Described cylinder assembly comprises cylinder block, cylinder block, cylinder piston rod and connector, one end of described cylinder block is hinged on one end that the first rotating shaft stretches out outside the first bearing, the other end of cylinder block is connected with one end of cylinder block, one end of cylinder piston rod is slidably connected in cylinder block, the other end is connected with connector, and connector is hinged on one end that the second rotating shaft stretches out outside the second bearing.
On the lateral wall of described cylinder block, position adjustable is connected with two electromagnetic induction blocks, lay respectively at the two ends of cylinder block length direction, and two electromagnetic induction blocks are all connected with controller for electric consumption by wire, the piston in described cylinder component is correspondingly provided with the magnet ring can responded to electromagnetic induction block.
Described cylinder assembly is two bar cylinders, and be connected with two cylinder piston rods in cylinder block, the free end of two cylinder piston rods is all connected with connector.
After adopting this structure, the utility model compared with prior art, has following advantage:
1) due to piston in cylinder component being provided with magnet ring, by the induction effect of magnet ring and electromagnetic induction block, the stroke of the piston in cylinder component is decided by the position of electromagnetic induction block on cylinder assembly completely, by the position of electromagnetic induction block, make piston in cylinder component can rest on the optional position in cylinder component in cylinder body, and the instant impact to oil circuit produced when there will not be piston movement on earth, avoid the damage of oil circuit and valve;
2) simultaneously, in order to prevent from occurring between piston end surface and cylinder seat end face in cylinder component and dead phenomenon, can by arranging the change in location of electromagnetic induction block on cylinder assembly, therefore, ensure that the further work of cylinder component, thus ensure that the action that forklift fork leg is protracted or fork leg is retracted is smooth and easy without hindrance;
3) after cylinder assembly adopts two bar cylinder, the thrust of cylinder piston rod is increased, application force required when being more applicable to the protracting and retract of the fork leg of forklift.
