[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0023] Reference Figures 1-4 As shown, a special evacuation sign for fire emergency response in highway tunnels includes two display panels 1, which are hinged together. Each display panel 1 is provided with a transparent clip 1.1, and the two transparent clips 1.1 are connected by a flexible part 1.10.
[0024] Each display panel 1 has a telescopic leg 1.2 slidably connected to one side.
[0025] Each telescopic leg 1.2 is connected to its corresponding display panel 1 via a locking unit. After the telescopic leg 1.2 moves to a preset position, the locking unit locks and limits the telescopic leg 1.2.
[0026] The locking unit includes an abutment and a plug. The abutment is disposed on each telescopic leg 1.2 corresponding to it, and the plug is slidably connected to each display panel 1.
[0027] The connector includes a sliding connection to the upper limit pin 1.13 of each display panel 1, and each limit pin 1.13 is connected to the display panel 1 by a spring 1.12.
[0028] The abutment includes a wedge-shaped abutment portion 1.21 fixedly connected to each telescopic leg 1.2, and each wedge-shaped abutment portion 1.21 has a limiting hole 1.210 adapted to the limiting pin 1.13.
[0029] Specifically, such as Figure 1 As shown, two display panels 1 are hinged together on one side. A matching frame is fixedly connected to the back of each display panel 1. A storage space for storing each sign is formed between the frames of each light-emitting panel. A transparent clip bag 1.1 is fixedly connected to the front of each display panel 1 by adhesive or hot-melt. The two transparent clip bags 1.1 are connected by a flexible part 1.10, which can be made of silicone with good elasticity. A space for placing the sign is formed between the transparent bag and the display panel 1. A light-emitting component, which is an LED light strip, is embedded in the front of the display panel 1. A power supply is embedded in the display panel 1 to power the LED light strip.
[0030] A blind hole adapted to the telescopic leg is provided at the bottom of each display panel 1. A sliding groove adapted to the blind hole is provided at the position of the wedge-shaped ground contact part on the inner wall of the blind hole. A round hole adapted to the limiting pin 1.13 is provided at the position of the sliding groove on the front of each display panel 1. The round hole is connected to the sliding groove. A spring 1.12 is fixedly connected to the round hole of each display panel 1. The other end of the spring 1.12 is fixedly connected to the limiting pin 1.13. A limiting hole 1.210 adapted to the limiting pin 1.13 is provided on the telescopic leg 1.2 at the wedge-shaped abutment part 1.21.
[0031] This utility model provides a special evacuation indicator sign for fire emergency response in highway tunnels. It consists of two display panels 1 hinged together, and a transparent clip 1.1 fixedly connected to the display panels 1. The two transparent clips 1.1 are connected by a flexible part 1.10, which allows users to set different types of indicator signs as needed, thereby improving the utilization rate of the indicator device.
[0032] When using, such as Figures 1-2 As shown, this utility model has two usage states. When the number of characters in the instruction is small, it can be used as follows: Figure 2 As shown in the diagram, when the number of characters in the instruction is large, state 1 can be used. When using state 1, the user first moves the two wedge-shaped ground contact parts from inside the light panel to the telescopic leg 1.2 until they abut against the limit pin 1.13. This causes the wedge-shaped contact part 1.21 to abut against the limit pin 1.13, allowing the limit pin 1.13 to slide on the display panel 1, causing the spring 1.12 to extend. When the upper limit hole 1.210 of the wedge-shaped contact part 1.21 is aligned with the limit pin 1.13, the limit pin 1.13 is inserted into the limit hole 1.210, thereby locking and limiting the telescopic leg 1.2. This can alert following vehicles in case of emergencies in the tunnel. Furthermore, since the display panel 1 is foldable and the telescopic leg 1.2 can be retracted, it is easy to carry and the instruction text can be changed according to different scenarios.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
