Abstract
The utility model relates to a bulb type piston rod, which comprises a piston rod body (1). The piston rod body (1) is configured to be spherical (2) at one end; a neck part (3) is disposed between a spherical head (2) and the piston rod body (1); the neck part (3) is a cylinder with a diameter smaller than that of the piston rod body (1), and the other end of the piston rod body (1) is configured as a spiral riveting end (4).The structure of the piston rod realizes simple connection between the piston rod and the cylinder head and flexible direction change, increases the quality of the piston rod, reduces installation and maintenance of the piston rod, is rational in structure design, and has long service life.
Description
Technical field
The utility model relates to a kind of automobile piston rod, and a particularly a kind of end of piston rod body is set to the bulb formula piston rod of bulb formula.
Background technique
At present, automobile mostly is the body of rod of any surface finish greatly with piston rod, one end of the body of rod is processed as the riveting end, the other end is processed as threaded end, threaded end is connected with cylinder head, for being threaded, when cylinder body is in heavy load, be subjected to force direction complexity and ambient temperature height, many water, under the heavy operating conditions of dust, phenomenons such as cylinder head connecting thread stripped thread or corrosion be stuck usually occur, the connection part fault of cylinder head and piston rod is increased, simultaneously when handling the cylinder body job failure, adopt thread connecting mode, the dismounting between its cylinder body and the mechanical transmission gudgeon extremely bothers, especially in narrow and small working site, dismounting space, difficulty is big especially for maintenance cylinder body fault, length consuming time.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of can the realization to be connected with cylinder head fast, and the bulb formula piston rod that can use for a long time.
The technical solution of the utility model is: a kind of bulb formula piston rod, comprise the piston rod body, one end of described piston rod body is set to sphere, be provided with neck between spherical head and the piston rod body, described neck is the cylindrical body of diameter less than the piston rod body, and the other end of piston rod body is set to revolve the riveting end.
Preferably: the described riveting end that revolves is the cylindrical body of diameter less than the piston rod body.
Preferably: described piston rod body is set to taper near the position of neck.
Preferably: described piston rod body is set to taper near the position of revolving the riveting end.
The beneficial effects of the utility model are: the structure of the utility model piston rod makes the Placement between piston rod and the cylinder head simple, and can turn flexibly, can improve the quality of piston rod, reduce the installation maintenance process of piston rod, reasonable in design, long service life.
