Problems solved by technology

In order to be able to counteract high tensile forces with sufficient resistance, the externally threaded base body of the retaining seal must be made of high-quality and therefore expensive material
Furthermore, there is the problem that the retaining element, which is pressed onto the base body and is provided with retaining claws, can loosen from the base body due to existing manufacturing tolerances or during frequent handling, so that the inserted fluid tube can no longer be reliably secured. reliable maintenance of the road

Embodiment Construction

[0059] If nothing else is specified, the following description refers to all embodiments of the coupling device shown in the figures and generally designated with the reference number 1 .

[0060] The coupling device 1 comprises a retaining device designed in the form of a sealing ring, which is referred to as the retaining seal 4, and which is held in its figure 1 , 5 , 9, 13, 17 and 21 are engaged in the fixing hole 3 of the separate carrier member 2 and fixed in the fixing hole 3 in the use positions shown in .

[0061] The coupling device 1 is suitable for coupling a fluid line 5 which is designed to conduct a fluid pressure medium, for example compressed air or compressed liquid, therethrough. Preferably, the connectable fluid line 5 is a flexible hose. However, it can also be a rigid tube. exist figure 1 , 9 The fluid lines 5 are shown in the coupled state in and 17 .

[0062] The retaining seal 4 itself can already form the coupling device 1 . The retaining seal ...

Abstract

A connecting device (1) for a fluid line (5) is proposed, having a retaining sleeve (4) which can be fixed in an inner thread (13) of a fastening opening (3) of a support component (2). A retaining element (24) belonging to the retaining sleeve (4) is equipped with retaining claws (37) which can act on the outer circumference of an inserted fluid line (5) in order to securely hold the latter. The retaining element (24) is moreover equipped with a plurality of securing arms (38), which form engagement projections (52) lying on a helical line (48) whose pitch corresponds to the pitch of the inner thread (13). Since the engagement projections (52) engage in the inner thread (13), they bring about a secure fastening of the retaining sleeve (4).

Description

technical field [0001] The invention relates to a coupling device for fluid lines with a retaining sealing ring, which is designed to be inserted with its front side first into a special carrier component with an internal thread in the use position. In the fixing hole and fixed in the fixing hole by engaging into the internal thread, and the retaining seal ring is axially passed through the insertion hole, the fluid line to be connected can be inserted into the insertion hole starting from the rear side of the retaining seal ring , wherein the retaining seal has an annularly structured retaining element surrounding the insertion hole, the retaining element has a plurality of obliquely radially inwardly projecting retaining pawls, which are configured for their fastening purposes The outer periphery of the fluid line inserted into the insertion hole is loaded. Background technique [0002] A coupling device of this type known from document EP 0 185 802 A1 has a retaining sea...
