Wind-resistant advertising board capable of automatically adjusting height

Abstract

The invention discloses a wind-resistant advertising board capable of automatically adjusting the height, and relates to the technical field of advertising boards. The wind-resistant advertising boardcapable of automatically adjusting the height comprises a board body supporting device, wherein the board body supporting device comprises a bottom plate and an advertising board, a supporting columnis fixedly connected to the center of the upper surface of the bottom plate, a hollow sleeve is slidably connected to the upper end of the circumferential side face of the supporting column, a supporting plate is fixedly connected to the upper surface of the hollow sleeve, a spring is arranged in the hollow sleeve, the bottom of the spring is fixedly connected with the upper surface of the supporting column, and the top of the spring in the hollow sleeve is fixedly connected with the center of the lower surface of the supporting plate, so that the problem that most existing wind-resistant advertising boards do not limit the wind speed while facing strong wind and rotating along with the wind, the advertising board can rotate once the wind blows the advertising board, the advertising watching effect is affected, and meanwhile, unnecessary rotation caused by insufficient wind power can greatly shorten the service life of the device.

Description

technical field [0001] The invention relates to the technical field of billboards, in particular to a wind-resistant billboard whose height can be automatically adjusted. Background technique [0002] As a kind of information dissemination equipment, billboards have been widely used in modern society. Large billboards beside highways, cities, scenic spots, etc. are already very common infrastructure. Billboards are easily affected by strong winds at high places, and may It is damaged or even blown down, so the existing wind-resistant billboards will take some reinforcement measures or enable the billboards to rotate with the wind to reduce the area of ​​the windward surface and prevent them from being damaged by blowing. [0003] For example, a windproof billboard disclosed in the Chinese patent, patent number: CN 108230898 B, the invention discloses a windproof billboard, which includes a board surface assembly, a torsion assembly and a base assembly, and the board surface ...

AI Technical Summary

Problems solved by technology

[0005] However, for example, the above two windproof billboards and most of the existing windproof billboards do not limit the wind speed when facing strong winds and rotate with the wind to reduce the windward side. Once the wind blows, the billboards will rotate, affecting advertising. While watching the effect, unnecessary rotation when the wind is not strong enough will greatly reduce the service life of the device
