[0051] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0052] like Figure 2 As shown, it includes a display board 1 installed on a road sign. In this embodiment, the display board 1 adopts an LED display board 1. The central control unit of the road sign displays the destination location information on the display board 1 and controls the indication direction of the display board 1 to provide guidance for pedestrians.

[0053] When the conventional LED display board 1 is fixed, Figure 1 As shown, the lug 101 of the display sign 1 is fixed to the road sign by screws, which makes it inconvenient to disassemble, assemble and maintain the display sign 1.

[0054] In this embodiment, if Figure 5 and Figure 6 As shown, it includes a positioning plate 2 for fixing the display board 1. Specifically, the display board 1 and the positioning plate 2 are fixedly connected by bolts. Here, a countersunk hole is provided on the positioning plate 2, and the end of the bolt is located in the countersunk hole to prevent the bolt from protruding from the positioning plate 2. The positioning plate 2 and the display board 1 are replaced directly on the road sign as a whole.

[0055] In order to facilitate the power supply to the display board 1, in this embodiment, Figure 5 and Figure 6 As shown, a plug interface 22 is provided on the positioning plate 2 , wherein the plug interface 22 is a through hole, and the power contact 102 on the display board 1 is plugged into the plug interface 22 , and power can be supplied to the display board 1 through the plug interface 22 .

[0056] In order to quickly install the display board 1 on the road sign, it also includes a base 3, wherein a dovetail groove 31 is provided on the base 3, and a dovetail tenon 21 is provided on the positioning plate 2. When the positioning plate 2 is installed, the dovetail tenon 21 can be inserted into the dovetail groove 31.

[0057] Specifically, the dovetail groove 31 and the dovetail tenon 21 are arranged along the length direction of the base 3 .

[0058] In this embodiment, the base 3 is a square tube structure, and the power supply contact 4 and the power plug 8 electrically connected to the power supply contact 4 are slidably connected inside the base 3. Specifically, a mounting port 311 is provided in the dovetail groove 31, and the side wall of the power supply contact 4 is slidably connected to the side wall of the mounting port 311. When the dovetail tenon 21 is inserted into the inside of the dovetail groove 31, the power supply contact 4 is inserted into the plug port 22, so that the power supply contact 4 is electrically connected to the power contact 102, thereby supplying power to the display board 1.

[0059] like Figure 8 As shown, when the dovetail tenon 21 is not inserted into the dovetail groove 31, the power contact 4 extends into the dovetail groove 31. When the dovetail tenon 21 is inserted into the dovetail groove 31, in order to prevent the power contact 4 from affecting the insertion of the dovetail tenon 21, in this embodiment, as shown in FIG. Figure 7 、 Figure 8 and Figure 9 As shown, the side wall of the dovetail 21 is provided with a third guiding slope 211 , and the side wall of the power contact 4 is provided with a second guiding slope 41 adapted to the third guiding slope 211 . Specifically, the cross section of the power contact 4 is an isosceles trapezoid.

[0060] When the positioning plate 2 is inserted into the dovetail groove 31, the third guide slope 211 at the end of the dovetail tenon 21 first abuts against the second guide slope 41 on the power contact 4, thereby pushing the power contact 4 away from the display board 1, avoiding the power contact 4 affecting the installation of the positioning plate 2. When the plug interface 22 on the dovetail tenon 21 is aligned with the power contact 4, the power contact 4 is inserted into the plug interface 22, thereby realizing the electrical connection between the power contact 4 and the power contact 102.

[0061] In order to enable the positioning plate 2 to be removed from the dovetail groove 31, in this embodiment, as shown in FIG. Figure 7 and Figure 9As shown, a first guide slope 221 is provided on the inner wall of the plug interface 22, wherein the first guide slope 221 opens outward and is adapted to the second guide slope 41. When the positioning plate 2 is pulled out of the dovetail groove 31, the first guide slope 221 abuts against the second guide slope 41, thereby pushing the power contact 4 toward the inside of the base 3, so that the power contact 4 is disengaged from the plug interface 22, thereby completing the removal of the positioning plate 2.

