Abstract
A kind of jack with anti-wear function, comprise valve body, oil cylinder, folder cloth ring, piston ring, piston rod, seal ring, compared with prior art, this has the jack of anti-wear function, in oil cylinder, during oil-feed, piston ring up moves, folder cloth ring can be driven when piston ring up moves along with up moving, because folder cloth ring material is phenol resin, oil cylinder material is 45# steel, so folder cloth ring contacts as soft contact with cylinder wall, and there is the gap of 0.2-0.3mm in piston ring and oil cylinder inner wall, piston ring is avoided directly to contact with oil cylinder, thus can effectively avoid oil cylinder to damage.
Description
Technical field
This technology relates to a kind of jack, particularly relates to a kind of jack with anti-wear function.
Background technology
Traditional piston ring material is spheroidal graphite iron, and easy and oil cylinder produces frictional failure oil cylinder, in view of above-mentioned defect, is really necessary to design a kind of jack with anti-wear function.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of jack with anti-wear function, solves existing piston ring and easily scratches oil cylinder casing wall.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of jack with anti-wear function, comprise valve body, oil cylinder, folder cloth ring, piston ring, piston rod, seal ring, described oil cylinder is positioned at body top, described oil cylinder welds with valve body, described folder cloth ring is positioned at oil cylinder inner wall, described folder cloth ring is soft contact with oil cylinder inner wall, described piston ring is positioned at folder cloth ring inwall, described piston ring is connected with folder cloth ring close-fitting, described piston ring endoporus dress on the piston rod, gap between described piston ring external diameter and oil cylinder inner wall is 0.2-0.3mm.
Further, described folder cloth ring and piston ring bottom are also provided with seal ring.
Further, described seal ring and oil cylinder inner wall are interference fit.
Compared with prior art, this has the jack of anti-wear function, in oil cylinder, during oil-feed, piston ring up moves, folder cloth ring can be driven when piston ring up moves along with up moving, and because folder cloth ring material is phenol resin, oil cylinder material is 45# steel, so folder cloth ring contacts as soft contact with cylinder wall, and piston ring and oil cylinder inner wall exist the gap of 0.2-0.3mm, avoid piston ring directly to contact with oil cylinder, thus can effectively avoid oil cylinder to damage.
Accompanying drawing explanation

Valve body 1 oil cylinder 2
Folder cloth ring 3 piston ring 4
Piston rod 5 seal ring 401
Following detailed description of the invention will further illustrate in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
hereinafter, set forth multiple specific detail, to provide the thorough understanding to the concept forming described embodiment basis.But to one skilled in the art, embodiment described obviously can be put into practice when not have in these specific detail some or all.In other cases, well-known treatment step is not specifically described.
As shown in Figure 1, comprise valve body 1, oil cylinder 2, folder cloth ring 3, piston ring 4, piston rod 5, seal ring 401, described oil cylinder 2 is positioned at valve body 1 top, described oil cylinder 2 welds with valve body 1, described folder cloth ring 3 is positioned at oil cylinder 2 inwall, described folder cloth ring 3 is soft contact with oil cylinder 2 inwall, described piston ring 4 is positioned at folder cloth ring 3 inwall, described piston ring 4 is connected with folder cloth ring 3 close-fitting, described piston ring 4 endoporus is contained on piston rod 5, gap between described piston ring 4 external diameter and oil cylinder 2 inwall is 0.2-0.3mm, described folder cloth ring 3 and piston ring 4 bottom are also provided with seal ring 401, described seal ring 401 is interference fit with oil cylinder 2 inwall, this has the jack of anti-wear function, in oil cylinder 2, during oil-feed, piston ring 4 up moves, piston ring 4 can drive folder cloth ring 3 along with up moving when up moving, because folder cloth ring 3 material is phenol resin, oil cylinder 2 material is 45# steel, so folder cloth ring 3 is soft contact with oil cylinder 2 contact internal walls, and there is the gap of 0.2-0.3mm in piston ring 4 external diameter and oil cylinder 2 inwall, piston ring is avoided directly to contact with oil cylinder, thus can effectively avoid oil cylinder to damage, wherein valve body 1 supports fixation to oil cylinder 2, piston ring 4 is installation carriers of folder cloth ring 3 and seal ring 401, piston rod 5 is played a supporting role to foreign object, seal ring 401 is the leak tightnesss increasing folder cloth ring 3, effectively prevent hydraulic oil from penetrating folder cloth ring, thus lost efficacy when causing jack to work.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion made, all drop within protection domain of the present utility model.
