Embodiment
Below in conjunction with accompanying drawing, specify specific embodiments of the invention.
Fig. 1 is one embodiment of the present invention in oblique view.
As shown in Figure 1: the present invention includes motor 1, casing 2, crank 3, cylinder 4, cylinder cap valve plate group 5, piston rod group 6, gas holder 7, outlet pipe 8, one-way valve 9, eccentric fan 10, pressure control switch 11, safety valve 12, wherein motor 1, casing 2, cylinder 4 and pressure control switch 11 place on the gas holder 7, cylinder 4 is positioned at casing 2 tops, and motor 1 is positioned at the rear portion of casing 2.Cylinder 4 tops are cylinder cap valve plate group 5, and inside is provided with piston rod group 6.Be provided with crank 3 in the casing 2, it is driven by motor 1, and also is provided with eccentric fan 10 at crank 3 axle heads, and eccentric fan 10 rotates synchronously with crank 3, to strengthen the radiating effect in the casing.
After motor 1 starts, drive crank 3 and eccentric fan 10 and rotate synchronously, piston rod group 6 is moved reciprocatingly in cylinder 4, descending air-breathing by the control of cylinder cap valve plate group 5, up exhaust realizes compressed-air actuated function.
In addition, the relief opening of cylinder 4 is communicated with gas holder 7 by outlet pipe 8, and an one-way valve 9 is set between outlet pipe 8 tail ends and gas holder 7, makes pressurized air flow to gas holder 7 from cylinder 4, and can not be back to cylinder 4 from gas holder 7.
In addition, according to the pressure condition of gas in the gas holder 7, whether pressure control switch 11 controls air compressor work automatically.And safety valve 12 plays the safety protection effect in air compressor.When pressure in the gas holder 7 surpassed specified value, safety valve was opened, and a part of gas in the gas holder 7 is entered atmosphere, makes the pressure in the gas holder 7 be no more than permitted value, thereby guaranteed that gas holder 7 does not have an accident because of overpressure.
Fig. 2 is the plan view of piston rod group; Fig. 3 is the left view of Fig. 2; Fig. 4 is the sectional drawing of the A-A direction of Fig. 3.
Extremely shown in Figure 4 as Fig. 2: piston rod group 6 comprises connecting rod 13, piston ring 14, piston ring trim ring 15.Stuffing box bearing with band lubricating grease between connecting rod 13 bottom major parts and the crank 3 links to each other, connecting rod 13 tops are provided with piston ring seat 13a, connecting rod 13 is integrally formed with piston ring seat 13a, wherein, piston ring 14 and piston ring trim ring 15 are enclosed within on the piston ring seat 13a of connecting rod 13, piston ring trim ring 15 is positioned at the top of piston ring 14, and piston ring 14 is fixed on the connecting rod 13.End face circumference at connecting rod 13 close piston ring trim rings 15 evenly is provided with aperture 16, so that the circumferential outer expansion distortion of connecting rod end face, extrusion piston ring trim ring 15, can not come off so that piston ring trim ring 15 is fixed on the connecting rod 13, this kind fixation method is structurally more simple than the method that adopts screw threads for fastening to connect between trim ring and connecting rod.
In addition, the material of piston ring 14 is a teflon, has self lubricity, can reduce the friction with cylinder, prolongs its working life.And piston rod group 6 is being done with crank 3 in the process that pumps, and also can produce the inclination of piston rod group, but because piston ring 14 has stronger extension performance, and the angle that tilts is very little, thus the tightness of cylinder 4 is well guaranteed.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
