The utility model discloses a kind of hydraulic jack, comprise: hydraulic cylinder, the piston being arranged on described hydraulic cylinder inside and the piston rod be arranged on described piston, described hydraulic cylinder comprises casing wall and base plate, the diameter of described base plate is greater than the diameter of casing wall thus forms epitaxy part, described epitaxy part has multiple tapped bore, described base plate bottom also has a backing plate, described backing plate also has multiple tapped bore, described backing plate and base plate are bolted at epitaxy part place, and the middle part of described backing plate has a fit.By the way, the utility model is simple and reasonable, adds backing plate, can not cause damage during use to jack body.

Description

Hydraulic jack
Technical field
The utility model relates to technical field of jacks, particularly relates to a kind of hydraulic jack.
Background technology
Hydraulic jack, also known as oil jack, is that a kind of plunger or hydraulic actuating cylinder of adopting lifts the jack of part as rigid top, simple structure, lightweight, be easy to carry, conveniently moving.When jack uses in some field, the stroke of jack is inadequate, and bottom jack, usually increase steel pipe etc. support, when pressure is excessive, steel pipe is easy to cause damage to jack body.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of hydraulic jack, simple and reasonable, adds backing plate, can not cause damage during use to jack body.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of hydraulic jack, comprise: hydraulic cylinder, the piston being arranged on described hydraulic cylinder inside and the piston rod be arranged on described piston, described hydraulic cylinder comprises casing wall and base plate, the diameter of described base plate is greater than the diameter of casing wall thus forms epitaxy part, described epitaxy part has multiple tapped bore, described base plate bottom also has a backing plate, described backing plate also has multiple tapped bore, described backing plate and base plate are bolted at epitaxy part place, the middle part of described backing plate has a fit.
In the utility model preferred embodiment, the number of described tapped bore is 8 ~ 10.
In the utility model preferred embodiment, described epitaxy part length is diametrically 3 ~ 5 centimetres.
The beneficial effects of the utility model are: the hydraulic jack that the utility model discloses, simple and reasonable, add backing plate, can not cause damage during use to jack body.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model hydraulic jack one preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, hydraulic cylinder, and 2, piston, 3, piston rod, 4, casing wall, 5, base plate, 6, epitaxy part, 7, backing plate, 8, bolt.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of hydraulic jack, comprise: hydraulic cylinder 1, the piston 2 being arranged on described hydraulic cylinder 1 inside and the piston rod 3 be arranged on described piston 2, described hydraulic cylinder 1 comprises casing wall 4 and base plate 5, the diameter of described base plate 5 is greater than the diameter of casing wall thus forms epitaxy part 6, described epitaxy part 6 has multiple tapped bore, described base plate 5 bottom also has a backing plate 7, described backing plate 7 also has multiple tapped bore, described backing plate 7 is bolted at epitaxy part 6 place with base plate 5, like this when needs increase steel pipe to increase lifting stroke bottom jack, steel pipe would not cause damage to jack.
The middle part of described backing plate 7 has a fit, is convenient to better coordinate with steel pipe.
The number of described tapped bore is 8 ~ 10.
Described epitaxy part 6 length is diametrically 3 ~ 5 centimetres.
The beneficial effects of the utility model are: the hydraulic jack that the utility model discloses, simple and reasonable, add backing plate, can not cause damage during use to jack body.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
