Abstract

The invention concerns a mechanical connector consisting of a tube (1) provided with a flange (2) separating it into two parts (3, 7). One (3) of the parts, or first part, comprises on its outer wall circular grooves (4) and longitudinal identations (5) and further comprises a pin (10) with external diameter slightly greater than said tube (1) internal diameter. The invention is useful for connecting a pipe on a block.

Description

La présente invention est relative à un raccord d'implantation notamment pour raccorder un tuyau à un équipement hydraulique. The present invention relates to an installation fitting in particular for connecting a pipe to hydraulic equipment.

Ainsi qu'il est connu en hydraulique, les liaisons entre différents organes sont habituellement réalisées par des tuyauteries souples ou rigides. Les raccordements intermédiaires sont réalisés grâce à l'utilisation d'éléments d'implantation qui sont vissés dans le corps des équipements hydrauliques tels que blocs, vérins, pompes. As is known in hydraulics, the connections between different members are usually made by flexible or rigid pipes. Intermediate connections are made through the use of installation elements which are screwed into the body of hydraulic equipment such as blocks, cylinders, pumps.

Ces raccords d'implantation de l'art antérieur qui sont vissés, requièrent des opérations d'usinage coûteux et délicats et nécessitent l'utilisation de joint(s) d'étanchéité. These implantation fittings of the prior art which are screwed, require costly and delicate machining operations and require the use of seal (s).

Aussi, un des buts de la présente invention est-il de fournir un raccord d'implantation qui obvie aux inconvénients présentés par ceux actuellement connus. One of the aims of the present invention is therefore to provide an implantation fitting which obviates the drawbacks presented by those currently known.

Ce but, ainsi que d'autres qui apparaîtront par la suite, sont atteints par un raccord d'implantation constitué par un tube muni d'une collerette le séparant en deux parties, lequel raccord est caractérisé, selon la présente invention, par le fait qu'une des deux parties comporte sur sa paroi externe des rainures circulaires et des gorges longitudinales et qu'il comporte également une goupille de diamétre légèrement supérieur au diamètre interne du tube. This object, as well as others which will appear subsequently, are achieved by an implantation fitting constituted by a tube provided with a collar separating it into two parts, which fitting is characterized, according to the present invention, by the fact that one of the two parts has on its outer wall circular grooves and longitudinal grooves and that it also has a pin of diameter slightly greater than the internal diameter of the tube.

De préférence, les gorges longitudinales sont disposées seulement sur une portion des rainures circulaires. Preferably, the longitudinal grooves are arranged only on a portion of the circular grooves.

Avantageusement, la partie du raccord munie de rainures et de gorges comporte à son extrémité libre une butée pour la goupille. Advantageously, the part of the connector provided with grooves and grooves has at its free end a stop for the pin.

De préférence, I'autre des deux parties, ou seconde partie, comporte une paroi intérieure s'évasant en un cône vers son extrémité libre. Preferably, the other of the two parts, or second part, has an inner wall which widens in a cone towards its free end.

La description qui va suivre et qui ne présente aucun caractère limitatif doit être lue en regard de la figure unique annexée qui est une vue en perspective, avec arrachement partiel, d'un raccord d'implantation selon la présente invention. The description which follows and which has no limiting character should be read with reference to the single appended figure which is a perspective view, with partial cutaway, of an implantation fitting according to the present invention.

Ainsi qu'on peut le voir sur cette figure, un raccord d'implantation selon la présente invention est constitué par un tube 1 muni d'une collerette 2 le séparant en deux parties. As can be seen in this figure, an installation fitting according to the present invention consists of a tube 1 provided with a flange 2 separating it into two parts.

Une première partie 3, qui sera introduite ultérieurement par exemple dans un bloc raccord, comporte sur sa paroi interne des rainures circulaires 4 et des gorges longitudinales 5 réalisées sur une partie de ces rainures circulaires 4. A first part 3, which will be introduced subsequently, for example in a connection block, has on its internal wall circular grooves 4 and longitudinal grooves 5 produced on a part of these circular grooves 4.

Selon le présent exemple de réalisation, ces gorges longitudinales sont au nombre de trois, régulièrement réparties et réalisées sur les deux rainures les plus proches de la collerette 2. Les rainures circulaires sont au nombre de 10 dans cet exemple.According to the present exemplary embodiment, these longitudinal grooves are three in number, regularly distributed and produced on the two grooves closest to the flange 2. There are 10 circular grooves in this example.

L'extrémité libre de cette première partie 3 comporte une butée 6. The free end of this first part 3 includes a stop 6.

La seconde partie 7 du tube 1 comporte une paroi intérieure 8 s'évasant en un cône 9 vers son extrémité libre. The second part 7 of the tube 1 has an inner wall 8 which widens into a cone 9 towards its free end.

Le raccord d'implantation comprend également une goupille 10 évidée dont le diamètre extérieur est légèrement supérieur au diamètre intérieur du tube 1, par exemple de 2/10éme de mm Cette goupille 10 est donc insérée à force dans le tube 1 par l'extrémité libre évasée en cône 9 de la seconde partie 7. Cette goupille 10 peut être mise en place soit par pression, soit en la tirant à travers le tube 1. The implantation fitting also comprises a hollow pin 10 whose outside diameter is slightly greater than the inside diameter of the tube 1, for example by 2 / 10ths of a mm. This pin 10 is therefore forced into the tube 1 through the free end flared in a cone 9 of the second part 7. This pin 10 can be put in place either by pressure or by pulling it through the tube 1.

La pression exercée par la goupille 10 lors de son insertion permet de déformer le tube 1: ainsi, les rainures circulaires 4 et les gorges longitudinales 5 sont ancrées dans la paroi interne du bloc raccord, qui est par conséquent refoulée dans elles. Les rainures circulaires 4 assurent l'étanchéité et les gorges longitudinales 5 bloquent le raccord en rotation. The pressure exerted by the pin 10 during its insertion makes it possible to deform the tube 1: thus, the circular grooves 4 and the longitudinal grooves 5 are anchored in the internal wall of the connector block, which is consequently pushed back into them. The circular grooves 4 provide the seal and the longitudinal grooves 5 block the connection in rotation.

La collerette 2 permet d'assurer un bon positionnement du raccord sur un bloc raccord par exemple. The flange 2 ensures good positioning of the fitting on a fitting block for example.

On enfonce la goupille 10 dans le tube 1 jusqu'à ce que celle-ci vienne en butée contre la butée 6. The pin 10 is pressed into the tube 1 until the latter comes into abutment against the abutment 6.

Pour démonter ce raccord une fois implanté, il suffit d'extraire le goupille 10 du tube 1, puis on retire ce dernier. To dismantle this fitting once implanted, simply extract the pin 10 from the tube 1, then remove the latter.

Si nécessaire, le tube 1 peut être équipé d'un clapet ou d'un filtre.  If necessary, the tube 1 can be fitted with a valve or a filter.
