Description

Air compressor device

This creation is an air compressor device, especially a practical technology that can assemble a motor without using screws and can be stably fixed on the main frame, and the entire air compressor viscera assembly can be accommodated in a box.

A conventional air compressor includes a main frame, a cylinder combined with the main frame, a motor assembled on the main frame, and a piston body that can be driven by the motor to reciprocate in the cylinder. It drives the piston body to reciprocate in the cylinder to complete gas inhalation, compression and discharge of pressurized gas. The entire air compressor visceral assembly can be arranged in a box.

Generally speaking, the motors of conventional air compressors are mostly fixed on the main frame by screws. When the air compressor is in operation for a long time, the screws are easy to fall off or loosen, which reduces the service life. The screws must pass through the main frame. The frame body is locked on the screw holes of the motor housing, and if the tool for locking the screws cannot pass through the main frame body and its surrounding components due to space constraints, the motor cannot be smoothly locked to the main frame with screws. superior. In view of the deficiencies in the design of conventional air compressor devices, the author of this author developed it, and developed this creation after many efforts.

The main purpose of this creation is to provide an air compressor device, the device includes an air compressor viscera assembly and a box for holding the air compressor viscera assembly, wherein the motor of the air compressor viscera assembly is a At least one positioning portion is extended at the head end to be snapped and assembled with the main frame, so that the motor can be assembled without using screws and can be stably fixed on the main frame.

When the air compressor is placed in the box body, the convex column inside the box body is embedded into the heat dissipation port on the cylindrical peripheral surface of the motor, so that the air compressor can be compressed. During the operation of the machine or when it is collided and turned over by an external force, the motor will not be released from the fixed state of the hook between the motor and the main frame due to the impact and flip of the external force.

A transmission mechanism 6 includes a large gear 62 with a weight. The large gear 62 can be meshed with the aforementioned pinion 61. The large gear 62 is connected with the aforementioned bearing 121 by a shaft (in the prior art diagrams). Not shown), the transmission mechanism 6 can drive the piston body 5 to perform a reciprocating compression action in the aforementioned cylinder 2 to generate compressed air.

As shown in the first to sixth figures, the present invention is characterized in that: the motor 4 casing system is provided with a plurality of positioning portions 45 extending from the head end 42 of the motor 4 , and a hook portion 451 is fastened at the end of the positioning portion 45 , and The main frame 1 is provided with through holes 13 penetrating up and down relative to the plurality of positioning portions 45 , and a ring-shaped positioning groove 14 is recessed in the outer periphery adjacent to the first positioning holes 11 of the main frame 1 . The portion 45 extends through the through hole 13 on the main frame 1, and the motor 4 rotates again, so that the hook portion 451 at the end of the positioning portion 45 abuts on the ring-shaped positioning groove 14, so that the motor 4 does not need to be used. The screws can be assembled and fixed on the main frame 1 stably.

Please refer to Figures 5 and 6 for the schematic diagram of placing the visceral assembly of the air compressor 10 in a box 7 , the inner walls of the upper and lower casings of the box 7 correspond to the cylindrical shape of the motor 4 casing. The position of the heat dissipation port 43 on the peripheral surface is provided with a plurality of convex columns 71. When the air compressor 10 is placed in the box body 7, the convex columns 71 on the inner side of the box body 7 are embedded in the heat dissipation on the cylindrical peripheral surface of the motor 4. In the opening 43, when the air compressor 10 is in operation or is collided and turned over by an external force, the motor 4 will not be released from the fixed state of the hook between the motor 4 and the main frame 1 due to the impact of the external force.

In view of the foregoing, the present invention provides a snap-fit assembly through the positioning portion 45 extending from the head end 42 of the motor 4 and the main frame 1 of the air compressor 10, so that the motor 4 can be assembled without using screws and can be stably fixed. Set on the main frame 1 , the visceral assembly of the air compressor 10 is installed inside the box body 7 . 71, so that the motor 4 will not be turned over due to the impact of external force, and the fixed state of the hook between the motor 4 and the main frame 1 will not be released.
