Definitions

  • the invention relates to a fastening coupling for corrugated pipes with an elastic sleeve which has an open insertion end for receiving a corrugated pipe.
  • AT 385 340 B discloses, inter alia, a connection and fastening element for circumferentially profiled pipes and hoses for connecting or fastening the same to devices with a hollow body which can be fastened to the device and into which the pipe or hose can be inserted, and with one on the pipe or the hose-attachable cap, which on the one hand can be fastened to the hollow body and on the other hand accommodates a ring in its interior, which can engage at least one radially inwardly projecting section of the profiling of the pipe or hose that runs at least approximately radially Lip.
  • DE 297 16 066 discloses, among other things, a coupling piece for connecting the hose ends of at least externally corrugated hoses with an at least partially cylindrical, insertion openings for the housing to be accommodated with hose ends, the housing receiving the hose ends in one piece at least one over at least part of the inner circumference extending, radially inward locking projection for each hose end and also EPDM and PP as the base material are provided.
  • these and many other similar embodiments to the prior art have the disadvantage that in practice they do not have satisfactory receiving and sealing functions in the long run of corrugated pipes, in particular the coupling of corrugated metal pipes and corrugated plastic pipes.
  • the fastening coupling according to the invention for corrugated tubes and winding tubes initially has an elastic sleeve, in particular a tubular sleeve, which has an open insertion end for receiving a corrugated tube or winding tube.
  • this relates to the material transfer according to the invention - and in one piece, that is to say the sleeve and connecting part form a permanent part, in particular free of adhesive, on the sleeve a non-elastic connecting part, for example with a threaded connection or a plug connection, is attached.
  • the connecting part advantageously has at least one projection which acts as a stop in longitudinal section for the material of the sleeve and / or at least one recess receiving material seen in longitudinal section.
  • the term "elastic" is to be understood in the usual dimensions of sleeves of fastening couplings with a wall thickness of approx. 0.1 mm to approx. 10 mm as tool-free and, in particular, only to be accomplished by hand, elastic, reversible deformability.
  • connection part is designed as a tubular sleeve which has an open insertion end for receiving a corrugated tube.
  • the connecting part has a threaded and / or plug connection.
  • the sleeve consists at least predominantly to completely of an elastomer, in particular of EPDM (ethylene-propylene-diene rubber) or PP (polypropylene).
  • the connecting part consists predominantly to completely of metal or a non-elastomeric plastic, in particular stainless steel, brass, polyamide, polyimide or another high-performance thermoplastic, in particular PEEK (polyether ether ketone) and PEAK.
  • the sleeve advantageously has an inner seal, which is particularly elastic, in particular made of EPDM, so that a high sealing effect or redundancy is achieved in this way.
  • Both the sleeve and the connecting part can be designed such that they have a plurality of insertion ends or threaded / plug connections. Different shapes, such as elbows, T-pieces, are also conceivable, both in terms of the sleeve, the connecting part and the fastening coupling. The following example serves to explain the invention. Show:
  • FIG. 1 shows a fastening coupling according to the invention in longitudinal section
  • FIG. 2 shows a fastening coupling shown in FIG. 1 in a perspective view.
  • Fig. 1 shows a fastening coupling according to the invention in longitudinal section.
  • the fastening coupling for corrugated pipes has an elastic tubular sleeve 1 which has an open insertion end 2 for receiving a corrugated pipe.
  • a non-elastic connecting part 3 is attached to the sleeve 1 without transition and in one piece is made of metal.
  • the sleeve 1 is made of EPDM, while the connector 3 is made of stainless steel.
  • the connecting part 3 has a plug-in connection 6, which functions according to the engaging detent function principle known from the prior art.
  • FIG. 2 is a perspective view of the fastening coupling shown in FIG. 1.

Abstract

L'invention concerne un accouplement de fixation pour tuyaux ondulés et flexibles hélicoïdaux, comprenant un manchon élastique (1) qui présente une extrémité d'insertion (2) ouverte pour loger le tuyau ondulé ou le flexible hélicoïdal. Ledit accouplement de fixation se caractérise en ce qu'une partie de raccordement (3) non élastique est montée sur le manchon (1), sans transition et d'un seul tenant.
