Outdoor rotating columnar advertising board

Abstract

The invention discloses an outdoor rotary columnar advertising board. The advertising board comprises a base, a supporting stand column, a rotary outer barrel, barrel-shaped billboard transmitting andclamping devices and an advertising board body. The supporting stand column can be driven by a stand column motor to rotate, and the top of the supporting stand column is fixedly connected with the advertising board body; a solar integrated board is arranged at the top of the advertising board body; the periphery of the supporting stand column is sleeved coaxially with the rotating outer barrel,and an opening is formed in one side of the rotary outer barrel; the barrel-shaped billboard transmitting and clamping devices are arranged between the top of the rotary outer barrel and the supporting stand column as well as between the bottom of the rotary outer barrel and the supporting stand column respectively; each barrel-shaped billboard transmitting and clamping device comprises an outer electromagnet layer, outer steel balls, an inner elastic layer and inner steel balls, wherein the outer steel balls are evenly embedded into the outer electromagnet layer, the inner steel balls are evenly embedded into the inner elastic layer, and the radial distance between the inner steel balls and the outer steel balls is larger than the thickness of the barrel-shaped billboard. The barrel-shaped billboard can be rapidly loaded into the outdoor rotary columnar advertising board, and is convenient to detach. Meanwhile, the billboard is clamped stably without shaking.

Description

technical field [0001] The invention relates to the technical field of cultural media equipment, in particular to an outdoor rotating columnar advertising board. Background technique [0002] Billboards generally refer to all outdoor media that convey advertising information. The size of the media depends on the actual environment, such as shop signs, door signs, etc. The pictures on the facade can be drawn by hand, made by computer or printed on paper.

Neon sign advertisements are installed in bustling downtown areas, which not only promote products, but also embellish the city. Advertiser's request, with the consent of the relevant advertising management department to draw, so it is very eye-catching and beautiful. However, most of the advertisements can only be viewed from one side, and cannot play a three-dimensional and all-round publicity role...

AI Technical Summary

Problems solved by technology

[0005] In the patent application with application number 201320671157.8, although the side wall of the cylinder in the outdoor rotating columnar advertising board is provided with an opening for the billboard to enter, however, because the billboard is made of flexible material, and the annular groove of the roller is uneven, The gap is so small that it is very difficult to place the billboard ring in the clamp without flattening it

In addition, it takes a long time to install and replace the advertisement once, and the labor efficiency is low and the labor cost is high.

[0006] In the patent application with the application number 201320671502.8, although the billboard fixing device can fix and clamp the outdoor rotating columnar advertising board, however, the setting of the circular fixing ring, the stretching deformation range of the circular fixing ring is small, and the stretching is non-existent. The shape is round, so that the size of the outdoor rotating columnar advertising board is very small, that is, it can only adapt to some outdoor rotating cylindrical advertising boards with a small diameter range, and the versatility is not strong

In addition, one loading and unloading requires four cylinders to work at the same time. On the one hand, it increases the investment cost of the equipment, and at the same time, it is not energy-saving and environmentally friendly.
