Abstract
The utility model discloses a high-efficiency dust-proof hydraulic oil cylinder which comprises a cylinder body; a protective cover is fixedly arranged on the outer side of the cylinder body; a piston and a piston rod are arranged in the cylinder body; the piston and the piston rod are fixedly connected; both ends of the piston are respectively provided with an oil inlet and an oil outlet; the oil inlet and the oil outlet are communicated; a cylinder head and a cylinder tail are respectively arranged on both sides of the cylinder body fixedly; an oil inlet channel is arranged in the cylinder tail; and the oil inlet channel is communicated with the oil inlet in the piston. According to the high-efficiency dust-proof hydraulic oil cylinder, because the protective cover is arranged outside the cylinder body, impurities cannot enter the hydraulic oil cylinder, the piston rod is not damaged, and the service life of the hydraulic oil cylinder is prolonged; and meanwhile, because both ends of the piston are respectively provided with the oil inlet and the oil outlet, hydraulic oil flows from the oil inlet to the oil outlet, so that the braking time can be shortened, the braking reliability and sensitivity are effectively ensured, and popularization and use value is realized.
Description
Technical field
The utility model relates to the hydraulic jack field, particularly relates to a kind of efficient dustproof 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.
Existing hydraulic jack is in long-term using process; Impurity such as dust, water gets in the piston rod easily, damages oil sealing and piston rod, compares under the condition of severe at external environmental condition; Outside piston rod is directly exposed to; Be collided easily and damage, cause distortion, leakage of oil, the reliability and the sensitivity of braking are relatively poor.
The model utility content
The technical problem that the utility model mainly solves provides that braking is fast, sensitivity is high, the efficient dustproof hydraulic jack of good stability, good dustproof effect, long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of efficient dustproof hydraulic jack is provided, comprises cylinder body; The said cylinder body outside is fixed with protective housing; Be provided with piston and piston rod in the cylinder body, said piston is fixedly connected with piston rod, and said piston two ends offer filler opening and oil outlet respectively; Said filler opening is connected with oil outlet; The cylinder body both sides are fixed with cylinder head and cylinder tail respectively, are provided with oil inlet passage in the said cylinder tail, and said oil inlet passage is connected with filler opening on the piston.
In preferred embodiment of the utility model, said filler opening, oil outlet are respectively arranged with one-way valve.
In preferred embodiment of the utility model, said cylinder head, cylinder tail and protective housing are connected with cylinder body through fixed plate respectively.
In preferred embodiment of the utility model, be provided with guide sleeve between said cylinder head and the piston rod, offer 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.
The beneficial effect of the utility model is: the efficiently dustproof hydraulic jack of the utility model can prevent that impurity from getting in the hydraulic jack, avoids piston rod impaired because protective housing is set outside cylinder body; Prolonged the working life of this hydraulic jack, simultaneously, owing to offer filler opening and oil outlet respectively at the piston two ends; Hydraulic oil flows to oil outlet from filler opening; Can shorten period of braking, guarantee the reliability and the sensitivity of braking effectively, have popularizing value.
Description of drawings
Fig. 1 is the efficiently perspective view of dustproof hydraulic jack one preferred embodiment of the utility model;
The mark of each parts is following in the accompanying drawing: 1, cylinder body, 2, protective housing, 3, piston, 4, piston rod, 5, filler opening, 6, oil outlet, 7, cylinder head, 8, the cylinder tail, 9, oil inlet passage, 10, fixed plate, 11, guide sleeve, 12, oil discharge passage.
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 efficient dustproof hydraulic jack comprises cylinder body 1, and said cylinder body 1 outside is fixed with protective housing 2; Be provided with piston 3 and piston rod 4 in the cylinder body 1, said piston 3 is fixedly connected with piston rod 4, and said piston 3 two ends offer filler opening 5 and oil outlet 6 respectively; Said filler opening 5 is connected with oil outlet 6; Cylinder body 1 both sides are fixed with cylinder head 7 and cylinder tail 8 respectively, are provided with oil inlet passage 9 in the said cylinder tail 8, and said oil inlet passage 9 is connected with filler opening 5 on the piston 3.
Said filler opening 5, oil outlet 6 are respectively arranged with one-way valve, and under external force, hydraulic oil can flow to oil outlet 6 rapidly from the filler opening 5 of piston 3, has shortened period of braking, has accelerated draining speed.
Said cylinder head 7, cylinder tail 8 and protective housing 2 are connected with cylinder body 1 through fixed plate 10 respectively, compact structure, and installation is firm, convenient disassembly.
Be provided with guide sleeve 11 between said cylinder head 7 and the piston rod 4; Offer some oil discharge passages 12 on the said guide sleeve 11; Be provided with some gasket seals between said guide sleeve 11 and the piston rod 4,, can in time discharge compressed high-pressure oil gas along with the slide relative of piston rod 4 with guide sleeve 11; Thereby reduce the speed fluctuation of piston rod 4, improved the stable of this hydraulic jack operation greatly.
Add man-hour, hydraulic oil gets into from the oil inlet passage of cylinder tail 89, and the filler opening 5 through piston 3 flows to oil outlet 6 rapidly; Thereby shortened period of braking; Accelerated draining speed, simultaneously, the oil discharge passage 12 on the guide sleeve 11 can be emitted the high-pressure oil gas that piston rod 4 produces in moving process; Reduced the frictional force of piston rod 4, thereby improved the stability of piston rod 4 with guide sleeve 11.
Compared with prior art, the efficiently dustproof hydraulic jack of the utility model can prevent that impurity from getting in the hydraulic jack because protective housing 2 is set outside cylinder body; Avoid piston rod 4 impaired, prolonged the working life of this hydraulic jack, simultaneously; Owing to offer filler opening 5 and oil outlet 6 respectively at piston 3 two ends, hydraulic oil flows to oil outlet 6 from filler opening 5, can shorten period of braking; Guarantee the reliability and the sensitivity of braking effectively, had popularizing value.
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.
