Background
The piston is a reciprocating element in the cylinder body of the automobile engine. The basic structure of the piston can be divided into a crown, a crown and a skirt. The piston crown is the main part that makes up the combustion chamber and its shape is related to the combustion chamber form chosen. The gasoline engine mostly adopts a flat-top piston, and has the advantage of small heat absorption area. The top of the piston of a diesel engine often has various pits, the specific shape, position and size of which must be adapted to the requirements of the mixture formation and combustion of the diesel engine.
At present, lubricating oil is smeared in the installation of a kinematic pair formed by a pin and a connecting rod before working, and the kinematic pair has no lubricating oil channel, can only be lubricated by a splashed oil film in the working process in an auxiliary mode and cannot be effectively and continuously lubricated, and the kinematic pair further causes the abrasion of the pin and the connecting rod under the motion conditions of high speed, high temperature and high load, so that the service life of parts is shortened.

The utility model aims to provide a: in order to solve the above problems, a continuously lubricating piston mechanism is proposed.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a piston mechanism capable of continuously lubricating comprises a piston head, an oil ring and a piston skirt, wherein an oil hole channel is formed in an inner cavity of the piston head and communicated with an oil return hole, a pin is inserted into the piston skirt, an arc-shaped groove is formed in the outer wall of the pin, a connecting rod is rotatably connected to the outer wall of the pin, and an oil inlet hole is formed in the top of the connecting rod.
As a further description of the above technical solution:
the arc-shaped groove is of an arc-shaped structure.
As a further description of the above technical solution:
an annular groove is formed in the inner surface wall of the connecting rod, and the annular groove is communicated with the oil inlet hole.
As a further description of the above technical solution:
the oil inlet hole corresponds to the bottom of the oil hole channel in the vertical direction.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
