Abstract

Instantaneous coupling coupling with safety system for pneumatic pipes, of the type incorporating needles constituted by a pair of rectified cylinders transversely mounted so that they pass through inclined millings made in the wall of a cylindrical body of stationary plug belonging to the female part of the fitting, which with the help of auxiliary elements produce the blocking and release of a plug nozzle subject to the pneumatic supply line, when said auxiliary elements are displaced by a piece-lid constituted by an outer envelope that is it slides longitudinally on the plug body, characterized in that it incorporates, - a spring (13) mounted embracing a plug body (6) and compressed between the base of a coupling part (1) and a needle bushing (10), which it provides the displacement and locking of the needles (9) when exerting pressure on these and being displaced by the slots milling of the plug body (6) in order to produce the locking on a nozzle (16), - a spring (7) mounted embracing the wall circumferences of the needle cap (10), abutting at one end at the head of the needle bushing (10) and in the other in the retaining bushing (8), - a needle bushing (10) which at one end has a circumference wall of narrow thickness through which the spring (13) runs and through which the spring (7) runs, and at the other end has a quadrangular head whose external and internal sides come into direct contact respectively with the inner wall of a cover (11) and with the external wall of the piece of plug (6), - a retaining bushing (8) that at one end serves as support for the spring (7), while on the other, and having the corresponding recess, serves as a housing for a fastening pin (12). ), which in turn is located in the complementary groove provided in the internal wall of the cover (11), - a plug body (6) provided with two diametrically opposed compartments, for receiving safety balls (14), materialized in the form of an opening of inverted trapezoidal section, opened by the area closest to its embouchure, of plug part (6), - a retaining bushing (8) that at one end serves as support for the spring (7), while on the other, and having the corresponding recess, serves of accommodation for a gripping rod (12), which in turn is located in the complementary groove provided in the inner wall of the lid (11), - a plug body (6) equipped with two diametrically opposed rooms, for the housing of security balls (14), materialized in the form of an opening of inverted trapezoidal section, opened by the area closest to its mouth, of limited width to not allow the total passage of the aforementioned safety balls (14) through it, and - balls d and security (14) materialized in the form of small solid spheres located in the aforementioned perforations provided for this purpose in areas diametrically opposed to the plug body (6), (Machine-translation by Google Translate, not legally binding)
