Using being threadedly coupled between cylinder barrel and end cap, it is provided between cylinder cap and self-locking cylinder barrel, self-locking cylinder barrel and cylinder barrel, cylinder barrel and end cap
Cylinder barrel sealing ring；Cylinder cap sealing ring and guide sleeve are installed between described cylinder cap and described piston rod；Set in self-locking cylinder barrel
Be equipped with the self-locking spring and self-locking bearing pin of two compositions 180 arrangement, self-locking spring be pressed on self-locking bearing pin and self-locking inner wall of cylinder it
Between；Piston packing is installed between piston and inner wall of cylinder；Piston rod one end is connected through a screw thread with clamp nut, piston
Piston rod packing circle is installed between bar and piston.
Preferably, piston packing uses y-shaped ring, remaining described sealing ring all uses O-ring seals.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention by be provided with self-locking cylinder barrel, self-locking spring,
Self-locking grooves are provided with self-locking bearing pin, piston rod, when piston rod reaches certain position, the self-locking bearing pin compressed by self-locking spring
Snap onto in piston rod self-locking grooves, hydraulic cylinder realizes mechanical self-latching；When needing unblock, high-voltage oil liquid on self-locking cylinder barrel by opening
Some open keyholes, extrude self-locking bearing pin compression face, and when hydraulic coupling is more than spring force, self-locking bearing pin is retracted, and hydraulic cylinder realizes solution
Lock.
