[0101] Embodiment 3:

[0102] This embodiment provides a community light box billboard, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0103] like Figure 1 and Figure 8 As shown, in this embodiment, the bottom of the light box body 1 is optimized to be provided with an adjustment mechanism 6 for adjusting the height, and the adjustment mechanism 6 includes:

[0104] The bottom plate 61 is located below the light box body 1;

[0105] There are a plurality of mounting holes 62, which are evenly spaced and opened on the bottom plate 61;

[0106] A protective shell 63 is arranged around the top of the bottom plate 61;

[0107] The electric push rod 64 is disposed inside the protective shell 63;

[0108] The connecting frame 65 is arranged at the bottom of the light box body 1;

[0109] The connecting plates 66 are arranged at the left and right ends of the front and rear sides of the connecting frame 65 , and the piston rod of the electric push rod 64 is connected to the connecting plates 66 .

[0111] When the height of the community light box billboard needs to be adjusted, the electric push rod 64 is activated, and its piston rod begins to extend and retract. The movement of the piston rod is transmitted to the bottom of the light box body 1 through the connecting plate 66, thereby adjusting the height of the light box. The user can control the movement of the electric push rod 64 to make the height of the light box reach the desired position to adapt to different scenes and needs. The design of the entire adjustment mechanism 6 is intended to simplify the light box height adjustment process, improve the flexibility and applicability of the light box, and better meet the diversity of community advertising needs.

[0112] Embodiment 4:

[0113] This embodiment provides a community light box billboard, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0114] like Figure 7 As shown, in this embodiment, it is optimized that the left and right sides of the interior of the light box body 1 are provided with sliding grooves 7 for the light box panels 3 to be slidably connected.

[0115] In the present technical scheme, the slide groove 7 is used to enable the light box board 3 to slide in the light box body 1. When the light strip needs to be fixedly installed, the user can move the light box board 3 out of the slide groove 7, and then fix the light strip on the light box board 3. After the light strip is installed, the user aligns the light box board 3 with the slide groove 7 and pushes the light box board 3 to move the light box board 3 along the slide groove 7 toward the inside of the light box body 1 until the light box board 3 is moved to a suitable position. There is damping between the light box board 3 and the slide groove 7, so that the light box board 3 is not easy to move at will. In this way, it is convenient to install the light strip on the light box board 3 to ensure the lighting effect of the billboard.

[0116] Embodiment 5:

[0117] This embodiment provides a community light box billboard, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0118] like Figure 3 As shown, in this embodiment, the optimization further includes a heat dissipation mechanism 8, and the heat dissipation mechanism 8 includes:

[0119] There are a plurality of heat dissipation holes 81, which are arranged at the bottom of the rain shield 41;

[0120] The installation groove 82 is provided at the bottom of the rain shield 41, and there are a plurality of the installation grooves 82;

[0121] An air guide housing 83 is disposed in the mounting groove 82;

[0122] The fan 84 is disposed in the air guide housing 83 and is located on the upper side of the light box body 1;

[0123] The power source 85 is used to provide power to drive the fan 84 to rotate.

[0124] In the present technical solution, the mounting groove 82 is located at the bottom of the rain shield 41 and is used to accommodate the air guide shell 83. The design of the air guide shell 83 can guide the air flow so as to effectively take away the heat. The heat dissipation hole 81 is used to discharge the heat in the light box body 1. The power source 85 is used to drive the fan 84 to rotate. The fan 84 faces the inside of the light box body 1 so as to guide the air to the area where heat dissipation is required. The fan 84 provides a heat dissipation effect. When the power source 85 is started, the power source 85 drives the fan 84 to start rotating forward to generate airflow. The airflow is guided to the inside of the light box body 1 to effectively blow away the heat and reduce the temperature generated by its operation. When the power source 85 drives the fan 84 to rotate in the opposite direction, negative pressure is generated, thereby absorbing the heat in the light box body 1 and guiding the heat to be discharged from the heat dissipation hole 81 through the air guide shell 83, so that the heat in the light box body 1 can be dissipated in time and effectively, thereby ensuring that the light bar maintains a stable operating temperature during long-term operation, extending its service life, and ensuring that its performance is not affected by heat.

[0125] The embodiments of the present application are described above in conjunction with the accompanying drawings.
