Claims

[Claims for Utility Model Registration] 1. In an expansion pipe joint in which two joint pipes 6, 6a are slidably fitted to each other, either one of the joint pipes 6, 6a is provided with a convex or concave stopper engaging part 16, and the other joint pipe is engaged with the stopper engaging part 16 to restrict expansion and contraction of both the joint pipes 6, 6a. A spring body 18 is provided, and the spring body 18 is such that an elastic force of a predetermined value or more is applied to both the joint pipes 6, 6a, and the spring body 18 is moved by the stopper engaging portion 16 to the joint pipes 6, 6a. A joint in an expansion pipe joint, characterized in that it is elastically deformable so that the engagement between the spring body 18 and the stopper engaging portion 16 is released when pressed in the direction along the axial direction of the joint. Temporary pipe fixing structure. 2. In the temporary fixing structure of the joint pipe in the expansion pipe joint described in Claim 1 of the Utility Model Registration Claim, instead of the spring body 18, the engaging body 18a which is pressed and biased by the elastic member 31 is attached to the other side. Engagement part 1 for stopper
The engaging body 18a is provided to engage with the stopper engaging portion 16 when a stretching force of a predetermined value or more is applied to both the joint pipes 6, 6a.
When a is pressed in the direction along the axial direction of the joint pipes 6, 6a, it retreats from the position where it engages with the stopper engagement portion 16 against the elastic force of the elastic member 31 and engages with the stopper engagement portion 16. A structure for temporarily fixing a joint pipe in a telescopic pipe joint, characterized in that the joint pipe is configured to be movable back and forth so that the engagement with the portion 16 can be released.
