[0002] Cylindrical drones are a common type of drone in our daily life. A foldable frame is installed on the main body of the cylindrical drone, allowing the cylindrical drone to take off or land on complex ground, avoiding direct contact between the drone and the ground and protecting the drone body. When the drone is not in use, the foldable frame can be disassembled and folded to save storage space.

[0003] Most of the existing foldable racks are installed on the bottom of the cylindrical UAV through buckles. When the UAV is not in use, the rack needs to be disassembled and stored. However, when the foldable rack is installed and disassembled multiple times, the buckles on the foldable rack are prone to wear, making the subsequent installation of the cylindrical UAV unstable and causing shaking, which in turn affects the take-off and landing of the cylindrical UAV. Therefore, to address the above problem, we propose a foldable cylindrical UAV rack. Utility Model Content
