Abstract
A multi-stage jack cylinder comprises a cylinder cover, a cylinder housing, a cylinder chamber, a piston rod, a cylinder barrel, a steelwire retaining ring, an O-shaped ring, a retaining ring, a support ring, a seal ring, a pad, screws, trapezoidal threads, a key slot, a guiding key, a guide sleeve, a threaded sleeve and an oil hole, wherein two cylinder barrels are sequentially arranged on the circumference of one cylinder barrel on the circumference of the piston rod in the cylinder chamber, the inner circumference of the cylinder barrels correspond to the circumference of the cylinder barrel therein in shape and size, and the structure of the cylinder barrels correspond to that of the cylinder barrel in shape and size as well; the cylinder housing is arranged on the circumference of the outmost cylinder barrel in the cylinder chamber, the inner circumference of the cylinder housing corresponds to the size of the cylinder barrel, and the structure of the cylinder housing corresponds to that of the cylinder barrel in shape and size; and the cylinder cover is in threaded connection on the circumference at the left head of the cylinder housing. The multi-stage jack cylinder is suitable for airplane overhaul, and can lift an airplane to a height required by the overhaul and ground the airplane in a convenient, safe and reliable manner.
Description
Technical field
The utility model relates to a kind of mechanical device that weight is risen, especially the multistage jack cylinder that can rise aircraft.
Background technology
At present, known jack cylinder is the two-stage jack cylinder, and in the time of overhauling as aircraft, the insufficient height aircraft is risen can't overhaul aircraft.
Summary of the invention
In order to overcome the deficiency of existing jack cylinder, the utility model provides a kind of multistage jack cylinder, and it can rise the height that maintenance requires to aircraft.
The new solution that its technical matters that solves the utility model adopts is: by cylinder cap, cylinder shell, cylinder chamber, piston rod, cylinder barrel, elastic spring, O shape circle, back-up ring, support ring, seal ring, mat, screw, Acme thread, keyway, feather key, and the multistage jack cylinder that orienting sleeve, swivel nut, oilhole are formed.The cylinder barrel peripheral shape, the size that set gradually on the cylinder barrel periphery on the indoor piston rod periphery of cylinder in two interior Zhou Yuqi are corresponding, structure on the periphery is corresponding, the shape of structure, big or small corresponding, on the periphery with its in the cylinder barrel periphery on the corresponding cylinder barrel of structure, cylinder barrel peripheral shape in being provided with on the cylinder barrel periphery of the indoor outermost of cylinder in the Zhou Yuqi, big or small corresponding, structure on the periphery is corresponding, the shape of structure, the corresponding cylinder shell of size, and cylinder cap is threaded on the periphery of a cylinder shell left side.
The effect of covering of the present utility model is that it can rise the desired height of maintenance to aircraft, easily aircraft is overhauled.
