Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to an assembled, movable LED display. Background Technology

[0002] An LED display screen is a panel display device composed of light-emitting diode modules. It can display various information such as text, images, and videos. It usually integrates electronic technology, computer technology, and information processing technology. It has the characteristics of bright colors, wide dynamic range, and high brightness. Common assembled LED displays are usually made by splicing together multiple detachable LED displays.

[0003] According to Chinese Patent Publication No. CN222277999U, entitled "An Assembled Movable LED Display Screen," the main components include a chassis 1 and a chassis 2. Base plates are fixedly connected to the outer bottom ends of both chassis 1 and chassis 2. Universal wheels are fixedly connected to the front and rear sides of the bottom ends of both base plates. Support plates are fixedly connected to the outer top ends of both chassis 1 and chassis 2. A shaped groove is formed in the middle of the left end of chassis 1. A telescopic plate is fixedly connected to the middle of the right end of chassis 2, and the telescopic plate is slidably connected to the shaped groove. A straight rod is rotatably connected to the lower middle part of chassis 1, and a threaded rod is fixedly connected to the left end of the straight rod. The threaded rod is threadedly connected to the lower middle part of chassis 2. A [missing information - likely a design element] is formed in the middle of the left side of the top end of chassis 1. The telescopic plate has several slots at its top center, and a locking mechanism is fixedly connected to each slot. A rotating column is rotatably connected to the upper center of each of the two support plates. An mounting plate is fixedly connected to each adjacent end of the rotating column. A ratchet is fixedly connected to the outer end of the rotating column on the right side. A protective cover is fixedly connected to the upper right side of the right support plate. A sleeve is fixedly connected to one side of the protective cover. A slot is formed inside the sleeve, and a rocker arm is slidably connected within the slot.
