Telescopic flagpole
The invention discloses a telescopic flagpole which comprises a sleeve type telescopic rod, a driving device and an elastic thin steel belt. A box of the driving device is internally provided with a guide rail with an arc concave face and a chain transmission system, the elastic thin steel belt extends into the sleeve type telescopic rod from the part between the chain transmission system and the guide rail and is fixed to the uppermost section sleeve pipe of the sleeve type telescopic rod, columnar protrusions on an outer chain plate of a chain of the chain transmission system are meshed with through holes formed in the elastic thin steel belt to drive the elastic thin steel belt to move vertically, and thus the sleeve type telescopic rod is controlled to stretch and contract. According to the telescopic flagpole, a pulley system for lifting and lowering a flag can be omitted, and both the flag lifting speed and the flag lowering speed can also be controlled.
