Abstract
The utility model discloses a kind of self-lubricating 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 base, casing wall and cylinder cap, the inside face of described casing wall has polytetrafluoroethylene lubricant coating, sliding connection between described piston and casing wall, the outside face of described piston rod has polytetrafluoroethylene lubricant coating, sliding connection between described piston rod and cylinder cap, the bottom of described base has a groove.By the way, the utility model is simple and reasonable, has self-lubricating property, and the impact by oil product lubricity is less.
Description
Technical field
The utility model relates to technical field of jacks, particularly relates to a kind of self-lubricating 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.
Hydraulic oil used in hydraulic jack, except to piston transferring energy, also plays the effect of lubrication, and under some particular surroundings, hydraulic pressure oil viscosity may increase, and lubricity reduces, and can not meet the lubricating requirement that jack normally works.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of self-lubricating jack, simple and reasonable, has self-lubricating property, and the impact by oil product lubricity is less.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of self-lubricating 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 base, casing wall and cylinder cap, the inside face of described casing wall has polytetrafluoroethylene lubricant coating, sliding connection between described piston and casing wall, the outside face of described piston rod has polytetrafluoroethylene lubricant coating, sliding connection between described piston rod and cylinder cap, the bottom of described base has a groove.
In the utility model preferred embodiment, the thickness of the polytetrafluorethylecoatings coatings on described casing wall inside face is 50 μm.
In the utility model preferred embodiment, the thickness of the polytetrafluorethylecoatings coatings on described piston rod outside face is 50 μm.
In the utility model preferred embodiment, described depth of groove is 4 millimeters.
The beneficial effects of the utility model are: the utility model self-lubricating jack, simple and reasonable, and have self-lubricating property, the impact by oil product lubricity is less.
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 self-lubricating 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, base, 5, casing wall, 6, cylinder cap.
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 self-lubricating 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 base 4, casing wall 5 and cylinder cap 6, the inside face of described casing wall 5 has polytetrafluoroethylene lubricant coating, sliding connection between described piston and casing wall, owing to having set up polytetrafluoroethylene lubricant coating on the inside face of casing wall 5, lubricity is better, reduces the dependence to oil product lubricity.
The outside face of described piston rod 3 has polytetrafluoroethylene lubricant coating, sliding connection between described piston rod 3 and cylinder cap 6, owing to having set up polytetrafluoroethylene lubricant coating on the outside face of piston rod 3, lubricity is better.
The bottom of described base 4 has a groove, and the degree of depth of described groove is 4 millimeters, be convenient to jack stroke inadequate time and steel pipe with the use of.
Preferably, the thickness of the polytetrafluorethylecoatings coatings on described casing wall 5 inside face is 50 μm.
Preferably, the thickness of the polytetrafluorethylecoatings coatings on described piston rod 3 outside face is 50 μm.
The beneficial effects of the utility model are: the utility model self-lubricating jack, simple and reasonable, and have self-lubricating property, the impact by oil product lubricity is less.
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.
