[0036] See also Figure 6A folded edge 31 is provided on one side of the display panel 3, and a window glass 8 is provided on the other side. The folded edge 31 of the display panel 3 allows moisture to be discharged from the outside, reducing the problem of water vapor entering the interior of the LED display body 2, and ensuring the airtight and waterproof performance of the display. A first mounting frame 32 for mounting a circuit board and a second mounting frame 33 for mounting a liquid display are provided in the inner cavity of the display panel 3. A window pane hole corresponding to the liquid crystal display 9 is opened on the display panel 3 to facilitate the display of the content of the liquid crystal display 9. The circuit board is used to control the liquid crystal display 9, and the circuit board is electrically connected to an external control device.
[0037] See also Figure 7 A side of the display box 4 is provided with a positioning boss 41 adapted to the folded edge 31 of the display panel 3, so that the display panel 3 and the display box 4 are movably nested and connected, and a plurality of wire binding seats 42 are fixedly connected to the display box 4 to facilitate wiring arrangement. A side of the display box 4 away from the display panel 3 is provided with a plurality of base mounting holes 43, so that the base 6 is fixedly connected to the display box 4 by bolts, see Fig. 9 The base 6 is a rectangular parallelepiped structure with a hollow interior. One side of the base 6 is inclined and opened, and the other side is provided with a wire port 61 adapted to the cable 15, so that the cable can pass through the wire port 61, and a waterproof interface component is installed on the wire port 61. The base 6 includes an angle adjustment component for adjusting the orientation of the display box 4. A first sealing gasket is provided between the base 6 and the display box 4, and a second sealing gasket is provided between the window glass 8 and the display box 4 to ensure the sealing effect at the joint.
[0038] See also Figure 8 The upper and lower side walls of the display frame 5 are provided with a plurality of first connection holes 51 adapted to the display panel 3, and the left and right side walls thereof are provided with a plurality of second connection holes 52 adapted to the display panel 3 and the display box 4. The display frame 5 can be used to fasten the display panel 3 and the display box 4 together to form an integral structure.
