Description
Technical field
This utility model belongs to oil cylinder apparatus technical field, particularly relates to the piston rod mechanism of a kind of upper amplitude oil cylinder.
Background technology
Current state inner cylinder dress valve is all first weld a valve seat on cylinder body, then valve is arranged on valve seat to realize turnover oil and hydraulic control; Mesohigh cylinder tube material is generally adopted No. 45 seamless pipes, higher running into rated operating pressure, when cylinder barrel wall thickness is inadequate, to thicken cylinder barrel wall thickness for main path, but also results in oil cylinder own wt simultaneously and lays particular stress on, and cost is increased. When in use, piston rod is when cylinder interior activity, and piston rod has part when passing in and out cylinder body, has exposed parts for current oil cylinder, and after using for a long time, the exposed parts of piston rod can have damage in atmosphere due to exposure. After the long-time use of oil cylinder, each junction of oil cylinder can be worn and torn comparatively serious, thus having a strong impact on the use time of oil cylinder. And, current oil cylinder piston rod in the process used can be deviate from from cylinder interior, or in use piston rod and the interphase interaction of inner sleeve stoping piston rod to be deviate from cylinder body, after using a period of time, make inner sleeve unstable with the connection of cylinder body, thus piston rod can be made to deviate from cylinder body, affect the use time.
Summary of the invention
The purpose of this utility model is in that to solve techniques discussed above problem; there is provided one to make piston rod expose extending area to be effectively protected; improve the presentation quality of oil cylinder; also make bearing pin effectively be lubricated and protect simultaneously; extend the life-span of bearing pin; the piston rod mechanism of the upper amplitude oil cylinder that improve work efficiency, reduce production cost, can well prevent piston rod from deviating from from cylinder interior, its technical scheme is as follows:
The piston rod mechanism of upper amplitude oil cylinder, including piston rod, it is characterized in that, one end of described piston rod is connected with head by bearing pin, the end of the other end of piston rod is provided with saddle, described saddle can slide in cylinder body along inboard wall of cylinder block under the drive of piston rod, and one end of saddle is provided with plush copper, and plush copper forms oil-feed groove with inboard wall of cylinder block, described piston rod is provided with sliding outer cover, described sliding outer cover is fixedly installed on the exposed parts of piston rod, described sliding outer cover is connected with retractable dustproof set, one end of retractable dustproof set is fixedly installed on sliding outer cover, the other end of retractable dustproof set is fixed on the outer wall of cylinder body, along with stretching out of piston rod, retractable dustproof set can be stretched for closing the piston rod portion being stretched and expose outside cylinder body, the outer wall of described sliding outer cover is provided with a ring-shaped clip locking groove, described ring-shaped clip locking groove is possible to prevent piston rod to come off from cylinder interior.
Optimal way is, described head and the junction of piston rod are provided with fibre bush.
Optimal way is, between described saddle and inboard wall of cylinder block, place is provided with fibre bush.
The piston rod mechanism of the upper amplitude oil cylinder that this utility model provides, when in use, oil-feed groove facilitates the oil in oil pipe to enter into cylinder interior. And saddle can play the effect of sealing so that piston rod can be promoted after cylinder interior oil-feed to move. The Main Function of retractable dustproof set is the presentation quality both having improved oil cylinder, also makes piston rod expose extending area simultaneously and is effectively protected. Sliding outer cover and ring-shaped clip locking groove are mainly used for the stop to piston rod and use; can well prevent piston rod from deviating from from cylinder interior; piston rod moves it is also possible that need not carry out clashing into laggard whereabouts with the inner sleeve of cylinder body; piston rod and cylinder body can well be protected, extend its use time.
The further head of this utility model is worn pin shaft hole position and is installed fibre bush, improves the wearability of cylinder bearing, also makes bearing pin effectively be lubricated and protect simultaneously, extends the life-span of bearing pin.
Between the further saddle of this utility model and inboard wall of cylinder block, place is provided with fibre bush. So that saddle can be better contact with inboard wall of cylinder block so that the sealing property between saddle and inboard wall of cylinder block is more good. The wearability of saddle can be improved, extend the use time.
This utility model adopts the welding of integrated balanced valve, it is not necessary to valve seat and valve partial installation, improves work efficiency, reduces production cost.
The beneficial effects of the utility model are: make piston rod expose extending area and be effectively protected; improve the presentation quality of oil cylinder; also make bearing pin effectively be lubricated and protect simultaneously; extend the life-span of bearing pin, improve work efficiency, reduce production cost, can well prevent piston rod from deviating from from cylinder interior.
