Description

Technical Field

[0001] This utility model relates to the field of roller blind billboard technology, specifically a roller blind billboard. Background Technology

[0002] Roller blind billboards are a form of advertising that uses a rolling mechanism to display or hide advertising images. They utilize LED screens or other forms of advertising visuals, presented through rolling, rotating, or other methods, resulting in unique visual effects and strong appeal.

[0003] Patent CN209765971U discloses a roller shutter advertising board, which includes a storage shaft and a roller shutter advertising board body. The roller shutter advertising board body is located inside the storage shaft and in contact with the storage shaft. A transverse groove is chiseled at the upper end of the storage shaft. Two symmetrical upper openings and a fixing groove are chiseled at the bottom end of the transverse groove. A clamping block is fixedly connected between two sliding rods of the device. The clamping block is located in the lower groove. Two mounting columns are fixedly connected at the bottom end of the clamping block. This device can make it easier to remove the storage shaft from the roller shutter and improve the operator's replacement efficiency.

[0004] However, the existing device involves directly installing the retractable shaft in the desired position and then rotating the main body of the roller blind billboard from the retractable shaft to display and advertise the content. However, the bottom of the main body of the roller blind billboard does not have a counterweight mechanism, meaning that the bottom of the main body of the roller blind billboard is relatively light. As a result, it is easy for it to sway under impact or wind during daily use, thus affecting the normal display and advertising of the advertisement. To address this issue, a roller blind billboard is proposed to solve the problem that the existing roller blind billboard is easily affected by the environment, which reduces the display and advertising effect.
