Description

Technical Field

[0002] In the industrial field, air compressors, as common power equipment, are widely used in machinery manufacturing, chemical industry, metallurgy, mining and other industries, and undertake important functions such as gas compression, transportation and storage.

[0003] Lubricating oil is required during the operation of air compressors, especially piston cylinders. Lubricating oil can form an oil film between the piston and the cylinder to reduce direct contact, thereby reducing friction and wear. In addition, during the compression process, the piston generates heat, and the lubricating oil can absorb and take away the heat to prevent the piston from overheating. In the prior art, the splashing effect generated by the rotation of the crankshaft is usually used to splash and disperse the lubricating oil onto the piston and the cylinder wall, resulting in uneven distribution of the lubricating oil on the cylinder wall and easy waste of lubricating oil.

A vertically arranged mounting sleeve 36 is fixed in the cylinder 11, and the oil inlet pipe 34 is inserted in the mounting sleeve 36. The oil inlet pipe 34 slides with the mounting sleeve 36 in the vertical direction, and a connecting pipe 37 is connected between the bottom of the oil barrel 2 and the bottom of the mounting sleeve 36.

[0037] When the oil inlet pipe 34 moves downward in the mounting sleeve 36, the lubricating oil in the mounting sleeve 36 enters the oil injection pipe 31 under the squeezing action of the oil inlet pipe 34, and then a proper amount of lubricating oil is sprayed on the inner wall of the cylinder 11 through the nozzle 33, so that the lubricating oil is evenly distributed on the inner wall of the cylinder 11. At the same time, the pressure plate 4 moves downward under the action of its own gravity and the elastic force of the pressure spring 41, so that the lubricating oil in the oil barrel 2 enters the mounting sleeve 36 through the connecting pipe 37, so as to replenish the lubricating oil sprayed by the nozzle 33 in time.

[0039] When the pressure plate 4 moves downward under the action of its own gravity and the elastic force of the pressure spring 41, the guide rod 42 moves downward synchronously, and the guide rod 42 drives the ratchet 5 to rotate through the slider 51 and the spiral groove 44. When the guide rod 42 tends to move upward, the pawl 55 is inserted into the tooth groove of the ratchet 5 under the elastic force of the mounting spring 56, so that the guide rod 42 cannot move upward.
