ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an air compressor, and more particularly to an air compressor having an improved structure for allowing the air compressor to be easily and quickly assembled.
2. Description of the Prior Art
Typical air compressors comprise a single support member, and a large amount of elements and members required to be assembled onto the support member. Normally, the air compressors comprise a compact size such that the elements may not be easily and quickly assembled onto the single support member.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional air compressors.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an air compressor including an improved structure for allowing the elements of the air compressor to be easily and quickly assembled together.
In accordance with one aspect of the invention, there is provided an air compressor comprising a cylinder housing including an outlet port, a pressure gage attached to the cylinder housing, a compression device including a piston container slidably received in the cylinder housing and including a post extended upward therefrom and including a disc provided on top of the post, the disc including a pin extended upward therefrom, a compression valve and a positioning block engaged onto the post and retained on the post with the disc, the post and the disc including at least one air inlet formed therein and communicating with an interior of the piston container, a valve piece engaged on the pin of the disc, a limiting piece including a fastening portion engaged with the pin for securing the valve piece on the pin of the disc, and a link including an upper portion pivotally secured to the piston container and including a bottom portion, a seat including an orifice formed therein, a motor secured to the seat and including a pinion engaged through the orifice of the seat, a transmission device including a gear rotatably securing to the seat at a pivot shaft and engaged with the pinion and driven by the motor via the pinion, the gear including a non-circular casing provided thereon, the gear including a first half having a thick toothed portion provided thereon for engaging with the pinion of the motor and including a second half having a thin toothed portion provided thereon for engaging with the pinion of the motor, a weight including a non-circular shape engaged in the non-circular casing and rotated in concert with the gear, the weight being engaged on the shaft and rotated in concert with the shaft, the weight including an axle extended therefrom and rotatably engaged through the lower portion of the link for moving the link up and down when the weight is rotated by the shaft, and means for securing the seat to the cylinder housing.
The seat includes at least one sleeve provided therein, and the cylinder housing includes at least one project ion extended therefrom and engaged into the sleeve of the seat.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
