[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6This utility model provides a technical solution: a movable multi-functional guardrail for municipal road and bridge construction, including a rotating rod 1 and a sleeve rod 4. The sleeve rod 4 is rotatably connected to the outer side of the rotating rod 1, and the sleeve rod 4 rotates along the outer side of the rotating rod 1. A first connecting plate 2 is fixedly connected to the bottom of the rotating rod 1, and a fixing post 5 is fixedly connected to the top of the first connecting plate 2. A mounting box 3 is fixedly connected to the top of the fixing post 5, fixing the first connecting plate 2 and the mounting box 3 together. The top of the sleeve rod 4 extends through one side of the mounting box 3 and is fixedly connected to a third bevel gear 16 inside the mounting box 3. The rotation of the third bevel gear 16 causes the sleeve rod 4 to rotate. A first bevel gear 14 is rotatably connected inside the mounting box 3, and one side of the first bevel gear 14 meshes with the third bevel gear 16. The rotation of the first bevel gear 14 causes the third bevel gear 16 to rotate. The top of the rotating rod 1 is fixedly connected to a second bevel gear 15 through one side of the mounting box 3. The rotation of the rotating rod 1 causes the second bevel gear 15 to rotate. One side of the second bevel gear 15 is meshed with the first bevel gear 14. The rotation of the second bevel gear 15 causes the first bevel gear 14 to rotate. The outer side of the sleeve rod 4 is fixedly connected to a second connecting rod 7. The outer side of the rotating rod 1 is fixedly connected to a first connecting rod 6. The first connecting rod 6 has multiple sets. One end of one set of the first connecting rod 6 is rotatably connected to the sleeve rod 4. The side of the first connecting rod 6 away from the rotating rod 1 is fixedly connected to a second fixing rod 9. The end of the second connecting rod 7 away from the sleeve rod 4 is fixedly connected to a first fixing rod 8 to protect the surrounding environment. The bottom of the second fixing rod 9, the first connecting plate 2, and the first fixing rod 8 are all fixedly connected to casters 24 to better move the whole device.

[0017] Furthermore, a fixed cylinder 12 is fixedly connected to the top of the mounting box 3, and the top of the rotating rod 1 extends through one side of the fixed cylinder 12 into the fixed cylinder 12. A hollow rod 21 is slidably connected to the outside of the rotating rod 1 inside the fixed cylinder 12. The hollow rod 21 moves along the outside of the rotating rod 1. A knob 25 is fixedly connected to the top of the hollow rod 21. The knob 25 moves, causing the hollow rod 21 to move.

[0018] Furthermore, the inner walls of the hollow rod 21 are symmetrically provided with grooves 22 on both sides, and the top of the rotating rod 1 is symmetrically fixedly connected with limiting blocks 23. The outer side of the limiting block 23 is in contact with the groove 22, and the outer side of the limiting block 23 is slidably connected to the groove 22. The limiting block 23 moves along the inside of the groove 22.

[0019] Furthermore, a second connecting plate 20 is slidably connected to the outer side of the rotating rod 1. A spring 19 is fixedly connected between the bottom of the second connecting plate 20 and the mounting box 3. When the second connecting plate 20 moves, it compresses the spring 19. The spring 19 generates elastic force when it is compressed. When the spring 19 loses its compressive force, it returns to its original position with the second connecting plate 20 under the action of the elastic force.

[0020] Furthermore, a first limiting plate 17 is fixedly connected inside the fixed cylinder 12, and a second limiting plate 18 is fixedly connected to one side of the bottom of the hollow rod 21 through the first limiting plate 17. The bottom of the second limiting plate 18 is in contact with the second connecting plate 20. Under the support of the spring 19, one side of the second limiting plate 18 is in contact with the spring 19, which restricts the position of the second limiting plate 18 and prevents the knob 25 from being accidentally touched and causing rotation that affects the angle position of the guardrail.

[0021] Furthermore, a connecting bolt 10 is rotatably connected to one side of the second fixing rod 9, and a connecting post 11 is fixedly connected to one side of the first fixing rod 8. The connecting bolt 10 and the connecting post 11 are detachably connected. A connecting groove is provided at the end of the connecting bolt 10 away from the second fixing rod 9. By rotating the connecting bolt 10, the connecting groove on one side of the connecting bolt 10 comes into contact with the surface of the connecting post 11, thus connecting the connecting bolt 10 and the connecting post 11 together.

[0022] Furthermore, warning signs 13 are fixedly connected to one side of both the first connecting rod 6 and the second connecting rod 7 to remind people in the vicinity.

[0023] In use, after placing the guardrail in a suitable position, press and hold knob 25. Knob 25 moves the hollow rod 21 downwards along the outer side of the rotating rod 1. The movement of the hollow rod 21 causes the second limiting plate 18 to move away from one side of the first limiting plate 17. Rotating knob 25 causes the hollow rod 21 to rotate. With the cooperation of the slide groove 22 and the limiting block 23, the hollow rod 21 rotates the rotating rod 1. The rotation of the rotating rod 1 causes the second bevel gear 15 to rotate. The second bevel gear 15, through the first bevel gear 14, drives the third bevel gear 16 to rotate. The rotation of wheel 16 causes the sleeve rod 4 to rotate, and the rotating rod 1 and sleeve rod 4 rotate in opposite directions, respectively causing the first connecting rod 6 and the second connecting rod 7 on one side to rotate. The first connecting rod 6 and the second connecting rod 7 are adjusted to a suitable angle. When the guardrail needs to be removed, one side of the second fixing rod 9 is aligned with one side of the first fixing rod 8. The connecting bolt 10 is rotated to connect one end of the connecting bolt 10 to the connecting post 11, so that the first connecting rod 6 and the second connecting rod 7 overlap, reducing the volume of the guardrail and facilitating its subsequent handling.
