A rib plate 7 is fixedly connected to one side of the rear end of the limiting bracket 6, and the rear end of the rib plate 7 is fixedly connected to the fixing frame 1. A cross brace 8 is fixedly connected between the front ends of the two left and right limiting brackets 6. The limiting brackets 6 with rib plate 7 and cross brace 8 are used for further limiting support of the LED display body 9 so as to stabilize the LED display body 9.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, further, the front end of the fixing frame 1 is provided with the LED display body 9, and the upper rear end of the LED display body 9 is provided with the upper insert sleeve 12, which is fitted and connected with the upper insert rod 3. The upper end of the upper insert sleeve 12 is provided with an opening 13, and the opening 13 is movably connected with the limiting insert shaft 14. The bottom end surface of the limiting insert shaft 14 is inclined, and the bottom end of the limiting insert shaft 14 is fitted and connected with the limiting insert hole 4. The upper end of the limiting insert shaft 14 is fixedly connected with the end strip 15, and the bottom end of the end strip 15 is fixedly connected to the left and right sides. All are fixedly connected with springs 16, and the bottom end of spring 16 is fixedly connected to upper sleeve 12. A pull rod 17 with a "U" shaped structure is fixedly connected to the upper end of spring 16. A lower sleeve 18 is provided at the bottom rear end of the fixing bracket 1, and the lower sleeve 18 is fitted with the lower rod 5. Fixing plates 10 are fixedly connected to the front ends of both upper sleeve 12 and lower sleeve 18, and the fixing plates 10 are fixedly connected to the LED display body 9 via four fixing screws 11. The LED display body 9 is installed with... At this time, by engaging the upper sleeve 12 with the upper rod 3 and engaging the lower sleeve 18 with the lower rod 5, the initial positioning and installation of the LED display body 9 and the fixing frame 1 can be completed. During the installation process, when the bottom end of the inclined surface of the limiting shaft 14 just begins to contact the upper part of the front end of the inclined surface of the upper rod 3, the bottom end of the inclined surface of the limiting shaft 14 is subjected to pressure and can temporarily retract upward into the opening 13, thereby driving the spring 16 to stretch upward elastically. When the upper sleeve 12 and the upper rod 3 are engaged in place, the limiting shaft 14... After being aligned with the limiting insertion hole 4, the bottom end of the limiting insertion shaft 14 can be inserted into the limiting insertion hole 4 under the rebound force of the spring 16, so as to further limit and fix the upper insertion sleeve 12 and the upper insertion rod 3. When disassembling the LED display body 9, the limiting insertion shaft 14 is lifted by the pull bar 17, so that the bottom end of the limiting insertion shaft 14 is disengaged from the limiting insertion hole 4, thereby releasing the limiting and fixing state of the upper insertion sleeve 12 and the upper insertion rod 3. Then, the LED display body 9 can be further removed by moving forward. The operation is simple, convenient and quick.

[0028] In this embodiment, the present invention has an upper insertion rod 3 and a lower insertion rod 5 at the front end of the fixing frame 1, and an upper insertion sleeve 12 and a lower insertion sleeve 18 at the rear end of the LED display body 9. Through the insertion and cooperation of the upper insertion sleeve 12 with the upper insertion rod 3 and the insertion and cooperation of the lower insertion sleeve 18 with the lower insertion rod 5, the LED display body 9 can be initially positioned and installed on the fixing frame 1 fixed to the wall. At the same time, through the cooperation of the upper insertion sleeve 12 upper limit insertion shaft 14 with the upper insertion rod 3 upper limit insertion hole 4, the LED display body 9 can be further fixed and positioned, so as to complete the fixed installation of the LED display body 9 on the wall.

[0029] With the above-mentioned structure, when the LED display body 9 needs to be removed for inspection and maintenance in the future, the end bar 15, spring 16 and limiting shaft 14 can be lifted directly by the pull bar 17, so that the bottom end of the limiting shaft 14 can be disengaged from the limiting insertion hole 4, releasing the limiting and fixing state of the upper insertion sleeve 12 and the upper insertion rod 3. Then, the LED display body 9 can be moved forward to remove the LED display body 9 for subsequent maintenance operations. After the maintenance is completed, the LED display body 9 can be quickly installed on the fixing frame 1 in the above manner. The operation is simple, convenient and quick, and the use is better.

[0030] The usage process and working principle of this utility model are as follows: When the LED display body 9 needs to be disassembled for maintenance, the pull bar 17 on the upper sleeve 12 lifts the end bar 15, spring 16, and limiting shaft 14, causing the bottom end of the limiting shaft 14 to disengage from the limiting insertion hole 4 on the upper rod 3, thereby releasing the limiting and fixing state between the upper sleeve 12 and the upper rod 3. Then, the LED display body 9 can be disassembled by moving it forward relative to the fixing frame 1 for subsequent maintenance. After maintenance, the upper sleeve 12 is fitted with the upper rod 3, and the lower sleeve 18 is fitted with the lower rod 5, thus completing the initial positioning and installation of the LED display body 9 with the fixing frame 1 fixed to the wall. During this process, the upper sleeve 12 is positioned at the opening. When the bottom end of the inclined surface of the limiting insert shaft 14 inside 13 just begins to contact the upper part of the front end of the inclined surface of the upper insert rod 3, the bottom end of the inclined surface of the limiting insert shaft 14 can temporarily retract upward into the opening 13 after being squeezed, and drive the end strip 15 and the pull strip 17 to move upward and the spring 16 to stretch upward elastically. When the upper insert sleeve 12 and the upper insert rod 3 are inserted into place, the limiting insert shaft 14 on the upper insert sleeve 12 is aligned with the limiting insertion hole 4 on the upper insert rod 3. Under the rebound force of the spring 16, the pull strip 17, the end strip 15 and the limiting insert shaft 14 can rebound downward and reset on their own. The bottom end of the limiting insert shaft 14 can be inserted into the limiting insertion hole 4 to achieve further limiting and fixing of the upper insert sleeve 12 and the upper insert rod 3, thereby completing the fixed installation of the LED display body 9 and the fixing bracket 1 fixed on the wall. The operation is simple, convenient and quick.
