の凹状部８の端部９にて固定してなる点にある。That is, the means adopted by the present invention to solve the above-mentioned problems is a flexible tube for sprinkler piping or the like which is obtained by externally fitting a blade 6 to a thin tube body 1. A nut 14 is rotatably externally fitted to at least one end of the tube body 1, and a ring body 7 having a concave portion 8 on its inner surface is attached to the tube body 1 via the blade 6 in proximity to the nut 14. The tube body 1 is fitted outside, and the tube body 1 in the concave portion 8 is bulged in a convex shape so that the blade 6 is attached to the ring body 7.
It is fixed at the end 9 of the concave portion 8.

拡径量は一定範囲に制限される。When relatively high pressure fire extinguishing water flows from the water supply pipe to the flexible tube, the water pressure acts on the end portion of the tube body 1 to expand the diameter, and the blade 6 is attached to the end portion. Since it is externally fitted, its diameter expansion amount is limited to a certain range.

As shown in FIG. 2B, both end portions 9 of the concave portion 8 are protruded from the tube body 1 via the blades 6. A protrusion provided on the inner peripheral surface on the back side of the ring body 7 while engaging with the annular portion 4.
The tip of the blade 6 is straight pipe part 3 of the tube body 1 by 10
Further, a gap 11 is formed between the inner wall surface of the concave portion 8 of the ring body 7 and the convex portion 6a of the blade 6.
The end portion of the blade 6 is dimensioned so as to be substantially flush with the back surface of the ring body 7.

ない。When the fire-extinguishing water is circulated from the water supply pipe to the flexible tube, the water pressure thereof is added to the straight pipe portion 3 of the tube body 1 to expand its diameter. Since 6 is externally fitted, its diameter expansion amount is limited to a certain range and is not damaged.

るのである。In this case, since the gap 11 is formed between the convex portion 6a of the blade 6 and the inner wall surface of the concave portion 8 of the ring body 7, the convex portion 4 of the straight pipe portion 3 is also formed. Although the diameter increases with the blade 6, both ends 9 of the ring body 7 bite into the blade 6 due to the diameter expansion of the convex portion 4 and the pressure contact force between the blade 6 and the convex portion 4 increases. become. Therefore,
The integrity of the blade 6 and the straight pipe portion 3 of the tube body 1 is enhanced, and the careless detachment of the blade 6 is reliably prevented.

体１が良好に保護されることとなる。That is, the expansion of the convex portion 4 by the water pressure of the fire extinguishing water is utilized to prevent the blade 6 from coming off, and the tube body 1 including the straight pipe portion 3 is prevented by the blade 6 for a long period of time. It will be well protected.

によりブレード６が直管部３に固定されることとなる。When manufacturing a flexible tube, the spacer 12 and the nut 14 are first inserted through the tube body 1 in this order. The outwardly protruding portion 13 of the spacer 12 is the flange portion 5 of the straight pipe portion 3. Abut the front of the nut 14
The inward convex portion 15 of the spacer 12 is inserted while being engaged with the outward convex portion 13 of the spacer 12. After inserting the blade 6 formed in the tube body 1 to a predetermined length, the ring body 7 is contacted with the tip surface of the spacer 12 and the back surface of the ring body 7.
In the state where the ring body is inserted, the convex portion 4 formed by expanding the straight pipe portion 3 by bulging or the like engages the concave portion 8 of the ring body 7 via the blade 6, End 9 of 7
As a result, the blade 6 is fixed to the straight pipe portion 3.

得るに至った。Further, since the blade is engaged with the end of the concave portion of the ring body by bulging the tube main body in a convex shape to serve as a fixing means for the blade, the tube main body receives the fluid pressure when flowing the fluid. The swelling part of the ring expands, the end of the ring body bites, and the pressure contact force between the blade and the swelling part increases, which is a unique effect that the separation of the blade from the tube body can be reliably prevented. Came to get.
