Abstract
The invention discloses an acid-base-resistant and corrosion-resistant jack. The acid-base-resistant and corrosion-resistant jack comprises a jack hydraulic cylinder, a piston arranged inside the jack hydraulic cylinder and a piston rod arranged on the piston. A jack hydraulic cylinder outer zinc-plated layer is arranged on the external surface of the jack hydraulic cylinder, a jack hydraulic cylinder outer corrosion-resistant paint layer is further arranged on the external surface of the jack hydraulic cylinder outer zinc-plated layer, a piston rod inner zinc-plated layer is arranged on the external surface of the piston rod, a piston rod outer zinc-plated layer is arranged on the external surface of the inner zinc-plated layer on the piston, and a groove is formed in the bottom of the jack hydraulic cylinder. Through the mode, the acid-base-resistant and corrosion-resistant jack is simple and reasonable in structure, good in acid-base-resistance and corrosion-resistance performance and long in service life.
Description
Technical field
The present invention relates to technical field of jacks, particularly relate to a kind of acid and alkali-resistance withstanding corrosion 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.
Existing hydraulic jack decay resistance is bad, and jack supports use sometimes in a corrosive environment for a long time, reduces the service life of jack.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of acid and alkali-resistance withstanding corrosion jack, simple and reasonable, has preferably acid and alkali-resistance, decay resistance, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of acid and alkali-resistance withstanding corrosion jack, comprise: jack hydraulic cylinder body, the piston being arranged on described jack hydraulic cylinder body inside and the piston rod be arranged on described piston, the outside face of described jack hydraulic cylinder body has the external zinc coating of jack hydraulic cylinder, the outside face of the external zinc coating of described jack hydraulic cylinder also has the external withstanding corrosion coat of paint of jack hydraulic cylinder, the outside face of described piston rod has zinc coating in piston rod, on described piston in zinc coating outside face on there is piston rod external galvanized layer layer, the bottom of described jack hydraulic cylinder body has a groove.
In a preferred embodiment of the present invention, the thickness of the external zinc coating of described jack hydraulic cylinder is 55 μm.
In a preferred embodiment of the present invention, in described piston rod, the thickness of zinc coating and piston rod external galvanized layer layer is 60 μm.

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 acid and alkali-resistance withstanding corrosion jack one of the present invention preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, jack hydraulic cylinder body, and 2, piston, 3, piston rod.
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, the embodiment of the present invention comprises:
A kind of acid and alkali-resistance withstanding corrosion jack, comprise: jack hydraulic cylinder body 1, the piston 2 being arranged on described jack hydraulic cylinder body 1 inside and the piston rod 3 be arranged on described piston 2, the outside face of described jack hydraulic cylinder body 1 has the external zinc coating of jack hydraulic cylinder, the outside face of the external zinc coating of described jack hydraulic cylinder also has the external withstanding corrosion coat of paint of jack hydraulic cylinder, the combination of the external zinc coating of described jack hydraulic cylinder and the external withstanding corrosion coat of paint of jack hydraulic cylinder, the outer wall of jack hydraulic cylinder body is made to have good decay resistance.
The outside face of described piston rod 3 has zinc coating in piston rod; on described piston in zinc coating outside face on there is piston rod external galvanized layer layer; the combination of zinc coating and piston rod external galvanized layer layer in described piston rod; piston rod 3 is made to have good decay resistance; when piston rod 3 is stretched; during long-time support, piston rod 3 is played a very good protection.
The bottom of described jack hydraulic cylinder body 1 has a groove, can placing steel tubes etc. support in a groove when jack lifting insufficient height.
Preferably, the thickness of the external zinc coating of described jack hydraulic cylinder is 55 μm.
Preferably, in described piston rod, the thickness of zinc coating and piston rod external galvanized layer layer is 60 μm.
The invention has the beneficial effects as follows: acid and alkali-resistance withstanding corrosion jack of the present invention, simple and reasonable, there is preferably acid and alkali-resistance, decay resistance, long service life.
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.
