DE102018006717A1 - ROUND TUBE TIE SYSTEM - Google Patents

Abstract

The invention relates to a round tube and bolt system which is suitable for connecting round tubes and similar components firmly or releasably cold and tightly.

Description

Round pipes are used as a transport route for liquids or gases in technology and in life. In order to make round tubes usable for this purpose, it is known to connect them to other tubes or to connecting elements by means of screws, welding, soldering or gluing. Threads with sealants or cross connections are used in the sanitary area. In construction, pipes for scaffolding (coupling scaffolding and frame construction) are known which use molded parts for connecting flanges, sleeves, clamping rings. In life, round pipes are similar objects, especially round cans, which are used only once because of their simple construction and then disposed of.

To simplify connections, we have set ourselves the TASK to create a system for fixed or detachable connections for round tubes and similar components.

The SOLUTION is proposed to use the round tube and bolt system according to the invention with its possibilities for the tight, fixed or detachable connection of tubes or similar components. The effect of the round tube and bolt system according to the invention is that movements in the longitudinal axis are blocked when connecting tubes with one another or tube-like components.

If, for example, two pipes as outer and inner pipes have form-fitting surfaces on the contact surfaces and have a common longitudinal axis, guide grooves are created on these surfaces 360 ° around the longitudinal axis in such a way that a cavity is created if they are congruent. The tube bar, which corresponds in shape and diameter to that of the cavity, is inserted into the cavity for a fixed or detachable connection.

The round tube bar for a permanent, non-detachable connection can be formed by active ingredients that are pressed into the cavity and fill it up to 100%.

The round tube latch for detachable connection can be formed from spring steel wire, hose material, solid rubber cord or balls made of metal, ceramic or glass, which correspond to the diameter of the cavity. The design of the round tube and bolt system according to the invention in connection with a round tube coupling piece is suitable for the fixed or detachable connection of tube ends with the same diameter and wall thickness.
