  • the marking is not exposed to the outside, so that the worker can easily know that the coupling is completed. The worker can easily know that the marking is exposed to the outside and the coupling is released.
  • the horizontal length of the coupling groove is preferably equal to the horizontal length of the coupling protrusion such that the marking is not visible from the outside.
  • the present invention can be easily and reliably fastened between the connecting portion, the nut and the tube of the body by the coupling and separation operation by the elastic force of the coupling protrusion and the coupling jaw to prevent leakage, and also lie in the coupling groove 118 By forming a king, there is a remarkable effect that can be confirmed that the coupling protrusions 121 and 131 are coupled to or separated from the coupling groove.

Abstract

La présente invention concerne un outil de fixation de tuyau pourvu d'une saillie d'accouplement et d'une marque de contrôle. Un outil de fixation de tuyau (100) raccorde deux tuyaux gauche et droit (200) et (300) l'un à l'autre. L'outil de fixation de tuyau (100) comprend : un corps (110) qui est positionné au centre entre les tuyaux gauche et droit (200) et (300), les extrémités de pointe des tuyaux gauche et droit (200) et (300) étant respectivement insérées à l'intérieur ; des écrous gauche et droit (120 et 130) qui sont accouplés aux parties de raccordement gauche et droite (111 et 112) du corps (110), respectivement ; et des première et seconde étanchéités (140 et 150) qui exécutent une fonction étanche à l'air entre les parties de raccordement gauche et droite (111 et 112), les écrous gauche et droit (120 et 130), et les tuyaux gauche et droit (200) et (300). La marque de contrôle est formée au niveau de rainures d'accouplement (118) qui sont formées dans les deux parties extrémités d'une unité de corps (115), et les rainures d'accouplement (118) sont conçues pour présenter une longueur constante depuis un palier d'accouplement (119) dans une direction de ligne centrale de tuyau de sorte que les saillies d'accouplement (121 et 131) peuvent être déplacées dans les rainures d'accouplement (118). Selon la présente invention, une fixation pratique et fiable peut être réalisée entre les parties de raccordement, les écrous et les tuyaux du corps et les fuites peuvent être évitées à travers les opérations d'accouplement et de séparation des saillies d'accouplement et du palier d'accouplement au moyen d'une force élastique. De plus, puisque la marque de contrôle est formée dans la rainure d'accouplement (118), l'accouplement à et la séparation des saillies d'accouplement (121 et 131) d'un palier de rainure d'accouplement peuvent être confirmés.