[0062] When the positioning plate 2 is in the process of moving, in order to enable the power contact 4 to be reset and extend into the dovetail groove 31, in this embodiment, as shown in FIG. Figure 7 As shown, a spring 6 is further included, wherein one end of the spring 6 abuts against the power supply contact 4 , and the other end of the spring 6 abuts against the base 3 .

[0063] When the dovetail tenon 21 contacts the power contact 4, the power contact 4 will be pushed into the base 3 and the spring 6 will be compressed. When the power contact 4 is aligned with the plug interface 22, the spring 6 pushes the power contact 4 to be plugged into the plug interface 22, so that the power contact 4 is electrically connected to the power contact 102.

[0064] In order to solve the problem that the display board 1 is short-circuited due to rainwater on the base 3, in this embodiment, Figure 5 、 Figure 6 and Figure 9 As shown, the top side wall of the base 3 is provided with a protective rib 32 extending laterally, wherein the bottom wall of the protective rib 32 is provided with an insert rib 321, and the insert rib 321 is arranged along the length direction of the base 3. The positioning plate 2 is provided with an insert groove 23. When the dovetail tenon 21 of the positioning plate 2 is inserted into the dovetail groove 31, the insert rib 321 is inserted into the insert groove 23.

[0065] When rainwater on the base 3 flows outward along the protective rib 32 , the insertion rib 321 is used to change the direction of the water flow to prevent the water from flowing toward the display sign 1 .

[0066] Specifically, in this embodiment, Figure 9 As shown, the positioning plate 2 is also provided with a guide groove 24 located on the lower side of the plug-in groove 23. The guide groove 24 is connected to the end wall of the positioning plate 2, and also includes a drainage hole 25 that connects the plug-in groove 23 with the guide groove 24. When rainwater flows into the inside of the plug-in groove 23 through the plug-in rib 321, the rainwater will flow into the inside of the guide groove 24 through the drainage hole 25. Finally, the rainwater is retained from the end wall of the positioning plate 2 to prevent the rainwater from contacting the line, thereby solving the short circuit problem.

[0067] Specifically, in this embodiment, Figure 4 and Figure 6As shown, a positioning tube 7 is provided in the inner cavity of the base 3 , wherein the power contact 4 and the spring 6 are mounted on the positioning tube 7 , wherein the power plug 8 is mounted on the positioning tube 7 , and the positioning tube 7 can be used to arrange the circuit.

[0068] A guide rib 33 is provided on the inner wall of the inner cavity of the base 3, and a guide groove 71 is provided on the outer wall of the positioning tube 7. When installing the positioning tube 7, align the guide rib 33 with the guide groove 71, and then insert the positioning tube 7 into the inner cavity of the base 3 to achieve the positioning of the positioning tube 7.

[0069] In this embodiment, if Figure 4 As shown, a blocking cover 5 is also included. The blocking cover 5 is installed on the end wall of the base 3, and the dovetail tenon 21 of the positioning plate 2 is encapsulated in the dovetail groove 31.

[0070] Specifically, a slot 72 is provided on the positioning tube 7, and a positioning block 51 is provided on the blocking cover 5. When the blocking cover 5 is installed, the positioning block 51 is inserted into the slot 72, and then the positioning screw 9 is used to pass upward from the bottom wall of the base 3 into the slot 72, and then threadedly connected with the positioning block 51 to fix the blocking cover 5 and the positioning tube 7 on the base 3.

[0071] At this time, the positioning screw 9 can limit the movement of the positioning tube 7 in the length direction of the base 3, and the blocking cover 5 can also prevent rainwater from penetrating inward from the end wall of the base 3, thereby improving the safety of the installation of the display board 1.

[0072] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved. This is not a limitation herein.

[0073] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0074] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
