Problems solved by technology

[0005] The purpose of the present invention is to overcome the problems existing in the prior art, and to provide a windproof automatic lodging billboard for municipal management. In the case of strong wind, the rotation of the first wind wheel and the second wind wheel can be further blown, so that the rotation of the first wind wheel and the second wind wheel can further drive the The rotation of the third rotating shaft and the fourth rotating shaft can further drive the sliding of the first sliding shaft through the rotating of the third rotating shaft and the fourth rotating shaft, so that the first sliding shaft can be further driven The sliding shaft is separated from the first sliding cavity, and can further pull the rotation of the billboard support frame under the tension force of the first spring, so that the billboard support frame can be further pulled down automatically , thereby achieving the purpose of automatic lodging, avoiding the problem of blowing down the billboard support frame due to excessive wind, further ensuring the safety of pedestrians and property, and being able to It can further drive the rotation of the fifth rotating shaft, so that the rotation of the rotating pressing shaft can be further driven by the rotation of the fifth rotating shaft, so that the synchronous rotation of the connecting thread shaft can be further driven, and it can be passed through the The corresponding meshing connection between the connecting threaded shaft and the threaded connection hole can further use the connecting threaded shaft to fix the billboard support frame, thereby further ensuring the stability of the billboard support frame after falling sex
