[0002] An outdoor advertising machine is a commercial display device designed specifically for outdoor environments, used to display various advertising contents, capable of displaying information under various weather conditions, providing high-quality visual and auditory enjoyment for outdoor information dissemination, and widely applied in various fields such as the CBD of commercial areas, bus stops with large passenger flows, airports, railway stations, docks, park squares, leisure places, tourist attractions, high-end communities, the catering industry, government and enterprise publicity, etc.

[0003] The advertising machine needs to be placed outdoors. Most of the existing advertising machines only connect the display screen to the frame through a locking mechanism, which is easily damaged by external factors and has poor safety performance. For example, the Chinese utility model patent application document with the publication number CN213898473U discloses a locking structure of an outdoor advertising machine. Through the mutual cooperation of a pulley, a guide groove seat, and a tensioning slope, the locking rod of the locking assembly can drive the rear door panel to closely abut against the frame before locking is completed, effectively achieving the tight closure and easy locking between the rear door panel and the frame. However, components such as its handle 72 and the locking parts provided on the handle 72 are exposed outside for a long time, and the lock hole and the metal part around it may accelerate rusting and aging due to environmental factors (such as rain, dust, etc.), resulting in inconvenient unlocking or even damage, and at the same time, the anti-theft performance is poor.
