Cylinder body, is provided with expansion link in the middle part of described cylinder seat, be provided with spring inside described expansion link, and described inner chamber of cylinder block is provided with piston, described
Piston lower portion is provided with Glais ring, and described piston bottom Middle face is provided with blind hole, and described piston base is provided with bumper ring, described piston top
Portion is provided with piston rod, and described cylinder body top is provided with fairlead.
Preferably, described oil-feed props up mouth at least provided with two groups, and is evenly distributed on around expansion link.
Preferably, described expansion link is the structure that upper shank diameter slightly descends that shank diameter is thin, and the top of expansion link upper boom is circle
Bench-type.
Preferably, few 1cm to the 2cm of described blind hole aspect ratio expansion link height, described blind hole diameter is more straight than expansion link upper boom
Big 0.5cm to the 1cm in footpath.
Technique effect of the present utility model and advantage: this shock resistance long-life forklift lifting oil cylinder, hydraulic oil is from oil-in
Entering oil cylinder, prop up mouth by oil-feed and flow to inner chamber of cylinder block, hydraulic oil promotes piston piston rod jack-up to be worked, and piston lower portion is provided with
Glais ring hydraulic oil can be made to reveal piston seal；When the piston is moving down, first expansion link supports piston,
Making piston slow down, expansion link upper boom is set to circular platform type, even if oil cylinder occurs vibration that blind hole also can be made to be inserted in expansion link accurately, lives
It is additionally provided with bumper ring bottom plug, further reduces the impulsive force of piston；Therefore this utility model is reasonable in design, it is possible to extend
In the service life of oil cylinder, there is social utility and be worth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: mouth, 4 cylinder bodies, 5 expansion links, 6 pistons, 7 Glais rings, 8 blind holes, 9 bufferings are propped up in 1 cylinder seat, 2 oil-ins, 3 oil-feeds
