Problems solved by technology
[0003] In view of this, the object of the present invention is to provide a straight-through joint with a spline-locked circumferential degree of freedom. The inner and outer splines on the lock sleeve are respectively matched with the outer splines of the joint and the inner splines of the joint assembly. When piping, it is not necessary to use a wrench to fix the joint to prevent the joint from rotating, which solves the problem that it is difficult to disassemble in a narrow space

Embodiment Construction
[0020] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0021] figure 2 It shows a schematic diagram of the disassembled structure of the spline-locked straight-through joint provided by the present invention, including the joint body 1 and the lock sleeve 3. The outer surface of the middle part of the joint body 1 is provided with a joint outer flower along the axial direction of the joint body 1. Key 5, the inner wall of the lock sleeve 3 is provided with the lock sleeve inner spline 10 that cooperates with the joint outer spline 5, the outer surface of the lock sleeve 3 is provided with the lock sleeve outer spline 9, and the outside of the lock sleeve 3 is provided with the outer spline of the lock sleeve. The assembled internal spline 13 that the spline 9 cooperates; The assembled internal spline 13 can be directly processed on the device that needs to be installed with the j...

The invention discloses a straight connector with a degree of freedom in the circumferential direction locked by a spline, and relates to the field of pipeline connectors. The straight connector comprises a connector body and a lock sleeve. A connector external spline is arranged on the outer surface of the middle of the connector body, a lock sleeve internal spline which is matched with the connector external spline is arranged on the inner wall of the lock sleeve, a lock sleeve external spline is arranged on the outer surface of the lock sleeve, an assembly internal spline which is matched with the lock sleeve external spline is arranged outside the lock sleeve, a disassembling groove is formed in a position along the circumferential direction of the outer surface of the lock sleeve, and the connector external spline is in clearance fit with the lock sleeve internal spline. The straight connector with the degree of freedom in the circumferential direction locked by the spline has the advantages that a connector mounting hole, the lock sleeve and the connector body are locked in a spline connection form, accordingly, wrenches for clamping the straight connector can be omitted when external guide pipes are about to be tightened or disassembled, the straight connector is convenient to operate and is safe and reliable, influence on sealing between the connector body and the connector mounting hole when external pipelines are about to be tightened or disassembled can be prevented, and the straight connector is suitable to be mounted in narrow places.
Description
technical field [0001] The invention relates to the field of pipeline joints, in particular to a straight-through joint with a spline locking the degree of freedom in the circumferential direction. Background technique [0002] The connection between the main body and the pipeline in each hydraulic system of the existing aircraft mostly adopts the screw-in straight-through pipe joint HB4-8-2002, the screw-in variable-diameter straight-through pipe joint HB4-9-2002, and the A-type screw-in straight-through pipe joint HB5986 ~5988-2008, HB5989~5991-2008 screw-in variable diameter straight-through pipe joints are connected with the main body, and the sealing form adopts the threaded connection sealing form of HB4-59-1987. This connection method must use a wrench to tighten the hexagonal position of the screw-in straight-through and variable-diameter straight-through pipe joints when tightening, especially disassembling, and at the same time use another wrench to tighten / disasse...
