A middle guardrail 5 is installed on the back of the left guardrail 3 through a hinge, and a right guardrail 4 is installed on the front of the middle guardrail 5 through a hinge. The right guardrail 4 is arranged on the left side of the column 1 close to the right side. The hinge can provide a connection for the two adjacent guardrails, so that the two adjacent guardrails can rotate relative to each other.

[0027] The staff places two upright posts 1 at the designated work location so that the left guardrail 3, the right guardrail 4 and the middle guardrail 5 can be used for interception.

[0028] See also Figure 1 , Figure 2 and Figure 3 A guardrail for municipal engineering that is easy to store, including two transverse grooves 6 on the front and back of the middle guardrail 5, and the two transverse grooves 6 are respectively located near the top and bottom of the middle guardrail 5, and two groups of vertical holes 7 are respectively opened on the inner side of the top wall and the inner side of the bottom wall of the middle guardrail 5, each group has two vertical holes 7, and the vertical holes 7 are connected to the corresponding transverse grooves 6. The middle guardrail 5 can provide a space for the transverse grooves 6 and the vertical holes 7, and the transverse grooves 6 and the vertical holes 7 can provide a space for the thin rod 11 to move. Four square holes are placed through the inner side of the middle guardrail 5. Rod 8, half of the square rod 8 is located on the inner side of the middle guardrail 5, and the other half is located on the inner sides of the left guardrail 3 and the right guardrail 4 respectively. There are two hinges on the back of the left guardrail 3, and the two hinges are respectively located near the top and bottom of the left guardrail 3. The two hinges on the front of the middle guardrail 5 are respectively located near the top and bottom of the middle guardrail 5. A support rod 9 is installed on one side of the square rod 8 through a bearing, and a rotating plate 10 is installed at one end of the support rod 9. A thin rod 11 is installed at the bottom of the rotating plate 10, and the thin rod 11 is placed on the inner side of the vertical hole 7.

[0029] When the staff needs to store, they first grasp the two thin rods 11 near the left side and rotate them toward the front, so that the thin rods 11 rotate toward the front along the inner side of the vertical hole 7 under the action of external force, and the thin rods 11 drive the rotating plate 10 to rotate, so that the rotating plate 10 drives the support rod 9 to rotate, so that the support rod 9 rotates around itself as the center of the circle under the support of the bearing, and the thin rods 11 are rotated from the position of the vertical hole 7 to the inner side of the horizontal groove 6, and then the thin rods 11 are grasped and moved to the right side, so that the thin rods 11 drive the square rods 8 to move, so that the square rods 8 are moved out from the inner side of the left guardrail 3 , move the thin rod 11 along the transverse groove 6 to a position in contact with the right inner wall of the transverse groove 6, so that the square rod 8 is completely moved to the inner side of the middle guardrail 5, loosen the thin rod 11, and allow the thin rod 11 to rotate to the inner side of the other vertical hole 7 under the action of its own weight. Similarly, operate the two thin rods 11 close to the right side, then grab the left guardrail 3 and rotate it toward the back with the hinge on the back as the center of the circle, rotate the left guardrail 3 to the back of the middle guardrail 5, grab the right guardrail 4 and rotate it toward the front to the front of the middle guardrail 5, so as to realize folding and storage of the guardrails.

[0030] See also Figure 1 , Figure 4 and Figure 5 A guardrail for municipal engineering that is easy to store, including a fixing plate 2, two groups of fixing plates 2 are respectively installed on the sides of two columns 1 close to each other, each group has two fixing plates 2, and the fixing plates 2 are respectively mounted on the front and back sides of the left guardrail 3 and the right guardrail 4, a movable groove 12 is opened at the bottom of the column 1, a column groove 13 is opened on the inner side of the top wall of the movable groove 12, a threaded groove 14 is opened on the inner side of the column groove 13, a threaded plate 15 is threadedly installed on the inner side of the threaded groove 14, a rotating rod 16 is installed on the top of the threaded plate 15, and the rotating rod 1 6 is placed inside the column groove 13 near the top, a decorative ball 17 is installed on the top of the rotating rod 16, and the decorative ball 17 can play a decorative role, and it is more natural when matched with the grab bar 18. Grab bars 18 are installed on both sides of the rotating rod 16, and a rotating shaft 19 is installed at the bottom of the threaded plate 15, and the rotating shaft 19 is placed inside the column groove 13 near the bottom. A circular plate 20 is installed at one end of the rotating shaft 19, and the circular plate 20 is located on the inner side of the movable groove 12, and a universal wheel 21 is installed at the bottom of the circular plate 20.

[0031] The staff grabs the two grab bars 18 and rotates them, so that the two grab bars 18 drive the rotating rod 16 to rotate with the rotating rod 16 as the center, and drives the threaded plate 15 to rotate through the rotating rod 16. The threaded plate 15 can rotate freely independently of the rotating shaft 19 through the bearing at the bottom. The rotation of the threaded plate 15 drives the column 1 to move upward by utilizing the threaded action with the threaded groove 14. The column 1 is connected to the left guardrail 3 and the right guardrail 4 through the fixed plate 2, which can prevent the column 1 from rotating and facilitate the up and down movement of the column 1. The column 1 moves upward and no longer contacts the ground, so that the universal wheel 21 contacts the ground. After both columns 1 are moved upward, it is convenient for the column 1 to drive the left guardrail 3 or the right guardrail 4 to move. It is more convenient to store with the storage component, and it is also convenient to move the device to a designated position, saving manpower.

[0032] Working principle: Before using the device, check whether there are any problems that affect its use. When the staff needs to use the device, they should first grasp the two rotating rods 16 on the top of the two columns 1 and rotate them, move the two columns 1 upward, and move them to the designated position through the universal wheels 21. When storing, grasp the thin rod 11 and rotate it from the vertical hole 7 to the inside of the horizontal groove 6, and then rotate it to the inside of another vertical hole 7, and rotate the left guardrail 3 and the right guardrail 4 with the hinge connected to the middle guardrail 5 as the center of the circle, and fold the left guardrail 3 and the right guardrail 4 through the universal wheels 21 for storage.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
