Abstract
The utility model relates to a piston rod of a piston cylinder, which comprises a tubular piston rod body, wherein a piston rod plunger and a piston rod column head are respectively arranged at the two ends of the piston rod body. The piston rod is characterized in that: threaded holes are arranged on the two ends of the piston rod body, and lower threaded holes are respectively arranged on the piston rod plunger and the piston rod column head corresponding respective upper threaded holes; and screws are respectively arranged on the two ends of the piston rod body and penetrate through the upper threaded holes to be matched with the lower threaded holes. The piston rod has the advantages that: the structure is simple, the installation is convenient, the bending resistant ability is strong, and the service life is long.
Description
Technical field
The utility model relates to a kind of piston rod, specifically, relates to a kind of piston cylinder piston rod.
Background technique
At present, the single action piston cylinder that the dump truck lifting is used, the two ends of the piston rod body of rod are respectively equipped with the piston rod column cap and the piston rod plunger of one.But this piston rod in use has piston rod bending deflection phenomenon, will have influence on piston cylinder and in a single day bending deflection appear in piston rod, and can cause scrapping of piston cylinder, causes waste.For this reason, the piston rod body of rod and piston rod column cap and piston rod plunger split-type structural have occurred, promptly piston rod column cap and piston rod plunger are fixed by welding on the piston rod, and means of fixation relatively wastes time and energy like this, and bending resistance is not fine.Therefore, need a kind of new technological scheme to solve above-mentioned technical problem.
The model utility content
The purpose of this utility model provides a kind of piston cylinder piston rod, and the resistance to bending of this piston rod is strong, long service life.
The technical solution adopted in the utility model is:
A kind of piston cylinder piston rod, comprise the tubular piston body of rod, the two ends of the described piston body of rod are respectively equipped with piston rod plunger and piston rod column cap, be provided with upper screwed hole on the two ends of the described piston body of rod, corresponding upper screwed hole separately is respectively equipped with down tapped hole on described piston rod plunger and the piston rod column cap, be respectively equipped with screw on the two ends of the described piston body of rod, described screw passes upper screwed hole and cooperates with following tapped hole.
Tapped hole was fixed on piston rod plunger and piston rod column cap on the piston rod body of rod about the utility model reached by screw, and this means of fixation not only simply is easy to install, and stability is fine, can improve the counter-bending ability of piston rod effectively.
The utility model has the advantages that: simple in structure, easy for installation, bending resistance is strong, long service life.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Wherein: 1, the piston body of rod, 2, the piston rod plunger, 3, the piston rod column cap, 4, upper screwed hole, 5, tapped hole down, 6, screw.
Embodiment
As shown in Figure 1: a kind of piston cylinder piston rod, comprise the tubular piston body of rod 1, be respectively equipped with piston rod plunger 2 and piston rod column cap 3 at the two ends of the piston body of rod 1, be provided with upper screwed hole 4 on the two ends of the piston body of rod 1, corresponding upper screwed hole 4 separately is respectively equipped with down tapped hole 5 on piston rod plunger 2 and the piston rod column cap 3, on the two ends of the piston body of rod 1, be respectively equipped with screw 6, screw 6 passes upper screwed hole 4 and cooperates with following tapped hole 5, piston rod plunger 2 and piston rod column cap 3 are fixed on the piston rod body of rod 1 by screw 6, this means of fixation not only simply is easy to install, and stability is fine, can improve the counter-bending ability of piston rod effectively.
