Abstract
The utility model discloses a hollow piston rod. The piston rod comprises a rod body, and is characterized in that a through hole penetrating through the rod body is formed in the rod body; one end of the rod body is a boss-shaped boss rod; one end of the boss rod is a section of threaded rod; a section of reamed hole is formed at the through hole at the end part of the threaded rod of the rod body; a round platform-shaped reamed hole is formed at the other end of the rod body; and a slot can also be arranged at the end part of the threaded rod. The hollow piston rod provided by the utility model has the advantages of simple structure and light weight, and cables can smoothly penetrate the through hole penetrating through the rod body, so as to facilitate the installation of a piston valve of an electrical appliance and other electrical elements, and the boss rod on the rod body can play the function of spacing, and the threaded rod can play the function of connecting the rod body and the piston.
Description
Technical field
The utility model relates to a kind of piston accessory technical field, especially a kind of hollow piston rod.
Background technique
The existing piston bar all is solid, and weight is heavier, so and owing to be that the solid elastic cable paper of wearing has become problem, be not suitable for installing electrical equipment piston valve and other electrical apparatus element, therefore be necessary to be improved.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure for the deficiency that solves above-mentioned technology existence, and weight is light, practical hollow piston rod.
To achieve these goals, the hollow piston rod of the utility model design comprises the body of rod, it is characterized in that a through hole that runs through the body of rod is arranged in the described body of rod, is a boss bar that is the boss shape at an end of the body of rod, and an end of boss bar is one section threaded stem.Through hole in the threaded stem end of the body of rod can be provided with one section reaming, is provided with a frustoconic shape reaming at the other end of the body of rod.Described threaded stem end also can be provided with groove.
The hollow piston rod that the utility model obtains is simple in structure, and weight is light.The through hole that runs through on the body of rod can be worn elastic cable paper smoothly, is convenient to install electrical equipment piston valve and other electrical apparatus element; Boss bar on the body of rod plays position-limiting action, and threaded stem plays the effect of connecting-rod body and piston; Elastic cable paper during by through hole reaming and frustoconic shape reaming play certain position-limiting action; The groove that the threaded stem end is set is the spacer groove that is used to install pad.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is the utility model one portion of end office (EO) structure for amplifying schematic representation.
Among the figure: the body of rod 1, through hole 2, boss bar 3, threaded stem 4, reaming 5, frustoconic shape reaming 6, groove 7.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment:
As shown in Figure 1, the hollow piston rod that present embodiment is described comprises the body of rod 1, and a through hole 2 that runs through the body of rod is arranged in the described body of rod 1, and through hole 2 can make elastic cable paper pass, and is convenient to install electrical equipment piston valve and other electrical apparatus element; End at the body of rod 1 is a boss bar 3 that is the boss shape, and an end of boss bar 3 is one section threaded stem 4.When the body of rod 1 was put into piston, threaded stem 4 played the effect of connecting-rod body 1 and piston, and boss bar 3 plays spacing effect; Through hole in threaded stem 4 ends of the body of rod 1 can be provided with one section reaming 5, is provided with a frustoconic shape reaming 6 at the other end of the body of rod 1.Reaming 5 and frustoconic shape reaming can both be played the effect that limits elastic cable paper; Described threaded stem 4 ends also can be provided with groove 7.Groove 7 can be used for installing seal ring, guarantees the sealing of piston rod and piston joint.
