formed. The cracks and breakages were frequently caused by loads applied from the outside or when strong water pressure was concentrated after the connection work, or frequent changes of water pressure and subsidence of the ground layers caused leakage.

In addition, the locking jaw 122 formed into the inside of the fitting pipe body 120 is also formed at a position drawn in a predetermined distance from one end in proportion to the overall length of the fitting pipe body 120, so that the water supply pipe or the drain pipe is drawn in. The length of the water shortening is also caused by the phenomenon that the tip of the water supply pipe or the drain pipe in contact with the catching jaw 122 when the ground changes, such as sinking due to the separation to the opposite direction occurs.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose is to make the structure simple and intimate fastening also made easy to minimize the leakage phenomenon caused by the ground subsidence or pressure from the outside There is.

Another object of the present invention is to simplify the structure, as well as to facilitate the fastening according to the connection work re-separation.

The present invention for achieving the above object is in the leakage preventing device of the joint pipe consisting of the cap and the joint pipe body and the packing, on the inner circumferential surface of the joint pipe body to form a first slope and the second slope inclined from the end A stepped portion formed between the first and second slopes; The packing may be formed on the outer circumferential surface of each of the third and fourth inclined surfaces corresponding to the first and second inclined surfaces, and may include a locking step portion in which a hollow groove is formed to contact the stepped portion between the third and fourth inclined surfaces. 4 is characterized in that the inclined surface is formed integrally, such as support ribs inclined downward.

In addition, the packing is characterized in that it is formed to have a width protruding to the outside of the fitting pipe body.
