Claims

[Claims for Utility Model Registration] ■ A thin metal cylinder a for corrosion and rust prevention is held and inserted into a branch port e provided through the wall of the fluid transport pipe, and the metal cylinder a is elastically bulged and deformed. A pair of clamping bodies that compress the thick elastic body 1 from both sides in the axial direction to elastically bulge and deform the thick elastic body 1 so that its outer circumferential surface closely contacts the inner circumferential surface of the branch port e. 2 and 3, a concentric operating rod 4.5 extends toward the same side along the axial direction so as to be relatively rotatable and slidable, and one of the rods 4 rotates. A first cam body 6 is provided with an operating tool 10 and a cam surface 6a inclined from a plane perpendicular to the rotation axis thereof, and a second cam body 6 is provided with a cam surface 11a corresponding to the cam surface 6a on the other rod-shaped body 5. 11 is a corrosion-proofing and rust-preventing metal tube mounting device for pipe branch ports. (2) The corrosion-proofing and rust-preventing metal tube mounting device for a pipe branch opening according to claim 0, wherein the rotary operating tool 10 is provided on the inner rod-shaped body 4. (2) The corrosion-proofing and rust-preventing metal tube attachment device to a pipe branch port according to claim 0 or 0 of the utility model registration claim, wherein the rotary operating tool 10 is connected to the first cam body 6. ■ The second cam body 11 is separate from the outer rod-shaped body 5, and both 1
1 and 5, the movement in the axial direction during compression is integral;
□ Corrosion-proof and rust-proof metal tube mounting device for a pipe branch port as set forth in claim 2 of the utility model registration claim, which is relatively rotatable. (2) The second cam body 11 is connected to a working outer cylinder 12 that can be fixed to a branch stopper for the fluid transport pipe.Utility model registration Claim 0 provides corrosion protection for a pipe branch port. Rust metal cylinder mounting device. ■ The working outer cylinder 12 is divided into a cylinder part 12A that integrally connects the second cam body 11 and a cylinder part 12B that screws into the branch plug, and both cylinder parts 12A and 12B are slidable in the axial direction and fixed. A corrosion-proofing and rust-preventing metal tube mounting device for a pipe branch port and \ according to claim 0 of the utility model registration claim, which is freely configured.
