Description

Quick coupling for fluid lines, in particular for hoses

The invention relates to couplings for fluid lines, in particular for hoses.

There are already known couplings, which consist of two elements, d. H. one element to be accommodated and one element to be accommodated, exist, which by Terschraub, clamps or with the help of a coupling independent of the coupling or a other corresponding organs are mechanically connected to one another.

These known couplings have the disadvantage that they, especially if they have an unprotected external thread have, are relatively easily damaged, with ^ provided that the lock is by means of a separate, from the Coupling loose part is achieved, this part can get lost. For the reasons mentioned above, these are clutches for harsh operating conditions such as those for example

The object on which the invention is based "is to To create a coupling which does not have the aforementioned shortcomings, in which the two elements, d. H. that to be recorded and the receiving element without assistance of accessories or any tools by hand or have them detached from one another.

The coupling device proposed according to the invention is characterized in that a projection or a groove provided on the element to be accommodated is included an elastic coupling member cooperates that so is arranged that it engages in the hat or below the heel engages, it in at least an opening provided in the female element, which opening is designed so that the elastic Dodge organ when inserting the element to be picked up can and after the introduction of this element its starting position, d. H. the locking points, again occupies.

To spread apart the elastic coupling member, d. H. to unlock it, and to separate the two A separating element is provided for coupling elements from one another, manual intervention during the separation process makes necessary.

The separating organ is expediently from the one to be recorded Element carried and can consist of a simple ring, which is optionally provided with lugs, which are arranged so that they the part or parts of the elastic coupling member, which can be a simple metal wire, can be pushed back for the purpose of uncoupling.

The invention is explained in more detail below with reference to the exemplary embodiment illustrated in FIGS. 1 to 3 and the variant of a coupling for two hoses illustrated in FIG. 5.
Show it:

Fig. 1 is an external view of the female element of the coupling,

FIG. 2 shows an external view of the element to be accommodated, FIG. 5 shows a longitudinal section through the assembled element

Coupling,
Fig. 4 is a perspective view of the elastic

Coupling organ and
5 shows an external view of an element to be received with a variant of the separating element.

The female element of the coupling according to the invention consists of a central spike-like part 1, onto which the hose A to be connected is pushed, from one Connection piece 2 and one when assembling on part 1

"attached sleeve 3, wmbei the hose according to a" known Technique between the "two last-mentioned parts, i.e. the part 1 and the sleeve 3 is involved.

The connecting piece 2 has two inclined with respect to the axis of the coupling by about 4-5 ° and with respect to a diametrical plane symmetrically arranged slots or grooves 4 and 5. *> An elastic metal wire 6 (Fig. 4) is arranged around the connecting piece 2 in such a way that that its two ends 6a, bent in a suitable manner and perpendicular to the axis of the coupling, are normally engage in slots 4 and 5.

The part to be picked up consists of a central spike-like part 7) a separating element 8 and an outer sleeve 9 _? which is fixed on the central part 7 in such a way that the hose B is tied in between the parts 9 and 9 corresponding to the hose A.

The central part 7 has an extension 10, whose End 11 is designed so that it can be pushed onto the central portion 1a of the female element, one arranged in a groove 13 of this extension Gasket 12 with a circular cross-section causes the seal between the two elements of the coupling.

The separating member 8 is on the extension 10 of the to be received Slidable ring element. It shows

one side has two lugs 14, which are arranged so that they are between the "two in the slots 4 and 5 lying ends 6a of the elastic member 6 are inserted and can act on them; the irenn organ "possesses on the other hand, an end section 15 that enables it to be handled.

It is sufficient to join the two elements of the coupling the insertion of the male element into the female one Element. As soon as the end face of the extension 10 rests against the elastic coupling member, it spread apart, its two ends 6a, by following the inclined surfaces of the slots 4 and 5, as long as Spread apart until they are behind paragraph 16 of the Extension 10 can take their original position again.

In this position of the two ends 6a of the coupling member, the locking is effective, due to the tilted position the locking of seat braids 4 and 5 is stronger, the higher the pressure of the fluid.

In order to separate the two elements of the coupling from each other, it is sufficient, after releasing the pressure in the line or to push the lugs 14 of the separating member 8 between the two legs 6a of the elastic member 6 on the hose and to turn the organ 8 by a quarter turn. Through

this movement, the legs 6a to outside of the Paragraph 16 spread apart, so that the end 11 of the extension 10 is released, and the two elements the coupling can be decoupled.

The uncoupling can therefore only be generated by a deliberate action by hand on the ring 15 and requires two movements, i. H. a displacement and a rotary movement of the ring, so that any danger of a accidental, unwanted separation of the coupling elements ruled out. However, if you want to increase this security by ensuring that the ring 15 does not can be adjusted unpredictably, for example when dragging the clutch over the ground, an additional Safety device, for example one between the ring 15 and the end of the coupling piece 2 inserted spring, are provided for inserting the lugs 14 between the legs 6a of the elastic Coupling member 6 must be compressed.

According to a variant (FIG. 5) of the invention, the separating member is a simple one with a knurled section 18 provided sliding ring 17

In order to separate the two elements of the coupling from each other, it is sufficient to move the ring 17 in such a way that that the legs 6a of the elastic member 6 are spread apart, the ring 17 then against the shoulder

is applied. Since the ring has the same outer diameter as the end 11 of the element to be received, the elastic member slides freely from the ring 17 onto the end 11, so that the two elements of the coupling can be easily uncoupled.

In this device, the security is due to the fact that the risk of unlocking by a accidental, unintentional rotary movement of the separating element is given, further increased.

The invention is of course not limited to the described and illustrated embodiments. Numerous modifications can be made to this, which are obvious to a person skilled in the art according to the intended application, without thereby departing from the scope of the invention. For example, the shape of the elastic Locking device and the shape of the unlocking device can be modified. The same could also be the case sealing type of coupling as well as the seal several: / have variants in connection with the locking device stay within the scope of the invention.
