During this process, this embodiment may be only provided with one plug-in mechanism of the LED display device, and the function switching component 17 at the first working position can drive the driving part to move at a time, so as to form contact switching-on between the first power supply plug-in part 12 and the second power supply plug-in part 202 and contact switching-on between the first signal plug-in part 14 and the second signal plug-in part 23. In the technical solution of this embodiment, the power supply plugging assembly and the signal plugging assembly which are separately arranged and are separately assembled in the related art are integrated, and the contact switching-on of the first plug-in assembly 10 and the second plug-in assembly 20 can be achieved during the mounting process of two display units, thus shortening the working time, reducing the workload, and increasing the working efficiency. Therefore, the technical solution of this embodiment effectively solves the problem that the working efficiency is relatively low due to the fact that the assembling time of the power supply plugging assembly and the assembling time of the signal plugging assembly are relatively long in the related art.

In this embodiment, in order to push the function switching component 17 by the pushing part 24 to enable the first power supply plug-in part 12 and the first signal plug-in part 14 to synchronously move and be synchronously plugged with the second power supply plug-in part 202 and the second signal plug-in part 23 respectively to facilitate force application, the first power supply plug-in part 12 and the first signal plug-in part 14 are located on two sides of the function switching component 17, the pushing part 24 is preferably a pushing pin, and the second power supply plug-in part 202 and the second signal plug-in part 23 are located on two sides of the pushing pin.

As shown in FIG. 1 to FIG. 7, during the mounting or debugging process of the plurality of display units, it is necessary to ensure that the power supplies and signals of some display units are both switched on, or only the power supplies or signals are switched on, or both the power supplies and signals are not switched on, so as to adapt to mounting or debugging requirements, and the above-mentioned first working position is a position where the signals and power supplies are switched on. When the function switching component 17 is located at the first working position, the first power supply plug-in part 12 is switched from the first switching-off position to the first switching-on position, and the first signal plug-in part 14 is switched from the second switching-off position to the second switching-on position. In this way, the function switching component 17 first selects a function to meet the mounting or debugging requirements of the display units in which the power supplies and signals are switched on.

As shown in FIG. 1 to FIG. 7, the function switching component 17 also has a second working position and a third working position. When the function switching component 17 is located at the second working position, the function switching component 17 can drive the first driving component 15 to move and avoid the second driving component 16; and when the function switching component 17 is located at the third working position, the function switching component 17 can drive the second driving component 16 to move and avoid the first driving component 15. When the function switching component 17 is located at the second working position, the pushing part 24 pushes the first driving component 15 to move through the function switching component 17, so as to enable the first power supply plug-in part 12 to be switched from the first switching-off position to the first switching-on position and enable the first signal plug-in part 14 to be maintained at the second switching-off position. In this way, the function switching component 17 first selects a function to meet the mounting or debugging requirements of the display units in which only the power supplies are switched on. When the function switching component 17 is located at the third working position, the pushing part 24 pushes the second driving component 16 to move through the function switching component 17, so as to enable the first signal plug-in part 14 to be switched from the second switching-off position to the second switching-on position and enable the first power supply plug-in part 12 to be maintained at the first switching-off position. In this way, the function switching component 17 first selects a function to meet the mounting or debugging requirements of the display units in which only the signals are switched on. The above-mentioned second working position is a position where the power supply is switched on, and the above-mentioned third working position is a position where the signal is switched on.

As shown in FIG. 1 to FIG. 7, the function switching component 17 also has a fourth working position. When the function switching component 17 is located at the fourth working position, the function switching component 17 avoids the driving part. When the function switching component 17 is located at the fourth working position, the pushing part 24 pushes the function switching component 17 to move, so as to enable the first power supply plug-in part 12 to be maintained at the first switching-off position and enable the first signal plug-in part 14 to be maintained at the second switching-off position. In this way, the function switching component 17 first selects a function to meet the mounting or debugging requirements of the display units in which both the power supplies and signals are not switched on. The above-mentioned fourth working position is a position where the signal and power supply are switched off.

As shown in FIG. 1 to FIG. 7, in order to facilitate the automatic switching of the first power supply plug-in part 12 from the first switching-on position to the first switching-off position, and the automatic switching of the first signal plug-in part 14 from the second switching-on position to the second switching-off position, the first plug-in assembly 10 further includes a first reset component 21 and a second reset component 22 which are arranged in the first seat body 11. The first reset component 21 applies a first reset force for switching the first power supply plug-in part 12 from the first switching-on position to the first switching-off position to the first driving component 15, and the second reset component 22 applies a second reset force for switching the first signal plug-in part 14 from the second switching-on position to the second switching-off position to the second driving component 16. In this way, the separation of the first plug-in assembly 10 and the second plug-in assembly 20 can be achieved during the disassembly process of two display units, thus further shortening the working time, reducing the workload, and greatly increasing the working efficiency. The first reset component 21 and the second reset component 22 are both preferably compression springs.

As shown in FIG. 1 to FIG. 7, the function switching component 17 includes a function switching piece 171 and a first lug 172 and a second lug 173 which are arranged on the function switching piece 171 at an interval. When the function switching component 17 is located at the first working position, the first lug 172 can drive the first driving component 15 to move, and the second lug 173 can drive the second driving component 16 to move.

When the function switching component 17 is located at the first working position, the first lug 172 can drive the first driving component 15 to move, and the second lug 173 can drive the second driving component 16 to move. At this time, the function switching piece 171 can simultaneously push the first lug 172 and the second lug 173 thereon to move together, so as to simultaneously drive the driving part to move.

As shown in FIG. 1 to FIG. 7, when the function switching component 17 is located at the second working position, the first lug 172 can drive the first driving component 15 to move, and the second gap 175 avoids the second driving component 16. In this way, during the moving process of the function switching component 17, the second driving component 16 is avoided, the first signal plug-in part 14 is maintained at the second switching-off position, and the function switching piece 171 can only push the first lug 172 thereon to move together, so as to drive the first driving component 15 to move. When the function switching component 17 is located at the third working position, the second lug 173 can drive the second driving component 16 to move, and the first gap 174 avoids the first driving component 15.
