Sliding tube type air compressor

Abstract

The invention belongs to the technical field of compressors, and relates to a sliding tube type air compressor. The sliding tube type air compressor comprises two cylinders, two pistons, a connecting rod, a crankcase, a crank pin, a slide block and a sliding tube, wherein the connecting rod is fixedly connected or integrated with the pistons and the sliding tube; the slide block is provided with a seat hole; the sliding tube is provided with a sliding passage, is arranged in the sliding passage and is in sliding fit with the sliding passage; the crank pin is inserted into the seat hole of the slide block and is directly and rotationally matched with the seat hole; the sliding tube is provided with an oil storage cavity which moves along with the sliding tube; and the oil storage cavity is communicated with the sliding passage of the sliding tube. The crankcase of the compressor can be made into an open structure, so materials can be reduced; in addition, the oil storage cavity moves along with the sliding tube, and can be cooled by using wind produced by relative motion, so lubricating oil has a good cooling effect; and the open crankcase makes external fresh cooler air directly contacted with and cool the oil storage cavity.

Description

Technical field [0001] The invention belongs to the technical field of compressors and relates to a sliding tube type air compressor. Background technique [0002] A typical sliding tube air compressor includes crankcases, pistons, cylinders, connecting rods, crankshafts, crank pins, sliders, and sliding tubes. The crank pins are arranged on the crankshaft or they are simply integrated, with the crank pins surrounding The rotation axis of the crankshaft rotates, the piston of the compressor is placed in the cylinder and reciprocating with the cylinder. One end of the connecting rod is connected with the piston, and the other end of the connecting rod is tightly connected with the sliding pipe or the connecting rod and the sliding pipe adopt an integrated structure , The sliding block is arranged in the sliding pipe and slidingly fitted with the sliding pipe. A seat hole is provided on the sliding block. The crank pin is inserted into the seat hole and directly rotates with the se...

Problems solved by technology

Obviously, this lubrication method requires that the crankcase must be made into a closed structure so as to form an oil pool that can store the lubricating oil, and the defects brought about thereby are: 1) The crankcase is made into a closed structure so that the lubricating oil exchanges heat with the outside world 2) The closed structure of the crankcase increases the number and volume of the crankcase walls, resulting in an increase in the number of compressor manufacturing materials
