Description

The The invention relates to a device for firmly connecting a hose end with a connection nipple, for example, in another nipple is formed plugged and by means of a nipple completely encompassing, having two half-shells sleeve-like element a compact connection element forms two hose line ends, wherein the or the connection nipple and the hose end between receiving ferrules the tensile force of the hose counteracting ribs and at the end Have rounding, and the compression sleeve the nipple towering over in length.

As the generic description of hose connections are the conventional hose nipples, too referred to as spouts, as well as the corresponding with these Press sleeves over the entire length with Ribs provided. To the on the hose or hose connection to absorb acting forces with such a compound to be able to, it needs a corresponding length of grommet and compression sleeve. With such fasteners However, the flexibility of a hose sections existing Hose considerably restricted. Furthermore, it must be on it be noted that with increasing the diameter of hose and Connecting element the sizes unwieldy heavy and more problematic in terms of flexibility are.

One Another disadvantage of the current, forming the state of the art Hose connections is that grommets and press sleeves through little rounded ends in stronger and particular angled movements of the hose the inner cover of the hose affected, d. H. possibly the hose up weaken to tearing.

After DE-OS 2,433,347 is a clamping coupling is known which has in particular at the ends of the cooperating parts, such as spout or compression sleeve, rounding. For the pressing process, however, a special pressing tool is needed, which is tailored to the interaction of provided in the grommet and clamping sleeve ribs and grooves, although arranged at the ends of spout and compression sleeve rounding have no effect on the tensile force of a hose counteracting self-locking.

Of the Invention is now the object of a device for Connecting hose ends with connecting nipples to create a greater flexibility of the hose allowed for appropriate movements due to the compactness allows better handling, while sparing the Hose ends can absorb high tensile forces and at the same time when absorbing tensile forces, an increase in Self-locking of the pressed-in hose brings with it.

These The object is achieved according to the invention that the compression sleeve towards the end of a conical enlargement and inwardly two bulbous, between them a depression having rounded fillets, wherein after the pressing process, the rounding and the recess with a recess and a rounding at the end of the hose nipple correspondingly receive the hose between them.

Of the Advantage of each other to protect the hose corresponding Connecting parts, such as hose nipple or grommet and compression sleeve, result in a shorter design and better absorption larger Tensile forces. The special training of the hose receiving Parts cause a narrowing on the hose and thus an improved Self-locking.

If the conical extension at the end in a short inward Angle passes, thereby facilitating the Pressing an even better correspondence of ribs and depressions regarding the binding of the hose.

at Hoses with metal inserts prove to be advantageous instead of the ribs circumferential beads on each other to provide facing sides of the connecting parts.

Of Further, it is within the scope of the invention as particularly advantageous to see that the pull-out on the hose nipples extended is formed, whereby at larger tensile forces through the tube between the rounding on the one hand and the ribs or beads on the other hand, a stronger self-locking Constriction of the tube can be brought about.

Two Embodiments of the invention are in the drawings reproduced and will be explained in more detail below. Show it:

1 a section through a hose connection as an embodiment with the device according to the invention and

2 a further embodiment of the invention with an inwardly angled conical extension.

The embodiment according to 1 shows the device for firmly connecting two smart sponding 12 . 12 ' as well as the corresponding hose nipples 2 . 3 and ferrules 13 , Furthermore, in the embodiment, a connecting element 1 indicated, in which the plug-in and overlapping Einstecknippel 2 . 3 from a two half-shells sleeve-like element 7 be connected to a unit, with a lock nut 8th the half shells against unspecified shoulders presses. Between the bottom and top end of the insertion 5 and overlap 6 is a sealing ring 4 intended. The connection nipples 2 . 3 , or also referred to as spouts, have a plurality of ribs in conventional construction 10 and at the end a bead 9 with an upstream recess 20 on. The press sleeves 13 with a right angle inwardly angled exit guard 18 and unspecified prior art viewing ports, however, offset from the ribs 10 , also several ribs 14 and at the end within the conical extension 19 two roundings 15 . 16 on, a depression between them 17 form.

After the pressing process, the exit guard picks up 18 in the extended tear-out groove 11 one and, as the left half of the picture shows, forms the compression sleeve 13 after the first occurrence of tensile forces and a movement of the compression sleeve 13 through the extended tear-out groove 11 ultimately a parallel arrangement to the nipple 3 , The bead 9 forces the hose 12 ' into the depression 17 and the rounding off 15 forces the hose 12 ' into the depression 20 , Which, with appropriate traction a considerable self-locking of the hose 12 ' is effected. In this way, ensure the formation of the ends of the hose nipple 2 . 3 and the corresponding compression sleeve 13 a shorter construction.

In the embodiment according to 2 has the conical extension 19 , at the end with a bead 16 , provide an inward bend 21 on. The angulation 21 facilitates the pressing process and allows improved correspondence of the recess 17 and the rounding off 15 the compression sleeve with the bead 9 and the depression 20 the connection nipple 3 to.

For hoses 12 . 12 ' with metal inserts it proves to be expedient, instead of ribs 10 . 14 to use beads at appropriate intervals. As not shown in the drawing, it is possible to the Ausreissnut 11 extended to train at correspondingly high tensile forces by a narrowing between the bead 9 and the rounding off 15 . 16 a greater self-locking and thus to achieve a shorter design. The device according to the invention can be used not only in the connection of two hose ends, but wherever there is a hose end 12 . 12 ' with a connection nipple 2 . 3 by means of a compression sleeve 13 to be connected.
