Embodiment Construction

[0013] figure 1 Among them, a wind-shielding anti-falling device is added between the billboard (1) and the bracket (5). The device is mainly composed of a turntable (4) and a rotating shaft (2). An annular spring groove is opened on the turntable, and a A compression spring partition (7) and a pair of limit protrusions (8), two compression springs (6) are embedded in the groove, the tail ends of which withstand the compression spring partition (7), and the positive ends are respectively set on the compression spring caps (9) then withstands the limit protrusion (8) to provide reset force for the rotating shaft (2); the lower end of the rotating shaft (2) is inserted into the hole of the turntable, and a Г-shaped toggle spring arm ( 3), its bottom end is just inserted in the gap between two compression spring caps, and any compression spring (6) can be pressed.

[0014] During installation, the billboard (1) is fixed on the upper end of the rotating shaft, and there must be ...

Abstract

The invention discloses a device for a large outdoor billboard to avoid strong wind and prevent falling. The device mainly comprises a rotating shaft, a turntable, a pressure spring and the like; during mounting, the billboard is fixed at the upper end of the rotating shaft; and the vertical centre of the billboard deviates a certain distance from the axis of the rotating shaft. When the billboard is subjected to noser, certain torsion is formed on the rotating shaft; when the torsion reaches a certain degree, the billboard can rotate a certain angle automatically to avoid the strong wind and prevent the billboard from falling; and when the strong wind becomes weaker, the billboard resets automatically.

Description

Technical field [0001] The invention relates to a device capable of avoiding strong winds and preventing falling of large outdoor billboards. technical background [0002] As the area and height of large outdoor billboards become larger and higher, they are more and more likely to be blown down by strong winds, resulting in economic losses and personal injuries; on the other hand, due to the wind resistance of billboard brackets The requirements are getting higher and higher, so that the cost of construction has soared. Contents of the invention [0003] In order to improve the wind shelter and anti-fall performance of the existing billboards, the present invention provides a device that can hide the billboards from strong winds and prevent them from falling over. The purpose of dumping. [0004] The technical solution adopted by the present invention to solve its technical problems is: The anti-wind and anti-fall device is mainly composed of a turntable and a rotating ...
