Electric inflation lifting flag pole
The invention discloses an electric inflation lifting flag pole which comprises a hollow foundation section, a plurality of sleeved flag pole sections and an air bag. The flag pole sections are hollow rods, wherein openings are formed in the two ends of the flag pole sections, are sleeved with the foundation section and form the coaxially-matched structure with the foundation section. The air bag is arranged at the axis of the foundation section. The longitudinal section of each flag pole section is in a trapezoid shape so that each flag pole section can slide and limit the flag pole section sleeved with the flag pole section. An annular limiting protrusion is arranged at the upper end inside the foundation section. The air bag is in a cylindrical shape after being inflated. The electric inflation lifting flag pole is novel in structure, high in practicability and suitable for various scenes where a flag needs to be lifted, and has the high generalization performance.
