Claims

[Scope of utility model registration request]

A telescopic flexible pipe joint that connects fluid transport pipes buried in soil, etc., includes a joint body with a pipe insertion port, and an elastic material that is attached to the periphery of the opening of the pipe insertion port in the joint body. a seal ring, a press ring having a compression edge facing the seal ring and connected around the pipe insertion opening of the joint body by two or more bolts, and a press ring that is inserted into the pipe end of the transport pipe into the joint body. A short cylindrical pipe retaining ring that is fitted while retaining the insertion allowance, and two or more seat plate portions corresponding to bolt insertion holes drilled in the push ring, and an outer periphery of the pipe retaining ring. It consists of a retaining tool in which the adjacent seat plate parts are connected to each other by a retaining rod installed along the surface, and the retaining tool has an expandable and flexible space formed between the retaining rod and the push ring. At the same time,
A retaining piece is provided on the seat plate portion to protrude to the side opposite to the installation side of the retaining rod, and the pipe retaining ring has a cutout part on a part of its circumference so that its inner diameter is the same as the outside of the transport pipe. The diameter is expanded to a larger diameter than the pipe diameter, and both cut ends of the cut section are provided with joint pieces for reducing the diameter toward the outer diameter direction, and the outer circumferential surface of the pipe retaining ring has the above-mentioned joint pieces when the diameter is reduced. A telescoping flexible pipe joint characterized in that engaging pieces are provided in a protruding manner corresponding to each of the retaining rod and the retaining piece of the retainer.
