The present invention relates to a fixing device of a motor of an air compressor which is configured to fix the motor on a body of the air compressor and the air compressor is received in an accommodation box without using any screws.
A conventional air compressor contains a body, a cylinder connected on the body, a motor fixed on the body, and a piston driven by the motor to move in the cylinder reciprocately, such that the motor actuates the piston to move in the cylinder reciprocately, thus sucking, compressing, and discharging airs. Furthermore, the air compressor is received in an accommodation box.
The motor is fixed on the body by screws, but it is easy to remove from the body after a period of using time. When the screws are inserted through the body to screw with multiple threaded orifices of a casing of the motor, a tool is difficult to screw the screws with the multiple threaded orifices in a limited space. Therefore, the motor cannot be fixed on the body by using the screws easily.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide a fixing device of a motor of an air compressor which contains the multiple cavities of the motor configured to engage on the multiple posts of the body, and the at least one retainer is configured to fix the body and the motor, wherein the first end of the at least one retainer is engaged with the body, and the second end of the at least one retainer is engaged on the casing of the motor so that the motor is fixed on the body securely without using any screws.
Another aspect of the present invention is to provide a fixing device of a motor of an air compressor by which the air compressor is received in the accommodation box, and a retaining portion of an inner wall of the accommodation box has a trench configured to limit the at least one retainer between the motor and the body so as to avoid the removal of the at least one retainer from the air compressor.
With reference to
The body 1 includes multiple positioning orifices which are a first positioning orifice 11 and a second positioning orifice 12, wherein a small gear 61 is received in the first positioning orifice 11 and is connected on an end of the motor 4, and a connection seat 41 of the motor 4 is accommodated in the first positioning orifice 11. The second positioning orifice 12 is configured to receive a bearing 121. The motor 4 includes a magnetic coil 45 fitted thereon, made of metal material, and configured to conduct magnetism, thus enhancing operation efficiency of the motor 4.
The cylinder 2 is one-piece connected on the body 1 and is in communication with an air storage holder 3, wherein the air storage holder 3 includes at least one tube 30 in which an air hose 31 and a pressure gauge 32 are received.
A transmission mechanism 6 includes a large gear 62 having a counterweight block and configured to mesh with the small gear 61, wherein the large gear 62 is connected with a piston rod 51 of the piston 5 by using an eccentric crank, and the transmission mechanism 6 actuates the piston 5 to move in the cylinder 2 reciprocately so as to produce compressed airs.

With reference to
As illustrated in
Referring to
Thereby, the fixing device of the motor 4 of the air compressor 10 contains the multiple cavities 43 of the motor 4 configured to engage on the multiple posts 110 of the body 1, and the at least one retainer 7 is configured to fix the body 1 and the motor 4. For example, the first end of the at least one retainer 7 is engaged with the body 1, and the second end of the at least one retainer 7 is engaged on the casing of the motor 4 so that the motor 4 is fixed on the body 1 securely without using any screws.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
