[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figure 1-4 The tunnel information display device shown includes an information display screen 2 installed at the top of the tunnel 1, and a first electric telescopic rod 3. The first electric telescopic rod 3 is vertically embedded in the top of the tunnel 1. Adaptive connection components 5 are installed on both opposite sides of the information display screen 2, and the information display screen 2 is detachably connected to the bottom output end of the first electric telescopic rod 3 through the adaptive connection components 5.

[0026] Regarding the aforementioned adaptive connection component 5, specifically, as follows: Figure 3 and Figure 4 As shown, the adaptive connection assembly 5 includes a mounting block 51, a connecting block 52, and a scissor connector 53. The mounting block 51 is fixed to the information display screen 2. The connecting block 52 is fixed to the end of the mounting block 51 away from the information display screen 2 through the scissor connector 53, which facilitates the installation of information display screens 2 of different lengths. The end of the connecting block 52 away from the scissor connector 53 is slidably connected to the bottom output end of the first electric telescopic rod 3. Specifically, the bottom output end of the first electric telescopic rod 3 is fixed with a limit slider 7. The side end of the connecting block 52 is provided with a limit groove 5201 for the vertical sliding installation of the limit slider 7. The limit slider 7 is slidably connected to the limit groove 5201 from bottom to top. The horizontal cross-section of the limit groove 5201 and the limit slider 7 is a T-shaped mutual limiting design.

[0027] The scissor connector 53 is fitted with a flexible protective sleeve 54 on its outer side. The flexible protective sleeve 54 is fixed between the mounting block 51 and the connecting block 52. The flexible protective sleeve 54 can provide a certain degree of protection for the scissor connector 53.

[0028] The scissor connector 53 can adopt a conventional scissor connection structure in the prior art. In order to prevent the information display screen 2 from shaking due to the movement of the scissor connector 53, the scissor connector 53 can adopt a conventional damping scissor connection structure.

[0029] It should be further noted that the scissor connector 53 described above can also adopt other telescopic structures conventional in the prior art, such as conventional telescopic rods with adjustment knobs (not shown in the figure).

[0030] The top of the information display screen 2 is electrically connected to an external power source and communication equipment via an automatic retractable electrical connection assembly 4. Specifically, the automatic retractable electrical connection assembly 4 includes a cable 41 and a spring tube 42. The information display screen 2 is electrically connected to the external power source and communication equipment via the cable 41. The spring tube 42 is sleeved on the outside of the cable 41 and can be detachably fixed between the information display screen 2 and the inner top of the tunnel 1. The cable 41 located inside the spring tube 42 is spiral-shaped, which can well adapt to the lifting and lowering of the information display screen 2.

[0031] In addition, an anti-accidental contact component 6 is installed at the inner top of tunnel 1 to prevent the first electric telescopic rod 3 from being accidentally extended. Specifically, the anti-accidental contact component 6 includes a second electric telescopic rod 61 and a limiting plate 62. The second electric telescopic rod 61 is horizontally fixed to the inner wall of tunnel 1, and the limiting plate 62 is fixed to the output end of the second electric telescopic rod 61. Under normal operating conditions, the limiting plate 62 is located directly below the limiting slider 7 to limit the limiting slider 7. Before the first electric telescopic rod 3 needs to be extended, the limiting plate 62 needs to be moved away using the second electric telescopic rod 61. Accordingly, the second electric telescopic rod 61 and the first electric telescopic rod 3 are controlled by different controllers or control buttons, which can effectively prevent accidental contact from causing the first electric telescopic rod 3 to move downward. In actual application, a pressure sensor can be added to the top surface of the limiting plate 62 to detect whether the limiting slider 7 is pressed down. When accidental contact causes the limiting slider 7 to be pressed down, the pressure sensor detects that the pressure exceeds its preset threshold and controls the first electric telescopic rod 3 to stop moving through the controller.

[0032] The working principle of this utility model is as follows: Under normal operating conditions, the limiting plate 62 is located directly below the limiting slider 7, which limits the limiting slider 7. Before the first electric telescopic rod 3 needs to be extended, the limiting plate 62 needs to be moved away using the second electric telescopic rod 61. After that, the information display screen 2 is moved down using the first electric telescopic rod 3, and the staff can directly inspect and maintain the information display screen 2 on the ground.

[0033] When the information display screen 2 needs to be replaced, simply pull the information display screen 2 upwards manually to disengage the limit slider 7 from the limit groove 5201.

[0034] Finally, it should be noted that the above description is only an embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
