Specific embodiment
With reference to embodiment, this utility model is further illustrated, following embodiments are illustrative, be not limited
It is impossible to limit protection domain of the present utility model with following embodiments.
A kind of rotatable telescopic hydraulic cylinder of piston rod, including a flexible cylinder barrel 2, is coated with piston rod in this flexible cylinder barrel
1, this piston rod front end is stretched out by a side end of flexible cylinder barrel, and the end side of this flexible cylinder barrel is installed with cylinder bottom 5,
By the back-end sealing of described piston rod in flexible cylinder barrel, innovation of the present utility model is this cylinder bottom, described cylinder bottom edge system
Go out a through hole 9, the piston rod rearward end para-position with this through hole homonymy is formed with a blind hole 10, pacify with a gear shaft 4 inside this blind hole
Dress, described piston rod can concentric with gear shaft rotate at the same speed, and the rearward end of this gear shaft is passed by the through hole that cylinder bottom is made, described
The rearward end of cylinder bottom, along being installed with a swing cylinder barrel 6 with flexible cylinder barrel vertical direction, is provided with a tooth in this swing cylinder barrel
Bar 7, the external tooth 8 that described tooth bar is made with the gear shaft rearward end outside cylinder bottom is meshed, described swing cylinder barrel two side ends
Portion is installed with a cylinder head respectively, and this two cylinder heads edge makes a hydraulic fluid port 3 respectively, the Hydraulic Station phase all with outside for the described hydraulic fluid port
Connection.
In the present embodiment, the blind hole edge that described piston rod is made is formed with spline 13, described tooth along piston rod bearing of trend
