Butt pipe coupling with sliding release ring

Bs butt pipe couplings "are known that with a displaceable unlocking ring are fitted, which is mounted on the coupling plug and ab-r on a collar of the latter is supported. When the plug is pushed into the Coupling socket, the unlocking ring expands one in the coupling socket arranged elastic locking ring for the purpose Unlocking the clutch.

The . Honoring refers to the pipeline couplings the aforementioned kind. It is based on the task of such Couplings to be further developed in the direction that an easy and quick coupling without great effort as well as a secure locking between coupling socket and coupling plug is guaranteed in the coupled position of both parts *. No loose or losable parts should be used, thus the push pipe coupling especially for rough operations , e.g. for mining. In addition, the operator of the clutch should be able to clearly see from the outside whether the coupling is locked or unlocked.

The solution to this problem according to the innovation is characterized by the combination of the following features:

a) The elastic locking ring is designed as a coupling ring spring formed and in an obliquely pierced, with the pushing direction of the coupling plug a point Angle enclosing hat held the coupling socket.

b) In the unlocked position of the coupling, the expanded one engages Ring spring in its recess on the outer circumference of the schiaal, radially slit unlocking ring a.

c) When the coupling plug is pulled out of the coupling socket, the release ring is supported

on a shoulder of the shaft part of the coupling plug away.

The coupling plug is equipped with a stop nut in a manner known per se. A locking rocker arm is hinged to this in such a way that it can serve to limit the coupling position in the folded-down position. ^v When folded up, this rocker arm allows the stop nut to be pushed up to the face of the coupling socket. In this position, the two coupling parts are in the unlocked state. When the toggle lever is folded down, the operator can only insert the plug part into the coupling socket so far that both coupling parts are locked together.

During the coupling process, the widening of the ring spring has to be overcome by an inclined surface of the plug part. The ring spring is supported in the locked state of the "two coupling parts and when pressure occurs in these on a second, opposite inclined inclined surface of the plug part and exerts ever greater pressure with increasing load this inclined surface.

In the I ¹ Ig. 1 "to 7, an embodiment is shown. In the I ¹ Ig. 1" to 4 coupling plug and coupling socket of simplicity are only Depending illustrates half due. Yon the coupling socket is only a broken longitudinal section and of the plug part only the unlocking ring and the front sealing ring are shown in section.

Fig. 1 illustrates the two coupling parts before they are plugged together,

From S * ig. 2 is the locking status of these two parts to see. ".".

S ¹ Xg. 5 shows the coupling socket and coupling plug in the unlocked position.

S ¹ Ig.4 shows the position of the coupling ring spring and the unlocking ring in a certain position on the coupling plug when pulling the two coupling parts apart. In S ¹ Ig. 5 is a schematic of the coupling I-spring ring, in FIG. 6 the radially slotted unlocking ring and

in S ¹ Ig.7 in a rapid section the stop nut with the hinged locking rocker arm is illustrated. - 4 -

In the figures, 1 denotes the coupling socket and 2 denotes the coupling plug ". The coupling plug 2 has a bore 2 ¹ and parts 3," 5 and. 7 different diameters. The a ^ J of the coupling socket 1 facing the shaft part. 3 of the Hpplungs * connector 2 is equipped with a groove 3 * in which a sealing ring 4 is mounted. In the direction applied by the coupling socket 1, the shaft part 3 is ^{adjoined by an inclined surface 6 1} , which increases in diameter "up to a narrow collar 6. As" FIG Shaft part 5 <les coupling plug 2 an inclined "shoulder 5" is provided, which represents the transition from the aforementioned collar 6 to the shaft part 5, which has a smaller diameter than the collar 6. However, the part 5 has a larger diameter than the shaft part 3

A shaft part 7 of larger diameter adjoins the shaft part 5 on the right. On the circumference of the latter there is a Yerriegelungskipphe "bel 9, which is articulated in the stop nut 8 is mounted by means of a bolt 8 *.

The SpphelDel 9 has an end face 9 'which prevent is intended that the coupling plug 2 via the illustrated in IFig.2 Locked position pushed out into coupling socket 1 can be. .

The coupling socket 1 has four coaxial bores of different sizes. The left hole corresponds to that Diameter of the through hole 2 'of the coupling plug 2. The bore 15 adjoining it on the right corresponds to this Diameter of the shaft part 3 of the coupling plug 2. The bore 14 of the coupling socket 2 has the same diameter like the outer diameter of the collar 6 of the coupling plug This is from the pig. 2 and 3 can be seen.

The bore 13 of the coupling socket 1 corresponds to the diameter of the shaft part 7 of the coupling plug 2. Between the bores 13 and 14 is in the coupling socket 1 an oblique angle with the direction of impact of the coupling plug at an acute angle encircling groove Io pierced. In this groove is the Clutch ring spring 11 is arranged.

If the coupling plug 2 is inserted into the holes of the coupling socket "up to the 'locking position of the illustrated in Pig "Both coupling parts introduced, then the frictional resistance of the sealing ring 4 of the coupling plug 2 in the Bore 15 of the coupling socket 1 and the expansion of the coupling ring spring 11 to be overcome. During the insertion process, the ring spring 11 slides over the inclined surface 6 'and the collar 6 of the coupling plug 2 to the position shown in Pig.2. There the ring spring 11 lies on the shoulder 5 'of the Shank part 5 of the coupling plug 2. The unlocking

ring 12 ″ is located on the shaft part 5 in the same position as in I ¹ Ig. 1.

Before the coupling parts 1 and 2 can be brought into the unlocking pitch shown in FIG. 3, the locking rocker arm 9 must be pivoted clockwise about the pin 8 'so that ... it is in the position illustrated in FIGS. 3 and 4 occupies. Only then can the coupling plug 2 be pushed so far into the coupling socket 1 that the left side of the stop ^{nut 8 of the coupling plug 2 comes to rest on the end face I 1 of} the coupling d ο se 1.

Moving the coupling plug 2 from that illustrated in FIG Position in the position according to FIG. 3 has the consequence that the annular spring 11 is expanded by the fact that it slides on the outer circumference of the locking ring 12. If the coupling plug 2 is now pulled out of the coupling socket 1, then the unlocking ring 12 slides from the position shown in FIGS. 1 to 3 into the position shown in FIG Position because its outer circumference is under the pressure of the Ring spring 11 stands.

When the coupling part 2 is pulled out of the coupling part 1, the ring spring 11 comes to rest on the collar 6 of the coupling plug 2. When the latter is further pulled out of the coupling socket 1, the ring spring 11 slides ^{down on the inclined surface 6 1} and then continues to pull out the coupling plug 2 no more resistance.
