Technical field
The present invention relates to technical field of hydraulic oil cylinder, particularly relate to a kind of Novel hydraulic cylinder.
Background technology
As everyone knows, hydraulic jack is a kind of hydraulic energy to be converted to mechanical energy to reach the device of machine driving object, is widely used in mechanical field, existing hydraulic jack, generally include cylinder body, piston and piston rod, hydraulic oil flows into and flows out to promote piston and moves back and forth in cylinder body in cylinder body, piston rod is connected on piston, in order to reduce friction, the diameter of piston rod is less than the diameter of piston conventionally, in use, inventor finds that the axle center of piston rod easily departs from the axle center of cylinder body under Action of Gravity Field, because making gas, the reciprocating motion of piston ceaselessly passes in and out the piston side of cylinder body simultaneously, the gas that comprises impurity is entered in cylinder body under this wobbler action, the pollution of this impurity not only will increase the frictional force of piston movement, the all parts simultaneously easily wearing and tearing in cylinder body, reduce service life, increase plant maintenance number of times.
Summary of the invention
For solving the problems of the technologies described above, the invention provides one and effectively prevent that piston rod axle center from departing from, airborne impurity is difficult for entering cylinder body, increases service life, reduces the Novel hydraulic cylinder of plant maintenance number of times.
Novel hydraulic cylinder of the present invention, comprise cylinder body, piston and piston rod, also comprise locating ring group, described locating ring group is fixed on described cylinder body inner piston rod one side, described locating ring group comprises fixing outer shroud, bearing inner ring and support bar, described fixing outer shroud is fixed on the inwall of described cylinder body, and described bearing inner ring is sleeved on described piston rod, and the two ends of described support bar are fixedly connected on respectively on described fixing outer shroud and bearing inner ring; The end of described cylinder body is provided with axis hole, air inlet and gas outlet, and described air inlet and gas outlet are respectively arranged with air inlet check valve and gas outlet check valve, is also provided with filter on described air inlet; On described cylinder body, be positioned at axis hole place and be disposed with from the inside to the outside elastic seal ring and covering with paint or varnish, described in the root covered with paint or varnish be also provided with annular impurity groove.
Further, described fixing outer shroud is threaded connection the inwall that is fixed on described cylinder body, is provided with the first block for supporting described fixing outer shroud on the inwall of described cylinder body.
Further, in described cylinder body, be also provided with the annular gland for limiting described fixing outer shroud relative displacement.
Further, described bearing inner ring is ring in ball bearing.
Further, described support bar is multiple, and described support bar is symmetrically distributed between described fixing outer shroud and the top of bearing inner ring and between bottom.
Further, the top of described impurity groove is provided with annular impurity enclosing cover, is also provided with the second block for fixing described impurity enclosing cover on the inwall of described impurity groove.
Further, the diameter of described air inlet is greater than the diameter of described gas outlet.
Compared with prior art beneficial effect of the present invention is: comprise cylinder body, piston and piston rod, also comprise locating ring group, locating ring group is fixed on cylinder body inner piston rod one side, locating ring group comprises fixing outer shroud, bearing inner ring and support bar, fixing outer shroud is fixed on the inwall of cylinder body, bearing inner ring is sleeved on piston rod, and the two ends of support bar are fixedly connected on respectively on fixing outer shroud and bearing inner ring; The end of cylinder body is provided with axis hole, air inlet and gas outlet, and air inlet and gas outlet are respectively arranged with air inlet check valve and gas outlet check valve, is also provided with filter on air inlet; On cylinder body, be positioned at axis hole place and be disposed with from the inside to the outside elastic seal ring and cover with paint or varnish, the root of covering with paint or varnish is also provided with annular impurity groove; Like this, can effectively ensure that by locating ring group the axle center of piston rod is not offset, can excessively not increase frictional force simultaneously, air inlet and gas outlet can ensure the inlet and outlet of gas and cylinder body effectively, air inlet being separated to setting with gas outlet is because intake velocity is conventionally not identical with the speed of giving vent to anger, too fast intake velocity will cause filter to be difficult to effective filtered air, and the diameter of air inlet is greater than the diameter of gas outlet conventionally; Cover with paint or varnish the sliding capability that has not only ensured piston rod, automatically lubricating oil is added on piston rod and bearing inner ring on, can brush the impurity on lower piston rod simultaneously, impurity will be brushed to impurity groove, is convenient to cleaning.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail. Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
