An inspection door 8 is installed on one side of the bottom bracket 1, and the inspection door 8 is connected to the bottom bracket 1 by a hinge.

[0032] Working principle: During use, when transporting this device, the operator only needs to simultaneously rotate the telescopic rod 3 out of the storage slot 11, extending the telescopic rod 3 so that its upper end is inserted into the lower end of the top bracket 4. Then, the operator inserts the limiting pin 6 into the top bracket 4 and the telescopic rod 3. At this time, the protective cloth 12 is automatically laid on the outside of the LED display screen 2 under the action of the telescopic rod 3. Simultaneously, as the telescopic rod 3 rotates and extends, its top gradually rises, causing the cleaning connecting plate 14 to move upwards. This allows the cleaning felt 15 at the rear end of the cleaning connecting plate 14 to wipe the outside of the LED display screen 2, making the LED display... The exterior of the LED display screen 2 is kept clean. The device features a storage slot 11 for easy storage of the telescopic rod 3 and protective cloth 12, resulting in a neater appearance. Installing the telescopic rod 3, via the limiting pin 6, onto the lower end of the top bracket 4, allows the protective cloth 12 to be extended, thus covering the exterior of the LED display screen 2. This reduces the risk of damage to the LED display screen 2 during transport, improving the device's impact resistance. Furthermore, it eliminates the need for time-consuming wooden frame packaging during transport; simply pulling out the telescopic rod 3 and protective cloth 12 allows for quick and easy packing, enhancing the device's overall performance. To improve packaging efficiency and reduce transportation time costs, the installation of a cleaning connecting plate 14, which is slidably connected to the connecting shaft 16, ensures that the cleaning connecting plate 14 remains horizontal during the rotation of the telescopic rod 3. This also allows the cleaning connecting plate 14 to retract into the storage slot 11 along with the telescopic rod 3 when it is retracted, making the device more convenient to use. The installation of a cleaning felt plate 15 allows the cleaning connecting plate 14 to move upwards along with the top of the telescopic rod 3 when it is extended, enabling the cleaning felt plate 15 at the rear end of the cleaning connecting plate 14 to clean the exterior of the LED display screen 2, keeping the exterior of the LED display screen 2 clean. Installing the pull-back spring 13 allows the top bracket 4 to move downwards, enabling the top of the telescopic rod 3 to be inserted into the interior of the top bracket 4. This facilitates the use of the limit pin 6 to install the telescopic rod 3 at the lower end of the top bracket 4, making the device more convenient to use. Installing the foam layer 18 improves the device's impact resistance, preventing damage to the LED display screen 2 when external impacts hit the upper part of the device. Installing the waterproof layer 17 improves the device's waterproof capability, preventing water from wetting the device and providing waterproof protection for the LED display screen 2. Installing the velvet layer 19 prevents the protective cloth 12 from scratching the exterior of the LED display screen 2, enhancing the device's protective capability.
