Embodiment Construction

[0013] like figure 1 As shown, the embodiment of the present invention consists of a welded hinged pipe joint 1 , a transition joint 2 , and a welded hinged pipe joint 2 3 . The welded articulated pipe joint 1 has an axial oil port 11 and a radial oil port 12, and the radial oil port 12 is welded with the transition joint 2. The structure of transition joint 2 is as follows figure 2 As shown, there is a straight threaded hole, both ends are flat, and one end is chamfered to facilitate welding. The welded joint 2 3 has an axial oil port 31 and a radial oil port 32 , and the axial oil port 31 is connected with the transition joint 2 . Since both welded articulated pipe joints can rotate freely around themselves 360 degrees, and the rotary motion of welded articulated pipe joint two is always perpendicular to the rotary motion of welded articulated pipe joint one, the two vertical rotary motions can make the oil port 11 and the oil port 32 have any spatial angle, that is to s...

Abstract

The invention discloses a design of a universal hydraulic pipe joint. The designed joint comprises two welding type hinged pipe joints with the standard number of JB/T978-1977 and the transition joint of the direct type pipe of an inner thread; wherein the transition joint is welded with the radial opening of the welding type hinged pipe joint I; the welding type hinged pipe joint II is connected with the transition joint; both the two welding type hinged pipe joints can freely revolve by 360 degrees along the self body; the revolving motion of the welding type hinged pipe joint II is still vertical to the revolving motion of the welding type hinged pipe joint I; and the hydraulic fluid port of the joint II can be led to obtain a feel space direction by adjusting the revolving angles of the two joints. The universal hydraulic pipe joint designed by the invention leads a metal pipe or a hydraulic hose to be easily jointed, can optimize the direction of the metal pipe, leads the hydraulic hose to be reasonably bent, and avoids the problem of causing the distortion of the hose. As a standard element and the transition joint with simple structure are employed, the universal hydraulic pipe joint is simple to be manufactured and has low cost.

Description

technical field [0001] The invention relates to a hydraulic pipeline system, in particular to the design of a universal hydraulic pipe joint. Background technique [0002] A variety of pipe joints are often used in hydraulic piping systems. Among them, there are rotary joints and welded hinged joints that can adjust the direction. Both of these joints can only adjust the direction in the two-dimensional plane, but cannot be adjusted in three The direction can be adjusted arbitrarily in the space, so under some special space conditions, when using these pipe joints to connect with metal pipes or hydraulic hoses, it will cause difficulties in docking, especially for hydraulic hoses, sometimes it is easy to cause the hose to be twisted or bent. If the radius is too small, the service life of the hose will be affected. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a design of a universal hydraulic pipe joint, which...
