Description

Technical Field

[0001] This utility model relates to the field of anti-tipping devices for billboards, specifically an anti-tipping device for high-altitude billboards. Background Technology

[0002] Nowadays, billboards are widely used to display product information of enterprises or merchants and play a promotional role. As enterprises or merchants update their products, the content displayed on the billboards also needs to be updated. Billboards are generally installed at high places and fixed to the mounting frame with fastening bolts. When it is necessary to replace the billboard, the traditional installation method requires all the fastening bolts to be removed, which is extremely inconvenient and greatly reduces the work efficiency of the staff. Moreover, billboards are prone to tipping over when subjected to external impact.

[0003] Chinese patent CN210516135U discloses an advertising billboard with an anti-tipping structure that is easy to install. The billboard includes a main body, a top cover, and two fixed bases. The top of the main body is fixedly connected to the bottom of the top cover. Mounting grooves are provided on both sides of the bottom of the main body, and the bottoms of the two mounting grooves engage with the tops of the fixed bases. Advertising panels are fixedly installed on both sides of the main body. Each fixed base includes a shaped bracket, legs, and two anti-tipping rods. The bottom of the shaped bracket is fixedly connected to the legs, and the top ends of the legs are fixedly connected to the anti-tipping rods. This invention provides an advertising billboard with an anti-tipping structure that is easy to install. The billboard installation and fixing operation is simple and convenient. The two anti-tipping rods prevent the billboard from tipping over. When the billboard is tilted, based on the principle of a self-righting toy, the anti-tipping rods use their own curvature to adjust the center, restoring the billboard to its upright position.

[0004] The anti-tipping device of the aforementioned patent has two arc-shaped anti-tipping bars on the base of the billboard, which use the roly-poly design to prevent the billboard from tipping over when it is standing on the ground, but it is not applicable to billboards installed on high-altitude exterior walls.

[0013] This utility model consists of a fixing block located below the middle of two top rods, a connecting rod on the fixing block, a connecting block at the lower end of the connecting rod, a rope at the lower end of the connecting block, and a counterweight ball at the end of the rope furthest from the connecting block. First connecting plates are located at both ends of the top rods, and a second connecting plate is located below the first connecting plate. A connecting top plate is located below the second connecting plate, and a limiting frame is located at the lower end of the connecting top plate. A connecting bottom plate is located at the end of the limiting frame furthest from the connecting top plate. When the billboard is installed on the connecting bottom plate, the four sides of the billboard are inserted into the limiting frame, and then the limiting frame is connected to the connecting bottom plate. When the anti-tipping device is installed on a high-altitude exterior wall with the billboard, if the wind is too strong, the counterweight ball sways. The damper principle is used to counteract the swaying caused by the wind, achieving the purpose of preventing overturning. This effectively avoids the problem that existing anti-tipping devices, which use two arc-shaped anti-tipping rods on the base of the billboard to prevent it from tipping over when standing on the ground, are not suitable for billboards installed on high-altitude exterior walls.
