[0035] In the related art, the power socket is fixed somewhere on the wall, and the length of the power cord is limited, that is, the power socket limits the position of the display.

[0036] refer to Figure 1-Figure 4 In view of the above problems, this embodiment provides a wall-mounting device for hanging a display 100, including:

[0037] The first connection structure 1 is used for fixed connection with the wall. The first connection structure 1 includes a slide groove 11. A first conductive connection portion connected to the power bus is provided on a first sliding connection surface of the slide groove 11. The first conductive connection portion extends along the extension direction of the first sliding connection surface (reference Figure 1 X direction) extension setting;

[0038] The second connection structure includes a sliding portion and a sliding connection shaft 22, wherein the sliding portion is slidably connected in the sliding groove 11, a first end of the sliding connection shaft 22 is connected to the sliding portion, and a second end of the sliding connection shaft 22 is connected to the display 100;

[0039] The second end is provided with a power socket, and a power connection line extending from the power socket to the first end is provided in the sliding connection shaft 22. The sliding part includes a second sliding connection surface slidably connected to the first sliding connection surface, and the second sliding connection surface is provided with a second conductive connection part connected to the power connection line.

[0040] Using the above technical solution, the first connecting structure 1 for fixed connection with the wall includes a slide groove 11, and the second connecting structure for connecting with the display 100 includes a sliding part and a sliding connecting shaft 22. The sliding part is slidably connected in the slide groove 11, the first end of the sliding connecting shaft 22 is connected to the sliding part, and the second end of the sliding connecting shaft 22 is connected to the display 100, thereby realizing the sliding connection of the display 100 in the slide groove 11.

[0041] If a conventional power plug-in method is adopted, even if the display 100 can move along the slide slot 11, its moving space is limited because the length of the power cord is limited and it is not advisable to set a power cord that is too long. In order to effectively solve the problem of limited position due to the power socket, the first sliding connection surface of the slide slot 11 of the present application is provided with a first conductive connection portion connected to the power bus, the second end of the sliding connection shaft 22 is provided with a power socket, and a power connection line extending from the power socket to the first end is provided in the sliding connection shaft 22, and the sliding portion includes a second sliding connection surface slidably connected to the first sliding connection surface, and the second sliding connection surface is provided with a second conductive connection portion connected to the power connection line. Since the sliding part is slidably connected to the slide slot 11, the second sliding connection surface of the sliding part is always in contact with the first sliding connection surface of the slide slot 11, whether in a stationary state or a moving state, and a first conductive connection part connected to the power bus is provided on the first sliding connection surface, and a second conductive connection part connected to the power connection line is provided on the second sliding connection surface, that is, as long as the sliding part is slidably connected in the slide slot 11, the first conductive connection part and the second conductive connection part are in a conductive state, and the second end of the sliding connection shaft 22 is provided with a power socket, which can be adapted to the power socket on the display 100 to supply power to the display 100.
