A sliding rod 15 is fixedly connected to one side of the fixing plate 17. A third spring 16 is sleeved on the outside of the sliding rod 15. A base 6 is fixedly connected to the bottom of the fixed column 3. An underground reinforcement component for reinforcement is provided at the bottom of the fixed column 3. The fixed column 3 is used for fixing the entire device. The card slot 2 is used for the connecting column 13 and the clamping block 12 to be inserted into the fixed column 3. The protection fence 1 is fixed between the two connecting columns 13. The sliding column 18, the push plate 19 and the rotating rod 20 cooperate to control the movement of the bolt 21. The third spring 16 is used to make the push plate 19 tightly fit against the inner wall of the protective shell 14 without external force, and also make the bolt 21 tightly inserted into the clamping block 12.
[0035] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the reinforcement component includes a push rod 4. The push rod 4 is slidably connected inside the base 6. A plurality of fixing blocks 10 are fixedly connected to the outside of the push rod 4. A sliding rod 9 is rotatably connected inside the fixing block 10. A plurality of second springs 11 are fixedly connected to the outside of the push rod 4. A housing 5 is slidably connected to the outside of the push rod 4. A plurality of sliding grooves 7 are opened on the outside of the housing 5. A first spring 8 is fixedly connected to the bottom of the push rod 4. The push rod 4 is used to control the movement of the sliding rod 9. The housing 5 is the main body of the underground reinforcement component, ensuring that each component inside it can operate normally. The sliding groove 7 is used for the sliding rod 9 to extend out of the housing 5 and insert into the ground. The second spring 11 acts to push out the sliding rod 9. The bottom first spring 8 is used to tightly abut against the top of the sliding groove 7 after the sliding rod 9 is inserted into the ground. The fixing block 10 is used for the connection between the push rod 4 and the sliding rod 9.
[0036] Referring to Figure 7 , one end of the third spring 16 is fixedly connected to one end of the fixing plate 17, and the other end of the third spring 16 is fixedly connected to one side of the push plate 19. The third spring 16 is used to make the push plate 19 firmly adhere to the inner wall of the protective shell 14 without external force, so that the bolt 21 is tightly inserted into the clamping block 12. The fixing plate 17 is used to carry the third spring 16, and the push plate 19 is used to drive the rotation of the rotating rod 20.
[0037] Referring to Figure 7, the sliding rod 15 is slidably connected inside the sliding column 18, the bolt 21 is slidably connected to the inner wall of the protective case 14. The sliding rod 15 is used to limit the push plate 19, the sliding column 18 is used to push the push plate 19, and the protective case 14 is used to carry each component inside it to ensure normal operation.
[0038] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the sliding rod 9 is slidably connected inside the chute 7. One end of the second spring 11 away from the push rod 4 is fixedly connected to one side of the sliding rod 9. The sliding rod 9 is used to increase the contact area between the bottom of the device and the ground, so as to make the stability better. The chute 7 is used for the telescopic movement of the sliding rod 9.
[0039] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , one end of the first spring 8 away from the push rod 4 is fixedly connected to the inner bottom wall of the outer shell 5. The sliding rod 9 and the outer shell 5 are in mutual contact. The first spring 8 is used to tightly contact the top of the chute 7 when the sliding rod 9 extends outside the chute 7 to ensure no loosening. The push rod 4 is used to push the sliding rod 9, and the outer shell 5 is used to carry each component inside it to ensure normal operation.
[0040] Refer to Figure 1 , Figure 5 and Figure 7 , the bolt 21 is inserted into the inside of the block 12. The block 12 is slidably connected to the inside of the slot 2. The bolt 21 is used to firmly fix the 3 and the connecting column 13, and the slot 2 is used for the insertion of the block 12.
[0041] Refer to Figure 1 , Figure 5 and Figure 4 , the guardrail 1 is slidably connected to the inside of the slot 2. The slot 2 is used for the guardrail 1, the connecting column 13 and the block 12 to slide inside it.
[0042] Working principle: First, insert the outer shell 5 into the ground. After the fixing column 3 and the base 6 are fixed, push the push rod 4 downward. There is a chute 7 on the outer side of the outer shell 5. Then, the sliding rod 9 will be pushed out of the chute 7 by the second spring 11. Under the action of the first spring 8 at the bottom of the push rod 4, the sliding rod 9 will tightly abut against the top of the chute 7, thus realizing the contact area between the whole device and the ground, effectively preventing the fixing column from being blown down in strong winds and heavy rains, and enhancing its stability. Then, push the sliding column 18 on the fixing column 3, and the sliding rod 15 will slide inside the sliding column 18. The push plate 19 connected to the sliding column 18 will slide inside the protective shell 14 accordingly. Both ends of the push plate 19 are rotatably connected to the rotating rod 20, and the other end of the rotating rod 20 is rotatably connected to the bolt 21. While the push plate 19 slides, the bolts 21 will gradually move closer to the middle. After the connecting column 13 fixes the guardrail 1, insert the connecting column 13 into the card slot 2 in the fixing column 3, and then release the sliding column 18. Under the action of the third spring 16 inside it, the push plate 19 will gradually return to its original position, so that the bolts 21 will insert into the clamping blocks 12 on the connecting column 13 to realize its fixation. This device facilitates the installation or disassembly of the guardrail 1 by the staff during replacement or maintenance, effectively improving the work efficiency and reducing unnecessary waste of manpower and material resources.
