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.Jack is when some field (as construction trade) uses, and the stroke of jack is inadequate, and usually bottom jack, increase steel pipe support, at present, the bottom of this jack is unfavorable for placing steel tubes, uses instability.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of hydraulic jack, simple and reasonable, and bottom has groove, is convenient to placing steel tubes, more stable.
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 a base plate, the thickness of described base plate is 2.5 ~ 3 centimetres, the middle part of described base plate has a circular groove, and the degree of depth of described circular groove is 0.5 ~ 0.6 centimetre.
In the utility model preferred embodiment, described circular groove is coaxial with base plate.
In the utility model preferred embodiment, the thickness of described base plate is 2.7 centimetres.
In the utility model preferred embodiment, the degree of depth of described groove is 0.55 centimetre.
The beneficial effects of the utility model are: the utility model hydraulic jack, and simple and reasonable, bottom has groove, is convenient to placing steel tubes, more stable.
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;
Fig. 2 is the upward view of Fig. 1.
In accompanying drawing, the mark of each parts is as follows: 1, hydraulic cylinder, and 2, piston, 3, piston rod, 4, base plate, 5, circular groove.
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 and Fig. 2, 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 a base plate 4, the thickness of described base plate 4 is 2.5 ~ 3 centimetres, the middle part of described base plate 4 has a circular groove 5, the degree of depth of described circular groove is 0.5 ~ 0.6 centimetre, when the lifting stroke of jack is inadequate, need when bottom it, placing steel tubes increases lifting stroke, then the end of steel pipe is placed in circular groove 5, makes supporting construction more stable like this.
Described circular groove 5 is coaxial with base plate 4.
The thickness of described base plate 4 is 2.7 centimetres.
The degree of depth of described groove 5 is 0.55 centimetre.
The beneficial effects of the utility model are: the utility model hydraulic jack, and simple and reasonable, bottom has groove, is convenient to placing steel tubes, more stable.
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.
