Hydraulic coupling with freely regulated coupling direction

Abstract

The invention discloses a hydraulic pipe joint capable of freely adjusting connecting directions. The joint comprises two sets of hollow bolts, two revolving bodies and a plurality of combined seal rings. The coaxial direction and the radial direction of the hollow bolts are all provided with an oil path channel; the revolving bodies are provided with a through hole along the direction of a rotating shaft; the vertical direction is provided with a bypass hydraulic fluid port with an inner thread; the hollow bolts penetrate from the through hole; the two ends of the through hole are sealed by a combined seal gasket; the hollow bolts, the revolving bodies and the combined seal gasket form a hinged joint; the revolving bodies can revolve along the hollow bolts by 360 degrees; and the outer thread of the hollow bolt II is connected with the inner thread of the revolving body I. As the revolving body I can revolve by 360 degrees and the revolving body II can revolve by 360 degrees opposite to the revolving body I, the hydraulic fluid port of the revolving body II can be led to face to any direction by adjusting the revolving corners of the two revolving bodies; therefore, the hydraulic pipe joint is very easy to be jointed with a metal pipe or a hydraulic hose, thus being capable of achieving the goals of optimizing the direction of the metal pipe and leading the hydraulic hose to be reasonably bent.

Description

technical field [0001] The invention relates to a hydraulic pipeline system, in particular to a hydraulic pipe joint whose connection direction can be adjusted arbitrarily. Background technique [0002] A variety of pipe joints are often used in hydraulic piping systems, among which there are rotary joints and welded articulated pipe joints that can adjust the direction. These two joints can only adjust the direction in the two-dimensional plane, and cannot The direction can be adjusted arbitrarily in the space. Therefore, under some special space conditions, when these pipe joints are used to connect metal pipes or hydraulic hoses, it will cause difficulties in docking, especially for hydraulic hoses, and sometimes it is easy to cause the hose to twist or bend. The radius is too small, which will affect the service life of the hose.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a new type of hydraulic pipe joint. This pipe joint can adjust the connection direction arbitrarily, making it easier to connect with metal pipes or hydraulic hoses, and can conveniently realize reasonable bending of the hose, avoiding twisting of the hose. Problems such as too small bending radius
