Multifunctional flagpole
The invention relates to the technical field of flagpoles, in particular to a multifunctional flagpole. Comprising a hollow vertical rod, a rotary joint, an air guide device and an air outlet barrel, the vertical rod, the rotary joint and the air guide device are sequentially communicated, the top plate seals the upper end of the air guide device, and a rotary plate is arranged on the vertical rod; the vertical rod blows air to the inside through the air inlet; an air outlet is formed in the air guide device and is hermetically communicated with an upper-end cylinder opening of the air outlet cylinder, and a lower-end cylinder hole of the air outlet cylinder is hermetically and fixedly connected with the rotating plate; an air outlet notch is formed in the air outlet cylinder; a vertical pipe is further arranged at the air outlet notch and used for installing a flag. When external wind is small, the air supply device can be started, and the blown air flows to the air guide device through the rotary joint along the hollow vertical rod, then flows into the air outlet barrel from the air outlet and finally is blown to the flag from the air outlet notch, so that the flag is effectively stretched; when external wind is strong, the flag is unbalanced in stress, force deviating towards one side can drive the rotating plate and the upper portion of the rotating connector to rotate, and the flag rotates along with the rotating plate and the upper portion of the rotating connector, so that the flag cannot be wound on the flagpole.
本发明涉及旗杆技术领域，具体为一种多功能旗杆；包括空心的立杆、旋转接头、导风装置和出风筒；立杆、旋转接头和导风装置依次接通，顶板封住导风装置上端，立杆上设有转板；立杆通过进风口向内部鼓风；导风装置上开有出风口，与出风筒的上端筒口密封连通，出风筒的下端筒孔与转板密封固定连接；出风筒上开设有出风槽口；在出风槽口处还设有竖管，用于安装旗子。外界风小时，可以启动送风装置，吹出的风沿着空心的立杆，经旋转接头到导风装置，再从出风口到出风筒内，最后从出风槽口吹出到旗子上，使得旗子有效的舒展开来；外界风大时，旗子受力不均衡，往一侧偏的力会带动转板和旋转接头的上部分旋转，旗子也跟着转动，从而不会缠绕到旗杆上。
