[0019] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model.
[0020] Some embodiments of the present utility model will be described below in conjunction with the accompanying drawings to provide a road sign. Embodiment
[0021] Combined Figures 1-3 As shown, a road sign provided by the utility model includes a mounting base 1. A support rod 2 is fixedly provided on the mounting base 1. A controller 201, a first connecting plate 202 and a second connecting plate 203 are fixedly provided on the support rod 2. An LED indicator screen 3 is fixedly provided on the controller 201. A protection plate 4 is fixedly provided on the second connecting plate 203. A chute 401 is provided on the protection plate 4. A break 402 is provided at the end of the chute 401. A three-stage hydraulic telescopic rod 5 is fixedly provided on the protection plate 4. A connecting rod 501 is fixedly provided on the telescopic end of the three-stage hydraulic telescopic rod 5. Limit plates 502 are fixedly provided at both ends of the connecting rod 501. Connecting rings 601 are rotatably provided at both ends of the connecting rod 501. A metal sign 6 is fixedly provided on the connecting ring 601. The connecting ring 601 is rotatably connected to the inner side surface of the limit plate 502. The diameter of the limit plate 502 is larger than the diameter of the connecting ring 601. The connecting rod 501, the limit plates 502, the metal sign 6 and the connecting ring 601 are slidably connected in the chute 401. The middle of the connecting rod 501 is fixedly connected to the top of the third telescopic end of the three-stage hydraulic telescopic rod 5. The width of the connecting rod 501 is larger than the width of the metal sign 6. The length of the metal sign 6 is smaller than the length of the chute 401. The bottom of the metal sign 6 is slidably connected to the bottom of the chute 401. The length and width of the metal sign 6 are larger than the length and width of the LED indicator screen 3. The length and width of the protection plate 4 are larger than the length and width of the metal sign 6. The protection plate 4 and the metal sign 6 are located above the metal sign 6. Wires are provided in the support rod 2, the first connecting plate 202 and the second connecting plate 203. The LED indicator screen 3 is connected to the controller 201 through a wire. The three-stage hydraulic telescopic rod 5 is connected to the controller 201 through a wire. The indicating surface of the metal sign 6 faces the lower surface of the protection plate 4.
[0022] Specifically, a support rod 2 is fixedly installed in the middle of the upper surface of the mounting base 1 to improve the stability of the support rod 2. A controller 201 is fixedly installed on the support rod 2 to facilitate the staff to control and adjust the LED display screen 3 and the three-stage hydraulic telescopic rod 5. A first connecting plate 202 and a second connecting plate 203 are fixedly welded on the support rod 2. The LED display screen 3 is fixedly connected to the first connecting plate 202, so that the LED display screen 3 can provide road information for the driver through the LED lamp group. A protective plate 4 is fixedly welded on the second connecting plate 203. The length and width of the protective plate 4 are greater than those of the LED display screen 3, and the protective plate 4 is located above the LED display screen 3 to provide protection for the LED display screen 3 and reduce the time of the LED display screen 3 being exposed to wind and sun. A three-stage hydraulic telescopic rod 5 is fixedly installed on the bottom side of the protective plate 4. The end of the telescopic end of the three-stage hydraulic telescopic rod 5 is fixedly welded with a connecting rod 501, and both ends of the connecting rod 501 are slidably connected in the chute 401 on the protective plate 4. Limit plates 502 are fixedly welded at both ends of the connecting rod 501. A connecting ring 601 is rotatably connected inside the limit plate 502, and the connecting ring 601 is rotatably connected to both ends of the connecting rod 501. Both the limit plate 502 and the connecting ring 601 are slidably connected in the chute 401. A metal sign 6 is fixedly welded on the connecting ring 601. When the three-stage hydraulic telescopic rod 5 pushes the connecting rod 501 to move, the connecting ring 601 and the metal sign 6 will slide along the chute 401. The diameter of the connecting ring 601 is smaller than that of the limit plate 502, so that the connecting ring 601 will not fall off the connecting rod 501. A break 402 is provided at the end of the chute 401. When the connecting rod 501 moves to the position of the break 402, the metal sign 6 will be located outside the break 402. Due to the gravity of the metal sign 6, the metal sign 6 will drive the connecting ring 601 to rotate around the connecting rod 501 and finally be in a vertical state, directly in front of the LED display screen 3. When there is a problem with the lamp group of the LED display screen 3, the metal sign 6 can be used as an alternative to provide road information for the driver. The indicating surface of the metal sign 6 faces the lower surface of the protective plate 4, so that when the metal sign 6 is in a vertical state, the indicating surface can be seen by the driver, thus avoiding the problem of reduced safety caused by inaccurate and untimely information transmission.
[0023] Working principle and usage process of the utility model: Firstly, under normal circumstances, the staff can provide the controller 201 to adjust the lamp group on the LED display screen 3, so as to display traffic information. When the lamp group on the LED display screen 3 has problems and cannot be repaired in time, the staff can use the controller 201 to control the start of the three-section hydraulic telescopic rod 5, thereby pushing the connecting rod 501, and then pushing the metal sign 6 and the connecting ring 601 to slide in the chute 401. When the connecting rod 501 reaches the position of the break 402, the three-section hydraulic telescopic rod 5 can be closed. At this time, the metal sign 6 will drive the connecting ring 601 to rotate due to the action of gravity, and finally will be vertically located directly in front of the LED display screen 3, thereby blocking the LED display screen 3. The indicating surface of the metal sign 6 will provide accurate traffic information for the driver again, thus ensuring the life safety of the driver. At the same time, the protection plate 4 will also provide protection for the LED display screen 3 and the metal sign 6, reducing the influence of wind, sun and rain, and thus extending the service life.
[0024] It should be understood that the above specific embodiments of the present utility model are only used for exemplary illustration or explanation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
