The dismounting efficiency is high, and the dismounting mode is simple, without the need of other tools for dismounting. Therefore, the maintenance efficiency can be improved, and the time and effort consumed for maintenance can be reduced. After the display module 2 is fixed to the bearing seat 1, the sealing frame 7 can reduce the gap between the bearing seat 1 and the display module 2, and reduce the occurrence of the damage of the display module 2 caused by foreign matters entering the bearing seat 1. The sealing frame 7 is positioned by the jacking piece, without the need of manual adjustment, so as to improve the installation speed of the display module 2.

[0033] Further, the jacking member comprises a rotating shaft 17 fixedly connected to the side wall of the base frame 3, a top rod 19 rotatably connected to the rotating shaft 17, a side rod 20 fixedly connected to the top rod 19 and arranged perpendicularly to the top rod 19, a pressing block 22 arranged above the side rod 20, an extension rod 21 fixedly connected to the bottom of the pressing block 22 and the top of the base frame 3, and a torsion spring 23 fixedly connected between the rotating shaft 17 and the top rod 19, and the top end of the top rod 19 is in contact with the bottom of the sealing frame 7.

[0034] Specifically, when the connecting member moves downward, the connecting member presses the pressing block 22 to move downward, the pressing block 22 pushes the side rod 20 to rotate along the rotating shaft 17, at this time, the top rod 19 rotates, the top of the top rod 19 pushes the sealing frame 7 to move upward, thereby reducing the gap between the display module 2 and the bearing seat 1, avoiding the problem that the stability of the display module 2 after being installed by the connecting member and the fixing mechanism is reduced due to the gap between the display module 2 and the bearing seat 1, and improving the safety of the display module 2 during use. The rotation of the top rod 19 is driven by the pressure of the pressing block 22 when the connecting member moves downward. This way, manual adjustment of the position of the display module 2 is not required, and the convenience of the present application during use can be improved.

[0035] Further, the connecting member comprises an L-shaped plate 24, one side of the L-shaped plate 24 is fixedly connected with an auxiliary rod 25, the auxiliary rod 25 is provided with a clamping groove 26 matched with the clamping rod 6, and the L-shaped plate 24 is fixedly connected with a pressing plate 27 matched with the pressing block 22.

[0036] Specifically, the pressing plate 27 provided on the L-shaped plate 24 can press the pressing block 22 to move during the installation of the display module 2, and the auxiliary rod 25 can be used to fix the position of the display module 2 by matching the clamping rod 6 and the clamping groove 26 during the installation of the display module 2, thereby reducing the operation steps of the display module 2 installation and improving the installation efficiency.

The top of the bearing seat 1 is provided with a placing groove for placing the sealing frame 7, thereby reducing the occupied space when the sealing groove is not in use.

[0043] Further, to improve the stability of the top rod 19 and the clamping rod 6 in use, the end portions of the top rod 19 and the clamping rod 6 are provided with arc surfaces.
