Problems solved by technology
[0003] After the current three-sided billboard is used for a period of time, due to mechanical wear and deformation, it is easy to cause the pictures of the three-sided billboard to be unable to be on the same plane when the triangular prism is rotated, which affects the display effect of the three-sided billboard
In addition, the three-sided billboard is easily deformed or toppled due to excessive force in windy weather, which seriously affects the use of the three-sided billboard

Embodiment Construction
[0043] The present invention will be described below with reference to the accompanying drawings; however, it should be understood that these descriptions are illustrative only and are not intended to limit the scope of the present disclosure. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present disclosure. All terms (including technical and scientific terms) used herein have the meaning commonly understood by one of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted to have a meaning consistent with the context of this specification, and not be interpreted in an idealized or overly rigid manner.
[0044] A three-sided billboard device, characterized in that: such as figure 1 , 2 As shown, it includes a base 1, a vertical fixing plate 2, a housing 3, a servo motor 7, a drive shaft 8, a first rotatin...

The invention belongs to the technical field of advertising boards, and particularly relates to three-side-overturning advertising board equipment. The three-side-overturning advertising board equipment comprises a servo motor, a base, a three-side-overturning mechanism, a grooved pulley mechanism and a first rotating shaft. When the three-side-overturning mechanism switches advertisements throughoverturning actions for a long time, some structures in the three-side-overturning mechanism can have mechanical abrasion or mechanical accumulative transmission errors; and due to the design that arectangular inserting barrel is matched with three second L-shaped plates in an inserted mode, a second rotating shaft can be guaranteed to rotate continuously and accurately by 120 degrees, thereby guaranteeing that the three-side-overturning mechanism can maintain the overturning precision during long-time overturning operation. When the three-side-overturning advertising board is affected by strong wind, the three-side-overturning advertising board equipment can keep the sharp corners of a triangular prism in a frontal windward state continuously through automatic adjustment, so that the wind force borne by the triangular prism is weakened to a certain extent, the wind resistance of the triangular prism is enhanced to a certain extent, and then the wind resistance of the three-side-overturning advertising board is improved to a certain extent.
Description
technical field [0001] The invention belongs to the technical field of billboards, and in particular relates to a three-side flip billboard device. Background technique [0002] The billboard is a kind of outdoor advertising media, which consists of a group of triangular prisms positioned side by side. The three-sided flip billboard is controlled by a PLC controller, driven by a motor, and driven by a cam, so that all the triangular prisms rotate around their central axis, and flip in different forms and sequences according to the pre-set methods, and freeze to form three dynamic pictures. [0003] After the current three-sided billboard is used for a period of time, due to mechanical wear and deformation, the pictures of the three-sided billboard cannot be on the same plane when the triangular prism is rotated, which affects the display effect of the three-sided billboard. In addition, the three-sided billboard is easily deformed or toppled due to excessive force in windy ...
