Through adopting above-mentioned technical scheme, when piston rod sliding fit is in the pneumatic cylinder, the oil pocket switch-on hydraulic oil of pneumatic cylinder, the oil pressure of hydraulic oil promotes the piston rod and outwards pushes up and stretch, this moment, the pole head of the body of rod is connected with the heavy object, heavy object self gravity produces the resistance to the body of rod and hydraulic oil produces the extrusion to the body of rod, make the middle part at the body of rod of the extrusion force that the body of rod both ends receives concentrate on the body of rod, therefore, be provided with the structural strength that the strengthening rib can effectively increase the body of rod at body of rod middle part, make the body of rod be difficult for taking place fracture and deformation, improve holistic fastness and life of piston rod, form the step shaft shape between two spliced poles.
The utility model discloses further set up to: the connecting end of the first connecting column and the rod body is provided with an arc-shaped piece, and the connecting end of the second connecting column and the rod body is also provided with an arc-shaped piece.
Through adopting above-mentioned technical scheme, the connection cross-section of spliced pole one, spliced pole two and the body of rod produces stress concentration phenomenon easily, reduces the intensity of the body of rod, so adopts the arc piece to pass through, reduces stress concentration, improves the overall structure intensity of the body of rod.
The utility model discloses further set up to: and a stress groove is formed in the connecting end of the first connecting column and the rod head along the circumferential direction of the first connecting column.
Through adopting above-mentioned technical scheme, reduce the stress concentration between pole head and the spliced pole one, prevent that the junction of pole head and spliced pole one from breaking.
The utility model discloses further set up to: the cross section of the second connecting column is in a regular trapezoid shape, and the area of the end face, far away from the rod body, of the second connecting column is smaller than that of the end face, connected with the rod body, of the second connecting column.
By adopting the technical scheme, the second connecting column is conveniently connected with the piston, the assembly time is reduced, and the working efficiency is improved.
The utility model discloses further set up to: the length of the first connecting column and the length of the second connecting column are both smaller than the length of the rod body.
By adopting the technical scheme, when the lengths of the first connecting column and the second connecting column are smaller than the length of the rod body, the extrusion force applied to the first connecting column and the second connecting column can be timely transmitted to the rod body, and the first connecting column and the second connecting column are prevented from being broken.
To sum up, the utility model discloses following beneficial effect has:
firstly, the whole structure of the piston rod has high strength, the phenomenon of stress concentration is not easy to occur, and the deformation resistance is good;
secondly, the structure is simple, and the manufacture and the assembly are easy;
thirdly, the service life is long.
