There is piston, the both ends of the protective jacket are respectively equipped with the ring-type location-plate set around piston bar body axis, the end cap and work
Plug removably be connected with the piston bar body, and is held and be provided with the side of cap and piston and ring-type positioning
The ring-type locating slot that plate is adapted, strip locating slot is further opened with the medial surface of the piston bar body, piston bar body
Support bar is provided with inner chamber, the surface of the support bar is provided with the strip location-plate being adapted to the strip locating slot.
Further, novel hollow piston rod of the present utility model, appearance is provided with the side of the end cap and piston
Put groove, be provided with internal thread on the medial surface of the storage tank, the both ends of the piston bar body respectively by screw thread with it is described
End cap connects with piston.
Further, novel hollow piston rod of the present utility model, the side of the piston, which is provided with, to be used to place sealing ring
Annular seal pocket and ring-type iron core slot for preventing magnet.
Further, novel hollow piston rod of the present utility model, the protective jacket are made up of stainless steel material.
Further, novel hollow piston rod of the present utility model, the surface of the end cap are provided with external screw thread.
Further, novel hollow piston rod of the present utility model, the ring-type location-plate and protective jacket are integrally formed.
By such scheme, the utility model at least has advantages below：Novel hollow piston rod of the present utility model, its
Piston bar body is the hollow steel pipe rolled by steel plate, therefore its consumptive material is more preferable, simultaneously because its surface is arranged with protection
Set, piston bar body are less likely to be damaged, and can directly change protective jacket after protective jacket loss, in addition piston bar body inner bracing piece
Setting so that the intensity of piston bar body is strengthened.In summary, novel hollow piston rod consumptive material of the present utility model compared with
Less and service life is longer.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
