Adjustable compressor air cylinder supporting structure

An adjustable compressor air cylinder supporting structure at least comprises an upper connecting plate, a lower connecting plate assembly and a bottom plate. The lower connecting plate assembly is connected between the upper connecting plate and the bottom plate. The lower connecting plate assembly comprises a lower connecting plate. The adjustable compressor air cylinder supporting structure further comprises a fastening bolt assembly. The lower connecting plate is provided with a connecting hole for the fastening bolt assembly to penetrate through. The upper connecting plate is provided with a vertical kidney-shaped circular hole for the fastening bolt assembly to penetrate through and vertically slide by a certain distance so as to adjust the supporting height, and the lower connecting plate is provided with a guiding block. Accordingly, the whole supporting height can be conveniently adjusted, a compressor air cylinder can be kept in one horizontal plane, the abrasion of a supporting ring to the air cylinder is effectively reduced, the abrasion of a piston to the air cylinder due to intensive abrasion of the supporting ring is avoided, and the running reliability of compressor equipment is improved.
