The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Reference Figure 1-3 A road sign convenient for replacing advertisements comprises a road sign frame 1, a first round rod 2 is fixed to the inner walls of both sides of the bottom end of the road sign frame 1, a U-shaped box 3 is rotatably penetrated on the outer wall of the first round rod 2, a group of fixing plates 4 are fixed to the tops of both ends of the U-shaped box 3, each group of fixing plates 4 is rotatably penetrated with a same connecting shaft 5, a U-shaped plate 6 is fixed to the tops of the two connecting shafts 5, a billboard 7 is arranged on the side where the two U-shaped plates 6 are close to each other, a fixing box 8 is fixed to the top of the billboard 7, a mounting groove 9 is opened on one side of the fixing box 8, a second round rod 10 is fixed in the mounting groove 9, a transmission belt 11 is fixed on the second round rod 10, due to the use of The two connecting shafts 5 are squeezed to rotate when the billboard 7 is placed in the U-shaped box 3, and the two connecting shafts 5 rotate to drive the two U-shaped plates 6 to approach the billboard 7 until the billboard 7 is clamped, and the motor 13 is used to drive the third round rod 12 to rotate the winding transmission belt 11 to pull up the billboard 7. Therefore, the technical means effectively solves the problems raised in the background technology that it is very troublesome to replace the advertisements on the road signs, the operation is time-consuming and labor-intensive, the workload of the staff is increased, the number of road sign advertisements on the road is large, and the replacement efficiency is low, thereby achieving the technical effect of reducing the difficulty of installation, saving time and labor, reducing the workload of the staff, and improving the installation efficiency.

[0021] In this embodiment, the connecting shaft 5 is rotatably connected to the U-shaped box 3 .

[0022] In this embodiment, a third round rod 12 is fixed to one end of the transmission belt 11 away from the second round rod 10 , a motor 13 is fixed to one end of the third round rod 12 away from the transmission belt 11 , and a protective box 14 is fixed to the road sign frame 1 at the position of the motor 13 .

[0023] In this embodiment, a limit plate 18 is fixed to the top inner wall of the road sign frame 1, an inclined plate 16 is fixed to the side of the bottom end of the road sign frame 1 away from the protection box 14, a mounting plate 15 is fixed to the bottom of the road sign frame 1, and a mounting column 17 is fixed to the bottom of the mounting plate 15.

[0024] In this embodiment, the motor 13 is fixedly disposed in the protection box 14 , and the output shaft of the motor 13 rotates through the protection box 14 to be fixedly connected to the third round rod 12 .

[0025] In this embodiment, the limiting plate 18 is matched with the fixing box 8 , and the inclined plate 16 is matched with the U-shaped box 3 .

[0026] Working principle: When in use, install the road sign frame 1 on the mounting column 17, then install the advertisement to be displayed on the billboard 7, and then put the billboard 7 into the U-shaped box 3. The U-shaped box 3 is restricted by the inclined plate 16 so that it will not collapse when the billboard 7 is placed. When the billboard 7 is placed into the U-shaped box 3, the two connecting shafts 5 will be squeezed to rotate. The two connecting shafts 5 respectively drive the two U-shaped plates 6 to rotate close to the billboard 7. When the billboard 7 is completely placed in the U-shaped box 3, the two U-shaped plates 6 will tightly clamp the billboard 7. , then install the fixed box 8 on the billboard 7, and then start the motor 13.
