A flagpole for preventing flags from entanglement

Abstract

The invention discloses a flagpole capable of preventing a flag from being wound. A tail wing plate is parallel to the wind direction, at this time, the wind blowing direction coincides with the flagdirection, and wind blows the flag to fly. Rotating is conducted always until the tail wing plate is parallel to the wind direction. Due to the fact that the tail wing plate is parallel to the wind direction, wind enters a wind inlet channel I of a drainage cap I, thus enters an annular cavity I and finally is blown out through a wind outlet I, airflow blown out from the wind outlet I is perpendicular to the wind direction, therefore, if transverse wind suddenly occurs, the flag is blown reversely by the airflow blown out from the wind outlet I when swinging towards the wind outlet I, and thusthe flag is prevented from being wound. The wind enters an annular cavity II through a wind inlet channel II in a drainage cap II and finally is blown out from a wind outlet II, airflow blown out from the wind outlet II is perpendicular to the wind direction, therefore, if the transverse wind suddenly occurs, the flag is blown reversely by the airflow blown out from the wind outlet II when swinging towards the wind outlet II, and thus the flag is prevented from being wound.

Description

technical field [0001] The invention relates to the technical field of elevating flag flagpoles, in particular to a flagpole that prevents flags from being entangled. Background technique [0002] Major primary and secondary schools hold flag-raising activities every week. After the national flag is raised on Monday, it is generally necessary to lower the flag on Friday during non-holidays. After the national flag is raised to the top of the flagpole, it flutters with the wind. Since the position of the flag is fixed relative to the flagpole, when there is a strong wind or the wind direction is not fixed, the flag is easy to wrap around the flagpole. If the winding is too tight, the flag will be lowered. The flag cannot be pulled down from the flagpole smoothly. [0003] Chinese patent (CN107044220B) discloses a lifting device and a winding flagpole. The flag 102 is fixed on the flagpole 103, and the flagpole 103 is installed on the slide 130 through the bearing 104. Under...

Problems solved by technology

However, when the wind direction is unstable or the wind is strong, the flagpole 103 cannot rotate in a short time, so the flag 102 will still be wound on the sliding tube 130
