Inclined lubricating oil diversion trench structure for improving lubrication of pin hole

The utility model provides an inclined lubricating oil diversion trench structure for improving lubrication of a pin hole. The inclined lubricating oil diversion trench structure comprises a piston, a piston pin, an oil outlet hole and a diversion trench, the piston pin is arranged in a pin hole of the piston, an included angle of 40-50 degrees is formed between the axis of the oil outlet hole and the axis of the piston, the oil outlet hole is formed in the upper portion of a piston inner cavity in the middle of the piston pin, the front end of the oil outlet hole is communicated with an inner cooling oil channel of the piston, and the flow guide groove is formed in the axial inner side edge of the pin hole. An included angle is formed between the axis of the flow guide groove and the axis of the pin hole. According to the piston pin seat, the pin seat hole flow guide grooves are additionally formed in the non-pressure-bearing middle-lower side, the left side and the right side, when engine oil flows to the p
