Problems solved by technology
However, the traditional valve ejector rods are all cast in one piece and lack some protective devices to stabilize the valve ejector rods. When the valve ejector rods are subjected to high stress, they tend to shake or deform and break. The traditional valve ejector rods do not have corresponding protection. device to protect, it is easy to break and damage

The invention discloses a valve ejector rod reinforced through spring strip fixing seats. The valve ejector rod comprises an ejector rod body and the spring strip fixing seats. One end of the ejector rod body is provided with an ejector pin. The other end of the ejector rod body is provided with an ejector cap. The ejector rod body is provided with an external thread. Lantern ring seats are arranged on the spring strip fixing seats. Internal threads are arranged on the inner side walls of the lantern ring seats. The lantern ring seats are in threaded connection with the external thread through the internal threads to be connected to the ejector rod body. The ejector rod body is provided with at least two spring strip fixing seats. The upper ends and the lower ends of the spring strip fixing seats are provided with spring strip fixing tables. Tension spring bodies are arranged between the spring strip fixing tables. By means of the manner, the valve ejector rod can be machined, the situation that the valve ejector rod vibrates and deforms when bearing larger stress is avoided, and the service life of the valve ejector rod is prolonged.
Description
technical field [0001] The invention relates to the field of valve push rods, in particular to a valve push rod reinforced with a spring bar fixing seat. Background technique [0002] The valve ejector rod is a device that transmits the thrust of the ejector rod to the rocker arm to drive the valve to open. The upper and lower ends of the push rod are heat-treated and polished to improve wear resistance. There are two types of shafts: solid and hollow. One end of the push rod is in contact with the cam, and the other end is in contact with the valve. Its function is to transmit the thrust of the cam to the valve. However, the traditional valve ejector rods are all cast in one piece and lack some protective devices to stabilize the valve ejector rods. When the valve ejector rods are subjected to high stress, they tend to shake or deform and break. The traditional valve ejector rods do not have corresponding protection. device to protect, it is easy to break and damage. Co...
