Technical field
The utility model is related to industrial technical field, more particularly to a kind of hydraulic cylinder.
Background technology
Hydraulic cylinder be hydraulic energy is changed into mechanical energy, the hydraulic pressure that does straight reciprocating motion (or oscillating motion) performs member
Part.Its simple in construction, reliable operation.Realized with it during reciprocating motion, deceleration device can be removed from, and without drive gap,
Stable movement, therefore be used widely in various mechanical hydraulic systems.Hydraulic cylinder power output and piston effective area and
The pressure difference on its both sides is directly proportional；Hydraulic cylinder substantially by cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit with
Exhaust dressPutComposition.Buffer unit is with exhaust apparatus depending on concrete application occasion, and other devices are then essential.
According to the structure type of conventional hydraulic cylinder, three types can be classified as：The structure of the hydraulic cylinder of environmental sanitation refuse vehicle
Form is varied, and its sorting technique also has a variety of：It can be divided into straight reciprocating motion formula and gyroscopic pendulum dynamic formula by motion mode；Press
It can be divided into single-acting formula, double-acting type by action of hydraulic force situation；It can be divided into piston type, plunger type, multistage by structure type to stretch
Contract telescopic, pinion and-rack etc.；It can be divided into pull bar, earrings, footing, hinge etc. by installation form；Pressing force grade can be divided into
16Mpa, 25Mpa, 31.5Mpa etc..
Existing hydraulic cylinder structure is complicated, and sealing is poor, using easily being leaked after a period of time, influences hydraulic cylinder
Service life.
Utility model content
The purpose of this utility model is that there is provided a kind of hydraulic cylinder in order to overcome the deficiencies in the prior art.
The utility model is to be achieved through the following technical solutions：
Cylinder cap is provided with a kind of hydraulic cylinder, including cylinder barrel, the cylinder barrel side, is provided between the cylinder barrel and cylinder cap
Several lock-screws, the cylinder cap center is provided with inlet opening, and the cylinder barrel opposite side is provided with closure, described close
Capping is connected with end cap, and the cylinder barrel is internally provided with piston rod, and described piston rod one end is connected with piston, the end cap and work
Sealant is provided between stopper rod, sealing gasket is provided between the closure and cylinder barrel, is set between the piston and cylinder barrel
Have and corrosion-resistant coating is provided with two sealing rings, the piston end surface, locking spring is provided between the piston and piston rod
With locking nut.
It is to inlay connection as optimal technical scheme of the present utility model, between the sealing gasket and closure.
As optimal technical scheme of the present utility model, the corrosion-resistant coating uniform fold is on piston end surface, and thickness
For 0.3mm~1.2mm.
As optimal technical scheme of the present utility model, the locking spring is with covering on the piston rod.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, close by setting
Sealing, sealing gasket, sealing ring, corrosion-resistant coating and locking spring, so in use, hydraulic cylinder is in sealant, sealing gasket, sealing ring
In the presence of there is preferable sealing, the service life of effective extension hydraulic cylinder, and corrosion-resistant coating can avoid piston
Corrosion, while locking spring can realize the stable installation of piston.
