The outer tube 320 is a hollow tubular structure, alternatively, the outer tube 320 is a hollow square tube or a round tube, and the outer tube 320 is fixedly connected with the wall hanging bracket 10, for example, the outer tube 320 and the wall hanging bracket 10 can be fixedly connected by a fastener such as a screw or a bolt, and in addition, the outer tube 320 and the wall hanging bracket 10 can be fixedly connected by welding, clamping, or the like.

The lead screw 321 and the lead screw nut 322 are both positioned on the inner side of the outer tube 320, wherein the lead screw nut 322 is relatively fixed with the outer tube 320, the lead screw 321 is arranged along the vertical direction and positioned below the driving motor 31, the driving motor 31 is in transmission connection with the lead screw 321, and the lead screw 321 is arranged in the lead screw nut 322 in a penetrating way and in threaded connection with the lead screw nut 322.

When the height of the display device needs to be adjusted, the driving motor 31 is started, the driving motor 31 drives the screw rod 321 to rotate, and relative motion is generated between the screw rod 321 and the screw rod nut 322, and because the screw rod nut 322 is relatively fixed with the outer tube 320, the screw rod 321 can vertically move up and down relative to the screw rod nut 322, so that the screw rod 321 drives the driving motor 31 and the mounting bracket 20 on the driving motor 31 to vertically move, and then the display device on the mounting bracket 20 can vertically move along with the mounting bracket 20, and the height adjustment of the display device is realized.

It can be understood that the driving motor 31 is a forward/reverse rotation motor, so that the driving motor 31 can drive the display device to rise when rotating in one direction (e.g. forward rotation), and can drive the display device to fall when rotating in the other direction (e.g. reverse rotation).

Optionally, a gap is formed between the engaging portion 2201 and the adapter plate 21, so that the engaging portion 2201 is engaged with the hook portion 2210.

Alternatively, the hook portion 2210 is a hook groove formed on the mounting bar 221, the engaging portion 2201 is a hook adapted to the hook groove, and in addition, the hook portion 2210 may be a hook formed on the mounting bar 221, and the engaging portion 2201 is a hook adapted to the hook.

In some embodiments, the mounting frame 220 further includes a tightening portion 2202 disposed on the lower side of the main body portion 2200, and optionally, the main body portion 2200, the engagement portion 2201, and the tightening portion 2202 are integrally formed to ensure structural strength of the mounting frame 220. The mounting strip 221 is further provided with a abutting piece 222 arranged at intervals with the clamping hook portion 2210, the abutting piece 222 is movably mounted on the mounting strip 221 and can move to be in abutting fit with the abutting portion 2202 along the length direction of the mounting strip 221, specifically, the abutting piece 222 can move to be in abutting fit with one side surface of the abutting portion 2202, which is away from the main body portion 2200, along the length direction of the mounting strip 221, so that the abutting piece 222 abuts against the abutting portion 2202 when the mounting strip 221 is clamped and hung on the mounting frame 220, assembly stability of the mounting strip 221 on the mounting frame 220 is guaranteed, and looseness of the mounting strip 221 is avoided. Moreover, when the display device is mounted on the mounting bar 221 and then the mounting bar 221 is clamped on the mounting frame 220, the conventional screw locking mode and other modes are not easy to operate because the gap between the display device and the mounting surface is smaller, but the embodiment of the application only needs to simply adjust the abutting piece 222 to move along the length direction of the mounting bar 221 to abut against the surface of one side, away from the main body portion 2200, of the abutting portion 2202, so that the assembly stability of the mounting bar 221 on the mounting frame 220 can be ensured, and the operation is convenient.

Alternatively, the abutting member 222 may be a fastener such as a bolt or a screw, for example, the abutting member 222 is a bolt, the abutting member 222 is in threaded connection with the mounting bar 221, and when the mounting bar 221 is clamped on the mounting frame 220, the abutting member 222 is screwed to abut against the abutting portion 2202, so as to avoid loosening of the mounting bar 221.

Based on the same inventive concept, the embodiment of the present utility model also provides a display apparatus including the wall hanging structure 100 as in any of the above embodiments and a display device fixedly mounted on the mounting bracket 20.

In this embodiment, the display device may be an intelligent device such as a display, a touch-control integrated machine, or a flat-panel television, and the display device is fixedly mounted on the mounting surface through the wall-hanging structure 100, and optionally, the mounting surface may be a wall surface or a display board surface.

Taking a mounting surface as an example of a wall surface, the following describes the entire mounting process of the display device on the wall surface by the wall-hanging structure 100:

the driving motor 31 and the mounting frame 220 are fixedly mounted on both sides of the adapter plate 21, respectively, and the outer tube 320 is fixedly mounted on the wall-hanging bracket 10;

the wall hanging bracket 10 is fixedly arranged on the wall surface, so that the wall hanging bracket 10, the driving motor 31, the outer tube 320, the adapter plate 21 and the mounting frame 220 are integrally fixed on the wall surface;

The mounting bar 221 is fixed on the back surface of the display device, and the mounting bar 221 is caught on the mounting frame 220, so that the display device and the mounting bar 221 are mounted on the mounting frame 220 as a whole, thus completing the wall-mounted mounting of the display device.

It should be noted that, the above installation process may be flexibly adjusted according to an actual installation scene, and cannot be understood as the only installation process of the display device on the wall surface.

Since the display device includes the wall-mounted structure 100 in any of the above embodiments, the display device also has the advantages in any of the above embodiments, and specific advantages are described in detail above and are not repeated here.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the utility model, the steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; while the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
