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.
The novel hydraulic cylinder of a kind of piston rod energy rotational lock, the innovation of the present invention is, including locking cylinder barrel 3 and a rotation
Cylinder barrel 5, a side end of this locking cylinder barrel and rotating sleeve is fixedly mounted by a cylinder bottom 4, the opposite side of described rotating sleeve
End is provided with a cylinder head 2, is coated with a side end of a piston rod 1 in this cylinder head, and the end side of piston rod passes cylinder
The end, is also passed by described rotating sleeve, and the integrally formed piston of this piston rod 17 is positioned at the inner side of described cylinder head, the two of this piston
The cavity that cylinder head and rotating sleeve are internally formed is divided into two sealing cavitys by side end face, cylinder head and rotating cylinder in this two annular seal spaces body
Making the first hydraulic fluid port 8 and the second hydraulic fluid port 7 respectively in cylinder sidewall, described piston rod is positioned at the end outer rim of rotating sleeve and is set with
One latching ram 15, the cavity rotated in cylinder head is separated by this latching ram, and wherein side cavity and the second hydraulic fluid port are connected, separately
Being shaped with one the 3rd hydraulic fluid port 6 at described rotating sleeve sidewall correspondence position in the cavity of side, described piston rod outer rim is provided with one can be with
The locking device that described latching ram is fixing, this piston rod is positioned at the end of rotating sleeve and is provided with and can match with described rotating sleeve
The rotary apparatus closed.
