Abstract
The utility model relates to a dustproof hydraulic oil cylinder which comprises a cylinder barrel, a piston, a piston rod, a cylinder cover and a dustproof corrugated hose, wherein the piston is accommodated into the cylinder barrel and can reciprocate in the cylinder barrel; one end of the piston rod is fixedly connected with the piston; the other end of the piston rod extends out of the cylinder barrel; the cylinder cover is arranged at one end of the cylinder barrel; the dustproof corrugated hose is sleeved on the piston rod and can be stretched; one end of the dustproof corrugated hose is fixedly arranged on the piston rod; and the other end of the dust corrugated hose is fixedly arranged on the cylinder cover. According to the dustproof hydraulic oil cylinder disclosed by the utility model, the stretchable dustproof corrugated hose is sleeved on the piston rod, and thus dust can be prevented from falling on the piston rod, the wear to the piston rod is avoided and the service life of the hydraulic oil cylinder is prolonged.
Description
[technical field]
The utility model relates to a kind of hydraulic jack, is specifically related to a kind of dustproof hydraulic jack, belongs to the hydraulic equipment technical field.
[background technique]
Hydraulic jack is very widely industrial automation equipment of a kind of application, and it mainly is comprised of several parts such as cylinder barrel, piston and piston rods, makes piston to-and-fro motion in cylinder barrel by the piston rod pushing piston.
Yet the piston rod of the hydraulic jack of prior art is exposed outside, and it is easy to adhere to dust and oxidation, makes the piston rod plucking and causes wearing and tearing, leakage of oil, causes the working life of hydraulic jack shorter.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of structure improved dustproof hydraulic jack that has, to overcome described defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of this utility model is to provide a kind of dustproof hydraulic jack of simple in structure and good dustproof effect.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of dustproof hydraulic jack, and it comprises cylinder barrel, piston, piston rod, cylinder cap and dustproof corrugated flexible hose; Wherein, described piston is contained in the cylinder barrel, and can to-and-fro motion in cylinder barrel; Described piston rod one end and piston Joint, the other end extends outside the cylinder barrel; Described cylinder cap is arranged at an end of cylinder barrel; Described dustproof corrugated flexible hose is set on the piston rod and flexible, and the one end is fixed on the piston rod, and the other end is fixed on the cylinder cap.
Dustproof hydraulic jack of the present utility model further is set to: the end in described piston rod is provided with a connecting head.
Dustproof hydraulic jack of the present utility model also can be set to: be provided with a ceramic layer in the surface of described piston, and be provided with seal ring between cylinder barrel and piston.
Compared with prior art, the utlity model has following beneficial effect: dustproof hydraulic jack of the present utility model is by establishing retractable dustproof corrugated flexible hose at upper cover of piston rod, thereby dust can not fallen on the piston rod, thereby avoid the worn piston bar, prolonged the working life of hydraulic jack.
