Abstract
The utility model relates to an air compressor. A grating-shaped connecting rod fixing disc the middle of which is provided with a through hole is arranged at the lower part of a cylinder; one end of a connecting rod penetrates through the through hole and is fixedly connected with a piston; a spring is sheathed on the connecting rod of the lower part of the connecting rod fixing disc; the spring is fixed on the connecting rod after compressed; the other end of the connecting rod is pressed on the periphery of an impeller provided with an impeller blade by the spring. The utility model has the advantages of easy production and low cost, and can be used for various air compressor manufactories.
Description
The utility model relates to a kind of air compressor.
At present, the air compressor that people often use generally all is to promote piston motion in the cylinder with connecting rod.The connecting rod of this mechanism and crank and piston are hinged, generally all will use bearing in the hinged place, and the crank making is also complicated, and the fabricating cost of air compressing mechanism is also higher like this.
The purpose of this utility model provides a kind of simple in structure, lower-cost air compressor.
The purpose of this utility model is achieved through the following technical solutions: this model utility air compressor comprises the piston in cylinder and the cylinder, is connected connecting rod on the piston, and piston motion mechanism; Being shaped on a centre in the cylinder bottom has the grid shape connecting rod fixed tray of through hole, and an end of described connecting rod passes this through hole and is fixed on the piston, is with spring on the connecting rod of connecting rod fixed tray bottom, is fixed on the connecting rod after this spring is compressed; Described piston motion mechanism one is installed in the impeller in the rotating shaft, being shaped as of this impeller: more than 2 is the arc limit one side be evenly equipped with on the basic circle circumference of a same radius, another side is the wheel blade of the straight line that overlaps with the Base radius elongation line, and the arc limit of each wheel blade is adjacent with the straight line of another wheel blade; The other end of described connecting rod is pressed on the described impeller by spring.
The utility model has following advantage with comparing of connecting rod air compressor commonly used now: its connecting rod and piston are fixed together, rather than hinged, and without bearing, fabricating cost is lower; Its piston motion mechanism is an impeller, and the structure of impeller is simple with respect to crank, and fabricating cost is also low.
Below in conjunction with drawings and Examples, the utility model air compressor is described further.
Fig. 1 is the air compressing mechanism schematic representation of this real novel air compressor.
As shown in Figure 1, this air compressor comprises the piston 2 in cylinder 1 and the cylinder 1, is connected the connecting rod 3 on the piston 2, and impeller 4; Be shaped on a centre in cylinder 1 bottom the grid shape connecting rod fixed tray 5 of through hole is arranged, one end of connecting rod 3 passes this through hole and is fixed on the piston 2 with pin, be with spring 6 on the connecting rod 3 of connecting rod fixed tray 5 bottoms, this spring 6 is fixed on the connecting rod 3 by spring backing pin 7 after compression; Impeller 4 is shaped as and is evenly equipped with 4 one side on basic circle 9 circumference of a same radius is the arc limit, and another side is the wheel blade 8 of the straight line of basic circle 9 radius elongation lines coincidence, and the arc limit of each wheel blade 8 is adjacent with the straight line of another wheel blade; For the weight that alleviates leaf light 4 is shaped on hole 10 on impeller 4; The other end of described connecting rod 3 is pressed on the periphery of impeller 4 by spring 6.
During air compressor work, as can be seen from Figure 1 impeller 4 is installed in the rotating shaft, clockwise rotates, and piston 2 is promoted by the arc limit of the wheel blade 8 of impeller 4, is not having the impeller part on arc limit, and piston 2 is promoted by spring 6; Formed the back and forth movement of piston 2 like this.
Claims (2)
