Description

Thin type hydraulic jack
Technical field
The utility model relates to technical field of jacks, particularly relates to a kind of Thin type 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.
Thin type hydraulic jack is that the one in hydraulic jack commonly uses kind, and existing Thin type hydraulic jack sealing property is bad, and toggle speed is slower.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of Thin type hydraulic jack, simple and reasonable, good seal performance, and toggle speed is very fast.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of Thin type hydraulic jack, comprise: hydraulic cylinder and the piston mandril cylinder being arranged on described hydraulic cylinder inside, the bottom of described piston mandril cylinder has the first groove, described first inside grooves has the first seal ring, described hydraulic cylinder inwall top has the second groove, described second inside grooves has the second seal ring, described hydraulic cylinder lower sides is while have oil inlet, described hydraulic cylinder lower sides another side has oil drain hole, the bottom of described piston mandril cylinder has an annular oblique angle oil-feed breach, the bottom of piston mandril cylinder is made to be trapezoidal.
In the utility model preferred embodiment, the height of described piston mandril cylinder is less than 5 centimetres.
In the utility model preferred embodiment, the outside face of described piston mandril cylinder has zinc-plated anti-corrosion layer.
The beneficial effects of the utility model are: the utility model Thin type hydraulic jack, simple and reasonable, good seal performance, and toggle speed is very fast.
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 Thin type hydraulic jack one preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, hydraulic cylinder, and 2, piston mandril cylinder, the 3, first seal ring, the 4, second seal ring, 5, annular oblique angle oil-feed breach.
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 Thin type hydraulic jack, comprise: hydraulic cylinder 1 and the piston mandril cylinder 2 being arranged on described hydraulic cylinder 1 inside, the bottom of described piston mandril cylinder 2 has the first groove, described first inside grooves has the first seal ring 3, described hydraulic cylinder inwall top has the second groove, described second inside grooves has the combination of the second seal ring 4, first seal ring 3 and the second seal ring 4, effectively improves the sealing property of jack.
Described hydraulic cylinder 1 lower sides is while have oil inlet, described hydraulic cylinder lower sides another side has oil drain hole, the bottom of described piston mandril cylinder 2 has an annular oblique angle oil-feed breach 5, the bottom of piston mandril cylinder is made to be trapezoidal, by annular oblique angle oil-feed breach 5, hydraulic oil easier by pressure transmission to piston mandril cylinder 2, jack start faster.
The height of described piston mandril cylinder 2 is less than 5 centimetres.
The outside face of described piston mandril cylinder 2 has zinc-plated anti-corrosion layer.
The beneficial effects of the utility model are: the utility model Thin type hydraulic jack, simple and reasonable, good seal performance, and toggle speed is very fast.
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.
