径部の奥に位置させるようにしたものである。(Prior Art) The seal packing used for the pipe joint portion needs to be inserted with a sufficient insertion margin from the taper portion at the mouth of the inner diameter portion into which the seal packing is inserted, and arranged at the back of the taper portion. As means for arranging in such a position, there are two means shown in JP-B-63-9831, one of which is
The connecting pipe is provided with two locking protrusions, the seal packing is fitted, and the washer having the cylindrical portion is fitted to the connecting pipe, and the locking protrusion is directed from the outside to the inside of the connected body in the cylindrical portion. The seal packing is positioned deep inside the inner diameter of the body to be connected, and the other one is to fit the seal packing near the tip between the two locking projections of the connecting pipe. The seal packing is located near the rear end so that the seal packing is located deep inside the inner diameter portion.

難になる。(Problems to be Solved by the Invention) In each of the above-mentioned conventional techniques, since the connecting pipe is provided with the two locking protrusions, the process of forming the locking protrusions is troublesome and the dimension of the portion becomes long. In the case of the type that holds the seal packing with the locking projection, the seal packing may get over the projection and come off at the time of connection unless the height of the locking projection is sufficiently large. However, since it is necessary to mount the spacer ring before molding the locking projection, it becomes more difficult to form the locking projection.
したがって本考案は、１個だけの係止突起を有する接続
管を使用して、シールパッキンを被接続体内径部に充分
な挿入代をもって深く位置させることができる接続装置
を得ることを課題とする。Therefore, it is an object of the present invention to obtain a connecting device that can use a connecting pipe having only one locking projection to deeply position a seal packing in an inner diameter portion of an object to be connected with a sufficient insertion margin. .

The inner diameter d 2 of the inward end edge 8b is a size that allows the connection pipe 5 to be loosely fitted. The total length 1 is a length that is appropriately determined according to the position where the seal packing 7 is pushed in, and the outer diameter D is a size that can be fitted into the inner diameter portion 2. The collar 8 and the pressing plate-shaped fixing member 9 are fitted before molding the locking projection 6 or after molding from the rear end side of the connecting pipe 5. When the seal packing, the collar 8 and the fixing member 9 are attached to the connecting pipe 5 and inserted into the inner diameter portion 2 and the fixing member 9 is fixed to the flange 9 with the screw 10, the connecting pipe 5 is locked at the inward edge 8b. In order to press the projection 6, it is positioned by the thickness of the inward edge 8b, and the seal packing 7 is positioned by the length 1 of the tubular portion 8a.
Therefore, the installation position of the seal packing 7 can be arbitrarily set by setting the length 1 to an appropriate value.
