[0023] Please see Figures 1-4A bracket device for road traffic signs includes a bracket support rod 1, and an extension mechanism 2 is provided above the bracket support rod 1.

[0024] The bottom end of the bracket support rod 1 is fixedly connected to a fixed base plate 3, and the outer surface of the bracket support rod 1 is fixedly connected to a reinforcing ring 4. The bottom surface of the reinforcing ring 4 is fixedly connected to the upper surface of the fixed base plate 3. The fixed base plate 3 enables the bracket support rod 1 to be vertically supported on the horizontal ground, while the reinforcing ring 4 improves the connection stability between the bracket support rod 1 and the fixed base plate 3.

[0025] The fixed base plate 3 has internal threaded connections with circumferentially arranged fixing bolts 5. The bottom end of each fixing bolt 5 passes through the fixed base plate 3 and extends to the bottom of the fixed base plate 3. By drilling threaded holes corresponding to the fixing bolts 5 at the required positions, the fixing bolts 5 can easily pass through the fixed base plate 3 and be threadedly connected to the drilled threaded holes, thereby fixing the fixed base plate 3 in the required positions.

[0026] Each fixing bolt 5 has an installation ring 6 fitted on its outer surface. The bottom surface of each installation ring 6 is in contact with the upper surface of the fixing base plate 3. The installation ring 6 can buffer the impact force between the fixing bolt 5 and the fixing base plate 3, thereby improving the service life of the fixing bolt 5.

[0027] The extension mechanism 2 includes a protective box 201. The bottom surface of the protective box 201 is fixedly connected to the top end of the bracket support rod 1. The upper surface of the fixed base plate 3 is fixedly connected with reinforcing rods 7 arranged in a circular pattern at equal intervals. The top end of each reinforcing rod 7 is fixedly connected to the bottom surface of the protective box 201. The outer surface of each reinforcing rod 7 is fixedly connected with a fixing ring 8. The bottom surface of each fixing ring 8 is fixedly connected to the upper surface of the fixed base plate 3. By utilizing the supporting effect of the reinforcing rods 7 and the fixing rings 8, the protective box 201 can be stably supported, thereby improving the support stability of the protective box 201.

[0028] A rotating motor 203 is fixedly connected to the inner bottom wall of the protective box 201. A main rotating gear 204 is fixedly connected to the output end of the rotating motor 203. A first threaded shaft 206 is rotatably connected inside the protective box 201. A driven rotating gear 205 is fixedly connected to the outer surface of the first threaded shaft 206. The driven rotating gear 205 meshes with the main rotating gear 204. Limiting plates 202 are fixedly connected to both sides of the protective box 201. A first threaded slider 207 is threadedly connected to the outer surface of the first threaded shaft 206. The inner wall of one of the limiting plates 202 contacts the outer surface of the first threaded slider 207. Two limiting strips 9 are fixedly connected to both sides of the protective box 201. The side of the two limiting strips 9 that are close to each other contacts the front and back of the first threaded slider 207, respectively. By setting four limiting strips 9, the limiting plates 202 are used to limit the movement of the first threaded slider 207, thereby improving the movement stability of the first threaded slider 207.

[0029] A snap-fit ​​strip 208 is fixedly connected to the upper surface of the first threaded slider 207. A traffic sign 209 is snapped into the inside of the snap-fit ​​strip 208. The second threaded slider 11 is provided on one side of the two limit strips 9 that are close to each other. The inner wall of another limit plate 202 is in contact with the outer surface of the second threaded slider 11. The right end of the first threaded shaft 206 is fixedly connected to the second threaded shaft 10. The second threaded shaft 10 is rotatably connected to the inside of the protective box 201. The second threaded shaft 10 is threadedly connected to the inside of the second threaded slider 11. A counterweight 12 is fixedly connected to the upper surface of the second threaded slider 11. The rotation of the first threaded shaft 206 drives the second threaded shaft 10. Since the second threaded shaft 10 and the second threaded slider 11 cooperate, the second threaded slider 11 can be used to move the counterweight 12, thereby adjusting the center of gravity of the bracket device.

[0030] The working principle of this utility model is as follows: In use, the rotating motor 203 is first connected to a power source. When the bracket device is needed to support road traffic signs, it is first manually placed at the required location on both sides of the road. A foundation concrete is provided at the required location, and threaded holes corresponding to the fixing bolts 5 are drilled in the foundation concrete. This allows the fixing bolts 5 to pass through the fixed base plate 3 and connect to the drilled holes, thus fixing the bracket device in the required position. The protective box 201 is fixed to the top of the bracket support rod 1, and the support structure composed of multiple reinforcing rods 7 and fixing rings 8 is used to improve the support stability of the protective box 201. By controlling the power supply of the rotating motor 203 inside the protective box 201, the rotating motor 203 can drive the main rotating gear 204 to rotate. Through the meshing between the main rotating gear 204 and the driven rotating gear 205, the first threaded shaft 206 and the second threaded shaft 10 fixed to the inner wall of the driven rotating gear 205 can rotate synchronously. Because the first threaded shaft 206 and the second threaded shaft 10... The thread pitches of the threaded shafts 10 are different. The first threaded shaft 206 and the second threaded shaft 10 are connected by external threads to a first threaded slider 207 and a second threaded slider 11. This allows the first threaded shaft 206 and the first threaded slider 207, and the second threaded shaft 10 and the second threaded slider 11, to rotate and move the first threaded slider 207 and the second threaded slider 11 in different directions. The traffic sign 209 is manually engaged with the locking strip 208 fixed to the first threaded slider 207, facilitating its movement. The counterweight 12 fixed to the second threaded slider 11 balances the extended weight of the traffic sign 209, ensuring the center of gravity of the bracket remains centered, thus improving its stability. Moving the traffic sign 209 also reduces obstruction from roadside vegetation, enhancing the practicality of the bracket.
