Problems solved by technology
But the disadvantage is that after long-term work and wear on both sides of the cylinder and the piston, the piston and the middle part of the cylinder wall are easily worn into an ellipse, and the sealing effect is getting worse, which will cause a decrease in power and increase in fuel consumption. The increase in exhaust emissions also causes adverse factors such as pollution to the environment

Embodiment Construction
[0009] In the figure, an anti-eccentric wear piston is characterized in that the piston is composed of a sealing plug 1 and a guide tube 2, a fork-shaped connecting rod 3 is arranged between the sealing plug 1 and the guiding tube 2, and the fork-shaped connecting rod 3 is two Connecting holes 4 are provided at the ends, and piston pins 5 and pin holes 6 are respectively provided on the sealing plug 1 and the guide tube 2. When assembling, install the lower end of the fork-shaped connecting rod 3 in the guide tube 2, connect it with the piston pin 5, then set the sealing plug 1 on the upper end of the fork-shaped connecting rod 3, and connect it with the piston pin 5.

The invention discloses an anti-eccentric wear piston, which is characterized by consisting of a sealing plug and a guide pipe, wherein a fork-shaped connecting rod is arranged between the sealing plug and the guide pipe; the two ends of the fork-shaped connecting rod are provided with connecting holes respectively; and the sealing plug and the guide pipe are provided with a piston pin and a pin hole respectively. During assembly, the lower end of the fork-shaped connecting rod is arranged in the guide pipe and connected through the piston pin and the sealing plug is sleeved at the upper end of the fork-shaped connecting rod and connected through the piston pin. The anti-eccentric wear piston has the advantages that: the fork-shaped connecting rod is arranged between the sealing plug and the guide pipe and eccentric wear ellipses are not formed on the piston and both sides of a cylinder wall during the long-term working process of an engine, so that the service life of the engine is prolonged, energy sources are saved and waste gas emission is reduced.
Description
Technical field: [0001] The invention relates to a piston used in a cylinder of an engine, in particular to an anti-eccentric wear piston. Background technique: [0002] At present, known engine cylinder is made up of cylinder, piston, piston pin. It is characterized by simple structure and convenient maintenance. But the disadvantage is that after long-term work and wear on both sides of the cylinder and the piston, the piston and the middle part of the cylinder wall are easily worn into an ellipse, and the sealing effect is getting worse, which will cause a decrease in power and increase in fuel consumption. The increase in exhaust emissions also causes adverse factors such as pollution to the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide an anti-eccentric wear piston with simple structure and convenient use. [0004] The technical...
