Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the figure: oil-free superhigh pressure compressor connecting rod compression mechanism, including motor 2, eccentric wheel 33, connecting rod 9, concentric cylinder gland 4, its characterized in that: the upper end of the connecting rod 9 is connected with a concentric piston 32 through a first pin shaft 10, the top of the concentric piston 32 is connected with a plurality of connecting rods 12 through threads, and the connecting rods 12 penetrate through a concentric cylinder gland 4 and are connected with a low-pressure piston through screws 28; the upper part of the concentric cylinder gland 4 is connected with a high-pressure cylinder sleeve 29 through threads, the low-pressure piston is connected with a high-pressure push rod 25 through threads, and the outer ring of the high-pressure push rod 25 is arranged in the high-pressure cylinder sleeve 29; the low-pressure piston comprises a low-pressure piston lower cover 18 and a low-pressure piston upper cover 22, the low-pressure piston upper cover 22 is clamped on the low-pressure piston lower cover 18, a low-pressure piston ring 24 is arranged at the contact position of the outer ring of the low-pressure piston lower cover 18 and the low-pressure piston upper cover 22, a valve plate 20 is arranged in an air chamber of the low-pressure piston upper cover 22, and a baffle 21 is arranged between the valve plate 20 and the low-pressure piston upper cover 22; a groove is formed in the outer ring of the low-pressure piston upper cover 22, a third O-shaped ring 23 is arranged between the low-pressure piston ring 24 and the groove, a groove is formed in the outer ring of the low-pressure piston lower cover 18, and a second O-shaped ring 19 is arranged between the groove and the low-pressure piston upper cover 22; a sealing ring is sleeved at the contact position of the screw 28 and the low-pressure piston upper cover 22; and a sealing ring is sleeved at the contact position of the connecting rod 12 and the low-pressure piston lower cover 18.
