A free-spinning flagpole

Abstract

The invention discloses a free rotating flag post, and belongs to the technical field of small machinery. The technical problem needing to be solved is to provide the free rotating flag post, two ropes of the traditional flag post do not need to be pulled, a flag freely rotates with the wind and is not wound on the flag post because of the blowing wind; the technical scheme adopted for solving the technical problem is as follows: the free rotating flag post comprises a flag post standpipe, a lifting mechanism, a rotation hauling mechanism and a flag suspension and a hauling rope, the flag post standpipe comprises a flag post upper pipe, a flag post middle part and a flag post lower pipe, the rotation hauling mechanism rotates around the top end of the flag post upper pipe, the flag suspension is located at the outer periphery of the flat post standpipe, one end of the hauling rope is fixed on the lifting mechanism, the other end of the hauling rope penetrates through the interior of the flag post standpipe, enters the rotation hauling mechanism, gets out from the rotation hauling mechanism, and is connected on the flag suspension, the hauling rope is controlled through the lifting mechanism, then the flag suspension is lifted up and down along the outer part of the pipe wall of the flag post standpipe, and the flag suspension freely rotates on the excircle of the flag post standpipe through the rotation hauling mechanism.

Description

technical field [0001] The invention relates to a freely rotating flagpole, which belongs to the technical field of small machinery. Background technique [0002] When raising the flag on the traditional flagpole, two ropes are needed. If the flagpole is high, the two ropes are not easy to control the flag surface, and when the wind blows, the rope makes a lot of noise when it hits the flagpole. The wind will roll on the flagpole, not only does the flag flutter unsightly, but it is also easy to wind the flag and damage it. [0003] In the prior art, the invention of the rotating flagpole is realized by installing a slewing bearing under the base of the flagpole. As everyone knows, the bearing under the base of the flagpole needs to bear a large moment, and two large slewing bearings are required. The price of the bearing is high and it is inconvenient to install. , It is not suitable to use the base to install the bearing to solve the rotation problem. Contents of the inv...
