Abstract
The utility model relates to an ejector pin, including an ejector pin centibar, its main characterized in that the ejector pin centibar constitute by upper and lower two parts, the upper portion pole of ejector pin centibar under be provided with a screw rod, its upper end is equipped with the contact bowl, ejector pin centibar lower part pole be equipped with a nut on, its lower extreme is equipped with a contact head. The utility model provides an ejector pin, when the engine at the during operation, ejector pin is because of using when having wearing and tearing, under the effort of the eccentric contact of lower part ejector pin's contact head, upper portion ejector pin and lower part ejector pin can rotation, the screw thread group that makes lower part ejector pin and upper portion ejector pin rolls out elongatedly each other, compensaties the clearance of wearing and tearing, makes the apneustic clearance of engine, can not send the noise, the melodized characteristics of work sound of messenger's engine.
Description
Technical field
The utility model relates to a kind of improved device of engine interior push rod, particularly relates to a kind of push rod.
Background technique
Push rod is a kind of a kind of parts for doing transferring power between the camshaft and valve rocker of internal-combustion engine being arranged on internal combustion engines, existing push rod is made up of steel pipe and upper and lower two contact heads, it can ceaselessly be worn and torn in use, once may wear to certain size, the gap of valve will become large, and the gap of valve becomes large, internal-combustion engine will be made operationally to send noise, the use the utility model affecting internal-combustion engine well solves existingly exists technical problem.
Summary of the invention
The utility model provides a kind of push rod, it mainly solves existing push rod and is made up of steel pipe and upper and lower two contact heads, it can ceaselessly be worn and torn in use, once may wear to certain size, the gap of valve will become large, and the gap of valve becomes large, internal-combustion engine will be made operationally to send the technical problem of noise.
A kind of push rod of the present utility model, comprise a push rod center-pole, be primarily characterized in that described push rod center-pole is made up of upper and lower two-part, the upper bar of described push rod center-pole is arranged with a screw rod, its upper end is provided with contact bowl, described push rod center-pole lower pole be provided with a nut, its lower end is provided with a contact head.
As preferably: described push rod center-pole upper bar and push rod center-pole lower pole connect into an entirety by bolt and nut.
As preferably: the central point of contact head of described push rod center-pole lower pole and the central point phase deviation of push rod, both eccentric designs.
The utility model provides a kind of push rod, when motor operationally, when there are wearing and tearing because using in push rod, under the active force that the bias of the contact head of bottom push rod contacts, top push rod and bottom push rod can rotate mutually, the thread set of bottom push rod and top push rod are produced mutually elongated, make up the gap of wearing and tearing, make the apneustic gap of motor, can not noise be sent, make the feature that the operational sound of motor is melodized.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Mark in figure: 1-push rod center-pole: 2-screw rod: 3-contacts bowl: 4-nut: 5-contact head.
Embodiment
