After the supporting rod assembly 12 is detached from the display box 40, the supporting rod assembly 12 can position the second end of the supporting rod assembly 12 on the supporting foot assembly 11 by passing the clamping pin 31 provided on the second end through the limiting opening and rotating the clamping shaft section 312 of the clamping pin 31 in the limiting groove by a preset angle. When the locking shaft section 312 is rotated into place, the support rod assembly 12 can be swung along the axis of the locking shaft section 312 in the direction close to the display box 40, so that the first end of the support rod assembly 12 moves into the accommodating recess. When the support rod assembly 12 is swung into place, the first connecting hole 23 on the first end of the support rod assembly 12 can be coaxial with the first mounting through hole on the pin fixing seat 21. At this time, the quick release pin 22 can connect the first end of the support rod assembly 12 to the pin fixing seat 21 by passing through the first mounting through hole, the accommodating recess, the first connecting hole 23, the accommodating recess and the second mounting through hole in sequence. At this time, the support assembly provided in this embodiment forms a triangular support structure with the display box 40 and the support foot assembly 11 on the side of the display box 40 away from the display surface, thereby effectively improving the overall rigidity of the display device provided in this embodiment and its safety in a collision environment.

[0071] In summary, the implementation of the support device and display equipment provided in this embodiment has at least the following beneficial technical effects: the support device provided in this embodiment is provided with a support foot assembly 11 at the bottom of the display box 40, so that the display box 40 can be supported by the support foot assembly 11. At the same time, since the two ends of the support rod assembly 12 provided in this embodiment can be respectively connected to the display box 40 and the support foot assembly 11, the support rod assembly 12 provided in this embodiment can form a triangular support structure with the display box 40 and the support foot assembly 11 on the side of the display box 40 away from the display surface. Compared with the outdoor stadium screen in the prior art, the display device provided with the support device provided in this embodiment can effectively improve its overall stiffness and safety performance in a collision environment.

[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
