DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1~Figure 3As shown, this embodiment proposes an LED display screen with convenient switching, including a display screen body 1, a fixing member 2 is fixedly connected to one side of the rear portion of the display screen body 1, a power supply assembly 3 is fixedly connected to the rear end of the fixing member 2, a mounting plate body 4 is fixedly connected to the rear side of the display screen body 1, a threaded rod 5 is connected to the inside of the mounting plate body 4 through a bearing, a rotating column 6 is fixedly connected to the bottom of the threaded rod 5, a rotating plate 7 is fixedly connected to the bottom of the rotating column 6, threaded blocks 9 are threadedly connected to the outside of the threaded rod 5 on both sides, movable rods 11 are fixedly connected to one side of the two threaded blocks 9, and fixed clamping plates 12 are fixedly connected to one end of the two movable rods 11.

[0027] In this embodiment, the rotating column 6 passes through the bottom of the mounting plate 4 and is connected to the mounting plate 4 via a bearing. The threads on both sides of the outer side of the threaded rod 5 have opposite rotation directions, which can facilitate the rotation and support work of the rotating column 6.

[0028] In this embodiment, vertical plates 8 are fixedly connected to both sides of the outside of the mounting plate body 4, and limiting rods 10 are fixedly connected to one side of the outside of the two threaded blocks 9, which can facilitate the fixed connection of the vertical plates 8 on the outside of the mounting plate body 4.

[0029] In this embodiment, limiting grooves are provided inside the two vertical plates 8 , and the two limiting rods 10 extend into and contact the two limiting grooves respectively, which can facilitate the movement and limiting of the limiting rods 10 .

[0030] In this embodiment, a plurality of anti-skid pads 13 are fixedly connected inside the two fixed clamping plates 12 . The plurality of anti-skid pads 13 are arranged and distributed in a linear shape. The friction between the device and the wall mounting parts can be ensured by the anti-skid pads 13 .

[0031] In this embodiment, the cross section of the limiting rod body 10 is set to be L-shaped, and a circular plate is fixedly connected to the rear side of the mounting plate body 4.

[0032] When it is necessary to install the display screen body 1, the staff first needs to move the display screen body 1 to a suitable position and then rotate the rotating plate 7 clockwise. The rotating plate 7 will synchronously drive the rotating column 6 to rotate during the rotation, and the rotating column 6 will synchronously drive the threaded rod 5 to rotate during the rotation. The threaded rod 5 will synchronously drive the threaded blocks 9 on both sides to move toward the middle during the rotation, and the threaded block 9 will synchronously drive the limiting rod body 10 to move during the movement, thereby ensuring that the threaded block 9 can move longitudinally. At the same time, since the threaded block 9 will synchronously drive the movable rod 11 to move during the movement, the movable rod 11 will synchronously drive the fixed card plate 12 to move during the movement, and the fixed card plate 12 will synchronously drive the anti-skid pad 13 to move during the movement. If the fixed card plates 12 on both sides drive the anti-skid pads 13 on both sides to contact the mounting piece in the middle of the wall, the staff will rotate the rotating plate 7 to a state where it cannot rotate, and the installation of the display screen body 1 on the surfaces of mounting pieces at different positions or with different sizes can be completed, thereby ensuring the flexibility of the device when used.

[0033] Example 2

[0034] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a matching plate 14 is fixedly connected to the bottom of one of the threaded blocks 9, and the inside of the matching plate 14 is in contact with the outer surface of the threaded rod 5, which can facilitate the movement of the matching plate 14.

[0035] In this embodiment, a cleaning brush 15 is fixedly connected to one side of the matching plate 14. There is a gap between the cleaning brush 15 and the anti-slip pad 13 and they do not contact each other, so that the cleaning brush 15 can clean the dust accumulated on the surface of the wall mounting part.

[0036] In the process of fixing the display screen body 1, since the threaded block 9 will synchronously drive the movable rod 11 to move during the movement, the movable rod 11 will synchronously drive the fixed card plate 12 to move during the movement, and the threaded block 9 will also synchronously drive the matching plate 14 to move during the movement, and the matching plate 14 will synchronously drive the cleaning brush 15 to move during the movement, and the cleaning brush 15 will synchronously clean the dust and impurities on the top of the installation part during the movement, and then the impurities will be swept off, thereby ensuring the anti-skid effect of the subsequent anti-skid pad 13, avoiding the situation of weakening friction, and facilitating the overall installation of the device;

[0037] When the staff needs to turn on the display screen body 1, the end of the power supply assembly 3 is inserted into the wall socket to power on.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
