Flexible tube connection fitting
Abstract
Abstract Translated from Japanese (57)【要約】 【目的】 周方向の一箇所に欠円部を有すると共に、周 方向の複数箇所に凹入部を有するリテーナを用いる可撓 管接続継手において、リテーナの凹入部形成箇所の残肉 部の幅寸法や押輪のリテーナ押付け面の半径寸法の関係 を適切に定めることによって、リテーナによる管端保持 機能を確実に発揮させる。 【構成】 継手本体と、リテーナ5と、リテーナ5を継 手本体の受面側へ押し付ける押輪とを有する。リテーナ 5の凹入部52の最奥部の位置aとリテーナ5の縮径時 の中心位置Pとの間の長さ寸法L1を、押輪の内周側半 径寸法L2と同一かそれよりも長くする。 (57) [Abstract] [Purpose] In a flexible pipe connection joint that uses a retainer that has a circular cutout at one location in the circumferential direction and has recesses at multiple locations in the circumferential direction, the remaining portion where the recessed portion is formed in the retainer. By properly determining the relationship between the width of the flesh and the radial dimension of the retainer pressing surface of the push ring, the retainer can reliably exert its pipe end holding function. [Structure] A joint body, a retainer 5, and a push ring that presses the retainer 5 against the receiving surface side of the joint body. The length dimension L1 between the innermost position a of the recessed portion 52 of the retainer 5 and the center position P of the retainer 5 when the diameter of the retainer 5 is reduced is made equal to or longer than the inner circumferential radius dimension L2 of the push ring. .
