Abstract

Złącze składające się z muf (1) montowanych w gniazdach łączonych elementów i łącznika (2) w jakim łącznik (2) ma kształt walca wyposażonego w parę ramion umieszczonych przy każdej z podstaw walca i ustawionych korzystnie pod kątem 90° do osi łącznika, mufy (1) od wewnętrznej strony posiadają profile (ścieżki), a każda z muf (1) posiada co najmniej dwa wewnętrzne profile utworzone przez przylegające do siebie wysokościami kliny, jakich wysokość równa jest połowie wewnętrznej średnicy mufy, korzystnie występuje na 1/3 wysokości mufy b bliżej jej podstawy, a powierzchnie klinów nie są płaskie lecz lekko zagięte ku wysokości klinów i mają kształt wycinka linii śrubowej o przesuniętym lub wydłużonym skoku, przy czym oba profile są zestawione tak, że schodzą się wzdłuż jednej linii śrubowej, a kąt pomiędzy linią zbiegu, a dnem profilu rozprężającego wynosi nie mniej niż 5°, korzystnie 15° a nie bliżej niż w 2/3 głębokości mufy jej profil wewnętrzny posiada klinową bruzdę - granicę rozciągania łącznika.The connector consists of sleeves (1) mounted in the sockets of the connected elements and the connector (2) in which the connector (2) has the shape of a cylinder equipped with a pair of arms located at each of the bases of the cylinder and positioned preferably at an angle of 90 ° to the axis of the connector, 1) from the inside they have profiles (paths), and each of the joints (1) has at least two internal profiles formed by adjacent wedge heights, whose height is equal to half of the inside diameter of the muff, preferably it is 1/3 of the height of the muff b closer to its base, and the wedge surfaces are not flat but slightly bent towards the height of the wedges and have the shape of a helix section with a displaced or elongated pitch, with both profiles aligned so that they converge along one helix line, and the angle between the vanishing line, and the bottom of the expansion profile is not less than 5 °, preferably 15 ° and not closer than 2/3 in depth its internal profile has a wedge-shaped furrow - the stretching limit of the connector.
