DESCRIPCION DETALLADA Y REALIZACIONES DE LA INVENCIONDETAILED DESCRIPTION AND EMBODIMENTS OF THE INVENTION

El taco de expansion 1 comprende un vastago 2 expandible, el cual tiene una forma basicamente cilmdrica, presenta un eje 3 longitudinal y esta realizado, por ejemplo, en material plastico.The expansion plug 1 comprises an expandable rod 2, which has a basically cylindrical shape, has a longitudinal axis 3 and is made, for example, of plastic material.

El vastago 2 presenta una parte de su extremo 4 configurada para expandirse tras atornillar el perno de fijacion (no ilustrado) en el taco de expansion 1. The rod 2 has a part of its end 4 configured to expand after screwing the fixing bolt (not shown) into the expansion plug 1.

Segun una variante de la invencion no ilustrada, la parte del extremo 4 esta provista de una pluralidad de ranuras que definen al menos dos lenguetas aptas para alejarse la una de la otra tras atornillar el perno de fijacion (no ilustrado) en el taco de expansion 1.According to a variant of the invention not illustrated, the end part 4 is provided with a plurality of grooves defining at least two tabs able to move away from each other after screwing the fastening bolt (not shown) into the expansion pad one.

El taco de expansion 1 comprende, ademas, una cabeza de extremidad 5 que presenta una forma basicamente circular, se extiende alrededor del vastago 2 perpendicularmente al eje 3 y esta realizada, por ejemplo, en material plastico.The expansion plug 1 also comprises an end head 5 which has a basically circular shape, extends around the rod 2 perpendicularly to the axis 3 and is made, for example, of plastic material.

La cabeza 5 esta provista de un orificio 6 central limitado por una pared 7 interior basicamente cilmdrica, esta realizada en una pieza separada y distinta del vastago 2 y esta conectada con el vastago 2 a traves de un dispositivo de acoplamiento 8.The head 5 is provided with a central hole 6 bounded by a basically internal cylindrical wall 7, this is made in a separate piece and separate from the rod 2 and is connected to the rod 2 through a coupling device 8.

El dispositivo de acoplamiento 8 comprende una pluralidad de aletas de enganche 9 elasticamente deformables que estan realizadas en la pared 7, estan uniformemente distribuidas alrededor del eje 3 y estan normalmente dispuestas en una posicion de enganche, donde las aletas 9 sobresalen en el interior del orificio 6.The coupling device 8 comprises a plurality of elastically deformable latching flaps 9 which are made in the wall 7, are uniformly distributed around the axis 3 and are normally arranged in a latching position, where the fins 9 protrude into the interior of the hole 6

El dispositivo 8 comprende, ademas, una brida 10 de enganche que sale radialmente de una extremidad del vastago 2 opuesta a la parte extrema 4 y permite a las aletas 9 sujetar el vastago 2 tras un movimiento de insercion del vastago 2 en el orificio 6.The device 8 further comprises a coupling flange 10 that extends radially from one end of the rod 2 opposite the end part 4 and allows the wings 9 to hold the rod 2 after a movement of insertion of the rod 2 into the hole 6.

El taco de expansion 1 comprende, finalmente, una tapa 11 que esta conectada con la cabeza 5 y es apta para cerrar el orificio 6 tras atornillar el perno de fijacion (no ilustrado) en el vastago 2.The expansion plug 1 comprises, finally, a cover 11 which is connected to the head 5 and is able to close the hole 6 after screwing the fixing bolt (not shown) on the rod 2.

El taco de expansion 1 presenta algunas ventajas que derivan principalmente del hecho que el vastago 2 es intercambiable, se fija axialmente de manera liberable sobre la cabeza 5, puede sustituirse por otro vastago 2 de longitud diferente y por lo tanto permite utilizar una unica cabeza 5 con una pluralidad de vastagos 2 de diferentes longitudes.The expansion plug 1 has some advantages that derive mainly from the fact that the rod 2 is interchangeable, it is fixed axially in a releasable manner on the head 5, it can be replaced by another rod 2 of different length and therefore allows to use a single head 5. with a plurality of rods 2 of different lengths.

Ademas, puesto que el vastago 2 y la cabeza 5 estan acoplados de manera liberable, el empaquetamiento y almacenamiento de los vastagos 2 y de las cabezas 5 son relativamente simples y economicos. Furthermore, since the rod 2 and the head 5 are releasably coupled, the packing and storage of the rods 2 and the heads 5 are relatively simple and economical.
