Problems solved by technology

[0008] Known bushings of the above-mentioned type for connecting two tubular elements have certain drawbacks which are mainly due to the fact that when the radial fastening force exerted by the bushing on the flexible tubular element exceeds a predetermined critical value , the flexible tubular element is destroyed by the bushing itself
[0009] The known bushes for connecting two tubular elements of the above-mentioned type also have a further disadvantage in that, due to the aforementioned wall interruption in the inner sleeve, the radial pressure exerted by the flexible tubular element on the bushing is absorbed by the outer coupling is fully absorbed, the outer coupling needs to have a relatively large thickness and thus relatively high cost

Embodiment Construction

[0018] refer to Figure 1 to Figure 3 , reference numeral 1 designates the entirety of the bush for connecting the two tubular elements 2, 3 together.

[0019] The bush 1 has a longitudinal axis 4 , is cup-shaped and comprises an outer coupling 5 and an inner sleeve 6 mounted in the coupling 5 .

[0020] Coupling 5 extends around axis 4 and comprises an enlarged portion 7 and a narrowed portion 8 connected to each other by an annular abutment 9 substantially perpendicular to axis 4 .

[0021] The (narrow) portion 8 is delimited by an annular bottom wall 10 substantially perpendicular to the axis 4 , while the (annular adjoining) portion 9 is delimited by a side wall 11 substantially coaxial to the axis 4 .

[0022] Sleeve 6 extends around axis 4 and is locked axially within coupling 5 between abutment 9 and annular end flange 12 radially inwards from side wall 11 of coupling 5 protrude.

[0023] The sleeve 6 is obtained in one piece and delimited by a side wall 13 coaxial t...

Abstract

A bushing for the connection of two tubular elements (2, 3) has an outer coupling (5) and an inner sleeve (6), which is axially locked inside the outer coupling (5), is provided with a plurality of annular teeth (14) projecting towards the inside of the bushing relative to a lateral wall (13) of the inner sleeve (6), and also has a plurality of annular recesses (16), which are obtained at an outer surface (17) of the lateral wall (13).

Description

technical field [0001] The invention relates to a bushing for connecting two tubular elements. [0002] The application of the invention is particularly advantageous when connecting a flexible tubular element to a rigid tubular element, to which the following disclosure refers explicitly, without loss of generality. Background technique [0003] In order to connect together a flexible tubular element with a rigid tubular element, it is known to produce a bushing comprising an external coupling which is cup-shaped and hooks the ring of the rigid tubular element defined by the bottom wall. [0004] A bushing extends around the end of the rigid tubular member and also includes an inner sleeve axially locked within the outer coupling and having a plurality of annular rings protruding radially inwardly from an inner surface of the inner sleeve teeth, and the annular teeth are arranged in sequence along the longitudinal axis of the bushing. [0005] The inner sleeve typically c...
