Description

GERMAN

The object of the invention is a new type of lock with the help of a multi-part clamping ring, which is housed in the clutch housing. The new thing is that the clamping ring goes through its conical design in conjunction with a corresponding cone in the clutch housing the internal pressure of the flowing medium, which is a burden behind a sealing sleeve, is advanced and either engages in an existing groove or engages over a bead and thereby the engaged Holding the male part of a pipe.

Due to this ίη of the clutch itself lying locking all previous external wear parts, such as levers, clamping rings, bolts and other components, superfluous and the clutch is considerably cheaper.

There are hydraulically acting clutches with internal spiral springs known, but for Need a domed male part to hold onto. A spiral spring is placed between the seal and the Buckle clamped to the housing. This retention effect is only proportional low pressures in question.

Compared to known designs, the coupling according to the invention is suitable for high-pressure connections, those at around 20 atm. Test print have produced a surprising result. The plug-in pipe end is cylindrical and not curved. This makes the whole production process considerably cheaper. The area of application is also limited by the secure locking by means of the new type of clamping ring much larger at high pressure than at low pressure. Even thin-walled pipes are suitable for the new coupling applicable, as tests have shown. A bead in the thin-walled tube, the inner stiffener is sufficient to stress the clutch for the highest pressures.

The coupling can be made of drawn thin-walled material, for example steel, brass, sheet metal, plastic, or light metal casting or similar material can be produced.

The drawings show exemplary embodiments of the coupling according to the invention.

Fig. 1 shows a mutual coupling housing a with the pipe end pushed in before it snaps into place. In

Fig. 2 shows the latching. The internal pressure pushes the sealing sleeve g in the direction of the arrow and thus brings the clamping ring into place.

Fig. 3 shows a double socket which has a branch connection to accommodate a sprinkler, hydrant or a water tap. The angularity is twice the size of the Avie with the simple socket.

_ Fig. 4 shows a four-part clamping ring c in plan view. The clamping ring can, however, also be in two parts, in three parts or in several parts.

Fig. 5 shows a spring ring e which centers the individual clamping ring segments.

Fig. 6 shows the same coupling, only with the difference that the clamping ring has a bead / reaches away.

Fig. 7 shows this embodiment after it has snapped into place. The deflection is relatively large, what 7 is particularly symbolized.

In the case of particularly hilly or uneven terrain, double sleeves according to FIG. 3 are used in order to increase the angularity even more. In the drawings, α is the coupling housing, b is the plug-in pipe end and g is a cuff seal that is designed like a garter belt, that is, the part g _t has a corresponding preload, c is the multi-part clamping ring that is inserted into the conical part a _{t of} the housing α by the Internal pressure of the line is shifted with the help of the sleeve g and engages in the groove d.

So that the pipe connection can be taken apart, the groove d is provided with a cone Ci ₁ .

e is a spring ring which, when uncoupling, presses the clamping jaw segments outwards, whereby the release of the plug-in tube end b or the pushing it out of the coupling housing α is easily possible.

In the embodiment according to FIGS. 6 and 7, a bead f is pressed into the pipe end b. This bead has an internal _{reinforcement for}
