The mounting box is provided with a retractable shielding mechanism, and the shielding mechanism and the fence are detachably connected.

[0006] Furthermore: the shielding mechanism includes a connecting rod rotatably connected to the mounting box and a shielding cloth wound around the connecting rod. Both ends of the connecting rod are provided with springs, and the free end of the shielding cloth is provided with a connector. The connector is located on the outside of the mounting box, and a hanging rod is provided on the outside of the connector.

[0007] Furthermore, the upper end of the fence is provided with a hook that cooperates with the hanging rod, and the hook is set at an outward angle.

[0008] Furthermore: an extension rod is slidably fitted inside the vertical post of the fence. The extension rods are symmetrically arranged inside the fence and slide up and down. A top rod is fixed to the upper end of the two extension rods. A fixing button for fixing the extension rod is provided on the inner side of the vertical post.

[0009] Furthermore, the fence is a closed frame structure formed by welding together several vertical and horizontal bars.

[0010] Furthermore: the hook is located on the outer edge of the fence, with its opening facing outwards.

[0011] This utility model provides a traffic information LED display device. Compared with the prior art, it has the following advantages:

[0012] This traffic information LED display device features a retractable shielding mechanism for quick sun and rain protection, an adjustable extension rod to increase working space, and an outward-sloping hook to prevent equipment from getting caught. The overall structure is simple and reliable, significantly improving the comfort and safety of maintenance operations. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-6This utility model provides a technical solution: a traffic information LED display device; specifically composed of a support rod 1 and an LED display screen 2. The LED display screen 2 is fixed to one side of the upper end of the support rod 1. A support mesh plate 3 is fixed to the lower end of the back side of the LED display screen 2, providing a place for people to stand and walk. A fence 4 is fixed to the outer end of the support mesh plate 3. The fence 4 is made up of multiple vertical bars and multiple horizontal bars connected by welding. Operators and maintenance personnel can perform operations within the fence 4 to maintain the wiring or screen on the back side of the LED display screen 2. This is existing known technology and will not be described in detail here. A mounting box 5 is fixed to the upper end of the back side of the LED display screen 2. A shielding mechanism is provided inside the mounting box 5. The shielding mechanism is matched and connected to the fence 4. The shielding mechanism shields the operating area of ​​the personnel, avoiding direct sunlight and rain interference, thus providing a better environment for maintenance and repair.

[0022] The shielding mechanism includes a shielding cloth 7 and a connecting rod 6. The connecting rod 6 is rotatably mounted inside the mounting box 5, and both ends of the connecting rod 6 are fixed with a spring. The other end of the spring is fixedly connected to the inner wall of the mounting box 5. The working principle of the spring is a known technology and will not be described in detail here. The shielding cloth 7 and the connecting rod 6 are wound up. One end of the shielding cloth 7 is fixedly connected to the connecting rod 6, and the other end of the shielding cloth 7 is fixed with a connector 8. The connector 8 is located at the outer end of the mounting box 5. A hanging rod 9 is fixed at the outer end of the connector 8, and a hook 11 is fixed at the upper end of the fence 4. The hanging rod 9 and the hook 11 are matched and hooked together. The worker pulls the connector 8 outward through the hanging rod 9, and the connector 8 pulls the shielding cloth 7 out. The shielding cloth 7 can shield the vertical upper area of ​​the supporting mesh plate 3, providing a better working environment.

[0023] An extension rod 12 is inserted inside the vertical post of the fence 4. A top rod 13 is fixed at the upper end of the extension rod 12. A fixing button 10 is threaded to the inner end of the vertical post of the fence 4. The fixing button 10 passes through the vertical post and abuts against the extension rod 12 inside. This allows the extension rod 12 to be supported upwards according to the actual use, and the middle part of the cover 7 to be lifted by the top rod 13 to form a larger internal space.

[0024] The hook 11 is located at the outer end of the fence 4 and is set at an angle to the outside, which can prevent it from getting caught on the staff's tool bag or safety strap, thus providing a better safe working environment.
