[0042] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0043] Combined with the attached Figure 1 , the present utility model is provided with a fixed frame 1. The fixed frame 1 is a square steel frame 1. Inside the fixed frame 1, a number of uniformly distributed rails 2 are provided. A reflective tape 3 is sleeved on the upper end of the rail 2, which is used to reflect light to achieve a warning effect. At both ends of the upper part of the fixed frame 1, a warning light 12 is fixedly connected. Turning on the light can achieve a warning effect at night.

[0044] Combined with the attached Figure 3 , in the middle of the front side of the rail 2, an installation frame 4 is fixedly connected. A slot is opened on the front side of the installation frame 4. A through hole 5 is opened at the upper end of the installation frame 4. A card slot 6 is opened at the bottom end of the installation frame 4. The warning sign 7 is inserted into the installation frame 4 through the through hole 5. The lower end of the warning sign 7 is clamped inside the card slot 6. The warning sign 7 can remind pedestrians of the specific situation ahead, so that pedestrians will not approach blindly after understanding.

[0045] On both ends of the upper part of the front side of the installation frame 4, a clamping mechanism 8 is provided, including a positioning block 8.1, a second threaded rod 8.2, a second threaded rod 8.2, a second knob 8.3, a positioning rod 8.4, and a clamping plate 8.5. On both ends of the upper part of the front side of the installation frame 4, a positioning block 8.1 is fixedly connected. A second threaded rod 8.2 passes through the middle of the positioning block 8.1. The front end of the second threaded rod 8.2 is fixedly connected with a second knob 8.3. Positioning rods 8.4 are arranged on both sides of the positioning block 8.1. The rear ends of the positioning rods 8.4 penetrate through the installation frame 4 and are fixedly connected with a clamping plate 8.5. The rear end of the second threaded rod 8.2 is rotatably connected with the clamping plate 8.5. By turning the second knob 8.3 to drive the second threaded rod 8.2 to rotate, the clamping plate 8.5 can be driven to move back and forth in the through hole 5 in cooperation with the positioning rod 8.4 to fixedly clamp or loosen the warning sign 7, which not only maintains stability but also facilitates the replacement of warning signs 7 with different contents.

[0046] Combined with the attached Figure 2 And the attached Figure 4A locking mechanism 9 is provided at the upper and lower ends of both sides of the installation frame 4, including a lock slot 9.1, a second limiting slot 9.2, a lock rod 9.3, a lock block 9.4, a pull button 9.5, a spring 9.6, a lock plate 9.7, and a lock hole 9.8. A lock slot 9.1 is provided at the upper and lower ends of one side of the fixing frame 1. A second limiting slot 9.2 is provided in the middle of the front side of the lock slot 9.1 and is connected to the lock slot 9.1. A lock rod 9.3 is inserted into the second limiting slot 9.2. A lock block 9.4 is fixedly connected to the rear end of the lock rod 9.3. A pull button 9.5 is fixedly connected to the front end of the lock rod 9.3. A spring 9.6 is sleeved on the outside of the lock rod 9.3 and is provided in the second limiting slot 9.2. Inside, locking plates 9.7 are fixedly connected to the upper and lower ends of the fixing frame 1 away from the locking slot 9.1. The end of the locking plate 9.7 away from the fixing frame 1 is set as an inclined surface, which is convenient for pushing the locking block 9.4 open. A locking hole 9.8 is opened in the middle of the locking plate 9.7. The locking plate 9.7 of one fixing frame 1 can be snapped into the locking slot 9.1 of another fixing frame 1, and snapped into the locking hole 9.8 through the locking block 9.4 for locking and fixing. In this way, multiple sets of warning bars can be connected. When disassembling, you only need to pull the button 9.5 to disengage the locking block 9.4 from the locking hole 9.8 and then pull out the locking plate 9.7. Installation and disassembly are more convenient and quick, and the connection stability is better.

[0047] Fixed blocks 10 are fixedly connected to the lower ends of both sides of the front and the lower ends of both sides of the rear of the installation frame 4, which are used to support the fixed frame 1 to ensure the stability of the warning bar. A lifting mechanism 11 is arranged inside the fixed block 10, including a lifting warehouse 11.1, a limit groove 11.2, a lifting block 11.3, a limit block 11.4, a threaded rod 11.5, a knob 11.6, and a universal wheel 11.7. A lifting warehouse 11.1 is opened inside the fixed block 10, and a limit groove 11.2 is arranged on the front and rear sides of the lifting warehouse 11.1. A lifting block 11.3 is arranged inside the lifting warehouse 11.1, and the lifting block 11.3 is fixedly connected to the limit block 11.4 in the middle of the front and rear ends and is clamped in the limit groove 11. 1.2, a threaded rod 11.5 is rotatably connected to the middle of the upper part of the lifting block 11.3, the upper end of the threaded rod 11.5 passes through the fixed block 10 and is fixedly connected to a knob 11.6, and a universal wheel 11.7 is fixedly connected to the lower part of the lifting block 11.3. By turning the knob 11.6 and the threaded rod 11.5, the lifting block 11.3 can be controlled to move up and down in the lifting warehouse 11.1, thereby driving the universal wheel 11.7 to do lifting and lowering movements. Therefore, when not in use, the universal wheel 11.7 can be retracted into the lifting warehouse 11.1, so that the fixed block 10 is in full contact with the ground, thereby improving the stability of the fixed frame 1, and will not be easily moved due to external force, and the protective effect is good.

[0048] When the utility model is implemented, Figure 1As shown, turn the first knob 11.6 to extend the universal wheel 11.7 out of the lifting bin 11.1 and contact the ground. Push the fixed frame 1 to move the warning rail to the place where warning is needed through the universal wheel 11.7. Then turn the first knob 11.6 again to retract the universal wheel 11.7 into the lifting bin 11.1, so that the fixed block 10 is in full contact with the ground, improving the stability of the fixed frame 1. Push multiple groups of warning rails and lock them to each other through the locking mechanism 9 until the predetermined length is reached. Insert the warning sign 7 into the installation frame 4 through the through hole 5. The lower end of the warning sign 7 is clamped inside the card slot 6 and clamped and fixed through the clamping mechanism 8. The warning sign 7 can remind pedestrians of the specific situation ahead, so that pedestrians will not approach blindly after understanding. During the night, turn on the warning light 12 to cooperate with the reflective tape 3 to achieve the warning effect.
