Abstract
The invention discloses a hydraulic jack which comprises a hydraulic cylinder body, a piston and a piston rod, wherein the piston is arranged inside the hydraulic cylinder body; the piston rod is arranged on the piston; the hydraulic cylinder body comprises a bottom plate; the thickness of the bottom plate is 2.5-3 cm; a circular groove is formed in the middle of the bottom plate; the depth of the circular groove is 0.5-0.6 cm. By adopting the mode, the hydraulic jack is simple and reasonable in structure, and due to adoption of the groove in the bottom, a steel tube is convenient and relatively stable to place.
Description
Technical field
The present invention relates to technical field of jacks, particularly relate 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.
Summary of the invention
The technical matters that the present invention 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 present invention 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 a preferred embodiment of the present invention, described circular groove is coaxial with base plate.
In a preferred embodiment of the present invention, the thickness of described base plate is 2.7 centimetres.
In a preferred embodiment of the present invention, the degree of depth of described groove is 0.55 centimetre.
The invention has the beneficial effects as follows: hydraulic jack of the present invention, 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 embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, 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 hydraulic jack one of the present invention 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 embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention 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 invention has the beneficial effects as follows: hydraulic jack of the present invention, simple and reasonable, bottom has groove, is convenient to placing steel tubes, more stable.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention 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 invention.
Claims (4)
