Description
Technical field
This utility model belongs to oil cylinder apparatus technical field, particularly relates to the piston rod of a kind of upper leveling cyclinder.
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.
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; improve the wearability of cylinder bearing; also make bearing pin effectively be lubricated and protect simultaneously; extending the life-span of bearing pin, improve work efficiency, reduce the piston rod of the upper leveling cyclinder of production cost, its technical scheme is as follows:
The piston rod of upper leveling cyclinder, it is characterized in that, one end of the piston rod of described upper leveling cyclinder is connected with head by bearing pin, the end of the other end of piston rod is provided with saddle, described saddle can slide along the inboard wall of cylinder block of oil cylinder under the drive of piston rod, one end of saddle is provided with plush copper, and plush copper and inboard wall of cylinder block form fuel-displaced groove; Piston rod is provided with retractable dustproof set, and one end of retractable dustproof set is fixedly installed on piston rod, and when piston rod is when cylinder body activity, retractable dustproof set can be stretched or shrink.
Optimal way is, described head and the junction of piston rod are provided with fibre bush.
Optimal way is, between described retractable dustproof set and piston rod, place is provided with fibre bush.
The piston rod of the upper leveling cyclinder that this utility model provides, when in use, piston rod exsertion part installs a telescopic dirt-proof boot additional, has both improved the presentation quality of oil cylinder, also makes piston rod expose extending area simultaneously and is effectively protected.
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 retractable dustproof set of this utility model and piston rod, place is provided with fibre bush. So that retractable dustproof set can be better setting on the piston rod so that it is more good that retractable dustproof is enclosed within the sealing property between cylinder body and piston rod exposed parts.
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, improve the wearability of cylinder bearing, also make bearing pin effectively be lubricated and protect simultaneously; extend the life-span of bearing pin, improve work efficiency, reduce production cost.
