Description

Motor combined positioning structure of air compressor

This creation is a motor combined positioning structure of an air compressor, especially a practical technology that can assemble the motor without using screws and can be stably fixed on the substrate.

Please refer to the seventh and eighth figures, which shows a conventional vehicle-mounted air compressor 1 including a base 11, a cylinder 12 coupled to the base, and a motor assembled on the base. 13 and a piston body 14 which can be driven by the motor 13 to reciprocate in the cylinder 12. The piston body 14 is driven by the motor 13 to reciprocate in the cylinder 12 to complete the intake, compression, and discharge of the pressurized gas.

Generally speaking, the motor 13 of the conventional vehicle-mounted air compressor 1 is mostly fixed to the base 11 by screws 15. When the air compressor 1 is operated for a long period of time, the screws 15 are liable to fall off or become loose and cause use. Reduced life.

Please refer to the ninth and tenth drawings again. When the cylinder length of the cylinder 12 of the conventional vehicle-mounted air compressor 1 is longer, the motor 13 cannot be smoothly combined with the base 11 due to space constraints, that is, the motor 13 cannot be used.
