Turn, to improve efficiency, and avoid damage to the efficient hydraulic cylinder of sealing structure.
The purpose of this utility model can be realized by following technical proposal：A kind of efficient hydraulic cylinder, including cylinder barrel, cylinder barrel
It is interior to be provided with the push rod for being fixed with and being stretched out from cylinder barrel front end on piston, and piston, it is characterised in that：Also include the circle parallel with push rod
Shaft-like locating rod, described locating rod is located in cylinder barrel, and two ends are connected with cylinder barrel two ends respectively, and described piston is provided with circle
Poroid positioning hole, and locating rod sets through positioning hole, or described positioning rod rear end is connected with piston, and locating rod front end from
Cylinder barrel front end is stretched out.
This hydraulic cylinder additionally sets locating rod to be positioned, and is avoided that in push rod telescopic process along itself axial deflection, with
Operating efficiency is improved, and does not change push rod seal structure, and locating rod is round bar shape, therefore sealing property is unaffected, and tool
There are two kinds of structures, can be selected according to actual needs.
In a kind of above-mentioned efficient hydraulic cylinder, the locating rod front end and push rod wall stretched out from cylinder barrel front end pass through fixation
Part is fixed.
In a kind of above-mentioned efficient hydraulic cylinder, described fixture includes the fixed cover of two diameter parallels, and two
Connected between fixed cover by fixing pipe, and two fixed covers distinguish fixed cover on locating rod bar wall and push rod wall, it is fixed
Set, push rod and locating rod are provided with the fixing hole connected with fixed inside pipe wall, in addition to sequentially pass through fixing hole and fixing pipe, and
End is bolted with the bolt of nut.
Therefore intensity can be strengthened using push rod after stabilization easy to connect, and the stretching of locating rod front end.
In a kind of above-mentioned efficient hydraulic cylinder, described positioning hole hole wall is provided with and the sealed sealing ring of locating rod.
Compared with prior art, the utility model has the following advantages that：
This hydraulic cylinder additionally sets locating rod to be positioned, and is avoided that in push rod telescopic process along itself axial deflection, with
Operating efficiency is improved, and does not change push rod seal structure, and locating rod is round bar shape, therefore sealing property is unaffected, and tool
There are two kinds of structures, can be selected according to actual needs.
