[0002] The crankshaft connecting rod mechanism is an important configuration part in the crankcase structure. In the existing crankcase connecting rod mechanism, the structure in which the counterweight is connected to the gear is generally used. The crankcase with this structure is in the high-speed operation process of the crankcase. It is easy to generate a large frictional resistance in the middle, resulting in poor operation of the crankshaft and connecting rod, frequent impact loads on the crankshaft and connecting rod, severe wear and tear of the crankshaft and connecting rod, resulting in excessive temperature rise of the crankshaft and connecting rod, broken rods and even burning shafts, etc. Phenomenon
In addition, during the working process of the crankshaft, the lubrication of the piston rod pin connecting the connecting rod and the piston rod has an important impact on the overall performance of the engine. However, in the existing structure, the lubrication conditions of the piston rod pin are always poor, and it is difficult to meet the needs.
In addition, due to the complex structure, large demand for compressed air, and the integration of the connecting rod and the piston rod, it is easy to cause problems such as fracture due to insufficient structural strength.

The invention relates to a crankshaft connecting rod mechanism with small frictional resistance and connection not prone to break between a connecting rod and a piston rod. The crankshaft connecting rod mechanism comprises a connecting rod and a crankshaft connecting tank, wherein the upper end of the connecting rod is rotatably connected to the lower end of the piston rod; the crankshaft connecting cover comprises a crankshaft connecting upper cover and a crankshaft connecting lower cover below the crankshaft connecting upper cover; the crankshaft connecting upper cover and the crankshaft connecting lower cover are detachably connected; one end of the bottom of the crankshaft connecting lower cover extends in a downwards inclined manner to form an oil throwing block, and the crankshaft connecting lower cover and the oil throwing block are an integrated structure; a connecting rod oil storage slot is formed in the peripheral direction of the inner wall of the groove in the upper end of the connecting rod, oil holes are respectively formed n two side walls of the groove; oil end of each oil hole is communicated with the oil storage slot, the other end of each oil hole is communicated with a first pin hole. The crankshaft connecting rod mechanism can be used for solving the problems of easy fracture and the like due to insufficient structural strength as the structure is complex, quantity demanded quantity of the compressed air is relatively great, and the connecting rod and the piston rod are integrated in the prior art.
