Abstract
The invention relates to a single cylinder slide block type air compressor. The structure is characterized in that a motor is arranged in a compressor body; a crankcase is connected with the compressor body; an air cylinder is connected with the crankcase; the air cylinder is connected with a cylinder over through a valve plate; a piston is arranged in the air cylinder; a snifter valve is arranged at the top of the piston; a vent valve is arranged in the valve plate; a vent pipe is arranged on the cylinder head; the air compressor also comprises a crank shaft, a slide block, a chute frame, a piston rod and a needle bearing; the crank shaft is connected with a rotating shaft of the motor; the slide block is connected with the crank shaft through the needle bearing; the slide block is arranged in the chute box so that the upper end and the lower end of the slide block contacts the chute box, while the left end and the right end of the slide block do not contact the chute frame; the piston rod is penetrated in a guide sleeve between the air cylinder and the crankcase; and one end of the piston rod is fixedly connected to the exterior of the chute box, and the other end of the piston rod is fixedly connected with the piston. The invention can avoid the abrasion of a piston ring and the leakage of air, and increase the volumetric efficiency. The invention has the advantages of little vibration, low noise, simple structure, high mechanical efficiency and long service life of the piston.
Description
Technical field
The present invention is a kind of air compressor, particularly a kind of single cylinder slide block type air compressor.
Background technique
Air compressor all has the linear reciprocating motion mechanism of a piston, and this motion is the rotation motion drive crankshaft-and-connecting-rod by prime mover (motor or internal-combustion engine), and connecting rod then drives piston and does linear reciprocating motion.Air inlet in the air compressor, exhaust process are to realize by the linear reciprocating motion of piston.Because when connecting rod drove piston motion, connecting rod had very big lateral force to piston, has increased the frictional force between piston and the cylinder wall, so piston ring weares and teares easily, causes gas easily to leak, and has reduced volumetric efficiency.
Summary of the invention
The objective of the invention is to invent a kind of single cylinder slide block type air compressor that drives translation up and down of chute frame and then drive piston linear reciprocating motion by slide block in order to overcome the existing defective that air compressor gas easily leaks, volumetric efficiency is low.
The objective of the invention is to realize as follows: described single cylinder slide block type air compressor, form by body, motor, crankcase, cylinder, valve plate, cylinder cap and piston; Be provided with motor in the body, crankcase is connected with body, and cylinder is connected with crankcase, and cylinder is connected with cylinder cap by valve plate, is provided with piston in the cylinder, and the top of piston is provided with Aspirating valves, and valve plate is provided with outlet valve, and cylinder cap is provided with outlet pipe; Other has crankshaft, slide block, chute frame, piston rod and needle bearing; Crankshaft is connected with the rotating shaft of motor, slide block is connected with crankshaft by needle bearing, slide block is located in the chute frame, the two ends up and down of slide block are contacted with the chute frame, and the two ends, the left and right sides of slide block do not contact with the chute frame, piston rod is located in the guide sleeve between cylinder and the crankcase, and an end of piston rod is fixed in the outside of chute frame, and the other end of piston rod is fixedlyed connected with piston.
Good effect of the present invention is as follows: because the to-and-fro motion of piston is to drive by the to-and-fro motion up and down of chute frame, so there be not the effect of piston to the lateral force of cylinder, the leakage that this has just been avoided wear of piston-rings and gas has improved volumetric efficiency; Compare with existing air compressor, cylinder height of the present invention, depth pistion all greatly reduce; Because Aspirating valves is located at piston head, the switching of Aspirating valves can be finished automatically by the inertial force that reciprocating motion of the pistons produces, and has avoided the influence of valve pocket gas, simultaneously, gas after the filtration directly enters cylinder by the air intake passage on the piston, has reduced air-breathing preheating; That the present invention vibrates is little, noise is low, simple in structure, mechanical efficiency is high, piston life is long, thereby is specially adapted to the occasion that microminiature does not have oil.

Embodiment
As shown in Figure 1, described single cylinder slide block type air compressor is made up of body 1, motor 2, crankcase 3, cylinder 4, valve plate 5, cylinder cap 6 and piston 7; Be provided with motor 2 in the body 1, crankcase 3 is connected with body 1, and cylinder 4 is connected with crankcase 3, cylinder 4 is connected with cylinder cap 6 by valve plate 5, is provided with piston 7 in the cylinder 4, and the top of piston 7 is provided with Aspirating valves 8, valve plate 5 is provided with outlet valve 9, and cylinder cap 6 is provided with outlet pipe 10; Other has crankshaft 11, slide block 12, chute frame 13, piston rod 14 and needle bearing 15; Crankshaft 11 is connected with the rotating shaft of motor 2, slide block 12 is connected with crankshaft 11 by needle bearing 15, slide block 12 is located in the chute frame 13, the two ends up and down of slide block 12 are contacted with chute frame 13, and the two ends, the left and right sides of slide block 12 do not contact with chute frame 13, piston rod 14 is located in the guide sleeve 16 between cylinder 4 and the crankcase 3, and an end of piston rod 14 is fixed in the outside of chute frame 13, and the other end of piston rod 14 is fixedlyed connected with piston 7.
During work, the driven by motor crankshaft rotation, crankshaft drives slide block translation up and down by needle bearing, when the translation of the slide block left and right sides, because the two ends, the left and right sides of slide block do not contact with the chute frame, so slide block can not drive the left and right sides translation of chute frame, and when slide block up and down during translation, because the two ends up and down of slide block contact with the chute frame, so can only driving the chute frame, slide block moves up and down, the chute frame then drives piston by piston rod and does synchronous pumping.Because the to-and-fro motion of piston, be that the to-and-fro motion by the chute frame drives, so there be not the effect of piston to the lateral force of cylinder, the leakage that this has just been avoided wear of piston-rings and gas has improved volumetric efficiency.
