However, it is difficult to maintain airtightness, There is a disadvantage that the long pipe must be rotated to join the pipe.

In recent years, as shown in Fig. 4, tightening threads are formed on the outer circumferences on both sides of the joint pipe, and a locking protrusion is formed on the inner side of the joint pipe to insert the annular packing, the tightening cap is inserted into both ends of the joint pipe, So that the pipe is fastened to both ends of the joint pipe.

However, this structure has a problem in that the structure of the periphery of the joint pipe for pressing the inner packing to adhere to the pipe is complicated, and airtightness due to the packing is often not maintained.

In addition, when using such a conventional pipe fitting, it is impossible to confirm to which portion of the pipe the inserted pipe has been inserted and whether the pipe has been securely fastened. Thus, the annular packing portion provided inside does not come in close contact with the pipe, There was a problem that it was more difficult.

In addition, when the pipe fails to securely connect to the joint pipe, there is a problem that leakage occurs to the outside and foreign substances are injected into the pipe.

In addition, in the case of the insertion hole into which the pipe is inserted in the pipe connecting pipe, if the pipe is prevented from being inserted, the foreign substance is inserted, so that there arises a problem of sealing even after inserting the pipe, There is a problem in that it can not be confirmed whether or not it is inserted.
