Description

A kind of novel hydraulic cylinder
Technical field
The present invention relates to a kind of hydraulic cylinder, more particularly to a kind of novel hydraulic cylinder.
Background technology
Hydraulic cylinder is a kind of critical elements being widely used in modern industry Hydraulic Industry, particularly performs member in straight line Part field, hydraulic cylinder plays the status of ruler always.It completes plant equipment and is expected what is realized as executive component In function, its work process, action is extended and retracted according to hydraulic cylinder piston rod, certain function is reached.
Under many operating modes, it is necessary to which piston rod steady operation is in current location after hydraulic cylinder piston rod stretches out, it can neither stretch Going out to retract, i.e., usually said self-locking, on conventional art, in order to realize this function, be all to lean on hydraulicdirectional control valve Median Function realizes self-locking or uses hydraulic lock, but is due to the leakage of valve, and self-locking effect is not ideal enough, or even in lifting In the large-scale engineering machineries such as machine, excavator, it may appear that engineering accident.
The content of the invention
In order to solve this problem, the present invention proposes a kind of novel hydraulic cylinder.Technical scheme is as follows:
A kind of novel hydraulic cylinder, by piston rod, cylinder cap sealing ring, guide sleeve, cylinder cap, cylinder barrel sealing ring, self-locking cylinder barrel, self-locking bullet Spring, self-locking bearing pin, cylinder barrel, piston packing, piston rod packing circle, piston, clamp nut and end cap composition;Described self-locking cylinder Open keyhole is provided with cylinder;Self-locking grooves are provided with described piston rod;Described cylinder cap and self-locking cylinder barrel, self-locking cylinder barrel and cylinder barrel, 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.
