As it is shown in figure 1, this utility model provides a kind of swivel joint with high stability inner tube, including housing 1 He
Longitudinal inner tube 2, as shown in Figure 4, described housing 1 is coaxially provided with locking end 1-1 and support end 1-2, and described longitudinal inner tube 2 includes
Offer the locking mouth of pipe of internal thread hole, longitudinal inner tube 2 cylindrical offers the diameter the first ring less than the external diameter of longitudinal inner tube 2
Connected in star；Described support end 1-2 be provided with outside diameter outwardly, end diameter taper hole inwardly；Locking end 1-1 is provided with and interior
The through hole that pipe 2 cylindrical coordinates；Also include that half point ring 4, the cylindrical of described half point ring 4 are that the taper hole with support end 1-2 matches
The conical surface, endoporus is the through hole that the cylindrical with first annular groove matches；The described locking mouth of pipe is inserted through the taper hole of support end 1-2
Enter in the through hole of locking end 1-1, half point ring 4 hoop first annular groove and insert support end 1-2 taper hole in；Described locking
Offer the seal groove of annular in the through hole of end 1-1, in seal groove, be provided with sealing ring 9, described sealing ring 9 and institute in through hole
The outer surface of the longitudinal inner tube 2 stretched into is formed and is in sealing contact；Connecting on the internal thread hole of the locking mouth of pipe has the outer-hexagonal of hollow to lock
Jack panel 3, described external hexagonal locking nut 3 hexagonal stage portion laminating locking end 1-1 lateral surface by longitudinal direction inner tube along axle
To pretension；Described housing 1 is closely locked and is sealedly connected with tail-hood 10 on the end face of side, and described tail-hood 10 is provided with interior
The tail-hood hydraulic fluid port 101 that the endoporus of pipe 2 is connected.
By being fixed in locking end 1-1 of housing by longitudinal inner tube 2 axial tightening by external hexagonal locking nut 3, this is
First strong point, meanwhile, longitudinal inner tube to locking end 1-1 move axially its first annular groove will push half point ring 4 to
Move in the small end of the taper hole of support end 1-2, and then tighten up half point ring, so that half point ring endoporus banding is first annular recessed
Groove so that this position becomes second strong point, first strong point and second strong point certain distance so that two above is propped up
Support more efficient, more can increase the stability of device.
As in figure 2 it is shown, offer longitudinal inner tube spline half bore 6, locking end 1-1 on the end face of the described locking mouth of pipe vertically
