QUICK-ACTING, INVIOLABLE AND LEAKTIGHT FASTENING SYSTEM WITH RIBBED OUTER SEAL

Abstract

A system that uses the male-female coupling concept, by mechanical interference between the serrated toothing on the parts to be fastened permanently together or by way of a sleeve-like couplings, but not before sealing elements which satisfy the IP 68 rating are placed therebetween. The outermost, female part or the sleeve-like couplings have particularly elastic peripheral ribs which allow them to expand sufficiently to fit the serrated toothing, such that the mounting can only be undone by cutting the rib, thus characterizing the violation of the sleeve-like coupling or of the outermost female part having a complex profile, used in the fastening system.

TECHNICAL DESCRIPTION

[0025] The QUICK-ACTING, INVIOLABLE AND LEAKTIGHT FASTENING SYSTEM WITH RIBBED OUTER SEAL, object of this invention, consists of a system using the male-female coupling concept, by mechanical interference, by the engagement of the serrated toothing (1 and 2) of the parts (A and B) to be directly and permanently fastened or by means of sleeve-like coupling (3), not without first receiving between them sealing elements (4) which meet the IP68 degree, the outermost female part (A) or sleeve-like coupling (3) having particularly elastic perimeter ribs (5), which allow their sufficient dilatation for the engagement of said serrated toothing (1 and 2) (5), thus characterizing the violation of the sleeve-like coupling (3) or the outermost complex contour female part using the fastening system.

[0026] More particularly, the invention refers to a quick-acting inviolable and leaktight fastening system since a light manual pressing is all is needed for permanent coupling between the parts (A and B), whether using a sleeve-like coupling (3) or even directly between said parts (A and B), wherein the system consists of the concept of male and female type fitting between the serrated toothing (1 and 2), whose measurements impart a mechanical interference which makes it impossible to naturally remove or dismantle the sleeve-like coupling (3) or parts (A and B).

[0027] Sealing elements (4), that meet the IP68 degree of tightness, are strategically positioned on the contact and/or coupling surfaces which may leak. Therefore, one fastened, the assembly will be tight and free of leaks. On the outer side of the sleeve-like coupling (3) or the female part (A) one can observe perimeter ribs (5) having sealing function.

[0028] The ribs (5) have the same wall thickness as the sleeve-like coupling (3) or the part (A) and contain an opening (6) which enables their sufficient plastic expansion for the serrated toothing (1 and 2) to overlap and return to the starting position immediately after the assembly is complete. Thereby, the inviolability of the sleeve-like coupling (3) and the parts (A and B) is characterized until the evidence, which is clear with the cut of the rib (5); in fact, otherwise it will not be possible to dismantle the system proposed. Said cut will relieve the pressure of the female part (A) on the male part (B) or the sleeve-like coupling (3) on the male part (B) which may be a pipe of any section or even a complex design coupling, for example.

[0029] Therefore, the system may be applied to a sleeve-like coupling (3) as shown in FIGS. 1 and 2, where one can note a stop (7) followed by a relief ramp (8). Moreover, as shown in FIGS. 6, 7 and 8, the same concept can be applied in pieces having complex coupling parts (A and B) in which the female coupling part (A) is external to the male coupling part (B). Finally, as shown in FIGS. 9, 10 and 11, the system can be applied to complex design tubular elements whose end represents the male coupling part (B) and the capping means represents the female coupling part (A) with ribs (5).
