Embodiment Construction

[0040] figure 1 a to 1d, especially figure 1In b, the socket joint represented by reference number 10. The socket joint 10 comprises a socket 12 which is either an integral part of a pipe 14 or connectable to a pipe 14 of this type. For simplicity, all of the following are referred to as pipelines. It should be understood that instead of the pipe 14, fittings or the like could obviously be used. Socket 12 has a longitudinal portion referred to as socket end 16 and has an increased inner diameter than that of pipe 14 . Front face 18 of socket end 16 has a flanged edge 20 extending radially inwards for a length h. The edge 20 is straight at the front face 18 and runs conically on the inner side of the socket end, so that the inner diameter of the edge 20 at the front face 18 is smaller than the inner diameter of the edge 20 at the inner side 22 . Thus, an annular inner surface 24 is formed that extends obliquely with respect to the longitudinal axis. The angle of the annul...

Abstract

The present invention relates to a spigot-and-socket joint for connecting two pipes, pipe fittings or the like, comprising a socket end (16) which is assigned to one pipe and into which a spigot end of the other pipe, which has a support strip (64), can be inserted and which has a radially inward-protruding edge (20) with at least one ring segment-shaped recess (26-29), and a locking device for locking the spigot end in the socket end, in that the support strip rests against the locking device and said locking device rests against the edge, the locking device comprising at least two ring segment-shaped locking elements. The spigot-and socket joint is distinguished in that at least four recesses (26-29) are provided and are arranged with uniform spacing in the circumferential direction, and the two locking elements each have two ring segment-shaped locking parts (52, 54) which are joined together via a respective web (56), the spacing between the two locking parts of a locking element corresponding to the spacing between two recesses.

Description

technical field [0001] The invention relates to a socket joint for connecting two pipes, pipe fittings or the like, comprising a socket end assigned to one pipe, into which a socket end of the other pipe with a support bar can be inserted, the socket The joint end has a radially inwardly projecting edge having at least one annular arcuate groove; and locking means for locking the spigot end in the socket end, wherein the support bar rests on the locking means, and the locking means The device rests on the edge, the locking device comprising at least two annular arc-shaped locking pieces. Background technique [0002] A socket connection of the above-mentioned type is known, for example, from DE 199 18 717 C1. They are used to form a rubber-tight connection between two pipes under normal pressure. For tensile fastening, these known socket and socket joints have locking means to prevent the spigot end of one pipe from being withdrawn from the socket end of the other pipe. ...
