一端は普通は作業現場で作られるねじ山をもたねばなら
ず、この作業現場は例えば山ノような所で容鴫に出入り
できずまた電気エネルギーの無い所で、このねじ山はや
っかいな条件の下で作らなければならない。Such an arrangement has the disadvantage that at least one end of each tube or rod must have a thread, which is normally made at the work site, such as in a mountain, where access is not possible. Also, in the absence of electrical energy, this thread must be made under difficult conditions.
この問題点はドイツ国公開公報第２８８６１ａ？４号に

切り込み効果により管壁が破壊され、又は実際上特に９
０°より大きい回転忙対する管の抵抗モーメントを排除
することができるからである。Another disadvantage of the above structure is that it requires only a small increase in mechanical forcing. The reason for this is that the pipe wall is destroyed due to the cutting effect of the clamping member, or in practice, especially when
This is because it is possible to eliminate the moment of resistance of the tube during rotation greater than 0°.
本発明の目的は、現存の構造の欠点を除去する。The aim of the invention is to eliminate the drawbacks of existing structures.
滑らかな円筒状本体、特に蕾又は棒用の締付連結・装置
又は継手を提供することにある。The object of the present invention is to provide a clamping connection, device or joint for smooth cylindrical bodies, especially for buds or rods.

シールリングの機能は締付連結装置の機械的特徴から区
別され、対称特性を与える。本発明装置は高い機械的強
度を有し、かつ高圧流体を運ぶときでも完全な管シール
を供する点に特徴を有する。As can be seen, this structure comprises a sealing ring whose function is distinct from the mechanical characteristics of the clamping connection and gives it a symmetrical character. The device of the invention is characterized by high mechanical strength and by providing a perfect tube seal even when carrying high pressure fluids.

と填二管状本体番を含む。Figure 1 shows an embodiment of the coupling or coupling fitting of the invention, which is attached to the adjacent ends of two cylindrical tubes 1 and 2. Only the upper part of the tube end is shown in the figure. This fitting is the first tubular body B
and two tubular body numbers.
本体８は弾性シールリング５に接する環状の半径方向外
方へ延びる凹部なもつ。割型締付リング６な管端の衝合
端から離して本体８の一端に置く。The body 8 has an annular radially outwardly extending recess in contact with the resilient sealing ring 5. A split clamping ring 6 is placed on one end of the main body 8 away from the abutting ends of the tube ends.

、管外部に組立て前に管の挿入範囲を示すために印をつ
けることができる。The clamping ring adjoins a nearly radially extending annular stop shoulder 9 made at one end of the body 8. As is obvious! ! The coupling part shown in Figure 1 is the part that cooperates with tube 1, and a second substantially identical structure is arranged in symmetrical relation to the right of the figure to engage tube S. The body 8 is thus a symmetrical body and cooperates with the same additional parts as 4 and 6. One body 8 is inserted a sufficient distance into the snow so that the recess containing the sealing ring b is spaced apart from the plane 7 between the abutting ends of the tube. For this purpose, markings can be made on the outside of the tube to indicate the extent of insertion of the tube before assembly, in order to ensure proper operation.

合する点を越えて挿入される。To form the joint, the second tubular body, which may also be referred to as the outer nut 4, is inserted onto the tube l, and then the clamping ring 6 is pressed onto the tube. The tubular member 8 is then press fit onto said tube. The tube is received within a central bore having a diameter greater than its outer diameter. In the process of inserting the tube 1, it is pushed into the recessed part of the seal ring, and it is deformed from the relaxed state shown by the broken line to the shape shown by the solid line. The tube is inserted beyond the point where the entire sealing ring engages the outer surface of the tube 1.

るようになすこともできる。The clamping ring 6 is preferably made of spring steel and is sized to fit in a positive locking manner against the outer surface of the tube 2 on the tube 1 or other fitting. The rings 6 are not completely closed, but have a gap that allows them to be pressed together during the tightening process. This gap can be axial or extend obliquely to the plane containing the rings, so that the unclosed ring areas overlap one another.

一電圧に耐える非常に緊密な管連結が行なわ・れる。。The outer surface of the main body 8 has a radially outward thread 8 and the inner surface of the tubular main body number has a radially inward mating thread. When the parts 8-6 are placed on the tube 1, the outer nut number contacts the outer thread 8 on the main body 8 and is tightened. When these threads engage, a truncated conical inner surface 10 on the main body 4
The tightening presses the ring 6 and presses it against the stop shoulder 9 on the main body B. The frustoconical surface 10 made on the inside of the outer nut number simultaneously presses the clamping ring 6 radially inward. The radially inward surface of the ring 6 is concave.

・Determined as follows. Instead of the tightening ring having a round cross section from the beginning, a ring with a truncated conical outer shape that intersects with one surface 10 can be used. However, if the shape shown in the figure is made of 0 wire, which is a particularly cost-effective shape, both grooves 1
