[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 and connecting rod mechanism small in frication resistance in the movement process. The crankshaft and connecting rod mechanism comprises a connecting rod and a crankshaft connecting box, wherein the upper end of the connecting rod is connected with the lower end of a piston rod rotationally; a crankshaft connecting cover comprises a crankshaft connecting upper cover and a crankshaft connecting lower cover located under the crankshaft connecting upper cover, the crankshaft connecting upper cover is detachably connected with the crankshaft connecting lower cover, one end of the bottom of the crankshaft connecting lower cover extends obliquely downwards to form an oil leak block, and the crankshaft connecting lower cover and the oil leak block are of an integrated structure; a connecting rod oil storage groove is formed in the inner wall of a groove in the upper end of the connecting rod in the peripheral direction, the two lateral walls of the groove are each provided with an oil hole, one end of each oil hole is communicated with the connecting rod oil storage groove, and the other end of each oil hole is communicated with a first pin hole. The crankshaft and connecting rod mechanism small in frication resistance in the movement process resolves the problems in the prior art that as the structure is complex, the demand for compressed air is large, and a connecting rod and a piston rod are integrated, the structural strength is poor, and then fracture is easily caused.
