DETAILED DESCRIPTION

[0018] The utility model is further explained in detail in connection with the accompanying drawings.

[0019] This embodiment discloses a kind of wall-mounted direct current screen fixing mechanism, such as Figs. 1 to 4As shown, including the DC screen body 1, back fixing device 2, the back fixing device 2 includes both sides of the fixed mainboard 21 and a plurality of fixed connecting plates 22, the fixed connecting plate 22 is arranged so that the utility model installation is completed, the DC screen body 1 and the installation wall surface have a certain reserved gap, so that air can flow, which helps the heat dissipation of the utility model; The length of the fixed connecting plate 22 is greater than the DC screen body 1. When installing the DC screen body 1, the fixed connecting plate 22 longer than the DC screen body 1 has more space for placement, and the DC screen body 1 can be simply and conveniently installed and placed on the fixed connecting plate 22; The fixed mainboard 21 is provided with mounting protrusions A211 with openings on both sides, the fixed connecting plate 22 is connected to both sides of the fixed mainboard 21, the DC screen body 1 is provided with mounting protrusions B11 on both sides, the mounting protrusions B11 arranged on the DC screen body 1 are easy to observe during installation, and can always appear in the field of view during installation without being blocked by the DC screen body 1, so that the DC screen body 1 is simple and reliable during installation, the mounting protrusions B11 are provided with a set of fixed mounting hooks 12 and a plurality of sets of movable mounting hooks 13 adapted to the fixed connecting plate 22, and the fixed mounting hooks 12 are close to the upper end surface of the DC screen body 1. The fixed mounting hooks 12 and the movable mounting hooks 13 are used for the installation of the DC screen body 1, and the fixed mounting hooks 12 and the movable mounting hooks 13 cooperate with the fixed connecting plate 22 to enable the DC screen body 1 to be stably installed on the fixed connecting plate 22.

[0020] Further improvement, the fixed connecting plate 22 is provided with a pressing mechanism 23. The pressing mechanism 23 is arranged at one end of the fixed connecting plate 22, and exerts pressure on the side surface of the DC screen body 1, so that the DC screen body 1 does not move on the fixed connecting plate 22 after installation.

[0021] Further improvement, the pressing mechanism 23 includes a pressing block 231 provided with a spring, and the pressing block 231 is provided with a limiting folding mechanism 232. The pressing block 231 will press the installed DC screen body 1, so that the installed DC screen body 1 is close to and contacts the other side, and the normal pressure between the pressing block 231 and the installed DC screen body 1 can provide good friction to enable the installed DC screen body 1 to be stably arranged on the fixed connecting plate 22.

The arrangement of the two pressing blocks 231 close to the upper and lower end surfaces enables the use of fewer pressing blocks 231 while enabling the whole side of the installed DC screen body 1 to be stressed, which can avoid uneven stress on the installed DC screen body 1, cause the installed DC screen body 1 to be lifted by one side, cause instability, and improve the stability of the utility model.

[0023] Further improvement, the fixed web plate 22 is provided with a movable sleeve 221. The movable sleeve can slide on the fixed web plate 22. When the DC screen body 1 is installed, the DC screen body 1 moves along with the movement of the movable sleeve. The position of the DC screen body 1 relative to the fixed web plate 22 is simply adjusted, the labor cost for adjusting the utility model is reduced, and the service life of the fixed web plate 22 is prolonged.

[0024] Further improvement, the DC screen body 1 is provided with a handle structure 3 for controlling the movable mounting hook 13. The handle structure 3 is convenient for gripping the DC screen body 1, and when the handle structure 3 is gripped and pressed, the handle structure 3 can control the movable mounting hook 13 to rotate. The movable mounting hook 13 can be simply detached from the fixed web plate 22, so that the DC screen body 1 is conveniently and detachably installed.

[0025] Further improvement, the handle structure 3 comprises a movable pressing plate 31, the movable pressing plate 31 is provided with a pulling line 32, and the pulling line 32 is connected with the movable mounting hook 13. When the movable pressing plate 31 is pressed downward, the pulling line 32 is pulled. The pulling line 32 is connected with the movable mounting hook 13, the movable mounting hook 13 is provided with a rotatable circular rotating shaft, the pulling line 32 pulls the rotating shaft to rotate, and the rotating rotating shaft rotates the movable mounting hook 13.

[0026] Working principle of the utility model

[0027] When the utility model is installed, the back fixing device 2 is arranged at a position to be installed through the installation protrusion B11. The movable sleeve 221 arranged on the fixed main plate 21 is moved to the side close to the pressing block 231. The DC screen body 1 is pulled up by using the handle structure 3. When the DC screen body 1 is pulled up by using the handle, the movable pressing plate 31 of the handle structure 3 is pressed downward, so that the movable mounting hook 13 is pulled and rotated by the pulling line 32. The hook body of the rotated movable mounting hook 13 is parallel to the fixed web plate 22 and does not hinder the installation of the DC screen body 1. Only the fixed mounting hook 12 needs to be simply installed on the fixed web plate 22, the position of the DC screen body 1 is adjusted, the handle structure 3 is released, the rotated movable mounting hook 13 is simply inserted into the fixed web plate 22, the limiting folding mechanism 232 is released to release the pressing block 231, the pressing block 231 is released, the DC screen body 1 is stably and reliably fixed, wiring and debugging of the DC screen body 1 are completed, and the DC screen body 1 can be used.

[0028] When the utility model is disassembled, the pressing block 231 is folded by using the limiting folding mechanism 232, the handle structure 3 is gripped, the movable mounting hook 13 is rotated by pressing the movable pressing plate 31, the movable mounting hook 13 is detached from the fixed web plate 22, and the DC screen body 1 can be simply and conveniently disassembled.

[0029] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
