Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, it is impossible to
Protection scope of the present invention is limited with following embodiment.
A kind of rotatable telescopic hydraulic cylinder of piston rod, stretches cylinder barrel 2 including one, is coated with piston rod 1 in this flexible cylinder barrel, should
Piston rod front end is stretched out by a side end of the cylinder barrel that stretches, and the end side of this flexible cylinder barrel is installed with cylinder bottom 5, this cylinder
By the back-end sealing of described piston rod in flexible cylinder barrel, the innovation of the present invention is at the end, and described cylinder bottom edge makes a through hole 9,
Piston rod rearward end para-position with this through hole homonymy is shaped with a blind hole 10, installs with a gear shaft 4, described piston inside this blind hole
Bar can synchronized rotation concentric with gear shaft, the through hole that the rearward end of this gear shaft is made by cylinder bottom passes, the rearward end of described cylinder bottom
Along being installed with a swing cylinder barrel 6 with flexible cylinder barrel vertical direction, a tooth bar 7 is installed in this swing cylinder barrel, described tooth bar with
Being positioned at the external tooth 8 that the gear shaft rearward end outside cylinder bottom makes to be meshed, described swing cylinder barrel two-side-ends part is not installed with
One cylinder head, this two cylinder heads edge makes a hydraulic fluid port 3 respectively, and described hydraulic fluid port is all connected with outside Hydraulic Station.
In the present embodiment, the blind hole edge that described piston rod is made is shaped with spline 13 along piston rod bearing of trend, before described gear shaft
End is shaped with the keyway 14 being meshed with described spline.
In the present embodiment, for providing buffering to the contact process of tooth bar with cylinder head, it is positioned at the two of two cylinder head 11 homonymies at described tooth bar
