Abstract
The utility model discloses a stable hydraulic oil cylinder. The stable hydraulic oil cylinder comprises a cylinder body, wherein a piston and a piston rod are arranged inside the cylinder body; the piston is fixedly connected with the piston rod; a cylinder head and a cylinder tail are fixed at two ends of the cylinder body respectively; an air bleeding device is arranged on the cylinder body; the air bleeding device is communicated with an inner cavity of the cylinder body; a guide sleeve is arranged between the cylinder head and the piston rod; and a plurality of oil outlet passages are formed on the guide sleeve. The air bleeding device is arranged on the cylinder body, so that the stable hydraulic oil cylinder is simple in structure and convenient to maintain and oil pipelines are simplified; meanwhile, as the guide sleeve is arranged between the cylinder head and the piston rod, the oil outlet passages are formed on the guide sleeve, and along relative sliding of the piston rod and the guide sleeve, compressed high-pressure oil gas can be exhausted in time, so that speed fluctuation of the piston rod is reduced and the running stability of the hydraulic oil cylinder is greatly improved.
Description
Technical field
The utility model relates to a kind of stable type hydraulic jack.
Background technique
Hydraulic jack with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is used widely in the hydraulic system of various machineries.
Yet existing hydraulic jack oil circuit pipeline line structure more complicated, installing/dismounting is inconvenient, and the less stable during the piston rod operation.
The model utility content
The technical problem that the utility model mainly solves provides a kind of simple in structure, easy installation and removal, be easy to safeguard, the stable type hydraulic jack of efficient stable.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of stable type hydraulic jack is provided, comprises cylinder body; Be provided with piston and piston rod in the said cylinder body, said piston is fixedly connected with piston rod, and the cylinder body two ends are fixed with cylinder head and cylinder tail respectively; Said cylinder body is provided with means of deflation; Said means of deflation communicates with inner chamber of cylinder block, is provided with guide sleeve between said cylinder head and the piston rod, offers some oil discharge passages on the said guide sleeve.
In preferred embodiment of the utility model, be provided with some gasket seals between said guide sleeve and the piston rod.
In preferred embodiment of the utility model, be provided with filter screen in the said means of deflation.
In preferred embodiment of the utility model, said cylinder head, cylinder tail are fixedly connected with cylinder body through screw respectively.
In preferred embodiment of the utility model, said piston rod end is connected with hangs head.
The beneficial effect of the utility model is: the utility model stable type hydraulic jack is owing on cylinder body, being provided with means of deflation, and is simple in structure, simplified the oil circuit pipeline; Be convenient to safeguard, owing between cylinder head and piston rod, be provided with guide sleeve, offer some oil discharge passages on the guide sleeve simultaneously; Slide relative along with piston rod and guide sleeve; Can in time discharge compressed high-pressure oil gas, thereby reduce the speed fluctuation of piston rod, improve the stable of this hydraulic jack operation greatly.
Description of drawings
Fig. 1 is the perspective view of the utility model stable type hydraulic jack one preferred embodiment;
The mark of each parts is following in the accompanying drawing: 1, cylinder body, 2, piston, 3, piston rod, 4, cylinder head, 5, the cylinder tail, 6, means of deflation, 7, guide sleeve, 8, oil discharge passage, 9, hang head.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model is embodiment comprise:
A kind of stable type hydraulic jack comprises cylinder body 1, is provided with piston 2 and piston rod 3 in the said cylinder body 1; Said piston 2 is fixedly connected with piston rod 3; Cylinder body 1 two ends are fixed with cylinder head 4 and cylinder tail 5 respectively, and said cylinder body 1 is provided with means of deflation 6, and said means of deflation 6 communicates with cylinder body 1 inner chamber; Be provided with guide sleeve 7 between said cylinder head 4 and the piston rod 3, offer some oil discharge passages 8 on the said guide sleeve 7.
Be provided with some gasket seals between said guide sleeve 7 and the piston rod 3, can prevent hydraulic fluid leak, play good sealing effect.
Be provided with filter screen in the said means of deflation 6, can prevent that hydraulic jack from getting into impurity when venting.
Said cylinder head 4, cylinder tail 5 are fixedly connected with cylinder body 1 through screw respectively, easy installation and removal, and good fixing effect is convenient to maintenance.
Said piston rod 3 ends are connected with hangs 9.
Add man-hour; The gas of cylinder body 1 inner chamber is overflowed through the means of deflation 6 that is arranged on the cylinder body 1; Simultaneously; Oil discharge passage 8 on the guide sleeve 7 can be emitted the high-pressure oil gas that piston rod 3 produces in moving process, reduced the frictional force of piston rod 3 with guide sleeve 7, thereby has improved the stability of piston rod 3.
Compared with prior art, the utility model stable type hydraulic jack is owing on cylinder body, being provided with means of deflation 6, and is simple in structure; Simplified the oil circuit pipeline, be convenient to safeguard, simultaneously owing between cylinder head 4 and piston rod 3, be provided with guide sleeve 7; Offer some oil discharge passages 8 on the guide sleeve 7,, can in time discharge compressed high-pressure oil gas along with the slide relative of piston rod 3 with guide sleeve 7; Thereby reduce the speed fluctuation of piston rod 3, improved the stable of this hydraulic jack operation greatly.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
