[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1 to 5 As shown, a traffic sign that is easy to replace includes a base 1. The base 1 is usually made of high-strength cast iron and has a large bottom area, which can enhance the stability of the entire traffic sign in the installation position and effectively resist the impact of natural factors such as wind and rain.

[0020] The top of the base 1 is fixedly connected to the storage tube 2 by welding. The storage tube 2 is made of stainless steel, which has good anti-rust properties and can effectively extend its service life. Its appearance is cylindrical and hollow inside, which not only provides protection for the internal adjustment components 3, but also plays a certain role in aesthetics, making it more in harmony with the surrounding environment.

[0021] The storage tube 2 has an adjustment component 3 inside.

[0022] The adjustment component 3 includes a slide cylinder 301 that is slidably connected to the inner wall of the storage cylinder 2. The slide cylinder 301 is made of aluminum alloy, which is lightweight and high-strength, making it easy to move while ensuring sufficient structural strength. The slide cylinder 301 is cylindrical.

[0023] A set of crossbars 4 are distributed on the outer surface of the slide cylinder 301. They are fixedly connected by welding to ensure the connection is firm. The crossbars 4 are made of rectangular steel pipes, which have high bending strength and can stably support the sign body 6. The outer surface of the crossbars 4 has T-shaped grooves that engage with the T-shaped clips that are fixed to the back of the sign body 6. This engagement method is simple to operate and facilitates quick installation and disassembly of the sign body 6. A set of limiting components 5 is provided at the rear of the crossbars 4 to limit the sign body 6 and ensure that it will not shake or shift during use.

[0024] The adjustment component 3 also includes a motor 302 fixedly installed on the inner wall of the storage tube 2. The motor 302 is a waterproof motor designed for outdoor work and can adapt to various harsh weather conditions.

[0025] An adjusting screw 303 is fixedly connected to the output end of the motor 302. The adjusting screw 303 is made of high-strength alloy steel and its surface has been finely processed, giving it good wear resistance and corrosion resistance. The outer surface of the adjusting screw 303 is rotatably connected to the inner wall of the storage cylinder 2 through a bearing. This connection method can reduce the friction during rotation, making the rotation of the adjusting screw 303 smoother and also improving its service life. The adjusting screw 303 is screwed to the slide cylinder 301.

[0026] When the motor 302 starts, it drives the adjusting screw 303 to rotate. Using the principle of screw transmission, the slide cylinder 301 moves up and down along the axial direction of the adjusting screw 303, thereby adjusting the height of the cross frame 4 and the sign body 6. This adjustment method has high precision and good stability, and can meet the height requirements of traffic signs in different scenarios.

[0027] A limiting slider 304 is fixedly connected to the outer surface of the slide cylinder 301. The limiting slider 304 is made of wear-resistant engineering plastic, which has good sliding performance and wear resistance. The outer surface of the limiting slider 304 is slidably connected to the inner wall of the storage cylinder 2. A set of limiting rods 305 are slidably connected to the inner wall of the storage cylinder 2. The limiting rods 305 are made of stainless steel, with a smooth surface and high strength and straightness. The two ends of the limiting rods 305 are fixedly connected to the inner wall of the storage cylinder 2 by welding or bolting to ensure its stability. The cooperation of the limiting slider 304 and the limiting rods 305 can effectively limit the rotation of the slide cylinder 301, so that the slide cylinder 301 can only move up and down along the direction of the limiting rods 305. This ensures the smoothness and accuracy of the adjustment process, avoids the slide cylinder 301 from deviating or shaking during the adjustment process, and thus improves the reliability of the entire traffic sign adjustment system.

[0028] The limiting component 5 includes a limiting frame 501 fixedly connected to the outer surface of the cross frame 4. The limiting frame 501 is made of steel plate stamping and has high structural strength and stability.

[0029] The inner wall of the limit frame 501 is slidably connected to the insertion rod 502. The insertion rod 502 is made of high-quality carbon steel and its surface is hardened to improve its hardness and wear resistance. The outer surface of the insertion rod 502 is slidably connected to the inner wall of the cross frame 4, and the insertion rod 502 is inserted into the inside of the sign body 6. In this way, the sign body 6 is fixed.

[0030] A baffle 503 is fixedly connected to the outer surface of the insertion rod 502. The baffle 503 is made of a circular steel plate with a diameter larger than that of the insertion rod 502, which can effectively prevent the insertion rod 502 from coming out of the limit frame 501.

[0031] A pull ring 504 is fixedly connected to the end of the insertion rod 502 away from the crossbar 4. The pull ring 504 is made of metal and is shaped to be easy for workers to hold and operate.

[0032] An elastic element 505 is sleeved on the outer surface of the insertion rod 502. The elastic element 505 is made of high-strength spring and has good elasticity and resilience. One end of the elastic element 505 is fixedly connected to the inner wall of the limit frame 501, and the other end of the elastic element 505 is fixedly connected to the outer surface of the baffle 503.

[0033] When it is necessary to replace the sign body 6, pull the pull ring 504, which causes the insertion rod 502 to slide within the limiting frame 501 and compress the elastic element 505, so that the insertion rod 502 is pulled out from inside the sign body 6. The old sign body 6 can then be removed. After the new sign body 6 is snapped onto the cross frame 4, release the pull ring 504. The elastic element 505 rebounds, pushing the insertion rod 502 into the new sign body 6 to complete the fixation. This design of the limiting component 5 is simple and convenient to operate, and can quickly realize the replacement of the sign body 6, improving work efficiency. At the same time, the elasticity of the elastic element 505 ensures the tightness of the connection between the insertion rod 502 and the sign body 6, ensuring the stability of the sign body 6 during use.

[0034] Working principle: When the traffic sign needs to be replaced, the motor 302 installed on the inner wall of the storage cylinder 2 is started. The output end of the motor 302 drives the adjusting screw 303 to rotate. Since the adjusting screw 303 is screwed to the slide cylinder 301, and the limiting slider 304 on the outer surface of the slide cylinder 301 slides on the limiting rod 305, the rotation of the slide cylinder 301 is restricted. Therefore, the slide cylinder 301 will move up and down along the direction of the limiting rod 305, thereby driving the crossbar 4 and the sign body 6 to descend to the appropriate height. At this time, pull Pulling ring 504 causes insert rod 502 to slide within limit bracket 501 and compress elastic element 505, allowing insert rod 502 to be pulled out from inside sign body 6, thus removing the old sign body 6. Then, the new sign body 6 is snapped onto crossbeam 4. Releasing pull ring 504 causes elastic element 505 to spring back, pushing insert rod 502 into the new sign body 6 to complete the fixation. Finally, motor 302 is started again, causing crossbeam 4 and the new sign body 6 to rise to their original positions, completing the replacement of the traffic sign.
