Abstract

Сборка муфты (10) для пластмассовых труб (12), имеющая гайку (14), корпус (20), зажимное кольцо (16) и уплотнение (18). Гайка (14) соответствующей резьбой (28) может входить в зацепление с корпусом (20) и имеет крюковой выступ (36) с наклонной поверхностью (46), которая упирается в соответствующую поверхность (48) зажимного кольца (16) в корпусе (20) и прикладывает к ней силу. Трубу (12) в корпус (20) вставляют через гайку (14), зажимное кольцо (16) и уплотнение (18). При затягивании гайки (14) ее наклонная поверхность (46) входит в зацепление с зажимным кольцом (16), в результате чего на него действуют радиальная и продольная силы. Радиальное сжатие зажимного кольца (16) приводит к тому, что оно зацепляется с трубой (12), а продольная сила вдавливает его в корпус (20), и при этом зажимное кольцо упирается в уплотнение (18) и сжимает его, одновременно с этим втягивая трубу (12) дальше в корпус (20). Кроме того, гайка (14) и корпус (20) могут иметь конусные поверхности (46), которые при вдавливании зажимного кольца (14) в корпус (20) сходятся. Физический контакт между корпусом (20) и гайкой (14) усиливает гайку (14) - отличительный признак, особенно желательный при использовании мягких пластмасс. Еще одним отличительным признаком является наличие на зажимном кольце (16) манжеты (70), которая обеспечивает дополнительную опору для зажимного кольца (16) при его сжатии. Еще одним отличительным признаком является наличие на гайке (14) упорного буртика (56), который предотвращает вытягивание зажимного кольца (16) из корпуса (20).Международная заявка была опубликована вместе с отчетом о международном поиске.
