The heart is set, and diameter and height ecto-entad are gradually reduced.
It is preferred that, the height ratio of first buffer spring, the second buffer spring and the 3rd buffer spring is 3:2:1.
The novel hydraulic cylinder provided in the utility model, its cylinder body uses the heat radiation structure design of sandwich-type, in inside and outside wall
Between the first heat dissipating layer is set；First heat dissipating layer is tubular construction, and great contact area is respectively provided with inner and outer wall,
Can efficiently in wall friction produce heat import the first heat dissipating layer；Second heat dissipating layer nesting is arranged at around outer wall, and it leads to
Cross bolt tube two heat dissipating layers are fixed together with outer wall；The copper bolt tube of hollow-core construction can play heat conducting pipe simultaneously
Effect, the second heat dissipating layer outside heat importing timely accumulated on the first heat dissipating layer, improves radiating effect while fixed
Rate；Using above-mentioned heat dissipation design, it not only ensure that the high intensity of cylinder body but also improved hydraulic cylinder on the premise of cost is controlled
Radiating efficiency；By setting positioning strip on the piston rod, stability of the piston rod in motion process can be improved, reduces non-axle
Xiang Li, improves service life；By setting buffer unit in cavity bottom, and buffer unit be set to it is multiple highly different slow
Spring is rushed, piston understands contact successively and extrude the spring of different height, resistance of the spring for piston when close to bottom of chamber portion
Gradual increase；Both effectively prevented piston from being hit to cylinder body formation, but the effective piston that avoids slows down to piston rod suddenly
The stress caused, can be effectively protected cylinder body and piston rod, improve its service life.
