Description

Technical Field

[0001] The present invention relates to the technical field of barriers, and in particular to an automatic flip-type advertising barrier and an installation method thereof. Background Art

[0002] Barriers are commonly installed at intersections or parking lot entrances and exits to facilitate the orderly entry and exit of vehicles. Barriers primarily include straight-arm barriers, curved-arm barriers, and fence barriers. Fence barriers are widely used due to their relatively stable structure. They consist of an upper beam and a lower beam, hingedly connected by a connecting rod, forming a quadrilateral structure. A motor is installed at one end of the upper beam, which rotates the upper beam, which in turn rotates the lower beam via the connecting rod, thereby raising the barrier. To increase the strength of the barrier and increase its economic benefits, blades are installed between the upper and lower beams for printed advertising. When the barrier is raised, the blades rotate to reduce the impact of wind on the barrier, leaving gaps between the blades for air flow. This requires a transmission mechanism installed between the upper and lower beams to drive the blades' rotation.

[0003] Existing barriers often have motors installed inside the upper or lower beams to drive the blades to rotate. This method of using motors to drive the blades increases the cost of the barrier and is inconvenient to install due to the relatively small space between the upper and lower beams.
